Patent ID: 7672569

Claim:
A video signal recording transmitter comprising: an input unit for inputting video signals of plural channels; a video signal input switching unit for switching and outputting the video signals of said plural channels in time division; a first video signal compressing unit for compressing an output from the video signal input switching unit; a recording unit for recording an output signal from the first video signal compressing unit to a recording medium; a second video signal compressing unit for compressing an output from said video signal input switching unit with a high compressibility in comparison with said first video signal compressing unit; a communication unit for transmitting an output signal from the second video signal compressing unit to another device; a channel selecting control unit for controlling the operation of said second video signal compressing unit so as to selectively compress a specific channel included in the output of said video signal input switching unit; a unit for receiving a zoom processing assigning signal from a monitoring device; and a zoom processing circuit for enlarging and processing a predetermined portion of an image in accordance with the zoom processing assigning signal, wherein the video signal which is input to the second video signal compressing unit is input to the second video signal compressing unit after going through the zoom processing unit, and the video signal which is input to the first video signal compressing unit is input to the first video signal compressing unit directly, wherein the second video signal compressing unit processing is performed after the predetermined portion of the image is enlarged and processed on the basis of the zoom processing assigning signal; and wherein video signals for zoom processing are automatically selected and processed by the zoom processing circuit without user input.
