Suppose a camera has 450 lines per frame, 520 pixels per line, and 25 Hz frame rate. The color-subsampling scheme is 4:2:0. The camera uses interlaced scanning, and each sample of Y, Cr, Cb is quantized with 8 bits. What is the bit-rate produced by the camera? Suppose we want to store the video signal on a hard disk, and, in order to save space, re-quantize each chrominance (Cr Cb) signals with only 6 bits per sample. What is the minimum size of the hard disk required to store 10 minutes of video? Repeat the exercise (both questions) assuming color subsampling scheme 4:2:2
