Logiciel de mur vidéo

Votre mur vidéo typique nécessitait auparavant une expertise particulière, du matériel coûteux et des logiciels complexes. C'était une affaire très compliquée qui nécessiterait de nombreuses heures de planification et de recherche. Bien que quelques installations puissent encore nécessiter des solutions propriétaires ou coûteuses, de nombreux résultats professionnels peuvent être obtenus à l'aide d'un logiciel de mur vidéo d'affichage dynamique disponible dans le commerce.

Today, excellent results can be achieved using a multi-display capable PC and compatible commercial gestion de contenu (CMS).  While Android and other alternate types of devices are becoming more common, not many can support multiple displays like PCs.

Choisir le bon logiciel CMS pour le travail

Il est sûr de dire la plupart des 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.

Affichage des données sur les écrans de votre mur vidéo

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.

Contrôler le canevas multi-écrans

De nombreux logiciel d'affichage dynamique 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 logiciel d'affichage dynamique 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.

Exemples d'applications de mur vidéo

Panneaux de menus de restaurants: Denombreux restaurants utilisent un logiciel d'affichage dynamique basé sur 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.

Murs vidéo 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 murs vidéos 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.

Murs vidéo transparents: 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.

Signalisation LED extérieure: 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.

Avantages d'un mur vidéo basé sur un logiciel

Les murs de vidéo that are built around technologies d'affichage dynamique represent significant advantages over hardware-based video wall installations.

  • Coûts réduits : Dedicated, hardware based video wall controllers tend to be much more expensive than affichage dynamique based systems that use regular PCs with multi-output video cards.
  • Facilité de configuration et d'utilisation : Les logiciels d'affichage dynamique traditionnels peuvent être relativement faciles à utiliser par rapport aux interfaces propriétaires utilisées pour les systèmes basés sur le matériel. Les PC sont également plus faciles à configurer et utilisent des composants standards (mémoire RAM, disques durs, etc.). Les PC ne nécessitent pas de personnel spécialement formé.
  • Plus de flexibilité : Les contrôleurs matériels sont des appareils à usage unique, ils ne peuvent donc être utilisés que pour cet usage spécifique. Les PC peuvent être reconfigurés, mis à niveau et redéployés très facilement.
  • Facilité d'entretien: Les composants PC sont faciles à trouver et moins chers à l'achat. Ils peuvent être réparés sur le terrain où la plupart des contrôleurs matériels doivent être envoyés à un magasin spécialisé pour les réparations.

Hardware considerations

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.

En attendant, il y a plein de solutions pour chaque projet et chaque budget.
