Abstract
To mix video signals of plural channels in time division and record these video signals onto a recording medium, as well as to select and transmit the video signal of a specific channel to a terminal device at a remote location, there is a video signal switching unit for mixing the video signals of the plural channels in time division; a first video signal compressing unit for compressing the mixed video signals from the video signal switching unit; a unit for recording the video signal compressed by the first video signal compressing unit into the recording medium; second video signal compressing units for selecting a channel from the mixed video signals and compressing the video signals with a compressibility higher than that of the first video signal compressing unit; and a unit for transmitting the video signal compressed by the second video signal compressing unit to a remote location.
