Scalable inputs and outputsThe 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-4921 does not add delay or latency to sources coming from different modules. 4K UHD output capability is available on the KMX-4921 in combinations of two or more cards.
Choice of multiviewer output connectivity optionsRear 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 2022-6/2110 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 platformThe KMX-4921 in combination with the IP aggregation ports of the GV Node IFM-2T offers the ability to build IP SMPTE ST 2022-6/2110 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 productionProviding fast, easy and simplified workflows, the KMX-4921 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-4921 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.
High Dynamic Range (HDR) processing for accurate monitoring experienceIntroducing high dynamic range (HDR) and wide color gamut (WGC) into a live production workflow adds a challenge for accurately viewing these sources on a multiviewer. Without an HDR capable multiviewer, the image will appear saturated, details are washed out, and colors are incorrectly reproduced. Adding HDR/WCG processing on the multiviewer provides the ability to correct this and provide a more accurate image, more HDR-like, on regular SDR displays. The KMX-4921 provides HDR and WCG processing for HLG, PQ and S-Log3 HDR format, and BT.2020 WCG. Each input is individually configurable which allows to mix and match SDR and HDR sources, as well as different format of HDR, on the same display.
Large scale and distributed multiviewer systems using COTS IPUsing 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.
