摘　　要：传输流(TS流)广泛应用于数字电视和其它多媒体领域,是最常见的码流格式之一。随着新媒体等业务的快速发展,TS收录已成为内容提供商和内容运营商获得节目素材和进行节目交流的重要手段。在充分分析现有TS收录方法优缺点的基础上,提出一种新的收录方法,该收录方法具有收录效率高,满足实时性业务需求的优点,又能在收录任务异常时帮助排查异常原因,恢复收录内容,并讨论了生成的压缩数据的安全存储。TS（Transport Stream） , widely used in digital television and other multimedia fields, is one of the most common stream formats. With the rapid development of new media business, TS recording be- comes an essential means for content providers and operators to obtain program materials and exchange pro- grammes. Based on analysis of advantages and disadvantages of existing recording methods, a novel re- cording method is proposed.
