Vertical Interval Timecode (VITC) is a method of encoding timecode information into the VBI of a video signal, typically an analog video signal like NTSC or PAL. VITC timecode is used to precisely identify and label each frame of video in a sequence.
Vertical Blanking Interval (VBI) is a period of time within the vertical blanking period of a video signal. It is a fundamental component of analog television and some legacy video formats. The VBI occurs between the end of one video field (or frame) and the start of the next field
Supplemental Enhancement Information (SEI) is data that can be embedded within H.264 or H.265 video streams and can be used for various purposes, such as signaling information to the decoder or conveying metadata related to the video.
Presentation Timestamp (PTS) is a crucial concept used to ensure the proper synchronization and presentation timing of media segments within an HLS stream. PTS helps maintain the correct order and timing of audio and video components during playback.
Producer Reference Time (PRFT) is a concept introduced in the context of LL-DASH. The PRFT supplies times corresponding to the production of associated media. Among other benefits, this information (i) provides media clients with information to enable consumption and production to proceed at equivalent rates, avoiding possible buffer overflow or
Microsoft Smooth Streaming (MSS) is a technology developed by Microsoft for adaptive bitrate streaming of media content over HTTP.
Moving Picture Experts Group (MPEG) is a working group of experts that develops standards for audio and video compression and transmission.
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.
