摘要： A data processing system comprises a cluster of devices (16) interconnected for the communication of data in streams, particularly digital audio and/or video data. One of the devices (10) is a source device for at least two data streams to be sent to one or more other devices (12, 14) as destination devices of the cluster. To enable synchronisation of the stream presentations by the destination devices, some or all of the devices (10, 12, 14) carry respective tables (11, 13, 15) identifying, for that device, an identifier for each type of data stream that the device can process together with the processing delay for that stream. The or each such table is accessible via the cluster connection (18) to whichever of the devices, at source, destination or in between for the signal, is handling application of the necessary offsets.

摘要： The present invention relates to a multimedia player providing a generic and easy to use mechanism for accurate task scheduling. Said multimedia player processes a encoded digital data stream (IS) in order to supply audio and video signals (SO, SC) to an audio-visual production system (LS, MON). The multimedia player in accordance with the invention comprises a demultiplexer (DEMUX) for splitting the encoded digital data stream into an audio stream (AS) and several video streams (VS1 to VSn). The multimedia player also performs the tasks of audio decoding and rendering (DR), to decode (ADEC) the audio stream, to filter the decoded audio frames (AF) provided by the decoding and to render (AREN) said audio frames; decoding (DEC) the video streams, to provide video objects whose decoded video frames (VF1 to VFn) are stored in video buffers (BUF1 to BUFn); and rendering (REN) the decoded video frames stored in the video buffers. Finally, the multimedia player comprises a scheduler for registering the three previous tasks, assigning a target time to said tasks, and controlling the execution of the tasks as a function of the target time.

摘要： A radio VOD (Video-On-Demand) system is disclosed. A server provides a video file and an audio file, and a server manager manages the server so as to transmit a video file and an audio file at a user's request. An exchange converts the video file and the audio file provided from the server through a network to the corresponding video and audio signals. A mobile terminal receives the video and audio signals from the exchange through separate channels, and reads only the user requested data from the received video and audio signals. The mobile terminal comprises first and second tuners for separately receiving the video signal and the audio signal, respectively; a signal processor for detecting a video signal and an audio signal, selected by the user, from the video and audio signals received through the first and second tuners; first and second decoders for decoding the video and audio signals detected by the signal processor, respectively; a video display for outputting the decoded video signal; and an audio output device for outputting the decoded audio signal.

摘要： When audio information is multiplexed at the next frame in an SB insertion judging unit (124), a synchronous word and the length of a header are subtracted from the distance between the end of the previous frame and the multiplex starting position of the audio information, to calculate a multiplexable length of video information. When the length of important information is greater than the video multiplexable length, it is judged to be necessary to multiplex a stuffing bit stream. In this case, a frame constructing unit (127) inserts redundancy bits from the end position of the previous frame to the front end of the synchronous word. Therefore when the transmission data are multiplexed, the important information can be prevented from being divided into a plurality of frames.
摘要翻译：当音频信息在SB插入判断单元（124）中的下一帧被多路复用时，从前一帧的结束和音频信息的多路开始位置之间的距离中减去同步字和头的长度，以计算视频信息的可复用长度。当重要信息的长度大于视频可复用长度时，判断需要复用填充比特流。在这种情况下，帧构成单元（127）将冗余位从前一帧的结束位置插入同步字的前端。因此，当发送数据被复用时，可以防止重要信息被划分为多个帧。

摘要： While recorded stream data to which time stamp information is added to every packet is reproduced, the time is managed using the time stamp information. The video reproducing time judged by the user and indicated by the respective picture display times of I, B, and P is different from the time indicated by the time stamp information. Therefore, if the time is managed for the stream data recorded on an information storage medium only by the time stamp information, the display time (video reproducing time) of the display to the user is not controlled properly. According to the invention, a time relationship table showing the relationship between the time stamp information included in the stream data at the start time position of each I picture and the display time information (PTS or field information) about the display to the user is contained in part of management information.
摘要翻译：当再现时间标记信息被添加到每个包的记录流数据时，使用时间戳信息来管理时间。由用户判断并由I，B和P的各个图像显示时间指示的视频再现时间与时间戳信息指示的时间不同。因此，如果仅通过时间戳信息对记录在信息存储介质上的流数据管理时间，则不能适当地控制对用户的显示的显示时间（视频再现时间）。根据本发明，包含在每个I图像的开始时间位置处包含在流数据中的时间戳信息与关于用户的显示的显示时间信息（PTS或场信息）之间的关系的时间关系表被包含部分管理信息。

摘要： A synchronization module executes independently of a multimedia application and serves requests for timing data which the multimedia application uses to synchronize display of motion video and audio data of a multimedia display. The multimedia application disregards the motion video playback mechanism provided by the multimedia authoring tool by which the multimedia application is created and instead directly controls movement of individual objects of a motion video scene in accordance with time information received from the synchronization module. The timing data is relative to the beginning of playback of accompanying audio data such that audio and video of the multimedia display are synchronized regardless of the particular processing speed of the computer system within which the multimedia application executes.
