(i) Identify the minimum bandwidth requirement for the effective transmission of the video. (ii) What is the ratio of bandwidth deduction if the video is transmitted as monochrome?(i) The minimum bandwidth requirement for the effective transmission of the video can be calculated using the following formula: (resolution (pixels) x color depth (bits per pixel) x frame rate (frames per second)) / 8 (bits per byte)In this case, the calculation would be: (720 x 1080 x 24 x 25) / 8 = 648,000,000 bits per second or 648 MbpsSo, the minimum bandwidth requirement for the effective transmission of the video is 648 Mbps.(ii) To transmit the video in monochrome, the number of bits per pixel would be reduced from 24 to 1. The ratio of bandwidth reduction can be calculated by dividing the original bandwidth by the new bandwidth.In this case, the calculation would be: (648,000,000 (original bandwidth)) / (720 x 1080 x 1 x 25) / 8 = 24So, the ratio of bandwidth reduction when the video is transmitted as monochrome is 24:1</blockquote>
