    • According to the embodiment of the present invention, a method for decoding a video image comprises: a step for receiving a fraction of the information for original image data, a step for generating plural kinds of side information by predicting the original image data, a step for generating the final side information by applying a fraction of the information to each kind of side information, and a step for decoding the original image data using a fraction of the information and the final side information. When the original image data is decoded in a decoder, the data with the minimum errors compared with the original image data can be selected from the plural kinds of information generated by the decoder so that the decoded image quality may be improved. The compression performance for distributed video coding can be improved as a result of excluding the transmission of additional information for confirming the accuracy of the data that decoded the original image.
    • 根据本发明的实施例,一种用于解码视频图像的方法包括:用于接收原始图像数据的信息的一部分的步骤,用于通过预测原始图像数据来生成多种辅助信息的步骤, 用于通过将一部分信息应用于每种辅助信息来生成最终辅助信息,以及用于使用一部分信息和最终辅助信息来解码原始图像数据的步骤。 当在解码器中对原始图像数据进行解码时,可以从解码器生成的多种信息中选择与原始图像数据相比具有最小误差的数据,从而可以提高解码图像质量。 由于排除了用于确认解码原始图像的数据的准确性的附加信息的传输,所以可以提高分布式视频编码的压缩性能。
