The configuration and operation of the embodiment will be described below for each of these functions.

(1) Function for greatly moving the position of the pointer by a simple key operation or increasing the moving speed: FIG. 1 is a block diagram for explaining a configuration for realizing this function. FIG. 3 is a flowchart for explaining the processing, and FIG. 4 is an explanatory diagram for explaining the system operation of this function. Here, each configuration in the block diagram of FIG. 1 is one of programs executed on a processing device including hardware in the mobile phone 10 or STB 20, a CPU (central processing unit), a storage device, etc. (not shown). Or it is constituted by combination. Further, a display device such as a TV monitor is connected to the STB 20, and pointer display and image display can be performed by executing various applications on the screen of the display device.

  As shown in FIG. 1, in the present embodiment, other keys 16 such as a cross key 12, a center key 13 and a numeric keypad, an input control unit 101, a remote control code control unit 102, and a good infrared signal emission are included in the mobile phone 10. The remote control code information 104, the mobile phone identification ID 105, and the transmission timing information 106 are stored in a predetermined storage device. The input control unit 101 detects the on / off states of the keys 12 to 16 and outputs the detected key information as key code information. The remote control code control unit 102 reads the remote control code corresponding to the key code input based on the output signal of the input control unit 101 from the remote control code information 104, adds the mobile phone identification ID 105, and prevents competition with other remote controls. Therefore, the timing is adjusted based on the transmission timing information 106, and the information is transferred to the infrared light emitting unit 103. The infrared light emitting unit 103 outputs an infrared signal modulated in a predetermined format based on the input information as a remote control signal.

  As shown in FIG. 18, the remote control code information 104 is information in which the key code of each key (cross key, center key, numeric keypad, specific key) is associated with the remote control code. In the example shown in FIG. 18, the remote control codes “011”, “012”, “013” are added to the key codes “01” to “04” generated in response to pressing of the cross keys 12u, 12d, 12r, and 12l in FIG. ”And“ 014 ”, and the remote control code“ 021 ”corresponds to the key codes“ 01 + 99 ”to“ 04 + 99 ”generated in response to simultaneous pressing of the menu key 14 and the cross keys 12u, 12d, 12r, and 12l in FIG. ”,“ 022 ”,“ 023 ”,“ 024 ”, the remote control code“ 055 ”corresponds to the key code“ 55 ”generated in response to pressing of the center key 13, and a clear key (not shown) The remote control code “066” corresponds to the key code “66” generated in response to the pressing of the key, and the key code generated in response to the pressing of the 9th key 159 in the numeric keypad 15. Remote control code "190" is set to correspond to "19".

  The mobile phone identification ID 105 is identification ID information given to the mobile phone. As shown in FIG. 19, the transmission timing information 106 is information indicating basic period information indicating the basic period time of remote control signal output, offset time for determining the remote control signal transmission time, and transmission possible time. The basic cycle information is one cycle when time-division control is performed on a single STB for the transmission possible periods of a plurality of mobile phones. In the example of FIG. The basic period is set (that is, the basic period of 1 second is divided into four time slots and time-division control is performed). The offset time is information indicating the output start time of the remote control signal in each cycle when the basic cycle clock signal of the mobile phone 10 is used as a reference. The transmission possible time indicates the time that can be continuously output from the remote control signal output start time determined by the offset time. In the example of FIG. 19, a signal can be output after 200 ms from the start time of the basic period of 1 second, and can be continuously output until after 400 ms (= 200 ms + 200 ms). A method for setting each information will be described later.

  On the other hand, the STB 20 of FIG. 1 includes an infrared signal light receiving unit 201, a remote control code analyzing unit 202, a pointer control unit 203, an action processing unit 204, a pointer drawing unit 205, an application 206, and an operating system 207, and a predetermined memory. A mobile phone identification ID registration table 208, remote control code information 209, action information 210, and pointer state information 211 are stored in the apparatus. The infrared signal light receiving unit 201 demodulates the received infrared signal, converts it into a remote control code, and outputs it. The remote control code analysis unit 202 refers to the mobile phone identification ID registration table 208 and the remote control code information 209, determines the mobile phone identification ID, analyzes the remote control code, and sends the determination result and analysis result to the pointer control unit 203. Take over.

  As shown in FIG. 20, the mobile phone identification ID registration table 208 is composed of a TS allocation number, a mobile phone identification ID, and priority information. The TS allocation number is a number for identifying a time division control time slot used when a plurality of mobile phones 10 are used simultaneously. The priority is information indicating the priority order among the mobile phones 10 and is used when a difference in operating conditions such as a pointer is provided between the plurality of mobile phones 10. The mobile phone identification ID registration table 208 is set by performing a registration operation from each mobile phone 10 on the STB 20 prior to the remote control operation (details will be described later). In the example shown in FIG. 20, mobile phone identification IDs are registered for “01” to “03” among TS allocation numbers “01” to “04”, and have priority over TS allocation number “01”. The degree “0” is set, and the priority “3” is set for the others. In this example, “0” has the highest priority, and “1”, “2”, “3”,...

  As shown in FIG. 21, the remote control code information 209 is composed of information indicating a remote control code, a pointer instruction code, designated coordinates, and a movement amount. The remote control code has a value corresponding to the remote control code information 104 on the mobile phone 10 side shown in FIG. 18, and each key (cross key, center key, numeric keypad, specific key, or their key) operated on the mobile phone 10 side. A predetermined combination of keys). The pointer instruction code is a predetermined code indicating an operation instruction when an instruction to move the pointer or click the pointer is performed on the remote control code, and is set for each application executed in the STB 20. The designated coordinates are values when the pointer is immediately moved to a predetermined position on the screen. The movement amount is a value indicating the amount by which the pointer is moved by one operation. In the example of FIG. 21, for example, a pointer instruction code “111” (upward movement) and a movement amount “5” are set for the remote control code “011” corresponding to the operation of the cross key 12u (see FIG. 4). For the remote control code “021” corresponding to the simultaneous operation of the key 12u and the menu key 14 (see FIG. 4), the pointer instruction code “121” (upward movement) and the movement amount “10” are set. A pointer instruction code “219” (designated movement) and designated coordinates “300, 300” are set for the remote control code “190” corresponding to the operation of the key 159 (see FIG. 4).

  On the other hand, the pointer control unit 203 in FIG. 1 accesses the action information 210 and the pointer information 211 based on the information analyzed by the remote control code analysis unit 202, sets / updates the pointer state information, and updates the action information. Processing is performed to take over the determined action information or the latest pointer state information to the action processing unit 204 and the pointer drawing unit 205.

  The action information 210 is used to transmit an event message to the pointer drawing unit 205 or the operating system 207 via the action processing unit 204 or the pointer drawing unit 205 based on the pointer instruction code inherited from the remote control code analysis unit 202. There is information used. That is, information for converting a pointer instruction code into an action for starting a menu or selecting / executing a button is set. For example, as shown in FIG. 22, in this action information 210, action information to be transferred to the action processing unit 204 and the pointer drawing unit 205 is set for the case where the application 206 has been activated and the case where it has not been activated. . In the example shown in FIG. 22, for the pointer instruction code “155” (when the center key 13 is pressed), when the application 206 has been activated, “mouse left click instruction” indicating selection or determination is not yet displayed. In the case of activation, “mouse right-click instruction” which means an instruction to display an application menu is set.

  For each TS allocation number, the pointer status information 211 includes information on whether or not it is being activated (displaying the pointer), information on whether or not it is in the full screen table, status change time, pointer current position information, etc. It is a table for storing a state. For example, as shown in FIG. 23, a flag indicating the presence or absence of active display or full-screen display, state change time, and pointer position information expressed in xy coordinates are registered corresponding to each TS allocation number.

  Further, the action processing unit 204 transmits an event message to the application 206 and the operating system 207 in accordance with the action information transmitted from the pointer control unit 203. The pointer drawing unit 205 transmits to the operating system 207 an event message for drawing the pointer cursor according to the action information and the pointer state information.

  Next, the processing procedure of the configuration shown in FIG. 1 will be described with reference to the flowcharts of FIGS. 2 and 3 and the system diagram of FIG. In this example, it is assumed that the operation of each key on the mobile phone 10 corresponds to the following function in the screen display by the STB 20.

 (A) Cross key 12: Gives movement direction information in the X-axis or Y-axis direction when the pointer cursor is moved.

 (A) Center key 13: When there is an application (AP) (that is, a predetermined icon of the application, etc.) at the coordinate position of the pointer cursor, a role of execution action (double mouse click, left click) is given.

 (C) The numeric keys 15: 1 to 9 are overlapped with the TV screen 31. For example, when the “9” key 159 is pressed, the pointer cursor 4 is momentarily moved to the lower right portion 309 (see FIG. 4) of the TV screen 31. Give the role to move in.

 (D) Specific key: A key other than the above (here, the menu key 14) is given a role of changing the XY axis moving speed (moving amount is increased or decreased), or the remote controller of the mobile phone 10 having a high priority The function of screen switching is given to the function. When changing the movement amount, for example, the remote control code information 104 is set so that a remote control key with an increased movement amount is assigned when the cross key 12 and the menu key 14 are pressed simultaneously.

  FIG. 2 is a flowchart showing a processing procedure on the mobile phone 10 side. On the mobile phone 10 side, when a predetermined application is activated and the remote control function is activated, the operation state of each key is repeatedly monitored (steps S11 to S12 in FIG. 2). If there is ON information for each key (“Yes” in step S12), the remote control code corresponding to each key code is read from the remote control code information 104, and a mobile phone identification ID is given to this (step S13). Next, the offset time is extracted from the transmission timing information 106 so that the transmission signal does not compete with other remote controllers, the transmission time is calculated from the mobile phone current time, and the transmission information is transmitted to the infrared light emitting unit 103 at that timing. (Step S14). Then, the generated remote control code information is transmitted from the infrared light emitting unit 103 (step S15).

  On the other hand, on the STB 20 side, an infrared signal is received by the infrared light receiving unit 201 (step S21 in FIG. 3), monitored by the remote control code analyzing unit 202, and checked against the remote control code information 209 every time it is received, and remote control code analysis is performed. Is performed (step S22). Specifically, the remote control code analysis unit 202 reads a pointer instruction code, a movement amount, and designated coordinates corresponding to the received remote control code information, and generates information to be taken over for subsequent processing. The remote control code analysis unit 202 also extracts the mobile phone identification ID from the analyzed remote control code information, determines whether it is a registered identification ID (step S23), and if registered, proceeds to step S24. On the other hand, if it is not registered, the process ends ("No" from "No" in step S23). The mobile phone identification ID needs to be registered with the STB 20 in advance, and details of the registration method will be described later.

  Next, the pointer control unit 203 refers to the pointer state information 211 to determine whether the mobile phone identification ID has been activated (step S24). If it has been activated, the pointer state information is read, and then XY is determined by the pointer instruction code. The axis movement direction is determined, and the pointer state information 211 is updated according to the movement amount. If not started, an initial value is set at the current pointer position, and the pointer state information 211 is updated according to the XY axis movement direction and movement amount (step S26). Here, depending on the pointer instruction code, the amount of movement may be increased, or the coordinates to move may be specified.

  Next, the pointer drawing unit 205 draws the pointer cursor based on the current position information, the XY axis movement direction and movement amount, and the designated coordinates, and collates the received remote control code information with the action information 210 to obtain action information. Is included, a message is sent as an event to the corresponding application (AP) 206 and operating system (OS) 207 (step S27).

  As a result of the above processing, as shown in FIG. 4, the screen of the TV monitor 30 is operated by operating the cross key 12, the center key 13, the menu key 14, the numeric keypad 15, and the like using the remote control function of the mobile phone 10. Information for controlling the pointer cursor 4 (4a, 4b) displayed on the display 31 is converted from the mobile phone 10 into remote control code information, transmitted as an infrared signal, and received by the STB 20 to receive the pointer cursor 4 on the TV monitor 30. Move and click. By overlapping the arrangement of the numeric keypad 15 on the TV monitor screen 31 (that is, by making the numeric keypads “1” to “9” correspond to the screen areas 301 to 309), for example, when the numeric keypad “9” 159 is pressed, the TV screen is displayed. The mouse pointer 4 immediately moves to the lower right area 309 of 31 and can perform a rough movement. Next, a detailed movement can be performed with the cross key 12. In addition, the movement speed of the mouse pointer can be changed by pressing the cross key 12 while keeping pressing a specially designated key (the menu key 14 in this example). The pointer 4a represents movement at the same time when the menu key 14 is not pressed, and the pointer 4b represents movement when the menu key 14 is pressed.

(2) Function for shifting the transmission timing of a remote control signal (infrared signal) transmitted from a mobile phone to an STB when using a plurality of mobile phones simultaneously: FIG. 5 shows an overview of this function FIG. FIG. 5 shows an example in which three mobile phones 10a, 10b, and 10c are simultaneously used for one STB 20. The transmission time of the remote control signal from the mobile phone 1 (10a), the mobile phone 2 (10b), and the mobile phone 3 (10c) is in the period TS1, TS2, and TS3 using the time information inside each mobile phone. Split control is performed. In the example of FIG. 5, the period TS4 is not used, but this is repeated with four time lots (TS) of TS1 to TS4 as one cycle. On the screen 31, a pointer 4a corresponding to the mobile phone 1 (10a), a pointer 4b corresponding to the mobile phone 2 (10b), and a pointer 4c corresponding to the mobile phone 3 (10c) are displayed. Each pointer 4a-4c moves according to remote control operation of each mobile phone 10a-10c, or performs a click instruction. In the example of FIG. 5, the pointers can be identified by displaying circled numbers “1” to “3” on the pointers 4 a to 4 c. However, in addition to numbers, images and characters may be displayed, the pointer cursor itself may be an arrow with a different shape (color), or an image other than an arrow.

  A configuration for realizing this function is shown in FIG. Note that the same reference numerals are used for the same components as those in FIG. 1 (hereinafter, the same applies to other drawings). The communication data control unit 120 shown in FIG. 6 receives TS (time slot) allocation information and basic period information from the STB 20 by infrared communication, and generates transmission timing information 106. The clock time information 121 is a storage device that stores information representing the time generated by the clock function provided in the mobile phone 10. The communication data control unit 220 in the STB 20 transmits the TS allocation start time, the transmittable time, and the basic period information in order to synchronize the remote controllers of the mobile phones 10a, 10b,. The synchronization information 230 is information indicating basic cycle information, mobile phone identification ID registration number upper limit value, automatic registration availability information, and transmission possible time (see FIG. 25). Here, the basic period information is a repetition period of time-division control, and the transmittable time is a signal transmittable time in each TS. The communication data control unit 220 assigns a different TS for each mobile phone identification ID.

  Next, the processing procedure of the configuration shown in FIG. 6 will be described with reference to the flowcharts of FIGS. 7 and 8 and the system diagram (FIG. 9) showing the detailed processing of transmission timing information 106 generation. In order to establish time-division control, the time information of each mobile phone 10a, 10b,... Needs to be synchronized. In the present embodiment, the difference information is detected by each mobile phone using the time information of the STB 20 as a reference, and the mobile phone is synchronized by recording this difference information. Apart from this, synchronization of each mobile phone can be established by performing infrared communication or the like between the mobile phones. However, for example, when the clock information cannot be matched directly due to restrictions on the authority of the application executed on the mobile phone, the difference information and the clock information are synchronized as in the present embodiment. Is effective.

  7 and 8 (the steps in FIGS. 7 and 8 are related to each other), the STB 20 and the infrared transmission / reception unit of the mobile phone 10 are made to face each other, and then the STB 20 or the mobile phone by the user, for example. When a predetermined operation is performed on the mobile phone 10, infrared communication is started between the mobile phone 10 and the STB 20, and a communication path is established (step S31 in FIG. 7 and step S41 in FIG. 8). Next, the mobile phone 10 transmits the mobile phone identification ID to the STB (step S32 in FIG. 7).

  Next, when the mobile phone identification ID of the mobile phone 10 is received, the STB 20 determines whether it is a registered mobile phone identification ID in the mobile phone identification ID registration table 208 (step S42 in FIG. 8). If registered, the process proceeds to step S45. However, as a premise, the synchronization information 230 is set with a mobile phone identification ID registration number upper limit value and whether or not automatic registration is possible.

  If unregistered (if “No” in step S42), automatic registration of the synchronization information 230 is possible, and when the mobile phone identification ID registration number upper limit value and the current registration number are determined and there is a vacancy If “Yes” in step S43, the mobile phone identification ID is registered in the mobile phone identification ID registration table 208 (step S44). At the same time, reference is made to data area information 231 by identification ID (details will be described later with reference to FIG. 26), and if the identification ID is not registered, additional registration is performed. If automatic registration is not possible (if “No” in step S43), infrared communication is terminated (step S47 and step S36 in FIG. 7). When the registered state is reached (“Yes” in step S42 or registration in step S44), the TS allocation corresponding to the mobile phone identification ID registration number upper limit, the basic period, and the mobile phone identification ID at the time of registration The TS allocation start time is calculated based on the number, and is transmitted together with information indicating the transmittable time (step S45). Thereafter, the same signal is repeatedly transmitted for every basic period (in this example, every second) (step S46).

  On the mobile phone 10 side, after receiving the TS allocation start time (in this case, time ts2 in FIG. 9) from the STB 20 side (step S33 in FIG. 7 and the procedure (1) enclosed by the balloon in FIG. 9), By receiving information repeatedly from the STB 20 at the basic period, the basic period (according to the clock information on the STB 20 side) is recognized and set in the transmission timing information 106, and the basic period is determined from the clock information on the mobile phone side at that time. Is extracted (step S34 in FIG. 7, procedures (2) and (3) in FIG. 9). Next, the offset time tof at the time on the mobile phone 10 side is extracted from the difference t1 between the received TS allocation start time ts2 and the basic period, and is set in the transmission timing information 106 (steps S35 and FIG. 9 in FIG. 7). (4)). Then, the infrared communication is terminated (step S36 in FIG. 7 and step S47 in FIG. 8).

  At the same time (or at another time) when the TS allocation start time is acquired from the STB 20 side, the mobile phone 10 acquires the transmission possible time (TSe) and sets it in the transmission timing information 106 (FIG. 9). Procedure (5)). The sendable time TSe represents a time during which a signal can be sent, and is a sendable start time (a time after the TS allocation start time ts2 from the basic cycle start time of the STB 20 or an offset time from the time cycle start time of the mobile phone 10). This is the time from the time after tof) until transmission is prohibited.

  Through the above processing, the transmission timing information 106 can be set on the mobile phone 10 side. By using the transmission timing information 106, for example, timing adjustment is performed in step S14 of FIG.

(3) When using a plurality of mobile phones at the same time, the screen of the TV monitor connected to the STB is divided into a plurality of areas, and a plurality of pointers corresponding to the respective mobile phones are limited within the respective areas. A storage device for storing image data consisting of still images and moving images (video) received from a mobile phone is provided in the STB, and each image data is displayed in an area corresponding to each pointer. Or a function of displaying one area of a plurality of divided areas of the TV monitor on the entire screen: FIG. 10 shows a configuration example for realizing this function. In contrast to the configuration shown in FIG. 1, in the configuration shown in FIG. 10, screen movement restriction information 212 is added in STB 20, and part of the internal processing of pointer control unit 203 a is added. Further, a data area 240 for recording image data corresponding to each mobile phone 10 by the operating system 207 (or application 206) is newly illustrated. In addition, the structure which attached | subjected the same referential mark as FIG. 1 consists of the same or substantially the same structure, and abbreviate | omits description.

  In FIG. 10, the pointer control unit 203a sets / updates pointer state information based on the information analyzed by the remote control code analysis unit 202, determines a movement range from the screen movement restriction information 212, determines action information, The processing unit 204 and the pointer drawing unit 205 are taken over. In the screen movement restriction information 212, as shown in FIG. 24, a layout pattern is prepared according to the number of point cursors that are activated, and the restriction area for each TS number has an X / Y coordinate and an X / Y width. Is set. In the present embodiment, as shown in FIG. 12, when a plurality of mobile phones are used, the screen 31 is divided into a plurality of regions (three divisions in FIG. 12), and each region is a dedicated region for a specific mobile phone. A function of providing an area in which the pointers 4a, 4b, and 4c are movable is provided. The area division form differs depending on the number of divisions. In the screen movement restriction information 212 of FIG. 24, the layout pattern “01” when not divided and the layout patterns “02” to “04” when divided into two to four are given. Four layout patterns are set. Then, one to four restriction areas are set for each layout pattern, and each restriction area is associated with each mobile phone by associating each restriction area with a time slot number. For example, as shown in FIG. 12, when the screen 31 is divided into three restricted areas 31a, 31b and 31c, the layout pattern “03” is used, and the coordinate information of each restricted area 31a to 31c is the time slot “TS01 to TS03”. Will be set to the value assigned to.

  Next, the processing procedure of the configuration of FIG. 10 will be described with reference to the flowchart of FIG. The processing procedure on the mobile phone 10 side is the same as that shown in FIG. However, the remote control signal transmission timings of the mobile phones 10a to 10c in step S14 in FIG. 2 are different.

  On the STB 20 side, an infrared signal is received by the infrared light receiving unit 201 (step S501), monitored by the remote control code analyzing unit 202, checked against the remote control code information 209 every time it is received, and remote control code analysis is performed (step S501). S502). Next, it is determined whether it is a registered mobile phone identification ID (step S503). If it has been registered ("Yes" in step S503), the pointer state information 211 is referred to and it is determined whether it is an activated mobile phone identification ID. (Step S504). The mobile phone identification ID that has already been activated is determined based on the mobile phone identification ID corresponding to the TS assigned number in the row where the “active display” in the pointer state information 211 is “1”. This is done by referring to 208.

  When activated ("Yes" in step S504), the full screen display for all pointers in the pointer status information 211 is referred to and it is determined whether there is a pointer being displayed on the full screen (step S505). Here, as shown in FIG. 13, the pointer during full screen display is a display state (lower right in FIG. 13) in which a specific divided area (restricted area 31c in FIG. 13) is displayed on the full screen. In this case, it means that the pointer (in this example, the pointer 4c or 4d) is to be displayed in the specific restricted area (31c) in the full screen display. In FIG. 13, the pointer 4c is a pointer of the mobile phone 10c corresponding to the restricted area 31c, and the pointer 4d is another mobile with high priority that can move to any of the restricted areas 31a to 31c regardless of the area restriction. This is a pointer of the telephone 10d.

  If there is a pointer that is displayed on the full screen (“Yes” in step S505), it is determined whether the pointer matches the currently activated pointer (step S506). If they match (“Yes” in step S506), the process proceeds to step S507. If they do not match (“No” in step S506), the screen is not displayed and the process ends. On the other hand, if there is no pointer being displayed on the full screen (“No” in step S505), the process proceeds to step S507.

  In step S507, the priority identification ID is determined. Here, the priority identification ID is a cellular phone identification ID when the priority corresponding to the cellular phone identification ID in the cellular phone identification ID registration table 208 is less than a predetermined value (less than “1” in the example of FIG. 20). , Corresponding to a pointer that can be moved over the entire restricted area. When the ID is other than the priority identification ID (“No” in step S507), the current pointer instruction code, the designated coordinates, and the movement amount are referred to, and exceed the x width y width range of the corresponding TS allocation in the screen movement restriction information 212. If it exceeds the range, it is changed to a value within the range, and the pointer state information 211 is updated (step S510).

  If it is a priority identification ID (“Yes” in step S507), it is determined whether the pointer instruction code is a screen switch (step S508). The screen switching means an action when a remote control code “066” (clear key (see FIG. 18)) in which the pointer instruction code becomes “166”, for example, is received as shown in FIG. In the example of FIG. 13, when an operation for instructing screen switching is performed on the priority mobile phone 10d, a state in which a plurality of divided restricted areas are simultaneously displayed and one restricted area is displayed in full screen (enlarged display). A function for alternately switching between states is provided.

  When the screen is not switched (“No” in step S508), the pointer state information is updated with the instructed information. In the case of screen switching (“Yes” in step S508), the designated area is restored to full screen display or full screen display (step S509).

  Here, the process of step S509 will be described in detail. When not fully displayed, an area including the coordinates of the current pointer position is extracted from the range of x width and y width of the screen movement restriction information. At this time, the layout pattern to be referenced is determined by the number of pointer status information 211 being activated. Next, YES (“1”) is set in the full-screen display of the pointer status information 211 of the pointer corresponding to the determined area, and other pointers and applications started by the pointer (restricted area) are hidden. A drawing control instruction is set (step S510). On the other hand, during full-screen display, the full-screen display of the pointer status information 211 is set to NO (“0”), and the pointer that was not displayed during full-screen display and the application started by the pointer (restricted area) The drawing control instruction is set so as to be individually displayed again (step S510).

  On the other hand, if it is determined in step S504 that it has not been activated (“No” in step S504), the full screen display of each pointer in the pointer state information 211 is referred to and it is determined whether there is a pointer that is being displayed on the full screen (step S512). If there is a pointer that is being displayed on the full screen (“No” in step S512), the screen is not displayed and the processing is terminated.

  If there is no pointer being displayed on the full screen (“Yes” in step S512), the pointer status information 211 is referred to extract the number of currently active pointers, and the current pointer is newly extracted from the screen movement restriction information 212 based on the number of pointers. Extract the layout pattern when added. The position information of all the pointer status information 211 that is already activated is changed so as to be positioned at the center of the x width y width range of the corresponding TS allocation of the screen movement restriction information 212 (step S513). Next, movement information is set in the pointer status information 211 of the newly added pointer so as to be instructed by the pointer instruction code with reference to the center position of the range of x width and y width specified by the layout pattern (step S514). ).

  In step S511, a pointer cursor or the like is drawn based on the pointer state information and the drawing control instruction. When the pointer instruction code is an action instruction, action information is collated and a message is sent as an event to the corresponding application 206 or operating system 207. For example, if an application activation menu display is set as action information, a list of applications that can be activated is displayed, and an application can be selected and executed by the next action. For example, when the image viewer is selected, the image viewer is activated, and the image data in the data area 240 corresponding to the mobile phone identification ID can be displayed.

  FIG. 12 shows an example of screen division. In the example shown in FIG. 12, the screen 31 is divided into three restricted areas 31a, 31b and 31c. Each restriction area 31a, 31b and 31c corresponds to the mobile phone 1 (10a), the mobile phone 2 (10b) and the mobile phone 3 (10c), and cursors 4a, 4b and 4c are displayed. Further, image information 51, 52, and 53 corresponding to each mobile phone 1 (10a), mobile phone 2 (10b), and mobile phone 3 (10c) is displayed in each restricted area 31a, 31b, and 31c. These image information 51, 52 and 53 are stored in storage areas 241, 242 and 243 allocated to the respective mobile phones 1 (10 a), 2 (10 b) and 3 (10 c) in the data area 240. Corresponds to the image data 51, 52 and 53 stored in the.

  Further, in the example shown in FIG. 13, the cursor 4d of the mobile phone X (10d) set with a higher priority than the three mobile phones 1 (10a), 2 (10b) and 3 (10c) is displayed. An example of starting and switching the screen is shown.

(4) Function that can divide a storage device for storing image data into a plurality of areas and automatically assign each storage area in correspondence with each mobile phone: configuration example for realizing this function 14 shows. Compared to the configuration shown in FIG. 6 or 10, in the configuration shown in FIG. 14, an accumulated data area 130 that is a storage means for image data is added to the mobile phone 10 and the communication data control unit 120 b corresponds to this function. The procedure has been changed to perform the procedure. On the STB 20 side, the identification ID-specific data area information 231 is provided, and the communication data control unit 220b is changed to be capable of controlling the data in the data area 240. In addition, the structure which attached | subjected the same referential mark as another figure is the same or substantially the same structure, and abbreviate | omits description.

  In FIG. 14, the communication data control unit 120b on the mobile phone 10 side performs processing for transmitting the image data in the accumulated data area 130 together with the mobile phone identification ID by infrared communication (see the system diagram of FIG. 17). The accumulated data area 130 stores moving image or still image data. On the other hand, when the communication data control unit 220b on the STB side receives the mobile phone identification ID when receiving data by infrared communication, the STB side communication data control unit 220b determines the mobile phone identification ID for each mobile phone ID in the data area 240 from The address of the data area is acquired, and the received data is automatically stored in the corresponding area. As shown in FIG. 26, the identification ID-specific data area information 231 is obtained by registering address information of identification ID-specific areas (storage areas) 241, 242, 243,... In the data area 240 for each mobile phone identification ID. It is.

  Next, the processing procedure of the configuration of FIG. 14 will be described with reference to the flowcharts of FIGS. 15 and 16. First, infrared communication is started between the mobile phone 10 and the STB 20 to establish a communication path (step S61 in FIG. 15 and step S71 in FIG. 16). Next, the cellular phone 10 transmits the identification ID of the cellular phone (step S62 in FIG. 15).

  When the mobile phone identification ID of the mobile phone 10 is received, the STB 20 determines whether it is a registered mobile phone identification ID (step S72 in FIG. 16), and continues communication if registered, but if not registered Terminates communication (step S75 in FIG. 16 and step S64 in FIG. 15).

  If registered, the mobile phone 10 selects transmission data and transmits it (step S63), and the STB 20 extracts the data area address of the corresponding identification ID from the identification ID-specific data area information 231 (step S73 in FIG. 16). ), The data received from the mobile phone 10 is stored in the corresponding identification ID-specific data areas 241, 242, 243, etc. (step S74 in FIG. 16). And after transmission / reception of data is complete | finished, infrared communication is complete | finished (step S64 of FIG. 15 and step S75 of FIG. 16).

  With the above processing, as shown in FIG. 17, a storage area for each mobile phone is automatically created in the data area 240, and the data automatically transmitted for each mobile phone is accumulated.

  The functions (1) to (4) have been described above. The overall processing procedure is as follows, for example. (A) Data transfer by infrared communication is performed from the mobile phone 10 to the individual allocation area in the data area 240 of the STB 20 (function (4)). (A) At the same time, infrared communication is performed between the mobile phone 10 and the STB 20, synchronization is performed, and different time allocation is performed for each mobile phone 10 (function 2). (C) Signals are transmitted from the plurality of mobile phones 10 to the STB 20, and the plurality of pointer cursors are controlled (function 3). (D) It is also possible to individually display image data or the like in the individual display area (function 3). Note that function (1) can be used in any of (a) to (d).

  According to the present embodiment, the following effects can be obtained. Simultaneous reception of multiple signals of mobile phone remote control signals that can only send one-way signals (cell phone remote control means a mobile phone that can use the remote control signal transmission function) Cannot receive. Therefore, infrared communication (one-to-one two-way communication with a communication distance of about 20 cm) is individually performed in advance between the mobile phone remote controller and the STB, and synchronization is performed, and different time allocation is performed for each mobile phone remote controller. In each mobile phone remote control side, a signal can be transmitted at the timing according to the allocation. Even if a plurality of signals are transmitted at the same time, they are not mixed on the STB side and can be received in order, and apparent simultaneous reception is possible. Multiple infrared remote control signals can be received simultaneously. Therefore, a plurality of mouse pointers can be displayed on the TV monitor and individually controlled. As an advantage that can be individually controlled on the TV monitor, there is simultaneous display of individual data. To realize this, data transfer to the STB individual allocation area by infrared communication and provision of an individual display area on the TV monitor Realize.

  The summary of each function is as follows. (A) By operating the cross key, center key, numeric keypad, etc. of the mobile phone remote controller, information for controlling the pointer cursor is converted into a remote control code, transmitted as an infrared signal, and received by the STB etc. on the TV monitor Move and click the pointer cursor. By overlapping the numeric keypad layout on the TV monitor screen, for example, when the numeric keypad 9 is pressed, the mouse pointer immediately moves to the lower right corner of the TV screen, and a rough movement is performed, followed by a detailed movement using the cross key. be able to. Also, the movement speed of the mouse pointer can be changed by pressing the cross key while holding down the specially designated key.

  (B) An identification ID corresponding to a mobile phone is given to a transmission signal from the mobile phone remote controller, and at the time of transmission, the timing is adjusted to avoid competition with other mobile phone remote controllers. In the STB or the like, by specifying the sender based on the received identification ID, a pointer cursor corresponding to each sender can be displayed and controlled on the same TV screen. In this case, in particular, by combining with the function (a) above, it is possible to easily suppress the influence of the discontinuity of the pointer movement instruction due to the limitation of the receivable time zone of the remote control signal. Note that a TS allocation number may be assigned to the transmission signal instead of the mobile phone identification ID. That is, the information added to the transmission signal is not limited to the identification ID as long as it is information (identification code) that can identify each mobile phone.

  (C) By limiting the range in which the sender's pointer cursor specified by the identification ID can be moved, a dedicated display area for each identification ID can be created.

  (D) A dedicated storage area for each identification ID is allocated, and the stored video data and the like can be displayed on the dedicated display area by controlling with a pointing device.

  (E) A sender having an identification ID can set a priority, and a remote control signal having a high priority can display a pointer in all areas. In addition, by pressing a specific button, the area at the current point can be displayed on the full screen or switched to the original divided area.

  (F) When video data or the like is transferred to the STB by infrared communication, the identification ID is also transferred and identified on the STB side, whereby the video data or the like can be automatically stored in a storage area corresponding to the identification ID. .

  As described above, according to the embodiment of the present invention, the following effects can be obtained. (A) A pointing device can be displayed by a simple operation of a mobile phone without using a dedicated remote control for the TV monitor, and the operability can be improved by quickly moving or changing the moving speed. (A) A plurality of pointers can be displayed on a TV monitor from a plurality of mobile phones, and the operation can be reflected at the same time, so that a plurality of users can collaborate and communicate. (C) Video data or the like stored in the mobile phone can be transferred to a dedicated area on the STB, and the video data can be displayed by operating a pointer on the dedicated area screen.

  As an application field, for example, in a living room, when a TV becomes a home terminal of an information appliance, it can be used as a family communication tool.

  Note that the embodiments of the present invention are not limited to the above-described ones, and each configuration is further divided in units of processing (steps), or each configuration is integrated, or each data is transmitted via a communication line or the like. It is possible to change the arrangement in a distributed manner as appropriate. Each configuration of the present invention includes hardware and software, and all or a part of the software can be distributed via a computer-readable recording medium or a communication line.

  Further, the bidirectional communication method between the mobile phone and the STB can be realized not only by infrared communication but also by Internet mail, wireless communication using radio waves, cable connection, and the like.
