Title: BUFFER LEVEL SIGNALING FOR RATE ADAPTATION IN MULTIMEDIA STREAMING
Abstract:
In a multimedia streaming network where a client has a receiver buffer to store packets received from a server to compensate for difference between data transmission amount by server and data usage amount by client, server should be able to adapt the data transmission rate based on the status of the receiver buffer. For rate adaptation purposes, server reconstructs a list of packets in the receiver buffer based on information provided by client. Information signaled to server is indicative of the next unit to be decoded and the sequence number of the packet to which the next unit to be decoded belongs, or the next packet to be decoded in client, the DON number of the next NAL unit or the sequence number of the packet carrying the next NAL unit to be decoded and the DON indicative of the decoding order of that next NAL unit.
