BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reserved recording circuit of a television broadcast program, and more particularly, to a reserved recording circuit of a television receiver using teletext, which makes it possible to easily perform reservation recording using a guide screen of a broadcast sequence of teletext.

At present, a so-called TVCR, which integrates a TV and a video cassette recorder (VCR), is commercialized.

In general TVCRs as well as such TVCRs, scheduled recording is performed by inputting G codes that are set differently for each program or by inputting time of a broadcast program to be reserved.

However, in the case of the G code, since the input is a complicated sequence of numbers, the input operation is complicated and there is a problem in that incorrect input is often caused by confusion.

In addition, the time setting method has to accurately set the time of the built-in timer of the VCR, check the broadcasting time of the program, and has a hassle to input it by using the numeric keys of the remote control device.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a reservation recording session of a television receiver using teletext, which can easily perform reservation recording using a guide screen of a teletext broadcast sequence.

The reservation recording circuit of the television receiver using the teletext of the present invention for achieving the above object includes a tuner 1 for tuning broadcasts and a data slicer 2 for detecting a teletext signal from a broadcast signal output from the tuner 1. ), A display for storing a signal corresponding to the screen of the CRT among the teletext processing RAM 3 storing the teletext signal detected by the data slicer 2 and the teletext signals stored in the teletext processing RAM 3 A RAM 4, a character ROM 5 for outputting character data according to a teletext signal stored in the display RAM 4, display means 6 for driving a CRT in accordance with an output signal of the character ROM 5, The display RAM 4 and the teletext processing RAM 3 are controlled to be displayed on a CRT screen of a television on a teletext screen, and a reserved recording device on a screen of a broadcast guide. The first microcomputer 7 holding the stored contents of the display RAM 4 at the time of selection, the OSD device 8 displaying the selection means on the screen for reserved recording on the screen, and the program to reserve recording. Is selected and read by the first microcomputer 7 via the display 7 and the I / O interface at that time to detect the reservation recording time, and the second microcomputer 9 And storage means 10 for storing data relating to the reservation recording time detected by the "

According to the present invention having the above configuration, it is possible to easily perform the scheduled recording while the user confirms the program to be scheduled recorded on the teletext broadcast guide screen.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a block diagram showing the configuration of a reservation recording circuit of a television receiver using teletext according to the first embodiment of the present invention.

As shown in FIG. 1, a reservation recording circuit of a television receiver using teletext includes a tuner 1 for tuning broadcasts and a data slicer 2 for detecting a teletext signal from a broadcast signal output from the tuner 1; ), A display for storing a signal corresponding to the screen of the CRT among the teletext processing RAM 3 storing the teletext signal detected by the data slicer 2 and the teletext signals stored in the teletext processing RAM 3 A RAM 4, a character ROM 5 for outputting character data according to a teletext signal stored in the display RAM 4, display means 6 for driving a CRT in accordance with an output signal of the character ROM 5, The display RAM 4 and the teletext processing RAM 3 are controlled to be displayed on the CRT screen of the television on the teletext screen, and at the time of selecting the reserved recording function on the screen of the broadcast guide. A first microcomputer 7 holding the stored contents of the display RAM 4 at that time, an OSD device 8 displaying on-screen selection means for reserved recording on the screen, a program to be reserved recording is selected and When the contents of the display RAM 4 at that time are held by the first microcomputer 7, the second microcomputer reads them through the I / O interface with the first microcomputer 7 to detect the reservation recording time. And a storage means 10 for storing data relating to the reservation recording time detected by the computer 9 and the second micro computer 9.

Referring to the operation of the present invention configured as described above in detail.

For example, if the user selects the next program (program II) after selecting on the screen by the OSD device 8 of the broadcast program (program I) to be scheduled recording, the user selects the next program (program II). Scheduled recording is to be performed during the time between the two sessions.

Further, the second microcomputer 9, which is the main microcomputer of the TVCR device, operates the recording circuit at a designated time according to the storage contents of the storage means 10 to perform scheduled recording.

The present invention is not limited to the above embodiments, and may be modified without departing from the technical gist of the present invention.

As described above, according to the present invention, when the user wants to make a scheduled recording on the screen of the teletext broadcasting guide screen, the contents of the display RAM 4 at that time are stored by the first microcomputer 7. In addition to being held, selection means are displayed on the screen by the OSD generator 8.

When the user selects a program to reserve recording using this selection means, the second microcomputer 9 detects the time of reserved recording on the basis of the contents of the display RAM 4, and stores the time of the reservation recording. 10) and make reservation recording based on this data.

Accordingly, the user can simply store the reserved recording by selecting the necessary program in the displayed broadcast sequence using the selection means.
