Re: Makes little sense
And how will that change with 3.0? |

Piscataway, NJ | 480 Mbps will be shared between 250-2000 houses. It is much better. BTW, I think, that is why they still offer only 160Mps, not full 480Mpbs, so one user cannot overload the node. |

With DOCSIS3.0 users will share +480Mbps instead of 42Mbps. ALL 2.0 cable modems sync at 48Mbps down (5360 Ksym/sec) 20Mbps up (2560 Ksym/sec) Time slots (provisioning) is what defines your speed. |

10 out of 40 is 1/4 of the bandwidth by one person.
160 out of 480 is 1/3 of the bandwidth by one person.
It is the same problem just a bigger pipe. Percentage wise things are worse not better. 1/3>1/4 |

| Maybe, but I would bet that is a bad assumption. With the coming shift to HD DVD or Blueray (regardless of which wins out) people will be downloading 25-50gig images instead of 4.4-9gig images. With the switch to DTV in Feb 09 will will be seeing a lot more TV series being sent in HD rather than smaller standard NTSC (yes I know cable does not have to change but I bet it will). Lower resolution stuff in general has been dropping (VCDs are relatively rare already). Even web pages themselves are becoming (or have become) much higher resolution (larger). P2P just keep on growing. Every time more bandwidth becomes available people have found a way to fill it. I do not think that is a trend that is going to change anytime soon. As far as pure data is concerned look at the explosive increases in data set sizes every time a new media became popular: Cds, DVDs, and now whichever format wins out. |

| said by Lazlow  :That is for video signal not video files. Once again ... you're being too ________. SDV obviously does help with video files that are sent in such video signals. It fixes it. It deals with the entire video file problem. Jesus. So does DOCSIS 3.0. |

Saint Louis, MO | We are talking about sending video files on HSI, (avi, mpeg, rar etc). Not video like VOD. |

Yes, I meant the same. And I think, actually QoS settings in modem decides speed in 2.0. But in DOCSIS3.0 it is not necessary to bound all channels together. As far as I understand you can have 2 pairs of 4 channels bounded, so two modems can transmit at the same moment of time. But I have not seen a very detailed article on DOCSIS3.0, but that one is a bit better than rest of them:

Yeah, but piracy is still a small percentage of HSI users, and web pages probably won't grow as fast as the shift from DVD to HD which is a 10 times increase. I mean how much more flash content can they put on some of these overbloated pages? |

2 edits | I think you are VASTLY underestimating Usenet and P2P. Usenet has to have in excess of 500gig posted a day, with most of the major newshosts holding for 200days. I just looked at one of the Usenet index sites and there are 50 pages (75 filesets/page) of filesets (DVDS) larger than 2500mb and that index does not include all the groups in Usenet. How many times that 500gigs gets downloaded no one is really saying, but I would bet that it is well over 1000 times. That is of course spread over the entire internet (up and down). The P2P situation must be even more significant or the isps would not be attempting to block it.
I would like to point out that not all these materials are pirated. Many new artists release there work on both these venues in an attempt to get known. Many smaller projects (think Linux) also use these methods to spread their work.
Take a look at sites like youtube, google video, and the horde of others like them. Take a look at virtually any TV station's web site and you will see tons of videos from the local news. All these will be shifting to higher quality video (larger files). |
