Using the DVB-ASI Feature

DVB-ASI capture capability is used for satellite, program distribution, telco and cable

scenarios. The Osprey DVB-ASI feature is available for the Osprey 815e/825e/845e capture
cards. DVB-ASI transports MPEG-2 video streams, primarily for television applications over
coaxial cable, at up to 270 Mbps. The ASI carrier transport can contain different bit-rate single
program transport streams (SPTS) or multi-program transport streams (MPTS) simultaneously
up to the payload capacity of the link. These streams can include private data, control, and
other media information, formatted in an MPEG-compliant structure.

Note: The Osprey capture card must be branded to support this feature. Cards purchased after July1, 2014 will be

delivered already branded.
