Video in Demand
10 Might 2004
Video on Require (VOD) permits subscribers to select from a library of documented films and TV programming, and watch all of them immediately on their TV set, usually via a set-top box. It truly is analogous to using an вЂonline video or DVD store'. Most variations allow the end user to temporarily stop, rewind or perhaps fast forward the plan. The customer compensates a small payment to watch each programme, and has gain access to for a limited time period, generally 24 hours. In contrast to conventional transmit TV, articles is expected by the viewer, hence the service can be вЂon demand'. This account focuses on VOD over DSL or fibre networks, however some examples of VOD over cable connection are included. After many damaging bogus starts, VOD over DSL is beginning look like a viable proposition, for least wherever market conditions are great. Point Matter estimates that as of May possibly 2004 there are at least 230, 000 DSL and fibre subscribers worldwide with access to the case VOD. Various operators are actually pushing forward with ambitious rollout ideas which should consider subscriber quantities over you million within 12 months. Factors behind the bettering outlook consist of:
вЂўSharp falls in the original capex per end-user required to set up VOD service вЂўImproved DSLAM and network technology allowing better and cost-effective distribution of video content material вЂўLower backhaul bandwidth costs
вЂўGreater willingness by film galleries to concur content discounts вЂўPositive reviews from the users of existing services, whom prove to like VOD, are tending to increase their use of that, and are les likely to churn to other service providers if they already have VOD. Taking these factors into mind, business programs for VOD can expect fairly early break-even rather than a extended period of weighty losses. Operators are starting to consider the possibility that a VOD offering may possibly become a vital part of every broadband portfolio rather than a high priced luxury. VOD over wire raises several issues, both equally because the cable industry is already built upon video entertainment and because in the different technological characteristics of broadband syndication over cable networks. True VOD or top-end near-VOD over digital cable television is beginning to see a large level commercial services on a section by area basis. Many cable businesses already present near video on demand, but popular true VOD will require main network expense. It will for that reason happen as an major rather than ground-breaking development of existing services. 2 Key features
