Netflix bandwidth - Is 1GB/hr at HD accurate? (I posted this somewhere, don't see it here)
I called NetFlix yesterday. Answered fast, nice gal.
She said their streaming is about 1GB/hr at HD.
I am trying to find a user with a good router based meter who can verify. I'm not looking to prove my point, so much as find the truth. If that number it right, it does take down my concern quite a bit, and my multiple TiVo movie watching example turns into a chunk of usage but not my original, much larger numbers. |

NetMeter should do the trick.
I doubt 1 GB/Hr. because that's what NetFlix's SD videos currently do. With another 70% (?) or so of screen to fill, I would expect that HD numbers would be correspondingly higher.

The above link I just found. I'm running out of the house right now but if someone wants to do the math into Mbps, you're welcome to it.

kudos:1 | From earlier in the thread: »Netflix: $.05 to Deliver Movie Stream?
..... With the average encoding rate for video streamed to the XBOX 360 around 2000Kbps, one person watching a two hour movie would transfer around 1.8GB of data. Of course that's low-def -- the average encoding bitrate for an HD film is around 3200Kbps, and one user would transfer about 3GB of data per film.....

From the blog
quote:
The VC1 encoders are more efficient than the WMV3 encoders, so we are currently encoding VC1AP at slightly lower birates: 375, 500, 1000, and 1500kbps, all square pixel.
SD best encode rate is 1500kbps (thats bits per second)
Google says
(1500 kb * 60 * 60) / 8 = 82.3974609 megabytes an hour.
quote:
settled on second-generation HD encodes with VC1AP at 2600kbps and 3800kbps
(3800 kb * 60 * 60) / 8 = 208.740234 megabytes an hour
Or much lower then we thought. Which indeed proves netflix streams are crapola  |

kudos:1 | Well, that's one way to calculate it, but a gigabyte by international treaty is 10**9.
Somebody got a really bad precedent started years ago when they introduced the 1024. Novell made a nightmare when they released a version where some of the utilities used 1000 and others 1024. The standards folks tried to straighten it out by introducing ki, Mi, Gi for the binary equivalent. Almost nobody uses them. |

So back to our original .33GB and 1.5GB give or take a few. I'm not going around the track again. |

None of the Comcast Cap defenders have anything to say about how Cox can offer uncapped Docsis 3.0 service while Comcast cannot do the same?

Everyone is hoping you might stop some day and move on from reposting the same old things over and over.
Wish I could get Comcast!  |

4 edits | Your Screenname is Comcast Rocks, yet you admit that you wish you could get Comcast.
I'm befuddled.
Next you say that you speak for everyone.
Really?
Instead of attacking me, why don't you respond to what I've said in a Bandwidth Limits Topic in a Comcast Forum on DSLReports?
EDIT: Actually, it's quite kind of you to reply... that way he can see what he's missing! |

SI units, dating from 1960, came about under the provisions that original treaty of the meter. Giga is absolutely 10**9. |

kudos:1 | I'm not trying to pick a fight, but people will be misled.
Microsoft operating systems use 1024 for file sizes.
Memory uses 1024.
Hard drives use 1000 - there was quite a lawsuit over this.
All communications uses 1000. A T-1 line 1.544 Mbits, exactly 1,544,000. Same for the all Ethernets.
Fiber speeds use 1000.
When you buy a circuit it is specified in 1000's and the usage is billed in 1000's.
You can count on Comcast's cap as being 250*1000*1000*1000 Bytes.
I believe I got the abbreviations wrong in my earlier post.
1024*1024*1024 is GiBi. |

Here are some screen caps of Tomato while I was watching Southpark Season 9 Episode 2 - "Die, Hippie, Die" LOL. Next I'll watch 30 Rock and post screen caps again. So for SD, it seems to be around 850 MB/hour for SD.
EDIT See the attached graph of 30 Rock HD Stream. It is more than 1GB/hr for sure. It was around 660 MB for about 21 minutes of HD video. It dropped to zero kb/sec for the last 5 minutes. so, 660/21 = 1885 MB/hr for HD
If anyone has a way to show how much data has been transferred in the last x number of minutes, that would be awesome. With Tomato, I have to take these 10 minute windows and do math. Hopefully I am close to being accurate. |

They can't because it will vary movie to movie (netflix uses a variable rate encode, depends on amount of motion in movie)
Also, netflix streams at a higher bitrate then the playback rate (ie, you download a 2 hour movie in about 100 minutes), so the "higher" number above is misleading, as the last 20 minutes of a movie will be 0 bytes downloaded.
As a general rule, figure on 1.5GB/hour and you'll be close enough. |

Here's what Netflix says they do:
»blog.netflix.com/2008/11/encodin···ing.html
(This has been posted before according to BBR)
The delivery rate is controlled by your player and the capabilities of your connection as explained in the article.
If you are able to use the fastest rate, 3800kbits/sec, it comes to 1.71 GBytes/hour. |
