    Abstract: PURPOSE: A high speed encoding method is provided to determine a motion prediction direction and a reference picture at high speed and to reduce the complexity of an image encoding device. CONSTITUTION: An image encoding apparatus defines a test block group by combination of neighbor blocks of an encoding target block(S310). The image encoding apparatus determines a motion prediction direction of the encoding target block based on a motion prediction mode of the block included in the test block group(S320). The image encoding apparatus determines a reference picture of the encoding target block based on a reference picture of the block(S330).

    Abstract: PURPOSE: An entropy decoding and encoding method and apparatus thereof are provided to improve image compression efficiency by deducting the context information from a decoding target symbol. CONSTITUTION: An entropy decoding apparatus deducts context information from a decoding target symbol by using the context information of a target layer or another layer(S910). The entropy decoding apparatus decodes the decoding target symbol by using the deducted context information(S920). The target layer includes the decoding target symbol. The other layer is a layer except for the target layer.
