Digital Video Recorders

The first video cameras were produced in the 1920s in support of the early television systems. John Logie Baird built a camera as part of his television system demonstrated in 1925. Philo Farnsworth made a fully electronic camera that was demonstrated in 1929. The video camera, or television camera, is a fundamental part of television so cameras have been around for as long as television has existed.

Color cameras were developed and trialled in the 1950s and were used commercially in 1954 by RCA when they began successful broadcasting of color television in the US.

The next ambition among developers was to produce a portable, combined camera and recorder. The size of cameras and recorders in the 1950s made it impossible to call any device portable. It took the development of video cassettes to enable a truly portable "camcorder"

They were first developed for television production, especially for news telecasts of on-the-spot events; but they were soon marketed as a family resource-the record keeper of milestones such as weddings and graduations and a baby's first steps. Now video recording has come full circle as amateurs make spur-of-the-moment videos of events ranging from slices of life of their family and friends to major disasters or scandals.

Developments in camera and recording technologies has made the video camera and the camcorder more accessible over four decades. Both size and cost have reduced steadily to the point where they can be included in cell phones and deliver a quality that is similar or better than the first domestic camcorders of the 1970s and early1980s.

The purpose of a Direct TV HD DVR is for recording device for recording television shows and movies in HD from satellite television channels. Direct TV offers satellite television service in HD,

The manufacturer of your camcorder should have parts listed on their website for sale. If they do not, eBay is a great place to find those hard to find parts for anything.

I called yesterday to find out myself and I was told $16.95 per month.

First off: why would you bother? The video will be inferior, and tapes are getting harder to find because the VCR is a dying technology. If your answer is "My granny has a VCR", consider buying her a DVD player - you can buy one new for $30 or less at WalMart, and get one used at a yard sale for about $10 or so.

With that said, hook up the audio and video out jacks on the DVR (coded red, green and yellow) to the similar a/v in jacks on the VCR, set the VCR to record from these jacks (as opposed to recording from the tuner), press "record" on the VCR, and press "play" on the DVR.

No, once a DVD-R is burned (or even partly burned) there is no way to 'unburn' it for reuse.

All you need to do is run a coaxial cable from your set-top-box or TV antennea to the back of your VCR's "RF" or "ANT" in jacks. When you find something that you want to record, simply tune to that channel and press the record button on your VCR unit or remote control.

An AV output is one or several connectors that output both video and audio signals from a device. They are found on terrestrial and satellite receivers, video recorders as well as some televisions.

The output may be analog, using composite video, s-video, component or RGB with audio normally carried on a pair of connectors for left and right signals. Typically, domestic equipment will use RCA (phono) connectors although there are other connectors that are used in commercial equipment.

Digital outputs are normally restricted to HDMI on modern equipment - a single connector that carries video and audio signals. DVI may also be called an AV connector but as it does not carry audio, it doesn't strictly fit the definition. Broadcast equipment uses a single co-axial connection on a BNC connector and carries SDI, a digital signal that can carry video, audio and other signals.

Whatever the interface, it needs to be connected to a similar input to a television, a recorder input or similar device to link the output to any other equipment.

It depends...

If the DVR was purchased at a store and has a card slot....the answer may be yes.

TiVo stand alone systems, Panasonic, ARCHOS... etc

If your system was bought from Dish network.... Probably not.

DISH NETWORK AND DIRECTV are working on that option for their DVRs. DISH NETWORK's option allows the use of a standard external USB drive, but it formats in a propietary format so it cannot be moved from one DVR to another. Thank you RIAA and MPAA for that wonderful option!

DISH NETWORK currently has a series of DISHPlayers that video can be downloaded through the USB port on the DVR to the DISHPlayer personal video player

Alot of DVR's are through cable company's and most of them do require an additional montly fee . I do not know of any at this time that you can buy that do not require an additional fee for using .

tivo is a service you pay for its a dvr but its just called tivo and a dvr is a digital video recorder theres more than just tivo available. theres dvr boxes where you dont have to pay anything. hope it helps you

It's hard to say without knowing the type of video you are talking about. If it is full quality, component, digital standard definition video, then around one second. Use the same space for HD and it drops to 0.2 seconds. Compressed video is rather different and the figure can be anywhere between a few seconds to a few minutes, depending on the amount of compresison, the image size and the frame rate. Most video clips have a fixed data rate. Good quality compressed video will be in the region of 2Mb. 2Mb data will take up 0.2MBytes for each second or 5 seconds per megabyte. If you are trying to store video data for editing, then it is best to avoid compressing the data, so expect a shorter time for raw video.

There's usually a cord that comes with the camera that has a connection to the camera at one end and a usb or firewire port on the other. If the camera did not come with one, you could take your camera to best buy, Radioshack, basically any electronics place and they would be able to help you with a cord to connect your camera and computer.

Yes, although you may need to get a switch to select which recorder you want to watch.

The easiest solution is if your DVRs both have HDMI outputs, and the TV has 2 or more HDMI inputs. You simply select the DVR you want to watch by choosing the appropriate HDMI input. Similarly, if one DVR has an HDMI output and the other has component or composite outputs, you can also switch units by choosing the appropriate input on your TV.

If your TV does not have enough HDMI inputs (or none) then you may need to get a switching box that will allow you to connect two devices with composite or component outputs to a TV with only one set of inputs.

Yes, most analogue camera's have an AV output. It may have a special small plug and an adapter ending in 3 phono plugs. Red=Right audio, White=Left audio, and Yellow= composite video.

Most Digital TV's have AV inputs, which you can select from the menu.

Connect the cable to the TV, select the correct AV in, play the camera. It should now show on the screen.

For every program being received, a tuner is required. A dual tuner allows one channel to be viewed and one other to be recorded. It is normally possible to record the channel that is being viewed, so strictly, yes, it is possible to record two shows while watching one of them. Watching a third channel is not possible.

If you're talking about optical zoom there is no difference other than you will be closer to the viewed object.
If you are talking about digital zoom, the size of the pixels will increase and blur.
Hope that helps!

Send your tapes to a video transfer service. They will have a Hi8 player and be able to convert your tapes to DVD. Some, even have the option for you to edit online or get digital files back on a portable hard drive. StashSpace.Com can do this for $7 a tape. http://www.stashspace.com/video-transfer/hi8-dvd-transfer.stm

Another option is to borrow or purchase a Hi8 player from a friend. However, in this case you still need a video capture device to convert the analog signal to digital.

If you want to convert a Hi8 or standard 8 tape to DVD, you MUST have a player.

* If you only have one or two tapes, then try to borrow a friends, or purchase a Hi8 camera. * There are plenty of folk willing to do the conversion for you ... for a price. Anywhere from $5 to $10 per tape. * If you have lots and lots of tape, consider purchasing a tape player, not a camera.

I have a lot of Hi8 tape I need to covert, so I'm looking at purchasing a player.

While you're at it, you might want the files converted to MPEG4 or DIVX, as this allows for high quality at a small file size. I plan to convert all files to both MPEG4 (for future editing) and MPEG2 (which is used to create standard DVDs).

VCRs do NOT process digital signals, analgue is the only language they understand. Therefore, you need to place before the VCR a device that has a digital tuner plus the ability to convert digital signal to analogue.

Examples of such devices are a cable / satellite set-top box, a digital to analog converter box (the converter box ONLY works IF your digital TV feed is coming from an over-the-air TV antenna, not through underground cable), and a stand-alone DVD disk recorder "with a built-in digital tuner".

Whichever tuner plus converter device you have, connect either S-Video or Composite Video AND RCA (red and white) audio output of the device to the input sockets of your VCR. Make sure that whatever "types" of video and audio connections you make are available on both ends, as output on your tuner/converter device and input on your VCR.

It depends on the type. The most basic DVR recorders allow a user to record a program from TV onto a disc to be viewed later. Some DVRs offer other features including the ability to skip over commercials.

After extensive research on this, I'd have to say at least 30-60 days, but especially with the latest DVR systems, some companies may keep up to 2 years of footage easily.

No it does not. Technically, it never is 'off'. The two lines that come into the back of the DVR are both solid constant feeds coming in, and the DVR is constantly monitoring start times that are your scheduler.

** Additionally, it is BEST to 'shut off' the DVR when you want to record 2 simultaneous programs on different channels, so that it is not using one of the feeds to display the channel it is tuned to (even tho your tv is shut off) while the other feed is used for recording.

When the receiver is 'shut off' it will use both feeds to ensure successful recording of both programs.

Most DVRs have their own tuner(s) built in. So it is not a matter of recording from a TV.

A DVR can record alone without a TV being attached. The problem arises when you want to program it. You need the TV to act like a monitor and see what you are doing.
