Abstract:
A coding compression method for encoding a video image signal with a variable bit rate, comprising:performing coding to said video image signal for each predetermined coding unit in accordance with a predetermined first coding parameter, which coding is completed within said coding unit, thereby generating a first coded stream; creating a second coding parameter of said video image signal for each said predetermined coding unit while creating said first coded stream; indicating a partial section of said first coded stream, said partial section comprising said predetermined coding units; editing said second coding parameters corresponding to said partial section of said first coded stream; performing coding to said video image signal of said partial section of said first coded stream in accordance with said edited second coding parameters thereby to produce a second coded stream; and replacing a partial section of said first coded stream with at least a partial section of said second coded stream, said partial section of said second coded stream corresponding to said partial section of said first coded stream.
