Encoder
Examples
Media
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.
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.
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.
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.
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.
Telecommunications
A device used to change a signal (such as a bitstream) or data into a code.
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.
