Re: Only people really affected are video streamers

said by Kearnstd:

anyway back on topic, so much for my plans to get a smart phone, ditch XM and just use internet radio all the time in the car. as i figure other carrier smartphone plans will go a similar route. if only there where a way to see how much my stream sucks down on its own. anytime i am home i am listening to a station that runs at 128kbit mp3.
According to Apple's Development streaming FAQ audio streaming over 3G is limited to 64 kbps. That would give you about 72.8 hours of 3G audio streaming before you hit the 2 GB cap. I think video streams are limited to about 150 kbps, which would be about 34 hours to hit 2 GB.

So I'll need to expand my original post to any kind of streaming, video or audio.

Where is my math wrong? 2GB = 2,000,000,000 bytes approximately, right? 64kbs = 64,000 bits per second approx, right?

So 2 billion / 64 thousand = 31250 seconds.

31250 / 3600 = 8.6 hours.

Is that not right?

**** Edit **** already figured out the error above, comparing bits to bytes.

8 bits to a byte.

64kilobits per second = 8 kilobytes per second.

You're right. I realized that after I submitted

You divided Bytes/bits, so your time calculation is wrong. 64,000 bits = 8,000 bytes.
Then cacl should be 2 billion / 8 thousand = 250,000 secs
250,000 / 3600 = 69.4 hours
