Appendix A Channel Allocation

The channel allocation shown here conforms to the requirements of CEA/ANSI 542-B, which specifies the correspondence between channel number and frequency for North America. This standard was developed by the joint EIA (now CEA)/NCTA engineering committee, and the original version has been adopted by the FCC as the standard for channel allocations in the United States. (As of this writing the FCC Rules refer to the standard by its old working designation, IS-6.) Picture carrier frequencies are shown, even for QAM signals, which have but do not transmit, a carrier. The channel extends from 1.25 MHz below the analog picture carrier, to 4.75 MHz above. For QAM signals, the carrier is in the center of the channel. For 8-VSB signals, the carrier is 310 kHz above the low band edge. For all digital modulation, there is a single carrier, not separate carriers for picture and sound. Three channelization plans are shown. They are explained in section 9.2.
