The Thales Sapphire MPEG-2 video server has passed a series of tests by CableLabs for the SCTE 30 2001 specs for digital program insertion (DPI). The compliance tests were part of CableLabs' Phase 9 DPI testing in March.
Cable operators and TV broadcasters use DPI because it allows program substitution in the MPEG-2 compressed domain for advertising insertion and regional program substitution.
For legacy systems, Sapphire uses an ASI interface to send compressed content to the MPEG transport stream splicer. In addition, the server has an Ethernet interface on splicers that support this interface.
The Southwick, Mass.-based company's DPI product line includes an SCTE-35 cue tone inserter, DVS-525 adapter and a DPI cue tone monitor.
