combination with horizontal LED stripes, comprised 274 separate video cubes. In the largest studio (studio 8), the total playback resolution is the equivalent to 12 x HD next to each other. The configuration relies on
playback power provided by a Picturall Octo media server, which provides a HD DVI on each output at a resolution of 1920 x 1080. However, to multiply this, a Datapath x4 is connected to each of the server’s outputs, providing a custom HD resolution of 3840x1080 at 50Hz. “The x4 takes out the first and second HD files and the server ‘sees’ these outputs as independent screens,” explains Goubert. “In fact, the dual link DVI input on the Datapath x4 is critical to this application as many competitor products only offer a standard single link.”
Each output of the Datapath x4 can represent an arbitrary crop region of the original input image. The output resolution and frame rate does not need to be related to that of the input, as the Datapath x4 will optionally upscale and frame rate convert each cropped region independently. In studio 8, the media
server has an input slot to accommodate four HDSDI feeds from the studio matrix. From here, six outputs are connected to six Datapath x4 display wall controllers. Each group of 6x5 cubes is served by one output of one Datapath x4. These regions can overlap to
allow any output to replicate another, or they can be configured to support any creative splice of the source material. With each x4 providing 2 x HD, this gives a video wall capable of media file playback at 12 x HD. Custom software enables the crew to playback all the media as a cue list.
Although installed in July, a full test set-up was first constructed at BlinkBlink where stress tests were performed — testing with very high resolution media files and data rates to ensure that the overall system could keep up. “Television studios are
typically complex applications, but the efficiency of our business operation in combination with a down to earth attitude and cost effective proposal clearly made for a winning formula in this case,” he says. “In fact, there was a
