DISTRIBUTED AND SECURED METHOD AND SYSTEM FOR PROTECTING AND DISTRIBUTING AUDIO-VISUAL FLOWS

摘要

The invention relates to a method for securely distributing digital audio-visual flows according to a standard format which is normalised or proprietary. Prior to the transmission to a recipient device, said flows are divided into two parts in order to generate a modified main flow having the original flow format and supplementary digital information for reconstructing the original flow. Said invention is characterised in that the main modified flow is transmitted through separate channels from a distribution server during the distribution and said supplementary information is transmitted to the recipient device from a secured central server through a local server connecting said recipient device to said central server through at least one access point.
