Data Broadcast Specialist Group

This specialist group will define the mechanisms for serving the needs of data broadcast applications utilizing the ATSC digital broadcast as a delivery medium. This will include both program-related and non-program-related DTV applications. Specifically, TSG/S13 will define a method or methods for using ATSC digital broadcast to transport data streams, data files, and executable code. The group will also address other generic requirements imposed by these applications, for example low latency needs of some interactive applications, synchronization with video/audio programming, etc. This scope includes:

  • Developing data-service-specific constraints and extensions to the current version of ISO/IEC13818-1 (MPEG-2 Systems);
  • Developing constraints and extensions to the current version of ISO/IEC13818-6 (DSM-CC);
  • Developing one or more transport encapsulations, signaling synchronization, and announcement methods specific to data streams as defined by the current version of CEA-708;
  • Developing one or more transport encapsulations, signaling and announcement methods specific to video or audio metadata;
  • Developing data-service-specific metadata and its transport means that is applicable to future as well as current programming;
  • Preparing guidelines and recommendations for effective use of data service standards; and
  • Maintaining all published documents.
