Abstract

Feedback and frame synchronization between media encoders and decoders is described. More particularly, the encoder can encode frames that are based on source content to be sent to the decoder. The encoder can determine whether the frame should be cached by the encoder and the decoder. If the frame is to be cached, the encoder can so indicate by encoding the frame with one or more cache control bits. The decoder can receive the frame from the decoder, and can examine the cache control bits to determine whether to cache the frame. The decoder can also decode the frame.
