FAQ: Digital Television

Channel 7 then moved its digital signal from UHF Channel 24 to VHF channel 7 at 24kw ERP. (You may not have known this because your converter box simply displayed "7.1.")

Some viewers who received us on UHF channel 24 are not receiving us now.

Please try these steps first:

Now through the first of October, Sutro Tower will be removing the analog antennas and installing the digital antennas on top of the tower.

As of Thursday, June 18th at 8 a.m., KGO is transmitting from our auxiliary antenna, several feet below the top of the tower. Viewer reception will vary while we are broadcasting from our auxiliary antenna and replacing our main antenna. This work is expected to take 4 weeks, approximately through mid-July. We expect indoor antenna reception to improve with our new main antenna, although reception will vary until all tower work is completed in October 2009.

Evening reception will be normal after mid-July, but will vary when we broadcast from our auxillary antenna 7 a.m. - 5 p.m. Monday through Saturday on days when crews are working on the top of the tower to replace the other 2 large antennas serving other stations.

Due to construction delays the completion of the Sutro Antenna project is expected to be the end of October, 2009.

We apologize for the inconvenience. We appreciate your patience as we work through this antenna transition.

On June 12, 2009, full-power analog broadcasters will transition to digital television service. If you receive free over-the-air TV from an antenna and you do not have a digital TV set, you will need a converter box that converts the digital signal into the analog format in order to continue to receive access to free digital television after the transition date. If you subscribe to satellite, cable, or a paid TV service, or if your TV has a built in digital tuner, no action is necessary.

For additional information regarding the analog to digital transition and to receive a $40 coupon (2 per family) towards a converter box, please visit www.dtv2009.gov or call 1-800-DTV2009; for the hearing impaired call 1-877-530-2634.

What is analog television?
Analog television service is the traditional method of transmitting television signals. Analog transmission has been the standard broadcast technology since the inception of television. Analog is not as efficient as digital television: it uses up much more of the valuable spectrum than digital, and TV stations can only transmit one channel of programming with an analog signal versus up to four or more programs with a digital signal in the same amount of spectrum. Analog is also susceptible to interference and "snow" that make a picture less clear.

What is the DTV transition?
The DTV transition is the switchover from analog (the traditional method of transmitting television signals) to exclusively digital broadcasting of free television programming for all full-power television stations. The transition from analog to digital television represents the most significant advancement of television technology since color TV was introduced. The DTV transition will be completed on June 12, 2009, as set by Congress. Full-power television stations have been preparing for the transition from analog to DTV since the late 1990s, when they began building digital facilities and airing digital channels alongside regular analog broadcasts. Today, 1,624 out of 1,762 full power television stations nationwide offer digital programming.

What equipment do I need?
If you currently receive free over-the-air television programming on an analog television set, you will need a DTV converter box to continue to receive television service after June 12, 2009. DTV converter boxes will be available in early 2008. To help consumers cover the cost of the converter box, the National Telecommunications and Information Administration (NTIA) is issuing up to two converter box coupons valued at $40 each to households. Information about the DTV converter box coupon program is available at www.ntia.doc.gov.

How do I know if I have an analog or digital television set?
To check whether your TV set can receive over-the-air digital broadcast signals, review your owner's manual or examine the set to see if it has a built-in Advanced Television Systems Committee (ATSC) tuner. You can also visit the manufacturer's Web site and find out the capabilities of the set using the manufacturer model number.

Will I need a special antenna to receive DTV over the air?
If you currently use an indoor or rooftop antenna to receive over-the-air analog broadcast television signals and you already get good or excellent reception quality, you should be able to get reception of digital television broadcast signals with the same antenna. For more information about using an antenna to receive local television broadcast channels, visit www.antennaweb.org.

Can I continue using my existing VCR with a DTV converter box for timed recordings?
Yes. However, after the digital transition, the tuner in the VCR won't be able to pick up over-the-air programs for recording. Instead, the input to the VCR must be connected to the output of the DTV converter box. You must set the tuner in the DTV converter box to the channel you want to record prior to the start of each recording period programmed in the VCR.
