    • For a compressed video stream formed of a sequence of compressed data packets, each compressed packet is assigned to a frame by processing the undecoded data packet. A frame includes packets. A first plurality of frames is assigned to a first sliding window and a second plurality of frames is assigned to a second sliding window. The first and second sliding windows have different frames. A first window indicator is calculated by determining a first indicator representing an average number of packets per frame within the first window, and/or a second indicator representing size information of the data within the first window. A second window indicator is calculated by determining a third indicator representing an average number of packets per frame within the second window, and/or a fourth indicator representing size information of the data within the second window. The first and the second window indicators are compared.
    • 对于由压缩数据分组序列形成的压缩视频流,通过处理未解码的数据分组将每个压缩分组分配给一帧。 帧包括数据包。 第一多个帧被分配给第一滑动窗口,并且第二多个帧被分配给第二滑动窗口。 第一和第二滑动窗口具有不同的框架。 通过确定第一指示符来计算第一窗口指示符,第一指示符表示第一窗口内的每帧的平均数量,和/或表示第一窗口内的数据的大小信息的第二指示符。 通过确定表示第二窗口内的每帧的平均分组数量的第三指示符和/或表示第二窗口内的数据的大小信息的第四指示符来计算第二窗口指示符。 比较第一和第二窗口指标。

    • An image block is encoded by an inter-layer prediction into a first encoded image block and also encoded into a second encoded image block based on an encoding mode that excludes inter-layer prediction. The encoded first and second image blocks are decoded into reconstructed first and second image blocks, respectively. The first encoded image block is inserted into the encoded video stream. When encoding image blocks by an encoding mode that references the reconstructed first image block, the reference to the reconstructed second image block is changed. The image block encoded in this way is inserted into the encoded video data stream to achieve both a high compression rate with high image quality and low complexity in transcoding that can be used with different end devices by a scalable encoded video data stream, such as a video-on-demand service.
    • 图像块通过层间预测编码为第一编码图像块,并且还基于排除层间预测的编码模式而编码为第二编码图像块。 编码的第一和第二图像块分别被解码成重建的第一和第二图像块。 将第一编码图像块插入编码视频流中。 当通过引用重建的第一图像块的编码模式对图像块进行编码时,改变对重构的第二图像块的引用。 以这种方式编码的图像块被插入到经编码的视频数据流中,以实现具有高图像质量的高压缩率和代码转换的低复杂度,其可以通过可缩放编码的视频数据流(诸如 视频点播服务。
