Level 3 Communications Issues Statement ConcerningComcast'sActions

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....
