Video Remote Interpreters, or VRI for short, are software which allows for real-time translation of video signals sent from computer systems to a TV receiver. These types of software are used by video rental services, television stations and film and video rental companies to deliver the signal in a format suitable for transmission over the Internet. In other words, these are also called IPTV Interpreters, as they operate on the same principles as older-style analog TV broadcast systems, allowing users to access programs and shows via a television set. vri software offers excellent info on this.
The Vri software is available for both on-demand and off-line services, allowing businesses and private consumers alike to enjoy a wide range of programming, regardless of their location. Off-line providers are able to deliver their signals to television sets across the country using existing broadband connections, while on-demand companies can deliver their digital service directly to homes and business locations using proprietary Internet connections. While both types of companies have similar underlying goals, they differ greatly in terms of features and capabilities, as well as in the delivery method.
Most on-demand providers offer the traditional VCR video cassette to their customers and allow them to plug the resulting analog signals into their computers, through an Ethernet connection, as well as through a digital subscriber line (DSL). Because these providers connect their servers to their TV sets through an existing high-speed internet connection, it is very unlikely that they will experience a problem with a slow or dropped connection. On-line providers who use Vri software do not have such worries, as they connect through a DSL connection or another advanced broadband service, and thus have the luxury of enjoying an almost constant stream of video content, without the need to worry about connection issues. However, as the demand for IPTV increases (there are now more IPTV stations than conventional TV stations in the U.S.), it is becoming increasingly difficult for companies using conventional analog services to deliver video to residences.
