HTTP Live Streaming uses a conventional web server, that implements support for HTTP Live Streaming (HLS), to distribute audiovisual content and requires specific software, such as OBS to fit the content into a proper format for transmission in real time over a network. The service architecture comprises:
Adaptive streaming overview Adaptive streaming in action. Adaptive bitrate streaming is a technique used in streaming multimedia over computer networks.. While in the past most video or audio streaming technologies utilized streaming protocols such as RTP with RTSP, today's adaptive streaming technologies are based almost exclusively on HTTP, [1] and are designed to work efficiently over large ...
When referring to codecs, constant bit rate encoding means that the rate at which a codec's output data should be consumed is constant. CBR is useful for streaming multimedia content on limited capacity channels since it is the maximum bit rate that matters, not the average, so CBR would be used to take advantage of all of the capacity. [1]
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. [18] 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 ...
There are two operational modes of VBV: Constant Bit Rate (CBR) and Variable Bit Rate (VBR). In CBR, the decoder's buffer is filled over time at a constant data rate. In VBR, the buffer is filled at a non-constant rate. In both cases, data is removed from the buffer in varying chunks, depending on the actual size of the coded frames.
Reliable Internet Stream Transport (RIST) is an open-source, open-specification transport protocol designed for reliable transmission of video over lossy networks (including the Internet) with low latency and high quality. It is currently under development in the Video Services Forum's "RIST Activity Group." [1]
Network Device Interface (NDI) is a software specification developed by the technology company NewTek.It enables high-definition video to be transmitted, received, and communicated over a computer network with low latency and high quality.
OBS Studio is a free and open-source app for screencasting and live streaming.Written in C/C++ and built with Qt, OBS Studio provides real-time capture, scene composition, recording, encoding, and broadcasting via Real-Time Messaging Protocol (RTMP), HLS, SRT, RIST or WebRTC.
