Roland bolsters video switcher line up

Roland Systems Group has bolstered its line of multi-format video mixers with the Roland V-800HD Multi-Format Live Video Switcher.

It features high definition picture quality and eight multi format channels with independent scalers as well as a variety of output formats including a built-in multi-viewer. It is suitable for live performances and events, corporate productions and web streaming.

The unit does not require input sources to be the same format or to match the video output format. Built-in scalers on all inputs can individually scale, stretch, crop and zoom any video source to the optimal resolution. This offers full support for video cameras and computer outputs at a full range of resolutions.

It supports 1080p video signals at bit rates up to 3Gbps.

The V-800HD is HDCP (High Bandwidth Digital Content Protection) compatible and also features a built-in multi-viewer output. The eight mixing channels provide connectivity to 4 x 3G/HD/SD-SDI or composite and 4 x DVI-A/DVI-D/HDMI, RGB or component formats – as well as an additional two channels for still images assignable via USB memory stick or frame grab.

A 15 pin D-Sub type connector accommodates SD/HD component as well as computer input via analogue RGB.

The unit boasts upgraded 4:4:4/10-bitinternal signal processing, and a newly developed key-compositing engine that allows adjustment of phase range, amount of chroma, and other parameters based on HSV colour space. This feature enables high quality chroma key compositing even when using 1080p video sources.

Assignable video cross-points allow the reordering of channel buttons. A dedicated composite output provides an always available down-converted SD signal that is ready to use for archiving to a DVD recorder or to an encoder for streaming.

The Multi-Zoom feature can be enabled when one video input is shared internally with up to three more inputs – essentially daisy-chaining it. The scaler for each input can zoom into any position in the video image giving the appearance that additional cameras are connected – creating a virtual multi-camera environment. Additional effects include a down stream keyer (DSK), a composite keyer, Picture-in-Picture and multiple transitions.

The V-800HD can be used in a system design and creative production environment as well as for live or fixed installation applications, including those with LED wall sizing challenges. With video output resolutions up to 1080/60p, 4:4:4/10-bit processing, and support for 3G SDI input resolutions; the V-800HD achieves video production for live event, broadcast, corporate, educational, and house of worship applications.
