Transmission apparatus, transmission method, reception apparatus, and reception method

A transmission method, comprising the steps of:

• acquiring multichannel audio data of a predetermined number of channels,
• the multichannel audio data having a sampling frequency corresponding to the predetermined number of channels;
• sequentially transmitting audio data of the respective channels configuring the multichannel audio data to a reception side via a predetermined transmission channel for each unit audio data;
• and
• adding information indicating the sampling frequency to the audio data transmitted in the data transmission step.

A reception apparatus, comprising:

• a data reception unit that sequentially receives audio data of respective channels configuring multichannel audio data of a predetermined number of channels from a transmission side via a predetermined transmission channel for each unit audio data;
• the multichannel audio data having a sampling frequency corresponding to the predetermined number of channels,
• the audio data received by the data reception unit having information indicating the sampling frequency added thereto;
• and
• a processing unit that recognizes the predetermined number of channels based on the information indicating the sampling frequency and processes the audio data received by the data reception unit.

A reception method, comprising the steps of:

• sequentially receiving, by a data reception unit, audio data of respective channels configuring multichannel audio data of a predetermined number of channels from a transmission side via a predetermined transmission channel for each unit audio data;
• the multichannel audio data having a sampling frequency corresponding to the predetermined number of channels,
• the audio data received in the data reception step having information indicating the sampling frequency added thereto;
• and
• recognizing the predetermined number of channels based on the information indicating the sampling frequency and processing the audio data received in the data reception step.

A transmission apparatus, comprising:

• a data acquisition unit that acquires multichannel audio data of a predetermined number of channels;
• and
• a data transmission unit that sequentially transmits audio data of the respective channels to a reception side via a predetermined transmission channel in a state where a preamble is added thereto for each unit audio data,
• a pattern of the preamble added to a head unit audio data out of consecutive unit audio data pieces of the predetermined number of channels being a specific pattern indicating a head position.
