	Video on demand - Wikipedia, the free encyclopedia
		VOD systems either "stream" content, allowing viewing while the video is being downloaded, or "download" it in which the program is brought in its entirely to a set-top box before viewing starts.
		All download and some streaming video on demand systems provide the user with a large subset of VCR functionality including pause, fast forward, fast rewind, slow forward, slow rewind, jump to previous/future frame etc. For streaming systems this requires more effort on the part of the server, and may also require greater network bandwidth.
		Near video on demand (NVOD) is a pay-per-view consumer video technique used by multi-channel broadcasters using high-bandwidth distribution mechanisms such as satellite and cable television.

		The problem with video on demand is that users can start streaming a movie at an arbitrary moment, so if there are 100 users all starting to watch some new movie at about 8 P.M., chances are that no two will start at exactly the same instant so they cannot share a stream.
		In a sense, video on demand is like using a taxi: you call it and it comes.
		Near video on demand is like using a bus: it has a fixed schedule and you have to wait for the next one.

		For our purposes, we assume that advanced video services provide, at the least, some minimal level of interactivity, since this is the underlying theme of almost all advanced video services from games to video on demand.
		NVOD would make these movies available every 15 minutes or so; however, typical VCR functionalities such as pause, rewind, and fast forward would not be available.
		NVOD, or at least "near" NVOD, is already available in the form of DBS to roughly half of all households.

		Near video on demand capability, while desirable to customers, does not provide customers all the instant control features of true video on demand.
		In a true video on demand system, movies are typically striped across multiple disks for the purpose of load balancing.
		For near video on demand, however, the input/output (I/O) workload for a movie is determined solely by the broadcast interval, not by viewer demand (instances of request).

	Scheduling Video Programs in Near Video-on-Demand Systems
		In NVoD systems, on the other hand, limited continuity in VCR actions can be provided by caching a small amount of video data (e.g., 5 minutes' worth of video) in a buffer located close to the client, for instance, in the customers' premise equipment (CPE).
		Support for continuous interactive functions in NVoD is provided by caching a limited amount of video data close to the user, for instance, in a CPE buffer, so that the user may access it with a very low latency during interaction [2].
		Video frames are received in a synchronous fashion, and those frames already displayed (``past frames'') are kept within the buffer, for reverse search and rewind capability.

		Video on Demand (VoD) enables subscribers to choose from a library of recorded films and TV programming, and watch them immediately on their TV set, usually via a set-top box.
		Providing a limited set of video streams which are defined and scheduled in advance is quite different from allowing users to select any one of a large number of videos at a time of their own choosing.
		And while nVoD can be offered by digital satellite or cable, true VoD is only possible over a service which can provide the end-user with their own dedicated broadband channel, all the way from the video server to the set-top box.

		Video on Demand has become one of Interactive Television’s major subcategory.
		Streaming video (sometimes known as HTTP Streaming video or Progressive Download) is when a file of the video is compressed and sent over a network, which can include the Internet.

		And once she has people looking at her videos, she can build advertising right into those as well -- either by displaying it in frames that accompany the media content, or by interspersing media segments with short advertising segments as they do in traditional radio or TV (see my discussion of the "play list model").
		The classic example is a sort of video club where you have things like "movies of the week", or new things coming on line on a regular basis.
		Another favorite example of mine is the video training company (like www.vtc.com) which has hundreds of training videos on line, with new ones coming on stream regularly, where a subscription gives you access to all of them.

		As cable television system operators continue to upgrade their networks to support 2-way digital transmission, they are well-positioned to offer interactive services such as Video on Demand (VoD), interactive TV, and other rich content services.
		At the distribution hubs the MPEG-2 video streams are extracted from IP packets and passed to a QAM device that transmits the VoD to the subscriber's Set Top Box (STB) over a VoD channel.
		This solution provides guaranteed bandwidth per service type (video, voice, or data) and ensures that admission to the network will be granted only to service flows whose QoS requirements can be satisfied by the IP network.

		Because HFC can carry both video and traditional telephony services, can provide line powering, and is compatible with both analog and digital services, installed facilities can deliver existing services while offering a transitional platform for the first broadband services.
		For video-on-demand (VOD) and near video-on-demand (NVOD), the cost per digital channel and modulator (HFC only) are shown as cost per basic video subscriber assuming a 20 percent subscription rate and a 20 percent peak usage rate.
		Meanwhile, initial capital outlays for HFC are generating revenue from telephony and near video-on-demand services now rather than sitting tied up in a non-productive capacity waiting for the future demand to materialize.
