Frequently used terms

Codecs: A software program that converts a video/audio signal into a compressed format to send over the internet. A codec is also required at
the receiving end to decompress the signal prior to viewing on a computer or mobile device. Most browsers and players come with the proper codecs installed.

Player: The software a computer or mobile device uses to play the video/audio stream. The player can be part of a browser, built into a website, or a stand-alone program (like Windows Media Player).

Encoding: A term used to describe what a codec does. For example, “The laptop encodes the signal from the camera before uploading to the Internet.”

CDN: A Content Delivery Network. CDNs are large computer networks, usually with locations all over the world, designed to handle large amounts of content (audio, video, image, etc.) in order to ensure high performance and low latency. Using a CDN helps ensure viewers have few, if any, delays in watching video even when watching high definition content.

Bandwidth: This refers to the amount of data transferred over a network (the Internet for example) in a given time. It is measured in bits per second (bits/s or bps), or more commonly Megabytes per second (Mbps) or Gigabytes per second (Gbps).
