The BBC currently provide a a commentary track for the current edition of Doctor Who. Imagine if these were available for new movies.
A recent patent filing by Apple proposes public very local networks for iPhones and iPod Touches.
The idea is that shops, public buildings and restaurants set up location-specific applications that appear on iPhones when customers wander into the area of their wireless networks. Restaurants could provide custom menus (for those with food intolerances or on restricted diets), museums and art galleries could provide extra information. Shops could provide customer-specific offers.
If this works, why not provide commentary tracks for moviegoers? If you’ve see the film before, yet want to go and see it with friends, you can turn up and download an alternate soundtrack. You are more likely to see the film a second time in a short period of time. The cinemas sell more tickets.
You could even have alternate language soundtracks or an audio description track for the visually impaired. Imagine if the audio playing software on your iPhone could be triggered by a wireless signal to sync with the film when it starts (or even whenever the person arrives to watch the film).
The software could also ask permission to deny incoming texts and telephone calls until the film is over!
