Abstract
Se describen técnicas para las operaciones de la lista de candidatos basada en el historial en la codificación de video para determinar información de movimiento para un bloque actual. En un ejemplo, un dispositivo para decodificar datos de video incluye una memoria configurada para almacenar una lista de candidatos basada en el historial y un decodificador de video. El decodificador de video está configurado para construir la lista de candidatos basada en el historial almacenando, en la memoria, la información de movimiento de los bloques reconstruidos en la lista de candidatos basada en el historial como candidatos de la lista de candidatos basada en el historial, identificar un subconjunto de candidatos de la lista de candidatos basada en el historial, generar una lista de candidatos basada en el subconjunto identificado de candidatos de la lista de candidatos basada en el historial y reconstruir un bloque actual basado en la lista de candidatos generada.
