Abstract
A request message containing a first description defining a portion to be extracted from multimedia data and a second description defining a scheme for extracting the portion is received from a data reception apparatus. The portion defined by the first description is extracted as partial data from the multimedia data. A coefficient corresponding to the scheme defined by the second description is acquired. Whether a value corresponding to the acquired coefficient is larger than a threshold is determined. If the value is larger than the threshold, the partial data is compressed, and compressed data obtained by the compression is transmitted to the data reception apparatus. If the value is equal to or smaller than the threshold, the partial data is transmitted to the data reception apparatus.
