SLES140F–JULY 2005–REVISED DECEMBER 2010

1.2 Description

The TVP5147M1 device is a high-quality, single-chip digital video decoder that digitizes and decodes all popular baseband analog video formats into digital component video. The TVP5147M1 decoder supports the analog-to-digital (A/D) conversion of component YPbPr signals, as well as the A/D conversion and decoding of NTSC, PAL, and SECAM composite and S-video into component YCbCr. This decoder includes two 11-bit 30-MSPS A/D converters (ADCs). Preceding each ADC in the device, the corresponding analog channel contains an analog circuit that clamps the input to a reference voltage and applies a programmable gain and offset. A total of ten video input terminals can be configured to a combination of YPbPr, CVBS, or S-video video inputs.

Composite or S-video signals are sampled at 2× the ITU-R BT.601 clock frequency, line-locked alignment, and are then decimated to the 1× pixel rate. CVBS decoding uses five-line adaptive comb filtering for both the luma and chroma data paths to reduce both cross-luma and cross-chroma artifacts. A chroma trap filter is also available. On CVBS and S-video inputs, the user can control video characteristics such as contrast, brightness, saturation, and hue via an I2C host port interface. Furthermore, luma peaking (sharpness) with programmable gain is included, as well as a patented chroma transient improvement (CTI) circuit.

The following output formats can be selected: 20-bit 4:2:2 YCbCr or 10-bit 4:2:2 YCbCr. The TVP5147M1 decoder generates synchronization, blanking, field, active video window, horizontal and

vertical syncs, clock, genlock (for downstream video encoder synchronization), host CPU interrupt and programmable logic I/O signals, in addition to digital video outputs.

www.ti.com

The TVP5147M1 decoder includes methods for advanced vertical blanking interval (VBI) data retrieval. The VBI data processor (VDP) slices, parses, and performs error checking on teletext, closed caption (CC), and other VBI data. A built-in FIFO stores up to 11 lines of teletext data, and with proper host port synchronization, full-screen teletext retrieval is possible. The TVP5147M1 decoder can pass through the output formatter 2× sampled raw luma data for host-based VBI processing.

The main blocks of the TVP5147M1 decoder include:

• Robust sync detection for weak and noisy signals as well as VCR trick modes

• Y/C separation by 2-D 5-line adaptive comb or chroma trap filter

• Two 11-bit, 30-MSPS A/D converters with analog preprocessors [clamp and automatic gain control (AGC)]

• Analog video output

• Luminance processor

• Chrominance processor

• Clock/timing processor and power-down control

• Software-controlled power-saving standby mode

• Output formatter

• I2C host port interface

• VBI data processor

• Macrovision™ copy protection detection circuit (Type 1, 2, 3, and separate color stripe detection)

• 3.3-V tolerant digital I/O ports

2 Functional Description

2.1 Analog Processing and A/D Converters

Figure 2-1 shows a functional diagram of the analog processors and A/D converters, which provide the

analog interface to all video inputs. It accepts up to ten inputs and performs source selection, video clamping, video amplification, A/D conversion, and gain and offset adjustments to center the digitized video signal. The TVP5147M1 supports one analog video output for the selected analog input video.

2.1.1 Video Input Switch Control

The TVP5147M1 decoder has two analog channels that accept up to ten video inputs. The user can configure the internal analog video switches via the I2C interface. The ten analog video inputs can be used for different input configurations, some of which are:

• Up to ten selectable individual composite video inputs

• Up to four selectable S-video inputs

• Up to three selectable analog YPbPr video inputs and one CVBS input

• Up to two selectable analog YPbPr video inputs, one S-video input, and two CVBS inputs The input selection is performed by the input select register at I2C subaddress 00h (see Table 2-12).

2.1.2 Analog Input Clamping

An internal clamping circuit restores the ac-coupled video signal to a fixed dc level. The clamping circuit provides line-by-line restoration of the video sync level to a fixed dc reference voltage. The selection between bottom and mid clamp is performed automatically by the TVP5147M1 decoder.

2.1.3 Automatic Gain Control

The TVP5147M1 decoder uses two programmable gain amplifiers (PGAs), one per channel. The PGA can scale a signal with a voltage-input compliance of 0.5-VPP to 2.0-VPP to a full-scale 10-bit A/D output code range. A 4-bit code sets the coarse gain with individual adjustment per channel. Minimum gain corresponds to a code 0x0 (2.0-VPP full-scale input, -6-dB gain) while maximum gain corresponds to code 0xF (0.5 VPP full scale, +6-dB gain). The TVP5147M1 decoder also has 12-bit fine gain controls for each channel and applies independently to coarse gain controls. For composite video, the input video signal amplitude can vary significantly from the nominal level of 1 VPP. The TVP5147M1 decoder can adjust its PGA setting automatically: an automatic gain control (AGC) can be enabled and can adjust the signal amplitude such that the maximum range of the ADC is reached without clipping. Some nonstandard video signals contain peak white levels that saturate the ADC. In these cases, the AGC automatically cuts back gain to avoid clipping. If the AGC is on, then the TVP5147M1 decoder can read the gain currently being used.

SLES140F–JULY 2005–REVISED DECEMBER 2010

The TVP5147M1 AGC comprises the front-end AGC before Y/C separation and the back-end AGC after Y/C separation. The back-end AGC restores the optimum system gain whenever an amplitude reference such as the composite peak (which is only relevant before Y/C separation) forces the front-end AGC to set the gain too low. The front-end and back-end AGC algorithms can use up to four amplitude references: sync height, color burst amplitude, composite peak, and luma peak.

The specific amplitude references being used by the front-end and back-end AGC algorithms can be independently controlled using the AGC white peak processing register located at subaddress 74h. The TVP5147M1 gain increment speed and gain increment delay can be controlled using the AGC increment speed register located at subaddress 78h and the AGC increment delay register located at subaddress 79h.

2.1.4 Analog Video Output

One of the analog input signals is available at the analog video output terminal, which is shared with input selected by I2C registers. The signal at this terminal must be buffered by a source follower. The nominal output voltage is 2 V p-p, thus the signal can be used to drive a 75-Ω line. The magnitude is maintained with an AGC in 16 steps controlled by the TVP5147M1 decoder. To use this function, terminal VI_1_A must be set as an output terminal. The input mode selection register also selects an active analog output signal.

2.1.5 A/D Converters

All ADCs have a resolution of 11 bits and can operate up to 30 MSPS. All A/D channels receive an identical clock from the on-chip phase-locked loop (PLL) at a frequency between 24 MHz and 30 MHz. All ADC reference voltages are generated internally.

2.2 Digital Video Processing

Figure 2-2 is a block diagram of the TVP5147M1 digital video decoder processing. This block receives

digitized video signals from the ADCs and performs composite processing for CVBS and S-video inputs and YCbCr signal enhancements for CVBS and S-video inputs. It also generates horizontal and vertical syncs and other output control signals such as genlock for CVBS and S-video inputs. Additionally, it can provide field identification, horizontal and vertical lock, vertical blanking, and active video window indication signals. The digital data output can be programmed to two formats: 20-bit 4:2:2 with external syncs or 10-bit 4:2:2 with embedded/separate syncs. The circuit detects pseudosync pulses, AGC pulses, and color striping in Macrovision-encoded copy-protected material. Information present in the VBI interval can be retrieved and either inserted in the ITU-R BT.656 output as ancillary data or stored in internal FIFO and/or registers for retrieval via the host port interface.

2.2.1 2x Decimation Filter

All input signals are typically oversampled by a factor of 2 (27 MHz). The A/D outputs initially pass through decimation filters that reduce the data rate to 1× the pixel rate. The decimation filter is a half-band filter. Oversampling and decimation filtering can effectively increase the overall signal-to-noise ratio by 3 dB.

2.2.2 Composite Processor

Figure 2-3 is a block diagram of the TVP5147M1 digital composite video processing circuit. This

processing circuit receives a digitized composite or S-video signal from the ADCs and performs Y/C separation (bypassed for S-video input), chroma demodulation for PAL/NTSC and SECAM, and YUV signal enhancements.

The 10-bit composite video is multiplied by the subcarrier signals in the quadrature demodulator to generate color difference signals U and V. The U and V signals are then sent to low-pass filters to achieve the desired bandwidth. An adaptive 5-line comb filter separates UV from Y based on the unique property of color phase shifts from line to line. The chroma is remodulated through a quadrature modulator and subtracted from line-delayed composite video to generate luma. This form of Y/C separation is completely complementary, thus there is no loss of information. However, in some applications, it is desirable to limit the U/V bandwidth to avoid crosstalk. In that case, notch filters can be turned on. To accommodate some viewing preferences, a peaking filter is also available in the luma path. Contrast, brightness, sharpness, hue, and saturation controls are programmable through the host port.

2.2.2.1 Color Low-Pass Filter

High filter bandwidth preserves sharp color transitions and produces crisp color boundaries. However, for nonstandard video sources that have asymmetrical U and V side bands, it is desirable to limit the filter bandwidth to avoid UV crosstalk. The color low-pass filter bandwidth is programmable to enable one of the three notch filters. Figure 2-4 and Figure 2-5 represent the frequency responses of the wideband color low-pass filters.

2.2.2.2 Y/C Separation

Y/C separation can be done using adaptive 5-line (5-H delay) comb filters or a chroma trap filter. The comb filter can be selectively bypassed in the luma or chroma path. If the comb filter is bypassed in the luma path, then chroma trap filters are used which are shown in Figure 2-6 and Figure 2-7. The TI patented adaptive comb filter algorithm reduces artifacts such as hanging dots at color boundaries. It detects and properly handles false colors in high-frequency luminance images such as a multiburst pattern or circle pattern.

2.2.3 Luminance Processing

The digitized composite video signal passes through either a luminance comb filter or a chroma trap filter, either of which removes chrominance information from the composite signal to generate a luminance signal. The luminance signal is then fed into the input of a peaking circuit. Figure 2-8 illustrates the basic functions of the luminance data path. In the case of S-video, the luminance signal bypasses the comb filter or chroma trap filter and is fed directly to the circuit. A peaking filter (edge enhancer) amplifies high-frequency components of the luminance signal. Figure 2-9 shows the characteristics of the peaking filter at four different gain settings that are user-programmable via the I2C interface.

2.2.4 Color Transient Improvement

Color transient improvement (CTI) enhances horizontal color transients. The color difference signal transition points are maintained, but the edges are enhanced for signals that have bandwidth-limited color components.

2.3 Clock Circuits

An internal line-locked PLL generates the system and pixel clocks. A 14.318-MHz clock is required to drive the PLL. This can be input to the TVP5147M1 decoder at the 1.8-V level on terminal 74 (XTAL1), or a crystal of 14.318-MHz fundamental resonant frequency can be connected across terminals 74 and 75 (XTAL2). If a parallel resonant circuit is used as shown in Figure 2-10, then the external capacitors must have the following relationship:

CL1= CL2= 2CL − C

2.4 Real-Time Control (RTC)

Although the TVP5147M1 decoder is a line-locked system, the color burst information is used to determine accurately the color subcarrier frequency and phase. This ensures proper operation with nonstandard video signals that do not follow exactly the required frequency multiple between color subcarrier frequency and video line frequency. The frequency control word of the internal color subcarrier PLL and the subcarrier reset bit are transmitted via terminal 37 (GLCO) for optional use in an end system (for example, by a video encoder). The frequency control word is a 23-bit binary number. The instantaneous frequency of the color subcarrier can be calculated using the following equation:

Figure 2-16. VSYNC Position With Respect to HSYNC

2.5.2 Embedded Syncs

Standards with embedded syncs insert the SAV and EAV codes into the data stream on the rising and falling edges of AVID. These codes contain the V and F bits, which also define vertical timing. Table 2-3 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.

The P bits are protection bits:

Preamble 1 1 1 1 1 1 1 1 1 1 Preamble 0 0 0 0 0 0 0 0 0 0 Preamble 0 0 0 0 0 0 0 0 0 0 Status word 1 F V H P3 P2 P1 P0 0 0

Communication with the TVP5147M1 decoder is via an I2C host interface. The I2C standard consists of two signals, the serial input/output data (SDA) line and the serial input clock line (SCL), which carry information between the devices connected to the bus. A third signal (I2CA) is used for slave address selection. Although an I2C system can be multimastered, the TVP5147M1 decoder functions as a slave device only.

Because SDA and SCL are kept open drain at a logic-high output level or when the bus is not driven, the user must connect SDA and SCL to a positive supply voltage via a pullup resistor on the board. The slave addresses select signal, terminal 37 (I2CA), enables the use of two TVP5147M1 devices tied to the same I2C bus, because it controls the least-significant bit of the I2C device address.

2.6.1 Reset and I2C Bus Address Selection

The TVP5147M1 decoder can respond to two possible chip addresses. The address selection is made at reset by an externally supplied level on the I2CA terminal. The TVP5147M1 decoder samples the level of terminal 37 at power up or at the trailing edge of RESETB and configures the I2C bus address bit A0.

2.7 VBI Data Processor

The TVP5147M1 VBI data processor (VDP) slices various data services like teletext (WST, NABTS), closed caption (CC), wide screen signaling (WSS), program delivery control (PDC), vertical interval time code (VITC), video program system (VPS), copy generation management system (CGMS) data, and electronic program guide (Gemstar) 1x/2x. Table 2-6 shows the supported VBI system.

These services are acquired by programming the VDP to enable the reception of one or more vertical blank interval (VBI) data standard(s) during the VBI. The VDP can be programmed on a line-per-line basis to enable simultaneous reception of different VBI formats, one per line. The results are stored in a FIFO and/or registers. Because of the high data bandwidth, teletext results are stored in FIFO only. The TVP5147M1 decoder provides fully decoded V-Chip data to the dedicated registers at subaddresses 80 0540h−80 0543h.

2.7.1 VBI FIFO and Ancillary Data in Video Stream

Sliced VBI data can be output as ancillary data in the video stream in ITU-R BT.656 mode. VBI data is output on the Y[9:2] terminals during the horizontal blanking period. Table 2-7 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 the FIFO is 512 bytes. Therefore, the FIFO can store up to 11 lines of teletext data with the NTSC NABTS standard.

2.7.2 VBI Raw Data Output

The TVP5147M1 decoder can output raw A/D video data at twice the sampling rate for external VBI slicing. This is transmitted as an ancillary data block, although somewhat differently from the way the sliced VBI data is transmitted in the FIFO format as described in Section 2.7.1. The samples are transmitted during the active portion of the line. VBI raw data uses ITU-R BT.656 format having only luma data. The chroma samples are replaced by luma samples. The TVP5147M1 decoder inserts a four-byte preamble 000h 3FFh 3FFh 180h before data start. There are no checksum bytes and fill bytes in this mode.

2.10 Internal Control Registers

The TVP5147M1 decoder is initialized and controlled by a set of internal registers that define the operating parameters of the entire device. Communication between the external controller and the TVP5147M1 is through a standard I2C host port interface, as described earlier. Table 2-10 shows the summary of these registers. Detailed programming information for each register is described in the following sections. Additional registers are accessible through an indirect procedure involving access to an internal 24-bit address wide VBUS. Table 2-11 shows the summary of the VBUS registers.

Reserved H-PLL response time Reserved Power save

H-PLL response time

00 = Adaptive mode (default). 01 = Reserved mode. 10 = Fast mode. 11 = Normal mode. When in the Normal mode, the horizontal PLL (H-PLL) response time is set to its slowest setting. This mode improves noise immunity

and provides a more stable output line frequency for standard TV signal sources (e.g., TV tuners, DVD players, video surveillance cameras, etc.).

When in the Fast mode, the H-PLL response time is set to its fastest setting. This mode enables the H-PLL to respond more quickly to large variations in the horizontal timing (e.g., VCR head switching intervals). This mode is recommended for VCRs and also cameras locked to the AC power-line frequency.

When in the Adaptive mode, the H-PLL response time is automatically adjusted based on the measured horizontal phase error. In this mode, the H-PLL response time typically approaches its slowest setting for most standard TV signal sources and approaches its fastest setting for most VCR signal sources.

Power save

0 = Normal operation (default) 1 = Power save mode. Reduces the clock speed of the internal processor and switches off the ADCs. I2C interface is active and all

gains are automatically set to nominal values of 2 and 2304, respectively. If all 4 bits of the upper nibble are set to logic 1 (that is, no amplitude reference selected), then the back-end gain is set automatically to

unity.

If the input sync height is greater than 100% and the AGC-adjusted output video amplitude becomes less than 100%, then the back-end scale factor attempts to increase the contrast in the back end to restore the video amplitude to 100%.

Capture:

Setting a 1b in this register causes the internal processor to capture the current settings of the AGC status and the vertical line count registers. Because this capture is not immediate, it is necessary to check for completion of the capture by reading the capture bit repeatedly after setting it and waiting for it to be cleared by the internal processor. Once the capture bit is 0b, the AGC status and vertical line counters (3Ch/3Dh and 9Ah/9Bh) have been updated and can be safely read in any order.

Because this register is a double-byte register, it is necessary to capture the setting into the register to ensure that the value is not updated between reading the lower and upper bytes. To cause this register to capture the current settings, bit 0 of the status request register (subaddress 97h) must be set to a 1b. Once the internal processor has updated and can be read.

For an NABTS system, the packet prefix consists of five bytes. Each byte contains 4 data bits (D[3:0]) interlaced with 4 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 corresponding pattern bits P[3:0] and mask bits M[3:0]. The filter ignores hamming protection bits.

For a WST system (PAL or NTSC), the packet prefix consists of two bytes. The two bytes contain three bits of magazine number (M[2:0]) and five bits of row address (R[4:0]), interlaced with eight Hamming protection bits H[7:0]:

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

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 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).
