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 ANT 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 111 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.

In the high-definition radio receiver shown in FIG. 2, when the store and replay buttons are pressed while listening to radio broadcast, the corresponding digital audio program content is stored in a memory inside the radio receiver. High-definition radio receivers, on the other hand, have a built-in file system and decoder.

FIG. 3 is a flowchart illustrating a method of driving the radio receiver shown in FIG.

As shown in FIG. 3, when the storage button is first pressed (S1), the data stream output from the digital processor 114 enters the file system at the time when a storage request is received from the host controller. S2). The file system checks the state of the memory device, sets the file name by combining time / date information, and allocates new space inside the memory device. The stream output from the digital processor 114 is recorded in the newly allocated memory area until the stop command is input (S3, S4). Subsequently, when the stop command is input, the stored file information is output as a message (S5). This message includes the file name and size.

When the radio receiver operates as shown in FIG. 3, if the radio receiver is stored at a weak electric field point (received sensitivity decrease), the defective stream is stored as it is. When replayed later, it can only be reproduced in a defective state.

In the case of a stream of a normal radio broadcast, the same stream is not likely to be broadcast, but in the case of a song, the same stream may be broadcast, so that the quality of the stored file is compared and stored again as a stream having a lower defect quality. Can improve. The function of restoring can be extended even when the same information such as oil price and weather by gas station is continuously updated and transmitted.

The present invention proposes a method of driving a high definition radio receiver capable of storing a stream of better quality when a stream of higher quality is broadcasted later.

The driving method of the high-definition radio receiver according to the present invention analyzes the error degree for each stream type and restores the stream when the stored stream is re-broadcasted. Restoration techniques can improve sound quality for songs and correct false information for data streams. Thus, the user can save the cleanest stream to improve sound quality and automatically correct error information.

The file system S12 checks whether the stream type is a data stream, a song or a predetermined type (S13). In the case of the data stream, the file name is set by combining time / date information, and the state of the memory device is checked. Find the file point by checking whether there is the corresponding information in the previously stored file list, and if not, a new area is allocated (S17). It is checked whether the error rate of the current stream is smaller than the stored error rate (S18). Subsequently, the stream output from the digital processor 114 is recorded in the newly allocated memory area before the stop command is input (S14). Subsequently, when a stop command is input (S15), the stored file information is output as a message (S16).

If it is not of a predetermined type, a new area is allocated (S14). It is checked whether the error rate of the current stream is smaller than the stored error rate (S18). Subsequently, the stream output from the digital processor 114 is recorded in the newly allocated memory area before the stop command is input (S14). Subsequently, when a stop command is input (S15), the stored file information is output as a message (S16). This message includes the file name and size, and information about whether the file was restored or was originally saved.

As described above, when the radio receiver is driven, the user can effectively store a better quality broadcast if the broadcast is re-broadcasted even if the previously stored contents of the radio broadcast from the radio are defective.
