Abstract

um aparelho para decodificar dados de vídeo é configurado para determinar, com base em um formato de amostragem croma para os dados de vídeo, que uma transformada de cor adaptativa está habilitada para um ou mais blocos dos dados de vídeo; determinar um parâmetro de quantificação para o bloco ou blocos com base na determinação de que a transformada de cor adaptativa está habilitada; e desquantificar coeficientes de transformada com base no parâmetro de quantificação determinado. um aparelho para decodificar dados de vídeo é configurado para determinar, para um ou mais blocos dos dados de vídeo, que a transformada de cor adaptativa está habilitada. receber, em um conjunto de parâmetros de imagem, um ou mais valores de deslocamento em resposta à habilitação da transformada de cor adaptativa; determinar um parâmetro de quantificação para um primeiro componente colorido de um primeiro espaço colorido com base no primeiro do valor ou valores de deslocamento; e desquantificar os coeficientes de transformada com base no parâmetro de quantificação.
