GENERAL DESCRIPTION
The ADV601LC is an ultralow cost, single chip, dedicated function, all digital CMOS VLSI device capable of supporting visually loss-less to 350:1 real-time compression and decom­pression of CCIR-601 digital video at very high image quality levels. The chip integrates glueless video and host interfaces with on-chip SRAM to permit low part count, system level implementations suitable for a broad range of applications. The ADV601LC is 100% bitstream compatible with the ADV601.
The ADV601LC is a video encoder/decoder optimized for real­time compression and decompression of interlaced digital video. All features of the ADV601LC are designed to yield high perfor­mance at a breakthrough systems-level cost. Additionally, the unique sub-band coding architecture of the ADV601LC offers you many application-specific advantages. A review of the Gen­eral Theory of Operation and Applying the ADV601LC sections will help you get the most use out of the ADV601LC in any given application.
The ADV601LC accepts component digital video through the Video Interface and outputs a compressed bit stream though the Host Interface in Encode Mode. While in Decode Mode, the ADV601LC accepts a compressed bit stream through the Host Interface and outputs component digital video through the Video Interface. The host accesses all of the ADV601LC’s con­trol and status registers using the Host Interface. Figure 1 sum­marizes the basic function of the part.

The ADV601LC adheres to international standard CCIR-601 for studio quality digital video. The codec also supports a range of field sizes and rates providing high performance in computer, PAL, NTSC, or still image environments. The ADV601LC is designed only for real-time interlaced video, full frames of video are formed and processed as two independent fields of data. The ADV601LC supports the field rates and sizes in Table I. Note that the maximum active field size is 768 by 288. The maximum pixel rate is 14.75 MHz.
The ADV601LC has a generic 16-/32-bit host interface, which includes a 512-position, 32-bit wide FIFO for compressed video. With additional external hardware, the ADV601LC’s host inter­face is suitable (when interfaced to other devices) for moving com­pressed video over PCI, ISA, SCSI, SONET, 10 Base T, ARCnet, HDSL, ADSL, and a broad range of digital interfaces. For a full description of the Host Interface, see the Host Interface section.
The compressed data rate is determined by the input data rate and the selected compression ratio. The ADV601LC can achieve a near constant compressed bit rate by using the current field statistics in the off-chip bin width calculator on the external DSP or Host. The process of calculating bin widths on a DSP or Host can be “adaptive,” optimizing the compressed bit rate in real time. This feature provides a near constant bit rate out of the host interface in spite of scene changes or other types of source material changes that would otherwise create bit rate burst conditions. For more information on the quantizer, see the Programmable Quantizer section.
The ADV601LC typically yields visually loss-less compression on natural images at a 4:1 compression ratio. Desired image quality levels can vary widely in different applications, so it is advisable to evaluate image quality of known source material at different compression ratios to find the best compression range for the application. The sub-band coding architecture of the ADV601LC provides a number of options to stretch compres­sion performance. These options are outlined on in the Apply­ing the ADV601LC section.

ADV601LC

INTERNAL ARCHITECTURE

The ADV601LC is composed of eight blocks. Three of these blocks are interface blocks and five are processing blocks. The interface blocks are the Digital Video I/O Port, the Host I/O Port, and the external DRAM manager. The processing blocks are the Wavelet Kernel, the On-Chip Transform Buffer, the Programmable Quantizer, the Run Length Coder, and the Huffman Coder.
Digital Video I/O Port
Provides a real-time uncompressed video interface to support a broad range of component digital video formats, including “D1.”
Host I/O Port and FIFO
Carries control, status, and compressed video to and from the host processor. A 512 position by 32-bit FIFO buffers the com­pressed video stream between the host and the Huffman Coder.
DRAM Manager
Performs all tasks related to writing, reading, and refreshing the external DRAM. The external host buffer DRAM is used for reordering and buffering quantizer input and output values.
Wavelet Kernel (Filters, Decimator, and Interpolator)
Gathers statistics on a per field basis and includes a block of filters, interpolators, and decimators. The kernel calculates forward and backward bi-orthogonal, two-dimensional, sepa­rable wavelet transforms on horizontal scanned video data. This block uses the internal transform buffer when performing wave­let transforms calculated on an entire image’s data and so eliminates any need for extremely fast external memories in an ADV601LC-based design.
On-Chip Transform Buffer
Provides an internal set of SRAM for use by the wavelet trans­form kernel. Its function is to provide enough delay line storage to support calculation of separable two dimensional wavelet transforms for horizontally scanned images.
Programmable Quantizer
Quantizes wavelet coefficients. Quantize controls are calculated by the external DSP or host processor during encode operations and de-quantize controls are extracted from the compressed bit stream during decode. Each quantizer Bin Width is computed by the BW calculator software to maintain a constant com­pressed bit rate or constant quality bit rate. A Bin Width is a per block parameter the quantizer uses when determining the num­ber of bits to allocate to each block (sub-band).
Run Length Coder
Performs run length coding on zero data and models nonzero data, encoding or decoding for more efficient Huffman coding. This data coding is optimized across the sub-bands and varies depending on the block being coded.
Huffman Coder
Performs Huffman coder and decoder functions on quantized run-length coded coefficient values. The Huffman coder/de­coder uses three ROM-coded Huffman tables that provide ex­cellent performance for wavelet transformed video.
GENERAL THEORY OF OPERATION
The ADV601LC processor’s compression algorithm is based on the bi-orthogonal (7, 9) wavelet transform, and implements field independent sub-band coding. Sub-band coders transform two­dimensional spatial video data into spatial frequency filtered sub-bands. The quantization and entropy encoding processes provide the ADV601LC’s data compression.
The wavelet theory, on which the ADV601LC is based, is a new mathematical apparatus first explicitly introduced by Morlet and Grossman in their works on geophysics during the mid 80s. This theory became very popular in theoretical physics and applied math. The late 80s and 90s have seen a dramatic growth in wavelet applications such as signal and image processing. For more on wavelet theory by Morlet and Grossman, see Decompo-
sition of Hardy Functions into Square Integrable Wavelets of Con­stant Shape (journal citation listed in References section).

THE WAVELET KERNEL

This block contains a set of filters and decimators that work on the image in both horizontal and vertical directions. Figure 6 illustrates the filter tree structure. The filters apply carefully chosen wavelet basis functions that better correlate to the broad­band nature of images than the sinusoidal waves used in Dis­crete Cosine Transform (DCT) compression schemes (JPEG, MPEG, and H261).
An advantage of wavelet-based compression is that the entire image can be filtered without being broken into sub-blocks as required in DCT compression schemes. This full image filtering eliminates the block artifacts seen in DCT compression and offers more graceful image degradation at high compression ratios. The availability of full image sub-band data also makes image processing, scaling, and a number of other system fea­tures possible with little or no computational overhead.
The resultant filtered image is made up of components of the original image as is shown in Figure 3 (a modified Mallat Tree). Note that Figure 3 shows how a component of video would be filtered, but in multiple component video luminance and color components are filtered separately. In Figure 4 and Figure 5 an actual image and the Mallat Tree (luminance only) equivalent is shown. It is important to note that while the image has been filtered or transformed into the frequency domain, no compres­sion has occurred. With the image in its filtered state, it is now ready for processing in the second block, the quantizer.
Understanding the structure and function of the wavelet filters and resultant product is the key to obtaining the highest perfor­mance from the ADV601LC. Consider the following points:
The data in all blocks (except N) for all components are high pass filtered. Therefore, the mean pixel value in those blocks is typically zero and a histogram of the pixel values in these blocks will contain a single “hump” (Laplacian distribution).
The data in most blocks is more likely to contain zeros or strings of zeros than unfiltered image data.
The human visual system is less sensitive to higher frequency blocks than low ones.
Attenuation of the selected blocks in luminance or color com­ponents results in control over sharpness, brightness, contrast and saturation.
High quality filtered/decimated images can be extracted/created without computational overhead.
Through leverage of these key points, the ADV601LC not only compresses video, but offers a host of application features. Please see the Applying the ADV601LC section for details on getting the most out of the ADV601LC’s sub-band coding architecture in different applications.

THE PROGRAMMABLE QUANTIZER

This block quantizes the filtered image based on the response profile of the human visual system. In general, the human eye cannot resolve high frequencies in images to the same level of accuracy as lower frequencies. Through intelligent “quantiza­tion” of information contained within the filtered image, the ADV601LC achieves compression without compromising the visual quality of the image. Figure 7 shows the encode and de­code data formats used by the quantizer.
Figure 8 shows how a typical quantization pattern applies over Mallat block data. The high frequency blocks receive much larger quantization (appear darker) than the low frequency blocks (appear lighter). Looking at this figure, one sees some key point concerning quantization: (1) quantization relates directly to frequency in Mallat block data and (2) levels of quantization range widely from high to low frequency block. (Note that the fill is based on a log formula.) The relation between actual ADV601LC bin width factors and the Mallat block fill pattern in Figure 8 appears in Table II.

THE RUN LENGTH CODER AND HUFFMAN CODER

This block contains two types of entropy coders that achieve mathematically loss-less compression: run length and Huffman. The run-length coder looks for long strings of zeros and replaces it with short hand symbols. Table III illustrates an example of how compression is possible.
The Huffman coder is a digital compressor/decompressor that can be used for compressing any type of digital data. Essentially, an ideal Huffman coder creates a table of the most commonly occurring code sequences (typically zero and small values near zero) and then replaces those codes with some shorthand. The ADV601LC employs three fixed Huffman tables; it does not create tables.
The filters and the quantizer increase the number of zeros and strings of zeros, which improves the performance of the entropy coders. The higher the selected compression ratio, the more zeros and small value sequences the quantizer needs to generate. The transformed image in Figure 5 shows that the filter bank concentrates zeros and small values in the higher frequency blocks.
Encoding vs. Decoding
The decoding of compressed video follows the exact path as encoding but in reverse order. There is no need to calculate Bin Widths during decode because the Bin Width is stored in the compressed image during encode.

PROGRAMMER’S MODEL

A host device configures the ADV601LC using the Host I/O Port. The host reads from status registers and writes to control registers through the Host I/O Port.

Direct (Write) Register Byte Offset 0x00. This register holds a 16-bit value (index) that selects the indirect register accessible to the host through the indirect data register. All
indirect write registers are 16 bits wide. The address in this register is auto-incremented on each subsequent access of the indirect data register. This capability enhances I/O performance during modes of operation where the host is calculating Bin Width controls.
[15:0] Indirect Address Register, IAR[15:0]. Holds a 16-bit value (index) that selects the indirect register to read or write through
the indirect data register (undefined at reset)

Direct (Read/Write) Register Byte Offset 0x04 This register holds a 16-bit value read or written from or to the indirect register indexed by the Indirect Address Register. [15:0] Indirect Register Data, IRD[15:0]. A 16-bit value read or written to the indexed indirect register. Undefined at reset. [31:16] Reserved (undefined read/write zero)
Compressed Data Register
Direct (Read/Write) Register Byte Offset 0x08 This register holds a 32-bit sequence from the compressed video bit stream. This register is buffered by a 512 position, 32-bit FIFO.
For Word (16-bit) accesses, access Word0 (Byte 0 and Byte 1) then Word1 (Byte 2 and Byte 3) for correct auto-increment. For a description of the data sequence, see the Compressed Data Stream Definition section.
[31:0] Compressed Data Register, CDR[31:0]. 32-bit value containing compressed video stream data. At reset, contents undefined.
Interrupt Mask / Status Register
Direct (Read/Write) Register Byte Offset 0x0C This 16-bit register contains interrupt mask and status bits that control the state of the ADV601LC’s HIRQ pin. With the seven
mask bits (IE_LCODE, IE_STATSR, IE_FIFOSTP, IE_FIFOSRQ, IE_FIFOERR, IE_CCIRER, IE_MERR); select the conditions that are ORed together to determine the output of the HIRQ pin.
Six of the status bits (LCODE, STATSR, FIFOSTP, MERR, FIFOERR, CCIRER) indicate active interrupt conditions and are sticky bits that stay set until read. Because sticky status bits are cleared when read, and these bits are set on the positive edge of the condition coming true, they cannot be read or tested for stable level true conditions multiple times.
The FIFOSRQ bit is not sticky. This bit can be polled to monitor for a FIFOSRQ true condition. Note: Enable this monitoring by using the FIFOSRQ bit and correctly programming DSL and ESL fields within the FIFO control registers.
[0] CCIR-656 Error in CCIR-656 data stream, CCIRER. This read only status bit indicates the following:
0 No CCIR-656 Error condition, reset value 1 Unrecoverable error in CCIR-656 data stream (missing sync codes)
[1] Statistics Ready, STATSR. This read only status bit indicates the following:
0 No Statistics Ready condition, reset value (STATS_R pin LO) 1 Statistics Ready for BW calculator (STATS_R pin HI)
[2] Last Code Read, LCODE. This read only status bit indicates the last compressed data word for field will be
retrieved from the FIFO on the next read from the host bus. 0 No Last Code condition, reset value (LCODE pin LO)
1 Next read retrieves last word for field in FIFO (LCODE pin HI)
[3] FIFO Service Request, FIFOSRQ. This read only status bit indicates the following:

ADV601LC
[4] FIFO Error, FIFOERR. This condition indicates that the host has been unable to keep up with the ADV601LC’s compressed
data supply or demand requirements. If this condition occurs during encode, the data stream will not be corrupted until MERR indicates that the DRAM is also overflowed. If this condition occurs during decode, the video output will be corrupted. If the system overflows the FIFO (disregarding a FIFOSTP condition) with too many writes in decode mode, FIFOERR is asserted. This read only status bit indicates the following:
0 No FIFO Error condition, reset value (FIFO_ERR pin LO) 1 FIFO overflow (encode) or underflow (decode) (FIFO_ERR pin HI)
[5] FIFO Stop, FIFOSTP. This condition indicates that the FIFO is full in decode mode and empty in encode mode.
In decode mode only, FIFOSTP status actually behaves more conservatively than this. In decode mode, even when FIFOSTP is indicated, there are still 32 empty Dwords available in the FIFO and 32 more Dword writes can safely be performed. This status bit indicates the following:
0 No FIFO Stop condition, reset value (FIFO_STP pin LO) 1 FIFO empty (encode) or full (decode) (FIFO_STP pin HI)
[6] Memory Error, MERR. This condition indicates that an error has occurred at the DRAM memory interface. This condition can
be caused by a defective DRAM, the inability of the Host to keep up with the ADV601LC compressed data stream, or bit errors in the data stream. Note that the ADV601LC recovers from this condition without host intervention.
0 No memory error condition, reset value

0 Normal operation
1 Software Reset. This b i t i s set on hardware reset and mu st be cleared before the ADV601LC can begin processing. (reset value)
When this bit i s set during encode, the ADV601LC completes processing the current field then suspends operation until the SWR bit is cleared. When this bit is set during decode, the ADV601LC suspends operation immediately and does not resume operation until the SWR bi t i s cl eared. Note th at this bit must be set whenever any other bit in the Mode register is changed.

0 HIRQ is active LO, reset value
1 HIRQ is active HI [15:14] Reserved (always write zero)
FIFO Control Register
Indirect (Read/Write) Register Index 0x01 This register holds the service-request settings for the ADV601LC’s host interface FIFO, causing interrupts for the “nearly full” and
“nearly empty” levels. Because each register is four bits in size, and the FIFO is 512 positions, the 4-bit value must be multiplied by 32 (decimal) to determine the exact value for encode service level (nearly full) and decode service level (nearly empty). The ADV601LC uses these setting to determine when to generate a FIFO Service Request related host interrupt (FIFOSRQ bit and FIFO_SRQ pin).
[3:0] Encode Service Level, ESL[3:0]. The value in this field determines when the FIFO is considered nearly full on encode; a condi-
tion that generates a FIFO service request condition in encode mode. Since this register is four bits (16 states), and the FIFO is
512 positions, the step size for each bit in this register is 32 positions. The following table summarizes sample states of the
register and their meaning.
ESL Interrupt When . . .

VIDEO AREA REGISTERS

The area defined by the HSTART, HEND, VSTART and VEND registers is the active area that the wavelet kernel processes. Video data outside the active video area is set to minimum luminance and zero chrominance (black) by the ADV601LC. These registers allow cropping of the input video during compression (encode only), but do not change the image size. Figure 10 shows how the video area registers work together.
Some comments on how these registers work are as follows:
0, 0
• The vertical numbers include the blanking areas of the video. Specifically, a VSTART value of 21 will include the first line
VSTART
of active video, and the first pixel in a line corresponds to a value HSTART of 0 (for NTSC regular).
Note that the vertical coordinates start with 1, whereas the horizontal coordinates start with 0.
• The default cropping mode is set for the entire frame. Specifi­cally, Field 2 starts at a VSTART value of 283 (for NTSC
VEND
regular).

each field. The VSTART and VEND contents must be updated on each field. Perform this updating as part of the field-by-field BW regis­ter update process. To perform this dynamic update correctly, the update software must keep track of which field is being processed next.

Sum of Squares [0–41] Registers
Indirect (Read Only) Register Index 0x080 through 0x0A9 The Sum of Squares [0–41] registers hold values that correspond to the summation of values (squared) in corresponding Mallat
blocks [0–41]. These registers let the Host or DSP read sum of squares statistics from the ADV601LC; using these values (with the Sum of Value, MIN Value, and MAX Value) the host or DSP can then calculate the BW and RBW values. The ADV601LC indi­cates that the sum of squares statistics have been updated by setting (1) the STATR bit and asserting the STAT_R pin. Read the statistics at any time. The Host reads these values through the Host Interface.
[15:0] Sum of Squares, STS[15:0]. 16-bit values [0-41] for corresponding Mallat blocks [0-41] (undefined at reset). Sum of Square
values are 16-bit codes that represent the Most Significant Bits of values ranging from 40 bits for small blocks to 48 bits for large blocks. The 16-bit codes have the following precision:

Name Pins I/O Description
VCLK/XTAL 2 I A single clock (VCLK) or crystal input (across VCLK and XTAL). An acceptable
50% duty cycle clock signal is 27 MHz (CCIR-601 NTSC/PAL). If using a clock crystal, use a parallel resonant, microprocessor grade clock crystal. If
using a clock input, use a TTL level input, 50% duty cycle clock with 1 ns (or less) jitter (measured rising edge to rising edge). Slowly varying, low jitter clocks are acceptable; up to 5% frequency variation in 0.5 sec.
VCLKO 1 O VCLK Output or VCLK Output divided by two. Select function using Mode
Control register.
Video Interface Pins
Name Pins I/O Description
VSYNC 1 I or O Vertical Sync or Vertical Blank. This pin can be either an output (Master Mode) or
an input (Slave Mode). The pin operates as follows:
Output (Master) HI during inactive lines of video and LO otherwise
Input (Slave) a HI on this input indicates inactive lines of video
HSYNC 1 I or O Horizontal Sync or Horizontal Blank. This pin can be either an output (Master
Mode) or an input (Slave Mode). The pin operates as follows:
Output (Master) HI during inactive portion of video line and LO otherwise
Input (Slave) a HI on this input indicates inactive portion of video line
Note that the polarity of this signal is modified using the Mode Control register. For detailed timing information, see the Video Interface section.
FIELD 1 I or O Field # or Frame Sync. This pin can be either an output (Master Mode) or an input
(Slave Mode). The pin operates as follows:
Output (Master) HI during Field1 lines of video and LO otherwise
Input (Slave) a HI on this input indicates Field1 lines of video
ENC 1 O Encode or Decode. This output pin indicates the coding mode of the ADV601LC
and operates as follows:
LO Decode Mode (Video Interface is output)
HI Encode Mode (Video Interface is input)
Note that this pin can be used to control bus enable pins for devices connected to the ADV601LC Video Interface.
VDATA[7:0] 8 I/O 4:2:2 Video Data (8-bit digital component video data). These pins are inputs during
encode mode and outputs during decode mode. When outputs (decode) these pins are compatible with 50 pF loads (rather than 30 pF as all other busses) to meet the high performance and large number of typical loads on this bus.
The performance of these pins varies with the Video Interface Mode set in the Mode Control register, see the Video Interface section of this data sheet for pin assignments in each mode.
Note that the Mode Control register also sets whether the color component is treated as either signed or unsigned.

DRAM Interface Pins
Name Pins I/O Description
DDAT[15:0] 16 I/O DRAM Data Bus. The ADV601LC uses these pins for 16-bit data read/write
operations to the external 256K × 16-bit DRAM. (The operation of the DRAM interface is fully automatic and controlled by internal functionality of the ADV601LC.) These pins are compatible with 30 pF loads.
DADR[8:0] 9 O DRAM Address Bus. The ADV601LC uses these pins to form the multiplexed
row/column address lines to the external DRAM. (The operation of the DRAM interface is fully automatic and controlled by internal functionality of the ADV601LC.) These pins are compatible with 30 pF loads.
RAS 1 O DRAM Row Address Strobe. This pin is compatible with 30 pF loads. CAS 1 O DRAM Column Address Strobe. This pin is compatible with 30 pF loads. WE 1 O DRAM Write Enable. This pin is compatible with 30 pF loads.
Note that the ADV601LC does not have a DRAM OE pin. Tie the DRAM’s OE pin to ground.
Host Interface Pins
Name Pins I/O Description
DATA[31:0] 32 I/O Host Data Bus. These pins make up a 32-bit wide host data bus. The host
controls this asynchronous bus with the WR, RD, BE, and CS pins to commu­nicate with the ADV601LC. These pins are compatible with 30 pF loads.
ADR[1:0] 2 I Host DWord Address Bus. These two address pins let you address the
ADV601LC’s four directly addressable host interface registers. For an illustra­tion of how this addressing works, see the Control and Write Register Map figure and Status and Read Register Map figure. The ADR bits permit register addressing as follows:
ADR1 ADR0 DWord Address Byte Address 0 0 0 0x00 0 1 1 0x04 1 0 2 0x08 1 1 3 0x0C
BE0BE3 2 I Host Word Enable pins. These two input pins select the words that the
ADV601LC’s direct and indirect registers access through the Host Interface; BE0BE1 access the least significant word, and BE2BE3 access the most significant word. For a 32-bit interface only, tie these pins to ground, making all words available.
Some important notes for 16-bit interfaces are as follows:
When using these byte enable pins, the byte order is always the lowest byte
to the higher bytes.
The ADV601LC advances to the next 32-bit compressed data FIFO location
after the BE2BE3 pin is asserted then de-asserted (when accessing the Com-
pressed Data register); so the FIFO location only advances when and if the
host reads or writes the MSW of a FIFO location.
The ADV601LC advances to the next 16-bit indirect register after the BE0BE1
pin is asserted then de-asserted; so the register selection only advances when
and if the host reads or writes the MSW of a 16-bit indirect register.
CS 1 I Host Chip Select. This pin operates as follows:
LO Qualifies Host Interface control signals
HI Three-states DATA[31:0] pins
WR 1 I Host Write. Host register writes occur on the rising edge of this signal. RD 1 I Host Read. Host register reads occur on the low true level of this signal.

ADV601LC
Host Interface Pins (Continued)
Name Pins I/O Description
ACK 1 O Host Acknowledge. The ADV601LC acknowledges completion of a Host Interface
access by asserting this pin. Most Host Interface accesses (other than the com­pressed data register access) result in ACK being held high for at least one wait cycle, but some exceptions to that rule are as follows:
A full FIFO during decode operations causes the ADV601LC to de-assert
(drive HI) the ACK pin, holding off further writes of compressed data until
the FIFO has one available location.
An empty FIFO during encode operations causes the ADV601LC to de-assert
(drive HI) the ACK pin, holding off further reads until one location is filled.
FIFO_SRQ 1 O FIFO Service Request. This pin is an active high signal indicating that the FIFO
needs to be serviced by the host. (see FIFO Control register). The state of this pin also appears in the Interrupt Mask/Status register. Use the interrupt mask to assert a Host interrupt (HIRQ pin) based on the state of the FIFO_SRQ pin. This pin oper­ates as follows:
LO No FIFO Service Request condition (FIFOSRQ bit LO)
HI FIFO needs service is nearly full (encode) or nearly empty (decode)
During encode, FIFO_SRQ is LO when the SWR bit is cleared (0) and goes HI when the FIFO is nearly full (see FIFO Control register).
During decode, FIFO_SRQ is HI when the SWR bit is cleared (0), because FIFO is empty, and goes LO when the FIFO is filled beyond the nearly empty condition (see FIFO Control register).
STATS_R 1 O Statistics Ready. This pin indicates the Wavelet Statistics (contents of Sum of
Squares, Sum of Value, MIN Value, MAX Value registers) have been updated and are ready for the Bin Width calculator to read them from the host interface. The frequency of this interrupt will be equal to the field rate. The state of this pin also appears in the Interrupt Mask/Status register. Use the interrupt mask to assert a Host interrupt (HIRQ pin) based on the state of the STATS_R pin. This pin oper­ates as follows:
LO No Statistics Ready condition (STATSR bit LO)
HI Statistics Ready for BW calculator (STATSR bit HI)
LCODE 1 O Last Compressed Data (for field). This bit indicates the last compressed data word
for field will be retrieved from the FIFO on the next read from the host bus. The frequency of this interrupt is similar to the field rate, but varies depending on compression and host response. The state of this pin also appears in the Interrupt Mask/Status register. Use the interrupt mask to assert a Host interrupt (HIRQ pin) based on the state of the LCODE pin. This pin operates as follows:
LO No Last Code condition (LCODE bit LO)
HI Last data word for field has been read from FIFO (LCODE bit HI)
HIRQ 1 O Host Interrupt Request. This pin indicates an interrupt request to the Host. The
Interrupt Mask/Status register can select conditions for this interrupt based on any or all of the following: FIFOSTP, FIFOSRQ, FIFOERR, LCODE, STATR or CCIR-656 unrecoverable error. Note that the polarity of the HIRQ pin can be modified using the Mode Control register.
RESET 1 I ADV601LC Chip Reset. Asserting this pin returns all registers to reset state. Note

ADV601LC
Video Interface
The ADV601LC video interface supports two types of compo­nent digital video (D1) interfaces in both compression (input) and decompression (output) modes. These digital video inter­faces include support for the Multiplexed Philips 4:2:2 and CCIR-656/SMPTE125M—international standard.
Video interface master and slave modes allow for the generation or receiving of synchronization and blanking signals. Definitions for the different formats can be found later in this section. For recommended connections to popular video decoders and encoders, see the Connecting The ADV601LC To Popular Video Decoders and Encoders section. A complete list of supported video interfaces and sampling rates is included in Table V.

Philips 8 YUV 4:2:2 27 8
Internally, the video interface translates all video formats to one consistent format to be passed to the wavelet kernel. This con­sistent internal video standard is 4:2:2 at 16 bits accuracy.
VITC and Closed Captioning Support
The video interface also supports the direct loss-less extraction of 90-bit VITC codes during encode and the insertion of VITC codes during decode. Closed Captioning data (found on active Video Line 21) is handled just as normal active video on an active scan line. As a result, no special dedicated support is necessary for Closed Captioning. The data rates for Closed Captioning data are low enough to ensure robust operation of this mechanism at compression ratios of 50:1 and higher. Note that you must include Video Line 21 in the ADV601LC’s de­fined active video area for Closed Caption support.
27 MHz Nominal Sampling
There is one clock input (VCLK) to support all internal process­ing elements. This is a 50% duty cycle signal and must be syn­chronous to the video data. Internally this clock is doubled using a phase locked loop to provide for a 54 MHz internal processing clock. The clock interface is a two pin interface that allows a crystal oscillator to be tied across the pins or a clock oscillator to drive one pin. The nominal clock rate for the video interface is 27 MHz. Note that the ADV601LC also supports a pixel rate of
13.5 MHz.
Video Interface and Modes
In all, there are seven programmable features that configure the video interface. These are:
• Encode-Decode Control
In addition to determining what functions the internal pro­cessing elements must perform, this control determines the direction of the video interface. In decode mode, the video interface outputs data. In encode mode, the interface receives data. The state of the control is reflected on the ENC pin. This pin can be used as an enable input by external line driv­ers. This control is maintained by the host processor.
• Master-Slave Control
This control determines whether the ADV601LC generates or
receives the VSYNC, HSYNC, and FIELD signals. In master mode, the ADV601LC generates these signals for external hardware synchronization. In slave mode, the ADV601LC receives these signals. Note that some video formats require the ADV601LC to operate in slave mode only. This control is maintained by the host processor.
• 525-625 (NTSC-PAL) Control
This control determines whether the ADV601LC is operating on 525/NTSC video or 625/PAL video. This information is used when the ADV601LC is in master and decode modes so that the ADV601LC knows where and when to generate the HSYNC, VSYNC, and FIELD Pulses as well as when to insert the SAV and EAV time codes (for CCIR-656 only) in the data stream. This control is maintained by the host pro­cessor. Table VI shows how the 525-625 Control in the Mode Control register works.
Table VI. Square Pixel Control, 525-625 Control, and Video Formats
Max Max 525-625 Horizontal Field Control Size Size NTSC-PAL
0 720 243 CCIR-601 NTSC 1 720 288 CCIR-601 PAL
• Bipolar/Unipolar Color Component
This mode determines whether offsets are used on color com­ponents. In Philips mode, this control is usually set to Bipo­lar, since the color components are normal twos-compliment signed values. In CCIR-656 mode, this control is set to Uni­polar, since the color components are offset by 128. Note that it is likely the ADV601LC will function if this control is in the wrong state, but compression performance will be degraded. It is important to set this bit correctly.
• Active Area Control
Four registers HSTART (horizontal start), HEND (horizon­tal end), VSTART (vertical start) and VEND (vertical end) determine the active video area. The maximum active video area is 720 by 288 pixels for a single field.
• Video Format
This control determines the video format that is supported. In general, the goal of the various video formats is to support glueless interfaces to the wide variety of video formats periph­eral components expect. This control is maintained by the host processor. Table VII shows a synopsis of the supported video formats. Definitions of each format can be found later in this section. For Video Interface pins descriptions, see the Pin Function Descriptions.

ADV601LC
Clocks and Strobes
All video data is synchronous to the video clock (VCLK). The rising edge of VCLK is used to clock all data into the ADV601LC.
Synchronization and Blanking Pins
Three signals, which can be configured as inputs or outputs, are used for video frame and field horizontal synchronization and blanking. These signals are VSYNC, HSYNC, and FIELD.
VDATA Pins Functions With Differing Video Interface Formats
The functionality of the Video Interface pins depends on the current video format. Table VIII defines how Video data pins are used for the various formats.
Table VII. Component Digital Video Formats

Video Formats—CCIR-656
The ADV601LC supports a glueless video interface to CCIR-656 devices when the Video Format is programmed to CCIR-656 mode. CCIR-656 requires that 4:2:2 data (8 bits per compo­nent) be multiplexed and transmitted over a single 8-bit physical interface. A 27 MHz clock is transmitted along with the data. This clock is synchronous with the data. The color space of CCIR-656 is YCrCb.
When in master mode, the CCIR-656 mode does not require any external synchronization or blanking signals to accompany digital video. Instead, CCIR-656 includes special time codes in the stream syntax that define horizontal blanking periods, verti­cal blanking periods, and field synchronization (horizontal and vertical synchronization information can be derived). These time codes are called End-of-Active-Video (EAV) and Start-of­Active-Video (SAV). Each line of video has one EAV and one SAV time code. EAV and SAV have three bits of embedded information to define HSYNC, VSYNC and Field information as well as error detection and correction bits.

VCLK is driven with a 27 MHz, 50% duty cycle clock which is synchronous with the video data. Video data is clocked on the rising edge of the VCLK signal. When decoding, the VCLK signal is typically transmitted along with video data in the CCIR-656 physical interface.
Electrically, CCIR-656 specifies differential ECL levels to be used for all interfaces. The ADV601LC, however, only supports unipolar, TTL logic thresholds. Systems designs that interface to strictly conforming CCIR-656 devices (especially when inter­facing over long cable distances) must include ECL level shifters and line drivers.
The functionality of HSYNC, VSYNC and FIELD Pins is dependent on three programmable modes of the ADV601LC: Master-Slave Control, Encode-Decode Control and 525-625 Control. Table IX summarizes the functionality of these pins in various modes.

HSYNC, VSYNC and FIELD Master Mode (HSYNC, VSYNC Slave Mode (HSYNC, VSYNC Functionality for CCIR-656 and FIELD Are Outputs) and FIELD Are Inputs)
Encode Mode (video data is input Pins are driven to reflect the states of the Undefined—Use Master Mode to the chip) received time codes: EAV and SAV. This
functionality is independent of the state of the 525-625 mode control. An encoder is most likely to be in master mode.
Decode Mode (video data is output Pins are output to the precise timing definitions Undefined—Use Master Mode from the chip) for CCIR-656 interfaces. The state of the pins
reflect the state of the EAV and SAV timing codes that are generated in the output video data. These definitions are different for 525 and 625 line systems. The ADV601LC completely manages the generation and timing of these pins.

ADV601LC
Video Formats — Multiplexed Philips Video
The ADV601LC supports a hybrid mode of operation that is a cross between standard dual lane Philips and single lane CCIR-
656. In this mode, video data is multiplexed in the same fashion in CCIR-656, but the values 0 and 255 are not reserved as signaling values. Instead, external HSYNC and VSYNC pins are used for signaling and video synchronization. VCLK may range up to
29.5 MHz.

Host Interface
The ADV601LC host interface is a high performance interface that passes all command and real-time compressed video data between the host and codec. A 512 position by 32-bit wide, bidirectional FIFO buffer passes compressed video data to and from the host. The host interface is capable of burst transfer rates of up to 132 million bytes per second (4 × 33 MHz). For host interface pins descriptions, see the Pin Function Descriptions section. For host interface timing information, see the Host Interface Timing section.
DRAM Manager
The DRAM Manager provides a sorting and reordering func­tion on the sub-band coded data between the Wavelet Kernel and the Programmable Quantizer. The DRAM manager pro­vides a pipeline delay stage to the ADV601LC. This pipeline lets the ADV601LC extract current field image statistics (min/ max pixel values, sum of pixel values, and sum of squares) used
VCLK is driven with up to a 29.5 MHz 50% duty cycle clock synchronous with the video data. Video data is clocked on the rising edge of the VCLK signal.

in the calculation of Bin Widths and re-order wavelet transform data. The use of current field statistics in the Bin Width calcu­lation results in precise control over the compressed bit rate. The DRAM manager manages the entire operation and refresh of the DRAM.
The interface between the ADV601LC DRAM manager and DRAM is designed to be transparent to the user. The ADV601LC DRAM pins should be connected to the DRAM as called out in the Pin Function Descriptions section. The ADV601LC re­quires one 256K word by 16-bit, 60 ns DRAM. The following is a selected list of manufacturers and part numbers. All parts can be used with the ADV601LC at all VCLK rates except where noted. Any DRAM used with the ADV601LC must meet the minimum specifications outlined for the Hyper Mode DRAMs listed in Table XI. For DRAM Interface pins descrip­tions, see the Pin Function Descriptions.

<BW> (16 bits, 8.8) This data code is not entropy coded, is always 16 bits in length and defines the Bin
Width Quantizer control used on all data in the block sub-band. During decode, this value is used by the Quantizer. If this value is set to zero during decode, all Huffman data is presumed to be zero and is ignored, but must be included. During encode, this value is calculated by the external Host and is inserted into the bit stream by the ADV601LC (this value is not used by the quantizer). Another value calculated by the Host, 1/BW is actually used by the Quantizer during encode.
<HUFF_DATA> (Modulo 32) This data is the quantized and entropy coded block sub-band data. The data’s length is
dependent on block size and entropy coding so it is therefore variable in length. This field is filled with 1s making it Modulo 32 bits in length. Any Huffman decode process can be interrupted and reset by any unexpectedly received # delimiter following a bit error or synchronization problem.
#EOS 0xffffffffc0ffffff The host sends the #EOS (End of Sequence) to the ADV601LC during decode after
the last field in a sequence to indicate that the field sequence is complete. The ADV601LC does not append this code to the end of encoded field sequences; it must be added by the host.

Raytheon has a whole family of video parts. Any member of the family can be used. The user must select the part needed based on the requirements of the application. Because the Raytheon part does not include the A/Ds, an external A/D is necessary in this design (or a pair of A/Ds for S video).
The part can be used in CCIR-656 (D1) mode for a zero con­trol signal interface. Special attention must be paid to the video output modes in order to get the right data to the right pins (see the following diagram).
Note that the circuit in Figure 17 has not been built or tested.
Using the Analog Devices ADV7175 Video Encoder
Because the ADV7175 has a CCIR-656 interface, it connects directly with the ADV601LC without “glue” logic. Note that the ADV7175 can only be used at CCIR-601 sampling rates.
The ADV7175 example circuit, which appears in Figure 16, is used in this configuration on the ADV601LC Video Lab dem­onstration board.

GETTING THE MOST OUT OF ADV601LC

The unique sub-band block structure of luminance and color components in the ADV601LC offers many unique application benefits. Analog Devices will offer a Feature Software Library as well as separate feature application documentation to help users exploit these features. The following section provides an over­view of only some of the features and how they are achieved with the ADV601LC. Please refer to Figures 2 and 3 as necessary.
Higher Compression With Interfield Techniques
The ADV601LC normally operates as a field-independent codec. However, through use of the sub-bands it is possible to use the ADV601LC with interfield techniques to achieve even higher levels of compression. In such applications, each field is not compressed separately, thus accessing the compressed bit stream can only be done at specific points in time. There are two general ways this can be accomplished:
• Subsampling high frequency blocks
The human visual system is more sensitive to interframe motion of low frequency block than to motion in high fre­quency blocks. The host software driver of the ADV601LC allows exploitation of this option to achieve higher com­pression. Note that the compressed bit stream can only be accessed at points where the high frequency blocks have just been updated.
• Updating the image with motion detection
In applications where the video is likely to have no motion for extended periods of time (video surveillance in a vacant build­ing, for instance), it is only necessary to update the image either periodically or when motion occurs. By using the wave­let sub-bands to detect motion (see later in this section), it is possible to achieve very high levels of compression when motion is infrequent.
Scalable Compression Technology
The ADV601LC offers many different options for scaling the image, the compressed bit stream bandwidth and the processing horsepower for encode or decode. Because the ADV601LC employs decimators, interpolators and filters in the filter bank, the scaling function creates much higher quality images than achieved through pixel dropping. Mixing and matching the many scaling options is useful in network applications where transmission pipes may vary in available bit rate, and decode/ encode capabilities may be a mix of software and hardware. These are the key options:
• Extract scaled images by factors of 2 from the compressed bit stream
This is useful in video editing applications where thumbnail sketches of fields need to be displayed. In this case, editing software can quickly extract and decode the desired image. This technique eliminates the burden of decoding an entire image and then scaling to the desired size.
• Use software to decode bit stream
Decoding an entire CCIR-601 resolution image in real time at 50/60 fields per second does require the ADV601LC hard­ware. Analog Devices provides a bit-exact ADV601LC simulator that can decode a scaled image in real time or a full­size image off-line. Image size and frame rates depend on the performance of the host processor.
• Scale bit stream
The compressed video bit stream was created with simple parsing in mind. This type of parsing means that a lower resolution/lower bandwidth bit stream can be extracted with little computational burden. Generally, this effect is accom­plished by selecting a subset of lower frequency blocks. This technique is useful in applications where the same video source material must be sent over a range of different commu­nication pipes {i.e., ISDN (128 Kbps), T1 (1.5 Mbps) or T3 (45 Mbps)}.
• Use software to encode
In this case, a host CPU could encode a smaller image size and fill in high frequency blocks with zeros. Again, image quality would depend on the performance of the host. The Bin Width may be set to zero, zeroing out the data in any particular Mallat block.
Parametric Image Filtering
The ADV601LC offers a unique set of image filtering capa­bilities not found in other compression technologies. The ADV601LC quantizer is capable of attenuating any or all of the luminance or chrominance blocks during encode or decode. Here are some of the possible applications:
• Parametric softening of color saturation and contrast during encode or decode
Trade off image softness for higher compression. Attenua­tion of the higher frequency blocks during encode leads to softer images, but it can lead to much higher compression performance.
• Color saturation control
This effect is achieved by controlling gain of low pass chromi­nance blocks during encode or decode.
• Contrast control
This effect is achieved by controlling the gain of the low fre­quency luminance blocks during encode or decode.
• Fade to black
This effect achieved by attenuation of luminance blocks.
Mixing of Two or More Images
Blocks from different images can be mixed into the bit stream and then sent to the ADV601LC during decode. The result is high quality mixing of different images. This also provides the capability to fade from one image to the next.
Edge or Motion Detection
In certain remote video surveillance and machine vision applica­tions, it is desirable to detect edges or motion. Edges can be quickly found through evaluation of the high frequency blocks. Motion searches can be achieved in two ways:
• Evaluation of the smallest luminance block. Because the size of the smallest block is so mcuh smaller than the others, the computational burden is significantly less than doing an evaluation over the entire image.
• Polling the Sum of Squares registers. Because large changes in the video data create patterns, it is possible to detect motion in the video by polling the Sum of Squares registers, looking for patterns and changes.

Host Interface (Indirect Address, Indirect Register Data, and Interrupt Mask/Status) Register Timing
The diagrams in this section show transfer timing for host read and write accesses to all of the ADV601LC’s direct registers, except the Compressed Data register. Accesses to the Indirect Address, Indirect Register Data, and Interrupt Mask/Status registers are slower than access timing for the Compressed Data register. For information on access timing for the Compressed Data direct regis­ter, see the Host Interface (Compressed Data) Register Timing section. Note that for accesses to the Indirect Address, Indirect Reg­ister Data and Interrupt Mask/Status registers, your system MUST observe ACK and RD or WR assertion timing.

Host Interface (Compressed Data) Register Timing
The diagrams in this section show transfer timing for host read and write transfers to the ADV601LC’s Compressed Data register. Accesses to the Compressed Data register are faster than access timing for the Indirect Address, Indirect Register Data, and Interrupt Mask/Status registers. For information on access timing for the other registers, see the Host Interface (Indirect Address, Indirect Register Data, and Interrupt Mask/Status) Register Timing section. Also note that as long as your system observes the RD or WR signal assertion timing, your system does NOT have to wait for the ACK signal between new compressed data addresses.
