Unmatched Picture Quality and Display Elements

Picture Quality
The Kaleido multiviewers system offers unmatched picture quality — irrespective of picture size — using Grass Valley’s polyphase scaling technology. Windows can be resized all the way from very small windows up to full screen display, without the loss of definition that is commonly associated with multiviewers. This high performance, combined with superior on-screen graphics, makes Kaleido ideal for the most critical monitoring applications.

Audio Meters
Kaleido multiviewers can display four group, 16 channels, multichannel audio for multilingual and 5.1 applications. Audio level meters are extracted from analog, AES or embedded signals, and can be positioned inside the video window in transparency or outside. Ballistics and scales are configurable, and a phase correlation meter can be displayed with each pair. Dolby E audio can be extracted from an embedded audio signal for on-screen metering. An audio meter can readjust itself based on inserted Program Configuration metadata.

Automatic Aspect Ratio control and Safe Areas
Aspect ratio and safe area markers can be positioned over video windows to simplify multiformat monitoring. Free form safe area markers, based on a user’s bitmap, can be overlaid on top of each video window. This feature is useful to protect graphical or branding that will be applied downstream after production.
The processor can automatically change a signal’s aspect ratio between 16:9 and 4:3, based on the Active Format Description (AFD), Wide Screen Signaling (WSS ) or source resolution. Image formatting rules are followed during conversion, including letter/pillar boxing and resizing/cropping.

Dynamically Updated UMDs
Text labels (UMDs) can be displayed inside or outside windows, and updated by a UMD controller. Dynamic text can be driven by NVISION and many third-party routers, and by some automation vendors. Kaleido multiviewers also offer a serial interface for leading production switchers, which provides tally updates as well as sources and destination labels. Text fonts are flexible and support UNICODE for multilingual texts

Clocks and timers
Multiple analog and digital clocks/timers (with date) can be displayed with programmable offsets and configurable colors. The clocks/timers can be driven by LTC, referenced internally, or to an NTP server. Each input module features one LTC input.

Signal Validity Monitoring
The following parameters can be detected and presented on-screen, or reported to SNMP-based signal and facility monitoring systems, including Grass Valley’s iControl systems:

Video Probing
  • Video black
  • Video frozen
  • Video level too high
  • Loss of video
  • EAV /SAV error
Audio Probing
  • Audio silence
  • Audio overload
  • Audio mono
  • AudioOUT of phase
Metadata Monitoring
  • XDS data including V-Chip rating
  • Closed captioning and teletext (608, 708 and WST 42 and 47) is presented in the format seen by television viewers in their homes
Probing points can be configured with different thresholds, and a specific probing zone within the video can be configured for the freeze and black detection.

Display of Closed Captions, Subtitles, XDS and Dolby E Metadata
Closed captions and subtitles are presented in the format seen by television viewers in their homes. XDS data, including V-Chip information, can also be overlaid in each video window, along with the Dolby E metadata, AFD/WSS formats, and audio/video signal format.


Remote Control of Integrated Routing and Multiviewer Systems

Integrated multiviewer and routing systems can be controlled using a choice of remote control panels. One simple option is to use a traditional router control panel to assign any source, anywhere, any number of times on the monitor wall. This mimics what the router would do to a traditional monitor wall, by allowing the user to assign any source to any destination. This type of control is available with the NVISION control panels (shown below), as well as third-party router control panels from Snell (Pro-bel) and Nevion.

The highly graphical RCP-200 touchscreen remote panel offers more advanced control of combined multiviewer and routing systems. The panel provides multiviewer layout pre-set selection, and quick router source assignment control via a category/index graphical interface. The RCP-200 is a multifunctional panel, and can also be used for control of Densité Series interfaces.


Intuitive control across multiviewers
Kaleido multiviewer systems can be easily controlled by one or more dedicated remote control panels, or by an on-screen mouse control.

Simple to use, on-screen mouse operated drop-down menus are contextual to speed operations, and offer numerous functions, such as changing aspect ratios, checking the safe area, assigning an input, and changing text in a UMD.

Users can also instantly change layout configurations, and dynamically zoom one source larger for quality control, or audio monitoring of an on-screen source.

The Kaleido-RCP2 remote panel exemplifies this simplicity, and provides easy multiroom, multioperator control over Ethernet, with local  connections for a mouse and keyboard.
