(Embodiment 1)
An embodiment of the present invention will be described below with reference to FIGS.
In the present embodiment, an example is shown in which a terminal that is currently viewing a program (migration source terminal) specifies a program that is to be viewed on a terminal that is newly viewing the program (migration destination terminal).

  FIG. 1 is a block diagram showing a schematic configuration of a viewing system according to the present embodiment, which is composed of a mobile phone 1 and a television 2. It is assumed that the mobile phone 1 can receive a terrestrial digital broadcast mobile reception service and the television 2 can receive a fixed reception service.

FIG. 2 is a block diagram of the mobile phone 1. The antenna 11 receives digital broadcast waves. The broadcast receiving unit 12 extracts data information such as video / audio of a designated channel and program information from the radio wave received by the antenna 11. The video / audio processing unit 13 decodes the video and audio stream output from the broadcast receiving unit 12. The display / output unit 14 outputs the video data / audio data decoded by the video / audio processing unit 13 as video and audio. The control unit 15 creates a command to be transmitted to the television 2 and gives an instruction to the remote control communication unit 16. The remote control communication unit 16 emits a remote control signal that can control the television 2 based on an instruction from the control unit 15.
Before describing the detailed processing, the handling of channel numbers used for selecting a viewing station in digital terrestrial broadcasting will be briefly described.

There are roughly three types of channel selection methods using the remote control of the terrestrial digital broadcast receiver. There are three types: “one channel selection” by one-touch buttons (1 to 12), “up / down channel selection” by channel up / down buttons, and “direct channel selection” by inputting a three-digit channel number.
Here, “direct channel selection” is to directly designate the three-digit channel number of a specific broadcasting station using the number buttons (0 to 9), as in BS digital broadcasting. This three-digit channel number is calculated from the following equation.
3-digit channel number = (service type × 200) + (remote control key ID × 10) + (service number + 1)

  Here, a television service (fixed reception service) (0), a data service (1 and 2), and a partial reception service (mobile reception service) (3) are assigned as service types. For example, in the Tokyo area, the remote control key ID is assigned such that NHK General is 1 and Nippon Television is 4. As for the service number, the broadcasting station assigns 0 to 7 to the service of its own station.

  Although the mobile phone itself in this embodiment is not selected by the remote controller, it has information corresponding to the above-mentioned three-digit channel for the program that the local station is watching.

FIG. 3 is a flowchart of processing of the mobile phone 1 that is performed when the user views the program that the user was watching on the mobile phone 1 on the television 2.
Here, the user views the mobile reception service using the mobile phone 1. At this time, the broadcast wave received by the antenna 11 is separated into video, audio, and data by the broadcast receiving unit 12. The user views the video and audio output via the video / audio processing unit 13 and the display / output unit 14.
The user turns on the power of the television 2 in order to view the program of the fixed reception service having the same content as the program of the mobile reception service that was viewed on the mobile phone 1 on the television 2.

Hereinafter, processing in the mobile phone 1 will be described.
First, when the user presses a predetermined switch (not shown) provided on the mobile phone 1, the control unit 15 detects it (S1).
The control unit 15 obtains the 3-digit channel number of the currently received program from the broadcast receiving unit 12. Then, the number of the tenth place is acquired as a common remote control key ID even in the fixed reception service received by the television 2. Here, assuming that the three-digit channel number of the program of the mobile reception service currently being received is 641, the remote control key ID is 4.

  Next, the control unit 15 generates a three-digit channel number for fixed reception service (S2). In the above example, if the service type is TV service, 0, the remote control key ID is 4 as described above, and the service number is fixed to 0, the 3-digit channel number for the fixed reception service is (0 × 200) + ( 4 × 10) + (0 + 1) = 041.

Subsequently, the control unit 15 generates a command for changing the reception channel of the television 2 to the three-digit channel number specified above, and transmits the command to the television 2 via the remote control communication unit 16 (S3).
When the television 2 receives the remote control signal, it changes the channel of the fixed reception service received at its own station in the same manner as when operating with a normal remote control. Since this process is the same as the operation when receiving a remote control signal in a normal television, the description is omitted.

(Embodiment 2)
One embodiment of the present invention will be described below with reference to FIGS.
In the present embodiment, when a program to be viewed at a terminal (transfer destination terminal) for newly viewing a program is specified at a terminal currently viewing a program (transfer source terminal), An example of selection is shown. Note that a description of the same contents as those in Embodiment 1 is omitted.
The schematic configuration of the viewing system according to the present embodiment is the same as that of the first embodiment.

FIG. 4 is a block diagram of the mobile phone 1. Here, the names and numbers of the respective blocks are the same as those in FIG. 2, and the description of the same blocks is omitted.
The broadcast data processing unit 17 analyzes and extracts program information related to the currently viewed program included in the broadcast data. The network communication unit 18 acquires EPG information that can be received by the television 2 from the network 3 such as the Internet. These program information and EPG information include a program name, broadcast date and time, program content, G code, and the like.

FIG. 5 is a flowchart of processing of the mobile phone 1 that is performed when the user views the program that the user was watching on the mobile phone 1 on the television 2.
In the same situation as in the first embodiment, when the user presses a predetermined switch (not shown) provided on the mobile phone 1, the control unit 15 detects it (S11) and starts the following processing. .

  The control unit 15 specifies the currently viewed program from the current time obtained from the broadcast data processing unit 17 and the currently viewed channel information, and acquires the program name (S12). Subsequently, EPG information related to the broadcast that can be received by the television 2 is acquired from the network communication unit 18. In this embodiment, it is electronic program guide information related to the fixed reception service. The EPG information is searched using the program name acquired in S12 as a key, and a program having the same program name is detected (S13). Here, the process is distributed according to how many programs are detected (S14).

If no program is detected, the control unit 15 displays the fact on the display / output unit 14 (S15), and returns to the switch pressing detection waiting state.
When only one is detected, the channel number of the program is specified from the EPG information obtained previously (S17). If a plurality of items are found, the control unit 15 displays them on the display / output unit 14 and makes a selection by the user (S16), and identifies the channel number of the program based on the result (S17). .

Subsequently, the control unit 15 generates a command for instructing the television 2 to change to the specified channel number, and transmits the command to the television 2 via the remote control communication unit 16 (S18).
When the television 2 receives the remote control signal, it changes the channel of the fixed reception service received at its own station in the same manner as when operating with a normal remote control. Since this process is the same as the operation when receiving a remote control signal in a normal television, the description is omitted.

(Embodiment 3)
The following describes one embodiment of the present invention with reference to FIGS.
In the present embodiment, the attributes of the viewing program are extracted at the terminal currently viewing the program (migration source terminal), the attribute information is transmitted to the terminal (migration destination terminal) for newly viewing the program, and the migration destination An example in which a program to be viewed on a terminal is specified will be shown.

FIG. 6 is a block diagram of the television 2. The antenna 31, the video / audio processing unit 33, the display / output unit 34, and the broadcast data processing unit 37 have the same functions as the blocks having the same names in FIG.
The broadcast receiving unit 32 can receive a fixed reception service. The control unit 35 instructs the broadcast receiving unit 32 to change the received program based on an instruction input from the remote control communication unit 36 described later. The remote control communication unit 36 transmits the input remote control signal to the control unit 35.

FIG. 7 is a flowchart of processing of the mobile phone 1 that is performed when the user views the program that the user was watching on the mobile phone 1 on the television 2.
The steps of detecting the switch press in S21 and detecting the program name from the program information being received in S22 are the same as S11 and S12 in FIG.
After S22, the control unit 35 transmits the obtained program name as a viewing program change command to the television 2 via the remote control communication unit 36 (S23).

FIG. 8 is a flowchart of processing of the television 2 after detection of the remote control signal.
When the remote control communication unit 36 detects a remote control signal (S31), it transmits a command included in the signal to the control unit 35. The control unit 35 determines the content of the received command, and if it is a viewing program change command, extracts the program name from it. Subsequently, the control unit 35 acquires EPG information related to the broadcast that can be received by the own terminal from the broadcast data processing unit 37. In this embodiment, it is electronic program guide information related to the fixed reception service. The EPG information is searched using the program name transmitted from the mobile phone 1 as a key, and a program having the same program name is detected (S32). Here, the process is distributed according to how many programs are detected (S33).

If no program is detected, the control unit 35 displays that fact on the display / output unit 34 (S34), and returns to the switch press detection waiting state.
When only one is detected, the channel number of the program is specified from the EPG information obtained previously (S36). If a plurality of items are found, the control unit 35 displays the plurality of items on the display / output unit 34, allows the user to make a selection (S35), and specifies the channel number of the program based on the result (S36). .

  Subsequently, the control unit 35 changes the channel number of the program received by the broadcast receiving unit 32 using the specified channel number (S37). As a result, a program having the same program name as the program of the mobile reception service received by the mobile phone 1 can also be received by the fixed reception service of the television 2.

(Embodiment 4)
The following describes one embodiment of the present invention with reference to FIGS.
In the present embodiment, an example is shown in which a broadcast related to a broadcast that has been viewed on a television is continuously viewed on a mobile phone.
Since the viewing system in the present embodiment is shown in FIG. 1 as in the first embodiment, description thereof is omitted.

  FIG. 9 is a block diagram of the mobile phone 1 in the present embodiment. This is basically the same as FIG. The difference is that the control unit 15 issues an instruction to the broadcast receiving unit 12 and the remote control communication unit 16 is a bidirectional remote control and can transmit a received signal to the control unit 15.

  FIG. 10 is a block diagram of the television 2 in the present embodiment. This is basically the same as FIG. The difference is that the broadcast data processing unit 37 does not exist, and the remote control communication unit 36 is a bidirectional remote control, and can transmit a command from the control unit 35 to the outside.

  FIG. 11 is a flowchart of processing of the mobile phone 1 in the present embodiment. When the user presses a predetermined switch (not shown) provided on the mobile phone 1, the control unit 15 detects it (S41) and starts the following processing.

  The control unit 15 activates the television function (S42) and creates a channel information request for the television 2. Here, the control unit 15 stores that the mobile phone 1 can receive the mobile reception service, and adds to the channel information request that the mobile reception service can be received. And it transmits to the television 2 via the remote control communication part 16 (S43), and waits for a response (S44).

  When receiving a response from the television 2 that has performed processing described later in FIG. 12 (S45), the remote control processing unit 16 transmits the response to the control unit 15. The control unit 15 takes out the channel information included in the response and sets the channel in the broadcast receiving unit 12 (S46). The broadcast receiving unit 12 changes the viewing channel to this channel, and outputs video and audio via the video / audio processing unit 13 and the display / output unit 14. As a result, it is possible to receive a mobile reception service program transmitted from the same broadcasting station as the fixed reception service program viewed on the television 2.

FIG. 12 is a flowchart of processing of the television 2 when detecting a remote control signal.
When receiving the remote control signal (S51), the remote control communication unit 36 transmits a command included in the signal to the control unit 35. The control unit 35 determines the content of the received command. If the command is a channel information request, the 3-digit channel information of the program currently being viewed is received from the broadcast receiving unit 32, and the 3-digit channel number for mobile reception service is calculated (S52). This calculation is performed by substituting service type = 3 (partial reception service), remote control key ID = 4, and service number = 0 in the formula described in Embodiment 1 (the program being viewed on the television 2). 3 digit channel number is 041). Then, a channel information response including the channel number is created and transmitted to the mobile phone 1 via the remote control communication unit 36 (S53).

In the above embodiment, the combination of the mobile phone 1 and the TV 2 has been described. However, the transfer source terminal and the transfer destination terminal are not limited to this combination, and viewing may be transferred from the TV to the mobile phone. Other types of terminals such as a PC may be used.
