Claims (2)

1. Способ контроля качества цифрового радиовещания в средневолновом и коротковолновом диапазонах, отличающийся тем, что в целевом диапазоне или рядом с ним находится, по меньшей мере, одна приемная станция, с помощью которой оценивают данные качества принимаемого высокочастотного цифрового сигнала и определяют соответствующие значения параметров, полученные значения параметров передают в радиопередатчик, причем передачу в радиопередатчик полученных значений параметров осуществляют автоматически и через Интернет, при этом передаваемые в радиопередатчик значения параметров используют для воздействия на количество степеней модуляции и/или кодирования передачи или для определения альтернативных передающих частот.1. A method for monitoring the quality of digital broadcasting in the medium and short wavelength ranges, characterized in that at least one receiving station is located in or near the target range, with which the quality data of the received high-frequency digital signal is evaluated and the corresponding parameter values are determined, the obtained parameter values are transmitted to the radio transmitter, and the transmission of the obtained parameter values to the radio transmitter is carried out automatically and via the Internet, while s in the transmitter parameter values are used to influence the number of degrees of modulation and / or coding transmission or to determine alternative transmission frequencies. 2. Способ по п.1, отличающийся тем, что значения параметров, полученные приемной станцией в целевом диапазоне и переданные в радиопередатчик, сохраняют в базе данных для прогнозирования частот.2. The method according to claim 1, characterized in that the parameter values obtained by the receiving station in the target range and transmitted to the radio transmitter are stored in a database for frequency prediction.
