Abstract

An MPEG system layer compressed-domain editing technique is proposed to facilitate the delivery and integration of multiple segments of MPEG files, residing on remote databases. Various multimedia applications, including retrieval and summarization, split MPEG files into small segments along shot boundaries and store them separately. This traditional method requires extra management and storage payload, provides only fixed segmentations, and may not be play smoothly. In order to solve this problem, our MPEG system-domain editing tool directly extracts video-audio information from the original MPEG sources and combines them to generate a single MPEG file. Manipulated wholly in the system bitstream domain, this method does not require decoding, re-encoding, and re-synchronization of audio and video data. Thus, it operates in real-time and provides great flexibility. This composite MPEG file can be transmitted and displayed through general Web interfaces. The proposed method is applied to our video retrieval, video summarization, and video editing systems, and has shown its great advantages.

使用压缩域系统流编辑技术的通用MPEG内容访问

提出了一种MPEG系统层压缩域编辑技术，以方便驻留在远程数据库中的多段MPEG文件的传输和集成。各种多媒体应用程序，包括检索和摘要，沿着镜头边界将MPEG文件分割成小段并单独存储。这种传统方法需要额外的管理和存储负载，只提供固定的分段，并且可能不太流畅。为了解决这个问题，我们的MPEG系统域编辑工具直接从原始的MPEG源中提取视频音频信息，并将它们组合成一个单一的MPEG文件。完全在系统比特流域中操作，这种方法不需要解码、重新编码和重新同步音频和视频数据。因此，它是实时运行的，并提供了很大的灵活性。该复合MPEG文件可以通过一般的Web接口进行传输和显示。该方法已应用于我们的视频检索、视频摘要和视频编辑系统中，显示出了很大的优势。
