Encoder Boundary Point is used by the ABR transcoder to signal segment boundaries that are used by the packager downstream to generate the segment files. Standardized by CableLabs [OC-SP-EBP-I01-130118].
Factors impacting client-side latency in ABR-based streaming.
HTTP Live Streaming is an Apple standard for ABR media streaming using fMP4 or MPEG-TS containers and H.264 or H.265 video codecs.
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
Dynamic Adaptive Streaming over HTTP is an MPEG international standard to enable non-proprietary ABR media streaming using fMP4 containers and any codec format.
Common Media Application Format 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.
Program content that has been encoded into a particular bit rate, frame size and/or frame rate. ABR streaming technology provides consistent, high-quality viewing in situations where bandwidth may fluctuate, and where viewers may be on a wide range of devices by combining multiple variants into a single package that represents
This paper explores the technology behind Multicast ABR and its potential to improve how video content is streamed over IP, meeting the network operator’s needs for a scalable way to deliver growing video traffic and end-users’ demands for the best possible streaming experience.
Unicast delivery in IP networks involves a 1:1 data transmission scheme where one host or endpoint is communicating with one other host or endpoint exclusively. Contrast with broadcast or multicast transmission models. Unicast has been heavily used in video with the arrival of ABR streaming, leveraging the HTTP protocol.
A manifest refers to a text file that describes other files that can be fetched as part of Adaptive Bitrate Streaming (ABR). A master manifest is a text file which describes a list of rendition manifests along with the resolution, bitrate, location (URL) and other details of each rendition. A rendition
