Split miracast transmission over multiple frequency bands
First Claim
1. An information processing apparatus that performs data transmission by using at least one of a wireless transmission channel of a high frequency band and a wireless transmission channel of a low frequency band, and performs real time image transmission with another information processing apparatus in accordance with a wireless fidelity (Wi-Fi) certified miracast specification, the information processing apparatus comprising:
- a control unit configured to perform a control to transmit a control signal relevant to Wi-Fi certified miracast to the other information processing apparatus, by using the wireless transmission channel of the low frequency band,wherein when transmitting multiple data to the other information processing apparatus by using both of the wireless transmission channel of the high frequency band and the wireless transmission channel of the low frequency band, the control unit generates one TCP session on the wireless transmission channel of the low frequency band, and generates a plurality of RTSP sessions for transmitting the multiple data on the TCP session,wherein different IP addresses are used for the wireless transmission channel of the high frequency band and the wireless transmission channel of the low frequency band,wherein transmission of data using the channel of the high frequency band is controlled by one of the RTSP sessions and transmission of data using the channel of the low frequency band is controlled by another of the RTSP sessions.
