Cross-Industry Alliance
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 (don’t reinvent HTML, JAVA, OS…)
receiver price/performance/capability
priority of business models
