We are trying to setup an evening meeting with Brad Medford of Pacific (Taco) Bell to bring us up to speed on this new service that will be available next year.
While wet beam supplies have been the norm for UHF, it looks like the dry supplies are coming. Some of the supplies at Sutro will be switching power supplies capable of 35,000 volts. They'll mount in a standard rack. The advantage is that you can achieve really fine control of the voltage but then damp down quickly when an arc starts. Only prototype units are in the field presently and the supplies at Sutro should come from the first production run.
The new software is based around a computer functioning as a server that is looking at all your sites. Users are networked to the server.
Screens can be constructed with meters, pushbuttons, LEDs, spreadsheets, and text boxes. Moving elements around and sizing them is still a bit crude but there is an alignment feature. Still needed is the ability to specify spacing of elements and to draw lines between text boxes for diagrams.
I really like the spreadsheet feature. I have four amplifiers that each have 9 identical alarm functions. With the spreadsheet I was able to list the alarms in a vertical column and list the amplifiers across a horizontal header row. The spreadsheet intersections contain the channel status messages.
All of the site and channel information is entered into a MS Access database that is linked to the program.
If a network sends out surround sound sometimes and AC3 others, there isn't a simple way to detect the difference and adjust the audio/video rubber band to set sound sync.
A Dolby AC3 encoder will recognize surround sound but it must be set in the appropriate mode to do so. There is no standard for "lightly" compressed video.
