| Abstract: | In order to solve the problem of compatibility of TV STB playing standard-definition and high-definition videos and the problem of wasting transmission bandwidth, and combined with existing digital TV coding standards and H.264 SVC basis, the Article studies H.264 extending to MPEG-2 base layer after taking consideration of actual application situation, has designed SVC based on hybrid standards and proposed detailed coder-decoder system frame of SVC based on hybrid standards,and has conducted analysis on key problem and proposed corresponding resolutions with satisfying feasibility at the same time. Design of SVC based on hybrid standards has realized cross-standard video playing, increased coding efficiency, and provided theoretical basis to video coding technology development and digital TV high-definition popularization. |
