endec
An endec is a device which both encodes and decodes, either with the same or separate circuitry or
algorithm. The combining of these names is a portmanteau.
The general difference between an endec and a codec is that hardware is usually considered to be an endec, while software is considered to be the codec. Similarly, the word "encoding" is usually used for hardware, while "coding" is usually used in regard to software.
A program (or hardware) which uses a compression algorithm to create MPEG audio and/or video is often called an encoder, and one which plays back such files is a decoder. However, this is technically a codec, especially if performed in software.
Examples of encoders, decoders, and endecs:
- a modem is an endec, likewise a modulator is an encoder and a demodulator is a decoder
- an Emergency Alert System unit is usually an endec, but sometimes just a decoder
- a stereo generator used in broadcasting is an encoder
- A combination ADC and DAC would technically be an endec, though they are usually called CODECs
