VB120

VB120 EMBEDDED IP AND RF PROBE

The VB120 broadcast probe offers a cost-effective and powerful monitoring solution, covering most common signal formats found in any media operation. In particular, the VB120 is capable of monitoring IPTV multicasts, OTT/ABR streams, SRT streams as well as a whole range of RF formats. The VB120 probe hardware platform is custom designed by Bridge Technologies with the key design goals being an MTBF of at least 15 years and a power usage of less than 30 Watts for a fully populated 1RU chassis.

The VB120 probe hardware is custom-designed and built to telco-grade standards for maximum reliability. This makes the solution particularly suited for installations in remote and hard-to-get-to locations with a minimum of maintenance and where there are constraints on air conditioning, power usage and personnel. Each VB120 blade consumes less than 12W of power and is designed for an MTBF of 15 years, thus substantially reducing power consumption and air conditioning needs in installations.

The VB120 can be paired with a full set of interface blades to cover signal formats such as DVB-T/T2, DVB-S/S2/S2X, DVB-C, QAM-B, ATSC1.0, ATSC3.0, ISDB-T and ASI. Up to 13 ASI or RF transport streams can be concurrently monitored in a single 1RU chassis. The ability to continuously measure all your media services makes the VB120 invaluable for confidence monitoring, thus facilitating a more rapid network expansion. Up to 13 ASI or RF transport streams can be concurrently monitored, with options for up to 50 IP multicasts and 50 OTT/ABR streams. Streaming formats supported currently include Microsoft Smoothstream™, Apple HLS™, Adobe HDS™, MPEG-DASH and basic RTMP. 

The VB120 performs deep analysis of the broadcast signals and offers a web-based interface ideal for remote access as well as signal record and relay functionality over IP. This reduces the need to travel to remote locations when changes in the system are made or to find the reason behind alarms. 

The VB120 broadcast probe relies on a 1RU chassis for power and interface capabilities. Each chassis has 3 card bays and the VB120 controller module is typically situated in the left-most bay. There are 4 chassis variants available to suit most installation needs. 

The ACC 1RU chassis option is the most cost-efficient option and offers a single 100-240V AC PSU and 3 fans with air direction from left-to-right when viewed from the connector side.  

The EC 1RU chassis is the preferred choice for redundancy. It offers two 100-240V AC PSU units with separate power inlets, 6 fans with air direction front-to-back, chassis fan and temperature alarming as well as seamless power fail-over switching.  

The two AC models above are mirrored in corresponding –48V DC variants. These are called ECC and EC-DC, respectively. 

RF and ASI input modules

The VB120 can be bundled with up to 2 additional plug-in modules in one 1RU chassis, enabling monitoring of non-IP based signal formats such as ASI and RF. The list of supported standards includes ASI for intra head-end coaxial wiring, DVB-T/T2 terrestrial networks, DVB-C/QAM-B cable-tv networks, DVB-S/S2/S2X satellite DTH infrastructure, ATSC1.0/3.0 terrestrial distribution in the US and ISDB-T as found in terrestrial networks in Brazil and Japan. The monitoring unit is deployed on a standalone basis and accessed through its own built-in web server, or via the VBC Controller in a larger system. The openly available External Integration Interface allows for third-party management system integration such as DataMiner by Skyline Communications.

VB246 ASI Input Module

The VB246 module is designed to provide customers who require high ASI monitoring density with 6 ASI inputs operating in parallel. Monitored concurrently and with continuous ETSI TR 101 290 analysis, the VB246 is ideal for existing infrastructures in the head-end and regional edge-multiplexer/modulator/transmitter sites. Each 1RU chassis supports up to two VB246 modules for a total ASI density of 13 (the last one being local to the controller VB120/220 module). The physical interface is 6 x 75 ohm BNC Female. Each input has a matching red/green signal lock status LED on the card front. 

VB252 DVB-T/T2 terrestrial input module

The VB252 DVB-T/T2 COFDM input module (w/ 1PPS synchronizations) is ideally suited for continuously monitoring the performance of terrestrial distribution networks. Typical usage includes transmitter tower monitoring where the monitoring probe is co-hosted with the RF Exciter. Alternative usage is as a standalone off-air monitoring probe capable of receiving the signal from multiple transmitters operating in SFN in fringe coverage areas. The VB252 plug-in module supports one DVB-T/T2 COFDM RF input by default. The second input can be activated by the customer via a software licensing option. A chassis can be equipped with a VB120 probe controller that has one or two VB252 RF input cards under its control, for a maximum of 4 independent RF input ports. Full ETSI TR 101 290 analysis is performed on all active RF inputs. The Advanced RF Option adds impulse response graphing and analysis to the VB252, making it possible to check reflection conditions at the probe location. Configurable threshold limits determine when an alarm should be raised due to reflection changes in time or power. Impulse response analysis results are presented as a user-friendly graphical GUI, facilitating reflection measurement interpretation.

VB256 ISDB-T terrestrial input module

The VB256 ISDB-T input module expands Bridge Technologies’ digital terrestrial monitoring capabilities to encompass the Latin American and Japanese terrestrial markets. Supporting both ISDB-T/SBTVD-T standards, it enables customers operating in these regions to fully monitor their ISDB-T transmissions. A chassis can be equipped with a VB120 probe controller that has one or two VB256 RF input cards under its control, for a maximum of 4 independent RF input ports. Full ETSI TR 101 290 analysis is performed on all active RF inputs.

VB258 terrestrial/cable RF

The VB258 offers 4 independent RF inputs that allow for monitoring and analysis of RF streams as found in terrestrial and cable architectures, with the system facilitating one RF input by default, and the other three by license activation. Formats supported are DVB-T/T2, ATSC1.0/ATSC3.0, DVB-C, QAM-B and ISDB-T. Up to two VB258 modules can be placed into a single chassis for 8 independent RF inputs. Each RF input is further capable of round-robin operation to allow for monitoring of a full frequency raster, as typically found in DVB-C/QAM-B cable networks. The VB258 complements the VB120, 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. This latter feature – SRT relay operation – is of particular interest since it allows for the conversion of any received RF stream into an IP/UDP stream, which is then made available via the SRT standard. SRT (Secure Reliable Transport) allows for reliable UDP streaming across Internet-type media, and through this it is possible to gain central access to streams that would otherwise be hard to access.

VB262 digital cable

The VB262 Dual QAM/8VSB input option offers monitoring of cable TV signals as found in ITU-T J.83 Annex A/B/C QAM networks and 8VSB signals found in ATSC1.0 terrestrial networks. The VB262 plug-in module supports one RF input by default. The second input can be activated by the customer via a software licensing option. A chassis can be equipped with a VB120 probe controller that has one or two VB262 RF input cards under its control, for a maximum of 4 independent RF input ports. Full ETSI TR 101 290 analysis is performed on all active RF inputs.

VB272 Satellite input module

The VB272 input card offers monitoring and analysis of QPSK/8/16/32APSK signals found in DVB-S/S2 satellite Contribution and DTH networks. Each VB272 module has one RF input activated by default. The second input is activated through a license key option. Each chassis can be equipped with a VB120 probe controller and up to two VB272 input cards under its control, for a total of up to 4 independent RF inputs. Full ETSI TR 101 290 analysis is performed on all active DVB-S/S2 inputs. Each RF input has a built-in antenna 13V/18V drive and 22kHz tone control. DisceqC 1.0 switching is supported.

Redundancy switching modules

The option for redundancy switching on the VB120 enables 2:1 A/B-style redundancy switching to take place based on alarms from the full TR 101 290 specification and not only basic parameters such as signal loss or carrier sense. Two supporting modules – the VB243 and VB273 – are available, offering relay switching on ASI-type signals and L-band or IF satellite style signals respectively. Applications include main/backup redundancy switching at terrestrial TV towers or at satellite uplink facilities. The switching blades listed contain bi-stable relays, making them capable of maintaining the switching state even without any power applied to the system.

VB243 ASI Intelligent redundancy switch

The VB243 provides full dual-path redundancy for ASI signals with autonomous operation and deep signal analysis on both signal paths for the ultimate switching decision making. Front panel controls with illuminated buttons offer local override control and a clear visual indication of the active switching path. The redundancy switch offers three distinct modes of operation making it suitable for any real-life operational challenges: automatic, manual and SuperLocal.

VB273 Intelligent Redundancy Switch

The VB273 Intelligent Redundancy Switch also provides full dual-path redundancy autonomous operation and deep signal analysis on both signal paths, but operates in the context of Satellite operations. The solution is ideal for providing fast and robust redundancy switching for permanently installed satellite up-links or in outside broadcast systems. As with the VB243, front panel controls with illuminated buttons offer local override control and a clear visual indication of the active switching path, and also operates on an automatic, manual and SuperLocal basis, as required - making it suitable for any real-life operational challenges. The VB273 comes in two factory-ordered variants, depending on whether the input signal is 70MHz IF or L-band.

QoE & QoS content monitoring

In the connected media consumption landscape, there exists a vast amount of data that needs to be understood – and acted upon. These volumes of data need exceptional analytical tools if the data is to make sense, and the VB120 hardware probe provides exactly this: in-depth analysis for detailed understanding of data for error, jitter, dropped packets, latency and low throughput analysis, producing hard, empirical QoE & QoS data – without the false positives.

QoE Content monitoring

What matters to audiences is their ultimate user experience, not the technicalities of network performance. As such, unlike many monitoring solutions in the market, the solutions from BRIDGE Technologies place a deliberate focus on establishing the end user’s Quality of Experience (QoE). QoE functionality involves audio/video content extraction and processing techniques such as MOS average, VMAF scoring, freeze-frame/color-freeze error, audio level and stereo phase detection and real-time audio loudness monitoring. This functionality is mainly reserved for the VB330/VB220 and software/appliance-based products in the portfolio and not the VB120 embedded solution. However, the VB120 also has some QoE functionality in the form of a thumbs mosaic available for all streams extracted as well as a straightforward thumbs freeze-frame detection algorithm included. 

QoS monitoring at the IP and TS level

Regardless of whether the video in question is multicast, unicast (OTT/ABR), carried over IP or ASI, through a CDN or directly, and irrespective of compression and TS standard employed, the VB120 incorporates tools necessary to monitor specific attributes of each type of cast – with insight generated at the IP, TS and Content level. Quality of Service (QoS) monitoring represents the backbone of a comprehensive monitoring solution – understanding network performance along the full media chain; from point-of-origin, through the CDN and across the final mile: uptime, downtime, error rates, bandwidth, latency, profile switching alignment – QoS ensures that network movement is occurring within established parameters, and provides the data that engineers need to identify problem points and engage in strategic improvements.

Patented Visualisation

The VB120 contains unique visualisation technologies such as the MediaWindow™ and the microETR™. The MediaWindow allows the operator to gain key knowledge about the carriage quality of the media multicasts over time selectable time intervals. Color-coded graphs give an intuitive feel for how well the signal behaves in terms of QoS parameters such as packet loss and packet jitter. The microETR™ deals with transport streams and allows for the real-time alarm state of hundreds of media streams to be viewed in a single view. This allows for faults to be spotted and pinpointed in seconds. Together these techniques result in a graphical user interface that is packed with essential information, yet intuitive and easy to read.

MediaWindow™

Multicast Monitoring

An extensive range of multicast parameters can be displayed at-a-glance, pertaining to IP, TS, Ethernet, RTP and FEC. Associated thumbnails are also displayed, which can be expanded to produce a more frequently updated single image – or alternatively, display error information in cases where thumbnails cannot be obtained. For each multicast stream, peak and aggregate values for an extensive range of signal, bitrate and packet data are all displayed, up to a duration of four days, customizable according to the user’s priorities. The detection and joining of multicasts into the probe is also facilitated in an intuitive and simple-to-achieve manner. Both IPv4 and IPv6 are supported.

Traffic - Microbitrate Bursting

A common problem in any large enterprise or public network infrastructure is the occurrence of packet bursts. These typically happens due to congestion points and resulting packet queues accumulating inside the Ethernet switches and IP routers making up the network. When the network is used to transport video these aberrations can have a particular adverse effect. This unique functionality allows the network engineer to detect the amount of micro bursting and also trend this over time to spot patterns otherwise very difficult to pinpoint. Microbitrate burst monitoring is available on the VB120 through a software license option called Advanced Ethernet Option that in addition also offers PCAP capture and multicast VoD monitoring.

SRT contribution and cloud monitoring

Bridge Technologies is a proud member of the SRT alliance, and recognizes the value that this robust quality, low latency, open-source video streaming protocol presents to the industry. The VB120 can receive up to 4 SRT streams and forward them to the main monitoring framework for further analysis. This includes MediaWindow visualisation, TR 101 290 analysis, content capture and thumbnail mosaic. Key parameters such as round-time and lost-packets are displayed. The VB120 can also send out any two media streams currently being monitored by the probe as an SRT-formatted stream. This capability is typically used for ad-hoc transport of content across an IP network for remote live viewing or recording. SRT support is a standard feature on the VB120.

Customisable Alarming and visualization

The VB120 does not simply display in-the-moment network data to network engineers, but allows for the full customization of alarms, thresholds and parameters across nearly every measurement metric available. This allows engineers to prioritise issues and manage their network in the way that best suits their needs. Alarm customization is easy and intuitive, and the readouts simple to understand, and capacity for alarms of different types is maintained independently – with each group maintaining no bearing on the capacity of another; this includes 100 Full Service Monitoring and Microbitrate (FSM), 2500 OTT alarms, 10000 ETR290 alarms, and 2500 System alarms. A further 20000 alarm entries can be stored in non-volatile memory by employing the FLASH32-OPT. This is particularly useful in remote applications where logging all alarms is important but at the same time the management network connectivity is not always reliable. 

Testing according to ETR290

TR 101 290 testing ensures that the interoperability parameters of TS streams – including intervals, section gaps and tables – are all met. The VB120 has a capacity of 50 concurrent ETR290 engines. It groups errors into Priority 1, 2 and 3 errors, but further allows for the user to fully customize alarming and adapt the thresholds of various ETR290 components.

Gold TS Protection™

Gold TS protection represents an upgrade on the established TR 101 290 standard, including testing for critical conditions that are not covered under ETR290 testing, whilst also making fault tracking much faster, more accurate and secure. It includes identification of failures – all of which are vital real-world quality assurance elements that have direct effect on end-user subscribers. For operators of digital media services Gold TS saves significant time in setup and diagnosis. Easier setup is facilitated through the use of a much faster calibration process than that associated with ETR290, by capturing an ideal transport stream and setting this as a reference value. Easier diagnosis is achieved by reducing the huge volumes of data that technical staff are required to wade through, instead replacing this with quick flagging and clear presentation of the error condition with deviation from protection values highlighted, and side-by-side presentation of correct values. The result is a reduction in time- to-resolve errors of a factor between 10 and 15: meaning Op-Ex is reduced by allowing maintenance staff to effectively monitor larger numbers of streams, whilst quality and reliability of service delivered to subscribers is significantly enhanced.

IAT - Histogram

The Inter Arrival Time (IAT) histogram gives you a view of how well the timing of the media multicast received is over time. It shows an accumulated count of the number of IAT measurements that fall within each presented bin interval. Vertical green lines indicate the maximum and minimum IAT values observed. The user can customize the scales.

Return Data Path

With the advent of fully duplex technologies as IP transportation, new features for allowing remote access to regional ingress signals are vital. Return Data Path allows the operator to record video locally on the probe or re-route live video monitored by the probe to a central location for decryption and further analysis. Recording is initiated either directly by the operator or automatically based on pre-defined alarm trigger criteria. RDP reduces the need for truck rolls and otherwise necessary on-site visits, by making available centrally signals that are normally only available locally. RDP™ also facilitates a simpler descrambling process for scrambled signals, by transporting the stream to the NOC, head-end or anywhere else for visual monitoring. Currently supported protocols for remote relay include UDP and RTP uni/multicast and Secure Reliable Transport (SRT).

OTT/ABR monitoring

The VB120 incorporate powerful OTT/ABR analysis engines for gaining insight into any adaptive bitrate video distribution, particularly in VoD and Live. Supported formats include HLS, MPEG-DASH, CMAF,  SmoothStream, HDS, basic RTMP and Shoutcast for radio. Each OTT Engine operates autonomously and only requires knowledge of the URL from which the media is being fetched. The OTT Engine then parses the manifest file provided by the origin or edge-server, extract the different profiles served, validates syntax, checks chunk counters and then does the same for the individual profiles. Support for AES-based decryption is included as well as an innovative method for customizing the expected format of the manifest files received.  

Thumbnails

As with the multicast and RF/ASI monitoring functionality, thumbnails for every OTT channel are displayed if successfully descrambled or available in the clear. These thumbnails can then be clicked through to for each profile, along with associated data (actual bitrate, expected bitrate, etc) of each profile. Thumbnail update rate is dependent on compression standard and resolution and can be adjusted by the user.

Origin server CDN monitoring

he maximum number of OTT/ABR streams for the VB120 platform is 50 and is available through software licenses that can be activated by the user. There is no practical limit on the number of bandwidth profiles supported within one OTT/ABR stream.

SCTE-104 and SCTE-35 Marker Monitoring

The capability of monitoring ad inserts is of particular importance to safeguard the revenue flow of any media operation relying on commercials as an income. Advertising breaks are typically signalled using either the SCTE-104 (uncompressed) or SCTE-35 (compressed) standards. These standards describe messages – or events – that flow together with the main signal telling downstream equipment when to switch in and out advertising content. By adopting the additional SCTE35-OPT, the VB120 can support for monitoring SCTE-104 carried inside ST.2038 or SCTE-35 directly in all the IP and ASI/RF transport streams monitored as all the activated ABR/OTT unicast streams. Events are logged internally in the probe and also visualised in the content timeline view. Relevant alarms are generated in case of erroneous syntax or mismatching timing.

Security — Tacacs+

The VB120 uses best practices from the IT industry to ensure continued operational stability and the highest level of protection against attack. The VB120 ensures continued operational stability using HTTPS to secure and encrypt the communications channels, thus practically eliminating the possibility of man-in-the-middle attached. This provides broadcast facilities with the ability to architect and use IP broadcast capabilities with confidence and ease.

IP-OPTION
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.

AEO-ADVANCED ETHERNET-OPTION
Advanced Ethernet option enables continuous monitoring of streams, whether they be VoD streams or any continuous stream that can be classified by the built-in advanced filters. Complete MicroBursting detection and monitoring capability together with PCAP recording are also included in this option.

STREAM-OPTION
This option increases the number of IP streams continuously monitored in from the built-in 10 IP streams up to 50 IP streams in 10 stream increments.The ability to increase the number of streams in the VB120 gives great investment protection should the need arise for more services to be monitored. Up to 50 streams can be purchased in increments of 10 streams. The streams increase can either be purchased and factory preinstalled or the unit can be upgraded via a simple software upgrade remotely in the field.

T2MI-OPTION
The T2MI-OPT applies only to the management board.
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 T2MI option makes it possible to design and implement an end-to-end monitoring system for DVB-T2 distribution.  The T2MI option extends ETSI TS 101 290 analysis functionality of a Bridge Technologies probe to include inner streams in DVB-T2 distribution systems where T2MI functionality is used. The T2MI stream-in-stream concept opens for simplified local insertion and is increasingly being used in DVB-T2 distribution. Monitoring of signal integrity is essential, and the T2MI probe option makes it possible to check inner stream parameters, like T2 timestamps and L1 information. Measurements are performed real-time in accordance with DVB document A14-1.

ETR290 (ETSI TR 101 290)-OPTION (Included)
The ETSI TR 101 290 functionality is included as standard on the VB120. ETR290 also available as an option on the VB20 and VB220. Full analysis is performed on Ethernet, ASI, COFDM, QAM, DVB-S/S2 QPSK and signals according to the industry standard ETSI TR 101 290. Multiple analysis engines are available as an option for Ethernet, allowing real-time ETSI TR 101 290 analysis for Ethernet transport streams in parallel. The Bridge Technologies implementation provides operators with unparalleled input signal visibility. The probes can detect and trigger alarms for many of the common errors that would normally go unnoticed by conventional monitoring systems.

BULK-ETR290 (ETSI TR 101 290)-OPTION
The ETSI TR 101 290 functionality is included as standard on the VB120. ETR290 also available as an option on the VB220 and VB330. Full analysis is performed on Ethernet, ASI, COFDM, QAM, DVB-S/S2 QPSK and signals according to the industry standard ETSI TR 101 290. Multiple analysis engines are available as an option for Ethernet, allowing real-time ETSI TR 101 290 analysis for Ethernet transport streams in parallel.

OTT ENGINE-OPTION
The use of OTT technologies like variable bit rate HLS, SmoothStream and HDS for distribution of media to all kinds of receiving platforms is rapidly expanding, portable devices used in multiscreen applications being particularly important for OTT deployment to be a preferred method for media signal delivery. Content distribution using OTT is complex, and it is necessary for a service provider to perform continuous surveillance of signal availability and integrity of both LIVE multi-profile streams and VOD content.  The OTT Option provides the same paradigms as more traditional media transports enabling easy understanding of complex media transportation where operators have both traditional and new distribution systems. The OTT options, available for all Bridge Technologies probes, enables monitoring and analysis of HLS, SmoothStream, HDS and MPEG-DASH streams. The OTT engine will check that stream and profile manifest files, the «lists of contents», are syntactically correct and updated, that all stream profiles are available and that stream chunks are delivered on time.

SCTE35-OPTION
SCTE35 is a specification which allows equipment to splice in local content at specific times. SCTE35 is the signalling mechanism the equipment uses to know when to switch from the master transmission to insert local content and when to switch back. SCTE35 is used for two different reasons: In USA it is used to insert local advertising. It’s quite common that local Cable TV companies redistribute satellite channels in their network. They can purchase the right to replace some of the country-wide advertising with local ads. In Europe it is used to insert local TV programs, e.g. local news transmissions. SCTE35 analysis requires a special license for the probes and is connected to the ETR290 engine. All streams where ETR290 monitoring are performed simultaneously can be SCTE35 monitored in parallel, i.e. this is a reason for buying VB330 if many SCTE35 streams are to be monitored in parallel. GUI: From the ETR 290 main tab a list of streams containing SCTE35 signalling are displayed under the SCTE 35 tab.

FLASH32-OPTION
The Flash32 feature is used as an added 32GB SD card, to be able to save RDP and PCAP recordings. RDP recordings are automatically moved to the SD card when completed, and PCAP recordings can be manually moved using the interface GUI as shown below. When in the storage tab, file system statistics are shown to the right and files can be downloaded by clicking its name.
