Capturing+Video


 * Video capture is the process of converting an analog video signal such as that produced by a video camera or dvd player to a digital form. The resulting data is refered to as a video stream. The video capture process involves several steps. **
 * ** 1st, the analog video signal is digitized by an analog to digital converter to produce a raw, digital data stream. In the case of composite video, the luminance and chrominance are seperated; this is not necessary for S-Video formats. **
 * ** 2nd the chrominance is demodulated to produce color difference video data. At this point, the data may be modified so as to adjust brightness, contrast, saturation and hue. **
 * ** 3rd the data is transformed by a color space converter to generate data in conformance with any of several color space standards, such as RGB ( a color model in which Red, Green and Blue are added to produce a broad array of colors and YCbCr(a family of color spaces used as a part of the color editing for video and photography imagery) Together, these stepts constitute video decoding, because they decode an analog video format such as NTSC or PAL. **


 * Special electronic circuitry is required to capture video from analog video sources. At the system level this function is typically performed by a video capture card. Such cards use video decoder integrated circuits to implement the video decoding process. **
