Abstract:
For use with a decoder buffer capable of receiving streaming data packets over a data network from a streaming transmitter and storing said data packets in a plurality of access units for subsequent retrieval by a streaming data decoder, a delay budget controller comprising:a first controller capable of monitoring at least one network parameter associated with said data network; a second controller capable of monitoring in said decoder buffer a delay budget region comprising a sequence of access units that are to be accessed sequentially by said data decoder, said delay budget region comprising a retransmission region and a late region separated by a temporal boundary, wherein said second controller detects missing data packets in said retransmission region and said late region and, in response to detection of a missing data packet in said retransmission region, transmits a retransmission request for said missing data packet to said streaming transmitter, and wherein said second controller is capable of adjusting said temporal boundary to thereby advance or retard said transmission of said retransmission request.
