My question on the PSIP copyright issue was really exploring the possibility of a P2P PSIP sharing application. With a large number of folks participating to get a relatively small amount of data it would seem easy to keep a large shared database updated, if no legal hassles existed.

The problem with using PSIP is that you either need a dual tuner card/stb or must put up with losing your picture every so often as the ATSC tuner scans all the available OTA channels for EPG information. Tuners could do the channel scanning/guide harvesting while the STB is "off", but if the box is never turned "off" it would never have the opportunity to refresh the "master" EPG. Further, only 12 hours of EPG data are mandated by A/65, so a 2 AM channel scan may not cover the flowing day's prime time line up.Of course, that does not address those cases where antenna orientation is critical to reception, and any sort of market wide EPG scan would fail for certain channels. Internet based guides are all inclusive, can be read without interrupting the viewing or recording of an ATSC channel, and provides uniform content from station to station in a market.At one point very early in the ATSC process, it was suggested that PBS stations (presumably being 'neutral' in the ratings wars) would carry program information for all OTA stations in the market, easing the task of OTA viewers keeping a current and complete program guide. Unfortunately that was never implemented, and I'm not sure that is even possible today given the way A/65C is worded.John ----- Original Message ----- From: "Tom Barry" <trbarry@xxxxxxxxxxx>I think my MyHD card does use PSIP info, not sure about the F3Q. I'm never sure where the info comes from because I'm using the CW EPG program and I think that blends guide info with whatever the MyHD program gets from whatever sources. And most of my timer recording are on QAM cable so I don't think PSIP applies there.On my Fusion card I can schedule with TitanTv but mostly use it for fixed repeating timer recordings with no guide info.Is PSIP not copyrighted? That is, if I take it off the air can I legally share it with others?- Tom---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways:- Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
