BRIDGE Technologies / product option / VB230 RTP reference generator

A further use of the generator module is as a guaranteed fault-free beacon channel. In a real-life turnaround scenario to be found in IPTV systems, the incoming signal arrives from satellite or cable. The input signal can thus contain artefacts that have nothing to do with the IP network. This leads to ambiguity when trying to measure downstream in the IP network. Because the VB230 generates a Transport Stream you can trust, you can quickly eliminate signal related issues as a potential problem source and concentrate on the real problems within the network itself. Ambiguity is avoided completely by making use of the VideoBridge VB230 generator module.

The signal is generated in the head-end where you know it to be fault free. VB230 use is further enhanced by RTP protocol generation inside the generator module.This has the effect of adding a packet sequence counter to each IP frame played out. By generating and monitoring an RTP stream with a packet counter at strategic points in the network the operator gains exact knowledge of potential out-of-order/dropped packet events.

Each generator module runs a built-in web server, providing for easy remote management. Initial setup is performed through RS-232 or TELNET. Central management and alarm reporting are provisioned for via the VBC controller server software.
