Dealing with IP for Mobile in an MPEG World
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 use Internet Protocol (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 is explained, as well as the mechanisms adopted to allow “broadcast quality” to be achieved. Additionally, considerations for differences in the component interconnections are discussed.
