Abstract:
Methods, apparatus, and computer readable media may adjust an encoding rate based on network conditions between a transmitter and a receiver. Either the transmitter, receiver, or both the transmitter and receiver may determine the encoding rate. In one aspect, a ratio of received network data to transmitted network data is determined. An encoding parameter is then determined based on the determined ratio. In one aspect, the encoding parameter may be used to adjust an encoder. In another aspect, the determined encoding parameter may be transmitted to an encoding or transmitting node. In another aspect, an amount of data buffered in a network is determined. A sustainable throughput of the network is also determined. A transmission rate is then determined based on the sustainable throughput and the amount of data buffered. An encoding parameter is then adjusted based on the transmission rate.
