Re: Holy cow, Netflix really does use a lot of bandwidth ...

Yea, I know when I was watching LOST on Netflix and I was watching 7-8 hours a day... trying to catch up for the next season I was getting a good 10-15 GB consumption per day. Like I said I can see how its possible but you would really have to try is all I'm saying.

Until we have 2, 3 or 4 sets running IPTV. Then it may not be as difficult.

Another data point. I just finished watching "Outsourced" via Netflix instant streaming. It is an HD movie. I took a snapshot of the traffic at the beginning and the end of the movie. The numbers are:


Date Time Downstream Upstream
Apr 18 13:36:22 4,562,200,162 562,646,050
Apr 18 14:00:01 5,326,113,698 574,868,378
Apr 18 15:00:01 7,120,817,370 604,758,131
Apr 18 15:20:57 7,633,710,744 613,650,259


Looks like about 3.1GB for the hour and 42 minute movie.

And google calls that...
(3.1 gigabytes) / (102 minutes) = 531.141438 kBps

which is....

((3.1 GB) / (102 minutes)) * (60 minutes) = 1.82352941 gigabytes

Per hour.

Or, pretty much in the old ball park.

That difference is 3072 MBytes.

Using VPC1 HD rate of 3.8 Mbits/Sec, WMA 2.0 Audio Encoder rate of 220 kbits/Sec including protocol overhead sums to an aggregate rate of 4.02 Mbits/sec.

102 minute movie is 6120 seconds in length.

The movie has a total size of:
4.02 Mbits/Sec * 6120 Sec = 24,602 Mbits.

Converting from bits to Bytes:
24,602 Mbits / ( 8 bits / 1 Byte ) = 3075 MBytes or 3.075 GBytes.

So all the math works as expected within an error factor of 1*10^-4

That rate can be generalized to 1809 MBytes/Hour ... for now.

Later this year Netflix is supposed to start streaming multichannel audio which will bump up the audio rate between 250 and 500 kbits/sec. That moves the aggregate rate for an HD movie to 1935 Mbytes/Hour.
