Explain the difference between analog and digital video.?

Most of the information in this guide applies to all video cameras whether they are digital or analog. Analog is the term used for all older style video cameras, recorders and players. The main feature of analog representations is that they are continuous. Digital representations consist of values measured at discrete intervals. These intervals can be so short as to simulate continuous movement.\n~~~Logigly  video images comes from a tape or memory card~~~\n~~~if you wish to understand the difference between Analog and digital video you must first understand the diference between those who created them (CAMERS) the difference between a digital and a analog camera~~~\nForm more documentetion Just CLick the link below:

DSP is used to retrieve data from a signal, then shape that signal anyway you want. Since it is digital it is much more efficient than analog, instead of 3 active filters you need only the software.  Go here: \n\nhttp://www.bores.com/courses/intro/basics/1_whatis.htm

Different photoreceptors respond more or less strongly to different wavelengths (colours) of light. Digital cameras use more than one type of photodector for each pixel of the picture. By comparing the strengths of the signals from different detectors you can tell what colour the pixel should be.\n\nFilm cameras do the same thing, but use different chemicals in the film instead of photodectors. The different chemicals respond to different wavelengths of light.

Digital video is a type of video recording system that works by using a digital, rather than analog, representation of the video signal. This generic term is not to be confused with the name DV, which is a specific type of digital video. Digital video is most often recorded on tape, then distributed on optical discs, usually DVDs. There are exceptions, such as camcorders that record directly to DVDs, and Digital8 camcorders which encode digital video on conventional analog tapes.

digital video signal input. Most components nowadays that put out digital video signal uses HDMI. hope that helps

You will need a digital video camera or a method to convert to digital format from an analog video camera.  \n\nAfter shooting your video, you will need to capture the video to your computer.  You can edit your video with applications like:\n\nApple Final Cut Pro - http://www.apple.com/finalcutstudio/finalcutpro/\nAdobe Premiere - http://www.adobe.com/products/premiere/index.html\n\nOr you can use an online video-editing platform.\n\nJumpCut - http://www.jumpcut.com\n\nAfter editing your video, be sure to export your video with compressed codec such as QuickTime or MPEG.  With that file, you can upload your file to YouTube, Grouper and/or MetaCafe for coversion to Flash Video and share publicly.\n\nYouTube - http://www.youtube.com\nGrouper - http://www.grouper.com\nMetaCafe - http://www.metacafe.com\n\nGood Luck.

It depends on what you class as a television. There were monitors around before the camera such as wave form and vectorscope monitors so that engineers could see visual images of electronic activity within an electronic system such as radio. They used these when researching how to capture moving images i.e. the TV camera, we still use them for monitoring the technical quality of the pictures we produce. But in terms of what the general public knows as a TV monitor it was developed concurrently with the camera. The picture was captured on a tube converted into signal sent down a cable and then reproduced on the tube in the TV.\nI've just had this debate with one of our technical directors our news director and some other staff and the majority say the monitor or TV in it's crudest form came before the camera.\nHope this helps.

Its all about digital signals rather than analogue.  By 2012 you will have to be digital compatible otherwise you'll have a blank screen...;

When converting an analog recording to a digital format, you will always lose quality, no exceptions.  Likewise, you cannot recapture quality by putting a digital recording in an analog format.\n\nUnfortunately, analog is superior in quality but terribly clumsy.  If any old folks like me remember 8 track tapes...8 tracks sounded awesome, but were very cumbersome and very fragile.  \n\nIf there was some way to carry around 4-inch studio quality tape in an iPod-sized package, we would all be in high-fidelity heaven.

Most multimedia software will only work with digital video.  At least editing video is done digitally.  Even the big expensive video editing labs will transfer their beta/video to digital format, such as Sony EditStation or Final Cut Pro, and then export the digitized format back onto an analog tape.  For home multimedia production, you should get a hold of an analog/digital converter.  I found a nice here:\n\nhttp://dv411.com/advc110.html\n\nIf you need to edit your video, you can go high end and purchase a program like Adobe Premier.  Otherwise, I've found that you can easily do simple editing procedures in QuickTime pro, export your video to mpeg, avi, or mov formats, and retransfer to analog.  Hope this helps!

digital camera is the opposite of analogue camera.

Pretty sure yes. If anything, digital would be easier to spy on than analog.

I think you have that backwards.  Monitors have historically been analog (VGA), but more and more are now becoming available with digital inputs (DVI).\n\nDigital offers many benefits over analog, including longer cable lengths and a superior picture, but suffers (currently) from extra expense.  However the price gap is constantly decreasing, and before long analog monitors will become as much a historical curiosity as black-and-white TV.\n\nThe main reason for the improved clarity is that a digital interface allows your video card to directly address each and every pixel on your monitor individually.  No longer does the monitor have to approximate the desired result; the card can tell it precisely what needs to be displayed on every discrete pixel.\n\nIf you get a chance to try a dual-input monitor on a dual-output PC, you'll be amazed at just how much sharper the digital image is when you switch between the two sources.

Generally, the distinction between electronics and electrical is not actually one of voltage, but one of complexity and delicacy. "Electrical" generally refers to simple circuitry - for example things like power transmission and generation (these are done with relatively robust and crude circuits, though they are definitely not simple!). By contrast, electronics tends to refer to applications which are much more delicate - for example signal processing and similar.\n\nBut that said, the distinction is pretty fluid and you just tend to get a feel for what counts as "electronic" and what counts as "electric".

Because there was no option (apart from Morse code, Telegraphy, Teleprinter) until recently. \nFor transmission of domestic television and radio, digital is a relatively new alternative to analogue. And digital is not much use to the bulk of the viewers/listeners who have a house full of analogue equipment.
