<p>The invention relates to a method for allocating bit rates to video programs (14 1 , 14 2, ...14 N ) broadcasted as groups of pictures through a transmission channel (19) having a constant transmission rate, each video program (14i) being encoded through at least one encoding parameter depending on a first smoothness measure representative of quality variations between pictures currently and/ previously transmitted within said video program (14i), characterized in that the encoding parameter also depends on:
- A second smoothness measure representative of quality variations between future pictures to be transmitted thereafter in the same video program, and
- At least one quality standard ensuring an encoding quality for any broadcasted video program, transmitted through the channel (19), above a determined absolute and/or relative quality threshold.</p> |
