In 4-Ch pixel-interleaved mode, TVP5158 also supports Half-D1 and CIF format data multiplexed at 54
MHz. The output DVO_A is used in this mode. The output clock OCLK_P is synchronized with all four
channels data.
3.8.2.3 Metadata Insertion for Non-Interleave Mode and Pixel-Interleaved Mode
In non-interleaved mode and pixel-interleaved mode, the video detection status (VDET) has also been
inserted in MSB of SAV/EAV control byte. Table 3-7 shows VDET status insertion in SAV/EAV codes.

In the pixel-interleaved mode, Channel ID is inserted in the horizontal blanking code as Table 3-8. The
backend chip can easily identify the video data from which video decoder channel by inserted Channel ID.

In the pixel-interleaved mode, Channel ID can also be inserted in 4 LSBs of SAV/EAV control byte
replacing protection bits as Table 3-9.
