Assuming there are 100 million households in the US, and that each household has two HDTVs, and that each TV is used to watch 4 hours of video per day. We’ll assume that each (compressed) video streams at 2Mb/s. If all households are watching both TVs at the same time, and all are watching video on-demand (i. e. data is delivered unicast to every household), then which of the following is the closest approximation of the total peak aggregate data rate delivered to all homes? 100 Tb/s (100 × 10^12b/s),
400 Tb/s (400 x 10^12b/s),
1 Pb/s (1 x 10^15b/s),
100 Gb/s (100 x 10^9 b/s),
2 Tb/s (2 x 10^12b/s)
