Media Presentation Description (MPD) is a manifest file that contains information about content that is streamed using MPEG-DASH. MPD is an XML document that contains metadata that a DASH client uses to construct HTTP URLs and provide streaming services to users.
Low-latency HTTP Live Streaming (LL-HLS) is an extension of the HLS protocol designed to minimize latency in video streaming. While both LL-HLS and HLS are based on similar principles and share many features, the key difference lies in their focus on reducing latency.
Low-Latency Dynamic Adaptive Streaming over HTTP (LL-DASH) is an extension of the MPEG-DASH protocol designed to minimize latency in video streaming. While both LL-DASH and DASH are based on similar principles and share many features, the key difference lies in their focus on reducing latency.
Key Performance Indicators (KPI) are metrics that are used to measure the performance of a streaming service.
ISO base media file format (ISOBMFF) is a standard for storing and exchanging media data.
ID3 is a metadata format that can be used to carry additional information in CMAF and transport streams.
Hypertext Transfer Protocol (HTTP) is an application protocol used for exchanging information over the Internet.
High Efficiency Streaming Protocol (HESP) is an adaptive HTTP-based video streaming protocol with a particular focus on low end-to-end latency and fast channel-change.
Event Message (emsg) boxes are often used to carry proprietary metadata since no standardised methods include a latency timestamp.
Encoder Boundary Point (EBP) 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].
