The ATSC Data Broadcast Standard defines protocols for data transmission compatible with digital multiplex bit streams constructed in accordance with ISO/IEC 13818-1 (MPEG-2 Systems). The standard supports data services that are both TV program related and non-program related. Applications may include enhanced television, webcasting, and streaming video services. Data broadcasting receivers may include PCs, televisions, set-top boxes, or other devices. The standard provides mechanisms for download of data, delivery of datagrams and streaming data.
Note: Users are cautioned that there is a conflict in the assigned value for the MGT table_type identifying the LTST (Section 11.7). ANSI/SCTE 65 2002 assigned MGT table_type values for the Aggregate Extended Text Table (AETT) to the range 0x1100 through 0x11FF, while the current version of A/90 indicates the MGT table_type for the LTST is value 0x1180. A/90 is in the process of being revised to change the MGT table_type for the LTST to value 0x0006.
A Recommended Practice for the Data Broadcast Standard is also available.
A/91: Implementation Guidelines for the Data Broadcast Standard
10 June 2001, Download PDF File
This document provides a set of guidelines for the use and implementation of the ATSC Data Broadcast Standard. As such, they facilitate the efficient and reliable implementation of data broadcast services. The information contained herein applies to data service providers as the primary entity that assembles the elements of each data channel. It also applies to broadcasters, network operators, and infrastructure manufacturers. The rules are specified in the form of constraints on the data broadcast implementation. |
