- 論文の詳細を見る
This paper introduces the design procedure of the contrived network TV broadcasting transcoder/encoder system, especially develops a new variable bit-rate (VBR) coding bit allocation strategy with a constraint channel bandwidth and consistent picture quality for multiple parallel video sequences broadcasting, which accommodates the complicated video sources with different frame rates and GOP structures, and combines the buffer control and the optimized macroblock (MB) coding mode selection. The proposed strategy absorbs several reasonable metrics in a hierarchical structure, and provides flexibility and promotion for resource allocation in multi-access scenario. Experimental results demonstrate the effect of the proposed scheme.
