Abstract

PURPOSE: A method for receiving a broadcasting in a broadcasting receiver is provided to quickly search a broadcasting station channel which broadcasts a program for a user wants. CONSTITUTION: It is judged whether a broadcasting recognition code about another broadcasting station is received(S30). If the broadcasting recognition code about the other broadcasting station is received, the same program code is searched from an arrangement map of memorized broadcasting stations(S32). If the same program code is searched, the searched program code is stored in a PHY(Program Type) map(S34). If the same program code does not exist, the received broadcasting recognition code is stored in a specific memory(S36).

Description

Broadcast receiving method of broadcast receiver

The present invention relates to a broadcast receiving method of a broadcast receiver, and more particularly, radio data providing a function (hereinafter referred to as 'EON' (Enhancel Other Network)) for providing information on a broadcast station other than the broadcast station currently being received. RDS (Radio Data System) The present invention relates to a broadcast receiving method of a broadcast receiver for quickly searching a broadcasting station channel for broadcasting a program desired by a user in a broadcasting network.

As shown in FIG. 1, the conventional broadcast receiver includes an intermediate frequency demodulator 20, an RDS demodulator 30, and a controller for processing an FM signal received by an FM reception tuner 10 as an intermediate frequency signal. 40).

In the broadcast receiver configured as described above, the RDS signal passing through the tuner unit 10 and the intermediate frequency demodulator 20 is supplied to the RDS demodulator 30 in a mixed form with a general audio signal.

The RDS demodulator 30 separates, amplifies and modulates the RDS signal mixed with the audio signal to make a clock necessary for RDS reception and extracts data.

In addition, the controller 40 receives the clock and data output from the RDS demodulator 30 and performs array management using information required by the receiver through error correction, synchronous decoding, and the like. Program name (PTY) information is also included in the data. Included.

On the other hand, the controller 40 has an electronic tuning method of controlling the tuner unit 10 using a phase locked loop PLL.

However, when the user selects the PTY mode and selects the desired program (PTYRQ), the conventional broadcast receiver operates as shown in the flowchart of FIG. 2 among the signals received from the tuner unit 10 to find a desired program. In order to search for a channel of a broadcasting station that broadcasts the same program as the desired program, the user selects a desired program and then continuously increases and decreases the frequency, thus searching for a broadcasting station channel.

Accordingly, an object of the present invention is to provide a broadcast receiving method of a broadcast receiver for quickly searching for a broadcasting station channel for broadcasting a program desired by a user.

The present invention to achieve the above object,

A radio data system receiver for car audio, comprising: a comparison step of comparing whether a program (PTYRS) of a broadcasting station currently received and a program (PTYRQ) selected by a user are the same;

A determination step of determining whether the same program as the program selected by the user exists in the memory map (PTY MAP) if the program selected by the user is different from the program currently being received by the comparison step;

When the program PTYRQ selected in the determination step is present in the memory map PTYMAP, a switching step of converting the selected program to a channel frequency of a broadcasting station broadcasting the selected program may be performed.

Hereinafter, the present invention will be described in more detail with reference to the illustrated drawings.

3 is a step S32 of searching for the same program code in the arrangement map of the memorized broadcast stations shown in FIG. 4 when it is determined whether the broadcast recognition code for the other broadcasting station has been received in step S30, and if the same program code is found. Step S34 is stored in the PTY map, and step S36 is stored in a separate memory (N + 1) when there is no same program code.

4 shows an arrangement up to the Nth of a broadcasting station identification code and a program name (PTY).

The program information stored as shown in FIGS. 3 and 4 is used as a reference in the program name search of FIG. 5, and the process is as follows.

When the user switches the mode to search for the desired program name, the controller determines this in step S51 and proceeds to step S53 to determine whether the program PTYRQ selected by the user and the program currently being received PTYRS are the same. In other cases, the process proceeds to the next step to find the same PTY as the RTYRQ received as shown in FIG. 3 and recorded on the PTY map shown in FIG.

If there is no identical PTY in step S55, the receiving operation is terminated, but other necessary operations are processed on another program. When the same PTY is found in step S55, the program is tuned to the broadcasting station (K-th broadcasting station) having the array PI of the corresponding memorized broadcasting stations as in step S57 to find a program desired by the user.

According to the present invention operating as described above, when a user selects a specific program when receiving a RDS (Radio Data System) broadcast having a function (EON) for providing information about a broadcasting station other than the currently receiving broadcast station. There is an advantage that you can find the relevant station quickly by using EON information.

Therefore, according to the present invention configured as described above when the user selects a specific program when receiving a RDS (Radio Data System) broadcast having a function (EON) for providing information about other broadcasting stations other than the currently receiving broadcast station Using the information, you can find the station quickly.
