RE: Level 3 Communications Issues Statement ConcerningComcast'sActions

[Ben Butler <ben.butler () c2internet net>]

Ok, you have a point with SD vs HD which is encoded at 8 rather than 2 on our digital terrestrial and satellite 
broadcasters in the UK.

So why 24mb or 50mb access speeds, what is it actually being used for, I do not believe that streamed video is the 
culprit here with most codecs doing about ~700 kbits.

Part of the problem is the content providers do not encode properly, we have seen this all along with images on webs 
sties as access speeds have increased.  There is no penalty on the content provider for lazy programming, cpu cycles or 
codec licensing to stop them making the access network carry larger streams than nessacery.

And before we get too much into HD vs Codecs vs 720P vs 1080p vs "true HD" marketing BS, I capture out of my camera's 
HDMI port at 3Gbit/s and I am not running 4:4:4 color.  So what is HD and what it the allowable compression for it 
still to be considered as such.

I say otherwise.

So do many customers who want 720 or 1080 lines on their TV.

So do many content providers who want to satisfy their customers.

But it is your network, your rules.  If your customers do not want "HD quality", and are happy with 1.5 Mbps streams 
per DSL line, that's between you & your customers.  Of course, if your customers want more, that's between your 
customers and your competitors....
