Introducing DVProbe-C

Modern cable network spanning large geographic areas often multiplex local content together with national program feeds to provide greater programming diversity that caters to local interests. This practice can result in a large number of channel lineup configurations - eg having different channel numbers for the same movie channel in different cities.

Furthermore, since merging local and national content is usually done at remote, unattended facilities, there is a further risk that mistakes can be made. Effective monitoring is essential to ensure the broadcast stream meets engineering expectations. Embedding a fully featured, remotely controllable MPEG stream analyzer into the network is the best way toresolve problems quickly and avoid expensive truck rolls.

The Pixelmetrix DVProbe-C is the ideal preventative monitoring and operational debugging tool. It connects directly to the QAM RF cable network and uses the award winning Pixelmetrix DVStation transport stream analysis technology. Packaged as a 1RU rack-mount system with power, network and RF input connections all on the back of the unit, it integrates easily even into space-conscious environments.

A flexible software-based system built on open standards, the DVProbe-C can evolve with the network as digital cable systems move towards technologies like SDV and beyond.
