Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to each region regarding how many channels a television broadcasting station is transmitting when presetting a channel of a television receiver equipped with an electronic tuner for broadcasting in that region. By storing the data in the receiver side and inputting the code (called the area code) that specifies the area at the time of channel presetting into this receiver, the data of the television broadcasting for each area stored in the receiver The present invention relates to an area broadcasting channel setting method and apparatus for presetting a broadcasting channel suitable for the area to a channel position of a receiver.

[0002]

2. Description of the Related Art A channel presetting operation for setting (storing) a channel of a television broadcast to be received by a receiving device using a frequency synthesizer (FS) system as a system for receiving a television broadcast is performed. Call. Generally, the broadcasting channel set in each channel position in this way is selected by selecting the channel position.

There are various kinds of channel presetting methods, and typical methods and their drawbacks will be described.

(1) Auto search system Receiving broadcasts are searched for from low frequency broadcasts, and the broadcasts that can be received are automatically preset to the channel positions one by one, and the desired broadcasts cannot be set to the desired channel positions. There are drawbacks.

(2) Search method This is a method in which a desired broadcast is searched for and, when it is received, a presetting operation for the desired channel position is performed for each channel position, and there is a drawback that the setting operation is troublesome.

(3) Method of directly presetting the channel of the desired broadcast to be set for the channel position without receiving the broadcast There is a disadvantage that the setting cannot be made unless the desired broadcast is known.

(4) Automatic setting method of regional broadcasting channel Data regarding each region regarding which channel the television broadcasting station is transmitting is stored in the receiver side, and an regional code for designating the region at the time of channel presetting is set. This is a method of inputting to the receiver and presetting the channel of the broadcast suitable for the region to the channel position by the data of the television broadcast for each region stored in the receiving device.

[0008] This method is an excellent setting method which has the advantage that the desired broadcast channel can be set accurately at the desired channel position, but the drawback is that it is necessary to input a code designating the region.

Now, the method (4) will be described.

The ground wave of television broadcasting has a limited area where radio waves emitted from its transmitting station (hereinafter referred to as a station) can be received, and it is impossible to cover the whole country with one station. Exists.

A plurality of television broadcasts are transmitted from the station, and the frequency (broadcast channel) of the radio waves transmitted by the television broadcasts differs from station to station in order to prevent interference. (However, not all stations are different, but the same may be said for non-adjacent stations.) The fact that the transmission channels from each station are different means that the same broadcasting channel varies depending on the region. In the automatic setting of regional broadcast channels, the number of channels of a plurality of television broadcasts transmitted from each station is stored in advance in association with the channel position, which is called a station broadcast pattern. To do.

A pattern number (which is called an area code) is attached to this broadcast pattern, and this is stored in the device as data. By notifying the user of the area (city, town, village) and the area code where the radio waves transmitted from each station can be received, the user can input the area code to the device at the time of channel presetting and the device will be Based on the area code, the stored broadcast pattern is read out and automatically set to the channel position of the device.

In this method, since the broadcasting station name (channel position) is added to the stored data, the broadcasting channel of each broadcasting station can be set to the intended channel position, and the operation is very simple. That would be an advantage, but there would be a huge amount of material to inform users of the region names and codes that cover the entire country. Therefore, if the region of publication is limited, there is a drawback that the region that enjoys the desired advantages is limited.

[0014] For example, television broadcasting in England is E2.
The stations that are transmitted at frequencies in the range of 1 to E69ch and are broadcast there are currently BBC1, BBC2, ITV, CH4.
There are four stations and 1000 transmitting stations
Sent from.

By examining which of the 49 television broadcasting channels E21 to E69 are used to send four stations transmitted from 1000 stations, it can be classified into 175 broadcasting patterns.

The classified 175 types of pattern data (transmission channels of 4 broadcasting stations) are written in the ROM of the microcomputer. The pattern of 175 is the area code of 1 to 175.

To preset a channel, all you have to do is enter the area code of the station that can receive it.
These four stations can be set in order of BBC1, BBC2, ITV, and CH4 in the channel positions 1 to 4 according to the input area code. Therefore, in the channel selection device of the magnetic recording / reproducing apparatus having the built-in recording reservation function provided by GEMSTAR (LTD), after setting the channel position as described above, the channel position is set to correspond to each channel position. By setting the guide channel, the guide channel setting is also completed.

Therefore, if the automatic setting method of the regional broadcasting channel as described above is used, it is effective for improving the operability of the user.

However, in order to find and enter the area code corresponding to the receiving station from the 175 area codes, a manual describing 1000 stations and a pattern number (area code) matching the station is required. Become. Moreover, since there are 1000 stations, there is a problem that the station name to be received is not always known in advance where the user is.

[0020]

In the conventional automatic setting method of the regional broadcasting channel and the recording reservation apparatus using the same, it is necessary to input the regional code, and it is necessary to explain many regions and the corresponding regional codes. Therefore, many description pages are required to describe all of them in a manual or the like. There is also a problem that the user does not always know the area name (or station name) in which he / she is.

In view of the above problems, it is an object of the present invention to provide a method and apparatus for setting a regional broadcast channel that does not require the input of the regional code and therefore the description of the regional code. It is what

Is displayed.

Next, the automatic setting operation of the regional broadcast channel in the above recording reservation apparatus will be described with reference to the flowcharts of FIGS.

2 and 3, the automatic setting operation of the regional broadcast channel will be described by taking television broadcasting in the UK as an example.

In the United Kingdom, UHF E21ch (video carrier frequency 471.25 MHz) to E69ch (855.2).
4 broadcasting stations (B) with 49 broadcasting channels of 5 MHz
BC1, BB2, ITV, CH4) covers the whole of England with about 1000 stations.

When the broadcasting channels of four broadcasting stations transmitted by 1000 stations are examined, they can be classified into 175 kinds of broadcasting patterns, some of which are shown in Table 1.

[0052]

[Table 1] 2 and 3, by pressing the preset key, the preset mode is set (steps 21 and 2).
2). Next, auto search or manual search is selected, and auto is selected (step 23). As a result, auto search is performed with E2 having the lowest image carrier frequency.
Start from 1ch (step 24). When the first broadcast is found, the found broadcast channel is preset to the channel position 1 (steps 25 and 26), and when the next broadcast is searched, the operation is performed to preset to the channel position 2 and it is repeated until E69ch (step 27). ). Thereby, the positions 1 to 4 are sequentially preset in the order of reception.

In step 24, if no broadcast is found even after searching up to E69ch, a preset invalid (NG) warning is displayed and the preset mode is canceled (steps 28 to 30).

By the operation of the step 27, E69
After searching up to ch, the number of preset channel positions is checked (step 31). According to this check, if the number of broadcasts found by the auto search is not four (when the broadcast channels are print reset at positions 1 to 4 or more (step 32)), or the broadcast channels are preset at all four positions. If not (step 33)), it is determined that the reception result is irregular, and the process does not enter the automatic setting of the regional broadcasting channel, and the process proceeds to the GEMSTAR guide channel setting (step 34). The guide channel setting operation (method) will be described later.

If the result of the check in step 31 is that there are four broadcasts found by the automatic search (when the broadcast channel is preset only in the 1st to 4th positions (step 35)), the microcomputer of the device determines that the position 1
The broadcast pattern including the same channel as the channel set to is compared with many broadcast patterns stored in advance in the ROM of the microcomputer (step 36).

Table 2 is a list of broadcast patterns including E21 when the broadcast channel set in position 1 is E21ch.

[0057]

[Table 2] Here, there will be described two cases in which the patterns of the broadcast channels preset in the 1st to 4th positions are Example 1 shown in Table 3 and Example 2 shown in Table 4.

Example 1 shows an example in which the total number of broadcast channels preset to 1 to 4 positions by auto search is 106.

[0059]

[Table 3] Example 2 shows an example in which the total number of broadcast channels preset to 1 to 4 positions is 103 in the automatic search.

[0060]

[Table 4] Next, a broadcast pattern including a channel preset in one position is searched from the 175 patterns in the ROM, and BBC1 to CH for each of the found patterns.
The total number of channels up to 4 is compared with the total number of channels preset in positions 1 to 4 to search for a matching broadcast pattern (step 37).

As shown in Table 2, there are eight broadcast patterns including 21 channels. Among them, No2 is the only pattern in which the total number of channels in Example 1 is 106. In addition, the patterns in which the total number of channels in example 2 is 103 are No1, 3,
There are six patterns 13, 14, 21, 23 (step 38).

Then, it is judged whether or not there is only one pattern in the ROM which matches the total of the channels in the 1st to 4th positions (step 39).

Here, the case where there is only one pattern that coincides with the total of the channels in the 1st to 4th positions is the case of the example 1.

First, the case where the pattern of the broadcast channel preset in the 1st to 4th positions is the case of Example 1 will be described.

The E21ch is preset in one position, and the total number of channels preset in the first to fourth positions is 106. Since the total number of channels preset in the 1st to 4th positions is 106, the total number of channels of pattern 2 is 106 when compared with Table 2.

Therefore, in the case of Example 1, the broadcast pattern of the station transmitting the broadcast received by the automatic search is
It can be seen that it is pattern 2 (step 40).

To carry out timer reservation by GEMSTAR, set BBC1 to 1 position,
BBC2 in 2 position, ITV in 3 position,
I want to set CH4 to 4 positions, but I do not know which broadcasting station is set to 1 to 4 positions for the broadcasting channel preset by the search.

On the other hand, since the broadcast channel of pattern 2 stored in the device is linked to the broadcast station name (that is, corresponding to the channel position of the device), the broadcast channel data of pattern 2 is used to enter the channel position. The channel preset is automatically redone (recombined) (step 41) to complete presetting of the desired broadcast at the desired position and complete automatic setting of the regional broadcast channel (step 42). At this time, the automatic setting confirmation screen is displayed and the process ends.

Next, the case where the pattern of the broadcast channel preset to the 1st to 4th positions in step 36 is the example 2 will be described.

Example 2 is an example in which the total number of broadcast channels received by auto search is 103. In this case, E21c
Table 2 shows the broadcast patterns in which the total number of broadcasts including h is 103.
As shown in FIG. 6, there are six stations, and a plurality of stations exist for each pattern (station 43). Therefore, in this case, the transmission pattern of the received broadcast cannot be immediately specified.

At this time, the channel data on the 1st to 4th positions in the order of the number of stations to be transmitted in the candidate broadcast pattern are automatically rearranged by the previously stored pattern, and the confirmation screen is displayed (step 44). .

The user receives the automatically re-preset broadcast, and the user judges whether the preset broadcast matches the broadcast in the area (step 45). If they match, the position is rearranged. The data is confirmed (step 46), and the process ends.

If it does not match the broadcast of the area in step 45, it is judged whether or not there is a next broadcast pattern (step 47), and if there is no corresponding pattern, the GEMSTAR guide channel of step 34. Move on to settings. If there is the next applicable pattern in step 47, a confirmation screen is displayed with the pattern with the next largest number of stations (step 48), and it is judged again whether or not it matches the broadcast of the area in step 45, and it is determined that they match. If so, the broadcast pattern is confirmed (step 46), and the process ends.

As described above, in the UK example, 175 pattern data are written in the ROM of the microcomputer. VT without presetting the area code to preset
It is characterized in that an automatic search is performed at the location where a receiving device such as R is used and the received broadcast channel is once preset to the channel position of the device.

The auto-search starts from the low frequency broadcast channel (E21ch) to the final E69ch, and the received broadcast channels are sequentially preset from position 1 to positions 1 to 4.

The preset corresponding to the guide channel setting of GEMSTAR must be set from channel position 1 to BBC1, BBC2, ITV, and CH4, but in the automatic search, it is simply preset from the low frequency channel. Therefore, since it does not match the guide channel setting, it is necessary to change the order of the broadcast channels set for the channel positions.

Here, the microcomputer sees the channel set in position 1, and it is assumed that it is the E21 channel. E21c in position 1 of 175 patterns
The pattern including h can be narrowed down to eight as shown in Table 2. Further, the broadcast channels preset in the positions 1 to 4 by the automatic search are totaled and compared with the total value of the narrowed broadcast channels BBC1 to CH4 of the eight patterns. This allows the microcomputer to know the pattern of the broadcast channel transmitted from the station corresponding to the broadcast received by the auto search.

As described above, since the broadcast pattern of the area can be known from the received broadcast channel, the preset can be automatically redone with the channel data of the broadcast pattern stored in advance in the ROM. ) The preset matching the guide channel settings in) is automatically completed. Therefore, it is not necessary to search for the area code from many areas in the instruction manual, etc. and enter it.
000 stations and pattern numbers (region codes) matching them are not required), and a method and apparatus for setting a regional broadcast channel with improved operability can be realized.

In the embodiment described above, the preset broadcast channel is collated with the broadcast channel pattern in the regional broadcast channel pattern information storage means to identify the preset broadcast channel pattern and perform the presetting again. However, the preset broadcast channel may be matched with the data in the regional broadcast channel pattern information storage means to identify the region itself. If the region can be identified, it is easy to derive the region code from it. The necessary presetting can be automatically performed by using the conventional device of the area code input method.

In each of the embodiments described above, if the received broadcast channel is preset to the position to be preset in the first preset, re-presetting is naturally unnecessary.

Next, the reservation operation of the above recording reservation apparatus will be described with reference to the drawings. 4 is a flowchart showing a guide channel setting operation in the recording reservation apparatus of FIG. 1, and FIG. 5 is a view showing a guide channel setting screen in the recording reservation apparatus of FIG.

Prior to the setting operation of the guide channel, a desired broadcasting station is preset in the channel position of the channel selection means 1 by the above-mentioned preset operation. In the guide channel setting operation, as shown in FIG. 4, the guide channel is input (step 101), and then the channel position corresponding to the guide channel is input (step 102). When setting the guide channel and the channel position, as shown in FIG. 5, the guide channel (GUIDE CH.) And the channel position (TV CH.) Of the channel selection means 1 to which the guide channel is assigned are displayed on the screen. For example, if the broadcasting station of E21 is preset at position 1 of the channel selection means 1, when "21" is input by the guide channel input means 5, "21" is displayed at the position of GUIDE CH. Is set. Next, the position "1" is input by the channel position input means 3, and "1" is set at the position of TV CH.

After the input of the guide channel and the channel position is completed, the guide channel "21" and the corresponding position "1" are stored in the guide channel information storage means 8 (step 103), and the guide channel setting operation is completed. To do.

Next, the G code reservation processing operation in the recording reservation apparatus of FIG. 1 will be described with reference to the drawings. FIG. 6 is a flowchart showing the reservation processing operation by the G code.

First, the G code is the G code reservation setting means 4
Is input (step 201). The inputted G code is given to the microcomputer 7, and the microcomputer 7 decodes the G code (step 20).
2).

By decoding the G code, the guide channel and date / time information are obtained, and whether or not the corresponding guide channel and the corresponding channel position are stored in the guide channel information storage means 8, that is, the guide channel It is determined whether or not the setting is made (step 203). When the corresponding guide channel is set, the channel position corresponding to the same guide channel stored in the guide channel information storage means 8 is read, and this channel position is displayed on the screen as reservation data together with the date / time information ( In step 204, the reservation data is further stored in the timer reservation information storage means 9 (step 20).
5). After storing the reservation data, the G code reservation process is completed.

On the other hand, when the corresponding guide channel is not set, it is displayed on the screen that the guide channel is not set (step 206), and the G code reservation processing is completed without setting the reservation data. To do.

[0088]

As described above, according to the area broadcasting channel setting method and apparatus of the present invention, the channel position of the channel selection means is preset by the automatic search, and the broadcasting channel of the area. Since the receiving channel is automatically re-set to the channel position according to the pattern of, the automatic setting of the regional broadcasting channel can be performed without using the regional code, and therefore the guide channel setting operation can be done easily. It can be reduced and the operability of the user can be improved.
