Abstract
Esta solicitud proporciona un método de codificación y aparato, y un método de decodificación y aparato. El método de decodificación incluye: obtener una primera información de una unidad de árbol de codificación CTU en una imagen a ser decodificada a partir de un flujo de bits, donde la primera información se utiliza para indicar un intervalo de valor permitido de una relación de anchura a altura de una CU obtenida al dividir la CTU; obtener una información de división de la CTU a partir del flujo de bits; dividir la CTU en una o más CU con base en la primera información y la información de división, donde una relación de anchura a altura de la una o más CU se encuentra dentro del intervalo de valor indicado por la primera información, y la pluralidad de CU no se traslapan entre sí; y decodificar la una o más CU para obtener un pixel reconstruido de la una o más CU. En esta solicitud, la división de CU en algunas formas se puede excluir con base en el intervalo de valor durante la decodificación, de modo que la información de división usada previamente para indicar las formas de división para las CU se puede guardar en el flujo de bits, reduciendo de esta manera las tasas de bits ocupadas.
