[1] Various types of content can be
cross-linked using MediaLocator (see Metadata specification S-3.) In TVA
Current Release, the program metadata does not contain a CRID for cross-linking
to other programs.
[2] Entire programs can be
overwritten, but segments of programs cannot be overwritten in current
release
[3]
Collection of information regarding viewer usage of content is enabled in TVA
Release 1A. The method of accessing the information by the service provider is
not specified in Release 1A. This may be an implementation issue.
[4] The RMP specification
currently supports audio video content primarily with data content protection
part of current work |
These
specifications will enable search, select, acquire and rightful use of
content on local and/or remote personal storage systems from both broadcast
and online services. These features require firm standardization.
There
will be further TV-Anytime phases published and Business Models for
Phase 2 are currently being defined to include
Private and public domains, portable recordable media, super distribution
(legal sharing of content between consumers), peripheral device support and
mobile devices, amongst others.
