Functional Description 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 10 inputs and performs source selection, video clamping, video amplification, A/D conversion, and gain and offset adjustments to center the digitized video signal. The TVP5147 supports one analog video output for the selected analog input video.
PAGE 17
Functional Description • • • • Up to 10 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, two S-video inputs, and two CVBS inputs The input selection is performed by the input select register at I2C subaddress 00h (see Section 2.11.1). 2.1.2 Analog Input Clamping An internal clamping circuit restores the ac-coupled video signal to a fixed dc level.
PAGE 18
Functional Description 2.2 Digital Video Processing Figure 2−2 is a block diagram of the TVP5147 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.
PAGE 19
Functional Description 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.

PAGE 21
Functional Description 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 2−8 through Figure 2−11. TI’s patented adaptive comb filter algorithm reduces artifacts such as hanging dots at color boundaries.
PAGE 22
Functional Description 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 2−12 illustrates the basic functions of the luminance data path.

Peaking Filter Response, PAL Square Pixel Sampling 2.2.3.1 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 which have bandwidth-limited color components. 2.
PAGE 24
Functional Description 2.4 Real-Time Control (RTC) Although the TVP5147 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.

Functional Description 2.5.1 Separate Syncs VS, HS, and VBLK are independently software programmable to a 1× pixel count. This allows any possible alignment to the internal pixel count and line count. The default settings for 525-line and 625-line video outputs are given as examples below. FID changes at the same transient time when the trailing edge of vertical sync occurs. The polarity of FID is programmable by an I2C interface.

Functional Description 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 TVP5147 devices tied to the same I2C bus, because it controls the least significant bit of the I2C device address.

Functional Description 2.7 VBI Data Processor The TVP5147 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.
PAGE 34
Functional Description 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.
PAGE 35
Functional Description 2.7.2 VBI Raw Data Output The TVP5147 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.

Functional Description 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 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 the Hamming protection bits.

Functional Description FIFO read data [7:0]: This register is provided to access VBI FIFO data through the I2C interface. All forms of teletext data come directly from the FIFO, while all other forms of VBI data can be programmed to come from registers or from the FIFO. If the host port is to be used to read data from the FIFO, then bit 0 (host access enable) in the VDP FIFO output control register at subaddress C0h must be set to 1 (see Section 2.11.66). 2.11.
