Encoded Bitrate is the bitrate of the compressed (i.e. during ABR encode/transcode) audio or video media objects, each Bitrate level representing different quality levels in ABR. The concept of Encoded Bitrate is inherent in various ABR-related definitions: e.g. CMCD br key, e.g. HLS Playlist Variant Stream BANDWIDTH parameter, e.g. DASH
Dynamic Adaptive Streaming over HTTP is an MPEG international standard to enable non-proprietary ABR media streaming using fMP4 containers and any codec format.
Hardware or software that encodes or decodes a data stream (e.g. audio, video, closed captions).
Common Media Server Data (CMSD) is a CTA standard (CTA-5006) published in 2022 defining how Origins and CDNs send status information to downstream workflow nodes (e.g. CDNs, players) with every object response.
Common Media Client Data (CMCD) is a CTA standard (CTA-5004) published in 2020 defining how player clients send playout and error status information to upstream workflow nodes (e.g. CDNs) with every object request.
Common Media Application Format (CMAF) is an Apple-Microsoft standard aiming to simplify workflows by defining concurrent use of multiple ABR methods (e.g. DASH, HLS) while using one set of audio and video media files.
Video compression standard, published in 2004, with the goal to succeed MPEG-2/H.262 by reducing bitrate up to 50% while maintaining the same perceptual video quality (PVQ).
File with .mov extension which uses QuickTime File Format (QTFF) multimedia container to store audio, video and metadata.
