A packet consists of a header followed by a number of contiguous bytes from an elementary data stream. It is a layer in the system coding syntax.
Industry:Software
The matrix and its control that select the video sources feeding each of the four quadrants of a quad split. This is a separate option on the 4100 but has been integrated into the quad split on the AVC.
Industry:Software
A concept of aspect ratio accommodation central to the selection of the 16:9 aspect ratio for the SMPTE HDEP standard. In a shoot and protect system, in production the action is confined to certain bounds (the shoot range) but a larger area (the protect range) is kept free of microphone booms, lights, and other distracting elements. Shoot and protect has been used for years in film, where the shoot aspect ratio is the 1.85:1 used in NTSC. The 16:9 aspect ratio was selected mathematically as the one requiring the least area to protect both 1.33:1 television and 2.35:1 widescreen film. In such a system, both the shoot and the protect aspect ratios would be 16:9. A rectangle of shoot width and protect height would be 1.33:1 (12:9); a rectangle of shoot height and protect width would be 2.35:1 (about 21:9). The concept of 3-perf film conflicts strongly with 1..85:1 shoot and protect.
Industry:Software
The mechanism that extracts magnetic tape from a storage device, moves it across magnetic heads at a controlled speed, and then feeds it into another storage device. Typical storage devices are tape loops, bins, reels, and magazines (cassettes, cartridges). The tape transport is one part of a magnetic tape recorder/reproducer system that normally consists of: magnetic heads, magnetic tape, tape transport, record electronics, and reproduce electronics.
Industry:Software
When a system processor is reading or writing a memory or peripheral device that cannot respond fast enough, one or more time intervals (typically on the order of tens of nanoseconds each) are inserted during which the processor does nothing but wait for the slower device. While this has a detrimental effect on system throughput, it is unavoidable. The number of wait states can be reduced using techniques such as CPU-bus caches or write FIFOs.
Industry:Software
Light that emanates from a given point with equal intensity in all directions with a maximum intensity at its position. It exponentially dies out to zero at the distance of its radius. This is called the sphere light source.
Industry:Software
Increases the overall efficiency of a multichannel digital television transmission multiplex by varying the bit-rate of each of its channels to take only that share of the total multiplex bit-rate it needs at any one time. The share apportioned to each channel is predicted statistically with reference to its current and recent-past demands.
Industry:Software
To seek the cause of a malfunction or erroneous programme behaviour in order to remove the malfunction.
Industry:Software
Contiguous bytes of data from an elementary data stream present in the packet.
Industry:Software
The visual effect of dividing a picture into four segments, each of which may display video from a separate source. Also the name of the switcher panel module which controls this effect.
