Cable is of much higher bandwidth than twisted-pair phone line, so the most
promising media for IP high bandwidth services.
Fibre is super as well, but will cost a fortune to deploy the infrastructure.
So only big one like Verizon may be able to afford it.

I think there are two groups here
Cable : Comcast, TimeWarner/Adelphia, Cox, and other small ones
Cable TV (traditional, even with digital)
VoIP (packetCable.com?)
Internet (Data) speed surely higher than dsl, but similar to FIOS
Telecom: Verizon/MCI, ATT/SBC/BLS
IPTV (most use Microsoft product?)
Internet (DSL not so good in most places, FIOS is an exception)
PSTN: (shrinking?)
Anyone has access to gartner? they should have nice pie chart of these

Broadwing跟qwest是最大的两家有dark fiber的公司？俺倒不知道这个。
telecom一般都有自己的backbone，cable公司一般都很分散，零乱，有自己backbone的据
俺所知只有comcast一家。
iptv虽然没有什么特别新的技术，但是涵盖的面非常广，从运营结构上看，有super head
-end, CO/VSO，super headend主要做传统的headend的活，最重要的就是encoding，同时
进行multicast tv programes，一套iptv网可能只有1个，或者最多2个（座reduntancy）
，vso做的事情比较杂，最重要的可能就是VoD了，都是unicast的traffic
从component方面看，主要分application, service, and network，每个layer都有很多
东西在里面，俺是搞网络的，所以最关心的是network，也略微了解一点service，至于
application就不关俺的事情了。
大致说了这么些，大家可以把每个东西都拿出来讨论

have more of their customers to buy tel. service than telecom
have their customers to buy TV service. In this new IPTV area,

Comcast is the only big one I know.
Currently Telecom can hardly take biz from cable, the reverse is true. Telecom
is desperate finding a way to reach each home with fibre, like cable has been
able to with coaxial cable.
But mass deployment of IPTV service is still a far far call. Cable is yet to
go completely digital by 09? The techs have been there. What's missing is the
capital & the necessity of conversion.
