Re: Defintely overly optimistic

I would be curious to know what the two of you are thinking you know. SDTV channel using VC1 or MPEG4 is 2Mbps. Using the same video codecs, HDTV would be 8-Mbps. A 64-128 Kbps using the same QoS as the Video is all that it takes for reliable VoIP.

And no, the existing DSLAMs and routers are not the target elements in the IPTV equation. Much lager DSLAM-to-Headend backhauls are planned. Next generation Alcatel DSLAMs terminate IP.

And the biggest consumer on the pipe will be video, which is only in one direction.

And your qualifications are what ?

Higher quality video, in order to compete with cable first requires at least on the order of 10Mbps per stream...

As well, you have to consider multiple video streams for multiple devices (ie televisions, TIVOs, etc.)...
