System and method for transmitting multimedia information streams, for instance for remote teaching
First Claim
1. System (1) for transmitting a multimedia stream between at least one transmitter (3) and at least one receiver (5), characterised in that said multimedia stream comprise at least an audio/video stream with at least an auxiliary information stream associated thereto, said audio/video and auxiliary streams comprising respective objects, and in that, in said multimedia stream, to at least some of said objects is associated a respective description and space-time characterisation, so that said at least one receiver (5) is able to interact with said objects, modifying their space-time position in said multimedia stream, independently from said at least one transmitter (3).

Abstract
A system for accomplishing the transmission of a multimedia stream between at least a transmitter (3) and at least a receiver (5). The multimedia stream comprises an audio/video stream with at least an information stream associated thereto. To at least some of the objects included in the multimedia stream is associated a respective description and space-type characterisation, so that each receiver (5) is able to interact with the aforesaid objects changing their space-time position relative to the other stream independently from the transmitter (3) and from the other receivers. Preferential application to remote teaching techniques.
