PN: H-ASI-DS3-B Bi-directional ASI to DS3 and DS3 to ASI
DVB ASI is a very common video TS transport stream protocol in the digital video broadcast industry. Many TV studios have DS3 links to the broadcast headend. It is possible to use this link to carry a DVB-ASI stream over the DS3 line at up to 44Mbps.
Often it is necessary to transport these ASI Transport Streams from a studio to a broadcast head end. It is possible to transport the ASI over DS3 connections. The H-ASI-DS3 unit can encode and carry DVB-ASI transport streams over a standard DS3 line. These units are for ASI over DS3 Transport.
These units are for ASI over DS3 Transport in both directions, another words it can send and receive ASI over DS3 lines.
ASI to DS3 and DS3 to ASI conversion is a cost effective solution for DVB signal transport.
It can carry multiple program streams in either MPEG2 or MPEG4 format.
