The VB120 BROADCAST PROBE is a blade based platform for continuous digital TV monitoring, its modular concept providing the flexibility needed for a cost-effective surveillance system tailor-made for each operator. System scalability in terms of monitoring capacity, signal formats handled and functionality ensures a future-proof solution, an invaluable asset in an ever changing world.
The ability to continuously measure all your media services makes the VB120 invaluable for confidence monitoring, thus facilitating a more rapid network expansion.
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 DVB ASI, IP monitoring is enabled through the IP Monitoring and Analysis option and RF inputs may be included by adding demodulator blades to the system. COFDM, QAM/VSB and QPSK DVB-S/S2 demodulators are available for use with the VB120.
Each Bridgetech ETSI TR 101 290 engine performs Priority 1, 2 and 3 measurements in addition to monitoring vital CA parameters, CA monitoring being of vital importance as CAS errors may lead to equally severe impairments as ETSI TR 101 290 Priority 1 errors. The monitoring engine may also be configured to check signal scrambling. PSI/SI and PSIP tables are analysed 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. Fully configurable round-robin functionality enables sequential monitoring of several transport streams per monitoring engine.
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 otherwise necessary on-site visits by skilled and expensive engineers. The VB120 recording functionality allows alarm triggered recording from any enabled input.
The IP Monitoring and Analysis Option activates 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 10 IP multicasts. These vital parameters being presented through Bridgetech’s own 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 an IP 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 BROADCAST PROBE hardware is dedicated and built to telco-grade standards for maximum reliability and minimum maintenance. 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 COFDM (VB250), QAM/VSB (VB262) and QPSK DVB-S/S2 (VB270) interfaces.
