PROBLEM TO BE SOLVED: To provide a reference color signal pattern enabling visually confirming, at the multilink transmission of a high definition video image, the signal connection thereof.SOLUTION: In a reference color signal pattern which includes a pattern including a diagram having a first color region contacting to a second color region at a boundary, the boundary has a step-wise shape composed of the repetition of 1 pixel in the vertical direction with 1 pixel in the horizontal direction, 1 pixel in the vertical direction with 2 pixels in the horizontal direction, 1 pixel in the vertical direction with 3 pixels in the horizontal direction, and 1 pixel in the vertical direction with 2 pixels in the horizontal direction. In the above pattern, the shape or the color of the boundary changes when replacement is made between arbitrary two pixel groups among a pixel group including an odd column and an odd row, a pixel group including an even column and an odd row, a pixel group including an odd column and an even row, and a pixel group including an even column and an even row. |
