DVB Master™ III Rx (PCI 2.2)


Enhanced DVB ASI PCI 2.2 Transport Stream Receive Interface Card with Automatic Packet Conversion, Automatic Null Packet Insertion, Unlimited PID Filtering, and Packet Arrival Timestamping


OVERVIEW
DVB Master III Tx

DVB-ASI is a physical interconnect standard created by the international standardization group known as the DVB Project (www.dvb.org).  It is designed to carry MPEG-2 transport streams between devices at a maximum rate of 213 Mbps.  The actual signaling rate of DVB-ASI is 270 Mbps, but there is overhead from the data encoding scheme and the maximum payload ends up being approximately 213 Mbps.

Transport streams are essentially packetized MPEG streams with tables embedded every 100 ms or so, which tell the ultimate MPEG decoder how to decode the stream.  Furthermore, transport streams may be combined or multiplexed to create multiprogram transport streams with separate PIDs, or program identifiers, that distinguish them as “channels” do in analog television.

We have incorporated as many features as possible into this PCI card.  With all these features, our customers can create very powerful workstations that can process transport streams “on the fly” for applications such as broadcasting, cable TV, satellite links, video servers, and distance learning. 

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.
