摘要： A method of presenting, at a client terminal, a video program stored in a server linked with the client terminal via transmission path of a limited transmission band width. Each frame of the video program comprises a basic data portion and at least one level of quality supplement data portions. In the method, in response to one of play control commands from a user, the client terminal determines a start position in the video program according to the issued play control command. The play control commands includes a play, a stop, a head search, a jump forward and a jump backward command. In response to the issued play command, the terminal obtains and uses the basic data portions for playing the video program. In response to the stop command, the terminal obtains the quality supplement data portions for the last displayed frame and uses them for displaying a quality-enhanced version of the last displayed frame.

摘要： A video and audio reproducing apparatus is provided with a re-synchronization controlling portion (20) for carrying out operation control with respect to re-synchronization of video and audio which are transmitted via an IP network, wherein the delay times of video data and audio data are controlled by the video delay controlling portion (21) and audio delay controlling portion (22), respectively, thereby carrying out re-synchronization. At this time, the re-synchronization controlling portion (20) judges re-synchronization timing on the basis of the audio level of audio data, encoding video type of video data, data transmission status and user operation, etc., and at the same time, judges the priority for which mode of the video priority mode or the audio priority mode the re-synchronization is carried out, on the basis of a fluctuation in the arrival time of audio data, data transmission status, contents of video data and audio data and user operation, etc. And, the delay amount for synchronization is determined by executing a prescribed re-synchronization algorithm at the re-synchronization timing to control the video delay controlling portion (21) and the audio delay controlling portion (22), wherein disturbances in video and audio can be mitigated when carrying out re-synchronization.
