Re: Standardize Buttons For TV-Web Remotes?

Hi Doug,

In regard to your request for input on key events (both remote control and
keyboard) for television, and in consultation with Mark Vickers (Comcast)
and Bob Lund (Cable Laboratories), we have prepared a table of "Virtual Key
Identifiers for Television Input" based on three industry standards:

   - OCAP, Open Cable Application Platform (a.k.a. *tru2way*)
   - CEA-2014, Web-based Protocol and Framework for Remote User Interface on
   UPnPTM Networks and the Internet (Web4CE)
   - ATSC A/100-2, DTV Application Software Environment Level 1 (DASE-1) P
   art 2: Declarative Applications and Environment

The attached table includes the full set of virtual key identifiers defined
for use with these standards. In addition, certain of these identifiers are
designated as being included in the minimum support provided by a device
that implements one of these cited standards.

If there are any follow-up questions, please let me know.
