碩士 === 國立清華大學 === 資訊工程學系 === 97 === The transmission for the video stream over the error-prone channel is the indispensable subject to discuss in the present days. By the variant video compressed coding standards such as H.264 and MPEG4, the video stream can possess a highly compressed rate to transmit in the real-time display. However, once the packet erasures happened, it can cause serious error propagation during the transmission process. Due to the error-catalyzed situation, the error concealment techniques utilize the remaining spatial and temporal relativity to reconstruct the corrupted data is necessary. The discussion in this thesis is mainly attempted to introduce a novel error concealment structure constructed by the game theory. In order to adapt the various circumstances of the possible image contents, there are four different Spatial Error Concealment algorithms to provide. One of them is a modified multi-directional interpolation used to enhance the multiple edge erroneous blocks; another one is also a modified best neighborhood matching efficiently for shortening the processing time; the remaining method are Bilinear interpolation and the directional interpolation. These four methods are selected by playing a game theory based structure to make it consider much broader with the variant spatial relativities. The best strategy which possesses the highest payoff value is considered as the suitable algorithm to reconstruct the erroneous block.
