 | | Synchronizing pulses at precise time intervals are inserted in these periods to ensure correct scanning in the receiver. |
| | For terrestrial broadcasting the complete vision signal modulates a radio wave in one of the ultra-high-frequency (UHF) bands between 470 and 890 mHz as a carrier, while the corresponding sound (audio) signal has its own carrier at a slightly higher frequency. |
| | High-definition TV systems with more than 1000 scanning lines will be transmitted via satellite using the super-high-frequency (SHF) band, 11.7 to 12.5 gHz. |
