An encoder is a device, circuit, transducer, software program, algorithm or person that converts information from one format or code to another, for the purposes of standardization, speed, secrecy, security, or saving space by shrinking size.
[edit] Examples
Software for encoding audio, video, text into standardized formats:
- A compressor encodes data (e.g., audio/video/images) into a smaller form (See codec.)
- An audio encoder may be capable of capturing, compressing and converting audio
- A video encoder may be capable of capturing, compressing and converting audio/video
- An email encoder secures online email addresses from email harvesters
- A PHTML encoder preserves script code logic in a secure format that is transparent to visitors on a web site
- A multiplexer combines multiple inputs into one output.
[edit] Job positions
- A Data Entry Encoder may enter data from phone surveys in a coded format into a database.
- A Data Entry Encoder may enter payment amounts from legal tender documents from financial institutions into a database.
- A Manual Encoder may manually scan code tags on baggage that were missed by an automated system.
[edit] Security
- A device or person that encodes or encrypts military messages, such as the ADFGVX Cipher in WWI or the Enigma device in WWII.
- A Microchip hopping encoder integrated circuit for non-fixed-code secured entry.
[edit] Medical encoding software
- EncoderPro searches ICD-9-CM, CPT and HCPCS Level II medical codes, to increase accuracy and allow ease of auditing for compliance.
[edit] Transducers
Transducers for encoding position or orientation:
- A rotary encoder converts rotary position to an analog (e.g., analog quadrature) or digital (e.g., digital quadrature, 32-bit parallel, or USB) electronic signal.
- A linear encoder similarly converts linear position to an electronic signal.
[edit] Telecommunications
[edit] Encoder circuits
- A simple encoder assigns a binary code to an active input line.
- Priority encoders establish the priority of competing inputs (such as interrupt requests) by outputing a binary code representing the highest-priority active input.
