Sample text

The SI prefix M denotes 106 (1 000 000). Disk storage is generally allocated in units integrally related to 1024 bytes; the prefix M applied to disk storage denotes 1 024 000. RAM memory generally has capacity based on powers of two; the prefix M applied to RAM denotes 220 or 1024 K (1 048 576). Data rate of digital video Line rate is an important parameter of a video system: Line rate is simply the frame rate multiplied by the number of lines per total frame. The aggregate data rate is the number of bits per pixel, times the number of pixels per line, times the number of lines per frame, times the frame rate.

This characteristic needs to be considered if an image is to be coded so as to minimize the visibility of noise and make effective perceptual use of a limited number of bits per pixel. Combining these two concepts – one from physics, the other from perception – reveals an amazing coincidence: The nonlinearity of a CRT is remarkably similar to the inverse of the lightness sensitivity of human vision. Coding intensity into a gamma-corrected signal makes maximum perceptual use of the channel. If gamma correction were not already necessary for physical reasons at the CRT, we would have to invent it for perceptual reasons.

Limiting resolution is defined as the frequency where detail is recorded with just 10 percent of the system’s lowfrequency response. In consumer television, the number of scanning lines is fixed by the raster standard, but the electronics of transmission, recording, and display systems tend to limit bandwidth and reduce horizontal resolution. Consequently, in consumer electronics the term resolution generally refers to horizontal resolution. Confusingly, horizontal resolution is expressed in units of lines per picture height, so once the number of resolvable lines is measured, it must be corrected for the aspect ratio of the picture.
