TVP5158 also supports multiplexing 4-Ch Half-D1 and 1-Ch D1 data together and then output through
DVO_A at 108 MHz. The backend chip can use Half-D1 to generate CIF format by dropped one field.
Pleas note that the line-interleaved mode does NOT strictly output one line from each decoder channel
sequentially. The order of multiplexed the video line data is based on the availability of video output data
from each decoder channel. Therefore, it is possible to output two consecutive lines from the same
decoder channel or to skip one decoder channel output.
3.8.3.3
8-Ch Line-Interleaved Mode
Two TVP5158 devices can be cascade connected and work as single 8-Ch video decoder. In cascade
mode, the port DVO_C and DVO_D of master TVP5158 (first stage) can be configured as the video input
interface. The DVO_A and DVO_B of master TVP5158 are configured as the output interface for two
devices. This mode is dedicated for the backend chip with extremely limited input ports.
In the video cascade mode, the open-drain interrupt request (INTREQ) outputs from the first and second
stages can be combined using a wired-OR connection.
Typical applications with cascade mode show in the following diagrams.

Preview.
