John Barkley, M A. Dolan, M Koo, Andrew McCaffrey, Leonard E. Gebase, Murugiah P. Souppaya


The Declarative Data Essence (DDE) Ad-hoc Group of the D27 Technical Committee of the Society for Motion Picture and Television Engineers [SMPTE] is developing ITV standards that provide basic functionality for ITV and represent current practice, known collectively as DDE-1. The Advanced Television Enhancement Forum [ATVEF] specification was the starting point for this DDE-1 effort. The T3/S17 Specialist Group within the Advanced Television Standards Committee [ATSC] is developing the DTV Application Software Environment (DASE) standard for the next generation of ITV. This paper describes the SMPTE DDE-1 specifications and compares DDE-1 to DASE. In addition, this paper describes the functionality specified within DDE-1 and DASE that enable content developers to present and manage ITV applications.
