Description

  The present invention relates to a technique for avoiding inconvenience associated with the fact that reservation information such as a preset recording reservation cannot be received.

  In a communication device such as a portable information device with a built-in TV tuner and GPS, a television program or the like is usually recorded at home using this information device and viewed at a destination.

  However, there is a problem in that when the information device is taken out to the destination while the recording reservation is in place, if the destination is an area where the reserved recording program cannot be viewed, recording fails. In other words, the user is relieved that the recording will be executed once the reservation information such as the recording reservation is properly set, but will be discouraged when actually trying to play back the recording later was there.

  Here, there is a technique in which viewing is continued by changing the channel preset to another area having good reception sensitivity based on the current position information. For example, program viewing is continued by changing from NHK Tokyo to NHK Shizuoka.

The broadcast program recording system includes an instruction device mounted on a vehicle and a fixed device fixedly installed at a user's home, and the control circuit of the instruction device uses a channel set in the in-vehicle television. Detects and generates channel information. When the operation of the operation switch or the vehicle speed is detected to exceed a certain threshold, the control circuit transmits the channel information via the wireless communication device, and is transmitted. The channel information is converted into a channel suitable for the recording device by the recording control device, the recording control device causes the recording device to record, and the recording device receives the radio wave having a good S / N from the antenna and records it. A technique has been proposed in which a broadcast program received by a mobile object can be recorded only by a simple operation, and the image quality and sound quality of the recorded content can be improved (for example, Patent Document 1). Irradiation).

  However, in the related technology described above, for example, in the case of a broadcasting station that can be received only in some areas such as Tokyo MX TV and TV Kanagawa, the problem of being unable to watch and failing to record cannot be solved.

  Also, even if the reception sensitivity is low due to tunnels, underpasses, valleys of buildings, weather conditions, etc., it cannot be viewed and the problem of failing to record cannot be solved.

  Since it is supposed to be recorded at home where it can be received, there is a possibility of going to an area where reception is not possible when going out, so if you leave the entrance of the house, you can automatically make a reservation transfer to your home PC Certainly, if the reservation data is completely transferred and disappears from the portable information device, the recording cannot be played back and enjoyed on the portable information device while out. In addition, if the reservation is automatically transferred to the home PC, useless transmission / reception of data occurs when frequent entry / exit is repeated, resulting in various costs.

  The present invention has been made to solve the above-described problems, and prevents the situation where recording information such as a recording reservation once set cannot receive a program or the like, thereby preventing a situation in which recording is missed and recording reliably. An object is to provide a communication device, a reservation transfer system, and a program to be secured.

  When there is a recording reservation that starts within a predetermined time, the first communication device of the present invention refers to a database that maps whether or not the recording CH broadcast can be received for each area, and broadcasts the recording CH during the recording time zone. It is determined whether or not the recording can be received, and when the reception is not possible, the recording reservation data is transferred to another device capable of recording.

  Further, the second communication device of the present invention is characterized in that it is judged whether or not the broadcast of the recording CH can be received at the present time, and when the broadcast cannot be received, the recording reservation data is transferred to another device capable of recording.

  In the first reservation transfer system of the present invention, when there is a recording reservation that starts within a predetermined time, the communication apparatus refers to a database that maps the availability of reception of the recording CH for each area with reference to the recording time. It is determined whether or not the broadcast of the recording CH can be received in the band, and when the reception is not possible, the recording reservation data is transferred to another device capable of recording.

  In the second reservation transfer system of the present invention, the communication device determines whether or not the broadcast of the recording channel can be received at the present time, and if not, transfers the recording reservation data to another recordable device. It is characterized by.

  Further, the first program of the present invention, when there is a recording reservation to be started within a predetermined time in the computer, records in the recording time zone with reference to the database mapping whether or not the recording CH broadcast can be received for each area. It is determined whether or not the CH broadcast can be received, and if it cannot be received, a process of transferring the recording reservation data to another device capable of recording is executed.

  In addition, the second program of the present invention makes the computer determine whether or not the broadcast of the recording CH can be received at the present time, and if not, can execute a process of transferring the recording reservation data to another recordable device. It is characterized by that.

  According to the present invention, since reservation information such as a recording reservation that has been set once cannot receive a program or the like, it is possible to prevent a situation in which recording is missed and to ensure recording.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The reservation transfer system in the present embodiment shown in FIG. 1 is configured by connecting a portable device 100 and a home PC 200 via the Internet 1000.

  The mobile device 100 is an information processing device such as a mobile phone, and may be any communication device.

  Home PC 200 is an information processing apparatus such as a personal computer having a recording function installed at home or the like and a recording reservation function thereof.

  The Internet 1000 is an example of a network and may be an arbitrary line regardless of wired or wireless.

  The mobile device 100 includes an antenna 101, a video receiving unit 102, a video display unit 103, a reception sensitivity determination unit 104, a reservation management unit 105, a reservation setting unit 106, a reception area map database 107, and a reservation list database 108. A data transmission unit 109, a route management unit 110, a route search unit 111, and a GPS 112.

  The video receiving unit 102 receives the video using the antenna 101 and causes the video display unit 103 to display the received video.

  The reception sensitivity determination unit 104 determines the sensitivity with which the video reception unit 102 receives video using the antenna 101. If the reception sensitivity is poor, it is not possible to obtain a clean normal video.

  The reservation management unit 105 manages recording reservations such as programs from the reservation setting unit 106 using the reservation list database 108. Here, the reservation is made for, for example, a TV program, but is not limited to this, and includes all data such as text broadcast, text such as CM, still image, moving image, and voice. In addition, the reservation management unit 105 refers to the reception area map database 107 to determine whether or not a reserved program can be recorded. Except when it is determined that recording is possible, the reservation management unit 105 receives data from the data transmission unit 109 via the Internet 1000. The recording reservation data is transferred to the home PC 200.

  The route management unit 110 grasps the current position and route of the own device from the route searched by the route search unit 111 and the current position information from the GPS 112. The route search unit 111 may be realized in cooperation with, for example, a car navigation system.

  The home PC 200 includes an antenna 201, a video reception unit 202, a video display unit 203, a reservation management unit 204, and a data reception unit 205.

  The video receiving unit 202 receives the video using the antenna 201 and causes the video display unit 203 to display the received video. The reservation management unit 204 receives and manages the recording reservation data transferred from the data transmission unit 109 of the portable device 100 via the Internet 1000 by the data reception unit 205. Reservation information is extracted from CSV data using e-mail or the like, and is managed and executed using an HDD recording function or the like.

  This system confirms the current position by GPS when a certain time before the scheduled recording time, and the mobile device 100 is in an area where the scheduled recording program cannot be received, or by setting a destination such as a car navigation system, Has a function of automatically transmitting recording reservation information to the home PC 200 and acting as a substitute when there is a possibility of going out of the receivable area. Note that the scheduled location at the recording start time or the recording time may be predicted based on the result data of the train transfer search, the data of the schedule management book, the position data of the ETC system, or the like.

  FIG. 2 is a diagram for explaining the update of the reception area map stored in the reception area map database 107. Here, for example, a receivable area map as shown in FIG. 3 is constructed.

  In the initial state, a map in which broadcast areas are divided by prefectural borders and municipalities is used. For example, “Tokyo” is in the 23 wards, “Tama” is in the Fuchu city or the national city, and so on.

This map is updated with the actual reception sensitivity.
The mobile device 100 periodically transmits the reception sensitivity to the server 300 managing the service map by the data transmission / reception unit 114.

  At the time of transmission, the latitude / longitude information acquired from the GPS 112, time, weather information, etc. are added and transmitted. The weather information is determined by the rain determination unit 113 by, for example, determining the presence / absence of rain based on information from a system that monitors the operation status of the linked windshield wipers.

  In areas where reception sensitivity differs depending on time and weather, service maps are prepared for each time zone and weather based on past accumulated information and updated based on received data.

The map is subdivided at regular intervals, and if it cannot be received despite the receivable area, the subdivided area is changed to unreceivable. On the contrary, when it is possible to receive the signal even though it was an unreceivable area, the area may be changed to a receivable area. By receiving data from many users, a more accurate service map is constructed.

  The reservation management unit 105 of the mobile device 100 refers to the reception area map database 107 and determines whether or not a reserved program can be received by checking the corresponding broadcast area map based on the time and the weather of the recording reservation time zone. Then, it is determined whether or not recording is possible, and unless it is determined that recording is possible, recording reservation data is transferred from the data transmission unit 109 to the home PC 200. This broadcast area map may be downloaded each time and stored in the mobile device 100, or may be confirmed on the spot by connecting to a predetermined server.

Hereinafter, the operation of the present embodiment will be described in detail with reference to the drawings.
First, the reception sensitivity information generation flow with position information will be described with reference to FIG.

  The reception sensitivity determination unit 104 of the portable device 100 determines the sensitivity with which the video reception unit 102 receives video using the antenna 101 (S401). If the reception sensitivity is poor, it is not possible to obtain a clean normal video.

  At the same time, the reception sensitivity determination unit 104 of the portable device 100 acquires time information at that time from a predetermined timer (S402).

  In addition, the reception sensitivity determination unit 104 of the portable device 100 acquires the current location information of the own device using the GPS 112 (S403).

  In addition, the reception sensitivity determination unit 104 of the portable device 100 acquires the operation status of the wiper using the rain determination unit 113 (S404). As a result, it is determined that it is raining when the wiper is operating for a certain period of time, and is not raining otherwise.

  The reception sensitivity determination unit 104 of the mobile device 100 transmits these data to the reception area map DB 107 (S405), the reception area map DB 107 stores these data in association with each other, and updates the map data.

  Note that the processing performed by the reception sensitivity determination unit 104 of the mobile device 100 may be performed by any part as long as it is realized by a control unit such as a CPU, and the data in the reception area map DB 107 is managed anywhere including the outside. May be.

Next, the recording reservation transfer process flow will be described with reference to FIG.
The reservation management unit 105 of the mobile device 100 manages recording reservations for programs and the like from the reservation setting unit 106 using the reservation list database 108. First, the reservation management unit 105 of the mobile device 100 determines whether there is a recording reservation that starts within a predetermined X minutes with reference to the reservation list database 108 (S501). Note that X minutes is, for example, 30 minutes, and is determined by comparing and balancing the time sufficient for the transfer processing of the recording reservation data and the possibility of further movement.

  Next, when there is a recording reservation (S501 / Yes), the reservation management unit 105 of the mobile device 100 checks the recording reservation program (S502). As a result, it is determined whether or not the scheduled recording program is an area-limited broadcast.

  Then, the route management unit 110 of the mobile device 100 confirms the route information searched by the route search unit 111, and determines whether route guidance is being performed (S503, S504).

  When route guidance is being performed (S504 / Yes), the reservation management unit 105 of the mobile device 100 refers to the reception area map database 107 to determine whether or not the broadcast of the recording CH can be received during the recording time period (S505). .

  When the broadcast of the recording CH cannot be received in the recording time zone (S505 / No), the reservation management unit 105 of the portable device 100 transfers the recording reservation data from the data transmission unit 109 to the home PC 200 via the Internet 1000 (S506). . As a result, even when the mobile device 100 is in an area where the broadcast of the recording CH cannot be received during the recording time zone, the recording reservation is made at the home PC 200, so that the situation where the recording was actually made but the recording could not be performed is avoided. Can do. The data recorded on the home PC 200 may be transferred to the mobile device 100 of the user who is out.

  When the broadcast of the recording CH can be received during the recording time zone (S505 / Yes), the recording is performed on the mobile device 100 as it is (S507).

  On the other hand, when route guidance is not being performed (S504 / No), the route management unit 110 of the mobile device 100 confirms the current location that is the current position of the mobile device and the movement locus within a certain period of time based on the current location information from the GPS 112. At the same time, the distance from the boundary of the reception area is confirmed with reference to the reception area map database 107 (S508).

  Then, the reservation management unit 105 of the mobile device 100 determines whether or not the reception sensitivity determination unit 104 can receive the broadcast of the recorded CH at the present time (S509).

  If the broadcast of the recording channel cannot be received or received at the present time, but the reception sensitivity is extremely poor, or it is close to the boundary of the reception area, it goes out of the area from the previous movement track and fails to record. If the possibility is high (S509 / No), the reservation management unit 105 of the portable device 100 transfers the recording reservation data from the data transmission unit 109 to the home PC 200 via the Internet 1000 (S506). As described above, even if the mobile device 100 is in an area where the broadcast of the recording CH cannot be received during the recording time zone, the recording reservation is made at the home PC 200, so that the recording was actually made but the recording could not be performed. Can be avoided. Similarly, data recorded by the home PC 200 may be transferred to the mobile device 100 of the user who is out.

  When the broadcast of the recording CH can be received at the present time (S509 / Yes), the recording is performed on the mobile device 100 as it is (S507).

  According to the present embodiment, unlike related technology that can only make a reservation setting from the outside to the home PC, it is possible to prevent missed shooting according to the reception sensitivity or by predicting the reception sensitivity.

  Each of the above-described embodiments is a preferred embodiment of the present invention, and various modifications can be made without departing from the scope of the present invention. For example, you may perform the process which implement | achieves the function of each apparatus by making each apparatus read and run the program for implement | achieving the function of the portable apparatus 100 and the home PC200.
