Dealing with IP for Mobile in an MPEG World

Rich Chernock

Until recently, MPEG-2 Transport Streams have been the only means used to carry Digital Television (DTV). MPEG-2 provides the necessary underpinnings for broadcast quality delivery of DTV content, including a well-established timing and buffer model. The new ATSC Mobile DTV standard has chosen to instead use IP transport for both streaming and file content. Compatibility with other emerging mobile systems was one of the reasons for this choice. — This paper explains the use of IP transport in ATSC Mobile DTV for both streaming and file content. The protocol stack will be explained, as well as the mechanisms adopted to allow “broadcast quality” to be achieved. Additionally, considerations for differences in the component interconnections will be discussed.
