A method for generating an encoded composed video stream (evideofinal), based on a common video stream (video0) and at least one input stream (input1,...,inputi,...,inputn) of personalized information, includes a step of generating at least one intermediate stream (video1,...,videoi,...,videon) by mixing said at least one input stream (input1,...,inputi,...,inputn) into said common video stream (video0) in predetermined positions of said common video stream, taking into account a macroblock grouping in slices, and a step of encoding said at least one intermediate stream (video1,...,videoi,...,videon) thereby generating at least one encoded intermediate stream (evideo1,...,evideoi,...,evideon) by using said macroblock grouping, and a step of encoding said common video stream (video0) using said macroblock grouping, thereby generating an encoded common video stream (evideo 0), said method including a further step of combining and filtering, by a combining means (F), said encoded common video stream (evideo 0) and said at least one encoded intermediate stream (evideo1,...,evideoi,...,evideon) such that per frame and per slice sequence number only one slice of one stream is selected for forming said encoded composed video stream (evideofinal). |
