It looks as if that will soon be the new standard and all lower resolutions(except maybe 1080i) will be gone. We need one standard anyway. Man, I wonder what people are to do with their older HDTV's.

Man, I wonder what people are to do with their older HDTV's. 1080I isn't going anywhere for quite a while, around here, there are NO plans for a couple of the stations to do anything more than 720P and the one that does 1080I just bought all new stuff, and isn't about to change anytime soon. So everyone with a 720P/1080I set will still be watching it years from now...maybe decades..

BDK Not to mention the cable companies that have recently invested a whole lot in delivering both 720P and 1080i in 1080i format. Yes, there will be no broadcast 1080/60p any time soon. The bandwidth is just not there. The ATSC format does provide for 1080/24p and 1080/30p broadcasting, but no one has adopted this and I doubt if they ever will as a broadcast format. 1080/60i and 720/60p will remain the OTA broadcast and cable & sat network formats of choice for many years to come. Since most HDTVs are inherently progressive displays (plasma except for ALiS, LCD, DLP, SXRD), all 1080p when applied to display resolution means is that it will display 1920x1080i at full resolution. And will look very good for Blu-Ray (when they fix it) and HD-DVD movies. However, anyone with a TV of 50" or less will be hard pressed to see the difference between a 1366x768 and 1920x1080 screen at normal living room sitting distances. Try it with the new Pioneer Pro-FHD1 1080p plasma with other Pioneer and Panasonic plasmas in the stores. Alan F |

Broadcasters could use this legally after delivering an SD quality program with MPEG2. Of course if we were to allow MPEG4 for that SD program all current receivers would be obsolete which would open the door to switching modulations. What the definition of compatible is for current receivers is becoming comical. If a broadcaster wants they can use as little as 2 Mbps for the SD required MPEG2 program and use the rest of their bandwidth, 17.34 Mbps, for MPEG4 today. IMO that would make all current receivers 88.5% incompatible. Broadcasters could also elect to use A-VSB and if they do they will have to use MPEG4 AVC with it to get even an SD program to fit in this robust segment. At least from the data I have been given. To deliver a robust A-VSB SD program will eliminate the POSSIBILITY of also delivering an HD program in the same 6 MHz. The best of both worlds, no HD and a single robust SD program. They will probably simulcast the same content so you will have two copies of the same SD program one in robust A-VSB form and the other in 8-VSB. Could you possibly think of anything worse? From what I here broadcasters are all excited by the concept of A-VSB. Can't imagine why accept it will give them a slim change, at least in their minds, to stay in business in a world of 8-VSB. So with A-VSB you will have maybe 30% compatibility for all current receivers but no HD. With MPEG-4 but no A-VSB you will have 11.5% compatibility for current receivers and the possibility of HD even 1080/60P on the MPEG4 side but again not receivable by all current receivers. I guess the FCC and Congress are "protecting" as much as 11.5% of the OTA spectrum for 8-VSB and MPEG2, just enough to mess everything up and kill OTA. Bob Miller |

Bob Miller So YOU Bob, want the billions that have already been spent to be discarded and then start over. You know, I read that shoot-out stuff from '99 between 8VSB and COFDM and at that time NEITHER worked well. You will say that it was a faulty COFDM receiver but they KNEW it was a shoot-out and they used the 'faulty' receiver anyway. What I think happened was there is a perception that COFDM requires a larger power output for a given coverage area and that it is less tolerant of co-channel issues. Now I KNOW that it isn't a big deal with 8VSB since channels 59,60,& 61 are DTV in LA and channels 58 and 62 analogs are running as well. I have no problems with any of them. Larger transmitters cost more and use more power. I think the congress was presented with a pair of mediocrities and they chose the less expensive - logical at the time. Expecting everybody to buy all new stuff is just DUMB so live with it. GG |

Bob Miller So YOU Bob, want the billions that have already been spent to be discarded and then start over. What billions would have to be discarded? As to broadcasters they would have to switch out an 8-VSB modulator for a COFDM one. Not that expensive. Broadcasters would do that in a heartbeat if they could. They would love to switch to COFDM. The cost to them would be trivial compared to the cost in bit rate alone that they will suffer when they start using A-VSB. And that bit cost goes on forever. Every day they lose at least 8 Mbps all the time. And the cost of buying an A-VSB modulator will be far higher than that of a COFDM modulator. With COFDM they would maintain a high bit rate and have a robust signal at the same time. As to the cost to early adopters, hard to imagine that buyers of 8-VSB receivers are still considered early adopters after almost nine years, they have been buying the latest 8-VSB receivers offered over and over in the vain attempt to find one that works for years. Some tell of owning 12 and more receivers. And they would line up to buy an LG 5th gen receiver that matched the prototype tested 2 years ago if LG ever decided to make it. They would have to pony up for a new COFDM receiver yes. All of maybe $130 initially for a basic HDTV receiver but one that worked. You know, I read that shoot-out stuff from '99 between 8VSB and COFDM and at that time NEITHER worked well. You will say that it was a faulty COFDM receiver but they KNEW it was a shoot-out and they used the 'faulty' receiver anyway. They? They, the ones controlling the "shootout" were the NAB and MSTV, they were the strongest proponents of 8-VSB. "They" were the enemies of COFDM. "They" went to a great deal of trouble, in secret, to find a "receiver" that would not work. "They" then pretended "they" knew nothing about the problem with this "receiver", namely that is was NOT a receiver. This was a fraud, a fraudulent test, performed by those who wanted a certain outcome. "They" did it in secret. I personally called the engineer who was in charge of finding COFDM receivers and was told that the three I offered were not needed since they had ALL the receivers they needed. "They" had ONE "receiver" that was actually a transmitter monitor specifically set up to accept all interference and meant to be attached, hard wired, directly to a transmitter not be carted around the far field as a receiver. "They" knew exactly what they were doing and that was to participate in a fraudulent charade to discredit COFDM. What I think happened was there is a perception that COFDM requires a larger power output for a given coverage area and that it is less tolerant of co-channel issues. Now I KNOW that it isn't a big deal with 8VSB since channels 59,60,& 61 are DTV in LA and channels 58 and 62 analogs are running as well. I have no problems with any of them. Not a big deal with COFDM either. Co-channel interference is not an issue. Sharp filter technology has long ago made that a non issue. It was a non issue when it was used as a canard to sabotage COFDM in 2001 and the parties knew that. All test of COFDM that have been done in the real world have found that the power differential is a non issue. They can't find it in the real world. Australia was in the 8-VSB camp for years before they did a comprehensive test, in the open, and switched to COFDM. And Australia has lots of big open spaces where coverage is what it is all about. Same with Russia and China, all in the COFDM camp. Well China has a foot in both camps but the market will decide and that means COFDM exclusively. Larger transmitters cost more and use more power. I think the congress was presented with a pair of mediocrities and they chose the less expensive - logical at the time. 8-VSB is far far more expensive. First it has cost nine years of stagnation. Expecting everybody to buy all new stuff is just DUMB so live with it. "Everybody" has not bought 8-VSB. In fact few have. And it is not all new stuff just a receiver. COFDM receivers are very inexpensive. $19 on Ebay, as little as $35 new. An HD COFDM receiver would cost under $100 within six months of it being OKed in the US. Bob Miller GG |

The only thing 1080/24p has a problem with is 60i video. If you had a channel dedicated to film sourced material (filmed TV shows and movies) there shouldn't be a problem with 24p. Even then I don't think deinterlacing 60i to 24p for commercials or the odd program would render an unwatchable mess. I, for one, would like to see a movie channel (HBO, Showtime, Cinemax, TMC) show it's faire in 1080/24p. |
