SOLID-PICTORIAL VIDEO SIGNAL GENERATING APPARATUS, SOLID-PICTORIAL VIDEO SIGNAL TRANSMITTING APPARATUS, SOLID-PICTORIAL VIDEO SIGNAL RECEIVING APPARATUS AND SOLID-PICTORIAL VIDEO SIGNAL TRANSMISSION SWITCHING APPARATUS

摘要

Left and right video cameras 18L and 18R are disposed on both sides of a front video camera 18M. Solid-pictorial video signals used upon signal transmission are generated by using video signals outputted from the left and right video cameras with respect to a video signal outputted from the front video camera. The left and right video cameras make use of simplified video cameras and are cameras with no zoom functions or the like. The video signals obtained from the left and right video cameras are used as signals for forming a solid picture. In the present example, only solid information with respect to a main picture is transmitted as a video signal to reduce the amount of transmission. Since a motion-compensated DCT encode process using the front video signal as a reference picture is performed to extract only the video signal having the solid information from the left and right video signals. Since the simplified video cameras can be utilized, solid-pictorial video signals can be generated at low cost.
