Description

Ultra-fast recording method using KBPS code

The present invention relates to a recording method in a device capable of recording a television broadcast signal, such as a VCT or TVCR, in particular, to read recording KBPS code (Korea Broadcast Program System Code) to make a recording reservation only two times the user's key operation It is about an ultra-easy recording method to enable.

In general, a VCR is a device for recording a video signal and an audio signal on a magnetizable video tape, and reproducing the video signal and a voice signal if necessary to view the video signal through a display means such as a CRT or a TV. As shown in FIG.

Referring to the configuration shown in FIG. 1, the process of recording / reproducing the received color video signal will be briefly described as follows.

First, in the case of recording, the color image signal input through the low pass filter LPF and the high pass filter HPF is separated into a luminance signal and a carrier color signal, and the separated luminance signal is FM-modulated and amplified. In addition, the separated carrier color signal has a frequency characteristic of 3.58 MHz, which is converted to a low frequency band of 767 kHz (exactly 767.0473 kHz) and amplified to a predetermined size. Thereafter, the luminance signal modulated by the FM in the mixing circuit is superimposed on a low level signal state and recorded on the tape through the video head.

On the other hand, during playback, the information recorded on the tape is accessed through the video head, and the weak signal is amplified to a predetermined size through the amplifier. The amplified signal is separated into an FM modulated luminance signal and a carrier color signal converted into a low frequency band through a low pass filter (LPF) and a high pass filter (HPF). Thereafter, the FM modulated luminance signal is restored to the original luminance signal through the FM demodulation circuit, and the carrier color signal converted to the low frequency band is inversely converted from the low frequency band of 767 kHz to the original frequency band of 3.58 MHz. At the same time, time-base fluctuations (i.e., jitter components) of the signal generated during reproduction are eliminated. Thereafter, the luminance signal and the carrier color signal are mixed through the mixing circuit to be restored to the original video signal.

Since the reproducing process of the above-described process is the reverse process of the recording process, referring to FIG. 2 attached to the conversion process of the signal according to the recording process, as follows.

FIG. 2 illustrates a video signal change process of recording a video signal in the accompanying FIG. 1 in the case of an NTSC video signal.

The overall configuration of the conventional image recording / reproducing apparatus to which the recording / reproducing technique of the video signal is applied is as shown in FIG.

Referring to the process of recording a television broadcast in the conventional VCR configured as described above are as follows.

When the user wants to record a specific television broadcast program, the user should be aware of the channel that can receive the broadcast program that he / she wishes to record, and the start time and end time of the program.

Thereafter, the user stores the stored information in the memory 500 through the manipulation of the keypad 900C or the remote controller 900A, and the microcomputer 600 starts the corresponding program based on the information stored in the memory 500. It is determined whether the time has passed through timer counting, and when the start time of the corresponding program is reached, the tuner 100 and the recording unit 300 are operated so that the broadcast received through the antenna is placed on the video tape (cassette). Will be recorded.

In addition, when it is determined that the end time of the program is reached by counting the end time, the microcomputer 600 stops the operation of the tuner 100 and the recording unit 300.

In general, however, broadcast programs published on newspapers vary slightly depending on the broadcaster's circumstances, and the programs may not be broadcast at all on the scheduled date, so the start and end times of the programs are often different. As described above, due to mismatching of the start time and end time of the program set by the user and the actual broadcast time, a complete recording of the desired program is not frequently performed.

In addition, the user has a lot of things to be aware of the program recording, the operation of the system for the program recording and the operation of the keypad (900C) or the remote control (900A) has a lot of problems that increase the inconvenience.

An object of the present invention for solving the above problems is to select the user specific key to obtain the KBPS code mixed in the broadcast signal for each channel, and then read it and display it through the OSD, if the user selects a random program To provide an ultra-easy recording method and a device using the KBPS code to enable recording reservation.

At this time, the detailed configuration of the recording unit 300 and the reproduction unit 400 is as shown in the accompanying Figure 1, the overall operation is a general description thereof will be omitted.

Looking at the preferred operation example according to the reservation recording process of the VCR according to the present invention configured as described above are as follows.

When the user selects a specific key for reserved recording, the microcomputer 600 tunes the tuner 100 to select an arbitrary channel with respect to all broadcast channels that can be received. The signal received through the channel tuned by the tuner 100 is detected and output through an IF detector 200, and the microcomputer 600 of the recording unit 300 and the reproduction unit 400 is output. Only the KBPS module 1000 is operated in the stopped state.

Accordingly, the KBPS module 1000 detects the KBPS code mixed with the intermediate frequency, decodes the KBPS code, and provides the same to the microcomputer 600.

In this case, the microcomputer 600 preferentially detects information on a specific date (for example, today) among decoding information input from the KBPS module 1000. Thereafter, guide information (eg, a broadcast program name and a corresponding program ID) of the broadcast program corresponding to the detected date is detected and stored in the memory 500.

When the program that is broadcast today is stored in the memory 500 through the above operation, the microcomputer 600 reverts to a specific date different from the previous date among the decoding information input from the KBPS module 1000 (for example, tomorrow). Information is stored, and the program guide information for the same date is also stored.

After the operation of storing all the broadcast programs of all dates provided in a specific channel, the above-described channel is tuned to another channel and the above-described process is sequentially and repeatedly performed on all of the broadcast channels.

After storing the names and IDs of the programs provided in all channels through the operation as described above, the information is provided to the OSD generator 700 sequentially from the information about the broadcast program stored first among the stored information. , Which is displayed as text, the currently displayed text will blink for a certain time.

In this way, while the specific program is displayed through the CRT or the CRT of the TV, when the user selects a specific key for selecting a recorded program by using the remote controller 900A or the keypad 900C, the microcomputer 600 selects the specific key by the user. The moment you make a selection, you will temporarily save the flashing program.

Thereafter, the information about the temporarily stored program is accessed from the memory 500 and set as setting data for performing reserved recording.

Subsequently, the microcomputer 600 determines whether a program to which the same data is added is input through the KBPS module 1000 while the corresponding channel is tuned based on the set reservation recording data. The recording unit 300 is operated to perform a normal recording function.

If the ultra-easy recording method using the KBPS code according to the present invention operates as described above, if a user selects a specific key, the KBPS code mixed with the broadcast signal is acquired for each channel, and then read and displayed through the OSD. If you select a program, you can make a recording schedule for the program.
