FIELD: information technology.
SUBSTANCE: invention relates to encoding/decoding video. Method of forming a scalable data stream includes: generating two or more scalability layers of a scalable data stream; inserting a first scalability layer identifier value in a first elementary unit including data from a first scalability layer; causing first scalability layer to be signalled with said first and second set of syntax elements in a first parameter set elementary unit; inserting first scalability layer identifier value in first parameter set elementary unit; inserting a second scalability layer identifier value in a second elementary unit including data from a second scalability layer; causing second scalability layer to be signalled with said first and second set of syntax elements in a second parameter set elementary unit; inserting second scalability layer identifier value in second parameter set elementary unit.
EFFECT: technical result is indication multi-layer parameters for bit sub-streams in a video sequence.
