Q2. A PC plays back moving image data recorded at 500 400 pixels per frame, 30 frames
per second, and 3 bytes per pixel while reading it from a peripheral device. When the
data transfer rate between the peripheral device and the PC is 1106 bytes per second,
in order to play back the moving image without delay, the data must be compressed to
one n-th (1/n) in advance. Which of the following is the minimum value of n? Here,
the time to expand the compressed data and other impacts can be ignored.
