Description

The present invention, servers apparatus for outputting a broadcast program receives broadcast waves from a broadcast station, the broadcast program output system, a broadcast program output terminal and the broadcast program output program.

  Digital terrestrial television broadcasting has started, and high-definition image content suitable for viewing on a large-screen, high-definition television receiver (hereinafter simply referred to as “TV”) has been enhanced. In broadcast broadcasting and the like, it is possible to watch a program full of realism. In addition, with the widespread use of recording media that can record a large amount of high-definition images with the same image quality, such as hard disk recorders, it is possible to view such content at a time convenient for the viewer.

On the other hand, with the widespread use of portable televisions, in particular with the increase in mobile phones equipped with television functions, it is possible to obtain various types of information from information-providing programs such as news on the go. While this becomes convenient, it also increases the possibility that the user will accidentally obtain information that he / she does not intend to obtain. Obtained do not want information and is, for example, sports that are relayed broadcast program that had been reserved for recording match results, and the like.

  The content viewing system described in Patent Document 1 as a method for reducing the risk of acquiring information that is not desired is intended to prevent acquisition of information that the user does not want to obtain. When a recording reservation is made for a program that is sequentially transmitted according to the electronic program guide, viewing output on the display device is limited for the program and a program related to the program.

On the other hand, the network 300 and the base station Data communication is possible with various servers such as a content distribution server and a stationary recording apparatus 500 such as a hard disk recorder.

  FIG. 2 is a block diagram showing a configuration of the mobile phone device 100 according to the first embodiment of the present invention.

  The mobile phone device 100 includes a broadcast receiving unit 112 including a TV antenna 110 and a TV tuner 111, a communication unit 113, a display unit 114, an operation unit 115, a storage unit 116, a GPS unit 118, a speaker 119, and a microphone 120. Central processing unit) 117 is connected. Each of these components is housed in a housing 121. The casing 121 is made of a synthetic resin such as plastic.

  The television antenna 110 receives a broadcast wave transmitted from the transmission facility of the broadcast station 200, for example, a television broadcast wave. The TV tuner 111 is connected to the TV antenna 110 and extracts a specific frequency band signal from the TV broadcast wave received by the TV antenna 110, thereby enabling selection of a broadcast channel. For example, when a user selects a channel on which a broadcast program is desired, a broadcast signal in a frequency band corresponding to the selected channel is extracted and sent to the display unit 114, the storage unit 116, and the like. The broadcast receiving unit 112 corresponds to a broadcast receiving unit.

  The communication unit 113 that is a terminal-side communication means is configured to include an antenna for telephone communication and data communication, and is built in the housing 121, and includes various networks 300 such as a mobile communication network, a public telephone communication network, and the Internet.

When the mobile phone device 100 moves, the base station 400 and the communication unit 113 are always connected to the destination base station 400 by radio connection every time the mobile phone device 100 moves. It is possible to do.

  The communication unit 113 is connected to a content distribution server or the like via the network 300, and can download moving image data, audio data, and the like to the mobile phone device 100 by data communication.

  The display unit 114 is an output unit that displays a received television broadcast program video, downloaded video data video, a menu screen for selecting operations during telephone communication and data communication, a setting screen, and the like. The display unit 114 is not particularly limited. For example, a liquid crystal display realized by a liquid crystal display element such as a transmission type, a semi-transmission type, or a reflection type, or an EL realized by an EL (Electro Luminescence) element or the like. A display etc. are mentioned.

  The operation unit 115 is a selection means for operating the mobile phone device 100. For example, an input key for inputting numbers and characters, a function key for setting or selecting various functions of the mobile phone device 100, a power source A keyboard including a power key for switching between ON and OFF states is included. When the user performs a key operation on the keyboard, the operation unit 115 sends a key operation detection signal corresponding to the key operation to the CPU 117.

  The operation unit 115 may be separated from the mobile phone device main body and can be remotely controlled, or may be a combination of the display unit 114 and a touch panel.

  The CPU 117 identifies the key operation detection signal, and executes predetermined processing according to the identification result, for example, retrieval of a telephone number in the telephone directory file, storage of the telephone number and image data in the storage unit 116, and the like. .

  The storage unit 116 is composed of, for example, a RAM (Random Access Memory) and a flash ROM (Read Only Memory), and the like, a program for the CPU 117 to control the operation of each part constituting the mobile phone 100, and a control command from the CPU 117. , Various data including video data and audio data indicating broadcast contents based on broadcast waves received via the communication antenna of the television antenna 110 and the communication unit 113, and the caller such as the other party's telephone number and the other party's name It is a storage means for storing telephone book data associated with identification information and the like.

  The speaker 119 converts an audio signal received during telephone communication and outputs it as audio. The microphone 120 generates an audio signal from the audio input during telephone communication, and inputs the generated audio signal to the CPU 117.

  The acquisition unit, the creation unit, the comparison unit, and the movement detection unit include a CPU 117 and a storage unit 116 that are control units.

  Hereinafter, the operation of the mobile phone device 100 during normal use will be described. The cellular phone device 100 can perform telephone communication, data communication, and television reception.

  First, telephone communication will be described. When an instruction to start telephone communication is given by a key operation of the operation unit 115 by the user at the time of outgoing call or reception, the CPU 117 causes the communication unit 113 to connect to the network 200 via the communication antenna, Have wireless communication. At the time of reception, the CPU 117 performs radio processing and baseband processing on radio waves in a predetermined frequency band received by the communication antenna, generates a reception signal, and sends it to the speaker 119. The speaker 119 converts the received reception signal into sound and outputs it. At the time of transmission, the user's voice is input to the microphone 120. The microphone 120 converts the input voice to generate a transmission signal, and inputs the generated transmission signal to the CPU 117. Then, CPU 117 performs baseband processing, radio processing, etc. on the transmission signal given from microphone 120 and transmits radio waves in a predetermined frequency band from the communication antenna to the base station. The above operation is continued until an instruction to end telephone communication is given by the user through a key operation on the operation unit 115.

  Next, data communication will be described. For example, when a user gives an instruction to start data communication by operating the key of the operation unit 115 during transmission / reception of an e-mail, the CPU 117 causes the communication unit 113 to connect to the network 300 via a communication antenna to perform wireless data communication. To do. The communication unit 113 transmits the text data created by the user by operating the keys of the operation unit 115, or receives various data including moving image data and audio data indicating broadcast contents based on the broadcast wave to the network 300. Data communication is performed with other portable terminal devices and servers through the network.

  The reception of the television broadcast will be described. When an instruction to start reception of a television broadcast is given by a user operating the operation unit 115, the CPU 117 receives a television broadcast wave transmitted from a broadcasting station via the television antenna 110. Then, the TV tuner 111 selects a channel of a target broadcasting station such as the Japan Broadcasting Corporation (NHK) according to the user's selection from a plurality of television broadcasting waves received by the TV antenna 110, and selects the channel. Image data, audio data, and the like indicating broadcast contents based on the broadcast television broadcast wave are sent to the display unit 114 and the speaker 119. The display unit 114 displays videos of various data such as received moving image data. At this time, the audio data is output from the speaker 119. This operation is continued until an instruction to end the television reception is given by the key operation of the operation unit 415 from the user.

  In addition, when the user wants to view the recorded content recorded in the broadcast receiving device such as the hard disk recorder 300, the notification signal instructing the transmission of the recorded data including the moving image data and the audio data indicating the broadcast content is provided. The data can be transmitted to the broadcast receiving device by data communication. The recorded data can be received from the broadcast receiving apparatus through the data communication. The received recording data can be viewed by causing the display unit 414 and the receiving unit 419 to simultaneously output audio and video based on the recording data.

  In the mobile phone device 100, in order not to output information that the user does not want to obtain, it is possible to restrict the output of moving images and audio based on broadcast programs.

  In order to make the output restriction effective, it is first necessary to set an output restriction condition. For the condition setting, for example, the setting function of the mobile phone 100 is used, and the output restriction information is stored in the storage unit 116. The output restriction information may be input by the user operating the operation unit 115. When a recording reservation is made by a recording device at home, the reservation content is received from the recording device by data communication and received. You may make it create from the reserved contents.

  Here, the output restriction information includes, for example, “broadcast program title”, “broadcast program genre”, and the like. It is also possible to directly input “broadcast station name and program broadcast time” as a condition.

  The mobile phone device 100 is configured to be able to acquire EPG (electronic program guide) data. The procedure for acquiring the EPG data itself is possible with existing technology. There are a procedure for acquiring from the EPG server via a network and a procedure for extracting and acquiring EPG data superimposed on a television broadcast wave. The cellular phone device 100 can acquire EPG data in any procedure by the TV tuner 111, the communication unit 113, and the CPU 117.

  Based on the input output restriction information and the EPG data, a broadcast program subject to output restriction is specified, and a list of broadcast programs is created and stored in the storage unit 116 as restriction target program information.

FIG. 3 is a diagram illustrating an example of the EPG data 10.
For example, consider a case where the EPG data obtained in a certain broadcast area (assumed as area A) on a certain day is as shown in FIG. In this example, the broadcast station name 11 is described in the top row, and the broadcast time (24-hour notation) 12 is described in the leftmost column, where the broadcast station name and the broadcast time intersect. A broadcast program name 13 is described.

  When a broadcast program name “World Baseball Final” is set as output restriction information, EPG data is searched using a character string indicating the broadcast program name as a search key. As a result of the search, only a program called “19:00” start and “22:00” end, that is, a program called the World Baseball Final, is broadcast by the Japanese public broadcast (A district general) of channel “1” in “A” area. Are extracted and listed as restriction target program information.

  When the program genre of “baseball related” is set as the output restriction information, “22” is broadcasted every morning in the A area of the channel “3” in the “A” region, in addition to the “world baseball final game”. : 54 ”start,“ 24:09 ”end broadcast program, that is, the news report 23 program,“ A ”region channel“ 8 ”TV“ A ”area,“ 23:00 ”start,“ 23:45 ”end A broadcast program, that is, a program called sports news is extracted and listed as restriction target program information. FIG. 4 is a diagram illustrating a data structure of the restriction target program information 20. The restriction target program information 20 includes, for example, a region name 21, a channel 22, a start time 23, and an end time 24 as program specific information for restricting output.

  Broadcast programs such as BS (Broadcasting Satellite) satellite and CS (Communication Satellite) satellite broadcast have the same program content in any region of Japan, but terrestrial analog broadcast and digital terrestrial broadcast programs are In many cases, the program content varies depending on the prefecture. Therefore, the contents of the EPG data are also different for each district. Because of its portability, mobile phone device 100 often moves across different regions where broadcast stations that can be received. If the broadcasting station has moved to a different area, the program that should originally be restricted cannot be restricted with the original settings, or the output of programs that do not need to be restricted may be restricted. Will end up. Therefore, in the present invention, when the EPG data is changed, the newly acquired EPG data is compared with the output restriction information again, and the restriction target program information is updated.

  When the user starts an operation in order to watch a TV program, the user refers to the restriction target program information 20 and determines whether the current time is between the start time 23 and the end time 24 of the entire list. If not, program video and audio are output, and if they are in between, the channels associated with the corresponding start time 23 and end time 24 are referred to. If the channel (broadcast station) selected by the user does not match the channel referenced, the program video and audio are output, and if they match, the output is restricted. Any mode may be used to limit the output as long as the user cannot view video and audio. For example, if the corresponding channel cannot be selected, even if it can be selected, the screen is displayed in black with no sound, or the output is restricted such as “Do you want to output baseball-related information? If there is no need to restrict at the time of confirmation, the restriction may be released.

  Furthermore, when the mobile phone device 100 has a recording function, until the output restriction is canceled, the reproduction of the recorded program video and audio is restricted even if the restriction target program can be recorded. You can also.

  The output restriction can be released by switching the output restriction information from valid to invalid, or deleting the output restriction information using the setting function of the mobile phone device 100.

FIG. 5 is a flowchart showing the output restriction process of the mobile phone device 100.
First, in step S1, the conditions of a program for which output restriction is desired are stored in the storage unit 116 as output restriction information.

  In step S2, the current broadcast area is recognized using a broadcast signal of a television broadcast wave or position information of the base station 400 with which the communication unit 113 is communicating, and the broadcast wave received from the antenna 110 in step S3. Alternatively, an electronic program guide (EPG data) for the current broadcast area is obtained by packet communication using a mobile communication network. If the input output restriction information is the recording reservation content set by the external recording apparatus 500, EPG data may be received from the recording apparatus 500.

  Next, in step S4, based on the output restriction information and the EPG data, a broadcast program subject to output restriction is specified, and a list of target broadcast programs is created as restriction target program information. In step S5, it is determined whether or not the output restriction has been released. If it has been released, the process ends. If not, the process proceeds to step S6. In step S6, it is determined whether or not the output of the program whose output is to be restricted has been selected. If it has been selected, the process proceeds to step S7, where output is blocked. If not selected, the process proceeds to step S8.

  In step S8, it is determined whether or not the contents of the broadcast program and the receivable broadcasting station have changed. If changed, the process proceeds to step S9, and if not changed, the process returns to step S5.

  In step S9, the current broadcast area is re-recognized, and in step S10, EPG data for the current broadcast area is newly obtained. If the currently stored EPG data is different from the new EPG data, in step S11, based on the output restriction information and the new EPG data, the broadcast program subject to the output restriction is specified again. Update restriction target program information.

  The reason why the restriction target program information is updated is that the broadcast time is extended in, for example, a baseball broadcast program, and the broadcast program is changed due to an external factor, and the mobile phone device 100 is moved, etc. Both cases can be considered. For this reason, the trigger for starting the acquisition of EPG data includes a passive trigger such as receiving EPG data when it is superimposed on a broadcast wave, and receiving EPG data when it is sent from outside by data communication, and periodically. Check the update by accessing the EPG server, receive EPG data when the broadcast area where the device exists changes due to movement, etc., or check if the EPG data has been updated if there is a user instruction It is desirable to have both of the active and the like.

  When creating a new restricted program list, when confirming to the user “Are you sure you want to set this?”, It is desirable to output and confirm only the changes.

  As a result, even if the content of the broadcast program or the receivable broadcast station changes, it is possible to always perform appropriate output restriction. In particular, even when a broadcast station with completely different broadcast contents can be received because the number of broadcast stations that can be received increases because the number of broadcast stations that can be received increases.

  In particular, when the mobile phone device 100 moves from one broadcast area to another, the user cannot receive broadcast programs in the previous area, so there is a high possibility of zapping. Risk increases. For this reason, the apparatus itself detects the movement and updates the list of broadcast programs whose output is to be restricted. Alternatively, it is desirable to add a broadcast program whose output is to be restricted in the destination broadcast area to the list.

  Therefore, it is desirable that the mobile phone device 100 includes a means for detecting the current broadcast area. For example, a map in which a broadcast area is registered is prepared, and the current broadcast area is detected by comparing the current position calculated based on the latitude and longitude output from the GPS unit 118 with the map. Receivable broadcasts equipped with a tuner that is different from the tuner used to display broadcast programs that receives information on base stations when connecting to a mobile communication network and detects broadcast areas corresponding to the base station areas. For example, a station is always searched for and a broadcast area is detected based on a receivable broadcast station. If the broadcast area changes, it is possible to reduce the possibility that the program whose output should be restricted cannot be restricted by obtaining new EPG data as soon as possible.

  Further, when the mobile phone device 100 has a navigation function such as a car navigation function or a pedestrian navigation function, EPG data effective in the new broadcast area is obtained when the mobile phone device 100 actually moves to the new broadcast area. Instead, the broadcast area passing through the current location and the route determined from the destination set by the user is regarded as the current broadcast area, EPG data for those broadcast areas is acquired in advance, and those broadcasts are obtained. It is also possible to create restriction target program information in advance for the area. In this case, since different broadcast stations are assigned to the same channel in different broadcast areas, it is desirable to perform the restriction after confirming the current position when performing output restriction.

  The broadcast area from which EPG data is acquired is preferably all the broadcast areas that pass through, but some EPG data is acquired in advance in consideration of the storage capacity of the mobile phone device and the communication speed at which data communication is possible. It may be. Since the route is determined, EPG data of the broadcast area that will pass next may be acquired in advance according to the order of passage.

  As a result, it is possible to reduce the possibility that the broadcast program that should be output restricted cannot be restricted due to the delay in obtaining the EPG data, and it is possible to further restrict the output more appropriately.

Hereinafter, a second embodiment of the present invention will be described.
In the first embodiment, the mobile phone device obtains the EPG data, and creates and updates the list of broadcast programs subject to output restriction. In this embodiment, the restriction target program is stored in an external server. This is a configuration for creating information. This method is particularly effective when the computing capability and storage capacity of the mobile phone device 100 are small.

  Since the configuration of the mobile phone device 100 is the same as that of the first embodiment, detailed description thereof is omitted. In this embodiment, the case where the above-described recording device 500 operates as a server device will be described as an example. However, the server device is not limited to a hard disk recorder such as the recording device 500, but an optical disk recorder, a video deck, a home server, You may implement | achieve with a personal computer etc.

FIG. 6 is a block diagram illustrating a configuration of the recording device 500.
The recording apparatus 500 includes a tuner 512 connected to an antenna 511, a communication unit 513, a large capacity storage unit 514, an operation unit 515, and a storage unit 516 connected to a CPU 517.

  The antenna 511 is disposed toward the broadcast station 200 and receives a broadcast wave transmitted from the broadcast station 200, for example, a television broadcast wave. The tuner 512 is connected to the antenna 511 and performs the same operation as the TV tuner 111 of the mobile phone device 100.

  The communication unit 513 is an interface for connecting to the network 300, and performs data communication by wireless communication with the mobile phone device 100 via the base station 400 connected to the network 300. Further, the communication unit 513 can acquire EPG data from an EGP server on the network 300.

  The large-capacity storage unit 514 includes an encoder and a decoder, and the video data and audio data transmitted from the tuner 512 are compressed by the encoder into a predetermined file format, such as MPEG (Moving Picture Experts Group phase) format. The compressed data is stored in a connected hard disk drive (hereinafter referred to as HDD). The HDD records compressed data in file units. The recorded compressed data is decoded and decompressed into original moving image data and audio data by a decoder.

  The operation unit 515 is an operation unit for operating the recording apparatus 500, and includes keys such as function keys for setting or selecting various functions. Examples of the function keys include a recording key for starting recording processing, a reproduction key for starting reproduction processing of recorded recording data, and a stop key for stopping recording processing or reproduction processing. When the user performs a key operation, the operation unit 515 inputs a key operation detection signal corresponding to the key operation to the CPU 517. The CPU 517 identifies the input key operation detection signal, and executes a predetermined process according to the identification result, such as a recording process or a reproduction process.

  The storage unit 516 includes, for example, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. A program for the CPU 517 to control the operation of each part constituting the recording device 500, a control command from the CPU 517, and the like. Remember. The CPU 517 is mainly composed of a microcomputer, and controls the operation of each part constituting the recording apparatus 500, executes a program read from the storage unit 516, and the like.

First, the operation during the normal operation of the recording apparatus 500 will be described.
In a normal operation, when a recording process start instruction is given by a user through a key operation on the operation unit 515, the CPU 517 instructs the tuner 512 to select a broadcasting station according to the user's selection, and is transmitted from the tuner 512. Video data, audio data, and the like are transferred to the mass storage unit 514. The large-capacity storage unit 514 encodes and compresses the moving image data, audio data, and the like sent from the tuner 512 into compressed data in a predetermined file format, for example, MPEG format, and stores the compressed data.

  The above-described recording process is continued until a recording process stop instruction is issued by the user through a key operation on the operation unit 515, or until a predetermined recording time and recording end time have elapsed by the reserved recording function.

  With the reserved recording function, the communication unit 513 acquires EPG data via the network 518 when an instruction for reserved recording is given by a key operation of the operation unit 515 from the user. Then, the user can make a recording reservation for the target program based on the acquired EPG data. The recording instruction and the reservation recording instruction can also be performed from the cellular phone device 100.

  When the output restriction information is input, the current position of the mobile phone device 100 is changed, the broadcast area is changed, or when an update instruction is input from the user, the mobile phone device 100 newly sets the restriction target program information. Therefore, the program information to be restricted is transmitted to the recording apparatus 500 that creates and updates the information based on the output restriction information and the area information indicating the current broadcast area.

  The recording apparatus 500 accesses the EPG server and acquires EPG data based on the received area information by data communication.

Next, the recording apparatus 500 identifies broadcast programs that are subject to output restriction based on the received output restriction information and EPG data, and creates a list of target broadcast programs as restriction target program information. The creation of the list is the same as in the first embodiment, and a description thereof will be omitted. The recording apparatus 500 transmits the created list of programs that are subject to viewing restriction to the portable television receiver 1.

  When receiving the restriction target program information created or updated by the recording device 500, the cellular phone device 100 overwrites and updates the restriction target program information already stored.

  The means for restricting the output based on the restriction target program information is the same as in the first embodiment.

  The server that creates a list of programs that are subject to viewing restriction may be a public service server. In this case, instead of obtaining an electronic program guide according to the list of received broadcast stations, an electronic program guide corresponding to all broadcast stations targeted for service in advance (for example, if Japan is the target of service, Electronic program guides corresponding to all TV stations in Japan may be acquired and held by themselves.

  In the first and second embodiments described above, the mobile phone device 100 is described as receiving television broadcasts, but this is only an example. The mobile phone device 100 may have a radio reception function for receiving an audio broadcast. Further, it may be a so-called Internet broadcast receiver that receives program content data from a content distribution server using data communication. In this case, the broadcast area is a region based on the current position of the device whose output is to be restricted. (For example, a region that can be specified by measuring latitude and longitude with GPS), but not a region on the network, for example, to which network or domain the ISP (Internet Services Provider) or access point belongs May be used. Further, it may be a composite terminal apparatus having these various reception functions.
