Abstract

PURPOSE: A method for controlling record when completing program is provided to prevent that a rear portion of a broadcasting is not recorded or a unnecessary different broadcasting is recorded by simply recording a broadcasting according to a progress of a time. CONSTITUTION: A microprocessor judges as to whether a reservation recording mode is selected by a user(S101). A broadcasting channel and a time are set when the reservation recording mode is selected(S103). The microprocessor searches a time of a timer while a reservation recording time is reached(S104,S105). The microprocessor adjusts a tuning voltage and tunes a broadcasting receiving channel as a predetermined broadcasting channel(S106). The microprocessor accesses a character for judging a recording completion and a recording operation is performed(S107,S108). A character is recognized among a video signal while the recording operation is performed(S109).

Description

Recording control method when broadcasting program end

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of performing reservation recording in television video (hereinafter referred to as TVCR). In particular, the present invention relates to a low cost video recording apparatus that performs reservation recording in dependence of a timer. In comparison, the end time of the corresponding broadcast program is frequently changed, but since the broadcast recording is performed simply by the passage of time, the rear part of the broadcast is not recorded or another broadcast is unnecessarily recorded. The present invention relates to a recording control method at the end of a program for stopping recording when a specific character indicating end of broadcasting is detected in a video signal.

In general, a TVCR is a combination of a television and a video tape recorder. It has two functions that allow a user to simultaneously watch and record different broadcasts and to play back and watch recorded video tapes or other video tapes. It is a compact product combined with.

Referring to Figure 1 attached to the conventional configuration of the above-described TVCR, a microprocessor 200 for controlling the overall operation of the TVCR, and a key input unit 220 that is a passage for the user to enter various operating modes to the microprocessor And a timer 210 for checking a reservation recording time, a tuner 100 that receives and tunes a broadcast signal of a channel selected by a tuning voltage output from the microprocessor 200 from the antenna, and the tuner. A video processor 400 is provided to process the video signal of the tuned broadcast signal, and the audio processor 300 to process the audio signal, the speaker 800, the video signal output from the video processor 400 and the horizontal Display a character or a figure on the monitor screen under the control of the microprocessor 200 For a display generation unit 600. The Then, there is a video deck 500 that records or reproduces video signals and audio signals such as video tapes.

Briefly looking at the reservation recording process of the TVCR configured as described above, the viewer inputs the channel through which the program to be scheduled recording through the key input unit 220, its start time and end time, and enters the reservation recording setting key Press The user's settings are stored in the memory unit 240 by the microprocessor 200, which is a control unit, and wait until the reserved recording time is reached by using the internal timer 210.

When the scheduled recording reaches the set time, a control signal (tuning voltage) is output to the tuner 100 to tune the program selected by the user (channel that broadcasts). The broadcast signal output from the tuner 100 is input to the audio processor 300 and the image processor 400 and then subjected to amplification.

The processed signal may be output to the speaker 800 or the monitor 700. However, when the power of the monitor is turned off, the processed signal is output only to the video deck 500 which is a recording means. The microprocessor 200 transmits a control signal to the video deck 500 to control recording (storage) of an input broadcast signal. Of course, the horizontal / vertical synchronization signal is also input to the video deck 500 via the microprocessor 200 from the tuner 100 and recorded together.

In addition, when the end time passes unconditionally, the recording process is automatically terminated based on the end time set by the user.

Therefore, in the conventional TVCR in which the reservation recording process is performed as described above, recording starts unconditionally at an arbitrary reservation time set by the user.

However, the conventional TVCR which performs the reservation recording as described above automatically records only at the reservation time set by the user through the key input means 220. In this case, there is a problem in that a part of the program is not recorded when the time zone during which the program is broadcast is changed according to the circumstances of the broadcasting station.

For example, live broadcast programs (performances, events, sports) often start later than they're scheduled, and may be extended later, or they can be extended for more than five minutes depending on a sudden feature broadcast. In the case of recording a movie broadcast, each movie has a different length of airing time, so it may be several minutes longer than the recording time of approximately 1 hour 40 minutes.

In the above cases, there is a problem that the recording of the end of the program is generally not possible as the reserved recording mode of the conventional TVCR.

An object of the present invention for solving the above-mentioned problems is that in the low-cost video recording device that performs scheduled recording depending on the timer, the end time of the broadcast program is changed in comparison with the broadcast time of the program announced due to the broadcasting station. In order to prevent the case where the trailing part of the broadcast is not recorded or other broadcasts are unnecessarily recorded because the broadcast recording is performed simply by the passage of time, a specific character indicating the end of the broadcast is detected in the video signal. The present invention provides a method of controlling recording at the end of a program to stop recording.

Referring to Figure 3 attached to the recording control process at the end of the program in the television video according to the present invention configured as described above will be described.

3 is a flowchart illustrating a recording control process at the end of a program in a television video according to an embodiment of the present invention.

First, the user sets the characters (for example, "end", "end", "final", "about next week", etc.) that can determine the end of recording by operating the key input unit 220. The character storage unit 1200 is stored.

Accordingly, the microprocessor 200 determines whether the reserved recording mode is selected by the user in step S101. If it is determined that the reserved recording mode is not selected, the microprocessor 200 proceeds to step S102 to perform a normal TVCR function. That is, it performs the function of the TV mode or the function of the VCR.

If it is determined in step S101 that the reserved recording mode is selected, the process proceeds to step S103 to set a broadcast channel and time for which scheduled recording is desired, and in step S104, the microprocessor 200 performs an internal timer 210 operation. This operation of step S104 for searching for a timer is performed until it is determined in step S105 that the reserved recording time has been reached.

Thereafter, in step S106, the tuner voltage applied to the tuner 100 is adjusted by the microprocessor 200, and the user tunes the broadcast reception channel to the broadcast channel set in the process of step S103 through the process of step S105. When entering the scheduled recording start time through the process of step S106, in step S107, characters that can determine the end of recording stored in the character storage unit 1200 are accessed. In addition, the recording operation is performed through the process of step S108.

While the recording operation is performed through the above-described step S108, the character is recognized in the video signal in step S109. In this case, referring to the character recognition process in step S109, the image memory 1000 receives and stores image signals input by the tuner 100 and input to the image processor 400 in one frame unit. The data stored in subsequent other image frames is replaced.

Accordingly, the character recognition unit 1300 that detects and recognizes a character in the image signal stored in the image memory 1000 recognizes a character mixed in the image signal of the current frame every frame. It is input to the comparator 1100. The comparison unit 1100 compares the data output from the character recognition unit 1300 with the characters stored in the character storage unit 1200 to determine whether the same character exists and determine that the same character exists. In the case of "high" status signal output.

Therefore, in step S110, the microprocessor 200 determines whether the comparison data of the "high" state is output from the comparison unit 1100 through the process of step S109. In step S108, the recording operation is performed. When the comparison unit 1100 determines that the comparison data of the "high" state is output by the determination of step S110, the recording operation is terminated.

In the low-cost video recording device which provides a recording control method at the end of a program according to the present invention which operates as described above and performs scheduled recording in dependence on a timer, the termination of the corresponding broadcast program compared to the broadcast time of the program announced by the broadcasting station. Since the time is often variable, broadcast recording is performed simply by the passage of time, thereby preventing the trailing part of the broadcast from being recorded or unnecessarily recording another broadcast.

While the invention has been shown and described with respect to particular embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention as set forth in the claims. Anyone can see it easily.
