3 to 12, the present invention is not limited.

The apparatus and method for reserved recording and playback of a TV according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, the user connects the back of the TV 100 and the VCR 200.

That is, as shown in FIG. 3, the user connects the antenna and the RF input of the VCR 200, the RF output is connected to the RF input of the TV 100 through a signal line, and the video and audio of the VCR 200. The output is connected to the external input 1 of the TV 100 via the video and audio AV lines, and the EZ-LINK of each of the TV 100 and the VCR 200 is connected through the one-line data communication line.

As shown in FIG. 4, the tuner 101 of the TV 100 receives RF from the VCR 200 and outputs a composite video signal. The EPG 102 then controls the electronic program guide according to a composite video signal included in the RF received at the tuner 101. In addition, the control unit 103 is connected to the EZ-LINK (1 line communication) of the VCR 200 and is connected to the EPG 102 by a serial communication line to control the operation of the entire circuit.

Thereafter, when the user turns on the power of the TV 100 and the VCR 200 and selects a desired channel through the remote control of the TV 100, as shown in FIG. 5, the tuner 101 of the TV 100 is The RF is received from the VCR 200 and output.

The EPG 102 then receives a composite video signal included in the RF received by the tuner 101 to control the electronic program guide.

That is, the broadcast guide decoding and control unit 102a of the EPG 102 decodes the signal received from the tuner 101 and stores it in the reserved recording information storage unit 102b.

Accordingly, the image controller 104 processes the signal received from the tuner 101 and outputs the resultant signal, and the CPT controller 105 outputs the signal output from the image controller 104 to the CPT unit 106. Display via.

In this state, when the user requests the reservation recording menu using the remote controller, the controller 103 outputs an OSD signal corresponding thereto.

Then, the image controller 104 performs image processing on the broadcast guide decoding of the EPG 102 and the channel guide output signal output from the controller 102a and the signal received from the tuner 101, and then performs the CPT through the CPT controller 105. After controlling the unit 106 to display the EPG screen as shown in FIG. 7 to which the "reserved recording" item is added according to the present invention, if the user sets the "reserved recording" item in the EPG menu, the EPG 102 Displays the reservation related information, that is, the start time and end time of the program to be recorded, on the TV 100 (S1, S2).

On the other hand, Figure 6 is a current EPG screen, when the user sets the "reservation" item and watching a different channel channel switching is made at the start time of the selected program to display the selected program on the screen.

In addition, the image controller 104 performs image processing on the OSD signal output from the controller 104 and the signal received from the tuner 101 and displays the image on the CPT unit 106 through the CPT controller 105. The CPT controller 105 is image-processed by the broadcast guide decoding and the channel guide output signal output from the control unit 102a, the OSD signal output from the control unit 104, and the signal received from the tuner 101. It may be displayed on the CPT unit 106 through.

Subsequently, when the user saves the recording reservation on the TV 100, the control unit 104 of the TV 100 stores the recording reservation information in the reserved recording information storage unit 102b of the EPG 102, and then Ez-Link (1). Line communication) to check whether the VCR 200 is in a recordable state (S3 to S5).

The search of the recordable state is performed by the control unit 104 of the TV 100 at a predetermined period.

If it is impossible to record the search result in S5, the control unit 104 of the TV 100 displays an error message as shown in FIG. 9 (S6).

The error message above is "No recordable tape", "No recordable channel", "No tape", "Record reservation time overlapped", "The tape length for recording is short. . " Etc.

If the search result recording in S5 is enabled, the control unit 104 of the TV 100 displays a play reservation screen as shown in FIG. 11 and asks the user whether to automatically play the recorded program at a desired time. If the user wants to play by selecting the "Scheduled Play" item (S7).

Thereafter, the control unit 104 of the TV 100 checks the recording reservation time and the recording stop time to search for the recording start time (S8, S9).

If the search result is the recording start time in S9, the control unit 104 of the TV 100 outputs a recording start command to the VCR 200 through Ez-Link (1 line communication), and then repeats the process of S8 or less. do.

Then, the control unit 201 of the VCR 200 starts recording of a program received from the antenna according to the recording start command of the TV 100, and displays the current recording status during recording reservation as shown in FIG.

In FIG. 10, (a) shows the current channel / time / voice state, (b) shows the current recording information when the VCR 200 is in the reserved recording mode, and (c) shows the state of the current recording tape. 1 indicates the start point of the tape, 2 indicates the end point of the tape, 3 indicates the point where the reserved recording starts, 4 indicates the current reserved recording point, and 5 indicates the point where the reserved recording ends.

If the result of the search in S9 is not the recording start time, the control unit 104 of the TV 100 searches for whether the recording end time is repeated, and if it is not the recording end time, repeats the process of S8 or less (S11).

If the result of the search in S11 is the recording end time, the recording end command is output to the VCR 200 through Ez-Link (1 line communication), and the control unit 201 of the VCR 200 ends the recording of the TV 100. Recording ends according to the command (S12).

Thereafter, as shown in FIG. 12, the control unit 104 of the TV 100 searches for reserved recording and stores the recording time and the reservation start time after subtracting the recording time from the recording end time. Search whether the reserved playback start time has passed the current time (ST1 to ST3).

If the current time has elapsed as a result of the search in ST3, the reserved playback is not performed. If the current time has not elapsed, it is searched whether the reservation playback start time and the current time match (ST4).

If the result of the search in ST4 does not match the current time, the process of ST3 or less is repeated, and if it matches with the current time, the user searches whether the user wants to play (ST5).

When the user wants to play the result of the search in ST5, the control unit 104 of the TV 100 outputs a rewind command to the VCR 200 through Ez-Link (1 line communication), and the control unit of the VCR 200 ( 201) rewinds the tape according to the rewind command (ST6).

Then, the control unit 104 of the TV 100 checks the rewinding of the VCR 200 and searches whether it is a recording start point (ST7).

If the search result is the recording start point in ST7, the control unit 104 of the TV 100 outputs a playback command to the VCR 200 through Ez-Link (one-line communication), and switches the TV mode to an external input (ST8). ).

Accordingly, the control unit 201 of the VCR 200 plays back the recorded program according to the playback command of the TV 100, and searches whether the recording time matches the playback time (ST9).

If the result of the search in ST9 does not match, the control unit 104 of the TV 100 repeats the ST9 until the reproduction of the recorded program is completed. 200) to output the VCR power off command and restore the TV mode to the original channel.

Then, the control unit 201 of the VCR 200 turns off the power according to the power off command of the TV 100.

As described above, the apparatus and method for reserved recording and playback of a TV according to the present invention enables various operations on a TV using various functions, so that the user conveniently sets the scheduled recording of a program and watches TV. By knowing the current recording situation in detail, there is an effect that can provide convenience in use.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
