Hi all,
I have implemented TCP/IP lean source code to transfer text messages through Lan card Using PIC16f877. Now i want to transfer Video output which is in MPEG1 or MPEG2 format. Is there any articles or work done about this then please share...Thanks
 

The LAN has either capable of 10Mbits/sec or 100Mbits/sec. For transfering live color video over this LAN, see that compressed formats like MPEG1 or MPEG2's data rate is sufficiently less than the above mentioned rates.
 

i think u need to implement an h.323 protocol stack over tcp/ip for video transfer . h.323 standard is available in a link provided in this site(though i dont remember that!).google mpeg and h.323 .

Needless to say, that's an interesting although cumbersome project.

Good luck, boys!

Well, using a PIC ? holly....

Basically you need to implement a RTP protocol
I think its better you go straight to the FAQ's :D

The basic RFC 1889 - RTP: A Transport Protocol for Real-Time Applications
from 1996 is a MUST read, and with it
you may manage to start sending stuff.

Then you get RFC 3267 for AMR Codecs ( nice VoIP )
And RFC 3714 states some points in net congestion due traffic
and packet loss, and some sugestions to bypass ...

More info in video conferencing in RFC 3550

Surely you got a nice way to go...
But ARM cpu's are easy an nice to program/debug and have more resources...

Good luck....
