Embodiment Construction

[0015] please see figure 1 , the terminal 100 capable of receiving data broadcast signals includes an application program 102 and a data tube wave signal receiving unit 104 . For the processing method of the data tube wave signal in the terminal 100, please refer to figure 2 . First receive a command from the application program 202 in step 202, the command is to receive any one of the command to select the band, select the channel, open the data broadcast signal receiving unit, close the data broadcast signal receiving unit and search for the next channel. Receive the data broadcasting signal of a channel in step 204 according to the command received and carry out standard verification, then judge in step 206 whether the received data broadcasting signal is compatible with the standard verification, if corresponding then enter step 208 and carry out standard verification After checking, the data broadcast signal is transmitted to the application program, and if it does not ...

Abstract

The invention relates to a method for processing data broadcasting signals, which is used for processing the data broadcasting signals received by a data broadcasting signal receiving unit and a receiving terminal of an application program. The method comprises the following steps: (1) receiving a command of the application program; (2) controlling the data broadcasting signal receiving unit to receive channel data and perform standard verification on the channel data according to the command of the application program; (3) judging whether the channel data corresponds to the standard verification or not; and (4) transmitting the channel data to the application program if the channel data corresponds to the standard verification, or discarding the channel data if the channel data does not correspond to the standard verification. The method transmits the received channel data to the application program only after standard verification of the channel data, can check the correctness of the data broadcasting signals and find out incorrect information in time, and can avoid the transmission of the incorrect information to the application program.

Description

technical field [0001] The present invention relates to a data broadcast signal, in particular to a method for processing the data broadcast signal in a terminal receiving the data broadcast signal. Background technique [0002] The Data Broadcasting System (RDS) is a European specification for data broadcasting systems formulated by the European Broadcasting Union (EBU) in 1984. The main feature of data broadcasting is to use the existing FM broadcasting resources to realize it by inserting digital codes into the broadcasting signal. It is separate from the audio signal and does not interfere with reception or affect radio sound quality. When the radio detects and demodulates these digital codes, it can provide the corresponding functions. The loaded data content can include radio station type, program type, traffic announcement, advertisement information, standard time, weather forecast, etc. At the same time, an open data interface is provided to provide data and text a...
