Description

How to Correct Scheduled Recording Time in TV Video

The present invention relates to a scheduled recording method in television video (hereinafter referred to as TVCR), and more particularly, when a scheduled recording of a television program is performed, the recording time can be fully recorded even if the end time of the program fluctuates due to fluctuating time. The end time of reservation recording is also related to the correction method of reservation recording time so that it may be extended in connection with this.

In general, the components of the TVCR will be described with reference to FIG. 1.

The microprocessor 200 which controls the overall operation of the TVCR, the memory unit 240 storing various data to be processed by the microprocessor, and the broadcast signal of the channel selected by the channel voltage output from the microprocessor There is a tuner 100 that receives and tunes from an antenna, an image processor 400 for processing video signals of broadcast signals tuned by the tuner, and an audio processor 300 for processing audio signals.

In addition, there is a vertical / horizontal synchronization processor 600 for deflecting the vertical synchronizing signal and the horizontal synchronizing signal of the image signal, and an image receiving tube 700 which receives the image signal output from the image processor and displays it on the screen. Then, there is a video deck 500 that records or reproduces video signals and audio signals such as video tapes.

A reservation recording process of a general TVCR configured as described above is as follows.

The viewer inputs a channel through which the program to be scheduled recording is broadcast, its start time and end time through the key input unit 220, and presses the reservation recording setting key. The microprocessor 200 stores the settings set by the user in the memory unit 240 and waits until the reserved recording time is reached by using the built-in timer.

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

The processed signal may be output to the speaker 800 or the water pipe 700, but when the power of the water pipe is off, only the video deck 500 is output. 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 from the tuner 100 to the video deck 500 via the microprocessor 200 and recorded together.

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 are, and may be extended later, or may be extended for more than five minutes depending on sudden feature broadcasts. In the case of recording a movie broadcast, the length of the airing time varies for each movie, which may be several ten 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.

The present invention for solving the above-described problems is linked to the end time of the scheduled recording in such a manner that when the scheduled recording of a TV program is possible to record the entire program even if the time to end the program fluctuates due to a broadcast situation. It is an object of the present invention to provide a method of correcting a reserved recording time which is to be extended.

A feature of the present invention for achieving the above object is a television broadcast program that is transmitted by a broadcasting station that transmits KBPS information, which is various peripheral information (ID, etc.) other than the television broadcast program, at predetermined time intervals and is transmitted wirelessly together with the television broadcast program. A program system module 900 for receiving, a timer 210, a memory unit 240 for storing data for reservation recording, a video deck 500, and a microprocessor for overall control of various operations ( In a reservation recording method for a television video having 200):

The microprocessor 200 is configured to detect an ID of a program to be reserved by using the timer 210 using a predetermined program system module 900 from a predetermined time before the end time of the scheduled recording. In a first step (S20) and the second process of extending the end time of the scheduled recording until the ID of the program to be detected in the first process is not detected a predetermined number of times in succession to perform recording on the video deck (500) It is in including.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

2 is a block diagram of a TVCR according to an embodiment of the present invention, which is different from the conventional configuration, in that a KBPS (Korean Broadcast Program System) which decodes a data signal for a broadcast program from a signal output to the tuner 100 is shown. ) Module 900 is further included.

The KBPS module 900 includes a decoder 910, a controller for processing data output by the decoder, and a ROM that stores an execution program of the controller. The Korean broadcast program system is a system that gives IDs to broadcast programs, and transmits the IDs and information data such as broadcast order and broadcast time in a broadcast signal. The data for the program is transmitted using a gap such as vertical blanking time as in the character multicasting.

The content of the data for the program is usually the one-week program ID listed in the broadcast order. Also, the ID of the program currently being aired is located at the beginning, and the next program to be broadcasted is next. The order of enumeration of IDs is regulated. As a result, when the same ID is continuously detected at the same sequential position, the program having the ID becomes the program currently being broadcasted (at the time of decoding).

Hereinafter, a preferred embodiment of the operation process according to the present invention with reference to the accompanying drawings, 3 as follows.

3 is a flowchart for a method of automatically implementing screen selection according to an embodiment of the present invention.

During the reserved recording according to the reserved recording mode of the microprocessor 200, the timer 210 is used to check whether the current time is 5 minutes before (for example) from the reserved recording end time set by the user (S10). . Five minutes is the amount of time that the program changes over time. From this point on, the scheduled recording time will be corrected.

If the result of the check is 5 minutes ago (Yes), the unique number of the program currently scheduled recording is detected from the unique number (ID) output from the data decoder 910 of the KBPS module 900. As described above, the unique number in a particular order means a program that is currently being broadcast.

It is checked whether a predetermined number (for example, five times) of a unique number (ID) of a program currently being recorded is detected (S30). As the number of detections is detected several times in succession, the time correction aimed at by the present invention becomes more accurate.

If the program is continuously being broadcasted, the unique number is detected continuously for a predetermined number of times (Yes), and therefore, reservation recording must be continued. That is, the end time of the reservation recording is deleted (S40), and the process returns to the unique number detection step (S20).

When the broadcast program recording over time ends, it is not detected in step S30 of confirming whether the unique number of the program is continuously detected a predetermined number of times (No). Therefore, the recording is stopped and the scheduled recording of the program is stopped. End (S50).

The present invention operated as described above automatically corrects and maintains the reserved recording time range of the TVCR while the program is being broadcast, so that the user can record the program to be recorded intact. Therefore, the user is more convenient to use the reserved recording function, and as the recording is intact, there is an effect of increasing the reliability of the user's product.
