Live Edge

"Now" in a live video. The most recent frame of video the user could be seeing at a given time.

Time Shifting

VOD - Video on Demand

VOD (or Video on Demand) allows users to access videos without a traditional video playback device and the constraints of a typical static broadcasting schedule. Video can be controlled on demand, when the user chooses.

This is opposed to linear video, in which a video stream plays out a set schedule, and the user is only able to access the video being delivered at the current time.

Linear Video

Linear Video allows users to access videos on a schedule, without control over the playback.

This is opposed to VOD, in which the user has access and control over the content and devices, as well as when they are played back.
