Assignment:

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?

c. When a viewer selects a new movie, the server is interrupted and an appropriate routine is executed. The switching routine is composed of approximately 15,000 instructions that take approximately one cycle/instruction on a processor running at 4 GHz. If a user can cope with a latency of 80 ms (i.e., a delay in the data stream of less than 80 ms is not visually disturbing), how many simultaneous switch-overs can the system handle at any instant?

Please add an explanation I have been getting different answers from everyone I have asked.
