1 Introduction

Macrovision is a trademark of Macrovision Corporation. O

The TVP5150A device is an ultralow power NTSC/PAL/SECAM video decoder. Available in a space saving 32-pin TQFP package, the TVP5150A decoder converts NTSC, PAL, and SECAM video signals to 8-bit ITU-R BT.656 format. Discrete syncs are also available. The optimized architecture of the TVP5150A decoder allows for ultralow-power consumption. The decoder consumes 115 mW of power in typical operation and consumes less than 1 mW in power-down mode, considerably increasing battery life in portable applications. The decoder uses just one crystal for all supported standards. The TVP5150A decoder can be programmed using an I decoder uses a 1.8-V supply for its analog and digital supplies, and a 3.3-V supply for its I/O.

The TVP5150A decoder converts baseband analog video into digital YCbCr 4:2:2 component video. Composite and S-video inputs are supported. The TVP5150A decoder includes one 9-bit analog-to-digital converter (ADC) with 2x sampling. Sampling is ITU-R BT.601 (27.0 MHz, generated from the 14.31818-MHz crystal or oscillator input) and is line-locked. The output formats can be 8-bit 4:2:2 or 8-bit ITU-R BT.656 with embedded synchronization.

The TVP5150A decoder utilizes Texas Instruments patented technology for locking to weak, noisy, or unstable signals. A Genlock/real-time control (RTC) output is generated for synchronizing downstream video encoders.

Complementary 4-line adaptive comb filtering is available for both the luma and chroma data paths to reduce both cross-luma and cross-chroma artifacts; a chroma trap filter is also available.

C serial interface. The

Video characteristics including hue, contrast, brightness, saturation, and sharpness may be programmed using the industry standard I

C serial interface. The TVP5150A decoder generates synchronization, blanking, lock, and clock

signals in addition to digital video outputs. The TVP5150A decoder includes methods for advanced vertical blanking interval (VBI) data retrieval. The VBI data processor slices, parses, and performs error checking on teletext, closed caption, and other data in several formats.

The TVP5150A decoder detects copy-protected input signals according to the Macrovision standard and detects Type 1, 2, 3, and colorstripe pulses.

2 Functional Description

2.1 Analog Front End

The TVP5150A decoder has an analog input channel that accepts two video inputs, which are ac-coupled. The decoder supports a maximum input voltage range of 0.75 V; therefore, an attenuation of one-half is needed for most input signals with a peak-to-peak variation of 1.5 V. The maximum parallel termination before the input to the device is 75 Ω. Please refer to the applications diagram in Figure 5−1 for the recommended configuration. The two analog input ports can be connected as follows:

• Two selectable composite video inputs or

• One S-video input

An internal clamping circuit restores the ac-coupled video signal to a fixed dc level. The programmable gain amplifier (PGA) and the AGC circuit work together to make sure that the input signal is

amplified sufficiently to ensure the proper input range for the ADC. The ADC has 9 bits of resolution and runs at a maximum speed of 27 MHz. The clock input for the ADC comes from

the PLL.

2.2 Composite Processing Block Diagram

The composite processing block processes NTSC/PAL/SECAM signals into the YCbCr color space. Figure 2−1 explains the basic architecture of this processing block.

Figure 2−1 illustrates the luminance/chrominance (Y/C) separation process in the TVP5150A decoder. The composite video is multiplied by subcarrier signals in the quadrature modulator to generate the color difference signals Cb and Cr . Cb and Cr are then low-pass (LP) filtered to achieve the desired bandwidth and to reduce crosstalk.

An adaptive 4-line comb filter separates CbCr from Y. Chroma is remodulated through another quadrature modulator and subtracted from the line-delayed composite video to generate luma. Contrast, brightness, hue, saturation, and sharpness (using the peaking filter) are programmable via I

The Y/C separation is bypassed for S-video input. For S-video, the remodulation path is disabled.

2.3 Adaptive Comb Filtering

The 4-line comb filter can be selectively bypassed in the luma or chroma path. If the comb filter is bypassed in the luma path, then chroma notch filters are used. TI’s patented adaptive 4-line comb filter algorithm reduces artifacts such as hanging dots at color boundaries and detects and properly handles false colors in high frequency luminance images such as a multiburst pattern or circle pattern.

2.4 Color Low-Pass Filter

In some applications, it is desirable to limit the Cb/Cr bandwidth to avoid crosstalk. This is especially true in case of video signals that have asymmetrical Cb/Cr sidebands. The color LP filters provided limit the bandwidth of the Cb/Cr signals.

Color LP filters are needed when the comb filtering turns off, due to extreme color transitions in the input image. Please refer to Sec t ion 2.20.25, Chrominance Control #2 Register, for the response of these filters. The filters have three options that allow three different frequency responses based on the color frequency characteristics of the input video.

2.5 Luminance Processing

The luma component is derived from the composite signal by subtracting the remodulated chroma information. A line delay exists in this path to compensate for the line delay in the adaptive comb filter in the color processing chain. The luma information is then fed into the peaking circuit, which enhances the high frequency components of the signal, thus improving sharpness.

2.6 Chrominance Processing

For NTSC/PAL formats, the color processing begins with a quadrature demodulator. The Cb/Cr signals then pass through the gain control stage for chroma saturation adjustment. An adaptive comb filter is applied to the demodulated signals to separate chrominance and eliminate cross-chrominance artifacts. An automatic color killer circuit is also included in this block. The color killer suppresses the chroma processing when the color burst of the video signal is weak or not present. The SECAM standard is similar to PAL except for the modulation of color which is FM instead of QAM.

2−2

2.7 Timing Processor

The timing processor is a combination of hardware and software running in the internal microprocessor that serves to control horizontal lock to the input sync pulse edge, AGC and offset adjustment in the analog front end, vertical sync detection, and Macrovisiont detection.

2.8 VBI Data Processor

The TVP5150A VBI data processor (VDP) slices various data services like teletext (WST, NABTS), closed caption (CC), wide screen signaling (WSS), etc. These services are acquired by programming the VDP to enable standards in the VBI. The results are stored in a FIFO and/or registers. The teletext results are stored in a FIFO only. Table 2−1 lists a summary of the types of VBI data supported according to the video standard. It supports ITU-R BT. 601 sampling for each.

lookup table (see Section 2.20.58). This is done through port address C3h. Each read from or write to this address will auto increment an internal counter to the next RAM location. To access the VDP-CRAM, the line mode registers (D0h−FCh) must be programmed with FFh to avoid a conflict with the internal microprocessor and the VDP in both writing and reading. Full field mode must also be disabled.

Available VBI lines are from line 6 to line 27 of both field 1 and field 2. Each line can be any VBI mode. Output data is available either through the VBI-FIFO (B0h) or through dedicated registers at 90h−AFh, both of which

are available through the I

C port.

2.9 VBI FIFO and Ancillary Data in Video Stream

Sliced VBI data can be output as ancillary data in the video stream in the ITU-R BT.656 mode. VBI data is output during the horizontal blanking period following the line from which the data was retrieved. Table 2−2 shows the header format and sequence of the ancillary data inserted into the video stream. This format is also used to store any VBI data into the FIFO. The size of FIFO is 512 bytes. Therefore, the FIFO can store up to 11 lines of teletext data with the NTSC NABTS standard.

2.13 AVID Cropping

AVID or active video cropping provides a means to decrease bandwidth of the video output. This is accomplished by horizontally blanking a number of AVID pulses and by vertically blanking a number of lines per frame. The horizontal AVID cropping is controlled using registers 11h and 12h for start pixels MSB and LSB, respectively.

Registers 13h and 14h provide access to stop pixels MSB and LSB, respectively. The vertical AVID cropping is controlled using the vertical blanking (VBLK) start and stop registers at addresses 18h and 19h. Figure 2−4 shows an AVID application.

2.14 Embedded Syncs

Standards with embedded syncs insert SAV and EAV codes into the datastream at the beginning and end of horizontal blanking. These codes contain the V and F bits which also define vertical timing. F and V change on EAV . Table 2−4 gives the format of the SAV and EAV codes.

H equals 1 always indicates EAV. H equals 0 always indicates SAV. The alignment of V and F to the line and field counter varies depending on the standard. Please refer to ITU-R BT.656 for more information on embedded syncs.

The P bits are protection bits:

P3 = V xor H P2 = F xor H P1 = F xor V P0 = F xor V xor H

2.15 I2C Host Interface

The I2C standard consists of two signals, serial input/output data line (SDA) and input/output clock line (SCL), which carry information between the devices connected to the bus. A third signal (I2CSEL) is used for slave address selection. Although the I

Both SDA and SCL must be connected to a positive supply voltage via a pullup resistor. When the bus is free, both lines are high. The slave address select terminal (I2CSEL) enables the use of two TVP5150A decoders tied to the

same I

C bus. At power up, the status of the I2CSEL is polled. Depending on the write and read addresses to be used for the TVP5150A decoder, it can either be pulled low or high through a resistor. This terminal is multiplexed with YOUT7 and hence must not be tied directly to ground or IO_DVDD. Table 2−6 summarizes the terminal functions of

the I

C-mode host interface.

Data transfer rate on the bus is up to 400 kbits/s. The number of interfaces connected to the bus is dependent on the bus capacitance limit of 400 pF. The data on the SDA line must be stable during the high period of the SCL except for start and stop conditions. The high or low state of the data line can only change with the clock signal on the SCL line being low. A high-to-low transition on the SDA line while the SCL is high indicates an I low-to-high transition on the SDA line while the SCL is high indicates an I

C system can be multimastered, the TVP5150A decoder functions as a slave device only.

Every byte placed on the SDA must be 8 bits long. The number of bytes which can be transferred is unrestricted. Each byte must be followed by an acknowledge bit. The acknowledge-related clock pulse is generated by the I

2.15.1 I2C Write Operation

Data transfers occur utilizing the following illustrated formats.

C master initiates a write operation to the TVP5150A decoder by generating a start condition (S) followed by

An I the TVP5150A I receiving an acknowledge from the TVP5150A decoder, the master presents the subaddress of the register, or the first of a block of registers it wants to write, followed by one or more bytes of data, MSB first. The TVP5150A decoder acknowledges each byte after completion of each transfer. The I generating a stop condition (P).

2.15.2 I2C Read Operation

The read operation consists of two phases. The first phase is the address phase. In this phase, an I2C master initiates a write operation to the TVP5150A decoder by generating a start condition (S) followed by the TVP5150A I

C address, in MSB first bit order, followed by a 0 to indicate a write cycle. After receiving acknowledges from the TVP5150A decoder, the master presents the subaddress of the register or the first of a block of registers it wants to read. After the cycle is acknowledged, the master terminates the cycle immediately by generating a stop condition (P).

Table 2−7. Read Address Selection

The second phase is the data phase. In this phase, an I2C master initiates a read operation to the TVP5150A decoder by generating a start condition followed by the TVP5150A I first bit order, followed by a 1 to indicate a read cycle. After an acknowledge from the TVP5150A decoder, the I master receives one or more bytes of data from the TVP5150A decoder. The I

C master acknowledges the transfer

at the end of each byte. After the last data byte desired has been transferred from the TVP5150A decoder to the master, the master generates a not acknowledge followed by a stop.

2.15.2.3I2C Timing Requirements

The TVP5150A decoder requires delays in the I2C accesses to accommodate its internal processor’s timing. In accordance with I period to the I

C specifications, the TVP5150A decoder holds the I2C clock line (SCL) low to indicate the wait

C master. If the I2C master is not designed to check for the I2C clock line held-low condition, then the maximum delays must always be inserted where required. These delays are of variable length; maximum delays are indicated in the following diagram:

The 64-µs delay is for all registers that do not require a reinitialization. Delays may be more for some registers.

2.16 Clock Circuits

An internal line-locked PLL generates the system and pixel clocks. A 14.31818-MHz clock is required to drive the PLL. This may be input to the TVP5150A decoder on terminal 5 (XTAL1), or a crystal of 14.31818-MHz fundamental resonant frequency may be connected across terminals 5 and 6 (XTAL2). Figure 2−5 shows the reference clock configurations.

2.17 Genlock Control and RTC

A Genlock control (GLCO) function is provided to support a standard video encoder to synchronize its internal color oscillator for properly reproduced color with unstable timebase sources like VCRs.

The frequency control word of the internal color subcarrier digital control oscillator (DTO) and the subcarrier phase reset bit are transmitted via terminal 23 (GLCO). The frequency control word is a 23-bit binary number . The frequency of the DTO can be calculated from the following equation:

ctrl

dto

sclk

where F SCLK.

is the frequency of the DTO, F

dto

is the 23-bit DTO frequency control, and F

ctrl

is the frequency of the

sclk

2.17.1 TVP5150A Genlock Control Interface

A write of 1 to bit 4 of the chrominance control register at I2C subaddress 1Ah causes the subcarrier DTO phase reset bit to be sent on the next scan line on GLCO. The active low reset bit occurs 7 SCLKs after the transmission of the last bit of DCO frequency control. Upon the transmission of the reset bit, the phase of the TVP5150A internal subcarrier DCO is reset to zero.

A Genlock slave device can be connected to the GLCO terminal and uses the information on GLCO to synchronize its internal color phase DCO to achieve clean line and color lock.

Interrupt enable register B is used by the external processor to mask unnecessary interrupt sources for interrupt B. Bits loaded with a 1 allow the corresponding interrupt condition to generate an interrupt on the external pin. Conversely, bits loaded with 0s mask the corresponding interrupt condition from generating an interrupt on the external pin. This register only affects the external pin, it does not affect the bits in the interrupt status register. A given condition can set the appropriate bit in the status register and not cause an interrupt on the external pin. To determine if this device is driving the interrupt pin either AND interrupt status register B with interrupt enable register B or check the state of interrupt B in the interrupt B active register.

FIFO read data

This address is provided to access VBI data in the FIFO through the host port. All forms of teletext data come directly from the FIFO, while all other forms of VBI data can be programmed to come from the registers or from the FIFO. Current status of the FIFO can be found at address C6h and the number of bytes in the FIFO is located at address C7h. If the host port is to be used to read data from the FIFO, then the output formatter must be disabled at address CDh bit 0. The format used for the VBI FIFO is shown in Section 2.9.

For an NABTS system, the packet prefix consists of five bytes. Each byte contains four data bits (D[3:0]) interlaced

with four Hamming protection bits (H[3:0]):

Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0

D[3] H[3] D[2] H[2] D[1] H[1] D[0] H[0]

Only the data portion D[3:0] from each byte is applied to a teletext filter function with the corresponding pattern bits

P[3:0] and mask bits M[3:0]. Hamming protection bits are ignored by the filter.

For a WST system (PAL or NTSC), the packet prefix consists of two bytes so that two patterns are used. Patterns

3, 4, and 5 are ignored.

The mask bits enable filtering using the corresponding bit in the pattern register. For example, a 1 in the LSB of mask 1

means that the filter module must compare the LSB of nibble 1 in the pattern register to the first data bit on the

transaction. If these match, then a true result is returned. A 0 in a bit of mask 1 means that the filter module must ignore

that data bit of the transaction. If all 0s are programmed in the mask bits, then the filter matches all patterns returning

a true result (default 00h).

Pattern and mask for each byte and filter are referred as <1,2><P,M><1,2,3,4,5> where:

<1,2> identifies the filter 1 or 2 <P,M> identifies the pattern or mask <1,2,3,4,5> identifies the byte number

Lock state interrupt:

0 = TVP5150A is not locked to the video signal (default). 1 = TVP5150A is locked to the video signal.

Lock interrupt:

0 = A transition has not occurred on the lock signal (default). 1 = A transition has occurred on the lock signal.

FIFO threshold interrupt:

0 = The amount of data in the FIFO has not yet crossed the threshold programmed at address C8h (default). 1 = The amount of data in the FIFO has crossed the threshold programmed at address C8h.

Line interrupt:

0 = The video line number has not yet been reached (default). 1 = The video line number programmed in address CAh has occurred.

Lock interrupt

enable

The interrupt enable register A is used by the host processor to mask unnecessary interrupt sources. Bits loaded with a 1 allow the corresponding interrupt condition to generate an interrupt on the external pin. Conversely, bits loaded with a 0 mask the corresponding interrupt condition from generating an interrupt on the external pin. This register only affects the interrupt on the external terminal, it does not affect the bits in interrupt status register A. A given condition can set the appropriate bit in the status register and not cause an interrupt on the external terminal. To determine if this device is driving the interrupt terminal either perform a logical AND of interrupt status register A with interrupt enable register A, or check the state of the interrupt A bit in the interrupt configuration register at address C2h.

Interrupt polarity A:

0 = Interrupt A is active low (default). 1 = Interrupt A is active high.

Interrupt configuration register A is used to configure the polarity of the external interrupt terminal. When interrupt

A is configured as active low, the terminal is driven low when active and high-impedance when inactive (open

collector). Conversely, when the terminal is configured as active high, it is driven high when active and driven low

when inactive.

C5h Reserved

The configuration RAM data is provided to initialize the VDP with initial constants. The configuration RAM is 512 bytes

organized as 32 dif ferent configurations of 16 bytes each. The first 12 configurations are defined for the current VBI

standards. An additional 2 configurations can be used as a custom programmed mode for unique standards like

Gemstar.

Address C3h is used to read or write to the RAM. The RAM internal address counter is automatically incremented

with each transaction. Addresses C5h and C4h make up a 9-bit address to load the internal address counter with a

specific start address. This can be used to write a subset of the RAM for only those standards of interest. Registers

D0h−FBh must all be programmed with FFh, before writing or reading the configuration RAM. Full field mode (CFh)

must be disabled as well.

Address C6h

7 6 5 4 3 2 1 0

FIFO full error FIFO empty TTX available CC field 1 available CC field 2 available WSS available VPS available VITC available

The VDP status register indicates whether data is available in either the FIFO or data registers, and status information

about the FIFO. Reading data from the corresponding register does not clear the status flags automatically. These

flags are only reset by writing a 1 to the respective bit. However, bit 6 is updated automatically.

FIFO full error:

0 = No FIFO full error 1 = FIFO was full during a write to FIFO.

The FIFO full error flag is set when the current line of VBI data can not enter the FIFO. For example, if the FIFO has

only 10 bytes left and teletext is the current VBI line, the FIFO full error flag is set, but no data is written because the

entire teletext line will not fit. However, if the next VBI line is closed caption requiring only 2 bytes of data plus the

header, this goes into the FIFO. Even if the full error flag is set.

FIFO empty:

0 = FIFO is not empty. 1 = FIFO is empty.

TTX available:

0 = Teletext data is not available. 1 = Teletext data is available.

CC field 1 available:

0 = Closed caption data from field 1 is not available. 1 = Closed caption data from field 1 is available.

CC field 2 available:

0 = Closed caption data from field 2 is not available. 1 = Closed caption data from field 2 is available.

WSS available:

0 = WSS data is not available. 1 = WSS data is available.

VPS available:

0 = VPS data is not available. 1 = VPS data is available.

VITC available:

0 = VITC data is not available. 1 = VITC data is available.

These registers form a 10-bit horizontal pixel position from the falling edge of sync, where the VDP controller initiates the program from one line standard to the next line standard; for example, the previous line of teletext to the next line of closed caption. This value must be set so that the switch occurs after the previous transaction has cleared the delay in the VDP, but early enough to allow the new values to be programmed before the current settings are required.

NOTE: The use of INTERQ/GPCL/AVID/HSYNC and VSYNC is optional. These are outputs and can be left floating.

When OSC is connected through S1, remove the capacitors for the crystal. PDN needs to be high, if device has to be always operational. RESETB is operational only when PDN is high. This allows an active low reset to the device.
