Description

Music data processing method using KBPS

The present invention relates to an apparatus for receiving KBPS (Korea Broadcasting Program System) data, and more particularly, to a method of processing music data among KBPS data.

KBPS data is one of broadcast methods that allows additional program data, text multicasting, and the like by inserting additional additional data in a vertical blanking period of a broadcast video signal.

That is, the scanning method performed to form one screen using a cathode ray tube or the like is divided into sequential scanning and interlaced scanning, and a method generally performed is interlaced scanning.

Interlaced scanning starts from the upper left of the screen and sequentially scans the image signal to reach the bottom center of the screen. That is, interlaced scanning is called interlaced scanning because it is spaced by one line, and it is called interlaced scanning. Since the screen at the end of one vertical scanning is called 1 field, 1 screen is composed of 2 fields in interlaced scanning. do.

In this interlaced scan, the electron beam needs to return from the bottom to the top of the screen. This is called vertical retrace. In this vertical retrace period, substantially horizontal scanning is performed continuously. However, since this period is not required as an image, a blanking signal enters, and this period is called a vertical blanking interval.

It is known that the vertical blanking period is composed of 21 horizontal scanning periods so that information such as text data can be duplicated at the appropriate position. KBPS refers to a Korean character multicasting format in which reservation recording and separate character information are transmitted in such a vertical blanking period, and the reservation recording and character display are performed according to the KBPS data. .

Using this KBPS data, it is possible to transmit and receive a variety of information, but none of the proposed methods to transmit and receive data about music until now. In other words, viewers who are watching music broadcasts are generally interested in the kinds of music broadcasted, singers, lyrics, and popularity rankings, and are known to have a strong tendency to confirm such information. No method for the effective use of is proposed.

In order to solve this problem, the present inventor has proposed a method for processing KBPS music data, which makes it possible to effectively store and use KBPS data about music transmitted from a broadcasting station.

In this method, the inventor constructs a data table, and the decoder divides KBPS data into music type, singer, popularity rank, and other kinds of information, and writes an address in memory to these tables so that the decoder needs information (i.e., music). When reading (by type, singer, popularity ranking, and other types), the contents of the data table can be referred to, thereby reducing the reading time of necessary information.

However, in general, the capacity of the memory for storing KBPS data is limited, and since the KBPS music data transmitted from broadcasting stations cannot be stored indefinitely in the memory, a separate storage device is required.

SUMMARY OF THE INVENTION The present invention has been made in view of this point, and an object of the present invention is to provide a method for processing KBPS music data, which makes it possible to selectively store KBPS music data on a magnetic tape, thereby storing a large amount of KBPS music data. .

KBPS music daytag processing method according to the present invention comprises the steps of determining whether the KBPS music data confirmation mode is set; Displaying the type of stored KBPS music data when the KBPS music data checking mode is set; Determining whether one of the displayed KBPS music data types is selected; Displaying information corresponding to the selected KBPS music data data type; Determining whether a recording mode is set while displaying information corresponding to the selected KBPS music data data type;

When the recording mode is set, recording the selected KBPS music data and recording them on a magnetic tape.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

First, in order for the apparatus according to the present invention to perform a function, the broadcasting station must transmit the music data as described above as KBPS data. That is, the broadcasting station should transmit KBPS data about the type, singer, popularity ranking, and other kinds of music being broadcasted as KBPS music data.

1 is a block diagram of an apparatus for carrying out the present invention for receiving and processing KBPS music data transmitted from a broadcasting station.

As shown in the drawing, the tuner 1, the microcomputer 2, the decoder circuit 10 and the switch 3, the signal processing circuit 4, the OSD unit 5 and the deck 6 are It is preferable to use a video cassette recorder (hereinafter referred to as a VCR) provided.

In this configuration, the tuner 1 receives a broadcast signal of a predetermined channel under the control of the microcomputer 2, and the signal received by the tuner 1 is applied to the switch 3 and the decoder circuit 10, respectively.

In this case, the decoder circuit 10 may include the synchronization separator 11, the data separator 12, the decoder 13, the data table 14, the memo unit 15, and the digital / analog converter ( 16). That is, the sync separator 11 separates the sync signal from the received broadcast signal of the tuner 1 and applies the sync signal to the decoder 13, and the data separator 12 separates the sync signal from the sync signal separated by the sync separator 11. KBPS data are separated and applied to the decoder 13.

The decoder 13 stores KBPS music data applied from the data separator 12 in synchronization with the synchronization signal, that is, information on the type, singer, popularity ranking, and other types of music, respectively, at predetermined addresses of the memory 15. Then, the information about the address in this memory 15 is recorded in the data table 14 shown in FIG. In other words, the decoder 13 divides the KBPS data into music types, singers, popularity rankings, and other types of information, and writes addresses in the memory 15 in these tables. Therefore, when the decoder 13 reads out necessary information (that is, by music type, singer, popularity ranking, and other types), the contents of the data table 14 can be referred to, thereby reducing the reading time of the necessary information. It will be readily apparent to those skilled in the art.

On the other hand, the decoder 13 outputs KBPS music data stored in the memory 15 as a predetermined text signal (in a digital state) under the control of the microcomputer 2, and the digital / analog converter 16 The text signal is converted into an analog state and applied to the switch 3.

The switch 3 selectively applies a signal of the tuner 1 or the digital / analog converter 16 to the signal processor 4 and the recording processor 7 under the control of the microcomputer 2, and the signal processor ( 4) processes and outputs the signal of the digital / analog converter 16 in a state capable of displaying the cathode ray tube or the like. The signal processed by the signal processing unit 4 is applied to the OSD unit 5, and the OSD unit 5 mixes a predetermined OSD character under the control of the microcomputer 2 with the signal of the signal processing unit 4, and then mixes the mixed signal. Is applied to a cathode ray tube or the like.

In addition, the recording processing unit 7 writes the signal of the digital / analog conversion unit 16 to the magnetic tape under the control of the microcomputer 2 and applies it to the deck 8 so that the deck 8 can be recorded. Is configured to record the signal of the recording processing unit 7 on the magnetic tape under the control of the microcomputer 2.

As described above, the microcomputer 2 controls the driving of the apparatus of the present invention as a whole, and this control can be selected by the user using the key of the key matrix 6. That is, the key matrix 6 is configured with various function keys for controlling the operation of the apparatus of the present invention, and the microcomputer 2 searches for the pressed keys among these keys to correspond to the pressed function keys as described below. It is configured to control the driving of the device.

3 shows a flow chart for the microcomputer 2 to carry out the method according to the invention.

As shown, the microcomputer 2 of the present invention determines in step 31 whether a predetermined music information key for pressing the output of KBPS data stored in the memory 16 has been pressed.

If the music information key is pressed as a result of the determination in step 31, the microcomputer 2 proceeds to step 32 and causes the OSD unit 5 to select the type of KBPS music data, that is, the type of music, the singer, the popularity ranking, and the like. Outputs an OSD signal ordering one of the selections. That is, the microcomputer 2 is the key type of the key matrix 6 necessary for selecting one of the type of music, singer, popularity rank and other types as shown in FIG. 4 (in this embodiment, the keys for selecting them). Are set to 1, 2, 3, and 4 numeric keys, respectively).

In addition, the microcomputer 2 performs the steps 33-37, and the predetermined time (30 seconds in the present embodiment, but this time can be added or subtracted as needed, it is easy for those skilled in the art of the present invention. Will determine if one of these 1,2,3,4 keys has been pressed.

As a result of the judgment of steps 33-37, if no key is pressed within 30 seconds, the microcomputer 2 proceeds to step 38 and continuously displays the signal received by the tuner 1 on the monitor, If any key is pressed, the decoder 13 causes the data table 14 area corresponding to the key (i.e., the area storing the memory 15 address by music type, singer, popularity ranking, and other types). The KBPS music data in the memory 15 stored at My Address is read out (steps 39, 40, 42).

In this way, the KBPS data of the memory 15 read by the decoder 13 is applied to the switch 3 converted into an analog signal by the digital / analog converter 16, and the microcomputer 2 performs step 43 By controlling the switch 3 to output the signal of the digital / analog converter 16, KBPS music data is displayed on the monitor.

Then, the microcomputer 2 proceeds to step 43 to determine whether a predetermined recording key is pressed among the keys of the key matrix 6, and when the recording key is pressed, the process proceeds to step 44. In step 44, the microcomputer 2 drives the recording processing system 7 and the deck 8 so that the KBPS music data being displayed on the monitor (type of selected music, singer, popularity ranking and other as described above) Type) on a magnetic tape.

At this time, the microcomputer 2 reads out all the KBPS music data from the memory 15 only when the decoder 13 designates all addresses in the memory 15 of the data table 14 area corresponding to the pressed key. When the KBPS music data is read out, the recording processing system 7 and the deck 8 are driven in the stop mode (step 46) to record the KBPS music data on the magnetic tape. To exit the mode.

As can be seen from the above description, among the KBPS data displayed on the monitor, the user selects and stores the music type, singer, popularity ranking, and other kinds of KBPS music data selected on the magnetic tape.

As described above, according to the present invention, a user can record only necessary information among KBPS music data transmitted from a broadcasting station on a separate magnetic tape, thereby reducing the capacity of a memory for storing KBPS data. have.
