Digital Video Recorders

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

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.

Most DVD recorders have Audio and video output sockets on the back.

Use the Left and Right audio out and connect to a recorder.

These days most people will want the audio stored digitally.

You can use a patch lead that combines the two RCA connector to a single stereo 3.5mm jack plug, use the jack plug in the mic socket of your computer and record using windows recorder or equivalent.

You can also buy dedicated MP3 recorders that accept analogue inputs, or use a capture card or dongle.

yes

gottem. phsyche!!

babe? or baby?

Gibberish: Do to push blue button say DVR.

English: Push the blue button labeled "DVR."

I am not a mac expert, so I can't give you any details of parts. However, to take a composite video signal into the computer, you will need an analog video capture port. I believe that some macs have them but others will need an add on. USB devices are easy to buy and connect. Once you have the hardware, you need video capture software, quite possibly available as part of the mac OS but otherwise available to buy or download. The last thing you need is a big hard disk. Video eats hard disks and if you are planning to edit video, you should try to capture the video in an uncompressed format, which takes even more space that MPEG files.

Getting service from a cable company is generally cheaper. Most cable company's DVR service seem to run approx. $10 per month, in addition to your current cable company bill. Generally, there is no equipment to purchase so the only cost you pay is your monthly bill. Note: This may or may not be the case with your cable company. Consult your cable company for exact pricing and terms for DVR service. Purchasing your own DVR can mean anywhere from roughly $100 (for a standard TiVo DVR) to $600 for some higher-end DVRs. The higher-end DVRs include fancy features such as DVD recording and the like. Plus, you may pay an additional monthly fee, ($12 per month for TiVo, for example). While purchasing your DVR may be more expensive initially, your DVR offers more features and flexibility than your cable company's service. **alternate response** In my neck of the woods (South FL)renting a cable DVR is $8 monthly for the hardware rental and an additional $5 for programming service. I pay $5 a month for a DirecTV DVR programming with a hardware lump sum cost of $50 (the hardware is often available for free with a new installation)

Hi,

You should be able to do it with the right equipment. A lot depends on your DVD recorder and its capabilities and whether or not your cable box has the appropriate outputs on it.

Just remember, "Where there's a will, there's a way".

Hope this helps,

Tanks as we currently know them are obsolete; for the same reasons that battleships are. 1. Too heavy, non-air transportable. 2. They need infantrymen to protect them. 3. They are designed to engage other tanks; wars today require mobility (light weight), fast deployment (air transportable), and combined arms (infantry carrying tanks: landing in a hostile environment ready for battle); instead of waiting on the flight line for infantrymen and tanks to "get together"...they should already BE TOGETHER! Be combined! So, tanks are not obsolete; only the tanks of today. They need to "evolve" into tanks to fight 21st century battles.

Unscrew all those little screws.
