Abstract

sinalização em nível de bloco de desvios de parâmetro de quantização de croma na codificação de vídeo. são descritos exemplos de sinalização em nível de bloco de desvios de parâmetro de quantização. tal sinalização em nível de bloco de desvios de parâmetro de quantização fornece flexibilidade em nível de bloco para determinar um parâmetro de quantização de croma (qp) mais preciso para um bloco de croma. com a sinalização de desvio de parâmetro de quantização em nível de bloco descrita nesta revelação, há mais flexibilidade na definição do qp de croma, resultando na determinação mais precisa do qp de croma em uma base de bloco de croma por bloco de croma.
