You are building a hotel with 100 rooms. Each room is to have a video-on-demand television that displays movies in HDTV resolution of 1920 X 1080 pixels at 30 frames/s. If each pixel is 24 bits and you can compress video data by a factor of 100, determine the following.
a. What is the maximum bit rate that can be demanded if you assume that, in the worst case, 70% of the rooms will be watching television?
b. What is the required disk storage capacity if the hotel provides 250 movies on demand, each lasting on average 90 minutes?
