Abstract
Audio data transmission and reception methods and an electronic apparatus using the same are provided. The audio data transmission and reception methods send audio data by one bit at the rising edge and at the falling edge of a bit clock, and send audio data over a null interval carrying no data. Hence, 5.1 channel audio data can be transmitted and received using an I2S transmission scheme.
Claims25
An audio data transmission method comprising:
- transmitting a first clock signal;
- transmitting a second clock signal, the second clock signal having a frequency which is higher than a frequency of the first clock signal, while transmitting the first clock signal;
- and
- transmitting a plurality of bits of audio data over one period of the second clock signal.
1 more element
An audio data reception method comprising:
- receiving a first clock signal;
- receiving a second clock signal, the second clock signal having a frequency which is higher than a frequency of the first clock signal, while receiving the first clock signal;
- and
- receiving a plurality of bits of audio data over one period of the second clock signal.
1 more element
An electronic device comprising:
- a transmitter which transmits a plurality of bits of audio data over one period of a second clock signal, the second clock signal having a frequency which is higher than a frequency of a first clock signal;
- and
- a receiver which is synchronized with the transmitter and which receives the plurality of bits of audio data from the transmitter.
