The VB220 PROBE is the flagship monitoring platform for all applications in any network where digital video is carried across an IP infrastructure. Built specifically to high-end industry needs, this network service tool is ideal for both pure IPTV networks and hybrid networks with IP transport cores (such as digital cable and terrestrial networks).
The ability to monitor continuously 260 streams makes the VB220 blade just as powerful as its portable version, the VB20. 3 x VB220 blades can be placed in one 19″ 1RU chassis, giving a total of 780 streams monitored in a small form factor. With full support for both the MPEG-2 TS and MFRTP encapsulation standards carrying all modern coding formats, the VB220 is perfect for network core and region use. This is an invaluable helpmate for any network engineer attempting multicast detection on multiple VLANs or in the process of IGMP tracking. Fault finding in complex IP networks just got a lot easier.

The monitoring of critical parameters such as loss distance measurements and detailed jitter values will give operators invaluable and precise feedback of network performance. With the patented MediaWindow™ historical data can be easily accessed for meaningful visualisation of media flow in IP networks. Whether establishing or modifying service settings on complex routers and switches, the VB220 facilitates the whole process.

The power of confidence monitoring is further enhanced by continuous monitoring and alarming for vital parameters like bandwidth overflow/underflow, RTP errors and signal loss. Based on a highly sophisticated threshold template system alarm granularity can be set to reflect actual status, irrelevant alarms being effectively masked. The unique FSM™ framework also allows checking and continuous monitoring of middleware and network services vital to customer QoE.

The VB220 may be used with optional demodulator interfaces, resulting in a very compact monitoring solution particularly suited for systems that use IP distribution to regional nodes. The VB220 monitors IP, ASI and optional demodulator inputs simultaneously, and the transport stream and service compare mechanism makes it easy to validate correct local insertion at regional head-ends.

SNMP trapping and XML export enable the IP-Probes to be implemented in any NMS system with alarm generation; either directly from the probes themselves, or via the VBC server for advanced alarm correlation and filtering. Each VB220 contains the Eii (External Integration Interface) API for seamless and easy integration into any 3rd party system.

Each IP-Probe runs an HTTP server with the client as a web browser, so no need to install custom software on computers needing access to the measurement data. Modern web 2.0 techniques such as AJAX are used to facilitate advanced interface behaviour in a standard web browser.


This option contains full ETSI TR 101 290 monitoring and analysis. One ETR290 engine is standard on all of the VB1 series and additional ETR290 engines may be purchased up to a maximum of four on the IP input. ETR290 is optional on the VB2 series and up to four ETR290 engines can be purchased per IP input.
The T2MI option is used to enable analysis of inner streams in DVB-T2 distribution systems utilising T2MI functionality. Stream verification is based on the renowned Bridge Technologies ETSI TS 101 290 analysis engine, and the T2MI enabled probe allows a thorough check of outer and inner streams.
The OTT option, available for all Bridge Technologies probes, enables monitoring and analysis of HLS, SmoothStream and MPEG-DASH streams. The OTT engine will check that stream and profile manifest files are syntactically correct and updated, that all stream profiles are available and that stream chunks are delivered on time.
