    • Auxiliary information (150) representing binary or multi-level (M≧2) logical values is embedded into successive segments (110) of an audio, video or other data signal in response to a user request to download the data signal via an on-line distributor (350) on a computer network such as the Internet. To avoid unnecessary delays in providing the data signal to the user, the data signal is pre-processed to provide two sets or copies of data (230, 235). One set (230) of the data contains segments with an embedded binary “0”, while the other set (235) contains corresponding segments with an embedded binary “1”. Successive segments are selected from one of the two sets to provide a time-multiplexed composite data signal (230) that has the desired content, but with an embedded binary data sequence that identifies the user.
    • 代表二进制或多级(M≥2)逻辑值的辅助信息(150)被嵌入到音频,视频或其他数据信号的连续段(110)中,以响应于用户通过在线数据信号下载数据信号的请求, 线路分配器(350)在诸如因特网的计算机网络上。 为了避免向用户提供数据信号的不必要的延迟,数据信号被预处理以提供两组或多个数据副本(230,235)。 一组(230)数据包含嵌入二进制“0”的段,而另一组(235)包含具有嵌入二进制“1”的相应段。 从两个组中的一个组中选择连续分段以提供具有所需内容的时间复用复合数据信号(230),但是具有识别用户的嵌入式二进制数据序列。

    • A video compression system and method for compressing video data for transmission or storage by reducing the temporal redundancy in the video data is described. A frame of video data is divided into a variable number of blocks of pixel data of varying size, and each block of data is compared to a window of pixel data in a reference frame of pixel data, typically the previous frame. A best matched block of pixel data is selected from the window of pixel data in the reference frame, and a displacement vector is assigned to describe the selected block location in the reference frame relative to the current block of pixel data. The number and size of the blocks of pixel data are permitted to vary, in order to adapt to motion discontinuities in the sequential frames of pixel data. This is to allow prediction blocks of pixel data in the current frame to be smaller in areas of high activity, while maintaining high levels of compression, achieved by using larger prediction blocks, in areas of the frame with low levels of activity. A frame of predicted pixel data is assembled from variable size blocks of prediction data and subtracted from the current frame of pixel data. Only the residual difference, the displacement vectors and an indication of the block sizes used in the prediction are needed for transmission or storage.
    • 描述了通过减少视频数据中的时间冗余来压缩用于传输或存储的视频数据的视频压缩系统和方法。 视频数据的帧被分成可变数目的不同大小的像素数据块,并且每个数据块与像素数据的参考帧(通常为前一帧)中的像素数据的窗口进行比较。 从参考帧中的像素数据的窗口中选择最佳匹配的像素数据块,并且分配位移矢量以相对于当前像素数据块来描述参考帧中的所选块位置。 允许像素数据块的数量和大小变化,以便适应像素数据的连续帧中的运动不连续性。 这是为了允许当前帧中的像素数据的预测块在高活动性的区域中较小,同时通过使用较大的预测块在具有低活动水平的帧的区域中保持高水平的压缩。 预测像素数据的帧由可变大小的预测数据块组合并从当前像素数据帧中减去。 传输或存储只需要残差,位移矢量和预测中使用的块大小的指示。
