After the i-Pod is connected to the high quality radio, the token information is converted to XML format and transmitted to the i-Pod.

Fig. 2 is an internal block diagram of a high quality radio for explaining the present invention, and is for explaining the operation of the high quality radio.

As shown in FIG. 2, the high quality radio 1000 includes an antenna ANT, a core unit 100, a main memory unit 200, and a host controller 300.

The antenna ANT is for receiving a high quality radio broadcast provided wirelessly. The core unit 100 is a block for processing a radio broadcast provided by the antenna 100 so that a user can listen through a speaker.

The main memory unit 200 is a block for storing data or programs necessary for the operation of the high quality radio 1000.

The host controller 300 controls the main memory unit 200 and the core unit 100 to perform a predetermined operation, and transfers data provided from the core unit 100 to a computer PC, or provides the computer PC. Receive data and store it in the intended place. The host controller 300 and the computer PC transmit and receive data through the USB interface.

The core unit 100 includes a transfer unit 110, a radio core unit 120, a reset block 130, a program memory unit 140, and a 40M crystal 150. The transmitter 110 transmits a signal provided from the antenna ANT to the radio core unit 120. The reset block 130 controls the reset operation of the radio core unit 120. The program memory unit 140 stores a program for operating in the radio core unit 120 and may be implemented as a flash memory. In addition, when free space is generated due to the capacity of a program stored in the program memory unit 140, other data may be stored.

The radio core unit 120 includes an analog processor 111, an ADC 112, a digital tuner 113, a data memory unit 116, a digital processor 114, and a digital interface 115. The analog processor 11 performs a predetermined analog operation by using the signal provided through the transmitter 110 and transmits it to the ADC 112. The ADC 112 converts the input analog value into digital and outputs it. The digital tuner 113 processes the digital value output from the ADC 112 and provides a broadcast signal of a channel selected by the user.

The digital processor 114 controls the digital tuner 113, the data memory unit 116, and the digital interface 115 using a program stored in the program memory unit 140. The digital interface 115 transfers data provided from the digital processor 114 to the host controller 300. The data memory unit 116 stores data transferred from the digital processor 114.

The high quality radio receiver shown in FIG. 2 is stored by pressing the save button provided when the user wants to store the song while listening to the song. However, when the user presses the save button, only a part of the song is stored since the song has already flowed substantially.

In order to solve this problem, the present invention provides a method of driving a high quality radio receiver having a function of storing a user's desired song more effectively.

In the case of high-quality radio broadcasting, the radio broadcasting includes additional data such as song titles, artists, album information, and the like. Such data is called program service data (PSD). According to the present invention, the PSD data is downloaded in advance and midnight, and when matched with the PSD data output to the radio broadcast, the corresponding radio broadcast is automatically stored in the memory of the radio receiver.

As shown in FIG. 3, the method of driving a high quality radio receiver first downloads a tag of a song to be stored through the Internet (S1). Here, the tag includes PSD information. Next, clean up the downloaded tags. In this case, it is referred to as file management (S2). Subsequently, when PSD data included in the received radio broadcast is changed and input (S3), it is compared with already stored tag information (S4). Subsequently, if the compared information is different from the stored PSD information, the PSD is continuously checked (S4). If the same PSD as the stored tag is confirmed, the stream is stored in the memory device (S5). A stream is a radio broadcast that can be stored in response to a song or other PSD that is currently being broadcast. When the saving is completed, the message is transmitted and the stored tag is deleted (S6). Subsequently, a related message is output (S7).

The high quality radio receiver presented in this embodiment may receive data contained in the PSD in advance. For example, you can download the tag of the song you want to save through the music site, and then save the downloaded tag information on the radio receiver.

In the case of a song, the PSD of the broadcast flowing out of the broadcast is changed 10 seconds before the song is broadcast. Here, 10 seconds may vary depending on the broadcasting system. The PSD data according to the pre-stored tag information and the changed PSD data are compared and compared with the next changed PSD data. If the PSD data by pre-stored tag information and the changed PSD data are the same, the broadcasted song is stored in the internal memory of the radio receiver. All memory devices included in the radio receiver can be used for storage.

You can automatically delete the tag of a song that has been saved. In addition, although it can be left without deleting, in this case, the memory capacity of the radio receiver may decrease.

In addition, the radio receiver may be automatically driven to store the radio broadcast when the music to be stored is selected without storing the radio broadcast.

As described above, when the radio receiver is driven, the user can more effectively store a desired portion of the radio broadcast broadcast on the radio.
