    • Available storage media capacity for personal video recording increases continuously. metadata can be used to organize the recordings, search for content and access specific recordings. If metadata are embedded within the multimedia content itself, like DVB specific Service Information, which are multiplexed with the audio and video streams to form a MPEG-2 transport stream, a search based on this metadata would require an inefficient and time consuming search through all multimedia content stored. According to the invention metadata information is gathered, analyzed and processed to form metadata entities, which are amended by a reference to the content itself. A descriptor stream is formed from the resulting pairs of metadata entities and references to the content and is stored separately from the files comprising multimedia content. In this way, for data of an MPEG-2 transport stream the metadata can be accessed without a need to reparse the entire stream.
    • 用于个人视频录制的可用存储媒体容量不断增加。 元数据可用于组织录音,搜索内容并访问特定录音。 如果元数据被嵌入在多媒体内容本身内,如DVB特定服务信息,其与音频和视频流复用以形成MPEG-2传输流,则基于该元数据的搜索将需要所有的低效和耗时的搜索 存储多媒体内容 根据本发明,收集,分析和处理元数据信息以形成元数据实体,其通过参考内容本身进行修改。 从所得到的元数据实体对和对内容的引用形成描述符流,并且与包括多媒体内容的文件分开存储。 以这种方式,对于MPEG-2传输流的数据,可以访问元数据而不需要重新分析整个流。
