Abstract

Los sistemas y técnicas para procesar datos de video incluyen una tabla de predictores de video de movimiento basado en historial (HMVP) con dos o más candidatos HMVP, en donde una primera entrada de la tabla HMVP asociada con un primer valor de índice incluye un primer candidato HMVP y una segunda entrada de la tabla HMVP asociada con un segundo valor de índice incluye un segundo candidato HMVP, el primer valor de índice es más bajo que el segundo valor de índice. Para una lista de candidatos de predicción del vector de movimiento (AMVP), uno o más candidatos HMVP de la tabla HMVP se seleccionan en un orden inverso, donde el segundo candidato HMVP se selecciona antes que el primer candidato HMVP de acuerdo con el orden inverso. El uno o más candidatos HMVP seleccionados se agregan a la lista de candidatos AMVP. La lista de candidatos AMVP se puede utilizar para llevar a cabo el AMVP para el uno o más bloques de datos de video.
