    • A method for concatenating MPEG-4 or H.263 segments is provided. The method includes extracting and comparing the VOL or picture header information of each segment. If the two segments have the same VOL or picture header information, the method merges the two segments directly by appending one segment to another to form a new bit stream. If the two segments have the different resolution, the method completely decodes and re-encodes the segments and then merges the segments. Otherwise the method takes the VOL or picture header information of one segment as reference to produce the new bit stream. The method parses the other segment frame at a time, re-encapsulates it according to the reference VOL or picture header information, and appends it to the one segment. During the process, the method only uses VLD to parse the other segment without using the tools of DCT, IDCT, ME, and MC.
    • 提供了一种连接MPEG-4或H.263段的方法。 该方法包括提取和比较每个段的VOL或图像头信息。 如果两个段具有相同的VOL或图像头信息,则该方法通过将一个段附加到另一段直接合并形成新的比特流。 如果两个分段具有不同的分辨率,则该方法完全对段进行解码和重新编码,然后合并段。 否则,该方法将一个段的VOL或图像头信息作为参考,以产生新的比特流。 该方法一次分析其他段帧,根据参考VOL或图片头信息重新封装,并将其附加到一个段。 在此过程中,该方法仅使用VLD来解析其他段,而不使用DCT,IDCT,ME和MC的工具。
