Re: Right direction
said by gatorkram  :This is the right direction to be moving. If broadband speeds keep getting higher, sooner or later the old outdated TV model will be gone... 3rd party IPTV content will never be scalable for anything more than niche content. Most of what the public knows as IPTV today is done in unicast IP streams, which means that the bandwidth grows linearly as the number of viewers grows. Say you can get an HDTV feed in 1mbps of bandwidth (it's certainly going to be higher than that, but this makes the math easy). For shows like American Idol to be viewed using this technology you would need to meet peak demands of 35-40 million viewers. That's 35,000,000 - 40,000,000 megabit, or 35-40 terabit of bandwidth on the head-end programming source just to distribute content for a single program.
The only way IPTV makes sense en mass is using IP multicast, where your ISP would get a single 1mbps feed for that program and then copy the packets in their network to any end-device that joins the multicast group. Since this requires significant configuration in the network, and broadband networks are also owned by companies selling entertainment via traditional methods, 3rd party mass media distribution via IP is unlikely to ever gain full scale adoption.
Television broadcast coupled with DVR time-shifting functionality will likely continue to be the direction of choice because of the efficiency of the delivery method. |

Bit torrent is an advanced form of this ... no it'll never take off

Television broadcast coupled with DVR time-shifting functionality will likely continue to be the direction of choice because of the efficiency of the delivery method. Good analysis. Multicast is the only practical possibility for IPTV of mass market shows. And as you point out, even that is unlikely for the foreseeable future.

said by gaforces :Bit torrent is an advanced form of this ... no it'll never take off Case in point. BitTorrent, while it has gained considerable popularity over the years, still only had reached adoption by a small percentage of the Internet community as whole. Studies like »www.ipoque.com/media/internet_st···udy_2007 place BT adoption rates at roughly 20% of all Internet users. Even with that relatively small percentage the impact from such traffic has spawned an entirely new industry of companies that make products just to limit P2P effects on networks. BT has scalability issues just like IPTV. |

‘Do ye, quieting in your bosoms your strong hearts,
Who of many good things have had your fill even to surfeit,
With what is moderate nourish your mighty desire; for neither will
We yield, nor shall you have all else as you wish.’
