Acorn Computer Group Plc and Optivision Inc demonstrated their offering for cost-effective delivery of interactive MPEG video for intranet applications at this week’s National Association of Broadcasters’ conference in Las Vegas. The combination of Acorn’s new set-top box, the STB22, and Optivision’s LiveStation MPEG video networking system provides the tools necessary to build and deliver live and stored video over Internet Protocol and Asynchronous Transfer Mode networks, as well as the ability to develop Web-based interactive applications. The process works by using Optivision’s LiveStation to encode the content, such as a live broadcast, and feed the MPEG compressed video either on to a server where it can be accessed, on request, by the user through Acorn’s STB22, or directly to the set-top box. Oracle Video Server gives customers full VCR control of the video content. The Acorn STB22 interactive set-top box features an ATM25 interface, MPEG2 decode capability, a built-in Web browser and support for Java applications. Additionally, the STB22 is available with an Ethernet Interface.
