The present invention relates to a reservation recording and viewing method using the KBPS function, and in particular, a desired program is selected from among multiple inputs received by the TVCR through a system of KBPS (Korea Broadcasting Program Service), and recorded or monitored on an internal cassette tape. And it relates to a reservation recording and viewing method using the KBPS function to prevent duplicate recording while allowing viewing through the speaker.

In general, a TVCR (Tele Video Cassette Recorder) is used to receive a TV broadcast signal from the outside and to record it on an internal cassette tape or to reproduce a composite video signal recorded on the cassette tape so that it can be viewed through a monitor and a speaker. It is a well known fact.

In the TVCR, a user can directly record a TV broadcast signal received through an antenna and tuned in a tuner with a cassette tape inserted into a deck, or perform a scheduled recording.

Therefore, a user using a TVCR can store a TV broadcast signal received through an antenna from the outside using a cassette tape inserted in a deck while arbitrarily tuning at a desired time, or play back a composite video signal recorded on a cassette tape when needed. To make it possible.

However, according to the conventional TVCR as described above, the user can perform the reserved recording while tuning the TV broadcast signal received through the antenna while the cassette tape is inserted into the deck, so that the user can watch the program selected by the reserved recording. Even though it was just recording, there was a problem that wasted tape.

On the other hand, the scheduled recording can be arbitrarily selected, but there is a drawback that a user cannot watch a plurality of programs while automatically supplying power to the TVCR at any time that the user wants to watch except the on-time method.

Accordingly, the present invention selects a desired TV broadcast signal from the multi-input received by the function of KBPS using TVCR, applies for pre-recorded recording to be recorded on the cassette tape, and stops recording if the broadcast is received through the TVCR. The object of the present invention is to provide a reservation recording and viewing method using the KBPS function to prevent waste.

A color demodulator 19 for outputting a signal and a CRT driver for receiving a luminance signal Y, a color difference signal RY, and BY from the color demodulator 19 and expressing the image to the monitor 21 as an image. 20), a power supply unit 22 which receives AC power from the outside, voltage drops and rectifies and supplies the microprocessor 3 as operating power, and the operating power supplied by the power supply unit 22 is charged. It is composed of the backup power generators 23 to discharge the power outage.

The reservation recording and viewing method using the KBPS function of the present invention configured as described above allows recording and viewing in a non-overlapping state when a desired pro is reserved for a multi-input signal while using a TVCR. The operation process is as follows.

When the user turns on the power key (PWR) (step 30) or inserts and inserts a cassette tape (step 31), the microprocessor 3 that recognizes the power supply 22 operates the power supply 22 to supply the SMPS method. Allow power to be supplied normally (step 32).

The user confirms whether the channel up / down key CH of the key input unit 1 or the remote controller 2 is turned on (step 33), and if it is turned on, a phase control signal for selecting a television broadcast signal of a channel selected by the user Is output to the phase lock loop 8 so that the tuner 9 tunes the desired television broadcast signal among the various television broadcast signals received through the antenna 10 (step 34).

The television signal selected by the tuner 9 is mixed with the output of the local oscillator 12 by the intermediate frequency amplifier 11 to be amplified and detected so as to be output as an intermediate frequency signal of a constant frequency. Detected by the signal processor 13 and amplified by the next amplification unit 14 so that it can be heard through the speaker 15 (step 35),

The composite image signal output from the intermediate frequency amplifying unit 11 is signal-processed by the signal processing unit 17 to output an image signal to be represented as an image on the monitor 21 through the CRT driver 20 (step) 36).

It is checked whether the current time is the time of reserved recording (step 37). If it is the time of reserved recording, it is checked whether the channel currently being watched is a reserved channel (step 38).

If the channel is reserved, recording is performed by the recording head while moving the cassette tape at a constant speed (step 39), while the reserved recording program is displayed on the monitor 21 through the on-screen display IC 18 for recording. In step 40, the user selects an authorization value.

If there is no key input by the user that recording is desired, recording is stopped just by viewing (step 41), the cassette tape is returned to its initial state (step 42), and stopped (step 43).

If there is a key input by the user that recording is desired, recording is continued (step 44), and when the end time comes (step 45), the recording is stopped and stopped, and the next operation is prepared (step 46).

If the channel is not reserved in step 38, the channel is tuned (step 47), and the cassette tape is moved at a constant speed so that recording is performed by the recording head (step 48), and when the end of the recording pro is reached ( Step 49), recording stops and stops, and then prepares for the next operation (step 50).

In step 37, if it is not the time of the scheduled recording, it is checked whether the current time is the time of reserved viewing (step 51). If it is the time of reserved viewing, it is checked whether the channel currently being watched is the reserved channel (step 52).

If the channel currently being watched is a reserved channel, the channel should be switched by displaying on the monitor 21 via the on-screen display IC 18, while continuing to watch the current channel (step 53). A message according to the permission is displayed on the monitor 21 (step 54).

If there is no request for switching of the channel by the user (step 55), it is regarded as giving up reservation reservation and returns to step 53 to keep the current state, and if there is a request for switching of the channel, the channel is tuned (step 56). ).

Therefore, according to the reservation recording and viewing method using the KBPS function of the present invention, the step of supplying power when the current time is a reservation time in the state that power is not supplied,

Determining whether the channel of the television broadcast currently being watched is a reserved channel;

In the case of the scheduled recording, a recording message is displayed on the current screen while recording to confirm whether a key is input within a predetermined time period,

If there is no key input for a certain period of time, recording continues, while if there is a key input, it is performed by the steps of rewinding to the position of the first recording and watching it continuously. This prevents duplicate recording when watching.
