METHOD AND DEVICE FOR GENERATION OF SCALED ENCODED VIDEO-SIGNAL USING A NON-SCALED ENCODED VIDEO SIGNAL Russian patent published in 2007 - IPC H04N7/26 

FIELD: video signals.

SUBSTANCE: method for modifying data in input encoded video signal for generation of output scaled video signal, composed of main video signal and a set of at least one quality increase video signal, where method contains at least one error decoding stage for generation of decoded data signal using input encoded video signal, first stage of repeated encoding for generation of main video signal using intermediate data signal, received by addition of signal with movement compensation and decoded data signal, reconstruction stage for generating main video signal encoding error, movement compensation stage for generation of signal with compensation of movement based on encoding error, second stage of repeated encoding for generation of quality increase video signal on basis of encoding error. Encoding error of main video signal is repeatedly encoded with higher degree of detail in comparison to error which is used for generation of main video signal.

EFFECT: ensured adaptation of bit-rate of encoded video signal being transferred to traffic capacity of communication network.
