DIGITAL AND/OR ANALOGIC TELEVISION CARRIER SIGNALS AND DEVICE FOR MEASURING AND PROCESSING DIGITAL AND/OR ANALOGIC TELEVISION CARRIER SIGNALS

摘要

The system automatically identifies, in the channel that the device is tuning, whether a carrier of digital or analogical television is being transmitted with the steps of tuning (2) the frequency calculation (3) of the level measured at said frequency comparison (4) of the level with preset minimum values variation (6) of the frequency calculation (7) of the level measured to said frequency comparison (8) of the average result obtained at the original frequency, identification (10) of the signal as a digital or analogical carrier depending upon whether the obtained result is similar to or different from the level measured at the original frequency. The device carries out certain automatic tunes to determine whether the carrier is digital or analogical and includes an output unit (12) that outputs the result of the identification.
