Abstract

The appts. for programme reservation in a VCR has a G-code input device for published codes associated with broadcast programs. a first memory stores channel positions and tuning data, and a second memory stores broadcast station codes and names. A decoder converts the G-code data into reservation recording data contg. a guide channel number, and a controller governs the reservation recording of the VCR in response to outputs from the memories and from the decoder. A tuner receives a desired broadcast signal in response to a control signal, and a pilot signal detector sense a pilot signal from the tuned signal. A recording device records the tuned signal, and an on-screen display outputs an OSD signal under controller operation. A third memory stores the broadcast data and the corresp. guide channel numbers, and user selected channel data from the first memory. A fourth memory stores reservation recording data from the decoder and a selected channel position from the third memory.

The present invention relates to a G-code reserved recording method, and more particularly, to an apparatus and a method for automatically mapping a G-code guide channel using an ACMS (Auto Channel Mapping System) device.

In the conventional G-code reservation recording method, channel mapping is necessary to match the current channel with the method channel shown in the TV guide in order to input the reservation recording.

That is, to set the guide channel as shown in FIG. 1, it is necessary to find a channel currently received in the region.

For example, in case of domestic broadcasting, the guide channel of KBS is 4 and the guide channel of MBC is 11. However, depending on the region, the received channel may be different. Therefore, this channel must be manually aligned with the guide channel by the user. This should be done again when the region changes or when the guide channel information is deleted due to a power outage.

Therefore, in the conventional G-code reservation method, the trouble of having to manually set the channel guide channel currently received before the program reservation input occurs.

The present invention has been made to solve the above disadvantages, and an object thereof is to solve the disadvantage of manually setting the guide channel by using the ACMS device. When explaining the present invention for achieving the above object with reference to the accompanying drawings as follows.

2 is an explanatory diagram of a channel mapping method of the present invention, and FIG. 3 is a block diagram of a channel mapping apparatus of the present invention, and FIG. 4 is an operation flowchart of the channel mapping method of the present invention. ) Format is the channel position of the currently received VCR as shown in FIG. 2, and the name of the station is the name of the station to be detected by the ACMS device, and the guide channel is a channel for each station. It shows the assigned guide channel. Thus, one station of a G-code channel has one G-code channel, and the guide channel of each region is configured to set a guide channel corresponding to each channel in the microcomputer. That is, the ACMS device distinguishes among broadcaster names recorded on scan lines which do not appear on the TV.

According to this principle, the apparatus for mapping the G-code channel is output via the broadcast signal tuner 8, the video demodulator and the OSD via the antenna Ant 7, as shown in FIG. ACMS processor (5) for separating the data corresponding to the broadcast station name from the video signal output from the grandfather and separating the data corresponding to the broadcast station name, and a memory unit for recording the channel position (CP) currently being received (EEPROM). (1) and the broadcasting station name stored for each channel position (CP) stored in the ACMS processor 5 data and the memory unit 1 according to the input signals of the remote controller 3 and the key control unit 2. The microcomputer 4 controls to store data by comparing the guide channel with the memory unit 1 and compares the data with the corresponding broadcasting station name, and the OSD unit 6 displays the guide channel searched by the microcomputer 4. It is composed. The detailed operation explanation for this is as follows. The broadcast signal through the antenna 7 is received by the tuner unit 8 and the tuner 8 outputs the data tuned by the microcomputer 4 according to the user's key signal, thereby performing the right tuning to the selected broadcast channel. And an audio signal (not shown) and a dual video signal is input to the ACMS processor 5.

The ACMS processor 5 slices and decodes the data corresponding to the broadcast station name in the video signal, detects the broadcast station name, sends the decoded data to the microcomputer 4, and stores the current broadcast station channel as the channel position. Compares the pre-designated reference data of the microcomputer 4 that stores the reference data corresponding to the broadcasting station name with the decoded data of the received broadcasting signal, detects the broadcasting station name, and uses the currently received channel as a guide channel. Save it to 1).

When the process is mapped to the memory unit 1 and checks the data stored in the memory unit 1, the display may be displayed on a monitor (not shown) through the OSD (On Screen Display) unit 6. .

The mapping memory of the guide channel can be mainly used by the user during the initial channel search. Details of the search are shown in FIG.

First, when the user inputs the ACMS search key for the guide channel mapping, the microcomputer 4 receives the key data and checks the search mode to perform the search sequentially. In the case of Korean broadcasting, 2ch to 83ch are performed.

In other words, starting the search of the 2ch unit, the microcomputer checks the name of the broadcasting station, and if there is no broadcasting station name, sends the tuning data to the tuner 8 to the next ch and receives the 3ch to sequentially check the broadcasting station name.

If the user searches in Busan, the user will search the received channel with data corresponding to the channel (channel location) of the central region (Seoul region) currently stored in the microcomputer (4). If the ACMS processor 5 slices and decodes the data corresponding to the broadcast station name among the received broadcast signals, and receives the broadcast station name data from the microcomputer 4, it compares the broadcast station name data stored in the memory unit 1 with the broadcast station name. MBC is detected.

Therefore, channel 7 becomes a guide channel in the Busan area, and stores the guide channel in the memory unit 1, and this embodiment is mapped as shown in the table of FIG. 2.

The memory unit 1 uses EPROM in the embodiment of the present invention, but may be used as a RAM.

In addition, in the ACMS search mode, the OSD unit 6 may display a state of being memorized. When the user wants to check the mapping data stored in the memory, the mapping state may be checked by pressing the ACMS menu key.

As described above, the G-code channel mapping method of the present invention eliminates the channel mapping step, which is a disadvantage of the G-code reserved recording, so that the G-code reserved recording can be easily performed regardless of the region even if the user does not know the channel mapping. It works.
