ABSTRACT:
A scalable encoding method accurately performs the decimation of a low-resolution frame from a high-resolution frame by compensating for the energy of the low-resolution image in consideration of the rate of the total energy of high-resolution to the partial energy of a corresponding block to be decimated, alleviating the drift effect and enabling good video recovery.
