Abstract
In a video signal transmission device, a camera control device includes: a compression unit for compressing a return video signal; a compression/expansion unit for compressing/expanding a prompter video signal; a frame synthesis unit for synthesizing the video signals; an encoding unit for encoding the synthesized video signal; and a modulation unit for modulating the encoded video signal and transmitting the modulated video signal to the camera adaptor. A camera adaptor includes: a demodulation unit for demodulating the video signal from the camera control device; a decoder unit for decoding the demodulated video signal; an expansion unit for separating one video signal from the decoded video signal, expanding the video signal, and restoring the video signal to the return video signal; and an expansion/compression unit for separating one video signal from the decoded video signal, compressing/expanding the video signal, and restoring the video signal to the prompter video signal.
