The present invention relates to an apparatus for setting a reservation mode of a video cassette recorder using a G code. More particularly, the present invention relates to a device that automatically changes a central channel of a G code into a real channel by a broadcast station name. An automatic reservation setting apparatus for a video cassette recorder using a code.

G code is a reservation recording method developed by Gemstar, USA, to make it easier for the user to set the reservation recording function of a video cassette record (hereinafter referred to as a VCR). This method was developed by Gemstar in November 1990 and owns patents. It divides 24 hours a day into 5 minutes, assigns codes by time zone, and sets the password number combining all cases according to date and channel. This makes it easy to schedule recording of TV programs broadcasted at any time.

However, a code for designating a channel in a G code published in a newspaper or the like is generally referred to as a central channel (in this specification, a transmission channel of a headquarters broadcasting station for transmitting television broadcasts is called a central channel, and a local broadcasting station under the headquarters broadcasting station is used for local characteristics). If the channel is changed accordingly, the changed channel is called a local channel). If the local channel is to be received, the central channel selected by the channel code in the G code should be changed to the local channel.

Conventionally, for this channel conversion, the user inputs information on the central channel corresponding to the local channel to the G code remote controller using key metrics or the like. In this case, the general user may not know what the central channel corresponding to the local channel is. Therefore, this information and a channel conversion method are described in the user descriptor of the G code remote controller.

However, the general user may not know what the central channel corresponds to the local channel, and may only know the broadcasting station transmitting the central channel. Therefore, the convenience is increased when the user selects the central channel corresponding to the local channel only by the broadcast station name. Will be.

The present invention has been made in view of the above, and an object of the present invention is to provide an automatic reservation setting apparatus for a VCR using a G code that enables the central channel to be changed to a local channel only by a broadcasting station name.

A feature of the present invention for achieving the above object, in the automatic reservation setting device of the VCR using the G code, the local channel for driving according to the application of the channel setting signal to output the local channel data according to the drive of the local channel setting key Change section; A broadcasting station changing unit which drives in response to the application of the channel setting signal and outputs broadcasting station data according to the broadcasting station selecting key; A center channel changer for outputting a center channel signal according to driving of the broadcasting station data and the center channel setting key; A storage unit which drives in a storage mode when the channel setting signal is applied to store the local channel data and the central channel signal so as to correspond to each other, and stores local channel data corresponding to the central channel signal applied in the output mode; An automatic reservation setting apparatus for a VCR using a G code having an OSD unit for outputting another OSD signal to the local channel data, broadcasting station data, and center channel signal.

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

1 is a block diagram of an automatic reservation setting apparatus for a VCR using a G code according to the present invention, where code 1 is a key input classification unit. At this time, the key input classification unit 1 is configured to classify and output a key signal of a key drive related to channel setting among the key signals of the key matrix 10 when the channel setting signal is applied from the channel setting unit 2. When the channel setting key is not applied, the key related to the channel among the G codes is classified and output. Keys related to channel setting in the present invention include a local channel setting key, a center channel setting key, and a broadcasting station selection key. At this time, the local channel key can be used as a channel increase / decrease key formed in a general remote controller, and the broadcast station selection key can be set as (+) and (-) keys. The center channel setting key may be a numeric key (0 to 9) for the user to manually select a center channel.

The local channel changing unit 3 connected to the key input classification unit 1 and the channel setting unit 2 is driven when the channel setting signal is applied and is outputted according to the driving of the local channel setting key. It is configured to change the data and output it. For example, if the local channel setting key is a channel increase / decrease key as described above, when the channel increase key is driven, the channel data are sequentially output in the order of increasing the channel number. It is configured to output channel data sequentially in decreasing order.

The broadcasting station changing unit 4 connected to the key input classifying unit 1 and the channel setting unit 2 stores data for a plurality of broadcasting stations and operates upon application of the channel setting signal to drive the broadcasting station setting key. And change the output broadcasting station data. For example, when the broadcasting station selection key is configured with the (+) and (-) keys as described above, the broadcasting station data is sequentially output as the (+) or (-) key is pressed.

In addition, the broadcasting station changing unit 4 is configured to change and output broadcasting station data according to the channel data of the local channel changing unit 3.

The central channel changing unit 5 connected to the key input classifying unit 1 and the channel setting unit 2 stores central channel signals corresponding to the broadcasting station data, and transmits predetermined broadcasting station data from the broadcasting station changing unit 4. Is applied to output a corresponding center channel signal. The center channel changing unit 5 is configured to change and output the center channel signal corresponding to the broadcasting station data in response to the operation of the numeric keys 0 to 9.

The storage unit 6 connected to the local channel changing unit 3 and the central channel changing unit 5 operates in a storage mode when the channel setting signal is applied to the local channel data of the local channel changing unit 3. The central channel signals of the central channel changing unit 5 are configured to be stored in correspondence with each other. When driving in an output mode, local channel data corresponding to the input central channel signal is output.

The OSD unit 7 is configured to input the local channel data, the broadcasting station data, and the central channel signal, and output an OSD signal which can be displayed on the water pipe as characters.

The above-described configuration is a functional block diagram for briefly expressing the basic idea of the present invention, and may be configured using a microcomputer and a storage means. The operation of the present invention configured as described above will be described in detail according to the flowchart of FIG.

First, when the user presses the channel setting key of the remote controller (S1), the channel setting unit 2 determines whether the internal flag is set, resets it at set time, and sets it at rest (S2 to S4). At this time, when the flag is set, the channel setting unit 2 drives in the channel setting mode for outputting the channel setting signal, and thus the driving and stopping of the channel setting mode is controlled as the channel setting key is pressed.

When the flag is set by performing step S3, the channel setting section 2 outputs a channel setting signal to the local channel changing section 3, the broadcasting station changing section 4, and the central channel changing section 5; Starts driving to output the previously determined local channel data, broadcasting station data and center channel signal (S5). At this time, the OSD generation unit 7 also starts driving by the channel setting signal, so these signals are displayed on the receiving tube as characters, as shown in FIG. 3A (S6). Thereafter, when the local channel change key is driven (S8), the local channel change unit 3 changes the local channel data that has been output, so that the regional channel is changed as shown in FIG. 3b and the broadcasting station change unit 4 is performed. The broadcasting station data is changed and output according to the change of the local channel data. At this time, the central channel changing unit 4 will change and output the central channel signal corresponding to the broadcasting station data of the broadcasting station changing unit 4. Therefore, the screen will be changed as shown in FIG. 3B, and the storage unit 6 stores the state as shown in FIG. 3B (S9). In the state of FIG. 3B, if the broadcasting station name and the central channel corresponding to the local channel are wrong, the broadcasting station name and the central channel should be changed.

First, the case of using the broadcast station changing key will be described. In the case of using the broadcast station changing key, all of the broadcasting station central channels corresponding to the local channel are wrong.

When the screen is displayed as shown in FIG. 3B, when the broadcasting station changing key (+ or − key) is pressed (S10), the broadcasting station changing unit 4 changes and outputs the broadcasting station data. In this case, since the central channel changing unit 6 is configured to output the central channel data corresponding to the central channel data corresponding to the broadcasting station data, the central channel corresponding to the broadcasting station data applied by the current broadcasting station changing unit 4 eventually. The data is converted into data and output (S11). Accordingly, a state in which the central channel data and the broadcasting station data are converted on the screen of FIG. 3B is displayed on the screen displayed by the OSD unit 7 as in FIG. 3C, and the storage unit 6 is also in the same state as on the 3C chart. In other words, central channel data and broadcasting station data corresponding to local channel data are stored.

In the state of FIG. 3B, if the broadcasting station corresponding to the local channel is correct but the center channel is wrong, the user can change the center channel data by pressing a key corresponding to the center channel among the numeric keys 0 to 9.

When the user presses the numeric key 7 when the screen shown in FIG. 3B is displayed (S12), the center channel changing unit 5 changes the channel data as the number 7 is pressed and outputs the changed channel data. . Since the channel data of the channel changing unit 5 is applied to the OSD unit 7 and the storage unit 6, a character such as a 3d diagram is displayed on the screen, and the storage unit 6 is also located in the same state as the 3d diagram. Corresponding to the channel data, central channel data and broadcasting station data are stored (S13).

As described above, the user who knows the center channel corresponding to the local channel can set the center channel irrespective of the broadcast station name. Therefore, the center channel can be changed, that is, the center channel can be set only by the numeric keys. That is, the user can set the center channel corresponding to the local channel as the broadcast station name, and the center channel corresponding to the local channel can be set even if the central channel is changed.

When the above-described channel setting mode ends, that is, when the user presses the channel setting key again, the user sets the key metrics of the remote controller corresponding to the G code when the flag of the channel setting unit 2 is reset. Then, the key input classifier 1 classifies only the signal corresponding to the channel code among the key matrix key signals and applies it to the storage unit 6. In this case, since the channel setting signal is not being applied, the storage unit 6 is driven in the read mode to search for and output local channel data corresponding to the input channel signal (S7). At this time, since the channel signal applied from the key input classification unit 1 is a signal corresponding to the center channel, the channel data output from the storage unit 6 becomes local channel data of the region corresponding to the channel code of the G code. . Since the channel data outputted to the storage unit 6 is applied to a tuner (not shown) at a later stage, the broadcast signal received by the VCR becomes a local channel broadcast signal of the region corresponding to the channel code of the G code.

As described above, the present invention allows the broadcasting station name designated by the user and the central channel signal corresponding to the broadcasting station name to be synchronously changed, so that the user can select the central channel corresponding to the local channel only by the broadcasting station name when the central channel corresponding to the local channel is not known. This has the effect of being set.
