Α video codecis softwareor a device that provides encodingand decodingfor digital video, and which may or may not include the use of video compressionand/or decompression. Most codecs are typically implementations of video coding formats. The compression may employ lossy data compression, so that quality-measurement issues become important.
Adaptive bitrate streaming works by detecting a user's bandwidth and CPU capacity in real time, adjusting the quality of the media stream accordingly. [2] It requires the use of an encoder which encodes a single source media (video or audio) at multiple bit rates. The player client [3] switches between streaming the different encodings ...
A typical method of performing a measurement is to transfer a 'large' file from one system to another system and measure the time required to complete the transfer or copy of the file. The throughput is then calculated by dividing the file size by the time to get the throughput in megabits, kilobits, or bits per second.
HTTP Live Streaming (also known as HLS) is an HTTP -based adaptive bitrate streaming communications protocol developed by Apple Inc. and released in 2009. Support for the protocol is widespread in media players, web browsers, mobile devices, and streaming media servers. As of 2022, an annual video industry survey has consistently found it to be ...
Standard. ISO/IEC 23009-1:2022. Dynamic Adaptive Streaming over HTTP (DASH), also known as MPEG-DASH, is an adaptive bitrate streaming technique that enables high quality streaming of media content over the Internet delivered from conventional HTTP web servers. Similar to Apple's HTTP Live Streaming (HLS) solution, MPEG-DASH works by breaking ...
The Stream Control Transmission Protocol (SCTP) is a computer networking communications protocol in the transport layer of the Internet protocol suite.Originally intended for Signaling System 7 (SS7) message transport in telecommunication, the protocol provides the message-oriented feature of the User Datagram Protocol (UDP), while ensuring reliable, in-sequence transport of messages with ...

t. e. Streaming media refers to multimedia for playback using an offline or online media player that is delivered through a network. Media is transferred in a "stream" of packets from a server to a client and is rendered in real-time; [ 1 ] this contrasts with file downloading, a process in which the end-user obtains an entire media file before ...
