Precision Time Protocol (PTP) is a time standard. It enables other technologies, ex. the 2110 protocol, to keep accurate timing between audio, video, closed captioning and other metadata.
Digital Rights Management (DRM) is the use of keys and certificates to authorize playback of a video stream to a specific user and/or device over IP streaming like OTT. DRM provides a mechanism to distribute content encryption keys securely, to specify rules for the use of those keys, and to
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
Streaming Video Technology Alliance is the International Technical Association which provides a forum for companies around the world in the streaming video industry to collaborate on improving streaming video interoperability.
Secure Reliable Transport is an open-source video streaming protocol and technology used to transmit high-quality video and audio streams over unreliable or unpredictable networks, such as the public Internet. SRT was developed by Haivision, and it has gained widespread adoption in the broadcast and streaming industries due to its focus
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.
Moving Picture Experts Group (MPEG) is a working group of experts that develops standards for audio and video compression and transmission.
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.
