US (ATSC) Data Broadcasting Standard

• Targetd only at terrestrial (vs. DVB trying to
  address sat. cable)
• Approach
• specify several profiles optimized for specific
  likely uses
• leverage existing standards (eg. DSM-CC from
  MPEG, HTML Java from computer industry)
• strive for maximum compatibility w/DVB
• Issues
• slow process
• confusion over data vs. data for EPG vs.
  data for interactivity
• getting better because forward looking content
  providers feel the need for a solution
• See the S13 documents for LOTS more detail

Standards for Data Broadcasting

• What needs to be standardized (by Broadcast
  industry)
• labeling addressing of data payload
• sizes duration of Data items
• What should be left alone (to market or other
  standards groups)
• data specific formats (dont reinvent HTML, JAVA,
  OS)
• receiver price/performance/capability
• priority of business models
