The V-40HD Live Video Switcher is designed for any live event or installation that requires the freedom to connect a variety of sources - whether digital or analogue, computer or video format - and is suitable for configurations using HDMI cameras as well as computers. As a true multi-format video switcher, there is no need to match the input sources to the output resolution as each input has its own broadcast quality scaler - scaling each source as required to fit the chosen output resolution.
The Roland V-40HD features 12 inputs on four channels plus one (background), and two output buses with independent scalers on the inputs. The inputs allow the user to connect HDMI/DVI, RGB, component and composite sources to the switcher. The V-40HD will support input/output resolutions up to 1080/60p or 1920x1200 and is HDCP compliant which allows you to mix copy-protected game and Blu-ray content with other computer and camera sources (digital outputs only).
The input source multi-viewer on the V-40HD output provides a convenient monitoring solution when connected to an HDMI monitor. The V-40HD also includes an audio input bus with volume and delay settings allowing you to embed audio into the HDMI output signal, which is especially useful for streaming and recording applications.
The Multi-Zoom feature of the V-40HD can be enabled where one input source is shared internally with up to three more inputs (daisy chaining). The scaler for each input can zoom and pan into any position in the video image giving the appearance that additional cameras are connected and creating a virtual multi-camera environment. Additional effects include a downstream keyer (DSK), Picture-in-Picture and multiple transitions.
