The VB120 modular BROADCAST PROBE is designed for continuous digital TV monitoring. System scalability in terms of monitoring capacity, signal formats handled and functionality ensures a future-proof solution. The ability to continuously measure all your media services makes the VB120 invaluable for confidence monitoring.
The VB120 BROADCAST PROBE comprises a fully-fledged ETSI TR 101 290 monitoring engine used to monitor enabled inputs, one monitoring engine per input working in parallel. The basic VB120 monitors ASI and IP. DVB-T/T2, 8VSB, QAM and QPSK DVB-S/S2 demodulators are available. The VB120 performs Priority 1, 2 and 3 measurements. The monitoring engine may also be configured to check signal scrambling. PSI/SI and PSIP tables are analyzed and presented as table summary and hex dump, the latter enabling analysis of proprietary descriptors. Bitrates are measured at TS, service and PID level, and the ETSI TR 101 290 engine also monitors RF parameters for optional demodulator inputs.
The innovative RDP technology (Return Data Path) is one of the advanced features of the basic VB120, enabling easy re-routing of remote signals from regional locations into a central location for decryption and advanced signal analysis. RDP reduces the need for truck rolls and on-site visits by skilled and expensive engineers. The VB120 recording functionality allows alarm triggered recording from any enabled input.
The IP monitoring features optical and electrical Gigabit Ethernet interfaces for connection to the video segment. The VB120 has been designed to support all modern encapsulation standards including ISO/IEC13818-1 Transport Streams and MFRTP. The VB120 continuously measures signal loss, packet loss and packet jitter for up to 50 IP multicasts, these vital parameters being presented through a patented MediaWindow™. MediaWindow™ allows for current and historical data to be displayed in an intuitive and visual way for easy understanding of the media flows in the network.
Alarm handling is one of the main tasks of the VB120 BROADCAST PROBE, and all measurements are checked against user defined thresholds for alarm generation. A sophisticated threshold
template system gives the user full alarm handling control at probe, TS, service and PID level, ensuring that only relevant alarms are displayed.
Management and control for the basic VB120 is available through a separate 10/100 Mbps Ethernet interface, the IP-enabled VB120 may alternatively be managed in-band through the GigE video interface. Standalone access is achieved through the use of a standard web browser, avoiding the need for a dedicated client application. With SNMP trapping and XML export the VB120 IP-PROBE is easily integrated into existing NMS systems either directly or through the optional VideoBRIDGE Controller (VBC).
The VB120 is hosted in a 1RU 19” chassis, each 1”RU chassis capable of hosting up to 3 x VB120 modules, or any combination of the VB120 with six-port ASI (VB242), DVB-T-T2 (VB252), QAM/8VSB (VB262) and QPSK DVB-S/S2 (VB272) interfaces.
