CA

A certificate authority or certification authority (CA) is an entity that issues digital certificates, which certifies the ownership of a public key by the named subject of the certificate.

CABAC

Abbreviation of Context-based Adaptive Binary Arithmetic Coding. More advanced and gives a better bit-rate-to-quality economy at the cost of higher processing power. For higher-quality applications such as large-format web video.

CAVLC

Abbreviation of Context-based Adaptive Variable Length Coding. A form of entropy coding used in AVC video encoding. An inherently lossless compression technique.

CBR

Abbreviation of Constant Bit Rate. The encoder/transcoder generates a constant number of bits over a period of time.

CDN

Abbreviation of Content Delivery Network. A large distributed system of servers deployed in multiple data centers in the Internet. The goal of a CDN is to serve content.

CIDR Notation

CIDR notation is a compact representation of an IP address and its associated routing prefix. The notation is constructed from an IP address, a slash ('/') character, and a decimal number. The number is the count of leading 1 bits in the subnet mask. Larger values here indicate smaller networks. The maximum size of the network is given by the number of addresses that are possible with the remaining, least-significant bits below the prefix.

CIFS

Abbreviation of Common Internet File System. Also known as Server Message Block, operates as an application-layer network protocol mainly used for providing shared access to files, printers, and serial ports and miscellaneous communications between nodes on a network.

CLI

Abbreviation of Command Line Interface. A means of interaction with a computer program where the user (or client) enter lines of text to issue commands to the program.

Closed Captioning

Abbreviated as CC. The act or process of including text as the transcription of the audio portion to a digital video stream or program. Closed Captions is the actual text that appears on the screen during closed captioning.

Cloud Encoder

An encoder that does not include any video capture cards. A cloud encoder requires the use of a source encoder streaming input.

Codec

enCOder/DECoder. A device or computer program capable of encoding and/or decoding a digital data stream or signal. A codec is a particular technology or method used to compress an electronic signal, such as a video or audio recording.

Color Space

Defines colors as a function of the absolute reference frame, color spaces, along with device profiling, to allow reproducible representations of color, in both analogue and digital representations.

Command Line Interface

Abbreviated as CLI. A means of interaction with a computer program where the user (or client) enter lines of text to issue commands to the program.

Common Internet File System

Abbreviated as CIFS. Also known as Server Message Block, operates as an application-layer network protocol mainly used for providing shared access to files, printers, and serial ports and miscellaneous communications between nodes on a network.

Composite Video

An analog video transmission (without audio) that carries standard definition video typically at 480i or 576i resolution.

Connection Speed

The performance of an Internet connection based on the number of bytes per second that data travels from the user's device to the Internet (upload) or from the Internet to the user's device (download).

Constant Bit Rate

Abbreviated as CBR. The encoder/transcoder generates a constant number of bits over a period of time.

Content Delivery Network

Abbreviated as CDN. A large distributed system of servers deployed in multiple data centers in the Internet. The goal of a CDN is to serve content.

Context-based Adaptive Binary Arithmetic Coding

Context-based Adaptive Variable Length Coding

Abbreviated as CAVLC. A form of entropy coding used in AVC video encoding. An inherently lossless compression technique.

Cooperative Research and Development Agreement

Abbreviated as CRADA. A written agreement between a private company and a government agency to work together on a project.

CRADA

Abbreviation of Cooperative Research and Development Agreement. A written agreement between a private company and a government agency to work together on a project.

cURL

Command line tool for getting and sending files using the URL syntax.
