Output Formatter
The output formatter is responsible for generating the output digital video stream. Table 3-4 provides a
summary of line frequencies, data rates, and pixel counts for different input standards. TVP5158 supports
non-interleaved output mode, pixel-interleaved output mode and line-interleaved output mode. The
non-interleaved mode is similar to the TVP5154A device, except that a single fixed clock output is used. In
the interleaved modes, the video output data from multiple decoder channels are multiplexed together and
then output to a single 8-bit or 16-bit port. The video output data from selected channels can be
interleaved on a pixel or line basis.

Non-Interleaved Mode
In the non-interleaved mode, the YCbCr digital output is programmed as 8-bit ITU-R BT.656 parallel
interface standard. Depending on which output mode is selected, the output for each channel can be
un-scaled data or scaled data. Also each video output port can be selected to output the video data from
any 1 of 4 video decoders. Table 3-5 shows the detailed information about non-interleaved mode.

Pixel-Interleaved Mode
Each video decoder supports multiplexing two or four channels ITU-R BT.656 format data together on a
pixel basis. The output from each video decoder channel is still ITU-R BT.656 format. After the processing
in output formatter, two or four channels video data has been interleaved together by strictly one pixel
from each channel.
The pixel-interleaved mode is dedicated for the backend chip which has limited video input ports.
Table 3-6 gives the output port configuration for pixel-interleaved mode.
