- A range of cast aluminum mounts; enabling quick operational use of the web interface through tablets in OB Vans and IP studios, alongside PCs typically used for pre and post-event system configuration.
- The VB440 is a Bridgetech appliance custom-built server based on selected processor and network interfaces - 1RU rack mount - 2 x 100Gb/s interfaces - Dual Ethernet 10G, 25G, 40G, 50G and 100G links with dual 40GBit analysis bandwidth The VB440 is designed to perform following key functions; 1. Monitoring, 2. Analysis & Presentation 1. The VB440 can monitor up to 80 Gbps, supporting ST2110 and ST2022-6 network protocols 2. The VB440 can provide analysis of up to 8 services simultaneously: video, audio and colorimetry of Uncompressed SD, HD, UHD and even 8K ! Provides presentation of up to 8 services (fast encode to low bitrate versions) Supports NMOS standards IS-04/05: Multiple Receivers for RTP-based streams(Video, Audio, Anc) IS-07: WebSocket Senders for PTP and Signal measurements IS-09: Automatic configuration of default PTP domain and timeouts
- So,
- Many new studios are basing themselves around IP based technology. Program Control Rooms, Main Control Rooms and OB Vans are selecting IP for scalability, flexibility, future-proofing and, ultimately, cost. The main architectural difference is the move from a Left-to-right SDI based network and functional workflow, to a star-based technical architecture that enables control and data on the same network, and any-where-to-anywhere data streaming.
- The main advantage of using IP in live events is the ability to ‘Separate’ the Acquisition and production teams. With the VB440 monitoring the 100G networks at both sites, stream sources, network performance and destination receivers are easily accessible by engineers. Key aspects here is the network engineer is looking to understand network behavior, as opposed to service impacting errors. By understanding network behavior, and noticing change in this behavior, engineers can proactively maintain their network to ensure service affecting issues do not occur.
- Playout environments are also starting to take advantage of high bandwidth networks to streamline the process from asset storage to playout. By moving uncompressed video through processes that were traditionally performed on compressed media, such as ad insertion, regionalization, the complexity of the playout environment is reduced, increasing flexibility and future compatibility. The VB440is a perfect fit for this environment and can be coupled with Bridge Technologies’ range of compressed media monitoring probes to create a full end-to-end video service monitoring system.
- So,
- The VB440 ‘Instrument View’ is the key analytical interface for network and studio engineers. Interface view is web-based, very high speed presentation using web sockets technologies, simple, intuitive and responsive, Engineers can perform general setup, check stream status, network performance, information about video, audio and ancillary data streams. Key benefits Allows the production team to see the uncompressed media content from any location within or outside the facility analyzing packet behavior to identify network issues, colometry measures to identify source issues We will go through the details more during the demo / screenshots
- The VB440 ‘Expert View’ is the key setup and monitoring interface - Screenshot on the left is showing the monitored streams and any alarms, up to 80Gbps of traffic monitoring. - Screenshot on the Right showing current and historical alarms. These will be used to create historical reporting after an event is completed. We will go through the details during the product presentation.
- The VB440 also has APIs to enable extraction of key measurements, information, low resolution versions of the video streams, and audio stream. The Left Hand Side shows a Bridge Technologies ‘Widglet’, specifically designed as a color shader position. The Widglet is a HTML web page hosted on the VB440 making use of websocket technologies to present five camera streams and their colometry / vectorscope displays along the bottom. This enables a full-motion, color accurate and ultra-low latency video monitoring capability to any location or any application. How Widglets work: Widglets html page 1. connects to the Riedel SmartPanel and subscribes to actions coming from the panel's "Levers" and "Rotaries". 2. configures Riedel SmartPanel to use VB440 as a data source for panel's "Labels"-display and "Lever LEDs". 3. receive actions from the panel(lever switches, rotary movements), and sends feedback(new "Labels" values and "Lever LED" colors) via VB440 back to the panel. 4. gets different video/vectorscope/audio/captions content from VB440 based on the actions coming from Riedel SmartPanel. The Right Hand Side shows a custom MCR orchestration system which has integrated key network performance metrics from the VB440 into their display using NMOS IS-07. In this example the Path delay and IAT of the video and audio streams on a small network is compared. The VB440 will have an open interface to enable MCR orchestration platforms to access VB440 measures.
- This is an example of the widglet AP being used in an OB Van’s Camera Painter Position. The Widglet is integrated with IP based switching interfaces, such as Riedel’s smartpanel, and Skaarhoy’s Remote Camera Painter products. The Smart Panel dynamically modify the web page, enabling fast presentation of the selected camera view (at the top), selection of the vectorscope presented, and as audio volume control. Main benefits; Camera Painter able to simultaneously view all 4 camera pictures Side by side comparative analysis of waveforrm enables simple color matching.
