Digital Video Recorders

Probably about the same time it hit the US markets, which was around 1974. This doesn't mean that they didn't exist quite awhile before that, but those VCR's were industrial and usually in the 3/4" format.

Sony invented the VHS system and then licensed it to JVC in preference over the Beta format (I bet they ended up regretting that....) and the first consumer machines appeared around June, if I remember correctly.

You can only enhance what has already been recorded. If the information simply isn't recorded, there's not a lot you can do.

A standard color camera may be improved, at the time of recording, by using an infra red light source, to illuminate the subject without it being obvious.

Most (if not all) video cameras are sensitive to infra red.

No. However if you used Nero Burning ROM 8 or 7 Edition you could set the feature to be able to add information. But you will never be able to erase and recopy.

You can play a recorded show from one DVR but you cannot play it on another DVR. A DVR works similar to a computer that is not linked to any other computer or the internet. You may record something on a single DVR and the television it is linked to will save the show you want to watch at the particular time it plays. Then you will be able to go back at a later more convenient time and watch the show as you like. But if you two DVRS' in a house, one upstairs and the other downstairs, you can only play recorded shows on the DVR that you recorded the show on.

No, not if the old tapes are in analog rather than digital format. See the review of this DCC at http://www.easycamcorders.com/content/Quick-Review-Camcorder-Sony-DCR-TRV280.htm: "How ... am I going to watch those [old analog] tapes?... Not here, you re not. The DCR-TRV280 does not read analog 8mm. For that, you need to step up to the DCR-TRV480."

It seems to me to be the cheapest way to get into digital video with a reasonably high quality and versatile camera. No, not if the old tapes are in analog rather than digital format.

Yes you can

You can if you have another device that has a digital tuner plus the ability to convert digital to analoge, such as a set-top box, digital to analoge convert for over the air TV signals, and a DVD disk recorder with a built-in digital tuner.

At 24 frames per second times 60 seconds equals 1440 frames per minute.

Think in terms of ray tracing. Light travels in a straight line in a pinhole camerabecause there is no refracting or reflecting optical element to change the path of the rays of light. The bottom of the film is on the line passing through the pinhole and top of the object. Since all light must pass through the pinhole, that means the top of the object exposes the bottom of the film.

A DVD-R burner, software and a DVD-R disk. The software can be found anywhere for free. The hardware(DVD-R) burner needs to be purchased at a store along with the disk. Once you have installed the hardware and software just place the files on the disk.

Naya hooyathaa wus dont ask me an f question do i look like google to u fool noise up kitty

The possible code numbers for Direct TV remotes for Sony surround sound receivers are:

31058, 31441, 31258, 31759, 30158, 31658, 31858, 30474, 31349, 31558, 31442, 31758, 30168, 31406, 31662, 31759

you'll have to try all of these.

The DVD player was invented in 1996 in Japan, by Sony.

Camera obscura, it was created in early china, the theory was that if you seal a box and it's pitch black in side and you poke a hole the image would be upside down, this came to be true. Then deguerre found out that silver nitrate turns black when you put it in the light, aka how we get film, hope I helped!

There are several, but I would choose degradation of copies as the most obvious.

If you have ever made a photocopy of a photocopy, you will see the evidence of analog degradation - more spots or "noise" on the later copy. The same thing happens with analog recordings - as you make a copy, the "noise" (unwanted parts like hiss, clicks, fuzziness of images, etc.) increases. By the time you have made a copy of a copy of a copy, there will be a noticeable difference in quality from the original version.

== To demagnetize a head, use a commercial demagnitizer. They used to be available at Radio Shack and other suppliers, but they've disappeared pretty much. You can still find them, but you'll have to look around. They're aren't really that expensive, but are difficult to locate because the technology of the tape machine is being displaced more every day. The demagnetizer, or degausser as it is sometimes called, is basically a coil of wire with a ferromagnetic core that extends like a "wand" out of the windings. The coil is connected to a plug, which is simply connected to household power. There is a switch on the unit somewhere. It's press and hold, or spring loaded to off, or the like. You have to hold it down for the unit to come on. Let go and it goes off. The coil works by "sweeping" the head with a changing magnetic field to "scrub" any existing fields that may be impressed on the head off of it. It uses 60 Hertz household AC from the power grid to do this. You plug the unit in the wall, hold it close to the head (the "wand" is usually coated with a soft vinyl coating to protect from damage), and move the unit around. Continue moving the unit around for a few seconds like you're wiping off the head, and then, while keeping the unit energized, start moving the unit back away from the head. That is, you'll be "wiping" the head with the unit held on, wiping continuously as you slowly move away, and then letting go of the switch after you get the wand a few feet away from the head. You're done. You might get an audio shop to do this for a few bucks if you lug the unit in. It will save you buying a degausser. And this isn't something you have to do every few months, even if you use your deck a lot.

It quantizes it into discrete points represented by zeros and ones (digital information). The number of samples must be at least two times the highest frequency component of the analog wave. The number of bits in each sample determines how close the digital information is to the actual value of the analog signal.

Dielectrics is a fancy term for insulators, based on the material used and its efficiancy at a measured range of frequencies. For example, in a coaxial cable, the better it isolates the main frequency from feeding through to the shield, the higher the dielectric value.

For an insulating material dielectric strength and dielectric loss should be respectively

All the software you need comes preinstalled on an iMac.

Good question indeed!

I can't say this for sure, but as far as I know you can not download or record Footytube videos to pc. I watch Footytube videos from time to time but I never saw any button round there that could enable you to save Footytube videos to your hard disk.

It's a shame really, cause I would just love to be able to download a couple of Footytube videos to pc, they have some pretty good compilations if you ask me.

If there really were a way to actually be able to download and convert footytube videos for cell phone I'd be interested to try it too.

Tivo from DirecTV does this. I think the regular Tivo can do this as well.

In Ontario, it is not as long as one party has consented. In short, if you are doing the videotaping and you are a party to the conversation, it is legal. You cannot tape anyone without their consent if you are not a party to the conversation.
