Abstract:
1. Method for generating an encoded composed video stream, based on a common video stream and at least one input stream of personalized information, said method comprising: generating at least one intermediate stream by mixing said at least one input stream into said common video stream; encoding said at least one intermediate stream for thereby generating at least one encoded intermediate stream; wherein said at least one intermediate stream is generated by adding said at least one input stream in predetermined positions of said common video stream, taking into account a macroblock grouping in slices; said method further including encoding said common video stream using said macroblock grouping, thereby generating an encoded common video stream comprising a sequence of encoded video frames, each encoded video frame comprising a sequence of a predetermined number of slices of encoded macroblocks of said common video stream; whereby said at least one intermediate stream is encoded by using said macroblock grouping, such that said at least one encoded intermediate video stream comprises a sequence of frames of said predetermined number of slices of encoded macroblocks of said at least one intermediate video stream; and said method further including combining and filtering said encoded common video stream and said at least one encoded intermediate stream such that per frame and per slice sequence number only one slice of one stream is selected for forming said encoded composed video stream.
