Digital audiovisual flow distribution process, involves proceeding on flow before its transmission to recipient equipment by separation of flow into two parts and transmitting complementary information and flow

摘要

The process involves proceeding on a digital audiovisual flow (1) before its transmission to recipient equipment by separation of the flow into two parts to generate a principal modified flow. The flow (1) is transmitted via separated channels during a modified flow distribution phase. Complementary information (3) is transmitted to the equipment by passing via a local server connected with the equipment via an access point. An independent claim is also included for a system for the secured distribution of digital audiovisual flow.
