Abstract
An encoder/decoder system usable to decrease the probability of a failed transmission over a lossy wireless network. In one embodiment, data packets unsuccessfully sent over the wireless network may be retransmitted a particular number of times, depending on how important the data in the lost packet is. In another embodiment, when a number of transmission failures is determined to exceed a predetermined threshold, it may be signaled that multiple reference frames should be used for encoding predictions.
Claims16
A method comprising:
- transmitting a plurality of encoded data packets over a wireless network;
- receiving acknowledgment signals for each of said plurality of encoded data packets when successfully transmitted;
- and
- determining if a number of transmission failures exceeds a predetermined threshold, and if so,
- signaling that multiple reference frames should be used for encoding predictions.

A system comprising:
- a wireless network;
- a client coupled to said wireless network, said client including a decoder and a receiver;
- a server coupled to said wireless network, said sever including an encoder and a transmitter, wherein said server is to,
- transmit a plurality of encoded data packets over the wireless network to said client;
- receive acknowledgment signals for each of said plurality of encoded data packets when successfully transmitted to said client;
- and
- determine if a number of transmission failures exceeds a predetermined threshold, and if so,
- signal that multiple reference frames should be used for encoding predictions.
