Description

  The present invention creates the preference channel information created based on the viewing performance of the television viewer, and updates the preference channel information when the broadcast area where the television receiver is installed is changed, The reception channel is selected based on the updated preference channel information.

  In recent years, with the advancement of multi-channel broadcasting technology and the diversification of society, many broadcasting media such as CATV, satellite broadcasting, satellite communication broadcasting, etc. are used for broadcasting media, and many programs are available on abundant channels. It has come to be broadcast. There is a tendency that the number of operations when a television receiver selects and receives broadcast media and broadcast channels other than analog terrestrial broadcasts increases. The user operates the remote control button many times to view the program of the desired channel. Simplification of channel operation is required.

For example, Patent Document 1 discloses the following. In order to select a desired channel easily, quickly and reliably, the receiving apparatus generates and stores a channel selection list based on the viewing time indicated by the selected time of the broadcast channel that the user has viewed in the past. . The channel selection list is associated with the operation keys of the remote controller used for the receiving apparatus. A user realizes a function of easily selecting his / her favorite channel and viewing a program by operating a remote control key.
JP 2003-209755 A

  However, when the receiving device is moved outside the broadcast reception area, etc., even if a preferred broadcast channel is selected based on the channel selection list created before the movement, only noise is transmitted if the broadcast is not being performed on that channel. The function of selecting a favorite channel, such as receiving a message, is rather an obstacle. Unless the user himself / herself initializes the channel selection list, an operation based on the old history is performed.

  Therefore, it is necessary to clear the channel selection list, acquire data related to the broadcast channel selection time in the new broadcast reception area, and operate the favorite channel selection function based on the result. However, the clearing operation of the channel selection list by a dedicated operation cannot be easily performed when the instruction manual of the receiving device is stolen due to moving or the like.

  On the other hand, terrestrial digital broadcasting has started, and analog broadcasting channels have moved to frequencies that do not interfere with terrestrial digital broadcasting. This is commonly referred to as Anaana conversion. If the above-mentioned favorite channel is subject to analog-analog conversion and the channel in the channel selection list can be changed at the same time, the user's preference information accumulated up to that point can continue to be used.

  Therefore, the present invention detects when a received channel changes, and detects whether the detected change is due to a change in the reception area or a movement of the channel within the same area. When it is detected as a change in the reception area, the channel selection list accumulated conventionally is cleared, and a favorite channel is set based on newly acquired data. When the channel is partially moved, the channel change information is acquired and the contents of the channel selection list obtained in the past are used. An object of the present invention is to realize a receiving apparatus that can easily select a favorite channel.

  The present invention comprises the following means in order to solve the above problems.

That is,
The reception time of the broadcast received by selecting the channel is accumulated for each reception channel, the order of the reception channels is determined in the order of the accumulated reception time, and the designated broadcast is received according to this determination. In this case, the broadcast reception method in which the channel reception is changed in the same broadcast area and the broadcast reception in which the channel is changed when moving to a broadcast area different from the same area is performed based on the order. There,
When the channel change is detected (151), a first step (15) for determining a ratio of the number of received channels changed to the number of receivable channels;
A second step (16) for clearing the accumulated reception time for each reception channel on the assumption that the mobile station has moved to the different broadcast area when the ratio obtained in the first step exceeds a predetermined value;
A broadcast receiving method comprising the steps of: (15) determining a reception channel order of a broadcast received after the second step, and receiving a broadcast designated in accordance with the determination.

  According to the broadcast receiving method of the present invention, the following effects can be provided.

That is,
When the reception area is changed and many reception channels of the received broadcast are changed to different reception channels, the accumulated reception time for each reception channel is cleared, so the change is made without performing complicated operations. Thus, it is possible to realize a broadcast receiving apparatus having suitable operability that designates a receiving channel order in the received area and selects a desired receiving channel.

  The preferred embodiments of the broadcast receiving method according to the present invention will be described below.

  FIG. 1 shows a schematic configuration of a broadcast receiving apparatus according to the first embodiment, which will be described with reference to the drawings.

  The broadcast receiving apparatus 1 shown in FIG. 1 includes a tuner 11, a TS (Transport Stream) decoder 12, an AV (Audio visual) decoder 13, a video multiplexing unit 14, a system controller 15, a memory 16, and a display control unit 18. . An antenna is connected to the tuner 11. A monitor 3 is connected to the video multiplexing unit 14. An operation input unit is connected to the system controller 15. The system controller 15 includes an initialization detection unit 151.

  First, the operation input unit is operated, or a channel selection button of a remote controller (not shown) is operated, and a broadcast channel to be received is set in the system controller 15. The set reception channel information is input to the tuner 11.

  The tuner 11 switches either the signal input from the UHF / VHF antenna or the first intermediate frequency signal supplied from the satellite dish receiving parabola antenna based on the signal related to the input reception channel. And receive the broadcast wave of the specified channel.

  Here, when the received signal is a digital satellite broadcast, a digital CS broadcast, or a digital terrestrial broadcast, the signal obtained from the tuner 11 is a bit stream by a transport stream (TS). The TS signal is supplied to the TS decoder 12 where it is decoded.

  The TS signal is packetized and compression-encoded digital audio signal, compression-encoded digital video signal, and packetized data related to additional information of programs and channels. The digital audio and digital video signals are supplied to the AV decoder 13, where signals encoded by, for example, MPEG (moving picture experts group) -2 are decoded, and audio signals and video signals are obtained. These signals are supplied to the monitor 3 via the video multiplexing unit 14, where they are sounded and displayed. When the received signal is analog broadcasting, the video signal demodulated by the tuner 11 is input to the video multiplexing unit 14.

  The packetized data relating to the additional information obtained from the TS decoder 12 is supplied to the system controller 15. The system controller 15 acquires information related to the broadcast being received from the supplied data, and the acquired information is created as a list of broadcast channels that the user likes based on the viewing time of the viewer and is stored in the memory 16. . The stored information is aggregated and used as viewing history table creation information described later.

  The viewing history table created by the system controller 15 can be displayed on the monitor 3 by the user operating the operation input unit or the remote controller. That is, the viewing history table is generated as a display bitmap signal by the display control unit 18 and is displayed by the video multiplexing unit 14 so as to be superposed on the video signal being received.

  The viewing history table is displayed on the monitor 3 when the user starts reception by the broadcast receiving apparatus 1. In the displayed viewing history table, the system controller 15 designates a broadcast channel having the longest viewing time or a broadcast channel desired to be viewed, so that the system controller 15 performs digital satellite broadcasting, digital CS broadcasting, digital terrestrial broadcasting, analog terrestrial broadcasting, etc. The selection related to the reception method, the selection of the channel broadcasted by the reception method, and the designation of the subchannel when a plurality of subchannels are broadcast on the broadcast channel are simultaneously performed.

  Next, when the broadcast receiving apparatus 1 is moved due to moving or the like, the initialization detection unit 151 built in the system controller 15 detects that the broadcast area has been changed to a different area. The detection is performed based on whether a part of the terrestrial broadcast channels has been changed or a number of broadcast channels have been changed.

  When it is detected that some of the broadcast channels have been changed, information related to the changed channel is obtained, and the reception channel of the viewing history table is converted based on the obtained information. For example, when the broadcast channel is changed by analog-analog conversion related to the introduction of digital terrestrial broadcasting, the reception channel of the history table accumulated based on viewing is updated as the history table for the changed channel.

  Based on the updated viewing history table, the program reception function using the stored viewing history table information is maintained.

  On the other hand, when a large number of broadcast channels are changed, the direction transmitting / receiving apparatus 1 is moved to a region different from the conventional one. In these cases, the contents of the viewing history table are initialized. The initialization is performed when the broadcast receiving apparatus is moved and the broadcast area is changed by detecting the receiving channel setting operation.

  Further, when the owner (user) of the broadcast receiving apparatus is changed, information relating to the owner stored in the apparatus is initialized. When the owner is changed, channel selection is performed in accordance with the preference for the new owner. The preference system controller 15 detects the execution of the initialization function, and initializes the contents of the viewing history table when detected.

  As described above, the creation of the viewing history information table, the reception of the broadcast performed using the viewing history information table, and the updating and initialization of the viewing history information table in the broadcast receiving apparatus 1 have been described.

  Next, the viewing history information table will be further described.

  FIG. 2 shows a description example of the viewing history information table, which will be described with reference to the drawings.

  In the figure, a cumulative viewing time for each reception channel is described by a table of 24 sheets for every hour obtained by dividing a day into 24 equal parts. The best 10 at time T1 shows the 10 reception channels in descending order of the cumulative total viewing time for each reception channel in the midnight range.

  As the viewing history information, a channel number, channel additional information, and total viewing time are described. When the received channel is a channel belonging to the best 10, the system controller 15 updates the viewing time every time the channel is received. When the updated viewing time exceeds the viewing time of a program with a higher rank, the rank is switched. When a program not in the top 10 is viewed and the viewing time of the 10th place is exceeded, the 10th place channel is replaced with a new channel.

  Similarly, a cumulative viewing time for each viewing channel in another time zone is created. The created viewing history information table is displayed as ranking information at that time by operation. The user designates the order of the displayed channel with the 10 keys of the remote controller to start receiving the channel.

  Since the viewing history information table is a table created based on the channel information received based on the user's preference, for example, when the user of the broadcast receiving apparatus is changed, the data related to the past cumulative viewing time is unnecessary. Become.

  For example, when information related to the user's name, date of birth, etc. is rewritten, the data related to past cumulative viewing time is deleted, and a new viewing history information table is created based on the viewing history of a new user. To do. In addition, when the location is changed to a different broadcast service area due to relocation and the installation location of the broadcast receiving device is changed, the data related to the past cumulative viewing time is deleted. This is because, when different broadcaster series are received on the same broadcast channel, the meaning of the accumulated viewing time data for each channel accumulated at the installation location before the movement is lost.

  On the other hand, with the start of terrestrial digital broadcasting, some analog broadcasting channels are changed in order to prevent interference between digital broadcasting channels and analog broadcasting channels. A simple reception channel selection function for designating the channel order can be utilized as it is without deleting the history information table information.

  FIG. 3 is a flowchart showing operations related to creation and deletion of the viewing history information table.

  First, when the operation information of the operation input unit of the broadcast receiving apparatus 1 is supplied to the system controller 15 and the reception channel of the tuner 11 is selected, the reception channel selected in S (step) 61 corresponds to the current time. To check whether it exists in the viewing history information table. When it exists, the viewing time (Vt) of the viewing history information table is input to a viewing time counter (not shown) of the system controller 15. When it does not exist, 0 is input to the viewing time counter.

  The viewing time counter adds (increments) the viewing time until the reception channel is set to a new channel, for example, every minute. In step S62, it is detected whether a channel selection operation has been performed. When no operation is detected, the operations after S67 are performed, and S62 is executed after a series of operations.

  When the channel selection operation is detected, if the viewing time of the receiving channel for which 0 is entered as the viewing time exceeds the 10th total viewing time, the data in the 10th channel number column is changed to the data related to the new receiving channel. Rewrite. When the received channel is the channel within the 10th place, the viewing time of the channel number is rewritten to the viewing time counter time.

  In S63, it is detected whether or not the order has been changed in the viewing history information table based on the update result. If the order has been changed, the order of the registered channels is changed in S64. After the end of S64 and when the order of registered channels is not changed in S63, reception of the reception channel selected in S62 is started in S65.

  In S66, the time information of the viewing time counter is set for the newly received channel by the same method as described above, and the set time information is incremented for each viewing time. The viewing of the new program is continued until the next new channel is selected while repeating the operations after S67. When the next new channel selection is detected in S62, the viewing history information table is updated in the same manner as described above.

  Next, the operation after S67 will be described.

  In S67, it is detected whether or not a history clear key operation for clearing the viewing time stored in the viewing history information table has been performed. The history clear key operation is detected as a viewing history clear operation when a plurality of predetermined keys are operated simultaneously or when a menu screen is displayed and the predetermined keys are operated in a predetermined order.

  When it is detected that the above key operation has been performed and the viewing history clear operation has been performed, all data of the channel number, channel information, and viewing time in the viewing history information table are cleared in S72. All data of history information stored in association with channel operation is initialized.

  If an operation for clearing the viewing history is not detected in S67, it is detected in S68 whether a preset key operation for the reception channel has been performed. Receiving channel presetting is an operation performed when the broadcast receiving area is changed at the time of purchase of the broadcast receiving apparatus or moving.

  When the preset operation of the reception channel is performed, the postal code or the telephone number is input in S69 to set the channel, and then all the viewing history data is cleared in S72.

  If a channel preset key operation is not detected in S68, it is detected in S70 whether the user information clear key operation has been performed. When an operation is detected, personal information such as the owner's name and address is cleared in S71, and then all viewing history data is cleared in S72.

  After all viewing history data has been cleared in S72, and when a clear key operation for user information is not detected in S70, it is detected in S73 whether a display request operation for channel viewing order information based on the viewing history information table has been performed. If detected, a list is displayed in S74. After the display, the operations after S62 are repeated. When a channel selection operation is performed based on the display, the channel selection key operation is detected in S62, and the above operation is repeated.

  In the above-described operation, the viewing history information table is updated so as to aggregate the accumulated time information of the channels viewed every time. Accordingly, for example, when the time is changed from 19:59 to 20:00 during broadcast reception, the viewing history information table at 19 o'clock is updated on the assumption that the viewing has ended at 19:59:59.

  After that, it is assumed that the same reception channel is selected from 20:00:00, and reception is started. Loading of new Vt data to the viewing time counter based on time information in the 20 o'clock range and viewing every minute Increment time.

  In the above-described example, an example has been described in which 24 viewing history information tables are created every hour, and a favorite channel is easily accessed and viewed based on channel information for each viewing time. Arrangement of preference channels by time is not limited to every hour, but for example, a preference channel may be found by ranking every 4 hours.

  In addition, since the organization of broadcast programs is often repeated on a weekly basis, a viewing history information table relating to a preference channel for one week may be created every four hours. In that case, the program can be viewed in such a way as to prevent the program being viewed every week from being inadvertently missed.

  When there is no change in the broadcast area and the users are the same, the same reception channel is often viewed repeatedly on a weekly basis. Therefore, for example, when a part of broadcast channels is changed by analog-analog conversion, a broadcast channel with a higher rank is not received, and a new broadcast is received.

  When one broadcast channel is changed, the stored viewing time information can be continuously used by changing both the channel numbers of the viewing history information table. When a plurality of broadcast channels are changed, it is necessary to know the correspondence between the channels before and after the change.

  Since the viewing history information tables tabulated every week show the same viewing tendency, a channel correspondence table for each broadcaster can be created by comparing the viewing time rates before and after the channel change. Based on the correspondence table, the channel number of the viewing history information table can be corrected, and a broadcast receiving apparatus capable of suitably selecting a favorite channel based on the received data accumulated in the past can be configured.

  As described above, in a broadcast receiving apparatus that creates a viewing history information table at every predetermined time interval and easily selects and views a favorite broadcast channel based on the created table, a reception channel preset operation or a user information clear operation If the broadcast reception area is changed or the user of the device is changed, the history of the viewing history information table is cleared when It is possible to select and receive a favorite channel, and when a part of the broadcast channel is changed, by using a viewing history information table accumulated by changing the channel number of the viewing history information table, a simple operation can be performed. The configuration and operation of a broadcast receiving apparatus capable of selecting a receiving channel have been described.

  In the case of a digital broadcast receiver, since the broadcaster of the receiving channel can be identified using program information received as additional information, it is easy to change the channel number described in the viewing history information table when the receiving channel is changed. I can do it.

  In the case of terrestrial digital broadcasting, information related to the change of the broadcast channel is transmitted as notification information for frequency repacking. A terrestrial digital broadcast receiving apparatus monitors section data called SDTT (Software Download Trigger Table) when the power is turned on, for example.

  When the repacking notice information is received, the channel number of the viewing history information table may be replaced based on that information, or the information stored in the viewing history information table may be cleared.

  However, in the case of terrestrial analog broadcasting, for example, when broadcaster information or program information is added to the vertical synchronization section and received, reception channel change information can be obtained based on that information, but such service is provided. Not. Therefore, the reception channel change information is obtained based on the viewing history information table.

  The channel selection using the viewing history information table is performed by selecting a medium to be received such as terrestrial analog broadcast, analog satellite broadcast, digital satellite broadcast, digital communication satellite broadcast reception, and terrestrial digital broadcast. Multiple switching such as selection and sub-channel selection can be performed with one touch by specifying rank information, so channel selection suitable for broadcast receiving devices that select and receive many broadcast media It is possible to configure a broadcast receiving apparatus that performs reception.

  The present invention can be used to realize a broadcast receiving apparatus that uses a plurality of broadcast media and can select a program received through a large number of channels by a simple operation based on user preference information.

It is a figure which shows schematic structure of the broadcast receiving apparatus based on the Example of this invention. It is a figure which shows the example of a description of the viewing history information table based on the Example of this invention. 6 is a flowchart illustrating operations for creating and deleting a viewing history information table according to an embodiment of the present invention.
