A large number of things need to be worked out still at this point. The kings have reserved Mira mobile's M5 HD truck, which is still under construction at this point, to do the games. How they will get the video to Comcast and KXTV is still TBD as of today. There are meetings between the parties scheduled next week to start working this out. I would guess that they will use a KU band satellite truck to distribute the HD signal. There potential issues with the relative delay between the HD and SD feeds assuming that they send both.
In the past KXTV has inserted the commercials in the game feed but obviously that will not work for games that are on Comcast only so they may need to start rolling in the spots in the truck. No decision has been made between 720P and 1080I at this point (the truck can do either).
With some luck we will have some of these questions answered at the end of next week. We need to know ourselves so any required equipment can be purchased, installed, and checked out well in advance.
