Abstract
A transmission apparatus includes a video obtainer configured to obtain a video signal, a first converter configured to convert the video signal into an electrical signal complying with a high definition multimedia interface (HDMI (registered trademark)) standard, a second converter configured to convert the video signal into an optical signal, and a signal processor configured to perform at least one of the conversion using the first converter and the conversion using the second converter with respect to the obtained video signal.
Claims23
A transmission apparatus comprising:
- a video obtainer configured to obtain a video signal;
- a first converter configured to convert the video signal into an electrical signal complying with a high definition multimedia interface (HDMI (registered trademark)) standard;
- a second converter configured to convert the video signal into an optical signal;
- and
- a signal processor configured to receive the video signal from the video obtainer and to perform the conversion of the obtained video signal using the first converter and the conversion of the obtained video signal using the second converter,
- wherein the signal processor is further configured to perform video separating processing of the obtained video signal by:
- separating the obtained video signal into a first video signal forming a first frequency component of an image contained in the video signal and a second video signal forming a second frequency component that is contained in a frequency component of the image, the second frequency component belonging to a band higher than a band to which the first frequency component belongs,
- converting the first video signal into the electrical signal using the first converter, and
- converting the second video signal into the optical signal using the second converter.
A reception apparatus that outputs a signal obtained by reconstructing a video signal, the reception apparatus comprising:
- a first reconstructor configured to obtain an electrical signal complying with a high definition multimedia interface (HDMI (registered trademark)) standard and containing a first video signal as part of the video signal and reconstruct the first video signal by using the obtained electrical signal;
- a second reconstructor configured to obtain an optical signal containing a second video signal as part of the video signal and reconstruct the second video signal by using the obtained optical signal;
- and
- a combiner configured to generate a combined video signal by combining the reconstructed first video signal and the reconstructed second video signal and output the generated combined video signal as a reconstructed signal.
A transmission method, comprising:
- obtaining a video signal;
- separating the video signal into a first video signal forming a first frequency component of an image contained in the video signal and a second video signal forming a second frequency component that is contained in a frequency component of the image, the second frequency component belonging to a band higher than a band to which the first frequency component belongs;
- converting, using a first converter, the first video signal into an electrical signal complying with a high definition multimedia interface (HDMI (registered trademark)) standard;
- and
- converting, using a second converter, the second video signal into an optical signal.
A reception method executed by a reception apparatus configured to output a signal obtained by reconstructing a video signal, the method comprising:
- obtaining an electrical signal complying with a high definition multimedia interface (HDMI (registered trademark)) standard and containing a first video signal as part of the video signal, and reconstructing the first video signal by using the obtained electrical signal;
- obtaining an optical signal containing a second video signal as part of the video signal, and reconstructing the second video signal by using the obtained optical signal;
- and
- generating a combined video signal by combining the reconstructed first video signal and the reconstructed second video signal, and outputting the generated combined video signal as a reconstructed signal.
