数据在不同系统和设备间互通互连的问题是视频通信领域的研究重点。文中研究了H.263+到H.264转码器中Intra帧的转码问题,对快速得到转码后的预测模式及预测方向做了深入的研究。仿真试验表明:文中提出的转码算法在保证转换编码效率的同时,灵活性和鲁棒性较好。
The problem of data interoperability among different systems and devices is the focus of research in the field of video communications. In this paper, the transcoding of Intra frames from H.263 + to H.264 transcoder is studied, and the prediction mode and prediction direction after transcoding are obtained. The simulation results show that the transcoding algorithm proposed in this paper has better flexibility and robustness while ensuring the efficiency of transcoding.
