摘要
The invention relates to a method for digitally encoding a source multimedia content in a video stream, the method comprising: - generating (S1) a set of versions (Vi) of said multimedia content, each being characterized by a resolution and comprising a succession images, - determine (S2, S3), for each image, a temporal characteristic and a spatial characteristic, - calculate (S4), for each image, a range of video bitrate values by applying a predetermined function (F ) the temporal characteristic, the spatial characteristic and a theoretical value relating to a target encoding quality, - calculate (S5), for each version and for each theoretical encoding quality value, an overall video bit rate as a function of the video bit rates associated with said theoretical value to obtain, for each version, a set of overall video bit rate-theoretical quality pairs.
