The initial setting unit 113 holds initial settings set in advance by the user. The notification unit 114 notifies the user of the reception of a telephone call or an e-mail by a vibrator, sound, light emission, display, and the like.

  FIG. 2 is a block diagram showing a configuration of a system in which the mobile terminal device according to the embodiment of the present invention is used.

  A system in which the mobile terminal device 100 configured as described above is used is a system for transmitting and receiving telephones, electronic mails, and the like, and includes a base station 200, a network 300 such as the Internet, and a server device 400.

  The server device 400 is a device that records a television broadcast program according to a recording instruction from the mobile terminal device 100. As shown in FIG. 2, the server device 400 includes a transmission / reception unit 401, an authentication unit 402, a control unit 403, a transmission control unit 404, A recording medium 405, a recording control unit 406, a TV broadcast processing unit 407, and a TV broadcast receiving unit 408 are provided.

  The TV broadcast receiving unit 407 receives a television broadcast signal broadcast by a stream such as an MPEG2 transport stream from a broadcast station. The TV broadcast processing unit 408 extracts auxiliary information such as an electronic program guide (EPG) from the stream received by the TV broadcast reception unit 407 and outputs the auxiliary information to the control unit 403.

  The transmission / reception unit 401 performs data transmission / reception and data packet processing. The authentication unit 402 authenticates whether or not the mobile terminal device 100 that has transmitted the instruction to record a television broadcast program is a registered user. The control unit 403 controls the recording and termination of a television broadcast program based on a recording instruction from the mobile terminal device 100 and auxiliary information. The control unit 403 controls transmission of a television broadcast program recorded on the recording medium 405 based on a request from the mobile terminal device 100.

  The transmission control unit 404 reads a television broadcast program stream recorded in the recording medium 405 and transmits the stream to the mobile terminal device 100 via the transmission / reception unit 401. The recording medium 405 is a storage unit such as a hard disk for storing a television broadcast program. The recording control unit 406 records the received television broadcast program on the recording medium 405.

  Next, a description will be given of an operation in the case where the mobile terminal device 100 configured as described above outputs video and audio of a television broadcast (hereinafter also simply referred to as a television broadcast display).

  First, the stream received by the TV broadcast receiving unit 101 is input to the TV broadcast processing unit 102. The TV broadcast processing unit 102 decodes the input stream, and outputs the decoded television broadcast video YUV signal to the display conversion unit 103 at a normal display frame rate (for example, 15 frames / second). Further, the TV broadcast processing unit 102 outputs the decoded audio of the television broadcast to the output control unit 106. The display conversion unit 103 converts the input YUV signal into an RGB signal for each frame and outputs the RGB signal to the output control unit 106. The output control unit 106 outputs the RGB signals of the input television broadcast video to the display unit 107 and outputs the input television broadcast audio to the audio reproduction unit 108. In this way, the television broadcast is displayed on the mobile terminal device 100.

  Next, when the remaining battery level is less than a predetermined amount while the mobile terminal device 100 is displaying a television broadcast, or when the remaining battery level is less than a predetermined amount when the display of the television broadcast is requested The operation will be described.

  FIG. 3 shows the flow of operation when the remaining battery level is less than a predetermined amount during display of a television broadcast, or when the remaining battery level is less than a predetermined amount when a display of the television broadcast is requested. It is a flowchart.

  The control unit 109 determines whether or not the remaining amount of the battery 112 notified from the power management unit 111 is equal to or less than a predetermined capacity (step S101). If the remaining battery level is not less than the predetermined capacity (NO in step S101), the control unit 109 continues to display the television broadcast at the normal display frame rate. In the operation when the display of the television broadcast is requested, the display of the television broadcast at a normal display frame rate is started (not shown).

  On the other hand, if the remaining battery level is less than or equal to the predetermined capacity (NO in step S101), the control unit 109 makes an inquiry about how to display a television broadcast because the remaining battery level is less than or equal to the predetermined capacity. The output control unit 106 is instructed to display in a predetermined area. Upon receiving this instruction, the output control unit 106 displays a message such as “The battery level is low. Please select a process” in a predetermined area of the display unit 107 as shown in FIG. And “1. End of viewing”, “2. Record on server”, “3. Playback with reduced frame rate”, “4. Play only sound”, etc. are displayed (step S102).

  When “1. End of viewing” is selected by the user as an answer to the inquiry (A = 1 in step S103), the control unit 109 displays a television broadcast on the TV broadcast reception unit 101 and the output control unit 106. To finish. Upon receiving this instruction, the TV broadcast receiving unit 101 ends the reception of the television broadcast. In addition, the output control unit 106 deletes the message displayed on the display unit 107 and ends the output of the video and audio of the television broadcast (step S104).

  When “2. Record on server” is selected by the user as an answer to the inquiry (A = 2 in step S103), the control unit 109 records the TV broadcast program currently displayed on the server. Instruct the device. That is, the control unit 109 transmits a recording instruction by designating a broadcast station (channel) of a currently displayed television broadcast program via the transmission / reception processing unit 105 and the wireless unit 104 (step S105). Further, the control unit 109 instructs the TV broadcast receiving unit 101 and the output control unit 106 to end the display of the television broadcast. Upon receiving this instruction, the TV broadcast receiving unit 101 ends the reception of the television broadcast. Further, the output control unit 106 deletes the message displayed on the display unit 107 and ends the display of the television broadcast (step S106).

  FIG. 5 is a flowchart showing an operation flow when the server apparatus 400 records a television broadcast program instructed to be recorded.

  When the server device 400 receives a recording instruction from the mobile terminal device 100 by the transmission / reception unit 401 (step S201), the authentication unit 402 determines whether the mobile terminal device 100 that transmitted the recording instruction is a registered user. The authentication is performed using, for example, the user ID included in the recording instruction (step S202). As a result of the authentication, if the mobile terminal device 100 that has transmitted the recording instruction is authenticated as a pre-registered user (YES in step S202), the control unit 403 displays the program of the broadcast station designated by the recording instruction. The recording control unit 406 is instructed to start recording. Receiving this instruction, the recording control unit 406 records the stream received by the TV broadcast receiving unit 407 on the recording medium 405 (step S203).

  At this time, the control unit 403 refers to auxiliary information such as an electronic program guide (EPG) extracted by the TV broadcast processing unit 408 to obtain the end time of the program of the broadcast station specified by the recording instruction. (Step S204). Next, the control unit 403 instructs the recording control unit 406 to end the recording of the program being recorded at the end time of the program being recorded. Receiving this instruction, the recording control unit 406 ends recording of the program being recorded onto the recording medium 405 (step S205). Next, the control unit 403 notifies the portable terminal device 100 that the recording of the program of the broadcast station designated by the recording instruction has been completed (step S206).

  Further, as a result of the authentication (step S202), when the mobile terminal device 100 that has transmitted the recording instruction is not a pre-registered user and is not authenticated (NO in step S202), the control unit 403 issues a recording instruction. The transmitted mobile terminal device 100 is notified that user authentication has not been performed (step S207).

  On the other hand, when the mobile terminal device 100 receives from the server device 400 a notification indicating that the user authentication has not been performed or a recording completion notification of the designated program, the mobile terminal device 100 instructs the output control unit 106 to display that fact. Upon receiving this instruction, the output control unit 106 displays a message such as “user authentication has not been performed” or “recorded television broadcast program has been recorded on the server device” on the display unit 107.

  When the user selects “3. Play at a reduced frame rate” as the answer to the inquiry (A = 3 in step S103), the control unit 109 is currently displaying on the TV broadcast processing unit 102. The display frame rate (for example, 15 frames / second) of the TV broadcast video is reduced to a predetermined display frame rate (for example, 7.5 frames / second, which is 1/2 of the normal display frame rate), and is output. Instruct. Receiving this instruction, the TV broadcast processing unit 102 reduces the decoded normal display frame rate to a predetermined display frame rate and outputs it to the display conversion unit 103. The display conversion unit 103 converts the input YUV signal that has been reduced to a predetermined display frame rate into an RGB signal for each frame, and outputs the RGB signal to the output control unit 106. The output control unit 106 deletes the message displayed on the display unit 107, and displays a television broadcast video with a reduced display frame rate on the display unit 107 (step S107). At this time, the TV broadcast processing unit 102 may reduce the display frame rate by decoding only one picture, for example, only I pictures or only I pictures and P pictures.

  Further, when “4. Play only sound” is selected by the user as an answer to the inquiry (A = 4 in step S103), the control unit 109 provides the current information to the TV broadcast processing unit 102 and the output control unit 106. An instruction is given to stop the display of the TV broadcast image being displayed. Upon receiving this instruction, the TV broadcast processing unit 102 stops decoding the stream related to the video among the streams received by the TV broadcast receiving unit 101. In addition, the output control unit 106 deletes the message displayed on the display unit 107 and stops the output of the video of the television broadcast (step S108). At this time, the TV broadcast processing unit 102 continues to decode the stream related to the audio among the streams received by the TV broadcast receiving unit 101 and continues to reproduce the audio of the television broadcast in the audio reproduction unit 108. To do.

  As described above, if the remaining battery level is lower than the specified level during TV broadcast display, or if the remaining battery level is lower than the predetermined level when the TV broadcast display is requested, Since the user is inquired about the operation, the user can select the desired operation.

  Further, when “2. Record on server” is selected, the television broadcast program that has been displayed so far is recorded on the server device 400, so that the power consumption associated with the display of the television broadcast occurs. Instead, the user can view the recorded program later. In addition, the program can be reliably recorded by the server device 400.

  Further, when “3. Playback at a reduced frame rate” is selected, it is possible to reduce the processing amount of display conversion from the YUV signal to the RGB signal in the display conversion unit 103 and to suppress power consumption. Can do.

  In addition, when “4. Play only sound” is selected, the decoding processing of the stream related to the video in the TV broadcast processing unit 102 and the display on the display unit 107 with high power consumption are stopped. Can be suppressed.

  In this embodiment, when the remaining battery level is less than a predetermined amount while displaying a television broadcast, or when the remaining battery level is less than a predetermined amount when a display is requested for a television broadcast. The user is inquired about subsequent operations, but is not limited to this. Of the operations described above, which operation is to be executed can be set in the initial setting unit 113 in advance. Then, based on the content set in the initial setting unit 113, the control unit 109 is configured to display a television broadcast when the remaining battery level is equal to or lower than a predetermined amount, or when the television broadcast is requested to be displayed. What is necessary is just to control operation | movement when the residual amount of a battery is below predetermined amount.

  For example, if “2. Record on server” is set in the initial setting unit 113, the control unit 109 does not make an inquiry to the user and displays the display unit 107 as shown in FIG. 4B, for example. Displays a message such as “The battery level is low, so it is recorded by the server.” And the recording instruction is transmitted to the server device 400.

  Further, for example, if the initial setting unit 113 is set to “3. Playback at a reduced frame rate”, the control unit 109 does not make an inquiry to the user and displays, for example, “Battery remaining”. After the message such as “The amount has been reduced and the frame rate is reduced to play.” Is displayed, and then the television broadcast video with the reduced display frame rate is displayed on the display unit 107.

  For example, if the initial setting unit 113 is set to “1. End of viewing”, the control unit 109 does not make an inquiry to the user, and displays, for example, “the remaining battery level is low. The display on the display unit 107 is stopped after a message such as “The display of the television broadcast is ended.” Is displayed. In this case, without displaying the message on the display unit 107, for example, the notification unit 114 may notify the user that the display of the television broadcast is terminated by a vibrator, sound, light emission, or the like.

  For example, if the initial setting unit 113 is set to “4. Play only sound”, the control unit 109 does not make an inquiry to the user, for example, “the battery level is low. Now, the display of the video is stopped and only the sound is played back ", and then the display on the display unit 107 is stopped. Also in this case, without displaying the message on the display unit 107, for example, the notification unit 114 may notify the user that the display is stopped by a vibrator, sound, light emission, or the like.

  Also, in the present embodiment, when the remaining battery level is less than a predetermined amount while displaying a television broadcast, or when the remaining battery level is less than a predetermined amount when a display is requested for a television broadcast. In the subsequent operation, the user is asked which one of the four methods to select, but this is not to select only one but to select a combination from the four methods. Also good. For example, if “2. Record on server” and “3. Play with reduced frame rate” are selected, the control unit 109 instructs the server device to record the TV broadcast program that is currently displayed, and An instruction is given to reduce the display frame rate of the currently displayed television broadcast video to a predetermined display frame rate. Thus, while the television broadcast program currently displayed on the server device is recorded, the user can continue to view the currently broadcast program on the portable terminal device until the remaining battery level is exhausted. The same effect can be obtained even when “2. Record on server” and “4. Play only sound” are selected. This also applies to the case where the initial setting unit 113 is set in advance.

  Further, in the present embodiment, the server apparatus 400 is described as being present on the network, but may be present at the user's home, for example. In this case, the server device 400 can be realized by, for example, a home gateway and an HDD recorder. In addition, since the mobile terminal device 100 includes an interface such as a memory card, for example, a program recorded from an HDD recorder can be directly copied or moved to the memory card, and the program can be reproduced from the memory card.

  In the present embodiment, the end time of the program being recorded by the server device 400 is acquired. However, the present invention is not limited to this. For example, the recording instruction from the mobile terminal device 100 may be transmitted including the end time.

  In this embodiment, when the playback is performed with the frame rate lowered, the display frame rate is reduced to a predetermined display rate. However, the present invention is not limited to this. For example, after the control unit 109 has a plurality of thresholds for the remaining battery level and first reduces the display frame rate to a predetermined display frame rate (for example, 7.5 frames / second that is ½ of the normal display frame rate). In addition, the display frame rate is stepwise according to the remaining battery level (for example, 5 frames / second, which is 1/3 of the normal display frame rate, and 3 frames / second, which is 1/5 of the normal display frame rate). It may be lowered.

  Further, in the present embodiment, the operation when the power management unit 111 detects the remaining battery level of the battery 112 and the remaining battery level becomes equal to or less than a predetermined amount while displaying a television broadcast, for example, is described. However, it is not limited to this. For example, the power management unit 111 may detect the battery consumption instead of the battery remaining amount of the battery 112, and perform the above operation when the battery consumption becomes a predetermined amount or more while displaying a television broadcast, for example. I do not care.

  Further, in this embodiment, the TV broadcast using a stream such as an MPEG2 transport stream has been described as an example. However, the TV broadcast receiving units 101 and 408 and the TV broadcast processing units 102 and 407 receive and reproduce analog broadcasts. Also good.

  Further, in the present embodiment, the operation when the power management unit 111 detects the remaining battery level of the battery 112 and the remaining battery level becomes equal to or less than a predetermined amount while displaying a television broadcast, for example, is described. However, even if the remaining battery level is less than or equal to the predetermined amount, if the external power supply is supplied, the same operation as when the remaining battery level is equal to or greater than the predetermined amount may be performed. .

  Each functional block in the block diagram shown in FIG. 1 is typically realized as an LSI which is an integrated circuit. This LSI may be made into one chip or a plurality of chips. (For example, the functional blocks other than the memory may be integrated into one chip.) Although the LSI is used here, it may be referred to as an IC, a system LSI, a super LSI, or an ultra LSI depending on the degree of integration.

  Further, the method of circuit integration is not limited to LSI, and implementation with a dedicated circuit or a general-purpose processor is also possible. An FPGA (Field Programmable Gate Array) that can be programmed after the manufacture of the LSI or a reconfigurable processor that can reconfigure the connection and setting of the circuit cells inside the LSI may be used.

  Further, if integrated circuit technology comes out to replace LSI's as a result of the advancement of semiconductor technology or a derivative other technology, it is naturally also possible to carry out function block integration using this technology. Biotechnology can be applied.

  Further, each functional block of the block diagram shown in FIG. 1 and the flowchart shown in FIG. 3 are realized by a processor and a program at the central part thereof.

  As described above, the mobile terminal device according to the present invention is suitable for a mobile terminal device that can receive and display a television broadcast. For example, the mobile terminal device is suitable for a mobile phone with a TV, a PDA with a TV (Personal digital assistant), and the like. Yes.
