Abstract:
1. A short-range wireless communication apparatus comprising: an own connection device that is capable of connecting a sound data transfer protocol, which has a function of reporting a streaming status concerning sound data, and a control data transfer protocol, which has a function of reporting a play status concerning the sound data, to a communication destination side connection device of a communication destination apparatus via a short-range wireless communication line; and a control device that identifies state of the communication destination apparatus based on the streaming status reported from the communication destination side connection device with use of the sound data transfer protocol and the play status reported from the communication destination side connection device with use of the control data transfer protocol, wherein: when the control device determines that the streaming status reported from the communication destination side connection device with use of the sound data transfer protocol is an output-in-progress state indicating that a channel for the sound data transfer protocol is open, the control device identifies the state of the communication destination apparatus by preferentially following content indicated by the play status reported from the communication destination side connection device with use of the control data transfer protocol; and when the control device determines that the streaming status reported from the communication destination side connection device with use of the sound data transfer protocol is a stopped state indicating that the channel for the sound data transfer protocol is closed, the control device identifies the state of the communication destination apparatus as one of a temporarily-stopped state and a stopped state in accordance with content indicated by the play status reported from the communication destination side connection device with use of the control data transfer protocol.
