Bob, I was again accused of being 'you' over at AVS Forum because I asked what is the difference between the front end of a 8-VSB tuner and the front end of a COFDM tuner. You keep saying it is cheaper to make a COFDM tuner, but with 8-VSB receiver chips priced so low ($8.), how can that be? A COFDM HDTV receiver will need a scaler and the same up-front components as a 8-VSB receiver,...right? Also you seem to be comparing the cost of USA 1080i/720p capable receivers with UK's meager 600 line capable receivers. Isn't some of the price difference due to the fact that one is high definition and the other is not? IB (not Bob Miller - laughs!) http://www.angliac.com/newsarchive/8...rticle_id=1700 The latest single chip COFDM from STMicroelectronics is $4.50 And then you have IP cost of at least $6 for 8-VSB compared to 60 Cents for COFDM. After they mark up these differing cost and factor in real market size, that is what they can realistically sell, you have a pretty wide price differential. We have documented a $3.50 price difference for the chip and a $5.40 IP cost difference which totals $8.90. Mark that up a couple times and you have real money.Especially when you are talking about under $100 receivers. Take out marketing and sales cost of at least 50% and where do you hide an $8.90 difference after a 100% markup? Both have similar HD cost so where ever you end up there is still a major difference. And then of course I would add on mucho additional antenna cost for 8-VSB. Time, aggravation and money all add to the cost of 8-VSB. Basically 8-VSB was designed for broadcasters to lower their cost with the thought in mind that viewers would never use OTA much so why worry about what it would cost them. And it is going that way. The only fly in ointment of this whole plan is that other countries actually came up with a modulation that works real well for the viewer, the designers were from the beginning thinking about the viewer and their cost.

snip quotes You don't know if your particularly interested in watching TV over the Internet because you don't know what the offering will be or what the experience will be like. If an Internet feed replaces cable and satellite, then I'll embrace it, assuming that they don't try to overcharge like cable and satellite. I'm not willing to pay for any programming that includes commercials. You may not like the idea of watching TV on your cell phone but the fact that a cell phone or other such small device can receive the DTV signal with an antenna one inch long is what is important. Using such small device you will be able to watch DTV on any size screen you want anywhere you want including in your living room which is the only place you want to watch it I assume from your post. Your not open to any new idea what-so-ever no matter how much easier or cheaper it might be. You're selling the sizzle; I want to see the steak. Point me to a theoretical comparison of COFDM vs 8-VSB. I do understand that you have an uphill battle to fight, being a lone voice crying in the wilderness. You are just hog tied to what you know right now and no one can change your mind about anything ever. Did I paint the picture right? No. I don't really care how it's done, as long as it works. I haven't read enough theory about COFDM or 8-VSB to choose, and so far the FCC hasn't asked for my opinion. I'm just saying that unless TV programming is suddenly going to get a lot more intelligent (which I doubt) or the Internet is going to take over, OTA needs to be viable. And I am sure you are not the only one like that or who feels that way. Bob Miller |
"OTA needs to be viable"
It will be once they cut off analog transmission. Most Americans just don't take digital OTA seriously now, but it will be as serious as a heart attack when they unplug analog. I think even LG will then reconsider their departure from making OTA tuners. IB |
"We have documented a $3.50 price difference for the chip and a $5.40
IP" I don't know what you mean by "IP", but you are comparing the cost of a standard definition COFDM receiver chip with a high definition 8-VSB chip. Europe does not have OTA HD, so your comparison is false. Then you talk about antenna costs, but in your own tests the 5th generation LG chip did best with a simple loop antenna, which can be had on the Web for as little as $.29 each at SJGreatDeals.com. Chips are made now with a 90 nanometer process and will soon go down to 65 nanometers. They will only get smaller and cheaper. I do not see a significant long term cost benefit. Also didn't South Korea recently pick 8-VSB over COFDM as their transmission standard? They must have all the facts, yet they picked 8-VSB. Why? You always say how lucky the British are to have their TV system, but in about 3 minutes I am going to watch DESPERATE HOUSEWIVES in 720p. Can they do that in London for free OTA? I have been enjoying FREE HDTV for almost a year now, and for most Europeans HDTV is still a pipe dream. IB |

OTA needs to be viable, I agree. It is not viable today with 8-VSB and over a very short period of time it will become far less viable. Bob Miller |

"Yeah I got my power arc aerial from there. it needs 2 batteries once in a blue moon (use some good duracells) it lives ontop of my wardrobe and is very happily picking up all muxes. I'm abt 30 miles from sutton coldfield" Snip... The original AV forum poster doesn't mention in which direction he located from Sutton Coldfield; as there are several repeaters deployed in and around the SC area. (Many of them well within a 30 mile radius, I.E. The AV forum poster could be right next to a repeater, but our resident COFDM Troll would never tell you about that tidbit of info). I assume he knows wherefrom he gets his signal. He could easily be in a direction from Sutton Coldfield that has no repeater. Here is a map of transmitter sites. http://www.wolfbane.com/articles/ukdmap2.htm Judging by my recent research in thed SC area.. I would say the map quoted by your link is incomplete. (I.E. It's missing several transmission towers). Here is a partial MAP of DTV retransmission towers within 56 miles of Sutton Coldfield.. Note: Each tower transmits roughly the same programming. http://www.kswindells.34sp.com/freev...meNGR=SK113003 Well according to your map I was wrong. I thought there was three repeaters within 30 miles of Sutton Coldfield but there are only two. In your post above you say there are "Many of them well within a 30 mile radius". The only two I can see on your map are Brierley Hill: 24.6 km : 233' and Bromsgrove: 31.9 km : 211', both to the South West. Soo.. And several of them are just outside of 30 mile range(48.3km).. 29.. Fenton.. 49.5km 77.. The Wrekin 49.1 km 78.. The Wrekin B 49.1 km Still speaks to COFDM's problem.. @ 30 to 31 Miles it already needs repeaters to function correctly. As for the rest of your post .. snippy... Comparing apples to oranges.. (non-contigous(UK-COFDM) verses contiguous(US-8VSB) The UK's OTA COFDM coverage is spotty as best. No contiguous coverage. B.T.W.. The UK has a one time payment (150 pounds, no monthly charges) satellite service to fill in the transmission gaps. Note: Sat users still have to pay the UK's annual TV tax. |

Of course bob completely ignores standard practices. Purchased IP does not get marked up the same way as purchased built goods. He keeps inflating the IP costs to defend the indefensible. Even LG told him, and he quoted them, that the modulation scheme had very little impact on price when compared to the HD decoding section. -- Matthew I'm a contractor. If you want an opinion, I'll sell you one. Which one do you want? |
