Patent ID: 7664126

Claim:
An intermittent communication method for data communication apparatus, comprising: a reception step for receiving data transmitted intermittently from a communication partner side and storing the data into a buffer memory; a playback step for playing the stored data in the buffer memory in parallel with the reception step; a first setup step for setting up a first intermittent transmission schedule which will not cause either overflow or underflow of data in the buffer memory, based on a data characteristic of the data; a proposal step for transmitting the first intermittent transmission schedule to a communication partner side to make a proposal of the first intermittent transmission schedule in order to receive an approval or disapproval of the proposed first intermittent transmission schedule; and an electric power supply stop step for stopping electric power supply to an inter-node communicator during a non-transmission time based on a current intermittent transmission schedule of the data being transmitted intermittently.
