With sample configuration of word length of specification, the transmission mode for digital audio signal transmission which at the same time is generated at sampling speed of specification

摘要

(57) Abstract The digital audio signal is transmitted, the digital transmission mode which has possessed the transmitter (11) and the receiver (13) which at the same time are received is disclosed. The digital audio signal with sample configuration of word length (WL) of certain ru specification, furthermore is generated at sampling speed of certain ru specification. The transmitter, as the digital audio signal is received, 1st information word (IW₁) and has the entry terminal (25,30,32) which receives with the 2nd information word (IW_{2 which it} is related to the word length of aforementioned specification) which it is related to the sampling speed of aforementioned specification. Although through the transmission medium (TRM, 12), it transmits with the digital audio signal and 1st and 2nd information word, there is a format conversion unit (28) which is synthesized in the ideal serial data stream. It makes the word length (WL) of the sample of the digital audio signal being displayed with the number of bits equal in n, n makes the integer which is larger than as many as 0 here, makes sampling speed equal in 2^p F, _s designates p as the integer which is larger than as many as 0 here, makes F _s equal in one cycle numerical value which is fetched from the group which at least consists of two cycle numerical values the group of aforementioned cycle numerical value that tries includes the cycle numerical value of 44.1kHz and 48kHz. The receiver has the sampling speed converter which converts the sampling speed of the signal which this receives.
