Description

Video cassette recorder control method

The present invention relates to a video cassette recorder (hereinafter, abbreviated as VCS), and more particularly, to a control method of V-seal performing reservation recording using KBPS (Korea Broadcasting Program System) data. .

KBPS inserts and transmits additional data, such as reserved recording and text information, in a vertical blanking interval of a broadcast video signal, and performs program reservation, text multicasting, etc. according to the KBPS data. It is one of the broadcasting methods that enable.

That is, the broadcast program information of KBPS data includes broadcast program information by date for a predetermined period, for example, one week, and the broadcast program information by time is included in each broadcast program information by date.

Therefore, the viewer can set the reserved recording of the desired broadcast program while checking the broadcast program information displayed on the television screen, and then performs the reserved recording of the broadcast program to which VRC is set.

However, in general, the reservation recording condition of VRC must be turned off at the start of reservation, and also the cassette tape must be inserted in VLC, so that these conditions are not satisfied by the viewer's ignorance or mistake. Cases often occurred.

In this case, since V-AL resets the set reservation information, there is a problem that the reservation recording fails.

Accordingly, the present invention has been made to solve such a problem, and by resetting the set recording information of the reserved recording error program among the broadcast programs contained in the KBPS data to the recording information of the re-broadcast program, The purpose is to provide a control method.

That is, the present invention provides a control method of a video cassette recorder in which a scheduled recording is performed using KBPS data including a plurality of broadcast program information for each date within a predetermined period having a reserved recording start time data. A first step of displaying a plurality of broadcast program information corresponding to an input date among broadcast program information within a predetermined period when is set; Determining whether a predetermined broadcast program is selected from a plurality of broadcast programs, and determining whether a current time reaches the scheduled recording start time when a predetermined broadcast program is selected; A third step of determining whether the video cassette recorder is powered on / off and whether a cassette tape is inserted into the video cassette recorder when the reserved recording start time is reached; A fourth step of retrieving KBPS data when the power is on or when the cassette tape is not inserted; As a result of the search, it is determined whether rebroadcast program information having a search code that matches the search code of the set broadcast program information exists. If the rebroadcast program information exists, the reserved recording start time of the set broadcast program information is set to the scheduled recording start time of the rebroadcast program information. It provides a control method of a video cassette recorder comprising the fifth step of changing to.

The above objects and various advantages of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic block diagram of a VRC for performing a method according to the present invention, which includes a key input unit 10, a microcomputer 20, a timer 22, a memory unit 30, and an on-screen display (OSD) 40. ), Deck 50, KBPS detection unit 60 and the power supply unit 70.

As shown, the key input unit 10 includes a plurality of function keys (not shown) for controlling the operation of the V-Cal, such as a power on / off key, and corresponds to a key that is input, that is, pressed by a user. And apply the key signal to the microcomputer 20.

The memory unit 30 stores reservation information of broadcast programs set by a user, and when reservation recording start time comes, the reservation information is read by the microcomputer 20 which will be described later.

The KBPS detection unit 60 detects KBPS data among the received broadcast signals and provides them to the microcomputer 20. The KBPS data includes broadcast program information for each day of a predetermined period, for example, seven days.

The deck 50 includes a capstan motor and a head drum for driving the video tape, and a video and audio head for recording and reading video signals and audio signals, respectively, and the recording processing system under the control of the microcomputer 20. Video signal is recorded on a video tape, or a signal of the video tape is read and applied to a reproduction processing system. In addition, the deck is equipped with an on / off switch (not shown) for determining whether the cassette tape is inserted, and outputs a logic signal according to whether the cassette tape is inserted into the microcomputer 20. Whether the cassette tape is inserted or not can be easily understood by those skilled in the art, and a detailed description thereof is omitted.

The power supply unit 70 supplies or cuts power to the VC according to the power control signal of the microcomputer 20, and provides a current power on / off status signal to the microcomputer 20.

Under the control of the microcomputer 20, the OSD 40 text-processes a predetermined broadcast program into a displayable signal and provides it to a television screen (not shown).

The microcomputer 20 according to the present invention controls the overall driving of the VR and outputs a control signal for displaying a broadcast program for each date selected by the key input unit 10 among the KBPS data provided from the above-described KBPS detection unit 60. do. In addition, if the current time reaches the scheduled recording start time and the power-on state or the cassette tape is not inserted, the microcomputer 20 searches for the broadcasting code of the same rebroadcast program as the broadcast program currently set for the reserved recording, and the same rebroadcast program is executed. If present, the recording start time of the currently scheduled recording program is changed to the recording start time of the rebroadcast program.

That is, the timer 22 is provided in the microcomputer 20, and the present time is counted and the time count value is provided to the microcomputer 20.

Hereinafter, the above-described configuration will be described in detail with reference to the flowchart of FIG. 2 attached to a process of resetting the setting recording information of the reserved recording error program according to the present invention to the recording information of the re-broadcast program.

First, when the KBPS data search mode for performing scheduled recording using the KBPS data is set (S100), the microcomputer 20 receives a plurality of broadcast program information corresponding to an input date among broadcast programs within a predetermined period, for example, 7 days. After controlling the OSD 40 to display, the process proceeds to step S102.

In step S102, the microcomputer 20 determines whether a key signal for setting reserved recording information of a predetermined broadcast program is applied from the key input unit 10. Such reservation recording information setting may be performed by selecting a desired broadcast program using a shift key or a ten key on the key input unit 10 while checking a plurality of broadcast programs.

As a result of the determination in step S102, when predetermined broadcast program information is set, the microcomputer 20 proceeds to step S104 to determine whether the current recording time reaches the scheduled recording start time of the set broadcast program.

If the reserved recording start time is reached, the microcomputer 20 proceeds to step S106 to determine the power on / off state of the power supply unit 70 and the presence or absence of cassette tape insertion in the deck 50.

As a result of the determination in step S106, if the power is on or the cassette tape is not inserted, the microcomputer 20 proceeds to step S110 to search for KBPS data provided from the KBPS detection unit 60, and sets the broadcast program. It is determined whether there is a broadcast program having the same search code as that of the search code, that is, a rebroadcast program (S112).

As a result of the determination in step S112, if there is a re-broadcast program, the microcomputer 20 proceeds to step S114 and changes the reserved recording start time of the currently set broadcast program to the reserved recording start time of the detected re-broadcast program.

Therefore, even when the reserved recording fails due to the power-on state or the cassette tape insertion state described above, if the re-broadcast program exists, the reserved recording can be retried again.

As described above, the present invention has the effect of reducing the probability of the scheduled recording failure of VRC.
