PROBLEM TO BE SOLVED: To reduce costs for manufacturing by miniaturizing a sound receiver. SOLUTION: A sampling point is detected by sampling an input AES (audio engineering society) signal with a fast clock. Based on the detected sampling point, a shift register part 11 takes the AES signal inside, and a preamble detection part 13 detects a preamble part in a header area of the AES signal. Then, an AES decoding part 14 decodes the bi-phase modulation of the AES signal based on the detected preamble part to sample sound data. COPYRIGHT: (C)2007,JPO&INPIT
