Worldwide the television industry is currently in the process of changing from analog to digital technology. MPEG-2 has now been universally adopted as the main standard for video compression. Since MPEG-2 does not contain all required metadata, an information layer needs to be added to the MPEG in order to transmit it to end users. Standards have been created by industry to provide for the methodology of packetizing MPEG-2 streams and adding encoding information in tables via data packets to the video packets The DVB standard has been approved by the European Community and other industry and government groups as the standard to accommodate the need for satellite and terrestrial originated digital television. This product complies with the DVB ASI specifications as defined in ETSI TR 101 891 and provides for the ability of computers to capture, process, and transmit DVB ASI compliant streams.

THE DVB ASI STANDARD

DVB ASI defines a method of digitally transmitting MPEG-2 Transport Streams at 270 Mbps and is designed to be transmitted via QPSK modulation via a Satellite based Router to the home receiver. It is usually composed of many standard definition 4-6 Mbps streams multiplexed together with associated audio streams in various languages into a Multi Program Transport Stream. This is the standard that is usually used to feed most brands of DVB Modulators. Our DVB Master FD/B device can be used to create inputs and outputs for Video Servers or test equipment that is compatible with the DVB ASI standard.

Clock Issues: The DVB ASI standard specifies a very accurate 30 ppm clock. The cabling for DVB requires a 75 ohm Coaxial Cable with BNC connectors.
