ICY is an HTTP-based protocol and header (used by internet radio servers like Icecast and SHOUTcast) embedded within the audio stream. The ICY protocol allows audio players to request metadata which is then inserted into the stream at regular intervals. The client can extract and display this information which can
Precision Time Protocol (PTP) is a time standard. It enables other technologies, ex. the 2110 protocol, to keep accurate timing between audio, video, closed captioning and other metadata. It provides for higher precision than NTP (Network Time Protocol).
Secure Reliable Transport is an open-source video streaming protocol and technology used to transmit high-quality video and audio streams over unreliable or unpredictable networks, such as the public Internet. SRT was developed by Haivision, and it has gained widespread adoption in the broadcast and streaming industries due to its focus
Presentation Timestamp (PTS) is a crucial concept used to ensure the proper synchronization and presentation timing of media segments within an HLS stream. PTS helps maintain the correct order and timing of audio and video components during playback.
Moving Picture Experts Group (MPEG) is a working group of experts that develops standards for audio and video compression and transmission.
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
Hardware or software that encodes or decodes a data stream (e.g. audio, video, closed captions).
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.
File with .mov extension which uses QuickTime File Format (QTFF) multimedia container to store audio, video and metadata.
