Description

  The present invention relates to a broadcast receiving apparatus and a broadcast reception display method for displaying character information of a broadcasting station.

  In recent years, a technique of incorporating a TV tuner in a mobile phone is known (for example, see Patent Document 1). In terrestrial digital broadcasting or satellite digital broadcasting, broadcasting using a transmission band of 1 or 3 segments is scheduled mainly for small portable receivers with high portability.

  Also, in the television channel setting, the reception area is specified by inputting the region information, and the user can perform the setting operation by setting the channel setting and the direct tuning key setting with the recommended channel setting information of the region. A television setting method for assisting television is known (see, for example, Patent Document 2).

There is also known a television receiver that can set a broadcasting station of the same series as a broadcasting station in the original receiving area in the same memory area (direct key) even if the receiving area changes (see, for example, Patent Document 3). ).
JP 2000-9920 A JP-A-9-172581 JP 2003-179823 A

  By the way, when the television setting method is applied to a mobile broadcast receiver such as a mobile phone, the reception area changes with the movement of the device, unlike a broadcast receiver with a fixed installation position for home use, etc. Each time the reception area changes, the area information must be entered and a new reception channel must be set in the direct key. At that time, if regional information is entered, the channel setting (preset setting) recommended for the new region will be set, so the broadcasting station of the same series as the broadcasting station of the original region is set to the same direct key as the original region. Not necessarily. For this reason, the user (user) needs to get used to setting a new region.

In particular, when using in a different area from the area where you normally use it, the channel number and name of the broadcasting station may be different, so the channel where the user wants to broadcast the desired program based on the series information. Will be selected.
However, this series information is not displayed on the channel selection screen.

  The problem to be solved by the present invention is to provide a broadcast receiving apparatus that is easy for the user to use.

  The broadcast receiving apparatus according to the present invention has storage means for storing character information related to a broadcast station set to a channel number, and, when the broadcast area is changed, the broadcast station series information and the area change before the area change. When displaying the channel number of the broadcasting station set by inheriting and setting the channel number of the same broadcasting station based on the series information of the subsequent broadcasting station, and the setting unit inheriting and setting by the setting unit, Display means for displaying character information related to the pre-inherited broadcast station stored in the storage means.

In the present invention, preferably, the display means displays character information related to the succeeding broadcast station stored in the storage means.
In the present invention, preferably, the display means does not display the character information related to the pre-inherited broadcast station when the character information related to the pre-inherited broadcast station and the character information related to the post-inherited broadcast station are the same.
In the present invention, preferably, the storage means stores character information of a key station related to a broadcasting station set to a channel number, and the display means is set to a channel number stored in the storage means. The character information of the key station related to the broadcast station is displayed.

  The broadcast reception display method according to the present invention stores character information related to a broadcasting station set to a channel number, and when the broadcasting area is changed, the broadcasting station series information before the area change and the area after the area change are changed. Based on the broadcast station sequence information, the sequence inherits and sets the channel number of the same broadcast station, and when displaying the inherited and set channel number of the broadcast station, the stored pre-inheritance channel number is displayed. Character information related to the broadcasting station is displayed.

  The broadcast receiving apparatus of the present invention has an advantage that it is easy for the user to use.

The present invention is widely applicable when a broadcast receiving function is added to a mobile device that can move freely, such as a computer, a mobile phone, a game machine, a camera, a car navigation system, or a moving image playback device.
Hereinafter, embodiments of the present invention will be described using a mobile phone having a broadcast receiving function as an example.

FIG. 1 is a block diagram showing a basic configuration of a mobile phone according to the present embodiment.
As shown in FIG. 1, a signal (OFDM modulated signal) superimposed on a broadcast radio wave transmitted from a radio tower 100A of a broadcast station (or relay) installed in each reception area is transmitted to a broadcast receiver (mobile phone). ) 1 antenna 4 receives. The broadcast radio wave includes broadcast signals of a plurality of broadcast stations for each frequency band (channel). As will be described later, the broadcast receiving apparatus 1 selects one broadcast station from the radio wave by direct channel selection or scroll channel selection. The radio signal from the selected broadcasting station is demodulated to reproduce a video signal and an audio signal. In digital broadcasting, for example, the frequency range is defined as UHF 13 ch to 62 ch (470 MHz to 770 MHz), and the number of channels is 49 ch.

The mobile phone 1 has, as a basic configuration for broadcast reception and data communication, an antenna 2 for receiving radio waves for data communication (and telephone calls), wireless communication means (means including modulation and demodulation, and other signal processing circuits). 3. Broadcast receiving means (means including demodulation and other signal processing circuits) 5, channel selecting means 6, output means 7 including display means 7A and driving means (driving circuit) 7B, scroll selection such as a cross key It has station input means 8A, direct channel selection input means 8B such as a numeric keypad. These means are controlled by a control means such as a CPU.
The broadcast receiving antenna 4 and the antenna 2 for data communication and telephone call can be shared. The output means 7 includes sound output means such as a speaker.

  When broadcast radio waves are input to the antenna 4 from the radio tower 100A such as a broadcast station, the broadcast receiving means 5 converts the frequency and demodulates the broadcast signal from the lower frequency signal after the conversion. At that time, the signal of the specific frequency range (channel selected) specified by the user is demodulated by the scroll channel selection input unit 8A or the direct channel selection input unit 8B by the function of the channel channel selection unit 6, and the video of the channel is selected. The signal and the audio signal are input to the driving unit 7B and output (reproduced) by the display unit 7A and a speaker (not shown).

Prior to this reception and playback, the user needs to set the reception channel of the broadcasting station in advance, and display channel setting items on the display means 7A to display regional channel information (region name, region code, region number, city). Enter the area code.
The regional channel information needs to be changed for each viewing area. Generally, at the time of purchase, information on the purchased area and information on the Tokyo metropolitan area are often preset as defaults. Therefore, when changing a region different from the preset or a region once set, it is necessary to reset information of a new region according to the region.

In order to eliminate this operation, the broadcast receiving apparatus 1 according to the present embodiment has a broadcast receiving function added to a mobile device in particular, so that information on broadcasting stations in the location area is eliminated so as to eliminate the setting of the area. Is automatically acquired, and a function for automatically setting regional channel information based on the acquired information is provided.
As a configuration for realizing the function, as shown in FIG. 1, the mobile phone 1 includes an area-specific broadcasting station acquisition unit 11, a channel allocation unit 12, an area channel information storage unit 13 that acquires information about broadcasting stations in the area. User channel information storage means 14, channel selection channel information storage means 15, user channel update means 16 and character priority determination means 18 are provided. These units are also controlled by a control unit such as a CPU.

Of these, three storage means, that is, the regional channel information storage means 13, the user channel information storage means 14, and the channel selection channel information storage means 15, when these are provided as independent memory devices, The form is arbitrary, when dividing | segmenting and implement | achieving or when utilizing a part of existing memory or microcomputer built-in memory.
The regional broadcast station acquisition means 11, the channel assignment means 12, the user channel update means 16, the channel selection means 6 and the like described above may be realized as hardware, or the function of the program in the control means May be realized by software.

FIG. 2 shows a configuration example of channel information stored in the regional channel information storage unit 13, the user channel information storage unit 14, and the channel selection channel information storage unit 15.
The “channel number” in FIG. 2 represents a number used when the broadcast receiving apparatus of this embodiment selects a channel. Further, it may be used as a display channel number displayed on the display means. For the channel number i (i = 1 to N), the broadcast station name i in the current area (local area), the character (image) information i representing the broadcast station in the area, the time information i, Series information i, sequence broadcast station character image information (sequence character) i, previous broadcast station name group i, previous character information group i, and previous time information group i are stored in association with each other by an address or the like. Although not specifically shown, the selection information i is also stored in association with the channel number.

Here, the “time information” is an elapsed time stored in the user channel information storage unit 14 measured by a timing unit in the control unit (CPU or the like).
“Affiliate information” refers to the name of a higher affiliate broadcast station (key station) that broadcasts (distributes) a program or the like to a local broadcast station or identification information thereof.
The “previous broadcast station name group” is a set of broadcast station names in an area (previous place) where the mobile phone 1 existed before this place.
The “previous character information group” is a set of character images representing the broadcast station in the foreground.
The “previous time information group” is a set of time information in the foreground.
“Selection information” is information indicating whether the channel can be selected in channel switching or whether the channel is skipped (“skip”) when channel switching is performed. In the selection information, all the channels are “permitted (selectable)” by default, and the user sets “not permitted” or is based on the selection information setting of each channel included in the regional channel information. Basically, in the regional channel information, a channel that does not have a corresponding broadcasting station in the region is set as “disallowed”.

  Further, the information on affiliated stations can be obtained, for example, when the broadcast receiving means 5 shown in FIG. 1 acquires a BIT (Broadcast Information Table) included in a data stream defined by the digital broadcast standard. When the character image of the affiliated station cannot be obtained from the BIT, as will be described later, it is also possible to acquire the character image via the network 101 by wireless data communication.

  For each local reception channel, the regional channel information storage means 13 includes the name of the local broadcasting station, the character image representing the local broadcasting station, and the name of the broadcasting station to which the local broadcasting station belongs (the affiliated broadcasting station). Name), a character image representing the affiliated broadcasting station is stored.

  The user channel information storage means 14 stores channel setting information (such as correspondence between reception channels and channel numbers) when the user makes manual (customization) settings, the broadcast station name corresponding to the set reception channel, and the broadcast station name. Series information, affiliated broadcast station name, character image of affiliated broadcast station, previous broadcast station name (previous broadcast station name group), character image representing previous broadcast station (previous character information group), local time information Foreground time information (previous time information group) and selection information are stored.

  Note that manual (customized) channel setting performed by the user means setting a reception channel not included in the regional channel information, changing the correspondence between the reception channel and the channel number based on the regional channel information, or specifying a specific channel. In this example, information based on channel settings manually performed by the user is referred to as “user channel information”.

The channel selection channel information storage unit 15 stores channel information (channel selection channel information) generated from each storage information of the user channel information storage unit 14 and the local channel information storage unit 13 of the location area (local area). The channel selection channel information is generated by the channel allocation means 12. For each channel number assigned by the channel assignment means 12, the channel selection channel information storage means 15 includes a local broadcast station name, a local character image, series information, a series broadcast station name, a character image of the affiliate broadcast station, Stores local broadcast station name (previous broadcast station name group), character image representing previous broadcast station (previous character information group), local time information, previous time information (previous time information group), and selection information To do.
Note that the channel selection channel information can be shared by transmitting and receiving to / from other devices via the external information input / output means 17 such as infrared rays, short-range wireless, or memory card. In addition, after sharing information, one device can be used as a remote control for the other device.

When it is detected that the area has changed, the area-specific broadcast station acquisition means 11 issues a transmission request for information regarding the broadcast station in the area from the antenna 2 to the base station 100B using the data communication transmission path. This request signal includes a server for managing a local broadcast station character image information database 102 via a network 101 such as the Internet, a server for managing an affiliated broadcast station database 103, and a database of local independent stations not belonging to the affiliated group. (Not shown) are collectively sent to a server for managing. These servers permit the request, and broadcast receiving apparatus 1 sends information on the broadcasting station and the broadcasting station in the area including the character image (hereinafter referred to as regional channel information) via the data communication transmission path. Send to. The transmitted data communication signal is received by the antenna 2, demodulated by the wireless communication unit 3, and stored in the regional channel information storage unit 13 as regional channel information. The regional channel information may be received via the broadcast receiving means 5.
In order to detect the change of the area, a method of determining the area by the area information included in the broadcast wave, a method of determining the area by periodically acquiring electronic information program data, the electric field strength of the radio wave or the frequency band There is a method of monitoring the change, or a method of using a function for detecting a position by GPS or the like.
In addition, since this example is a mobile phone, regional channel information is acquired using a data communication function. If this function is not available, a database of regional channel information for the whole country is built in, or external information is stored. The input / output means 17, for example, infrared communication, short-range wireless, or a memory card slot and reading circuit may be used.

  The channel allocating unit 12 reads user channel information from the user channel information storage unit 14 and reads out the regional channel information from the regional channel information storage unit 13 every time the region changes or periodically, and reflects both. Set (generate) station channel information. The channel selection channel information is stored in the channel selection channel information storage means 15.

Here, an example of generation of channel selection channel information when the region changes will be described. For example, in a state where the user channel information storage unit 14 stores the first broadcasting station, the regional channel information corresponding to the changed area stored in the regional channel information storage unit 13 is the series of the first broadcasting station. 2 is assigned to the channel number for which the first broadcasting station is set based on the user channel information. In other words, the local channel information broadcasting station is set based on the user channel information. For this reason, in the channel selection channel information after the change, the affiliated broadcast station, the character image of the affiliated broadcast station, and the like are inherited by the channel number originally used by the user.
For broadcast stations that do not have affiliated broadcast stations that match the user channel information, the settings are set as they are based on the regional channel information. In setting, the channel number of the user channel information is set with priority, and when it overlaps with this, it is replaced with an unused channel number.
The channel number referred to here is an apparent number viewed from the user, and is different from the numbers 1 to 49ch used when assigning frequency bands.

  As other roles, the channel allocating means 12 controls the selection information when there is no broadcasting station corresponding to the channel number, and reflects the change of the channel number by the user operation in the selected channel information. That is, the channel allocation means 12 collates the storage contents of the regional channel information storage means 13, the storage contents of the user channel information storage means 14, and the storage contents of the channel selection channel information storage means 15, When there is no broadcasting station corresponding to the number, the selection information regarding the channel number is changed from “permitted” to “not permitted (skip)”.

  Further, the channel assignment unit 12 receives a change instruction via the control unit when a change in channel number or a change in channel selection information is instructed by the user operation from the operation unit 8, and these changes are received as channel selection channel information. And reflected in user channel information. When the channel selection information is changed by the user, when the information from the channel selection channel information storage unit 15 is read by the channel channel selection unit 6, the “permission” of the selection information is set according to the operation from the user. Or “not permitted (skip)” may be set by the channel selecting means 6. In that case, it is necessary to reflect the change by this setting in the stored contents of the channel selection channel information storage means 15 and the user channel information storage means 14.

  The user channel update unit 16 stores the information stored in the channel selection channel information storage unit 15 in the user channel information storage in order to reflect information related to the location in the user channel information when a certain condition is satisfied after the channel selection channel is generated. Copy to means 14. Here, the certain condition is, for example, that the staying time in the area exceeds a predetermined time, or that the channel setting has been changed by the user operation regardless of the staying time (for example, an instruction to change the channel number or selection information). And so on.

The staying time can also be monitored by changes in radio wave intensity, program guide, and the like. However, since the time information is held in this embodiment, the channel allocating means 12 (or control means) monitors this time information, and if there are many channel changes in a short time, the user plans a long stay. Therefore, it can be considered that the desired channel setting is performed. The time information does not necessarily need to be the actual elapsed time, and the time (year / month / day, and time if necessary) when the user channel information is changed can be held as the start time. This start time is reset every time the user channel information is changed.
The reason why this method is practically sufficient is that a control means (CPU) (not shown) usually has a time measuring means, so that the elapsed time can be calculated immediately if the start time is known. Maintaining the start time has the advantage of requiring less memory capacity.

  In this embodiment, “fixing” is introduced as a concept related to the staying time. “Fixing” can be estimated from the start time and the frequency of user operations for channel setting, and this is called “fixing” determination. Details of the “fixing” determination will be described later.

When the channel selection channel is generated or the user channel is updated, the character image of the channel selection channel information or the user channel information may be rewritten. In this example, the character image is not rewritten and accumulated as history information. At this time, the number of character images to be accumulated can be limited. For example, when new character images are added and stored, the oldest one is deleted.
Moreover, priority is provided when displaying the character image. This priority is determined by the character priority determination means 18 shown in FIG.

  The user can arbitrarily change the channel number assignment by selecting the channel setting change mode (the mode in which the user manually sets the channel) and operating the operation means 8. When this operation is performed, the changed information is reflected in the stored information in the user channel information storage means 14 and the channel selection channel information storage means 15, and thereafter, unless the changed channel number is changed again, the user Will be inherited as the channel number of the affiliated station you want to use in the future.

The channel selection channel information generated and changed in this way is read from the channel selection channel information storage unit 15 to the output unit 7 when the user views the broadcast, and is displayed on the display unit 7A as a channel selection screen.
When the user who sees the channel selection screen selects one channel, the channel selection unit 6 selects a target channel by adjusting the reception frequency of the broadcast reception unit 5 to the frequency band corresponding to the selected channel. Then, the broadcast content of the channel is displayed on the display means 7A.

The priority of which character image is displayed when the display unit 7A displays the channel selection screen is determined in advance by the character priority determination unit 18. The character priority determination means 18 includes a character image group stored in the user channel information storage means 14 and a character image group stored in the regional channel information storage means 13 (reflected in the channel selection channel information storage means 15). Thereafter, the priority of the character images is determined with the character image group stored in the channel selection channel information storage means 15. Then, the channel selection screen is created according to the determined priority.
Details of conditions for determining the priority will be described later.

FIG. 3 is a flowchart showing a processing flow for channel assignment. Hereinafter, the processing flow will be described with reference to FIGS. 1 and 3. In FIG. 3, “channel” is abbreviated as “CH”.
In step S1, the change of the broadcast area is constantly monitored. If it is determined that the broadcast area has changed ("Yes"), the process proceeds to the next step S2, and if there is no change in the broadcast area ("No"), the determination in step S1 is "Yes" at predetermined time intervals. Repeat until.

  In step S2, the regional broadcast station acquisition unit 11 shown in FIG. 1 acquires new regional channel information (regional CH information) from the digital broadcast supplementary information or the network 101 via the broadcast reception unit 5 or the wireless communication unit 3. The regional channel information is stored in the regional channel information storage means 13. At this time, old information is deleted and new information is stored. If regional channel information is stored in advance, this step may be omitted.

  In step S <b> 3, the channel assignment unit 12 compares the sequence information of the regional channel information newly stored in the regional channel information storage unit 13 with the sequence information in the user channel information storage unit 14.

  The reception channel of the regional channel information that matches the sequence information included in the user channel information is inherited and assigned to the corresponding channel number based on the user channel information, and stored in the selected channel information. In addition, the broadcast station name, series information, character image, and selection information corresponding to the assigned reception channel are stored in the channel selection channel information (steps S4 and S5).

On the other hand, the reception channel of the regional channel information that does not match the sequence information included in the user channel information is “Yes” in step S3, and the processing flow skips to step S6.
In step S6, it is determined whether or not all the regional channel information (regional CH information) has been confirmed. If this determination is “Yes”, the process proceeds to the next step S7, and if “No”, the process flow returns to step S3. Steps S <b> 3 to S <b> 5 are repeated until confirmation of all reception channels of regional channel information is completed. That is, by repeating these steps S3 to S5, broadcast stations that match the user channel information are allocated.

In step S7, it is confirmed whether the channel allocating unit 12 shown in FIG. 1 has registered all the reception channels of the regional channel information in the channel selection channel information storage unit 15. This process is for performing a process when there is a broadcast station that does not match the user channel information. If all the reception channels of the user channel information and the regional channel information match, the determination in step S7 is “Yes”, and the entire processing flow ends.
On the other hand, if there is a broadcast station that does not match the user channel information, the determination in step S7 is “No”, so the processing flow proceeds to the next step S8.

In step S8, the channel allocating unit 12 shown in FIG. 1 checks whether the channel number (based on the regional channel information) corresponding to the searched unregistered reception channel is unused in the channel selection channel information storage unit 15. Investigate.
If it is not used, in step S10, the channel allocating unit 12 reads out information related to the broadcasting station (channel number, broadcasting station name, character image and selection information of the broadcasting station) from the regional channel information storage unit 13, and selects the channel. Registration is performed by storing in the channel information storage means 15.
If the channel number corresponding to the searched unregistered reception channel (broadcast station) is already used in the user channel information, the determination in step S8 is “No”. Therefore, in the next step S9, it is confirmed whether or not the channel number stored in the channel selection channel information storage means 15 is still free (unregistered). If the result of this confirmation is “Yes”, in step S11, the channel selection channel information storage means 15 registers information relating to the broadcast station in an unset channel number.
If the determination in step S9 is “No”, since there is no channel number to be registered, the registration process is skipped, the process returns to step S7, and the subsequent processes are repeated.
If there is no vacancy (unregistered) in the channel number stored in the channel selection channel information storage means 15, the user selects which channel number to register the unregistered reception channel (broadcast station). It may be registered forcibly according to a predetermined setting (for example, according to the channel number order or regional channel information setting), or notification to that effect (display, sound output, etc.) without registration at all ) May be performed.

FIG. 4 is an explanatory diagram showing an example of transition of channel selection channel information accompanying user movement. Hereinafter, a transition example related to a specific reception channel A in the channel selection channel information will be described with reference to FIGS. 1 and 4.
The area A shown in FIG. 4 is set as an area serving as a user's reference (for example, an area of a living base), and the user stores the reception channel A in the user channel information storage unit 14 in association with a certain channel number based on this area. ing. When the user is in the area A, the reception channel A stored in the user channel information storage unit 14 matches the reception channel A of the area channel information of the area A. Therefore, when the above-described channel allocation processing shown in FIG. 3 is performed, user channel (CH) information is obtained as shown in FIG. 1 of area A shown in FIG. 4 (numbers in the table are represented by numbers surrounded by circles). The channel number corresponding to the stored reception channel A is assigned the reception channel A of the regional channel (CH) information, and the channel selection channel information is generated (in FIG. 1, this information is represented by “A”). ing).

  When the user moves from area A to area C, the information in user channel information storage means 14 corresponds to area A, whereas the information in regional channel information storage means 13 corresponds to area C. . Therefore, channel selection channel information for the user to select a channel in area C is constructed while the reception channel C of the same affiliated station as the reception channel A included in the regional channel information inherits the channel number. Hereinafter, this information is referred to as “CH information for inheriting channel information of a certain channel number set in area A and selecting a broadcasting station of the same channel number with the same channel number in area C”. (C) ”. In this case, as shown in the chart 2 of the area C shown in FIG. 4, the user CH information remains “A”, but the regional CH information is changed from “A” to “C”. The information is rewritten from “A” to “A (C)”.

  Next, when the user moves from the area C to the area B, the channel selection CH information “A” for selecting a channel in the area B by inheriting the sequence information of a certain channel number set in the area A as in the previous area C. (B) "is constructed. In this case, as shown in the chart 3 of the area B shown in FIG. 4, the user CH information remains “A”, but the regional CH information is changed from “C” to “B”. The reception channel B (broadcast station) is set, and the channel selection CH information is rewritten from “A (C)” to “A (B)”.

  Next, when the user returns from the area B to the area A again, the region CH information returns to “A” used by the original user, and as a result, the state of Chart 1 shown in FIG. 4 is reproduced. The

  In the example of FIG. 4, the selection period by the user channel updating means 16 shown in FIG. 1 is because the stay period of the area C and the area B is short and the channel number is not intentionally changed by the user. The stored contents of the user channel information storage means 14 including the copy of the station CH information are not updated at all.

On the other hand, FIG. 5 shows transition of channel selection channel information when user channel information is updated in area C. In the following description of FIG. 5, the points different from FIG. 4 will be mainly described.
In the case of FIG. 5, by moving from area A to area C, CH information “A (C)” is selected for channel selection in area C by inheriting the sequence information of a certain channel number set in area A. This is the same as in the case of FIG.
In area C, it is assumed that the user CH information is updated when a predetermined time elapses or when the user intentionally changes the channel number. This is because the user channel update unit 16 shown in FIG. 1 copies the stored information in the channel selection channel information storage unit 15 to the user channel information storage unit 14 or the stored information in the user channel information storage unit 14 corresponds to the user operation. It is executed by changing the contents. The updated state of the user CH information is shown in FIG.

  Next, when the user moves from area C to area B, since the user CH information has already been updated to “A (C)” at this time, the series information of the updated user CH information “A (C)” And channel selection CH information “A (C (B))” for channel selection in area B is constructed. In this case, as shown in the chart 4 of the area B shown in FIG. 5, the user CH information is “A (C)”, and the regional CH information is changed from “C” to “B”. A reception channel B (broadcast station) of the same series based on (broadcast station) is set, and the channel selection CH information is rewritten from “A (C)” to “A (C (B))”.

Next, when the user returns from the area B to the area A again, since the user CH information has already been updated to “A (C)” at this time, the updated user CH information “A (C)”. The channel selection CH information “A (C (A))” for selecting the channel A in the area A is inherited. In this case, as shown in the chart 5 of the area A shown in FIG. 5, the user CH information is “A (C)”, and the regional CH information is changed from “B” to “A”. A reception channel A (broadcast station) of the same series based on (broadcast station) is set, and the channel selection CH information is rewritten from “A (C (B))” to “A (C (A))”. The channel selection CH information is different from the channel selection CH information “A” used by the original user, but reflects the update of the user CH information in the area C. Evolving into easy-to-use channel selection channel information.
That is, in FIG. 5, the reception channel C updated in the area C belongs to a plurality of series, for example, and includes an affiliated station of the reception channel A. However, if the representative series is different from the reception channel A, This channel number is inherited by the representative affiliated station (broadcast station) of the receiving channel C.
In the above example, one channel number is described as an example, but of course, the same applies to a plurality of channel numbers.

  4 and 5, the user's stay time in each area is monitored by the time measuring means in the control means of FIG. However, the criteria for determining the length of stay time for determining whether or not to update the user CH information is arbitrary. For example, the user channel is updated (copied) by setting a long time in the short-term travel mode and setting a short time in the long-term stay mode exceeding several months. Also, the user channel is updated when there is an intentional channel assignment by the user regardless of the length of stay. In any case, the user CH information is not updated in the example of FIG. 4, but the user CH information is updated in the area C in the example of FIG.

FIG. 4 assumes that, for example, when the user moves from a living base A across different broadcast areas for the purpose of entertainment, business trips, short-term trips, etc. In B, the broadcast in that area can be viewed, but since these are temporary passing or staying areas, there is no need to change the user CH information.
On the other hand, FIG. 5 assumes that area A is a living base, but if area C is also a second living base, area C is not a living base, but the actual usage of TV is mainly In these cases, it becomes easy to construct new user channel information while inheriting the user channel information used in the previous area.

As described above, in the present embodiment, when the user moves from the area A to be used as a reference, such as a living base, and returns to the area A again, tuning is performed in each area by assignment based on the channel configuration customized by the user. When returning to the area A, the channel configuration does not need to be restored to the customization state originally set by the user.
In each of the areas A and C, the information on stations that are not actually broadcast is automatically “not permitted” as described above, so that the user cannot perform scroll tuning. It does not impair convenience.

Next, FIG. 6 shows an example of the channel selection screen.
On the channel selection screen, the channel number assigned as channel selection channel information from the left, the character (image) representing the broadcasting station in the current area (local area), the name of the local broadcasting station, the area existing in the previous area (foreground area) A character (image) representing a broadcasting station and a character (image) representing a broadcasting station (key station) of a series are displayed. In this example, up to two characters (images) representing the broadcast station in the foreground can be displayed, but the number may be one or three or more. A thick frame line (channel selection bar) indicates the currently selected channel. The shaded channel indicates a channel to be skipped when selecting a scroll (skip recognition).

4 and 5 described above are based on the area A, but the channel selection screen shown in FIG. 6 is the channel selection displayed in the area C when moving from the area B in the order of the area A and the area C. Show the screen.
In this case, when searching for a program or the like regularly viewed in areas B and A in area C, the same user channel number is continued as long as it belongs to the same series. That is, in FIG. 6, channel numbers “1” and “7” to “13” correspond to channels for which the series information has been taken over, and other channel numbers are independent stations that perform national broadcasting or local broadcasting. Corresponds to the channel.

A character “c1” representing the local broadcasting station and a broadcasting station name “C1 broadcasting station” are assigned to the channel number “1”, and “b1” is a character representing the broadcasting station in the previous location on the right. "A1" followed by the character "z1" representing the broadcasting station (key station) of the affiliated group.
Even if the user does not know the broadcast station “C1”, the channel number “1” that has been used so far, the characters “b1” and “a1” representing the broadcast station, or continuously displayed even if the area changes. By looking at the character “z1” of the affiliated broadcast station (key station), it is possible to imagine an approximate broadcast program.

  Corresponding to the channel number “13”, the character “c6” representing the local broadcast station, the broadcast station name “C6 broadcast station”, and the affiliated broadcast station character “z6” are displayed. The broadcast station characters are not displayed. In this case, the channel is assigned to the broadcasting station for the first time, and in this case, the channel number “13” is displayed with the character “z6” representing the broadcasting station of the affiliated group. Channel selection is possible.

  On the other hand, since only the character “n1” representing the local broadcasting station and the broadcasting station name “N1 broadcasting station” are displayed corresponding to the channel number “3”, the broadcasting station (key) itself is displayed. Station).

As described above, on the channel selection screen in the present embodiment, a character representing a local broadcast station and a character representing an affiliated broadcast station can be displayed for a channel to be selected. Therefore, even if the user forgets the channel number when he / she goes to another area on a trip or the like, the user can see which channel he / she uses regularly by watching the character (to which broadcasting station (key station)) It is possible to know the broadcasting station to which it belongs. Furthermore, since the character representing the broadcasting station in the foreground that has been viewed until recently is displayed, even if the character of the broadcasting station (key station) of the affiliated group is forgotten, the information to be judged by the user increases, so that the channel selection is It becomes easy. In addition, since a plurality of foreground characters are displayed, the user can make an appropriate determination even if the user has moved from place to place.
In addition, since it is a character (symbol, icon, image, etc.), it can be displayed without taking up space in the case of a small display such as a mobile phone rather than displaying a large number of character strings. In addition, when there are a plurality of broadcasting stations that are affiliated, a plurality of characters may be displayed.

Next, a determination method of “fixing” and conditions for determining the priority of character display on the channel selection screen will be described.
FIG. 7 and FIG. 8 are tables showing example conditions for determining the priority of character display on the channel selection screen. FIG. 9 shows an example of the “fixing” determination method.
Hereinafter, “fixing” and its determination will be described first, and then the description will proceed to FIGS. 7 and 8.

  As will be described later, the concept of “fixing” is used in FIG. This is an index for deciding which character is displayed first (preferentially) in the character group representing the broadcast station in the foreground, for example.

  Regarding “fixing”, for example, “continuation time of user channel information as a local broadcasting station, that is, time when information of a certain channel is stored in the user channel information storage means 14 (see FIG. 1) (“ current time ”−“ When the “starting time”) reaches a certain time or more ”, it can be determined that the selection of the channel is“ fixed ”.

As another determination method of “fixing”, the method shown in FIG. 9 can be adopted.
In FIG. 9, the horizontal axis represents elapsed time, and the vertical axis represents the number of channel selection operations. The hatched area (B) in FIG. 9 is an area where “fixed” is determined.

Even if the elapsed time has passed, if the number of channel selection operations is too small, it is determined that the user is not used to the user. On the other hand, when the number of channel selection operations is large, it is determined that “fixed” even if the elapsed time is relatively short.
Even if time has passed, if it is not used as a channel selection operation, even if it is moved to another broadcast area and updated as user channel information, the information of the previous local broadcast station (local broadcast station) Is not familiar (remember). Rather, it is easier for the user to familiarize new information quickly.
On the other hand, even if it is a short elapsed time, if the channel selection operation is performed at a high frequency, it is determined that the user is familiar (remembered) and used as information for estimating new information (previous) Although it is shown as a local broadcasting station), it is convenient for the user.
Note that when the method of FIG. 9 is applied to an actual system, for example, when the degree of familiarity is defined with the elapsed time and the number of channel selection operations as two parameters, the threshold is determined, and the threshold is exceeded. It can be determined that it has been “fixed”.

Next, FIGS. 7 and 8 will be described.
7 and 8 show five conditions for user channel (CH) information, and display contents and positions on the channel selection screen. Here, as shown in FIG. 6, the display position is divided into “left end”, “start”, “second”, and “right end” for each channel number. Among these positions, the “first” and “second” positions are positions where the type of character to be displayed is changed according to the priority. In addition, “head” is a position for displaying a character of a broadcasting station having a higher priority than “second”.

At the “left end”, a character representing the local broadcast station stored in the selected channel information and the name of the broadcast station are always displayed.
In addition, at the “right end”, a character representing an affiliated broadcasting station (key station) is always displayed. In this example, there may be a case where there is one affiliated broadcasting station and a plurality of affiliated broadcasting stations. However, in the case of one affiliated broadcasting station, the priority of the affiliated broadcasting station having the highest priority is “highest priority” for convenience. 7 and FIG. 8, the character representing the highest priority affiliated broadcast station (indicated as “highest priority (sequence)” in the figure) is always displayed at the “right end”.

“Condition 1” defines that the local broadcasting station is “same” or “different” between the user CH information and the regional CH information.
“Condition 2” specifies “one” or “two or more” for affiliated broadcast stations in the user CH information.
“Condition 3” specifies that “two or more”, “one”, or “none” is specified in the user CH information by the previous broadcast station.
“Condition 4” is based on “fixing” to determine whether or not it is steady for the user to select a local broadcast station based on the user CH information. If not (≠ “fixing”).
“Condition 5” defines whether or not the broadcasting station for regional CH information is a “key station”.

  Hereinafter, an example of character arrangement at the “first” and “second” positions will be described.

When “Condition 1” is “same”, the characters of the local broadcast station are not displayed at the “first” and “second” positions on the channel selection screen, and the previous or affiliated broadcast stations are not displayed at those positions. Displays the character.
“Condition 1” becomes “same”, and based on “Condition 2”, they are arranged from the left according to the priority and then right-justified.

When “Condition 1” is “Different”, the priority of the two characters representing the foreground and the local broadcasting station differs depending on whether or not “fixed”. That is, in the case of “fixed”, it is presumed that the user has often watched the program of the local broadcast station, and the local broadcast station character is displayed with priority over the previous broadcast station character.
Specifically, “condition 1” becomes “different”, and “condition 2” is taken into consideration, and display control is performed depending on whether “condition 4” is “fixing” or not “fixing”.

  In addition, as “condition 5”, it is also considered whether or not the broadcasting station of the regional channel is “key station”.

  In this character arrangement method, the priority of the user station information for the previous broadcasting station is determined based on the “fixed” state and the “newness”. First, in the “fixed” state, priority is given to the one that is “fixed”. Next, look at "newness" and give priority to new ones. That is, in the user channel information, for example, the newest broadcast station with the newest start time is set as “highest priority”, the new previous broadcast station is set as “next priority”, and thereafter, this “newness” is similarly set. This is the standard for determining priority.

In the character arrangement method of this example, the priorities of the previous broadcast station and the local broadcast station in the user channel information are determined in the order of “fixing” and “newness” in the same manner as described above. However, it is desirable that the priority of the local broadcasting station is not set to the third or higher (in the case of the third or higher, the priority is set to the second). As a result, when the user channel information has just been updated (the local broadcasting station is not “fixed”) and the user has visited a different broadcasting area for travel or the like, the local broadcasting station has a lower priority than the previous broadcasting station. This prevents display and increases the time that the user gets used to the local broadcasting station.
It is desirable that at least one broadcast station having the highest priority among the previous broadcast station or the local broadcast station is displayed.

FIG. 10 and FIG. 11 are diagrams specifically illustrating how the channel information of the user, the region, and the channel selection changes as the user moves.
In each area, the stored contents of the user channel information storage means 14 (see FIG. 1), the stored contents of the regional channel information storage means 13, and the stored contents of the channel selection channel information storage means 15 are shown in order from the left. Each stored content is, in order from the top, channel number, (local) broadcast station name, (local) character, time information, sequence information (including the broadcast station name), sequence character, previous (local) broadcast station name, previous (Ground) character, previous (ground) time information is shown.
A channel selection screen is shown next to the stored contents for each area.

  In this embodiment, independent broadcast stations such as national broadcasting and local independent broadcasting have (local) broadcast station names and series information matching, and (local) characters and series characters match. Although it is written as information in the series information and the series character area, it is not displayed. For this reason, in FIG. 10, the location of the channel selection channel information corresponding to this is blank, and the affiliated characters of such independent broadcast stations are not displayed.

FIG. 10 shows a state 1 in which the user is in the base area B (the state number is indicated by a circled number in the figure), a state 2 in which the user has moved from the area B to the area A, and user channel information State 3 in which the update has been performed is shown.
FIG. 11 shows a state 4 after moving from the area A to the area C, and a state 5 after returning to the area A as the base once and returning to the area C again after 5 years.
Hereinafter, the states 1 to 5 will be sequentially described.

<State 1>
In area B, the user channel information is the same as the regional channel information. For this reason, the channel selection channel information is the same as the user channel information. However, the time information is held only by the user channel information, and in the channel selection channel information, the redundant information is not displayed as described above.
As for the character on the channel selection screen, the local character is displayed at the “left end”, and the affiliated character is displayed at the “right end”.

<State 2>
In area A, of the regional channel information, the series information “N1” “Z1” “N2” “Z2” “Z3” of the channel numbers “4” “6” “8” “10” “12” is user channel information. Are the same as the series information corresponding to the channel numbers “3”, “1”, “5”, “7”, and “12”. For this reason, channel selection channel information is constructed in the following five processing steps.

  Processing Step 1: User channel numbers (channel numbers in user channel information) “1”, “3”, “5”, “7”, and “12” are inherited as channel numbers of channel selection channel information.

  Processing Step 2: User channel information series information “Z1” (“N1” is added to the channel selection channel information corresponding to each of the inherited user channel numbers “1”, “3”, “5”, “7”, and “12”. ”“ N2 ”)“ Z2 ”“ Z3 ”, series characters“ z1 ”(“ n1 ”“ n2 ”)“ z2 ”“ z3 ”are inherited.

  Processing step 3: Broadcast station names “A1” “N1” “N2” “A2” “A3” of regional channel information having the same series information as the user channel numbers “1” “3” “5” “7” “12” , Character images “a1”, “n1”, “n2”, “a2”, “a3” are channel selection channel information respectively corresponding to the inherited user channel numbers “1” “3” “5” “7” “12”. Copied in place.

  Although there is no channel channel information in this example, the regional channel information that is not assigned as a channel selection channel is registered as selected channel information as it is (processing step 4). If there is one in which the regional channel number has already been assigned as the channel selection channel, the information on the regional channel number is assigned to the unused channel selection channel number (processing step 5).

Through the above processing steps 1 to 3 (4, 5), “information B (A) for selecting area B with priority on area B” is constructed as channel selection channel information.
When this information is displayed, the local character is displayed at the “left end”, the affiliated character is displayed at the “right end”, and the foreground characters “b1” and “b2” are displayed at the “second”. “B4” is displayed.

<State 3>
In this example, user channel information is updated in area A. In this case, the update of the user channel information is not due to the change of the channel number but because a predetermined time has elapsed.
Then, the previously selected channel selection channel information B (A) is copied to the user channel information. In the case of this example, information regarding the broadcast station name “B3” that originally existed in the user channel information storage at this time remains, but these may be deleted. Further, since it is old information even if it is left, and it is not selected on the channel selection screen (scroll selection is not permitted), it is omitted in the channel selection channel information and the channel selection screen of FIG.

  The channel selection channel information is reconstructed based on the updated user channel information. As a result, information B (A) is set in both the user channel information storage unit 14 and the channel selection channel information storage unit 15. The information B (A) inherits the series information and user channel number of the first area B, changes the broadcast station name in association with them, and the characters “b1”, “b2”, “ b4 "is accumulated.

<State 4>
As shown in FIG. 11, in the area C, the channel information “N”, “N2”, “Z1”, “Z2” of the channel numbers “1”, “3”, “4”, “6”, “8”, “10” of the regional channel information. “Z3” and “Z4” are the same as the sequence information of the channel numbers “3”, “5”, “1”, “7”, “12”, and “10” of the user channel. Therefore, in processing step 1 similar to state 2 described above, these channel numbers are inherited as channel selection channel numbers, and information other than the local station name and local character is copied from the user channel information. (Processing step 2). The local broadcasting station name and the local character are copied from the regional channel information (processing step 3).

In the channel numbers of the remaining regional channel information, the channel number “13” is not assigned in the channel selection channel information B (A) in the state 3, so this channel number (“13”) is used as the channel selection channel number. The corresponding regional channel information is copied (registered) as channel selection channel information as it is (processing step 4).
On the other hand, the channel number “12” of the regional channel information is already assigned to another broadcast station in the channel selection channel information B (A) in the state 3, and is assigned to the channel number “2” that is not yet used. The relevant information is copied from the regional channel information (processing step 5).

Through the processing steps 1 to 5 described above, “information B (A (C)) for preferentially selecting information in area C with priority on information B (A)” is constructed as channel selection channel information.
When this information is displayed, the foreground characters “b1,” “b2,” and “b4” of the area B that is the base are displayed at the “first” on the channel selection screen, and the foreground of the area A is displayed at the “second”. Characters “a1”, “a2”, “a3”, and “a4” are displayed.

<State 5>
Assume that the user channel information is not updated during this period when the user once moved to area A and then moved again to area C after five years.
Channel selection channel information is constructed in the same manner as in the state 4 procedure.
However, there is a difference in the display of the channel selection screen between state 4 and state 5. In the channel selection screen (state 4) in area C five years ago, the foreground character in area B is displayed with priority over the foreground character in area A. On the other hand, in the channel selection screen in area C in state 5, the foreground character in area A is displayed with priority over the foreground character in area B. This is because the user channel information is updated within five years even if the broadcasting station in the area B, which is the base, was “fixed” five years ago and the broadcasting station in the area A was not “fixed” This is because the foreground characters in areas A and B are both stored in the user channel information storage means, and the broadcasting station in area A is “fixed”. In this case, the broadcast station in area A is “new” and has a higher priority than the broadcast station in area B. As a result, the priority order of the channel selection screen is reversed.

12 and 13 show other specific examples of the transition of channel information.
FIG. 12 shows the state 1 after 10 years in the base area B, the state B moved from the area B to the area A, updated the user channel information, the state 2 after 5 years, and the area A to the area C. It moves, updates the user channel information, and shows a state 3 after 7 years have passed.
FIG. 13 shows the state 4 after moving from the area C to the area D, updating the user channel information, and further passing four years, and the state 5 after moving from the area D to the area B.
Hereinafter, the states 1 to 5 will be described in order, but the construction of the channel selection channel information, the display of the channel selection screen, and the update of the user channel itself can be performed in the same manner as described above. Here, the transition of time information and priority determination based on the transition will be mainly described.

<State 1>
State 1 is after 10 years have passed since the user channel information was updated in area B. In this case, the time information in the local area of the user channel information is “10”. The channel selection screen is not different from the case of FIG.

<State 2>
State 2 is after moving to area A and updating user channel information after 5 years. In this case, the broadcast station in area B is registered as the previous broadcast station in the user channel information, and is displayed as the previous broadcast station on the channel selection screen.

<State 3>
State 3 is after 7 years have passed since moving to area C and updating the user channel information. In this case, in the user channel information, the broadcasting station in area A is shifted to the foreground broadcasting station, and the broadcasting station in area A is added as the foreground broadcasting station with high priority on the channel selection screen.

<State 4>
State 4 is after four years have passed since moving to area D and updating the user channel information. In this case, in the user channel information, the broadcasting station in area C is shifted to the previous broadcasting station.
Here, assuming that the number of predecessor broadcast stations held for user channel information is two per channel, there are three predecessor broadcast stations and no storage area. For this reason, the information with the lowest priority is deleted from the previous broadcasting stations. At this time, the priority determination depends on “fixing” and “time information (newness)”. Here, assuming that the threshold of “fixing” is 4 years or later, all the previous broadcasting stations are “fixed”. Next, judging from “newness”, the broadcasting station “B1” is the channel number “1”, the broadcasting station “B2” is the channel number “7”, and the broadcasting station “B4” is the oldest channel number “12”. For this reason, the information regarding the previous broadcasting stations “B1,” “B2,” “B4” is deleted. As a result, on the channel selection screen, the broadcasting station in area C is displayed as the top priority broadcasting station, and area A (partial area B) is displayed as the next priority broadcasting station.

<State 5>
State 5 is the situation after moving to area B. In this case, on the channel selection screen, the broadcasting station in area D is displayed as the top priority broadcasting station, and area C is displayed as the next priority broadcasting station.
When the channel selection screens in state 4 and state 5 are compared, the channel numbers “1”, “7”, and “12” related to the previously deleted broadcast stations “B1”, “B2”, and “B4” are the previous ones in the state 4 state. All positions where terrestrial broadcasting stations can be displayed are used. For this reason, it is understood that there is no inconvenience in display even if “B1”, “B2”, and “B4” having the lowest priority are continuously held.
In this way, if the information of the previous broadcast station that is no longer necessary according to the priority is deleted, it is possible to avoid compression of the memory area due to unnecessary information.

  Hereinafter, advantages of the present embodiment will be described.

  According to the present embodiment, the three information storage means shown in FIG. 1, that is, the regional channel information storage means 13, the user channel information storage means 14, and the channel selection channel information storage means 15, respectively, have regional channel information and user channel information. The channel selection channel information is stored. For this reason, when channel selection channel information is set (generated), regional channel information and user channel information are not deleted. Further, it is easy to copy the newly generated channel selection channel information as subsequent user channel information.

On the other hand, if the storage means (recording area) for regional channel information, user channel information, and channel selection channel information is shared, the following inconvenience may occur particularly when a user with a living base moves frequently. Is expensive.
First, if the data in the memory is rewritten for each movement, the channel of the area that was originally set becomes a vacant area when passing through an area where there is no affiliated broadcasting station during movement, and when returning from the destination to the base, A new channel may be set in this empty area. In this case, the user is forced to perform an operation to restore the channel setting.
Secondly, depending on the destination area, since a plurality of affiliated programs are broadcast to one affiliated broadcast station, the program intended by the user may be broadcasted by a broadcaster with a different affiliate.
Third, when moving from an area where a plurality of series programs are broadcast to one affiliate broadcasting station to an area where the programs are broadcast for each series, each series is not set at a memory location. In addition, the memory location of the base may not be restored.
Fourth, when there are a plurality of broadcasting stations of the same series in one area during movement, the broadcasting station set last may be registered, so that another broadcasting station generated during processing may not be selected. is there.

  If the scale of the shared memory area is increased in order to prevent the occurrence of the inconvenience, unnecessary memory space is consumed.

  In the present embodiment, since the size of the memory area necessary for storing the regional channel information, the user channel information, and the channel selection channel information can be optimized, the above-mentioned inconvenience is achieved while minimizing the overall memory area size. The advantage that the generation can be effectively prevented is obtained.

  According to the present embodiment, even when the user moves to a different broadcasting area for a short period of time, such as travel, the channel selection channel information is constructed in a form that inherits the familiar channel configuration without burdening the user. Therefore, the user can easily select a desired channel. Similarly, when a user frequently goes to and from a plurality of places or moves by moving, a channel can be constructed in a manner inheriting a familiar channel configuration without imposing a burden on the user.

  Further, the present embodiment has the following advantages regarding character display.

It is possible to acquire characters of affiliated broadcasting stations and present them from the beginning together with local broadcasting stations. For this reason, even if the broadcast area changes, it becomes easy for the user to know the series, so that (the user) can determine the local broadcast station related to the broadcast station that he / she sees on a daily basis.
In addition, by using the character indicating the foreground broadcast station and the character of the local broadcast station, it is possible to display necessary information even in a portable terminal having a small display screen area. Also, if you accumulate characters and display the required number of characters, even if you forget the channel number or series of character images that were originally used, the desired channel can be selected based on the new previous selected character in the memory. You can choose. In addition, the scroll selection “permit” and “non-permission” can be switched automatically or by user operation, so that the user can easily select a channel even on a channel selection screen reflecting information on a plurality of regions. There is no loss of sex.

  Since the priority of the broadcasting station suitable for the user is determined and the display position of the foreground character is changed based on this, the history of movement can be roughly estimated by viewing the foreground character from a position with a higher priority to a lower position. I can judge. Also, when determining the priority, the familiarity is determined from “fixed” and “newness” as the basic data, and the display order of the previous broadcast station is determined using this as the priority.

It may be difficult to determine the history of the broadcasting station selected by the user only with the time information (newness).
In the present embodiment, since the familiarity is generated in consideration of the frequency of the channel selection operation in addition to the time information, the channel selection operation is performed even when the time information (elapsed time stored as user channel information) is short. The familiarity (priority) rises if the frequency of is high. Therefore, especially for the user, even when the user has just moved to the area where he will be staying for a long time in the future, as long as the channel selection operation is frequently performed, information regarding the local broadcasting station is immediately reflected on the channel selection screen. It becomes possible.
In addition, in order to delete the previous broadcast station with low priority from familiarity level, the user is provided with meaningful information (information related to the previous broadcast station) without squeezing the memory associated with the user channel update. It becomes possible to do.
