摘要

分布式视频编码(DVC)是基于分布式源编码思想的一种较新的视频编码范式。这种方法在编码器端不使用运动估计，并且允许实现低复杂度的编码方案。在DVC解码过程中，使用关键帧生成侧信息，并使用纠错编码原理进一步细化侧信息。本文研究了DVC边信息生成的基本方法。提出了一种新的边信息生成算法。给出了基于所述算法的新DVC方案的率失真性能评价。

Analysis of side information generation impact on distributed video coding performance

Distributed video coding (DVC) is a relatively new video coding paradigm based on distributed source coding ideas. This approach does not use motion estimation at the encoder side and allows implementing low-complexity encoding schemes. In the DVC decoding procedure turns to generation of side information using key frames and further side information refinement using the principles of error correction coding. The basic approaches to side information generation for DVC are considered in the paper. A new algorithm of side information generation is proposed. An evaluation of rate-distortion performance of the new DVC scheme based on the described algorithm is given.
