Coordinated Video Timings (CVT; VESA-2013-3 v1.2 [1]) is a standard by VESA which defines the timings of the component video signal. Initially intended for use by computer monitors and video cards , the standard made its way into consumer televisions .
Although not an official name, this term is now used to refer to 1152×864, which is the largest 4:3 array yielding less than a binary megapixel (2^20, 1048576 pixels, 1048 decimal kilopixels), thus allowing the greatest "normal" resolution at common colour depths with a standard amount of video memory (128 kB, 512 kB, 1 MB, 2 MB, etc.).
Video compression schemes for Web and DVD make use of a 4:2:1 color sampling pattern, and the DV standard uses 4:1:1 sampling ratios. Professional video codecs designed to function at much higher bitrates and to record a greater amount of color information for post-production manipulation sample in 4:2:2 and 4:4:4 ratios.
Frame rate up-conversion (FRC) is the process of increasing the temporal resolution of a video sequence by synthesizing one or more intermediate frames between two consecutive frames. A low frame rate causes aliasing, yields abrupt motion artifacts, and degrades the video quality. Consequently, the temporal resolution is an important factor ...
When analog video is converted to digital video, a different sampling process occurs, this time at the pixel frequency, corresponding to a spatial sampling rate along scan lines. A common pixel sampling rate is: 13.5 MHz – CCIR 601, D1 video; Spatial sampling in the other direction is determined by the spacing of scan lines in the raster. The ...
In computer graphics, a video card's pixel fillrate refers to the number of pixels that can be rendered on the screen and written to video memory in one second. [1] Pixel fillrates are given in megapixels per second or in gigapixels per second (in the case of newer cards), and are obtained by multiplying the number of render output units (ROPs) by the clock frequency of the graphics processing ...
