A General encoder's block diagram. An encoder (or "simple encoder") in digital electronics is a one-hot to binary converter. That is, if there are 2 n input lines, and at most only one of them will ever be high, the binary code of this 'hot' line is produced on the n-bit output lines. A binary encoder is the dual of a binary decoder.
The field of channel coding is concerned with sending a stream of data at the highest possible rate over a given communications channel, and then decoding the original data reliably at the receiver, using encoding and decoding algorithms that are feasible to implement in a given technology.
Audio encoder, converts digital audio to analog audio signals; Video encoder, converts digital video to analog video signals; Simple encoder, assigns a binary code to an active input line; Priority encoder, outputs a binary code representing the highest-priority active input; 8b/10b encoder, creates DC balance on a communication transmission line
A codec is a computer hardware or software component that encodes or decodes a data stream or signal. [1] [2] [3] Codec is a portmanteau of coder/decoder.[4]In electronic communications, an endec is a device that acts as both an encoder and a decoder on a signal or data stream, [5] and hence is a type of codec.
A bitstream format is the format of the data found in a stream of bits used in a digital communication or data storage application. [1] The term typically refers to the data format of the output of an encoder, or the data format of the input to a decoder when using data compression.
The physical layer is responsible for physical transmission of the data, link encapsulation allows local area networking, IP provides global addressing of individual computers, and TCP selects the process or application (i.e., the TCP or UDP port) that specifies the service such as a Web or TFTP server. [7]
In telecommunication technology, a Barker code or Barker sequence is a finite sequence of digital values with the ideal autocorrelation property. It is used as a synchronising pattern between the sender and receiver of a stream of bits.
Turbo codes are used in 3G/4G mobile communications (e.g., in UMTS and LTE) and in satellite communications as well as other applications where designers seek to achieve reliable information transfer over bandwidth- or latency-constrained communication links in the presence of data-corrupting noise.
