Abstract

um codificador de vídeo decodifica uma unidade de codificação (cu) de dado de vídeo. em decodificação do dado de vídeo, o codificador de vídeo determina que a cu foi codificada usando a conversão de cor espaço. o codificador de vídeo determina o parâmetro de quantização inicial (qp), determina o qp final que é igual a uma soma do qp inicial e um deslocamento de qp, e quantiza inversamente, com base no qp final, um bloco de coeficiente, então reconstrói a cu com base nos blocos de coeficiente quantizados inversos.
