FIELD: video data decoding.
SUBSTANCE: invention relates to methods for decoding video data in a video decoder. The method receives a first High-Level Syntax Element (HLS) indicating whether Set Selection (SS) is enabled or disabled for an intra-coding block, wherein Transform Type information indicating the type of transformation is obtained at Explicit SS; receiving a second HLS element indicating whether explicit SS is enabled or disabled for an outer coding block, wherein the first and second HLS elements control the same set of coding blocks that include said intra coding block and said outer coding block, and enabling implicit SS for an intra-coded block, when the first HLS element indicates that explicit SS is disabled for the intra-block, regardless of whether the second HLS element indicates that explicit SS is enabled or disabled for the outer-encoding block, wherein the conversion type information is not signaled by the implicit SS.
EFFECT: reducing the load on the processor by optimizing data processing for signaling the type of conversion.
