Abstract

In a cellular phone applicable as an information processing apparatus of the invention, an audio data transfer control unit controls streaming transfer of encoded audio data to a headset through wireless communication, and a hands-free control unit controls hands-free communication with the headset through wireless communication. Furthermore, a transmitting/receiving unit transmits/receives data to/from the headset in the streaming transfer of the encoded audio to the headset through the wireless communication or in control over hands-free communication with the headset through wireless communication, and a retransmission control unit controls the retransmission of the data to be transmitted to the headset through the transmitting/receiving processing unit.

Claims

1. An information processing apparatus, comprising:

a transfer control unit configured to control streaming transfer of encoded audio data to a terminal through wireless communication;

a hands-free control unit configured to control hands-free communication with the terminal through wireless communication;

a transmitting/receiving unit configured to transmit/receive data to/from the terminal in the streaming transfer of the encoded audio to the terminal through wireless communication by the transfer control unit or in control over hands-free communication with the terminal through the wireless communication by the hands-free control unit; and

a retransmission control unit configured to control retransmission of data to be transmitted to the terminal by the transmitting/receiving unit.

2. The information processing apparatus according to claim 1, wherein the retransmission control unit controls the retransmission of the data so as to prevent delay of data transmission in the streaming transfer of the encoded audio data to the terminal through the wireless communication by the transfer control unit.

3. The information processing apparatus according to claim 1, wherein the retransmission control unit controls the retransmission of the data so as to prevent loss of the data to be transmitted in control over the hands-free communication with the terminal through the wireless communication by the hands-free control unit.

4. The information processing apparatus according to claim 1, wherein the retransmission control unit stops the streaming transfer of the audio data by the transfer control unit and then controls the retransmission of the data so as to prevent loss of the data to be transmitted in control over the hands-free communication with the terminal through the wireless communication by the hands-free control unit during the streaming transfer of the encoded audio data to the terminal through the wireless communication by the transfer control unit.

5. The information processing apparatus according to claim 1, further comprising:

an error occurrence frequency managing unit configured to calculate frequency of occurrence of errors in transmitting data to the terminal by the transmitting/receiving unit and managing the calculated frequency of occurrence of errors; and

a determining unit configured to determine whether or not the frequency of occurrence of errors managed by the error occurrence frequency managing unit is higher than a predetermined reference value,

wherein, in a case that the determining unit determines that the frequency of occurrence of errors managed by the error occurrence frequency managing unit is higher than the predetermined reference value, the retransmission control unit controls the retransmission of the data so as to prevent loss of data to be transmitted in control over hands-free communication with the terminal through the wireless communication by the hands-free control unit, and in a case that the determining unit determines that the frequency of occurrence of errors managed by the error occurrence frequency managing unit is lower than the predetermined reference value, the retransmission control unit controls the retransmission of data so as to prevent delay of data transmission in control over hands-free communication with the terminal through the wireless communication by the hands-free control unit.
