| Abstract: |
In this paper, a novel H.264-based multiple description coding (MDC) framework, called the prediction-based spatial polyphase transform (PSPT) multiple description video coding, is introduced to enhance the error-resilience ability and reduce the computational complexity of the H.264 codec. The proposed PSPT-MDC down-samples each input frame in both the horizontal and the vertical directions, forming four subframes. Instead of directly coding and transporting all the four subframes, two of them are predicted from the other two subframes. The proposed H.264-based PSPT-MDC video codec is then implemented on the TI TMS320C6416 digital signal processor with some optimizations to demonstrate its feasibility and attractive performance, in terms of the decoded video quality and error-resilience capability. |
