Abstract

Lots of ideas, large and small, general and detailed, regarding a video communication system (“TV communication” was Sony Japan’s term) implemented as a part of a set of wireless handheld TVs (devices in a form factor similar to a tablet PC, intended to receive media (video+audio) streamed from a central base – called “media palettes” or “MPs” in the attached document). The product was intended to be primarily a TV system, and the TV communication portion was dropped for political reasons. However, a significant amount of effort was put forth into figuring out how “TV Communication” should work on both an intra-house (from one room to another) and inter-house basis. The product was intended to be SIP (Session Initiation Protocol)-based, and thus there are SIP references in the attached document, but nothing about the system (particularly the intra-house part) is SIP-dependent in any way.

Invention Disclosure:

Some of the functionality described in the enclosed document was implemented, but much of it was not done before the project was shelved for political reasons. 

Although the invention is written in terms of a video (+audio) communication system, much of it’s other possible uses would also apply to a strictly audio system (which might be much like the multi-handset systems common on the market today, except that they lack some of the nice features described in this document, which seems to imply that there might be patentable material w.r.t. strictly audio phones as well.

A video-based communication system is of particular interest to the (ASL-using) deaf community, and while there have been lots of attempts at video phones, video intercom systems are much less common but could be quite valuable to a family that uses ASL significantly (and has a large enough house for a video intercom to be useful).  Some research should be done to characterize the available market here.
