PBS Satellite Service or "HD01" (formerly PBS Schedule X in Eastern Time, with the west coast delay signal designated PBS-XD) is the 24-hour network feed from the Public Broadcasting Service (PBS) that provides a mixed variety of programming selected from PBS's regular network service. In the X/XD years was multicast by some PBS member stations on an over-the-air DTV subchannel along with their regular programming, or during overnight hours on their main channel to provide a second opportunity for viewers to watch or record primetime programming.
As of November 16, 2009, PBS-X can be received unscrambled via satellite on these coordinates:
- On SES Americom AMC-4 (at 101°W), on C-band transponder 16 (4020 MHz, horizontal polarity, in analog), since the 2006-05-31 switch from satellite Galaxy 26 (IA6) (at 93°W)
- PBS-HD01 on the AMC-21 satellite (at 125°W), on: Ku-band transponder 22 (12140 MHz, vertical polarity, DVB AC3-only), unencrypted.
- The defunct PBS-X (east/west, with the western feed tagged "XD") and other secondary PBS services (such as PBS You and PBS Kids (in standard definition) are or had been also on the AMC-21 satellite as Ku-band transponder 24 (12180 MHz, vertical polarity, DVB AC3-only), unencrypted.
Current satellite and transponder listings are available from LyngSat [1] and other online sources. Note that access to the Ku-band DVB feeds require AC3 (Dolby Digital) audio capability, as there is no MPEG2 audio provided on these transponders. Support for this format varies between FTA receivers and some may require external apparatus to convert this Dolby Digital audio to standard analogue.
Scheduling[edit]
PBS-X was freely and nationally available from AMC-21 at 125°W using free-to-air satellite dishes as small as three feet, and is also offered by U.S. direct broadcast satellite providers to subscribers who lack a local PBS feed.
PBS-X provided two free national feeds in each format, one scheduled for the Eastern U.S., the other, PBS-XD, on a three-hour delay to fit timezone differences for the West Coast. These services have been succeeded by the 1080i high-definition digital feeds PBS HD01 and HD02.
