These keys are input by a user operation. Then, a signal corresponding to the operation content is generated, and the generated signal is output to the control unit 12.

  Next, the control unit 12 will be described in detail. FIG. 2 is a block diagram illustrating a schematic configuration of the control unit 12. The control unit 12 is a processing unit (main processor, CPU) that performs overall control of each unit based on signals input and transmitted from each unit, and includes at least an operating system (hereinafter referred to as “OS”) 40 and a one-segment program. A service 42, a one-segment application 44, a browser 46, and a navigation application 50 are included. The OS 40 is a base application that manages the state of each application software. In addition to the above-described units, the control unit 12 also includes execution units for applications that control the operation of various application software, such as mailers, schedulers, phone book applications, and game applications. For simplicity of explanation, it is expressed that the control unit 12 has the above-described functional units. However, it goes without saying that each function unit is actually executed by the control unit 12 executing various programs stored in the memory unit 24.

  The one seg service (broadcast wave storage processing unit) 42 outputs the data broadcast data output from the coprocessor 22 to the one seg application 44 and writes the recorded data in the memory unit 24. Note that the recording data includes video data and audio data. The one-seg service 44 secures a predetermined storage capacity (hereinafter also simply referred to as “capacity”) from the free capacity of the memory unit 24 as a reserved area when another application software requests to secure the capacity. Recording data is not stored in the reserved area that is secured, that is, recording data is not written.

  The one-segment application 44 is application software that selects and controls a TV program to be viewed and a TV program to be recorded based on a user operation. The one seg application 44 controls the operation of the one seg tuner 20 so as to receive the broadcast wave of the TV program of the channel selected by the user, and displays the data broadcast supplied from the one seg service 42 according to the user operation. 26 is displayed.

  The browser 46 is application software that acquires a Web page by connecting to an external computer network via the communication unit 14. The browser 46 downloads data from the computer network by a user operation, and stores the downloaded data in the memory unit 24.

  The navigation application 50 is connected to an external computer network (communication network) via the communication unit 14, acquires map data, route information, congestion information, etc., and displays a route from the current location to the destination to the user, or audio Application software to guide. When the navigation application 50 is not used, the program is stored in the internal memory 24a of the memory unit 24. When the navigation application 50 is used, the program is developed in a processing area of the control unit 12, that is, a cache memory or the like. After that, the navigation application 50 stores the data expanded in the processing area in the memory unit 24 again when the use is finished. At this time, the navigation application 50 also stores newly input data and acquired data in the memory unit 24 during use. In addition, the navigation application 50 displays the operation screen, search results, and the like on the display unit 26 or outputs sound from the speaker 28 while storing all or part of the acquired data in the memory unit 24. That is, the navigation application 50 writes data in a part of the memory unit 24 even when used by the user. Here, as data stored in the memory unit 24 by the navigation application 50, navigation data including a route or a destination is exemplified. In the navigation data, an upper limit value of the data capacity is set. That is, the navigation application 50 is preset with an upper limit value of an increase capacity of data stored in the memory unit 24 by one use. If the one-segment service 42 is recording a program when an activation instruction is input from the user, the navigation application 50 is activated after securing a predetermined capacity in the memory unit 24. This will be described in detail later.

  Next, the operation of the mobile terminal device 10 will be described. FIG. 3 is a sequence diagram illustrating an example of a processing operation of the mobile terminal device 10. Here, the example shown in FIG. 3 is a case where there is a margin in the remaining capacity of the memory unit for the TV program to be recorded.

  First, as step ST10, an instruction for recording a predetermined television program on a predetermined channel is input to the one-segment application 44 by a user operation, and an instruction to start recording is input from the one-segment application 44 to the one-segment service 42. The one-segment service 42 inputs a recording start instruction to the coprocessor 22 when a recording start instruction is input, and generates recording data of a predetermined television program. In addition, when recording starts, the one-segment service 42 registers in the OS 40 the terminal state, that is, the state in which the television program is being recorded by the one-segment service 42, in step ST12.

  Next, the one-segment service 42 buffers the recording data output from the coprocessor 22 in the cache memory of the control unit 12 in step ST14. Here, in this embodiment, the cache memory is a buffer. After that, when the recording data output from the coprocessor 22 is buffered for a certain time, the buffered recording data is written in the memory unit 24 as step ST16. The one-segment service 42 repeats the buffering in step ST14 and the writing in step ST16 until the recording is completed, interrupted, or a new instruction from another part is input.

  Next, while the one-segment service 42 is recording a television program, an instruction to activate the navigation application 50 is input from the input unit 30 by the user as step ST18.

  When the activation instruction is input, the navigation application 50 detects the remaining size of the memory unit 24, that is, the free space from the OS 40, and confirms the remaining memory capacity in step ST20. The browser 46 determines whether or not the navigation application 50 can be activated by checking the remaining capacity (that is, the remaining size) of the memory unit 24. If the remaining capacity of the memory unit 24 is less than the capacity that may increase when the navigation application 50 is terminated, the display unit 26 displays that the capacity of the memory unit 24 is insufficient, and the navigation application 50 The process is terminated without starting. That is, when there is a possibility that the data of the navigation application 50 cannot be written in the memory unit 24 at the end, the navigation application 50 is not activated.

  When the navigation application 50 detects that it can be activated in step ST20, the navigation application 50 acquires terminal state information from the OS 40 in step ST22. When the navigation application 50 acquires that the one-segment service 42 is recording from the acquired terminal state, the navigation application 50 sends a capacity securing request to the one-segment service 42 as step ST24. Here, the capacity securing request means that an empty area for the capacity used by the navigation application 50 is stored in the storage area of the memory unit 24 so that the navigation application 50 can write data to the memory unit 24 when the navigation application 50 is operated and terminated. This is an instruction that requires securing. Here, the capacity used by the navigation application 50 is the upper limit value of the capacity of the navigation data described above.

  When the one-segment service 42 receives a capacity securing request from the browser 46, the one-segment service 42 starts a recording-in-progress determination process as step ST26. The recording determination process will be described in detail later. In the recording determination process, the one-seg service 42 sets an area larger than the capacity of data that the navigation application 50 may write in the free area of the memory unit 24 as a recording data reserved area (write-inhibited area). Secure. Thereafter, the one-segment service 42 sends information indicating that the capacity has been secured to the navigation application 50 as step ST28. After confirming that the capacity is secured in the memory unit 24 by the one-segment service 42, the navigation application 50 operates the navigation application 50 as step ST30. After that, the navigation application 50 writes data in the memory unit 24 as step ST32 when the navigation application 50 ends. Further, the navigation application 50 writes data in the memory unit 24 as needed not only at the time of termination but also during operation. The navigation application 50 writes data to the memory unit 24 when the one-segment service 42 is not writing to the memory unit 24. When the data writing is completed, the navigation application 50 sends an instruction to cancel the capacity securing request to the one-segment service 42 in step ST34. The one-seg service 42 ends the recording-in-progress determination process when an instruction to cancel the capacity securing request is sent from the navigation application 50, and repeats the recording data buffering in step ST14 and the recording data writing in step ST16. Further, the one-segment service 42 ends the recording when the recording of the designated television program is completed, when the recording for the designated time is completed, or when the free space in the memory unit 24 is exhausted.

  Next, the recording determination process in step ST26 of the one-segment service 42 will be described in detail. FIG. 4 is a flowchart showing an example of processing steps of the recording determination process. First, as step ST40, a capacity securing request is input from the navigation application 50 to the one-segment service 42. In addition, this step ST40 is the same step as step ST24 mentioned above. Next, the one-segment service 42 reserves the reserved capacity size A as a reserved area in the free area of the memory unit 24 in step ST42. Here, the reserved capacity size A may be increased by operating a capacity that is larger than the capacity that can be used by the navigation application 50 (that is, the upper limit value of the capacity of navigation data), that is, by operating the navigation application 50. The capacity is more than the data capacity. The one seg service 42 secures the recording portion from the one seg service 42 as a write-in prohibition in the capacity portion corresponding to the secured capacity size A among the free capacity in the memory unit 24, so that the corresponding free area in the memory unit 24 Is a reserved area. Next, the one-segment service 42 detects the remaining size B in the memory unit 24 and the size C of the buffered recording data as step ST44. Here, the remaining size B in the memory unit 26 is a pure free area at the time of detection that does not consider the presence or absence of the reserved capacity size A. That is, the remaining size B is a size including the reserved capacity size A.

  Next, in step ST46, the one-segment service 42 determines whether the size obtained by subtracting the reserved capacity size A from the remaining size B is larger than the size C of the buffered recording data, that is, B−A> C. Determine whether. If the one-segment service 42 determines in step ST46 that B−A ≦ C, it determines that the buffered data cannot be written to the memory unit 24, and proceeds to step ST48. If the one-segment service 42 determines in step ST46 that B−A> C, the one-seg service 42 determines that the buffered recording data can be written to the memory unit 24, and proceeds to step ST52. The example shown in FIG. 3 is a case where the remaining size B has a margin, so the one-segment service 42 proceeds from step ST46 to step ST52.

  If the one-segment service 42 determines in step ST46 that the recording data cannot be written in the memory unit 24, in step ST48, the one-seg service 42 inputs a recording stop request to the coprocessor 22 and stops generating the recording data of the received TV program. . Thereafter, in step ST50, the one-segment service 42 performs a recording end process and ends the recording of the television program by the one-segment service 42.

  If the one-segment service 42 determines in step ST46 that the recording data can be written in the memory unit 24, the buffered recording data is written in the memory unit 24 in step ST52. Thereafter, the one-segment service 42 determines whether an instruction to cancel the capacity securing request is input from the navigation application 50 in step ST54. If the one-segment service 42 determines in step ST54 that the cancel instruction has not been input, the one-seg service 42 proceeds to step ST44, and continues recording data recording while securing the reserved capacity size A in the memory unit 24. If the one-seg service 42 determines in step ST54 that a cancel instruction has been input, the one-seg service 42 ends the recording determination process and returns to normal one-seg service recording.

  In this way, the mobile terminal device 10 allows the one-seg service 42 to reserve a free space equal to or larger than the upper limit of the navigation data capacity as a reserved area in the memory unit 24 based on the capacity securing request. Can be written and stored in the memory unit 24 from other application software (in this embodiment, the navigation application 50 as an example). For example, while recording a television program in the background, that is, while displaying the received television program on the display unit 26, the recorded data is buffered and written to the memory unit 24, while data of other application software is recorded. Can also be written to the memory unit 24. As a result, it is necessary to write data to the memory unit 24 at the time of use or termination (that is, the use capacity of the memory unit 24 changes as a result of use), and thus cannot be used in a situation where writing to the memory unit 24 is not possible. The application software can also be used simultaneously with the one-segment service 42. Therefore, the number of application software that can be used during the recording of a television program is increased, the use restriction by the user can be reduced, and the usability as a portable terminal device can be improved. Note that recording of a television program in the background may be set to start recording by a timer or the like. Moreover, the portable terminal device 10 may display an image displayed by other application software on the display unit 26 when a TV program is recorded in the background. That is, a TV program may be recorded in the background while other application software is processed in the foreground.

  Further, the present invention is not limited to recording in the background, but can be applied to recording in the foreground, that is, when recording is performed while displaying the program on the display unit 26. As a result, the program can be recorded while being displayed on the display unit 26, and other application software can be operated, and data of other application software can be stored in the memory unit 24.

  In the mobile terminal device 10, the case where the navigation application 50 writes data in the memory unit 24 as application software while the TV program is recorded by the one-segment service 42 has been described. However, the present invention is not limited to this, and the data is stored in the memory. It can be used in the case of various application software written in For example, even when the browser 46 is used, after the predetermined capacity is secured by the one-segment service 42, the browser 46 is activated, so that an image or the like can be downloaded by the browser 46 simultaneously with the one-segment service 42. Similarly, in the case of game application software, a predetermined capacity is secured by the one-segment service 42 so that the data played by the game can be saved. The service 42 can be used simultaneously.

  Here, when there can be a plurality of application software, it is preferable that the capacity of application software that may use the largest capacity in each application is set as a fixed value in advance and set as the reserved capacity size A. In this way, by setting the reserved capacity size A, data can be saved regardless of which application is activated during the recording of a television program by the one-segment service 42.

  In the above embodiment, the reserved capacity size A is set as one value common to a plurality of application softwares. However, the present invention is not limited to this, and the reserved capacity size A may be set for each application software. Here, the correspondence relationship between the application software and the reserved capacity size is stored in advance in the memory unit 24 as a table, a map, or the like, and the one-segment service 42 may read out from the memory unit 24 as necessary. The application software itself may have a correspondence relationship. As a result, the one-segment service 42 can grasp the correspondence between the application software and the reserved capacity size. FIG. 5 is a flowchart showing another example of the processing step of the recording determination process. Here, the flowchart shown in FIG. 5 is the same process as the flowchart shown in FIG. 4 except that a process for determining the secured capacity size is added according to the type of application software. Are denoted by the same step numbers, and detailed description thereof is omitted.

  First, as shown in FIG. 5, a capacity securing request is input from the application software to the one-segment service 42 as step ST40. Thereafter, the one-segment service 42 detects the type of application software that has input the capacity securing request in step ST60. Thereafter, in step ST62, the one-segment service 42 detects the reserved capacity size corresponding to the detected application software from the relationship between the application software stored in the memory unit 24 and the reserved capacity size, and determines the detected reserved capacity size. Set as reserved capacity size A. Thereafter, after the step ST42, the one-segment service 42 performs processing in the same process as the flowchart shown in FIG. 4 described above.

  As described above, by setting the reserved capacity size corresponding to the type of application software, the area that the one-segment service 42 does not write can be limited to the capacity required for each application. As a result, depending on the type of application software to be activated, the capacity of the memory unit 24 that can be written by the one-segment service 42 can be increased, and more recorded data can be written.

  Here, the determination process during recording may be performed as follows in order to cope with the case where the storage of data in the application software is stopped. FIG. 6 is a flowchart showing another example of the processing step of the recording determination process. Here, the flowchart shown in FIG. 6 is the same process as the flowchart shown in FIG. 4 except that a step for determining whether or not the data storage is stopped is added. Are denoted by the same step numbers, and detailed description thereof will be omitted. Further, in the flowchart of FIG. 6, as in the flowchart of FIG. 4, the case where the navigation application 50 is used as application software will be described.

  First, as shown in FIG. 6, a capacity securing request is input from the navigation application 50 to the one-segment service 42 as step ST40. Thereafter, the one-segment service 42 secures the reserved capacity size A requested by the navigation application 50 in the memory unit 24 in step ST42, and is buffered with the remaining size B in the memory unit 24 as step ST44. The size C of the recorded data is detected.

  Next, the one-segment service 42 detects whether an instruction to stop saving is input from the navigation application 50 in step ST70. The instruction to cancel the storage is an instruction indicating that the storage of data that the navigation application 50 is scheduled to write in the memory unit 24 is stopped. For example, when the user ends the processing by the navigation application 50 without saving the ringtone downloaded by the navigation application 50 in the memory unit 24, the ringtone is input from the browser 46 to the one-segment service 42. If the one-segment service 42 detects in step ST70 that a storage stop instruction has been input, it enters 0 in the reserved capacity size A in step ST72, that is, sets A = 0, and proceeds to step ST46. If the one-segment service 42 detects in step ST70 that the instruction to stop saving has not been input, the one-seg service 42 proceeds directly to step ST46. The one-segment service 42 performs processing in steps similar to those in the flowchart shown in FIG. 4 described above after step ST46.

  In this way, when an instruction to cancel storage is input, the capacity that can be used by the one-segment service 42 can be detected appropriately by setting the reserved capacity size A to 0, and the free capacity of the memory unit 24 can be appropriately determined. A television program can be recorded in the detected state, and the memory unit 24 can be used effectively.
