FIELD: information technology.
SUBSTANCE: droppable low level of a video signal is adapted, where applications may not transmit unused inter-level prediction data for all levels lower than the working point of receivers. Indicator flags are used to avoid transfer of syntax elements which must be set into fixed values. Algorithms for populating or restricting additional coding are also used during coding.
EFFECT: higher coding efficiency and decoding accuracy during video signal scalable coding.
