The present invention provides a novel head-mounted display on which a video image received through wireless communication at a predetermined frequency is displayed, a display controlling apparatus, a display controlling method, and a program. A video image receiving section (94) receives a video image from an entertainment apparatus (14) through wireless communication at a predetermined frequency. A display controlling section (96) causes the video image received through the wireless communication at the predetermined frequency to be displayed on a display section of an HMD (12) in the case where it is decided that a user mounts the HMD (12). A display controlling section (96) causes a video image acquired by using a method other than reception in the video image receiving section (94) through the wireless communication at the predetermined frequency to be displayed on the display section of the HMD (12) before the video image received by the video image receiving section (94) through the wireless communication at the predetermined frequency is caused to be displayed on the display section of the HMD (12).

The present invention provides a system for frequency modulation of high definition composite video broadcast signals in a wireless transmission environment and a method thereof, comprising: a transmitting unit and a receiving unit. An image sensor of the transmitting unit converts an image to a digital signal. A signal processor converts the digital signal to a composite video broadcast signal. A frequency modulator modulates the composite video broadcast signal to a first modulated signal. The receiving unit receives the first modulated signal. A low noise amplifier converts the first modulated signal to a second modulated signal. A frequency demodulator restores the second modulated signal to the composite video broadcast signal. After an image decoder decodes the composite video broadcast signal, the image decoder outputs a digital signal in a specific format.

Provided are an optical transmission system in which one can easily set a video signal cable, and an adapter that can be used in this system. There is provided an adapter for use in an optical transmission system in which an analog video signal or a digital video signal is transmitted between a pair of adapters using light. The adapter includes a first signal determination unit configured to make a determination as to whether a first electrical signal inputted to a common input terminal is an analog video signal or a digital video signal.

Instead of compressing and packetising video information before applying quadrature amplitude modulation (QAM) to encode data bits into orthogonal frequency division multiplexing (OFDM) symbols which are ultimately transmitted as radio frequency (RF) signal bursts, this invention uses pixel color intensity data (which is still digital), and a novel method of mapping digital video information into OFDM symbols based on a similar approach to classic QAM, to transmit video by avoiding compression and error correction, in order to receive and demodulate RF waveform in a way which is more noise-tolerant than traditional approaches.
