摘要 网络上传输图像与视频数据流所遇到的一个重要问题是信息包在传输过程中可能发生丢失或过度延时,从而造成解码信号的视觉质量严重下降。多描述编码旨在通过对同一个信息源编码成多个具有一定相关性的比特流,并在多个不同的信道上传输,以改善不可靠信道上传输的图像与视频信号质量。提出了一种基于H.263的视频信号多描述编码方法,实验结果显示了所提出方法的有效性。 Packet loss and delay in image or video communication on Internet is a big problem, as it finally results in degradation of the reconstruction image quality. MDC (Multiple Description Coding) is an alternative solution in solving this problem. In the MDC method, the same information source is encoded into multiple correlative streams, which are transferred in several channels separately. So it can improve the image and video quality transferred in the irresponsible networks. A MDC method based on H.263 is proposed, and experimental results show that the proposed algorithm is efficient.
