additional query :
i have to build any protocol for sending video image apart from the udp protocol and the what could the max size of the udp packet

Try keeping the size of your packets at or below 536 bytes. If you send a UDP packet that is too large for any of the routers between you and the peer, it will become fragmented. Even if all of the routers reassemble packets properly, if any of the fragments are dropped, the whole datagram will be dropped. You don't always receive any notification that this has occurred, thats why UDP is "unreliable".
Routers routinely drop packets when their queues overflow.
When sending within a LAN, it is unlikely for any packets to be dropped. Out across the hostile internet, things are not so simple.
