【摘要】：在视频传输中有两个重要的问题需要解决:1)在已知网络带宽以及丢包率的情况下如何分配信源和信道的编码速率;2)在信源编码速率限定的条件下如何选择编码的参数。针对问题2),分析了现有的主观质量模型VQMTQ,选择VQMTQ作为视频主观质量评价的指标。联合码率模型在给定目标码率时能够选择最佳的编码参数,使得编码后的视频主观质量尽可能高。该研究对于实际应用具有重要价值,保障了人眼的主观感受。
[Abstract]:There are two important problems in video transmission that need to be solved: (1) how to allocate the coding rate of the source and channel in the case of known network bandwidth and packet loss rate; (2) how to select the encoding parameters under the limit of the source coding rate. According to question 2, the existing subjective quality model (VQMTQ) is analyzed, and VQMTQ is chosen as the index of video subjective quality evaluation. The joint rate model can select the best coding parameters when the target rate is given, which makes the subjective quality of the encoded video as high as possible. This research has important value for practical application and ensures the subjective feeling of human eyes.
