Errors In The Improvement Of Video Communication Based On TV Model Hiding Technology Research

With the rapid development of the third generation mobile communication systemsand IP networks, real-time video communication is gradually becoming one of the mainbusiness of the communication. Mobile channel and error-prone, time-varyingcharacteristics of band-limited, and the introduction of a large number of random errorsand burst errors due to multipath reflections and fading so that the bit error rate of themobile channel is larger than the cable channel. At the same time, due to bandwidthlimitations, the video information must be carried out prior to transmission highlyefficient compression coding, most video coding standards currently used time andspatial prediction, such that the encoded video stream of the channel errors are morevulnerable. In order to reduce the impact of channel errors on the quality of decoding,must be combined with the practical application of the transmission characteristics of thechannel, the use of effective error handling mechanism, error control technology hasbecome the key technology of video communications. Therefore, the selected researchdirections in this article is based on the research of error concealment in videocommunication in improved TV model.Firstly, video communication error concealment technology research brief videoerror concealment technology development. Outlines the basic principles of videocompression coding standard, new features and error control technology, and summarizesthe performance characteristics.Secondly, through the integrated study on the basic principles of the existing videocompression coding technology and do their own characteristics summarized.Again, the error concealment in video transmission technology classificationsummarized analysis of three aspects, respectively, from the encoding side, the decodingside, and codec interaction-based video compression coding standard error concealmenttechniques. Finally, the existing error concealment technology based on partial differentialequations, in particular TV model and CDD model-based error concealment techniqueshave been studied, analyzed existing algorithms for the inadequacies of the existingmethods, improved TV error concealment technique, experimental resultsdemonstrate improved method can get a higher quality of the restored image. In addition,the use of a linear interpolation algorithm and CDD model were carried out experimentalsimulation, and these types of results were compared by the results of the comparison cansee the advantages and disadvantages of various methods.
