    Abstract: Caption data incorporated in an input coded bit stream conveying a video service is processed by recovering the caption data from the input coded bit stream, decoding the input coded bit stream to form a digital video signal composed of a sequence of frames, embedding the caption data in an ancillary data space of the digital video signal, and encoding the digital video signal to produce an output coded bit stream incorporating the caption data.

    Abstract translation: 通过从输入的编码比特流中恢复字幕数据,对输入的编码比特流进行解码,形成由帧序列组成的数字视频信号,嵌入字幕数据,处理包含在传送视频服务的输入编码比特流中的字幕数据 在数字视频信号的辅助数据空间中,并且对数字视频信号进行编码以产生包含字幕数据的输出编码比特流。

    Abstract: A method, a video processing system, and an electronic device are disclosed. A video transcoder may decode a compressed video data frame creating a decoded video data frame. The video transcoder may embed a network presentation timestamp in the decoded video data frame. The video transcoder may re-encode the decoded video data frame creating a transcoded video data frame. A field programmable gate array may compare the network presentation timestamp with a transcoder presentation timestamp to determine a timestamp offset.
