RickMerrill wrote: Is SFN (single freq network) really relevant now that 8VSB yields several subchannels for each station? Does OTA ATSC use program MPEG or transport MPEG? SFN has nothing to do with sub channels. With SFN a broadcaster can put multiple transmitters on the same frequency and the receiver will select the strongest signal for receptionists. This requires the broadcast station to lock the multiple transmitters together so the receiver knows it is the same material. This has been tried in New York City to fill in where signals are weak. The test has been a success and ends up being transparent to end users. ATSC uses MPEG2 transport streams, program streams are used for DVDs. Regards, Bill Cohn - N9MHT |

And I got a free car by buying a very expensive key. Oh really? Was the key previously sold at the same price without the car? That's the point. If the Internet package is $39/month, and they add basic cable to the package for the same $39/month, then the added basic cable is indeed free. [Or they lowered the price of the Internet package to...say... $29/month and are charging $10/month for the basic cable.] |

Very confused by your "point". Moving OTA viewers to cable where they are already getting paid per subscriber is a "positive move" in my book. That is the future for any successful broadcaster as far as I can tell their plans. You're easily confused. By using the horrible (according to you) 8VSB modulation which nobody (according to you) can receive, the stations have eliminated a free alternative to cable for many viewers, and in doing so eliminated any incentive cable had to pay them for their signal. Cable can now say "If you want ANYBODY to see your programming - and your advertisements - we'll carry them, but not pay for them." Do I need to draw you a picture? Logic impaired? Your reputation is well earned. You're a loon. Let me see if I can draw you a picture. The broadcaster delivers his free content via 8-VSB in glorious SD and MPEG2. At the same time he delivers the same content via cable for a subscriber fee in HD and threatens to deliver or delivers the same content in HD via MPEG4 and M/H for a subscriber fee. Analog reception works the exact same way, except for the modulation being used for analog, and that there is no MPEG-type codec being used at the receiving end of an analog tuner. That is, I have a choice of a watchable analog picture but it may have constant snow or ghosts, or I could subscribe to analog cable and get a better picture than I can get over the air. I also do not receive all possible analog OTA channels. So for those channels that I cannot even receive OTA with analog reception, I have the choice of not viewing those channels, or subscribing to a basic cable package that includes all the basic networks. In all cases, if I subscribe to analog cable, then I can view all of those channels without any snow or ghosts. Consider that the "high definition" of analog, if you will. Now, that analog reception choice becomes moot after the DTV transition date, but then I still have the choice of OTA DTV or subscribing to digital cable. (Yeah, I know, I can subscribe to digital cable even now, but I'm taking that option out of this discussion to keep the discussion a bit more simple.) Currently, the few channels I receive with OTA DTV are more than good enough, since I don't spend the majority of each day watching TV anyway. So the real problem with 8VSB is--as has been mentioned in many previous discussions--the dynamic multipath issues that result in audio dropouts, macroblock picture artifacts, frame dropping, picture smearing, picture freeze, and the eventual black screen with a No Signal indicator. Fixing the dynamic multipath issues effectively fixes 8VSB so that it is more than good enough for OTA reception, with a picture and sound that is, in many ways, superior to even a standard defintion picture over analog cable just using a DTV converter box. (Some converter boxes do have audio bugs, but that is a converter box issue rather than an actual OTA DTV issue.) Those with HD TV sets are also more than capable of viewing an even better picture, provided that they are also viewing high definition content for the best possible picture. The customer now has a choice. He can receive his CBS ala carte in HD OTA mobile or fixed for a fee or free in SD via 8-VSB. But the current DTV situation is that if the customer has an HD TV set with an ATSC tuner that receives OTA DTV (using 8-VSB) and is able to receive the CBS DTV signal, the customer can receive CBS in HD for free without the need for a cable subscription because CBS is apparently broadcasting in HD even before the DTV transition date. The MPEG2 vs. MPEG4 codec argument is an entirely different discussion, involving picture quality based on bitrates and framerates in part, but also consider if MPEG2 was more than good enough for DVD movies, then it is probably going to be good enough for most mainstream OTA DTV TV viewers that aren't necessarily interested in the technical details such as codec, framerate, or bitrate (among any other technical details). Further discussion is welcome. |

Once the signal gets very weak then it will get into breakup. I get excellent results from a digital channel with less than half the power of the analog transmitter at the same location, and the analog signal is too weak to watch -- just barely visible. They are on channels 50 and 54, so frequency is similar. Yes, when digital goes, it doesn't have a lot of loss from perfect to pretty bad, but the news article writer didn't understand that digital will still be perfect when analog has become really bad. Alan YMMV: in remote/rural areas the digital signal may be so poor that while a 20% signal may look great, below that you may get pixelation at random and loss of sound which is way, way worse than listening to or watching a poor analog. My point is that the poor analog, on the same channel, with the same power level, will probably not be there at all. People are frequently comparing full power VHF stations with UHF digital stations at a lot lower power. In comparing KTEH analog (ch 54, 661 kW) and KTEH-DT digital (ch 50, 290 kW), we get good reception from the digital channel, but the more powerful analog channel is pretty much unwatchable by any standard. With the same power and similar channel assignment, digital goes a lot farther than the low power UHF that some folks are working with. Is it possible that after the transition TV stations may increase the power of their digital transmission? Some of them are running reduced power, so we have to expect them to eventually bring it up to their full power. Others will move back to VHF channels, or lower in UHF, which could also help their performance. Alan |

You make it sound as if the "transitional date" was the date of transition. NOT SO! The transition has been an ongoing process, was supposed to be anyway, since 1998. It was suggested back then that the transition would be so far DONE, OVER, FINISHED that by 2006 we could turn off all analog transmitters. That was the LAW, that was the plan until it DIDN"T WORK. No one was transitioning, no one was buying receivers, broadcasters were not advertising, retailers were not retailing so they DELAYED it three years till 2009, set up a MANDATE to force the inclusion of receivers into all TV sets and decided to subsidize converter boxes for the truly last minute analog holdouts. Most other countries with decent modulations have seen a smooth and ever more successful transition starting from the their various dates of inception. Most other countries have seen a pattern where early adopters told their family and friends about the benefits of OTA DTV and helped propel the FREE unsubsidized sale of receivers and integrated DTV sets to ever higher numbers quarter after quarter. Early adopters had few problems and found that DTV worked out of the box with simple antennas. In the US the opposite happened. The few early adopters told their friends and family how hard OTA DTV was and how smart they were at getting it to work. They bought each new "improved" receiver as it was introduced and built 50' rotorized antennas and bragged about it to whoever would listen. Most average Joe's were turned off in the US. Most other countries started their transitions far after we did but are far ahead of us today. In these countries the END of the transition will be when a very high percentage of homes have working OTA DTV receivers that are being used not DTV sets that have MANDATED OTA receivers that they are not even aware of. The UK started in 2004 and has 72% of all homes with at least one OTA DTV receiver. France started in 2005, has only recently achieved coverage of 88% yet already has 42% of homes with OTA DTV. The US has virtually had 100% coverage for many years and offers the super added incentive of FREE HD and what percentage of US homes are using OTA DTV today? Would anyone dare say 5%??? "Digital penetration reaches 56% According to recent research by the NPA Conseil on behalf of TDF, 56% of French homes now watch digital TV via DTT, DTH, IPTV or cable. DTT is the most popular mode with 42% watching terrestrially, most penetration being in the eastern part of the country. Many people still watch some analogue TV with 45.9% of the population having at least one analogue TV set while 28.7% still watch analogue TV on the primary set. The research also showed that 23.2% of all French people now have an HD Ready or Full HD screen in their homes. Source: Broadband TV News Item added: 11th August 2008" http://www.dvb.org/about_dvb/dvb_worldwide/france/ Australia started in 2001 with little coverage. They have 42% of homes relying on OTA DTV today. ACMA publish latest report on free-to-air TV The Australian Communications and Media Authority has just published a new report on the adoption of Digital Television in Australia which puts the proportion of those watching terrestrial digital television at 42%. When the number of viewers subscribing to digital television services are combined with those watching terrestrial digital television the proportion watching free-to-view services increases to 52%. The highest adoption rates for DTV where in Mildura (70.3%) and Tasmania (64%) and the lowest in South Australia (37.1%) and Queensland (37.2%) The full media bulletin can be accessed by clicking on the following link: ACMA website Item added: 15th April 2008 Germany is a different story. Their transition is over. No analog as of November. Only 11.1% use OTA DTV. This is a heavily cabled country maybe even more so that the US. Their OTA may not be competitive with cable programming wise. I don't know. But what is interesting is that their mobile DVB-H may be failing since one operator is handing in their license. The interesting part though is that cell phones and other receive devices are being sold to receive the standard DTV OTA, DVB-T. Even though DVB-T is not set up for mobile in Germany it is being USED that way and I expect it to grow very fast. When and how Germany now transitions to DVB-T2 and OTA DTV becomes even more efficient and more receivable mobile, because when they do this transition it will be all about mobile, is the question. And when they do the quantity and ease of reception ubiquitously will make OTA in Germany a competitor to cable IMO. And I am not saying that OTA DVB-T could not be a major mobile ubiquitous competitor to cable today, it is just that they have set the parameters and built the network for fixed reception so far. BUT it works pretty well mobile and portable anyway so the logical competitive forces will drive it to be used more mobile, to change the modulation to DVB-T2, to change the parameters, to build out the network more. Till they have what I propose, a ubiquitous DTV OTA that can be received anywhere at any speed and deliver lots of bits in many resolutions. The MPEG2 vs. MPEG4 codec argument is an entirely different discussion, involving picture quality based on bitrates and framerates in part, but also consider if MPEG2 was more than good enough for DVD movies, then it is probably going to be good enough for most mainstream OTA DTV TV viewers that aren't necessarily interested in the technical details such as codec, framerate, or bitrate (among any other technical details). Further discussion is welcome. MPEG2 vs. MPEG4 argument is not so much about quality as quantity. The more quantity the higher the value of the spectrum to everyone. The more the OTA spectrum can compete with cable for instance. The more a broadcaster can deliver. OTA viewers are NOT interested in ANY of the technical aspects. They are interested in getting such things as HD and with MPEG2 there is some problem with quality especially with 1080i. EVEN using the entire channel, all the bits possible and with mobile M/H lots and lots of those bits are going to be robbed from 1080i or even 720P, not so good. If you used a better modulation and MPEG4 you do not have to SEGMENT off a whole lot of bits for mobile. You can use MPEG4 with ALL the bits and you can deliver more content with FEWER bits, half as many, later 1/3 or even 1/4th as many as MPEG4 matures. Today with 8-VSB and M/H you have your channel SEGMENTED into two distinct parts. One for 8-VSB/MPEG2 receivable with all current and legacy receivers and one receivable by NEW M/H/MPEG4 receivers in cell phones for instance or laptops. Proponents of this garbage can falsely claim that this system is backward compatible with current receivers since current receivers could receive an M/H mobile broadcast which is true. BUT ONLY IF THE BROADCAST IS IN MPEG2. And NO broadcaster is going to use M/H with MPEG2. And if they did they would also have to use A LOT MORE BITS with MPEG2 and M/H to do even one mobile program and that would IMPERIL HD on the other part even more. So the proponents of M/H are lieing to us while telling the literal truth. They have to tell the literal truth as a smoke screen because many would be outraged if they realized that the SACROSANCT RULE of the digital transition that NO change can happen that makes any legacy receiver obsolete can happen. That is the DAM against any possible consideration of changing modulations or codecs. The LAW against making any legacy receiver obsolete. But what they are doing is doing just that. Legacy receivers and all current receivers including the converter boxes will not be able to receive M/H/MPEG4. Legacy receivers and all current receivers including the converter boxes will not be able to take advantage of the better receive capabilities of M/H even if broadcasters were to use MPEG2 with M/H instead of MPEG4. It is all a lie. M/H breaks the rule that says all legacy receivers must work with what broadcasters are broadcasting. As broadcasters use more and more of their channel for mobile they will break this rule just that much more. The US might as well consider changing modulation and codec now. The sooner the better. And may the best modulation and codec win whether it is an advanced form of 8-VSB or an advanced form of the Chinese standard DMBT. Bob Miller |

You want to change it to MPEG4 over might. The technology was not available ten years ago that is why we have MPEG2. Very few people have actually consciously purchased an 8-VSB receiver. That is most who have one don't even know it. Of those who know they have one very few have tried to use it or are using it. After 10 years of trying where is "here"? Nowhere! There was good advanced codec technology available in 2000 when the FCC reviewed the US modulation and considered changing it. We proposed two things. Allowing another modulation and codec to be used and making the specifications for receivers to include an upgrade path for more advanced codecs. If this had been done all receivers that have been sold could be, today, upgraded to MPEG4 or other codecs. They would have cost bit more but would allow for TRUE HD even 1080P with MPEG4 now. Stop comparing our market with Europe that has not had the cable penetration we have had in the US. Germany has a high cable penetration at 52% and growing and satellite of 42% or a total of 94.5% while the US is at 61.3% cable and falling and 28.4% satellite for a total of 89.8%. Why deny US viewers a decent OTA DTV modulation because Europe is slightly different than the US? In the UK 88.5% of homes have digital TV with 53% choosing satellite. I think it is valid to compare. To ask viewers in the US if they would like to have what consumers in countries like France and the UK have today. Especially with this economy maybe some would like to drop cable for something like Freeview with a whole bunch of free DTV channels plus digital radio all free. And both France and the UK will have OTA HD, have HD via satellite. The life expectancy of a TV set in the US is about 15 years. No need to replace a DTV just because it has an 8-VSB receiver. You can add a small inexpensive receiver to any TV for other modulations and codecs. Bob Miller Regards, Bill Cohn |
