Enhanced Television raises a host of new intellectual property issues, with more questions than answers at this early stage. Consider the possible "IP" issues for stations with each type of enhancement from the recipe book. APPETIZERS PVR Record Triggers Minor Issue - Ideally, this technique currently propriety to TiVo would be a universal standard for all PVR devices. VOD Major Issue - As VOD systems become more commonplace, there is the potential for national producers and networks to bypass local stations. DIGITAL DINNERS DTV Audio No Issues DTV EPG Major Issue? - Gemstar/TV Guide hold many key patents for Electronic Program Guide features. Ongoing litigation may result in DTV receivers having limited EPG features. Digital Cable EPG Major Issue? - Broadcasters are at the mercy of the cable system with regard to the channel numbers assigned to their DTV services. (It WILL NOT match the DTV major-minor channel numbering.) The cable system also has control over the order and appearance of the stations programming in the cable EPG. DTV PSIP Minor Issue - There is no law that prohibits a broadcaster from using a virtual channel number other than their own. If two broadcasters want the same number, there is no way to resolve the dispute. Widescreen Production No Issues TV DINNERS Walled Garden Major Issue - Who has the right to control ad-banners that appear above the walled garden content? Will the content developer be prohibited from including ads within their content? ATVEF Transport A Major Issue - Does the common practice of re-purposing code from web pages also apply to code for enhancements? ATVEF Transport B Unknown Issues PC DINNERS PC Synchronous Unknown Issues Streaming Major Issue - As necessary broadband connections become more commonplace, there is the potential for national producers and networks to bypass local stations. DESSERTS Localize ATVEF Major Issue - Stations and producers can easily come into conflict over what local enhancements can be added to national programs. Transmit Transport B Major Issue - Does the producer have the right to specify the bandwidth that must be available for the enhancement data-broadcast? This could be a problem for stations that have insufficient remaining bandwidth. TEST KITCHEN DASE Issues likely similar to ATVEF.
