PowerWall

As large video walls are widely used in the broadcast environment, there is a need for a cost-effective solution for delivering compelling graphical content at very high resolutions.
PowerWall is a turnkey system for video walls, based on Orad’s HDVG4 platform that provides up to 16k resolution output from a single box. .
Whether the productions are news, entertainment, sports or elections, Orad’s PowerWall can be integrated into the production workflow.

Unprecedented resolution and capabilities
 

As the successor to the HDVG, the HDVG4 introduces unrivalled capabilities to the video wall environment. This single unit outputs 8 genlocked 3G or 16 HD SDI signals that can be tiled across the video wall according to the size and shape required. Multiple output options allow the HDVG4 to closely match the resolution and aspect ratio of the video wall. The resolution can range from 3840x1080 in the 2x1 setup, 7680x2160 in the 4x2 setup and a staggering 15360x2160 in the 8x2 arrangement, all from a single HDVG4.

This high resolution provides studios with the ability to zoom in on the screen without the graphic content becoming pixelated.

The HDVG4 can accept up to 12 HD or 12 SD live video insertions, as well as video clips in most industry accepted formats, which can mapped to different graphical elements on the video wall. All of these video elements become an integral part of the templates and are not overlaid as ‘picture-in-picture’ objects.

By running from a single box, all on-screen elements (tickers, videos, animated items, etc), will remain synchronized across the whole of the video wall, with no tearing visible on any sections of the output.

Convenient Control 

The PowerWall Configurator allows users to easily adjust the properties of the video signal without having access to the engineering controls on the video wall.

Users can adjust the size, position, edges and colour balance of the whole wall or individual signals from the control PC.

No compromises on design 

PowerWall’s graphics content is created using 3Designer, Orad’s award winning graphic creation package. 3Designer is used to create templates for any type of broadcast, including news, special election broadcasts, sports casting, weather segments, business reports and more.

While working in 3Designer, the entire video wall is treated as a single scene, so full screen graphics will be created without tearing where video wall tiles meet. Guides and markers can be placed on the template enabling the display and align elements to be subdivided precisely.

The templates contain both graphics and animations; different scene elements can be dynamically updated and controlled during production.
Each layer can also be mapped as a texture on the surface of another object, opening the way for stunning new types of animations and effects that are normally only possible in post-production.

3Designer also offers state-of-the-art 3D and decorated text capabilities. A unique algorithm was developed to ensure the maximum text quality at any given text size, thus avoiding text blurriness or pixelization. In addition, 3Designer fully supports Unicode and multiple regional language environments, multi-line and multi-style texts, shrink-to-fit, alignment and kerning adjustment.

In order to enhance the level of photorealism, 3Designer is also fully equipped with texture and layer blending modes, and shaders such as bump mapping, displacement mapping and other video effects.
3Designer also provides an API which allows programmers to write their own shaders and implement them using 3Designer.

Seamless workflow integration
 

Taking graphics to air is straightforward. The content can be controlled by Orad’s TD Control, 3DPlay or Maestro applications, all of which are already in use extensively in the broadcast environment.

TD Control allows the Technical Director (or vision mixer operator) to call up different graphical templates and video boxes from their station. TD Control is based on a touch screen user interface which gives the TD the option to control the software from TD Control’s user interface or directly from the vision mixer.
 

3DPlay and Maestro can be seamlessly integrated with existing newsroom and automation systems giving a flexible production environment, allowing journalists, artists and producers to work freely with the new display possibilities.

Templates controlled by Maestro or 3DPlay can be pumped with external data from databases such as Oracle, SQL, ODBC, Excel, XML, and more.

Each scene can encapsulate an unlimited number of data connections. The connection to the database is done using drag and drop methods and no scripting knowledge is required. A set of query tools allows operators to sort and manipulate the data automatically, streamlining and enhancing the production workflow.

If Orad is already part of the production workflow, then the adoption of a video wall only requires the addition of a HDVG4 system. Existing graphic content can be used in the video wall with only minimal repurposing, and control can be carried out from the same 3DPlay or Maestro production applications, or if integration with the mixing desk is preferred, TD Control.
