Extron is now shipping its Quantum Expansion IN and Quantum Expansion OUT cards, which simplify the design, integration, and operation of large videowalls.

The cards link up to five Quantum Ultra frames together, extending the high-speed HyperLane bus between processors. Once configured, the processors operate as a single system with a common, shared bus. This makes each input source available to all video outputs.

Quantum Ultra outputs are genlocked across all frames, maintaining image synchronisation and eliminating video tearing. Integrating Quantum Ultra processors configured with Quantum Expansion cards provide flexible system design for large videowalls without the need for front-end switching or distribution amplifiers.

Quantum Ultra can accommodate a mixture of display devices with varying resolutions. Features such as output overlap, bezel compensation, output rotation, and custom output resolutions provide compatibility with current and next-generation display devices. The future-ready Extron HyperLane bus delivers real-time performance unattainable by other videowall processors. It has a maximum throughput of 400 Gbps, sufficient to simultaneously carry more 4K/60 sources with 4:4:4 chroma sampling. It also possesses the bandwidth required to support evolving signal formats, such as HDR, greater color depth, and expanded color gamut.

Sources can be windowed and positioned anywhere on the video display. Static image files such as logos and maps can be stored locally on the Quantum Ultra and displayed with full keying and alpha channel support. Internally generated clocks can be presented in a variety of time formats and in multiple time zones. The integrated VNC client can decode multiple simultaneous VNC server streams for presentation on the videowall. Also, custom color borders can be applied to any window, with support for rounded corners, drop shadows, flashing, and transparency.

Extron vice president of worldwide sales and marketing Casey Hall says they are enthusiastic about being able to support extremely large videowalls without sacrificing any of their performance or capabilities.

“Quantum Ultra processors configured with Quantum Expansion cards form a cohesive single system that delivers powerful processing features and robust, secure operation for videowalls with up to 168 sources and screens.”
