Bridge Technologies Launch Upgraded Satellite Module VB278
posted:
The base VB120 and VB220 accommodate a range of network standards, including IP unicasts and multicasts, OTT/ABR streams, and a whole range of RF formats, as well as SRT and ASI, offering key monitoring features such as TR 101 290 analysis, IP multicast monitoring, HLS/M-DASH monitoring, TS recording, RF analysis and SRT relay operations. SRT (Secure Reliability Transport) is of particular interest, because it allows for received RF streams to be converted into an IP/UDP stream, which is then made available via the SRT standard. This framework makes it possible to gain central access to streams that would otherwise be hard to access, thus giving engineers greater insight, diagnostic capability and control over their network.
Through the addition of new VB278 module, these probes gain up to four independent RF L-band inputs, which allow for the specific monitoring and analysis of the RF streams found in satellite contribution and direct-to-home distribution infrastructure. With each VB278 module, one input is activated by default, and the other three through software license key. Two VB278 modules can be added to any single chassis, therefore allowing for up to eight independent RF inputs, and through the use of round-robin operation, a significantly higher number of transponders can be monitored overall.

Alongside support for DVB-S, DVB-S2 and DVB-S2X, the VB278 supports QPSK, 8PSK and 8/16/32APSK modulation standards, along with DirecTV and AMC mode support. Configuration of the probe for symbol rate detection – requiring only the input of the frequency by the user – adds to the intuitive and easy-to-use nature of the module, an element common to all Bridge probes. Moreover, the VB278 incorporates a range of monitoring metrics and graphs specific to satellite signal analysis, including Modulation Error Rate (MER), Signal to Noise Rate (SNR), Error Vector Magnitude (EVM), Constellation Diagrams, RS Packet Error, Trend RF graphs, Pilot detection and Energy per information bit/transmitted bit/symbol to noise power spectral density ratio. These are all presented using clear, intuitive, at-a-glance metrics which inform in-the-moment decision making, along with longer term, strategic planning, both in terms of network engineering and business development. All of this data can be accessed from anywhere in the world through any HTML5-enabled web browser.
In addition, the VB278 is future-proofed through the incorporation of an expansion port for hardware add-on functionality, which in the near-future will include a Software-Defined-Radio (SDR) plug-on block which allows for a range of added functions, including waterfall spectrum analysis and I/Q spectrum triggered recording. These expanded functionalities will have importance for areas such as signal interference detection and intermittent fault analysis, and represent Bridge Technologies’ commitment to increasing the range, flexibility, functionality, versatility and capacity of their core monitoring solutions, providing for broadcasters who maintain complex, hybrid and evolving networks.

Speaking of this most recent addition, Chairman Simen K. Frostad said: “Our commitment to IP-based broadcast – a vision we’ve held for 20 years - has been vindicated in the broadcast market. But even bigger than that is our commitment to monitoring in general, regardless of platform. Effective monitoring should constitute the backbone of any network delivery solution, especially those who are taking legacy components and beginning to hybridise them with IP-based standards”.
He continued: “That is why we have developed an extensive range of add-ons for our core VB120 and VB220 probes, including the VB273 for redundancy and the VB258 for the monitoring of DVB-T/T2, ATSC1.0/ATSC 3.0, DVB-C, QAM-B and ISDB-T formats. With these options, alongside the VB278 for satellite, broadcasters are able to create the perfect custom solution, regardless of the complexity and range of their broadcast infrastructure”.
Bridge’s full range of monitoring solutions will be on display at IBC2024, Booth 1.A71.
