Method of terrestrially transmitting digital signals

The invention claims a recommended a method for at least the digital signal transmission, especially digital broadcast and/or method of digital television signal broadcast. With the method, a decoding and data quantity, further - comprising at least or the digital signals to the OFDM method, and converting to at least one groove (31) frequency of the reflection, wherein the frequency of. The channel (31) is used to transmit the analogue television signal and is taken or the taken channel at least one (30,32) are. In addition, the flowing each time at least the digital signal spectrum (41) multiplier and vibration amplitude to a preset value; the value obviously is less than the analogue television signal broadcast spectrum (35,36) pix carrier multiplier or the vibration amplitude. Thus, only measurement at intermodulationing and crossed modulation with the digital signal or with an used signals at least one channel. At least the digital signal spectrum (41) (45) and transmission at least adjacent channel (30,32) and distance separatedly. When the groove (31) mile transmitting a digital signal, at least two pair of digital signals' frequency ranges (50) are arranged to send a protection frequency distance are.
