SuperVision is a content distribution system (later renamed "Digital Signage" by the IT Industry) developed for Marketing Force Japan through the 3rd party company Right Weight Process (later renamed Invio Inc., though both companies are now defunct) of which I was the project lead and lead developer.
The intended audience was (and still is) the Miyagi Seikyo chain of Supermarkets located throughout the Miyagi region of Japan, with the first installments in Sendai, all of which are still in use today.
An admin terminal is used to gather video and media from various 3rd party sources which are then assembled into a daily "playlist" for each different "section" of the supermarket. (Meat, Dairy, Snacks, Vegetables, etc.) These playlists can be scheduled for any specific day or in a regular weekly/daily schedule. The contents are then distributed to all branch locations through their store manager terminal each morning via bittorrent technology (so the main server does not have to bear the full load of 90+ stores requesting large volumes of data) at which point the different monitors in the store (meat, vegetables, ready-made produce) can play their daily contents in a loop.
One unique feature is the inclusion of a special on-floor terminal that allows for contents to be "pushed" to all monitors, such as an in-store timely sale or the completion of in-house produce or baked goods.
In an independent case study of the system, sales were found to be up to 5 times greater for advertised produce in-store than at locations that did not make use of the SuperVision system. The system has been a large success.
