PAL/SECAM Cable Television Channels and Relative Frequencies

Table C-7provides information on the Phase Alternating Line (PAL) and SEquential Couleur Avec Memoire (SECAM) frequency map for standard 7and 8 MHz channel bands in Europe.

The FCS (reference subcarrier frequency) for color integration is different for different countries. As well, the channel/frequency designations is different for different countries. For a summary of the ITU designations for PAL/SECAM systems and Recommendation ITU-R BT.470.6 standards, refer to Table C-1, Table C-2, and Table C-3 . These tables provide general information that may help determine frequency allocations for specific countries. Table C-7is a frequency allocation table for PAL B and G locations. Also note that some countries use different schemes for VHF and UHF. Table C-8is a frequency allocation table for PAL D and K locations for the People’s Republic of China.

More information can be found at the Web sites listed on page E-1.

Note The downstream frequency plan will include all center frequencies between 112 and 858 MHz on 250 kHz increments. It is up to the operator to decide which frequencies to use to meet national and network requirements
