Confused Over HDMI 1.3 and Monster's Cable

[bd_noob09]

I'm finally buying a Blu-Ray player and need to purchase a HDMI cable. As my Sony LCD only supports 10-bit color and is 60hz, I guess I don't need anything too fancy. However, I'm very confused over HDMI Version 1.3 standards and options.

If a HDMI cord conforms to 1.3 standards, is it required to support 10.2 Gbit/s or is this just an option? I ask because according to Monster:

"Take 1080p video with advanced 12-bit color, also called Deep Color, available right now from the PlayStation® 3. To experience this level of high definition performance, your HDMI cable must exceed the requirements of the HDMI 1.3a, CAT 1 specification, and support an astonishing cable data rate of 6.68 Gbps."

HUH?

Also, what calculations are they making in order to get these figures on this graph?

As in how does Monster factor that a 12-bit signal @ 120hz requires 14.93Gbit/s?

I'm very confused...
