摘要： A video switching system detects speaking information of at least one speaker in a video conference according to a reference time. One participant is regarded as one speaker if the one participant speaks longer than the reference time. The video switching system determines a main speaker of the at least one speaker according to the speaking information of the at least one speaker. The video switching system calculates an image switching frequency, and determines whether to switch to a video image of the main speaker according to the image switching frequency. The video switching system calculates a response time if determining to switch to the video image of the main speaker, and adjusts the reference time according to the image switching frequency and the response time.

摘要： An entropy decoding device offers all nodes on a decoding tree, and a most probable symbol for each node, and predicts presumptive information of a next node. The entropy decoding device decodes an encoded bit stream, and output a decoded content that includes real information of the next node. The entropy decoding device further generates a flush instruction to the table look-up module, when the prediction misses, and updates the most probable symbol.

摘要： An entropy decoding method includes retrieving video data corresponding to an microcode, operating an entropy decoding operation on the video data to acquire a result, and retrieving video data corresponding to a subsequent microcode according to a MPS synchronously. The method further includes determining if the MPS matches the result, and operating an entropy decoding operation according to the subsequent microcode on the video data corresponding to the subsequent microcode if the MPS matches the result.
摘要翻译：熵解码方法包括检索对应于微码的视频数据，对视频数据进行熵解码操作以获取结果，并且同步地根据MPS检索对应于后续微码的视频数据。该方法还包括确定MPS是否匹配结果，并且如果MPS与结果匹配，则根据随后的微代码对与后续微代码相对应的视频数据进行熵解码操作。

摘要： A video decoding method includes receiving video data and transforming the video data from a Huffman tree to at least one full tree and at least one one-side tree. One microcode corresponding to the video coding standard that has encoded the received video data is read where a format of the read microcode is determined. The method further includes reading video data from the transformed video data according to the consuming length of the read microcode if the format of the read microcode is a leaf, and decoding the read video data according to the decoding field of the read microcode to output a decoding result.
