DASH is an adaptive bitrate streaming technology where a multimedia file is partitioned into one or more segments and delivered to a client using HTTP. [15] A media presentation description (MPD) describes segment information (timing, URL, media characteristics like video resolution and bit rates), and can be organized in different ways such as SegmentList, SegmentTemplate, SegmentBase and ...
The DASH Industry Forum (DASH-IF) [1] is a system which according to the company "creates interoperability guidelines for the usage of the MPEG-DASH streaming standard. It consists of streaming and media companies, such as Microsoft, Netflix, Google, Ericsson, Samsung and Adobe." They provide an open source version of this software also.
It is now used to signal all kinds of program and ad events in linear transport streams and in newer ABR delivery formats such as HLS and DASH. Work on splicing GOP compressed video streams was started by SMPTE ST 312M Television - Splice Points for MPEG-2 Transport Streams. This standard had some basic signaling and details on how to perform ...
Although sometimes compared to DivX products, Xvid is neither a container format nor a video format, it is a software library that encodes video using specific coding profiles of the common MPEG-4 ASP video format. Those types of restrictions are intended to simplify the construction of multimedia recorders and players.
