Is there any limitation on max. bit rate for H264 decoder for multiple 1080i/p channels?

Hi,

I want to decode 4 1080i or 4 1080p channels in DM816x at 30 fps each.

Is there any max. bit rate constraint for each of the 1080i or 1080p encoded frame, which will be submitted to H264 decoder of Netra ?

Can I decode 4 1080i/p encoded frames @30 fps and 15 Mbps each ?

Regards,
Sweta

    Sweta,

    It is possible to have your use case on DM8168. However I have concerns about parsing the streams on A8, please check the parser's performance on your system.

    Hi Vimal,

    My use case is as follows - Receive 4 1080i or 4 1080p streams from n/w (from RTP/RTSP server), decode all 4 of them, scale down and display as mosaic.

    The reason for asking decoder's performance is, I will receive these streams from HD cameras, having bit rate for each stream as at least 15 Mbps.

    If HDVICP capable enough to decode 4 1080P_30 or 4 1080i_30 streams at 15 Mbps each (aggregate bit rate = 15*4 = 60 Mbps).

    By parser, do you mean module which generates encoded frame out of RTP packets ? If yes, that shouldn't be an issue for me.

    Please let me know if I have misunderstood your concern for parser.

    Also let me know whether M3/HDVICP core can handle 4 1080p/i encoded data at 15 Mbps and 30 fps each or not.

    Regards,
