<P>PROBLEM TO BE SOLVED: To solve the problem in which: when video encoding is performed, processing such as reduction of the screen size of video prior to the video encoding and enlargement of the screen size of the video after video decoding is performed in some cases; it is necessary to use a low-pass filter having a filter characteristic for removing an aliasing noise part in an application not permitting aliasing noise; but, input video encoding information does not have information on aliasing noise, so that it cannot be determined what type of filter processing is to be performed. <P>SOLUTION: The presence/absence of aliasing noise and the maximum value and the minimum value of a contained band are contained in video information and transmitted. According to the present invention, for example, use of information on aliasing noise transmitted after video decoding enables an influence of aliasing noise to be estimated and the aliasing noise to be removed using a low-pass filter as necessary. <P>COPYRIGHT: (C)2012,JPO&INPIT |
