Bit rate--The bit rate indicates the volume of the data stream per second. A higher bit rate results in higher quality. A distinction is made between constant bit rates (e. g. for -> VCD) and variable bit rates, e. g. Unlike constant bit rates, variable bit rates adjust the size of the data stream according to the video material. Blue screen--A variation of -> Chroma keying Capture--Recording. Chroma keying--Chroma keying uses a surface with a single color in front of which an actor, for example, is filmed. This color area is then made transparent during subsequent editing and can be replaced by a different background. Chrominance--Chrominance refers to the color signal in -> YUV, which is comprised of two color components: U, the balance between red and cyan, and V, the balance between yellow and blue. Composite video--Composite video is a transmission method common in the consumer sector that is generally realized using cinch connectors and which is frequently used, for example, on TVs. In this process, all signals (chrominance and luminance) share a single cable. The quality of composite video is lower than that of -> S video, in which chrominance and luminance are transferred separately. The part of your computer (processor, e. g. Pentium or Athlon), that does the actual computing. D8--Digital 8 is the successor to the Hi8 and VHS-C camcorder formats. Hi8 or D8 cassettes are still used, but the video data is recorded digitally in DV format. Data throughput--see Data transfer rate Data transfer rate--The data transfer rate describes the speed at which a hard drive can read or write data over a sustained period. The data transfer rate is usually measured in seconds, e. g. Device control--In DV terms, this refers to the ability to control your camcorder from your PC. DirectDraw--DirectDraw is a graphics standard initiated by Microsoft. Its features include the capability to write graphics data directly to the memory of the graphics board for the fluid display of video material. [. . . ] One second of video in the RGB color space would therefore require around 31. 6 MB of storage space. Using this process, a 2 GB hard drive would have a video capacity of around one minute. No current hard drive can deliver this volume of data in real time, but a number of options are available to reduce the data volume of the video signal substantially through transformation to a different color space (usually YUV) and compression (usually MJPEG). S video--Unlike -> Composite video, chrominance and luminance are transmitted separately in S video, resulting in higher quality. [. . . ]
