摘要： A method and apparatus for encoding/decoding a multi-layer interlaced video signal having macroblocks coded in an interlaced manner is provided. The method includes determining whether a pair of macroblocks of a current layer are of a frame type and a corresponding pair of macroblocks of a lower layer are of a field type; and predicting and encoding a macroblock of the current layer by interpolating information of the top or bottom field of a corresponding macroblock of the lower layer, if the pair of the macroblocks of the current layer are of the frame type and the corresponding pair of the macroblocks of the lower layer are of the field type, and the top and bottom fields of the corresponding pair of the macroblocks of the lower layer have been coded in different prediction modes.

摘要： A client for playing a video stream and a method thereof adaptively control the video play in accordance with variable communication environments and the size of the video stream to be transmitted. The client includes a demultiplexer for generating elementary stream (ES) packets by demultiplexing a video stream; a FIFO buffer for temporarily storing the ES packets; a play timing modification unit for reducing a gap of a play time caused by a burst error by modifying time stamps of the ES packets that exist in the FIFO buffer if it is judged that the burst error occurs; and a video decoder for generating an output video by decoding the ES packets of which the time stamps are modified. The client can relatively improve the quality of the video streaming in multimedia communications through a wireless or wire network.
摘要翻译：用于播放视频流的客户端及其方法根据可变通信环境和要发送的视频流的大小自适应地控制视频播放。客户端包括：解复用器，用于通过解复用视频流来生成基本流（ES）分组; 用于临时存储ES分组的FIFO缓冲器; 播放定时修改单元，用于通过修改存在于FIFO缓冲器中的ES分组的时间标记来减少由突发错误引起的播放时间的间隙，如果判断出突发错误发生的话; 以及视频解码器，用于通过解码修改了时间戳的ES分组来产生输出视频。客户端可以通过无线或有线网络相对提高多媒体通信中视频流的质量。
