Video of the term too much, I can not understand, who can provide information

Users questions: Now camera or display device, described in a variety of parameters, there are analog, there are figures, what is the relationship between them, other cameras and monitors, all the parameters described in a variety of manufacturers, I how to find some books or documents or sites, to understand the knowledge
Experts answer:1 . What V8? A: SONY company advertising may be too big, while many people have cameras all referred to as the V8, a large television camera called the largest professional V8, home video called V8, handheld called the Little V8. In fact, strictly speaking is not the kind referred to, the so-called because of his V8 Use of video bandwidth due to 8mm, but also record video with sound, full name Video8 called V8. Horizontal resolution of 270. 2. What Hi8? A: Hi8 and 8mm V8 use the same bandwidth for the video, but the level of resolution for the 400. 3. What is D 8? A: D8 for the SONY's next-generation models, with Hi8V8 the same bandwidth for the use of 8mm tapes, but a digital signal to record video, video time with a long half the original, full name Digital8 called D8. Horizontal resolution of 500. 4. What is VH S * VHS-C? A: The so-called VHS shall be known as the "big band", using 12mm bandwidth video. VHS-C to VHS in the narrow band, film only 30 minutes and 40 at the two, but EP recording up to 90 minutes slow and 120 points, you can use the converter box to make VHS-C change Into the standard big band VHS, VHS VCR to play the general. Because it is 12mm bandwidth video, it was also known as V12. 5. What is S-VHS * S-VHS-C? A: S-VHS * S-VHS-C and VHS * VHS-C to use the 12mm with the same Width of the video, but the level of resolution for the 400. 6. What is DV? A: DV for the next generation of digital video standard, smaller and longer. Using 6.35mm bandwidth video signals to digital video recording, video recording time is 60 minutes, LP mode with extended shooting Time to 1.5 times with a long, full name DigitalVideo referred to as DV. DV tapes currently on the market, there are two specifications, one is a standard DV tape, the other is reducing the miniDV tape, usually used in home video cameras are of such a reduced mi niDV band. Also with the video bandwidth for the 6.35mm, but also professional grade DVCAM and DVCPRO, They are specialized in SONY Corporation and Panasonic digital video camera special specifications. 7. What pixel CCD camera? A: The so-called C CD simply means that the camera window to the soul and the CCD itself looks like a long with a ICchip, chip above, there are many sensitive micro-components, sensitive components directly affects the amount of camera quality is good or bad, but its the photosensitive components are called "pixels." Generally V8V HS-C of the pixel is about 270,000, Hi8S-VHS-C of the pixel is 41 million, and DV models are from 41 to 680 000. 8. What OpticalZoom and DigitalZoom (Optical Zoom and Digital Zoom)? A: I remember early photography Machine stretch magnification is 6 times the maximum, but also, today is a big multiple of the amazing flexibility, two or three times the machines everywhere, but hidden mystery which is "optical" and "digital" in the. The so-called optical multiple is a multiple of the real camera, because it is relying on a multiple of the optical lens shift production Action to achieve, so optical Zoom is the most beautiful picture quality, the current largest optical multiple cameras about 20 times, but most models are between 10 to 18 times. The Zoom is a digital photograph of the film by the partial amplification of the results, imagine if a 3x5 photo to enlarge to 50 times, then the Board Department of the picture quality will become coarse, and put the greater the more rough. Zoom digital cameras the same multiple of the larger that the poorer quality. Many people buy the camera, often a multiple of the size of the camera to include one of the important considerations, in fact, is not a multiple of the most important, one has optical The camera has about 10 times and a 400mm telephoto lens camera multiple considerable, so do not blindly pursue multiple of the actual. For the author, the only digital multiple vendors gimmick Bale. 9. What is shock (SteadyShot)? A: "Earthquake!" ! Not
