    Abstract: PROBLEM TO BE SOLVED: To accurately specify a band having a large error among all the bands by using a small calculation amount. SOLUTION: A first position identification unit 201 uses a first layer error conversion coefficient including an error of a decoding signal for an input signal to search for a band having a large error in a relatively wide bandwidth in all the bands of the input signal and generates first position information indicating the identified band. A second position identification unit 202 searches for a target frequency band having a large error in a relatively narrow bandwidth in the band identified by the first position identification unit 201 and generates second position information indicating the identified target frequency band. The encoding unit 203 encodes a first layer decoding error conversion coefficient contained in the target frequency band and generates encoding information. The first position information, the second position information and the encoding information are transmitted to a communication partner. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To simultaneously transmit various additional information such as audio information, character information, and image information while suppressing the communication cost and the line use ratio without increasing the calculation cost in the decoding. SOLUTION: An encoded information analysis unit 602 outputs transmission mode information and an additional information flag to an additional processing unit 603 and outputs an information source code of each layer to the additional processing unit 603 according to the transmission mode information. According to the combination of the transmission mode information and the additional mode information, the additional processing unit 603 performs additional processing of the additional information for the information source code of each layer. An encoded information integration unit 604 integrates the transmission mode information, the additional mode information, the additional information flag and various information source codes input from the additional processing unit 603.
