Abstract

An electronic screen shows video that has a barcode wrapping an URL. A user images the barcode with a mobile device and decodes it into a web page with an audio feed corresponding to the video. Or the barcode wraps a phone number which the user's device contacts to get an audio feed. The web page lets the user pick between several audio feeds, where the feeds might be in different languages. Several users get audio feeds for the same screen. An electronic screen controlled by a user with a mobile device shows a barcode. Another user with a mobile device images the barcode and causes the screen to be 2 split screens, where the original user has one and the new user has the other. Each split screen can offer via barcode a separate audio track that can be heard by a user with a cellphone.
