It uses no upstream bandwidth at all.

It uses about 6 mb/s * 86400 s/day * 1/3 * 30 days/per month / 8 b/B = 0.65 * 10^12 Bytes/month down. That is shared among some percentage of the 500 homes passed by your cable segment (assuming everyone is watching something differently, it is shared by 1).

So month's usage is equivalent of 650 GB of data down, 0.0 GB up is a worst case model for your "typical" digital TV customer, if they never watch what their neighbors watch, and get really high quality (6mb/s) TV.

A question --- How much does a regular cable service take up in bandwidth – yes, I know all of the caveats, but if I watch, say Comcast for the usual 8 hours a day, at the current broadcast bandwidth, how much does that use up?

I know this topic has been discussed at length but below is the official message I received from Comcast.

Dear Comcast High-Speed Internet Customer,
We appreciate your business and strive to provide you with the best online experience possible. One of the ways we do this is through our Acceptable Use Policy (AUP). The AUP outlines acceptable use of our service as well as steps we take to protect our customers from things that can negatively impact their experience online. This policy has been in place for many years and we update it periodically to keep it current with our customers' use of our service.

On October 1, 2008, we will post an updated AUP that will go into effect at that time.

In the updated AUP, we clarify that monthly data (or bandwidth) usage of more than 250 Gigabytes (GB) is the specific threshold that defines excessive use of our service. We have an excessive use policy because a fraction of one percent of our customers use such a disproportionate amount of bandwidth every month that they may degrade the online experience of other customers.

250 GB/month is an extremely large amount of bandwidth and it's very likely that your monthly data usage doesn't even come close to that amount. In fact, the threshold is approximately 100 times greater than the typical or median residential customer usage, which is 2 to 3 GB/month. To put it in perspective, to reach 250 GB of data usage in one month a customer would have to do any one of the following:

* Send more than 50 million plain text emails (at 5 KB/email);
* Download 62,500 songs (at 4 MB/song); or
* Download 125 standard definition movies (at 2 GB/movie).

And online gamers should know that even the heaviest multi- or single-player gaming activity would not typically come close to this threshold over the course of a month."
