Wireless transfer system

A wireless transfer system comprising:

• a wireless transmission section comprising:
• an input section configured to receive one of a first video signal and a second video signal as an input signal, the first video signal being compliant with a first signal transfer standard provided with, at a head part of a high-definition video signal, ancillary information including at least identification information indicating one of a high-definition 3D video signal and a high-definition 2D video signal, the second video signal having a signal transfer rate lower than the first video signal and being compliant with a second signal transfer standard not including the identification information;
• a video signal extraction section configured to extract one of the high-definition video signal and the second video signal from the input signal;
• an ancillary information extraction section configured to extract the ancillary information including at least the identification information from the input signal;
• a wireless video transmitter configured to wirelessly transmit one of the high-definition video signal and the second video signal extracted by the video signal extraction section;
• a wireless ancillary information transmitter configured to wirelessly transmit the ancillary information extracted by the ancillary information extraction section, separately from one of the high-definition video signal and the second video signal wirelessly transmitted by the wireless video transmitter;
• and
• a control section configured to control operation of the wireless ancillary information transmitter according to an extraction result of the ancillary information;
• and
• a wireless reception section comprising:
• a wireless video receiver configured to receive one of the high-definition video signal and the second video signal wirelessly transmitted from the wireless video transmitter;
• a wireless ancillary information receiver configured to receive the ancillary information wirelessly transmitted from the wireless ancillary information transmitter;
• and
• an output signal control section configured to add the ancillary information to the high-definition video signal and output the high-definition video signal when the ancillary information is received and configured to output the second video signal when the the ancillary information is not received, according to a reception result of the wireless video receiver and a reception result of the wireless ancillary information receiver.
