First, the background. The sainted furst customer of my PSIP generator is KYES-DT Anchorage, AK, which is controlled by Jeremy Lansman (a legendary community radio pioneer and engineer) and his wife Carol. Jeremy is a home-grown kind of guy. You can do a google search and see quite a few posts about him, including stuff from RalphMag.com, a web site run by his friend and former partner Lorenzo Milam. I haven't talked with Lorenzo in a few decades, but his legend is even bigger than Jeremy's. Some of this is chronicled in Lorenzo's 'Sex and Broadcasting', which only lightly mentions their creation of KFAT (now KPIG-FM and a whole new musical format, Americana.) Jeremy brags about the fact that he put his FSTV DTV station on the air using used equipment bought on Ebay. (However, he couldn't buy a PSIP generator that way, which is how we came to work together.) Jeremy's station is a commercial broadcast station, with network (MyNetworkTV, after the demise of UPN) and and syndicated programming. He has built or assembled everything, except the code in the PSIP generator. He takes non-pathfire programming down from satellite in analog and captures the content to standard-off-the-shelf DVD burners. The disk's MPEG-2 video output is then converted to analog and aired directly. (This will change a bit, I hope, when analog sunsets.) Jeremy doesn't have a caption generator, and isn't required to generate captions, but under the rules he has to pass on captions that are alerady in his syndicated and network programming. This is a bit of an issue between us, since a PSIP generator, to be in-spec, needs to assert the caption_service_descriptor in the presence of captions, and to not transmit it in the absence of captions. Jeremy has no way of detecting captions. But -- thanks be to the MPEG-2 gods -- when he captures analog programming with CEA-608 captions, his setup transmits CEA-608 captions. I also need to mention that his Lucent ATSC encoder puts illegal (due to an extra byte) rc_descriptor into his digital programming (three video/audio and three audio/only) channels. The video/audio channels are also on DirecTV and DishNetwork. Jeremy and I are at different ends of the political spectrum, which makes for lively discussion. He did like my "Empress Pelosi" in a conversation the other night, and when assured that I hadn't first heard it on Rush Limbaugh's show, he asked if he could use it. In that conversation, he mentioned that he was getting come telephone complaints from people that were having trouble recording certain television programs. Of course, if the rc_descriptor were as Bert the dilletantish fool and foil sees it, nobody would ever be able to record any programming, since he will be asserting the rc_descriptor until he gets around to having my PSIP generator generate MPEG-2 PSI as well as PSIP, taking the PSI subsystem of the Lucent out of the stream. Did I mention that EtherGuide Emissary has been operating faultlessly at KYES-DT for more than 62 days in a row, generating reliable PSIP every second, and not skipping even a beat when we upgraded the output to use the new form of the AC-3 descriptor a few weeks back? Anyway, so much for the advertising part of this posting. "That's a CGMS problem," I noted, "but if the distributor is sending the CGMS flags, how do you even record the programs?" "They must be sending it as 'copy-once'", he said, and my DVD copy counts as that first copy. The work-around to this, of course, is for his station to acquire a working caption generator (we've gone round-and-round on this point) and to strip out the CGMS bits (at least for television programs where he can do that pursant to the contract.) There will be hell to pay if anybody transmits syndicated programming to him with CGMS set to "copy never", since he may not be able to burn the content to DVD. So, this is a long-way-around to point out that, unlike Bert, I actually do have experience with diagnosing such issues, and I know for a fact that the rc_descriptor does not prevent the recording of programs, but that the CGMS bits can and are used for that purpose, and that they can exist even if the programming in question was of entirely analog origin.
