Abstract

La presente invención se refiere a un método para determinar una imagen de referencia para inter-predicción, y a un método de inter-predicción de conformidad con la misma. El método para determinar una imagen de referencia incluye: confirmar el tipo de fragmento de un bloque; si el tipo de fragmento es un tipo de fragmento B capaz de realizar predicción unidireccional o predicción bidireccional, determinar la dirección de inter-predicción del bloque como una primera dirección, una segunda dirección, o ambas direcciones; si la dirección de inter-predicción no es la segunda dirección, determinar un índice de referencia para un bloque como un índice de referencia de primera dirección a partir de una lista de imagen de referencia de primera dirección; y, si la dirección de inter-predicción no es la primera dirección, determinar un índice de referencia para el bloque como un índice de segunda dirección a partir de una lista de imagen de referencia de segunda dirección.
