VOD or Interactive Video On Demand:
One of the coolest features of HLS streaming is its support for DVR controls. DVR controls allow consumers of video and music to jump forward and backward instantly, to a specific point in the video. DVR controls also permit fast and slow-motion play. DVR is now considered a must in the world of VOD.
Here are some features associated with DVR:
Interactive video on demand (IVOD) is the standard version of video on demand where people have the following features at their disposal:
Play/Resume - Start a program/movie from the beginning or resume after temporarily stopping the show.
Stop - Temporarily or permanently stop the presentation of the show.
Pause - Freeze the picture.
Jump forward - Jump to a particular time in the presentation (movie) in a forward direction.
Jump backward - Jump to a particular time in the presentation (movie) in a backward direction.
Fast Forward (FF) - Browse through the movie in the forward direction with picture and sound on.
Slow Down - Going forward at a lower rate than normal but with picture and sound.
Reverse - Playing the movie in the reversed direction with picture and sound.
Fast Reverse - Browse the presentation in the backward direction with picture and sound at a faster speed than standard reverse.
Slow Reverse: Go backward at a slower speed, with picture and sound.
Other interactive features include the ability to avoid or select advertisements, to investigate additional details about news events and to browse, select, and purchase goods.
Exclusive video on demand (EVOD) is when a particular TV-based VOD content provider offers a function, service and/or program that no other content provider has, it might be called exclusive video on demand.
Impulse video on demand (IVOD) is now typically referred to as "video on demand" but in the past, this term often referred to the ability to order TV-based video on demand programming, without having to first phone in your order to the network operator.
Quasi video on demand (QVOD) is the same as near video on demand except that the programming only will be presented if a minimum number of subscribers sign up for it.
Transactional video on demand (TVOD) is the opposite of subscription video on demand (SVOD). With transactional VOD the customer pays for each individual video on demand program. Secure TVOD authenticates to the video server to verify payment and authorize based on IP address. With its opposite, SVOD, typically the subscriber pays a set amount, (often monthly) for a set amount of video on demand. Now most refer to transactional VOD simply as "VOD".
Free video on demand (FVOD) is video on demand programming that a network operator makes available as part of a content package. FVOD can make it possible for subscribers to have unlimited access to movies/programming offered during a specific time period. The opposite would be subscriber video on demand (SVOD) where a subscriber pays a standard fee for programming that may have no, or limited advertisements. OnDemand is a UK-based company owned by the On Demand Group which offers FVOD through Inview Technology; their product Inview Inside is Royalty Free.
