To be supplied. Thereby, the menu screen and the program guide screen are displayed on the display 134.

  A menu image signal for display, a program guide image signal, and the like can be transmitted to the portable terminal 700. When the portable terminal 700 requests a menu image signal, a program guide image signal, etc., the display processing unit 212 can transmit the menu image signal and the program guide image signal to the portable terminal 700.

  The portable terminal 700 can display the menu image signal and the program guide image signal on the screen of the touch panel, and the user touches the operation button displayed on the screen of the touch (or point) panel, thereby An operation command signal can be given to the John device 100.

  For example, the portable terminal 700 can send the specified information of the content to be taken out to the television apparatus 100. Then, the content management unit 215 of the television receiving device 100 converts the content of the corresponding program in accordance with the performance (capacity, resolution, etc.) of the portable terminal 700 when the designation information of the content to be taken out is sent. And means for storing and preparing in a preparation unit in the content management unit 251.

  Then, the content management unit 215 includes means for detecting a state in which the portable terminal 700 enters a communication area of a predetermined area (that is, a communication area of the wireless communication transmission / reception unit 113) in combination with the communication control unit 203. And when it detects that the portable terminal 700 exists in the said communication range, the means to transmit the said taking-out content to the portable terminal 700 are provided.

  In addition, the content management unit 215 can transmit the taken-out content to the other second portable terminal of the portable terminal 700. Of course, in this case, the second mobile terminal designates the content to be taken out and makes a reservation for taking out the content. A plurality of portable terminals are registered in the device management unit 204.

  FIG. 2 is a simplified diagram showing an example of a situation where the content management unit 251 performs an operation specific to this system.

  Now, it is assumed that the television receiver 100 is set in the home HOM. In this case, the recording device is not limited to the television receiving device 100, and may be a recording device adopting the present embodiment.

  Also, now, the portable terminal 700A transmits the specified content specification information to the content management unit 215 of the television receiver 100, and the content C1 of the corresponding program is prepared and transmitted to the preparation unit of the content management unit 215. It is assumed that preparation is completed in a possible state.

Thereafter, it is assumed that the portable terminal 700A has entered the communication area WA of the wireless communication transmitting / receiving unit 113 (for example, the communication area using Wi-Fi (registered trademark)).
Then, this is detected by the content management unit 215, and the carry-out content that has been reserved for take-out is automatically downloaded to the portable terminal 700A via the Wi-Fi terminal (also referred to as an access point). .

  In addition, it is assumed that the portable terminal 700B has reserved other content to be taken out. However, when the portable terminal 700B is outside the communication area WA of the wireless communication transmitting / receiving unit 113 (for example, the communication area based on Wi-Fi (registered trademark)), automatic download of the content to be carried out to the portable terminal 700B is not executed.

  FIG. 3 is an explanatory diagram showing the timing of the above-described operation. Assume that the mobile terminal A is within the communication range and the mobile terminal B is outside the communication range. Under the control of the communication control unit 203, a call is made to the electronic device in the communication area via the access point W (t1). When portable terminal 700A responds to this call, mutual authentication is performed between communication control unit 203 and portable terminal 700A (t3).

  As a result of the mutual authentication, when there is a taken-out content reserved by the portable terminal 700A, downloading of the taken-out content is executed with the operation of the content management unit 251 (t4, t5). Then, the portable terminal 700A stores the sent-out content that has been sent in the memory (t6).

  On the other hand, when the portable terminal 700B that exists outside the communication area moves into the communication area, communication is started between the communication control unit 203 and the portable terminal 700B (t11, t12), and mutual authentication is performed. (T13). As a result of mutual authentication, when there is a take-out content reserved by the portable terminal 700B, download of the take-out content is executed with the operation of the content management unit 251 (t14, t15). Then, the portable terminal 700A stores the sent-out content that has been sent in the memory (t16).

  As described above, the present embodiment performs content transmission / reception control of a device that receives and / or records content. That is, the designation of the first carry-out content is accepted from the first portable terminal, and the first carry-out content for the first portable terminal is prepared. In addition, it is possible to detect whether any of the plurality of portable terminals has entered the communication area of the predetermined area. When the first mobile terminal is detected to be in the communication range and the preparation is completed, the first carry-out content is automatically transmitted to the first mobile terminal.

  FIG. 4 shows an operation example in the case where, for example, the portable terminal A1 makes a reservation for content to be taken out toward the television device 100.

  The content management unit 251 detects that a take-out reservation for the content C1 has been entered from the mobile terminal A1 (SA1). For this take-out reservation, for example, a program list of a broadcast program or a program list of a recorded program is sent to the portable terminal A1, and the user looks at this program list and designates the program name by touch operation etc. Reservations can be made.

  When a take-out reservation for the content C1 is entered from the portable terminal A1, the content management unit 251 determines whether the content C1 is the content C1 sent in a future broadcast program (SA2). In the case of a future broadcast program, the content management unit 251 makes a reception reservation for a program including the content C1. Precisely, the channel reservation for the program is reserved. The portable terminal A1 can also make a recording reservation at the same time as a take-out reservation. When the portable terminal A1 makes a recording reservation together with a take-out reservation for a program including the content C1, the content management unit 251 also makes a recording reservation for the program. Similarly, viewing reservations can be made.

  Thereafter, the content management unit 251 notifies that the portable terminal A1 has made a take-out reservation or a recording reservation (SA4).

  In contrast to the above processing, when it is determined in SA2 and SA5 that the program of the content C1 is already recorded in the recording / playback apparatus 111, the following processing is executed. That is, the program is reproduced and the content C1 is converted for takeout, and the takeout content C1 is prepared in the takeout memory, and the preparation is completed.

  The content C1 for taking out is converted and prepared so as to conform to the display method, display resolution, memory capacity, etc. of the portable terminal A1. Then, it is determined whether or not the mobile terminal A1 is within the communication range described above (SA8). If it is within the communication range, the take-out content C1 is downloaded to the mobile terminal A1 (SA9). When the mobile terminal A1 is not detected within the communication range described above, the mobile terminal A1 enters a standby state for detecting that the mobile terminal A1 enters the communication range (SA10).

  In the previous SA5, when the program of the content C1 is not recorded on the recording / reproducing apparatus 111 and the program of the content C1 has already been broadcast, the following processing is executed. That is, the mobile station A1 is notified that the program of the content C1 has already been broadcast and has not been recorded. However, when there is a rebroadcast as judged from the EPG, it is possible to notify the portable terminal A1 that the content C1 by the rebroadcast program has been taken out and reserved and to notify the date of preparation. .

  FIG. 5 is a diagram showing still another example of functions in the content management unit. For example, when the take-out reservation is made for the content of the program D and the content of the program D is taken out, the take-out number is managed in the take-out number management unit 251b.

  Then, the number of contents taken out of the program D is input to the dubbing count counter 251a of the program D. The dubbing count section 251a manages the number of dubbing of the program D, and manages to reduce the remaining number of dubbing by one when there is one take-out according to the rule of dubbing 10.

  When the take-out reservation is made exceeding the predetermined number of dubbing, the content management unit 251 can notify the mobile terminal that has made the take-out reservation a warning.

  When the program D is taken out more than necessary, the dubbing count counting unit 251a of the program D controls the take-out restriction unit 251c of the program D and prohibits the program D from being taken out. This prohibition process may be executed when a take-out reservation for the content of the program D is made, and the notification may be made to the mobile terminal.

  In addition, a designation unit 251d for registering a portable terminal for which transmission of the program D is prohibited may be provided. For example, when the program D is a program that the child does not want to show to the child, the identification code of the child portable terminal 700C can be designated as the transmission-prohibited portable terminal of the program D.

  In addition, although the example in which the restriction and management of the number of contents to be taken out are performed for the program D has been described, other programs are also managed, that is, the number of contents to be taken out and the restriction are managed for each program.

  Although several embodiments of the present invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention.
