Published by CONSUMER ELECTRONICS ASSOCIATION 2013 Technology http:/www.fcc.gov/wtb/rules.html 3 Definitions 3.1 Standard Frequencies (STD) This is a cable channel identification plan that uses standard off-air frequencies for the channels 2-6 and 7-13. Supplemental channels
9、 are 6 MHz increments down from channel 7 to 91.25 MHz and up from channel 13. Channels in the UHF band (470 MHz and above) are offset 2 MHz from the off-air allocations, and utilize different numeric designations. 3.2 Harmonic Related Carriers (HRC) This is a cable channel identification plan that
10、uses picture carrier frequencies that are multiples of 6.0003 MHz and starts at 54.0027 MHz. It involves the frequency displacements of approximately -1.25 MHz on all standard and supplemental channels except channels 5 and 6, where the displacement is approximately + 0.75 MHz. 3.3 Incremental Relat
11、ed Carriers (IRC) This is a cable channel identification plan that uses picture carrier frequencies starting at 55.2625 MHz and increments each channel by 6 MHz, except as noted. 4 Channel Identification Plan See Table 1 for the cable channel identification plan. 4.1 FM Band Usage Compliance with th
12、e channel identification plan does not require inclusion of channels 95-97. Utilization of these channels by a cable system is on a voluntary basis. 4.2 Channel Definition Regardless of the plan being used, or the type of signal (analog or digital), the channel edges are defined CEA-542-D 2 in Table
13、 1. The lower edge is 1.25 MHz below the nominal location of the NTSC visual carrier, and the upper edge is 4.75 MHz above the nominal location of the NTSC visual carrier. For signals delivered using Quadrature Amplitude Modulation (QAM), the (suppressed) carrier is 3 MHz above the lower channel edg
14、e. For signals delivered using 8-level or 16-level Vestigial SideBand (VSB) modulation, the (suppressed) carrier is 0.31 MHz above the lower channel edge. 4.3 Formula for Channels above Channel 158 Above channel 158, each 6 MHz channel shall be numbered consecutively, beginning with channel 159. 4.4
15、 Frequency Tolerances Frequency tolerances shall always conform to applicable FCC Rules. 4.5 Offsets Frequency offsets in the aeronautical bands are mandated by the FCC (47CFR 76.612). These offsets affect analog picture carrier frequencies, but do not affect the defined channel edges. In both stand
16、ard and IRC assignments, a single positive frequency offset is shown in Table 1. Applicable FCC rules permit other offsets. This standard recommends the offset shown in Table 1, absent reason to do otherwise. 4.6 Mixing of Channel Identification Plans Digital channels shall be carried using the same
17、 plan (standard, IRC or HRC) as is used for analog channels. 4.7 Non-Channelization Information that is not intended to be received by a subscribers TV is not required to conform to this standard; however, it is strongly recommended that the channel boundaries in Table 1 be utilized to the maximum e
18、xtent practical.
