Daryal, you were correct, and Eldon sent out an email explaining the 'non-switching' switching of the HD signal:
Not sure if you got this or not, so here it is:
Several of you have noticed that we had a switching problem during CSI Thursday night. It was traced back to an operator error. We have a computer automation system that controls our analog switching from program to commercials and back to program. The "playlist" this computer uses is built by our traffic department each and every day as commercials change, and segment times of programs change. We do our best to make this playlist accurate to 1/30th of a second to avoid cutting off the start or end of material, and to avoid a lot of blank time between material.
We are using another channel of this same automation system to control the switch from HD to upconverted video for our digital side. Since we are only concerned with the transition into and out of CBS HD material, this playlist is much shorter (one page verses around 50 pages), and the master control operator is building these playlists each day. As we build each one, we are also building a template for each day for the operator to use next week, so as long as the programs don't change, they will only have to edit the times for the switch into and out of HD. Once these times are inserted and the playlist started, it all happens automatically. Unfortunatly, during CSI the operator forgot to enter that one transition time, so the computer didn't switch back to HD, and the operator didn't notice it. In his defense, this task is one more that has been added to his already busy schedule. We have changed the digital monitors in that room to try to make it easier for him to notice such problems.
I also wanted to let you all know that we plan to be working on our transmitter tomorrow morning. The replacement for the leaking pump is supposed to arrive today and be installed tomorrow. We will be off the air while this is done, and should be back up sometime in the afternoon.
Thank you for your patience,
