  • Systems and methods for transmitting and receiving data streams with feedback information over a lossy network
    Patent number: 7974233
    Abstract: Systems, apparatus, and methods are provided to enhance transmitting and receiving video data streams with feedback information over a lossy and/or congested network. The systems, apparatus, and methods may optimize retransmission for lost packets or lost data frames. Optimizations are also provided to select reference frames in a data stream so that block errors are contained when RPS is used to encode data frames. Optimization in decoding may include reconstructing high-resolution data frames from low-resolution data frames.
