  FIG. 6 is a diagram illustrating a first example of signal transmission / reception between the mobile terminal 6 and the STB 4. FIG. 6 shows an example in which the STB 4 is compatible with the push-type communication protocol (WebSocket is used in this embodiment). The process is started when the program 15 is activated in the STB 4 and the program 25 is activated in the portable terminal 6.

  First, the portable terminal 6 transmits a request signal S1 for establishing a connection for HTTP (HyperText Transfer Protocol) communication from the communication unit 22 to the STB 4 by the transmission processing unit 44.

  The STB 4 receives the request signal S 1 via the communication unit 13 by the reception processing unit 33. The STB 4 that has received the request signal S 1 transmits the response signal S 2 from the communication unit 13 to the mobile terminal 6 by the transmission processing unit 34. The portable terminal 6 receives the response signal S <b> 2 via the communication unit 22 by the reception processing unit 43. Thereby, the connection of HTTP communication is established between the portable terminal 6 and the STB 4.

  The STB 4 holds a document described in a predetermined markup language such as HTML (HyperText Markup Language) in the screen processing unit 35. The STB 4 is configured to display basic operation screens (up / down / left / right keys, a determination button, a return button, and other basic operation buttons for use as a remote control) by the transmission processing unit 34 after the connection of the HTTP communication is established. Screen) HTML document is transmitted from the communication unit 13 to the portable terminal 6. The portable terminal 6 receives the HTML document via the communication unit 22 by the reception processing unit 43. The portable terminal 6 that has received the HTML document displays the HTML document of the basic operation screen received by the reception processing unit 43 on the display unit 24 by the display processing unit 41 having an HTML browser function. Note that the HTML document of the basic operation screen may not be transmitted from the STB 4 to the mobile terminal 6 but may be held in advance by the mobile terminal 6.

  Next, the mobile phone 6 transmits a request signal S3 for establishing a WebSocket connection from the communication unit 22 to the STB 4 by the transmission processing unit 44.

  The STB 4 receives the request signal S 3 via the communication unit 13 by the reception processing unit 33. The STB 4 that has received the request signal S <b> 3 transmits the response signal S <b> 4 from the communication unit 13 to the portable terminal 6 by the transmission processing unit 34. The portable terminal 6 receives the response signal S4 via the communication unit 22 by the reception processing unit 43. As a result, a WebSocket connection is established between the mobile terminal 6 and the STB 4. In the WebSocket, once a connection is established, the connection is maintained even if no signal is transmitted / received between the mobile terminal 6 and the STB 4 unless a request signal for terminating the connection is transmitted.

  After the WebSocket connection is established, the STB 4 uses the detection processing unit 32 to monitor the occurrence of an event (event) that should change the operation screen of the remote controller.

  For example, it is assumed that content for which viewing age restriction is not set is broadcast during a certain time period, and another content for which viewing age restriction is set is broadcast during the next time period. Further, it is assumed that the television 5 connected to the STB 4 is set to be unable to view the content for which the viewing age limit is set by default. The STB 4 receives the video signal of the content transmitted from the server 2 by the communication unit 12 (video receiving unit). Then, the video processing unit 31 performs processing such as decoding on the received video signal, and monitors whether or not the viewing age limit is set (or details of the limit) for each content. In the present embodiment, in order to view content for which viewing age restriction is set on the television 5, a password input is required, and a password input screen for the user to enter a password is displayed on the display unit of the mobile terminal 6. 24. Therefore, the STB 4 detects, as an occurrence of an event, that the detection processing unit 32 has started reception of content for which viewing age restriction has been set and it is necessary to display a password input screen on the remote controller.

  Further, for example, a case is assumed where a certain program is reserved for viewing or recording by a user. Setting information for viewing reservation or recording reservation is held by the STB 4. In the present embodiment, a predetermined start notification message for notifying the user of the start of the content is sent to the mobile terminal 6 at the start of the content reserved for viewing or recording or immediately before (for example, several minutes before). It is displayed on the display unit 24. Therefore, the STB 4 detects the occurrence of an event by the detection processing unit 32 that the content reserved for viewing or recording is started or the start time is approaching.

  When the detection processing unit 32 detects the occurrence of an event, the STB 4 transmits screen update information S5 for updating the operation screen of the remote controller from the communication unit 13 to the portable terminal 6 by the transmission processing unit 34. The screen update information S5 may be an HTML document of the entire operation screen including a password input screen or a start notification message, or a password input screen or a start notification in part of the basic operation screen using JSON (JavaScript Object Notation). It is also possible to add a message.

  Further, in this embodiment, when the STB 4 detects the occurrence of an event, the STB 4 transmits the screen update information S5 to the mobile terminal 6 by WebSocket push-type communication. The portable terminal 6 receives the screen update information S5 via the communication unit 22 by the reception processing unit 43. The mobile terminal 6 that has received the screen update information S5 causes the update processing unit 42 to change the basic operation screen displayed on the display unit 24 into an operation screen including a password input screen and a start notification message based on the screen update information S5. Update. The transmission of the screen update information S5 from the STB 4 to the mobile terminal 6 may be performed by HTTP pull type communication. For example, when the STB 4 detects the occurrence of an event, the mobile terminal 6 transmits a message to that effect to the mobile terminal 6, and the mobile terminal 6 that has received the message transmits a request signal for the screen update information S 5 to the STB 4. The received STB 4 transmits the screen update information S5 to the portable terminal 6.

  FIG. 7 is a diagram illustrating a second example of signal transmission / reception between the mobile terminal 6 and the STB 4. FIG. 7 shows an example in which the STB 4 does not support WebSocket. Hereinafter, the difference from the first example shown in FIG. 6 will be mainly described.

  First, the portable terminal 6 transmits the request signal S1 to the STB 4 by the transmission processing unit 44.

  The STB 4 receives the request signal S1 by the reception processing unit 33. The STB 4 that has received the request signal S <b> 1 transmits the response signal S <b> 2 toward the portable terminal 6 by the transmission processing unit 34. The portable terminal 6 receives the response signal S2 by the reception processing unit 43. Thereby, the connection of HTTP communication is established between the portable terminal 6 and the STB 4.

  The STB 4 transmits the HTML document of the basic operation screen to the mobile terminal 6 by the transmission processing unit 44 after the connection of the HTTP communication is established. The portable terminal 6 receives the HTML document by the reception processing unit 43. The mobile terminal 6 that has received the HTML document causes the display processing unit 41 to display a basic operation screen on the display unit 24.

  Next, the portable terminal 6 transmits a request signal S3 for establishing a WebSocket connection to the STB 4 by the transmission processing unit 44.

  The STB 4 receives the request signal S3 via the communication unit 13 by the reception processing unit 33. The STB 4 that has received the request signal S3 does not transmit the response signal S4 illustrated in FIG. 6 to the mobile terminal 6 because it does not support WebSocket. The portable terminal 6 determines that the STB 4 is not compatible with WebSocket by not receiving the response signal S4 from the STB 4 within a predetermined time after transmitting the request signal S3.

  In this case, the portable terminal 6 transmits request signals S71, S72, S73, S74,... For requesting the screen update information S5 from the communication unit 22 to the STB 4 by the request processing unit 45. The request signals S71, S72, S73, S74,... Are transmitted from the mobile terminal 6 at regular intervals (for example, several minutes to several tens of minutes) by HTTP communication.

  STB4 receives request signals S71, S72, S73, S74,... Via the communication unit 13 by the reception processing unit 33. As described above, the STB 4 monitors the occurrence of an event by the detection processing unit 32. If the occurrence of an event is not detected when a certain request signal is received, the STB 4 does not transmit the screen update information S5 for the request signal, and the detection processing unit 32 detects the occurrence of the event. In response to the first request signal received later, the transmission processing unit 34 transmits the screen update information S5 to the mobile terminal 6. In the example shown in FIG. 7, the occurrence of an event is detected after receiving the request signal S72, and the screen update information S5 is transmitted in response to the next request signal S73.

  When the reception processing unit 43 receives the screen update information S <b> 5, the portable terminal 6 updates the remote controller operation screen using the update processing unit 42.

  Thus, according to the video reception system (or STB 4, mobile terminal 6, programs 15, 25, control method of STB 4, control method of mobile terminal 6) according to the present embodiment, in STB 4, the transmission processing unit 34 When the detection processing unit 32 detects the occurrence of a predetermined event, screen update information S5 for updating the operation screen displayed on the display unit 24 of the mobile terminal 6 with the occurrence of the event is stored in the mobile terminal. Send to 6 In the mobile terminal 6, the reception processing unit 43 receives the screen update information S <b> 5 transmitted from the STB 4, and the update processing unit 42 receives the operation screen displayed on the display unit 24. The screen update information S5 is updated. Therefore, when a predetermined event occurs in the STB 4, the operation screen displayed on the display unit 24 of the mobile terminal 6 can be updated according to the event. In addition, a WebSocket connection is established between the mobile terminal 6 and the STB 4. Therefore, when an event occurs in the STB 4, the STB 4 can transmit the screen update information S 5 to the mobile terminal 6 by WebSocket push-type communication.

  Also, according to the video reception system according to the present embodiment, the reception processing unit 43 receives the screen update information S5 transmitted from the STB 4 by using WebSocket push type communication. In the pull communication protocol, the STB 4 receives the request from the mobile terminal 6 and transmits the screen update information S5. Therefore, the screen update information S5 is not transmitted until the request is received after the event occurs. Therefore, a time lag occurs between the event occurrence timing and the screen update information S5 transmission timing (see FIG. 7). On the other hand, in push-type communication, the STB 4 voluntarily transmits the screen update information S5 without waiting for a request from the mobile terminal 6 when an event occurs. Accordingly, there is no time lag between the event occurrence timing and the screen update information S5 transmission timing. According to the video reception system according to the present embodiment, STB 4 transmits screen update information S5 by push-type communication, and reception processing unit 43 of mobile terminal 6 receives this. Accordingly, the STB 4 can transmit the screen update information S5 to the mobile terminal 6 without delay, and as a result, the mobile terminal 6 can update the operation screen displayed on the display unit 24 without delay. Become. Moreover, in the pull communication protocol, it is necessary to periodically request the screen update information S5 from the mobile terminal 6 to the STB 4 regardless of whether an event has occurred. In the push communication protocol, such a periodic communication is required. Since no request is required, communication traffic between the mobile terminal 6 and the STB 4 can be reduced.

  Further, according to the video reception system according to the present embodiment, the request processing unit 45 performs the request signals S71, S72, S73, and S74 when the connection of the WebSocket is not established between the mobile terminal 6 and the STB 4. ,... Periodically request screen update information S5 from STB4. As a result, even if the STB 4 does not support WebSocket, the mobile terminal 6 periodically requests the screen update information S5 from the STB 4 through the HTTP pull-type communication. The screen update information S5 can be received.

  Further, according to the video receiving system according to the present embodiment, the screen update information S5 includes operation screen information such as a password input screen for releasing the viewing age restriction. Therefore, when the STB 4 receives the content for which the viewing age limit is set, the screen update information S5 including the operation screen information is transmitted from the STB 4 to the mobile terminal 6 so that the password is input to the display unit 24 of the mobile terminal 6 A screen or the like can be displayed.

  Further, according to the video receiving system according to the present embodiment, the screen update information S5 includes a start notification message for notifying the start of a program reserved for viewing or recording. Accordingly, at or just before the start of the program reserved for viewing or recording, the screen update information S5 including the start notification message of the program is transmitted from the STB 4 to the portable terminal 6 to the display unit 24 of the portable terminal 6. The start notification message can be displayed.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined not by the above-mentioned meaning but by the scope of claims for patent, and is intended to include all modifications within the scope and meaning equivalent to the scope of claims for patent.
