A control unit defines one or more vectors of transform coefficients for decoding of the enhancement layer blocks, and selects a prediction mode for the enhancement layer blocks based on the vectorized entropy decoding. Each of the vectors comprises one or more of the transform coefficients in a scan order having an end position indicated by a vector control signal. The control unit selects weighted prediction when the vectorized entropy decoding establishes two or more vectors, and selects non-weighted prediction when the defined vectorized entropy coding establishes a single vector. A prediction unit performs predictive decoding based on the prediction mode. An entropy decoding unit performs the vectorized entropy decoding. A scanning unit scans the enhancement layer video blocks from the vectors into two-dimensional blocks of transform coefficients, and separately entropy decodes the vectors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Weighted prediction based on vectorized entropy coding","description":"A receiver receives coded coefficient values of enhancement layer video blocks.
