Hi,

De-muxing is done by the video port, it is not done by tvp5158. TVP5158 muxes multiple video streams and sends it ver 8bit interface.

Thx,

Hi Brijesh,

I mean how de-muxing is done? Is there any code to do this job in DVRRDK. Or do you mean de-muxing is done by hardware?

Hardware does that.

Hi,

Essentially, hardware does demuxing and we could store the frame from each channel in a separate buffer.
