Abstract
A method capable of displaying high quality video images although a video capture device and a video display device are of different scanning types is disclosed. For example, a method for outputting video data in a video monitoring system outputting channel video signals of an interlaced scanning type captured by one or more cameras to a video display device of a progressive scanning type, comprises the steps of: scaling each channel video data of the interlaced scanning type digitally converted with different horizontal and vertical scaling ratios; storing the scaled video data for configuring one display screen in a memory; and outputting and displaying the stored video data corresponding to the one display screen to the video display device of the progressive scanning type.

A method for outputting video data in a video monitoring system outputting channel video signals of an interlaced scanning type captured by one or more cameras to a video display device of a progressive scanning type, comprising the steps of:
- a) scaling each channel video data of the interlaced scanning type digitally converted with different horizontal and vertical scaling ratios;
- b) storing the scaled video data for configuring one display screen in a memory;
- and
- c) outputting and displaying the stored video data corresponding to the one display screen to the video display device of the progressive scanning type.
A method for outputting video data in a video monitoring system outputting channel video signals of an interlaced scanning type captured by one or more cameras to a video display device of the interlaced scanning type, comprising the steps of:
- a) scaling each channel video data of the interlaced scanning type digitally converted with different horizontal and vertical scaling ratios;
- b) storing the scaled video data for configuring one display screen in a memory;
- and
- c) outputting and displaying video data corresponding to an even line of the stored video data as video data corresponding to an even field, and outputting and displaying video data corresponding to an odd line of the stored video data as video data corresponding to an odd field.
