A) The command interpreter between the user and the computer system. b) A window into which you type IRIX, UNIX, or DOS commands.
Industry:Software
The deviation of a tape from following a linear path when transported across the heads, causing a time displacement between signals recorded on different tracks and amplitude differences between the outputs from individual tracks owing to variations in azimuth alignment. The adjectives static and dynamic are used to distinguish between the steady and fluctuating components of tape skew.
Industry:Software
Memory devices whose stored data is lost when power is removed. RAMs can be made to appear nonvolatile by providing them with back-up power sources.
Industry:Software
This clock divides the incoming horizontal line of video into pixels. The pixel clock is very stable relative to the incoming video or the picture will not be stored correctly. The higher the frequency of the pixel clock, the more pixels that will appear across the screen.
Industry:Software
Video format developed to allow the storage and transmission of digital video. The 625/50 SIF format has a resolution of 352 x 288 active pixels and a refresh rate of 25 frames per second. The 525/59.94 SIF format has a resolution of 352 x 240 active pixels and a refresh rate of 29.97 frames per second. MPEG-1 allows resolutions up to 4095 x 4095 active pixels, however, there is a “constrained subset” of parameters defined as SIF. The computer industry, which uses square pixels, has defined SIF to be 320 x 240 active pixels, with a refresh rate of whatever the computer is capable of supporting.
Industry:Software
Trellis coding is a source coding technique that has resulted in numerous publications and some very effective source codes.
Unfortunately, the computational burden of these codes is tremendous and grows exponentially with the encoding rate. A trellis is a transition diagram, that takes time into account, for a finite state machine. Populating a trellis means specifying output symbols for each branch, specifying an initial state yields a set of allowable output sequences. A trellis coder is defined as follows: given a trellis populated with symbols from an output alphabet and an input sequence x of length n, a trellis coder outputs the sequence of bits corresponding to the output sequence x that maximises the SNR of the encoding.
Industry:Software
A compression method where a graphics accelerator transfers more than one bit on each clock cycle, then reassembles the fragmented pixels. For example, some chips can transfer 8, 24-bit pixels in three clocks instead of the four normally required, saving bandwidth.
Industry:Software
A cable with a conductive covering which reduces the possibility of interference with radio, television, and other devices.
Industry:Software
The speed at which tape is transported from feed (supply) to takeup reels during normal recording or reproduction.
