Software de pared de video
Su pared de video típica solía requerir experiencia especial, hardware costoso y software complejo. Fue un asunto muy complicado que consumiría muchas horas de planificación e investigación. Si bien algunas instalaciones aún pueden requerir soluciones propietarias o costosas, se pueden lograr muchos resultados profesionales utilizando el software de pared de video de señalización digital disponible comercialmente.
Today, excellent results can be achieved using a multi-display capable PC and compatible commercial sistema de gestión de contenidos (CMS). While Android and other alternate types of devices are becoming more common, not many can support multiple displays like PCs.
Elegir el software CMS adecuado para el trabajo
Es seguro decir la mayoría CMS product on the market can manage and display content on single displays. Things get dicey if you start looking for multi-display capability, and even then, few can easily switch from a single piece of content shown across all displays to individual content on each display. Therefore, you should look for professional-grade video wall software that lets you create flexible layouts with the fewest restrictions.
The best products will let you design layouts so content can be assigned to any number of displays, regardless of their orientation, or resolution. You should be able to assign content that spans one or more display, and change layouts easily. Templates should not be difficult to create or update by non-technical users.
Visualización de datos en sus pantallas de pared de video
Your CMS should support data and graphics overlays so it’s easy for you to add news feeds, weather information, sports results, financial / banking information, corporate data, production statistics, and other live data feeds. Your preferred solution should let you position any image, graphic or text element, anywhere within the multi-screen display area with as few restrictions as possible. Transparency layers should also be available on your video wall software of choice. This lets you create professional looking content like news tickers or a clock with the current date floating on top of any media displayed on screen.
Controlar el lienzo multipantalla
Muchos software de señalización digital products that run on the Windows operating system rely on the PCs video drivers to manage which signal is sent to each display. It’s imperative that your video drivers be current, as new features and bug fixes get released regularly by video card manufacturers. Once your hardware has been installed and the PC configured, you must make sure the video drivers can see every connected display. Displays must also show up in the proper order, otherwise you may see parts of the content appear on the wrong display.
Microsoft Windows and video card driver software applications include features that let you check the order in which your displays are organized. If anything looks suspicious, you can swap out video cables or reorganize the displays using the video driver software until you see the results you expected.
In some cases, you may want to mix your displays orientation. Let’s say you install two displays in landscape and two displays in portrait orientation. You will need a video card with four outputs that support mixed orientations. The video drivers will need to be configured to take the dimensions of all the displays into account. Your software de señalización digital must also support this layout, otherwise you won’t be able to show your content properly. All the components must work together to make the content play properly.
Ejemplos de aplicaciones de video wall
Tableros de menú de restaurante: Muchos restaurantes usan Software de señalización digital basado en PC with multi-display video cards to manage a series of displays instead of deploying one media player per screen. Using a single PC, even with a high-end video card can be less expensive than using one player per display. There are also software savings as only one player software license is required for the entire project.
Paredes de video LCD: Video walls come in many configurations. Displays can be arranged in rows with matching orientations (two rows of three, three rows of four, etc.), or in mixed orientations. Displays can be grouped together to create a single viewing surface or spread out individually. The effect will change with the layout. We often find these digital signage paredes de video in high-end retail stores, car dealership showrooms, stadiums, banks and financial institutions, shopping malls and other areas where people want to make an impact.
Paredes de video transparentes: These use similar LCD display technologies but without any backlighting. Transparent displays can be mounted in windows so the viewer can see through the content being shown. You can see these in trade shows, high-end retail and other specialized applications.
Señalización LED exterior: Exterior LED boards are assembled using smaller panels. Most often, flat panels are used to cover very large areas, but you can find these panels in many shapes and sizes. Some are even curved. These products require special video processor cards that can be configured to operate in non-standard screen resolutions.
Ventajas de un videowall basado en software
- Costos reducidos: Dedicated, hardware based video wall controllers tend to be much more expensive than señalización digital based systems that use regular PCs with multi-output video cards.
- Facilidad de configuración y uso: Traditional software de señalización digital can be relatively easy to use compared to the proprietary interfaces used for hardware based systems. PCs are also easier to configure and use standard components (RAM memory, hard drives, etc.). PCs don’t require specially trained personnel.
- Más flexibilidad: Los controladores basados en hardware son dispositivos de un solo propósito, por lo que solo se pueden usar para ese uso específico. Las PC se pueden reconfigurar, actualizar y volver a implementar muy fácilmente.
- Facilidad de mantenimiento: Los componentes de PC son fáciles de obtener y menos costosos de comprar. Se pueden reparar en el campo donde la mayoría de los controladores de hardware deben enviarse a un taller especializado para su reparación.
Dedicated hardware based display controllers have their purpose. They are essential when designing artistic layouts or when you need to mix displays that have different sizes and image aspects. Hardware display controllers are also extremely reliable but their high cost relegates them to very specific applications. They are rarely used for basic video wall applications anymore.
The advantages of using digital signage software and PC hardware are obvious. You can operate your digital signage video walls with hundreds of other displays and interactive kiosks using a single technology. You control individual displays, multiple video walls with different layouts, touch enabled displays and other means of content presentation using a common software product.
As PC hardware and video card technologies further evolve, we anticipate hardware based video controllers will become obsolete. It’s just a matter of time before video card manufacturers bridge the gap.
Mientras tanto, hay muchas soluciones para cada proyecto y cada presupuesto.
