a) A device used to form a single composite color signal (NTSC, PAL, or SECAM) from a set of component signals. An encoder is used whenever a composite output is required from a source (or recording) which is in component format. b) Sometimes devices that change analog signals to digital (ADC). All NTSC cameras include an encoder. Because many of these cameras are inexpensive, their encoders omit many of the advanced techniques that can improve NTSC. CAV facilities can use a single, advanced encoder prior to creating a final NTSC signal. c) An embodiment of an encoding process.

A process that reads a stream of input pictures or audio samples and produces a valid coded bit stream as defined in the Digital Television Standard.
Industry:Entertainment
The process of coding data so that a specific code or key is required to restore the original data. In broadcast, this is used to make transmission secure from unauthorized reception as is often found on satellite or cable systems.

In 1988 a consortium of nine companies developed 32-bit EISA which was compatible with AT architecture. The basic design of EISA is the result of a compilation of the best designs of the whole computer industry rather than (in the case of the ISA bus) a single company. In addition to adding 16 new data lines to the AT bus, bus mastering, automated setup, interrupt sharing, and advanced transfer modes were adapted making EISA a powerful and useful expansion design. The 32-bit EISA can reach a peak transfer rate of 33 MHz, over 50% faster than the Micro Channel architecture. The EISA consortium is presently developing EISA-2, a 132 MHz standard.
