Transmission , processing and playback by detroit

The video technology (Lat. video = I see, from videre to see) the electronic method for recording, transmission , processing and playback of moving images as well as possibly the accompanying sound ( see audio ), and digital photography as well as static images. This also includes the equipment used, such as video camera , video recorder and monitor . But the purely digital processing of optical signals is counted for video technology.

Analog video signals have been known since the thirties. At this time that the technology that later led to the development of television. Typical of analog video signals, the row-wise scanning (scan) of an interlaced image. At the end of each scanned line jumps back to the beginning of the next line, at the end of the whole (half) of the image to the beginning of the scanning device. This is called interlacing. Until the eighties, the sampling of an image for video purposes, typically through the line at a deflection of an electron beam over a photosensitive layer.

As a storage medium of sound and image was the first magnetic tape , usually in a video tape , in analog form, as in the Video Home System (VHS). Since 1996, digital recording is used increasingly so in the digital video (DV) system for camcorders.

Recently, magneto-optical techniques are increasingly combined with digital compression is used, in DVD camcorders . Since the late 1990s years while setting the digital MPEG -technology standards. On it is based include the video-CD , the DVD and the Digital Video Broadcasting (DVB). It stands out against DV further improved image quality, greater compatibility in the PC area, as well as lighter and more extensive editing capabilities. The MPEG-4 format offers advantages over MPEG-2 in turn implies greater compression, but requires greater processing power for recording and playback. Also it can with MPEG-4 rather lose quality through compression artifacts come.

The Phase Alternating Line system (PAL system) is used in the German-speaking television standard. Pal was developed in 1963 by Telefunken. It contains 625 scan lines (scan lines) per image (frame), 25 frames per second, corresponding to a duration of 40 ms / frame. The aspect ratio is 4:3, the pixels are square. PAL uses the YUV color model. The presentation is in interlace mode, each image is thus divided into two fields, one with the even and odd one with the grid lines. Because of the changing image space only 576 lines are visible. PAL can be found in eg Brazil, China, Germany and India.

NTSC is the 1953 by the NTSC (National Television Systems Committee) standard U.S. television set. NTSC contains 525 scan lines per image, play with exactly 29.97 frames per second, corresponding to 33.37 ms per frame. From time to time one reads 30 frames per second, but this is incorrect. The aspect ratio is 4:3, the pixels are square. The presentation is in interlace mode, each image is divided into two half frames (fields), divided one with the even and one odd, with the grid lines. At the beginning of each video field are 20 raster lines reserved, therefore, remain a maximum of 485 scan lines of picture information. Of these, only 480 but once again visible. Therefore, NTSC resolution of 640 x 480 pixels. PAL uses the YIQ color model. NTSC can be found eg in Japan, USA, Canada and Korea.

While everyone is getting in shape using their Wii or Microsoft Kinect, Bally Total Fitness, a popular gym chain, has hopped on board and leveraged SoftKinetic technology to install futuristic gesture-based interactive video walls on their gyms.

Basically, imagine an eight-foot tall television with a gesture camera (like Xbox Kinect) that gym-goers can manipulate without touching. The screens will have fitness and nutrition information, workout tips and even a feature that â€slims down†a photo of the user, to help get them get educated and excited about fitness.
