SIGNALLING ID OF SUB-IMAGES WHEN ENCODING VIDEO BASED ON SUB-IMAGES Russian patent published in 2024 - IPC H04N19/30 

FIELD: physics.

SUBSTANCE: invention relates to encoding and decoding images. Such a result is ensured by receiving a bit stream including SPS, PPS and sub-images associated with sub-image ID matching. Determination is made with respect to whether the SPS flag has a first or a second value. SPS flag having a first value indicates that sub-image ID matching is signalled in SPS, and the second value indicates that the sub-image ID matching is signalled in the PPS. Sub-image ID comparison is obtained from the SPS when the SPS flag has a first value and from the PPS when the SPS flag has a second value or the PPS flag has a first value.

EFFECT: high efficiency of encoding and decoding images.
