摘要：
A technique for streaming and a client device that uses the technique are disclosed herein. The disclosed technique determines context complexity of streamed data and determines whether to discard or select the streamed data for a future reference frame based on the context complexity of the streamed data. The streamed data is discarded if the content complexity is higher than a content complexity threshold, and the streamed data is selected if the content complexity is not higher than a content complexity threshold. This is based on the realization that error propagation in the case of a less complex video sequence is not very bothersome to the end user experience whereas corruption will be very severe in cases of highly complex sequences.
