Over the past few years, changes in the modern workplace coupled with falling prices of large format displays have driven higher customer demand when it comes to synchronized playback across multiple screens. Organizations are keen on using video walls to create a more significant presence for their workplace communications. To meet this demand, traditional solutions use a single device with multiple outputs to distribute and synchronize content playback. However, this solution comes with several drawbacks, such as creative and architectural deployments that challenge video wall implementations.
Appspace has developed a new synchronization method to meet the stringent timing requirements for synchronized video, while also overcoming the drawbacks of the traditional solution. Our decentralized solution leverages off-the-shelf devices. This flexibility improves deployment scalability, making it less costly to deploy and maintain in the long run. With these combinations, we open up digital messaging to various unimaginable ideas, key benefits, and opportunities.
For over 15 years, we have offered a solution that utilizes a single high-performance media player with multiple video outputs. While a great solution, there is a physical limit to the total number of video wall displays that can be connected. Customer considerations with this approach range from potentially higher hardware costs, more complex configuration, and additional hardware to achieve larger video wall setups. Learning from these customer pain points, the Appspace App for Devices provides an alternative configuration method using multiple media players.
How it Works
As we have mentioned, this is a multi-player approach where each display of the multi-screen or video wall has a media player connected to it. With this configuration, one of the media players acts as a controller and timekeeper, while other media players act as worker devices. Through the network, worker devices check what content frame they should be showing, and adjust their playback to sync with the controller. The worker also accounts for the network latency of making this call to the controller. When used in video walls, Appspace splits the video channel into tiles, and each device plays the appropriate tile forming a video wall. As there are no limitations on the number of worker devices, the size of the video wall can adapt to the deployment needs by simply adding more devices.
- Appspace has implemented and enhanced three key technologies to overcome the various problems with content synchronization across multiple screens: Distributed clock synchronization
- Video tile mapping
- Deterministic scheduling
Comparing Video Wall Deployment Types
Appspace’s clock synchronization technology is the key to allowing customers to set up multiple screen synchronization for mirrored displays or video walls on a large scale while keeping their operational costs low.
