Abstract: Provided are a method for managing a reference picture list, and an apparatus using same. An image decoding method comprises the steps of decoding one picture of second-highest temporal layer pictures in a hierarchical picture configuration; and decoding top temporal layer pictures which precede and follow the second-highest temporal layer pictures with respect to a picture order count (POC) in a POC sequence, respectively. Therefore, available reference pictures remain in a decoded picture buffer (DPB), thereby improving image-encoding efficiency.

Abstract: La presente invención se refiere a un método de intra-predicción, y a un codificador y decodificador que lo utilizan. El método de intra-predicción de acuerdo con una modalidad de la presente invención consiste en los pasos de: derivar un modo de predicción de un bloque actual, y generar un bloque de predicción con respecto al bloque actual con base en el modo de predicción del bloque actual. Cuando el modo de predicción del bloque actual es un modo de predicción intra-angular, los valores de las muestras limítrofes de entre las muestras limítrofes izquierdas y las muestras limítrofes superiores del bloque de predicción, las cuales no. Están posicionadas en: una dirección de predicción del modo de predicción. intra-angular, se derivan con base en las muestras de referencia posicionadas en la dirección de predicción del modo de predicción intra-angular y don base en las muestras de referencia adyacentes.

Abstract: The method for deriving a temporal motion vector predictor according to the present invention comprises the steps of: selecting a reference picture for a current block; deciding a predictor block corresponding to a predetermined storage unit block, as a reference prediction unit for the current block, in the reference picture; and deriving the temporal motion vector predictor from motion information of the decided reference prediction unit. The present invention enhances image compression efficiency.
