The backend chip needs to keep only the active video line and ignore the dummy line. The start code of the dummy line is different with active video line. Table 3-14 shows the bit assignment and field definition of 4-Byte start code for the Dummy Line.

Audio Sub-System Functional Diagram 3. 9. 3 Serial Audio Interface The timing for the TVP5158 serial audio interface is shown in Figure 3-18. The TVP5158 audio data output (SD_R) and frame sync pulse (LRCLK) are aligned with the falling edge of the bit clock (BCLK). The TVP5158 audio data is delayed one BCLK cycles from the falling edge of the frame sync pulse.
