Questions:
Bit Rate of Uncompressed Color
1. What is the bit rate for uncompressed full-color XGA running at 25 frames per second? Can a data stream at this rate come off an Ultra Wide SCSI disk?
2. Can uncompressed black-and-white television be sent over fast Ethernet? If so, how many channels at once?
3. HDTV has twice the horizontal resolution of regular TV (1280 vs. 640 pixels). Using information provided in the text, how much more bandwidth does HDTV require than regular TV?
4. Assume a CD holds about 74 minutes of music or 650 MB of data. Estimate the compression factor for music.
5. A recording studio makes master digital recordings using 20-bit sampling. The final distribution to consumers uses 16-bit sampling. Estimate the quantization noise. Suggest a way to reduce it, if necessary.
6. The CPU of a video server has a utilization of 65%. How many movies can it show using RMS scheduling?
