Abstract

PURPOSE: A method and a device for storing and searching data are provided to sequentially input information received in MP3(MPEG(Moving Picture Experts Group) layer 3) broadcasting according to specific information, such as time, frequency and genre in a memory, and to search necessary information using the specific information. CONSTITUTION: Information including frequency, reservation time, target memory medium and tag information, for sequentially storing data received through an RF(Radio Frequency) part in a corresponding memory, is inputted through an input part(41). Whether the data received through the RF part corresponds to the inputted information is decided(42). If so, the data are classified according to types by the information of the received data to be sequentially stored in a corresponding memory card of a plurality of memory cards. If the capacity of the corresponding memory card is short, the data are sequentially stored in a spare memory card(43). When searching data stored in the plurality of memory cards, search is performed according to information inputted in the step 41, and searched data are decoded in a decoder and amplified in an amplifier then outputted through a speaker(44,45,46).

When the frequency setting of the reserved broadcasting station, the current progress time, the reserved broadcasting time set and the recording mode for recording the cassette set 3 are input from the key input unit 5 connected to the microprocessor 6, the microprocessor 6 After storing the information in RAM 6A and displaying the set information through the display unit 7, it detects whether the current time coincides with the reserved broadcast time and returns if it does not match, but the current time coincides with the reserved broadcast time. Then select the PLL ICs (1A, 1B) of the tuner stage 1 that you want to reserve and then detect if you want to record and connect the selected PLL IC to the output amplifier 4 through the switching unit 2 if you do not want to record. If you want to record, switch the switches in the switching unit 2 so that the PLL IC 1 of the scheduled broadcast is connected to the output amplifier 4, and the PLL IC of the broadcast that you want to record is connected to the cassette deck 3. One , The process that drives the 8 to the cassette deck will be driving on the scheduled broadcasts and recordings from an audio receiver.

However, in the conventional FM radio broadcast, since there is no additional data added to the received signal, it was not possible to store and / or search by certain specific information (singer, genre, title, etc.). (Frequency selection, time selection, etc.) were separately operated to store the received data in a memory medium such as a target tape or a target memory.

The present invention improves the operation of the conventional system as described above, and proposes an apparatus and method for storing / retrieving the received data in the MP3 broadcast in each memory medium using specific information.

It is also proposed to allow the microcomputer to automatically perform the above storage / retrieval based on the information already entered.

In the present invention, the reception information is characterized in that it comprises at least one or more broadcast frequency, broadcast time, target memory for storing data, tag information of the data.

Also, in the present invention, the tag information of the data includes at least one of title, artist, album, year, genre, and the like. Each can be stored and / or searched by type.

In addition, the present invention is characterized in that when storing the received data when the corresponding memory is insufficient to store sequentially in the extra memory.

Other objects and features of the present invention will become apparent from the detailed description of the embodiments with reference to the accompanying drawings.

Hereinafter, an apparatus and method for data storage and retrieval according to the present invention will be described with reference to the accompanying drawings.

2 is a block diagram for storing and retrieving received data.

As shown in the figure, an input unit 10 for inputting information (frequency, reservation time, target memory medium, Tag information) in order to store received data separately by type; A memory 20 in which the information is stored; A song information separator (80) for separating the data received by the receiver (60) by the information stored in the memory (20); A memory unit 70 having one or more memory media for storing the received data according to the information of the memory 20; A decoder unit 90 for decoding the information output from the separation unit 80; A curved tack unit (50) for searching data stored in the memory (70); The control unit 30 is connected to the respective parts to control the system, and the information output from the decoder 90 is amplified by the amplifier 100 is output through the speaker 110.

The power supply 40 is operated by the control of the microcomputer 30 after the microcomputer grasps the on / off state of the power supply at the reserved time of the received data.

More specifically, referring to FIG. 2, in order to sequentially store MP3 broadcast data received through the RF unit 60 in the plurality of memory cards 70, the user may input a frequency, a reservation time, A target storage medium (memory, CD, card, etc.), tag information, and the like are input, and the input information is stored in the memory 20.
