Scalable inputs and outputs

The number of inputs and outputs is scalable by combining two, three or four modules and a rear panel option that integrates all inputs to all outputs. Unlike cascading, the method of expansion used in the KMX-4911 does not add delay or latency to sources coming from different modules. 4K UHD output capability is available on the KMX-4911 in combinations of two or more cards.


Choice of multiviewer output connectivity options

Rear panels are available with one or two SFP slots. Each SFP slot can be equipped with one of the following SFP output options: SDI coaxial for broadcast monitors, HDMI for displays installed close to the multiviewer, fiber for extending the distance to the display, and SMPTE ST 2022-6 IP to benefit from IP routing to the displays and remote installations. In addition, all multiviewer outputs are returned into the GV Node internal fabric module (IFM-2T) so they are available on the IP aggregation ports, as well as XIO-4901 outputs. The HDMI output SFP option is designed with a latching mechanism to ensure the connection is solid in high vibration mobile environments such as outside broadcast trucks.

Live IP multiviewer platform

The KMX-4911 in combination with the IP aggregation ports of the GV Node IFM-2T offers the ability to build IP SMPTE ST 2022-6 input multiviewers. For example, a multiviewer system with up to 144 3G IP inputs and 32 multiviewer outputs can be designed in a compact 4 RU frame. Multiple GV Nodes can be combined to meet the largest monitoring requirements.

All the features you need for live production

Providing fast, easy and simplified workflows, the KMX-4911 is ready to go with all the features required for production control rooms and outside broadcast trucks. This includes timecode displays, built-in timers, safe area markers, audio meters and tallies from the production switcher. The KMX-4911 also offers multiple levels of UMDs showing both static or dynamic information obtained from the control system, the production switcher or the tally management system. The fast processing time of one field makes it perfect for live production monitoring.

Ready for playout master control and transmission

The KMX-4911 provides all of the advanced probing and metadata extraction for ensuring the quality of your on-air transmission, including specialized features like Dolby-E monitoring, zone-based black and freeze detection.

Large scale and distributed multiviewer systems using COTS IP

Using flexible and increasingly commoditized COTS IP as an infrastructure base, several GV Node frames equipped with multiviewers can be added and combined for greater capacity, meeting even the largest multiviewing requirements. GV Node’s standards based IP inputs and outputs ensure that your investment will be protected into the future.

Highly flexible and scalable multiviewing systems can be realized using COTS IP as the core infrastructure. In the example below, Grass Valley’s IPG-3901 gateways are used to encapsulate SD/HD/3G SDI inputs to SMPTE ST 2022-6 IP in local and remote locations. Sources are then distributed to all KMX-4911 multiviewers using a COTS IP switch. The multiviewer outputs are then returned to the COTS IP switch to be distributed to any display within the facility. At the display, a DXF-300-IP-RX IP to HDMI output converter is used to interconnect with the display. The control of the IP routing is managed by GV Convergent using familiar interfaces such as router control panels and software panels.
