49 Screens of Video Wall
Al-Hiwar TV, an Arabic language satellite TV channel, decided to apply a video wall consisting of 49 55’’ screens to its new studio in London, the biggest challenge for them was how to achieve good video quality on the video wall when the video source and video wall controller were in the utility room which was 40 meters away from the studio. Nearly all video wall controllers on the market only have standard DVI or HDMI outputs which are only able to offer up to 15 meters distance for 1080p60 video source even with expensive and very thick of 24AWG cables.
Another challenge for them was to use one video wall controller to control more than one video wall individually in that studio, since total 2 video walls were formed with these 49 screens for its main news presentation desk and a secondary meeting & interview table area.
When VMClouds, the system Integrator for this project, came to SEADA for help, we offered our SolarWall video wall controllers with HDBaseT graphic cards and MVWS (Multi Video Walls Support) technology.
The HDBaseT video outputs on SEADA’s SolarWall video wall controller enable the Al-Hiwar TV to locate the controller far away from the video wall screens (up to 100 meters) without losing any quality. It makes the cabling much easier and also saves a lot of cost on just using CAT cable instead of expensive HDMI/DVI cables.
SEADA’s MVWS technology enables users to control up to 4 video walls simultaneously from the same SolarWall controller, which makes the management much easier and saves cost on chassis and capture cards since only one chassis is needed for 4 video walls and capture cards can be shared between video walls. This technology was perfect for Al-Hiwar TV requirement of controlling two video walls with one controller.
