Video distribution by DOOH vendors is typically done by:
- "Sneakernet", a weekly round of USB key updates sent out to screens
- IPTV which can fail if there is a loss of network
There is a need for efficient fault tolerant online distribution.
The Web has benefits of caching facilities, video playback, all based on open standards and therefore avoid proprietary lock in.
Once a manifest of videos (a schedule) is cached, a network failure should go unnoticed.
Furthermore if power loss occurs and the Neon display is rebooted, the applicationCache should persist. The application cache should also facilitate faster load times.
