Abstract:
1. A communication apparatus comprising: a multiplexed data receiving unit for receiving multiplexed data at least including audio data; an extracting unit for extracting the audio data from the multiplexed data; a telephone unit for transmitting/receiving telephone audio data; an audio output unit for inputting one of extracted audio data that was extracted by the extracting unit and received telephone audio data that was received by the telephone unit, and outputting one of the extracted audio data inputted and the received telephone audio data inputted; a switching control unit for switching an input to the audio output unit between the extracted audio data and the received telephone audio data; and an instructing unit for detecting a receive event generation, a send event generation, and an end event generation, and giving a prescribed instruction to the telephone unit, the extracting unit, and the switching control unit, wherein the instructing unit, in a case of detecting one of the receive event generation and the send event generation while the multiplexed data is being received by the multiplexed data receiving unit, transmits a telephone audio data transmission/reception start instruction to the telephone unit to start transmitting/receiving the telephone audio data, transmits an audio data extraction stop instruction to the extracting unit to stop extracting the audio data from the multiplexed data, and transmits a received telephone audio data switch instruction to the switching control unit to switch to the received telephone audio data, and in a case of detecting the end event generation while the multiplexed data is being received by the multiplexed data receiving unit, transmits a telephone audio data transmission/reception stop instruction to the telephone unit to stop transmitting/receiving the telephone audio data, transmits an audio data from the multiplexed data extraction start instruction to the extracting unit to start extracting the audio data, and transmits an extracted audio data switch instruction to the switching control unit to switch to the extracted audio data, wherein the telephone unit, in a case of receiving the telephone audio data transmission/reception start instruction from the instructing unit, starts transmitting/receiving the telephone audio data, and in a case of receiving the telephone audio data transmission/reception stop instruction from the instructing unit, stops transmitting/receiving the telephone audio data, wherein the extracting unit, in a case of receiving the audio data extraction stop instruction from the instructing unit, stops extracting the audio data from the multiplexed data, and in a case of receiving the audio data extraction start instruction, starts extracting the audio data from the multiplexed data, and wherein the switching control unit, in a case of receiving the received telephone audio data switch instruction from the instructing unit, switches the input to the audio output unit to the received telephone audio data, and in a case of receiving the extracted audio data switch instruction from the instructing unit, switches the input to the audio output unit to the extracted audio data.
