ARINC 818: Avionics Digital Video Bus (ADVB) is a video interface and protocol standard developed for high bandwidth, low-latency, uncompressed digital video transmission in avionics systems. The standard, which was released in January 2007, has been advanced by ARINC and the aerospace community to meet the stringent needs of high performance ...
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.
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
Video bandwidth requirements are growing continuously, as video resolutions, frame rates, bit depths, and the amount of video streams are constantly increasing. Likewise, the capacities of video links and communication channels are also growing, yet at a slower pace than what is needed to address the huge video bandwidth growth.
Traffic classes shall not exceed their preconfigured maximum bandwidth (75% for audio and video applications). The maximum number of hops is 7. The worst-case latency requirement is defined as 2 ms for Class A and 50 ms for Class B, but has been shown to be unreliable.
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]
Audio Video Bridging (AVB) is a common name for a set of technical standards that provide improved synchronization, low latency, and reliability for switched Ethernet networks. [3] AVB embodies the following technologies and standards: IEEE 802.1AS-2011: Timing and Synchronization for Time-Sensitive Applications (gPTP);
Apple also added new tools: tsrecompressor produces and encodes a continuous low latency stream of audio and video. The mediastreamsegmenter tool is now available in a low-latency version. It is an HLS segmenter that takes in a UDP/MPEG-TS stream from tsrecompressor and generates a media playlist, including the new tags above.
