Adaptive joint source-channel coding for scalable video minimizes the reconstructed video distortion at the decoder subject to a constraint on the overall transmission bit rate budget.
Introduction
Adaptive Joint Source-Channel Coding (AJSCC) optimizes the rate allocation for scalable source and channel coding efficiently. There are some scenarios where the AJSCC can play a vital role. Firstly, multi-user environments and multi-user heterogeneous networks are the most likely candidate for the AJSCC, as shown in Fig. 1. Secondly, the AJSCC will have maximal impact, when resource constraints are inflexible. In the scenario depicted in Fig. 1, the video server requires video contents of different fidelities, such as high quality material for storage and future editing and lower bit-rate content for distribution. In traditional video communications over heterogeneous channels, the video is usually processed offline. Compression and storage...
