Abstract

RESUMEN Un dispositivo de ejemplo para codificar datos de video que incluye una memoria configurada para almacenar datos de video; y una o más unidades de procesamiento implementadas en circuitos y configuradas para: almacenar información de movimiento para una primera línea de unidad de árbol de codificación (CTU) de una imagen en un primer búfer de predicción de vector de movimiento histórico (MVP) de la memoria; restablecer un segundo búfer MVP histórico de la memoria; y después de restablecer el segundo búfer MVP histórico, almacenar información de movimiento para una segunda línea CTU de la imagen en el segundo búfer MVP histórico, siendo la segunda línea CTU diferente de la primera línea CTU. Los subprocesos separados de un proceso de codificación de video ejecutado por uno o más procesadores pueden procesar las respectivas líneas CTU, en algunos ejemplos.
