Abstract
We show the performance of the proposed error resilient video coding system, which dynamically replaces reference pictures in inter-frame coding according to the acknowledgement signals from the decoder. Scalability to the quality of the network is a feature of the system. A poor network condition in its way results in a certain picture quality and a good network condition enhances the picture quality. Two types of signaling, ACK and NACK, are evaluated. The evaluation includes the influences of the backward channel errors as well as those of the forward channel errors. ACK signaling outperforms NACK signaling especially under the existence of the backward channel errors which are highly correlated with the forward channel errors.Keywords
