Mon 8/01: DT9 Over the Air PSIP outage (apx 8:30am-2:30pm)

August 1, 2016 · Filed Under KQED · Comments Off on Mon 8/01: DT9 Over the Air PSIP outage (apx 8:30am-2:30pm) 

RESOLVED: PSIP was restored at apx 2:30pm Monday. Our signal should be ID’g as 9-1, 9-2 & 9-3 again.

(DT9-1, 9-2 & 9-3)

BACKGROUND: the PSIP information line in our Over the Air signal stopped again this morning. So while we were still transmitting programming on our three channels, they were showing up as 30-1, 30-2, 30-3, rather than 9-1, 9-2, 9-3, until the signal was repaired again. Viewers can determine if this is a station issue by punching in channel “30”, and seeing if they find us there. However, the onscreen guide info will not be available until PSIP is restored, and the channel reverts to identifying itself as “9”.

Additional info for the curious: since the digital conversion several years ago, very few stations actually transmit on the old frequency that the channel number identified. The FCC didn’t want viewers to have to learn new numbers for all their local TV stations, so even tho TV stations now transmit on different frequencies from their analog days, a “Virtual ID” is sent as part of the PSIP info, which tricks your TV into labeling the new frequency with the old number. So, with our virtual ID currently not working, our signal is currently labeled with our Real Frequency (RF) number, which is 30.

And what does “PSIP” stand for? Program and System Information Protocol (the data line that includes the program guide info and the virtual ID for changing “30” into “9” as our channel number).

Mon 6/27: DT9 PSIP issue for Over the Air viewers

June 27, 2016 · Filed Under KQED · Comments Off on Mon 6/27: DT9 PSIP issue for Over the Air viewers 

RESOLVED: PSIP was restored at apx 2:50pm Monday. Our signal should be ID’g as 9.1, 9.2 & 9.3 again.

Our Over the Air (OTA) signal for DT9 is still transmitting. However, we are aware that the PSIP information line in our OTA signal has stopped. Engineers are working to resolve the issue.

In the meantime, OTA viewers may be able to find the three channels at 30.1, 30.2 & 30.3 until the issue is fixed. However, the onscreen guide info will not be available until PSIP is restored, and the channel reverts to identifying itself as “9”.

7/07: Transmitter status / 2 other tech issues

July 7, 2011 · Filed Under KQED Plus, KQET · Comment 

KQED-DT9 (San Francisco)
Fiber feeds to Comcast Cable, Astound Cable and AT&T U-verse normal. Over-the-Air (OTA) transmissions normal, operating at 98-100% power. 100% power = 710 kW.

KQED Plus-DT54 (San Jose)
Fiber feeds to Comcast Cable, DirecTV and Dish Network normal. OTA transmissions normal, operating at 98-100% power. 100% power = 290 kW.

KQET-DT25 (Watsonville/Monterey)
Fiber feeds to Comcast Cable normal. OTA transmissions normal, operating at 98-100% power. 100% power = 81 kW.

Two technical issues not related to transmitters:
The programming schedule for KQED v-me (Comcast 191/621, DT54.5, DT25.3) is currently 3 hours earlier than “normal”, as we are passing the satellite feed straight through, rather than delaying it for 3 hours. The delay box is out for repairs. We expect to stay on this “early” schedule for at least another 7-10 days, possibly longer.
The Over the Air DT54.# onscreen guide for all our DT54 channels is currently 1 hour off. It is also occasionally not reading information for its various channels, and instead posting a generic “DTV Program” message. A piece of equipment for this function is also out for repair. We anticipate this problem lasting through most of July, possibly longer.
Updates on both issues will be posted here as new information becomes available.
