Abstract RU 2780809 C1

FIELD: video data processing.

SUBSTANCE: group of inventions relates to video encoding/decoding and generally describes the technology of new-generation video encoding; in particular, generally relates to methods and apparatus associated with processing an image header. Proposed is a method for video data decoding, wherein the method is implemented by at least one processor. The method includes a stage of indicating, using the syntax element of the image header, for all slices included in the corresponding encoded image, whether said slices are type B, P, and/or I slices, wherein the syntax element is encoded using an unsigned integer. The video data is decoded based on the types of slices indicated by means of the syntax element.

EFFECT: reduced amount of signalling service data when indicating the slice type.
