A case study of bitstream syntax reconfiguration for MPEG Internet video coding

In this paper, we propose a bitstream syntax reconfiguration approach to improve coding efficiency of video codec. The video compression within a codec is conducted by several compression tools, and the usage of the tools is dependent on how bitstream syntax is composed. Accordingly, proper modification on the bitstream syntax may leads to the improved usage of compression tools, resulting in the enhanced compression efficiency. We studied this assumption through reconfiguration of MPEG Internet video coding (IVC) bitstream syntax. We allowed the use of intra prediction during the inter-frame compression process. Experimental results show that the proposed method can increase the coding efficiency up to 2.1%.
