Patent ID: 8793722

Claim:
A process for secure distribution of video sequences codes in accordance with a nominal stream format comprising visual data and data for configuration of decoding of the video sequences codes that does not represent the visual data, the process comprising: receiving a first video stream having a nominal video format; analyzing and storing data related to the configuration of the decoding of the first video stream, the stored data representing data necessary for the configuration of the decoding; modifying the first video stream to replace intercalate the stored data with false decoding data of the same nature as the stored data while maintaining the nominal video format to obtain a modified second video stream, the false decoding data being a modification of the data for the configuration of the decoding, wherein the modified second video stream is incorrect from a visual standpoint of a human but correct from an MPEG format standpoint; creating a third stream with the stored data, wherein the third stream represents a portion of the data of the first video stream; transmitting the modified second video stream and the third stream in separate streams to a receiving device; and aggregating in the receiving device the second modified video stream and the third stream by replacing the stored data contained in the third stream into the second modified video stream to obtain the first video stream.
