Debate about Bandwidth Usage

On the Internet, which uses more bandwidth…

Streaming Video or Streaming Audio??


I am staying out a hotel out of state, and having troubles getting a good Internet connection. The property manager admitted tonight that they are lacking in capacity, but also said that people who watch movies online - like NetFlix - are the ones really slowing things down and possibly violating usage terms.

When I mentioned that I listen to radio shows on the Internet he quickly said, “Well, that is as bad as watching streaming movies!”

I don’t believe that is correct.

Does anyone know what the correct answer is?

Video = ~25 images per second + audio
Audio = audio

See what I’m getting at? :wink:

What he said, though it really does depend on encoding and bitrate.

Said hotel should probably invest in a fatter pipe and some network management gear.

Yes, probably meant that high definition time-based live multimedia streaming is extremely hungry in general because of the protocols it uses rather than say visiting SP.

Huh?

I asked which uses more bandwidth… Streaming Video or Streaming Audio.

(I cannot believe that Streaming Audio uses anywhere close to what Streaming Video does?!)

Does anyone know what is the average bandwidth usage for something like YouTube or Netflix?

How about for streaming audio (e.g. WNDT-FM or [URL=“http://www.1029thehog.com/”]WHQG-FM)?

Debbie

Of course it all depends on the bitrate used, but in general video uses a lot more data than audio streams.

For example I just watched a video on YouTube (HD 720p) and that uses ~1.5MB/sec, while listening to a radio station via iTunes uses ~30KB/sec.

See attachment for a screenshot of my bandwith monitor.

How did you get that graph and measure actual bandwidths?

Anyone else care to contribute some hard numbers?

Debbie

It’s a windows7 sidebar widget: Network Meter :slight_smile:

Is there anything comparable for us Mac users? :-/

Maybe something open-source?

(I would love to should the property manager - in real time - that my streaming audio is NOT to blame…) :rolleyes:

Debbie

I don’t own a mac so I have no idea, but a google search for “bandwidth monitor mac” turns up more results than you ever wished for :slight_smile:

I was referring to the owner (complaining) I missed out the word [he] but those things tend to happen when you are word-blind. He was correct in a sense regarding time-based live multimedia streaming generally consuming several times more bandwidth than casual surfing. He was making a generic statement I would assume.

Like was mentioned several times before usually such video typically contains an audio and visual track combined thus usually has a higher overhead than audio alone. They make use of different protocols too, which also effects throughput. Then you have the perceived slowdown due to the very nature of the format itself - nobody wants clunky frame rate and chopped-up sound (latency).

No, I think he thinks there is no difference between me listening to a radio station online and him watching Netflix on real-time on his pc at home.

(If anyone is “hogging” bandwidth where I am staying at, I am certainly not to blame for listening to streaming radio stations online!) :rolleyes:

Do you know of any hard numbers (or references to them) that I could show him?

Or do you know of anything for my MacBook that I could install to show him that it isn’t me that is the issue?

Debbie

The only real hard number here is the actual consumption. I’m sure there are programs that can count that for a Mac, have you checked out the app store?

In terms of a printed number, that really doesn’t work – netflix especially uses variable bit rates to “tune” the quality of the stream to your connection, though they might well publish some minimums on their tech support page. Audio is typically easier to judge – just look at the bitrate of the stream as they tend to be constant.
