DVB Master Quad/i

datasheet for DVB Master Quad/i

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 must be decoded at the same rate it was encoded, 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.

DVB-ASI streams are routinely used to send and receive transport streams between different brands of equipment.  These transport streams can be single program transport streams or multiprogram transport streams.  Interestingly, RF modulators determine the maximum size of transport streams.  QAM modulators can handle 38 Mbps, 8VSB modulators can handle 19.3 Mbps, and DVB-S2 can handle over 60 Mbps.  Of course IP backbones can routinely transfer 100 Mbps transport streams.  It is also worthwhile to note that H.264 streams can be embedded into any MPEG-2 stream.  Our DVB-ASI interface cards can handle them all.
