There's an interesting timing dilemma here. The coupons are good for only 90 days, we'd like to get them before they run out, but we'd also like to maximize product availability and selection. How many of the approved boxes are currently available? None. |

I wouldn't think that it needs one, its like just daisy chaining something to your tv.

The box includes the necessary digital tuner to receive over the air channels. The remote would operate the tuner. No, I get that that is what people would use the remote for, to use the tuner. But what I was wondering is why is the tech needed for a separate remote? I had thought that the the tuner would work like this. On your normal tv, you click to local channel 2, and your tv goes to the source, the antenna. Now the tuner looks for your locale channel 2 digital feed, and passes that through to your tv. I guess the way it is actually going to work is as if you had a really separated unit, like a VCR or DVR that you added to your entertainment system. It just seems like more work than it needed to do to work. I'm just trying to think for the lowest common denominator implementation. -- "... respect, all good works are not done by only good folk.

But what I was wondering is why is the tech needed for a separate remote? Even if every infrared remote receiver on a device were identical, each manufacturer or type of product (or even sometimes model of product) uses a different set of codes to send the command. The set-top box with digital tuner and converter will be a lot newer than the tv, so its remote couldn't possibly know the codes to send. Even if it did, how would it instruct the digital tuner to tune to a subchannel? For that, one has to enter a decimal point. I had thought that the the tuner would work like this. On your normal tv, you click to local channel 2, and your tv goes to the source, the antenna. If the new box is hooked up through the coaxial cable 75 ohm VHF antenna jack on the back of the tv, then you'll need an A-B switch to choose the antenna with the tv's tuner, or to receive output from the new box (probably on channel 3). Now the tuner looks for your locale channel 2 digital feed, and passes that through to your tv. I agree. That would be an extremely useful feature. Unfortunately, I've never heard of a tv on the market with such circuitry to accomplish that. If I can tune in the same channel from a variety of inputs, I'd love to tell my tv that over-the-air Channel 2 is available via antenna, or via cable channel N, or satelite channel M, and to choose whichever source offers the strongest signal and not currently tuned to something else or feeding a recording device. It would require a lot of effort on the consumer's part to enter all that data into the tv's channel memory. Probably not gonna happen... I guess the way it is actually going to work is as if you had a really separated unit, like a VCR or DVR that you added to your entertainment system. Yes. |

There was one UHF TV station that absolutely would not come in unless my roommate had his locker door half-open. Go figure. It never occurred to me that dirty laundry placed strategically around the room could improve reception. No, no! He didn't have to tip it over -- just swing the door wide! ;-)) |

(The box has a selector switch for the display type. I'm a "480i.") Is your tv new enough to accept progressive input? Does the converter do progressive output? If it's called ColorStream or as inputs for a connection via composite video cables, it's progressive. See if you notice a slight improvement at 480p. The converter (Samsung SIR-T151) will output 480p but the Sony TV (KV35V35, I think) , vintage mid-90's has no progressive inputs. I'm happy with its picture but can see signs of aging, like small text that's marginally readable -- hard to tell 6's from 8's on some of the scrolls at the bottom. When it has a real maintenance problem, it's going away. (Yeah, I'm clever enough to GIVE it a maintenance problem, just not evil enough.) "Sal" |

A cheap ATSC tuner for your computer is so much better than a VCR. If you have enough money for the computer to write this on, you shouldn't need a government handout for TV. Or are you entitled? No, not everyone is eligible. If have any pay TV service, you household is not eligible, even if you have TV's without a tuner not connected to them. Your household has to be free of any pay service to be eligible for any coupons. Crossposting removed. Incorrect Only coupons issued under the second funding package are limited to households with no alternate signal sources. The first batch of funding doesn't have the antenna reception exclusive limitation. |

"Patrick Joseph Mc Namara" wrote in message ... snip I'm in an area where we can pick up signals across the Lake Ontario. Sometimes they're strong and fairly clear, other times they barely come in. It depends much upon the weather over the lake. I've only tried it with analogue so I don't know how good the digital would be. Signal propagation is weird, at times. I never specifically tried for really long-distance TV reception, but have experienced it. In Norfolk VA, a VHF station came in well enough from Buffalo NY that we sat and watched a movie. (Yes, good antenna/rotor on a mast) Other times, we had a hard time with stations in Washington DC. Because they both use the same set of frequencies, digital is not different from analog, except that digital requires less power for equivalent istance -- and that's one of the advantages cited for the change-over. It has to do with the signal-to-noise ratio (SNR). Analog needs about 40 dB SNR (subject to debate among experts) for a noise-free picture. Digital will usually do nicely with 20 dB, often a bit less. I think the theory is about 16.5 dB, which may not be realizable in the real world. All of which means that if you can get a decent signal from city "A" on analog, their digital equivalents (assuming full licensed power) will also work for you. Not to turn this into a lecture, but if you have ghosts on your pictures now, from nearby hills, buildings or the town water tower, your success with digital is less certain. A better antenna often helps. |

The channel changing happens on your tv/remote, and the convertor just lets you additional channels on the same tv/remote. Converting a digital video stream to analog isn't a trivial process. It would take a powerful and therefore EXPENSIVE computer to simultaneously convert all the multiple sub channels available in most areas and modulate all of them on separate analog closed circuit RF channels. Most of the converters will only handle a single digital sub channel at a time. The converter WILL need to have its own circuitry to change which channel you want to watch. Of course the requirement for the manufacturer to include a remote AND its batteries to make the converter eligible for the federal coupon program might be of some influence. |

The channel changing happens on your tv/remote, and the convertor just lets you additional channels on the same tv/remote. No, you need to change the channels on the converter box. After the analog shutdown, and assuming a signal source of an antenna, the only source of signal for the TV is the converter box, either by a baseband video connection (e.g. RCA plugs, S-video, component video) or by RF that the converter box provides for *ONE* channel (probably you get a choice of analog channel 3 or analog channel 4). Changing the channel on the TV gets you static. A converter box does *NOT* convert a dozen or two digital stations to analog simultaneously and put them together into an RF signal so that an analog TV can select the channel. You could assemble one with a dozen or so converter boxes and an equal number of RF modulators, but it would be expensive and give poor signal quality. If you have an old analog VCR or analog DVR, it used to be able to change the channel on its own turner. It probably can't change the channel on the converter box (unless it's got an IR blaster and the right codes). You now have a time-recorder not a time-and-channel-recorder. This sucks. |
