(First embodiment)
The operation in the remote control system according to the present invention will be described below.

  In the first embodiment of the remote control system according to the present invention, the start of recording a television program on the digital television 2 is controlled by operating the mobile phone 1.

(Operation when receiving a call)
First, the control operation of the digital television 2 by the operation of the mobile phone 1 when the mobile phone 1 receives an incoming call will be described.

  FIG. 3 is a diagram showing how the user 3 controls the digital television 2 by operating the mobile phone 1 when an incoming call is received by the mobile phone 1.

  FIG. 3A shows that the mobile phone 1 received an incoming call while the user 3 was watching a television program on the digital television 2. Here, in FIG. 3 (a), the mobile phone 1 is drawn away from the user 3 to show that the incoming call has arrived. However, the mobile phone 1 is actually within the reach of the user 3's hand. And

  When the user 3 picks up the mobile phone 1 and presses the call button, the user is instructed by wireless communication to start recording a program from the mobile phone 1 to the digital television 2 as depicted in FIG.

  Then, as shown in FIG. 3C, since the recording on the digital television 2 is started and the call on the mobile phone 1 is started, all the broadcasts that the user 3 is making a call on the mobile phone 1 are digital. It will be recorded on the television 2. Therefore, even if the user 3 cannot concentrate on the telephone and see the television screen, the user 3 can cope with the recording without missing the scene during the call.

  In addition, when the mobile phone 1 receives an incoming call, if the digital TV 2 has already recorded another program, the recording cannot be performed. In such a case, a display indicating that recording cannot be performed is displayed on the monitor of the mobile phone 1.

  FIG. 4 is a display example on the monitor of the mobile phone 1 when recording cannot be performed on the digital television 2 when a call is received.

  On the monitor unit 17 of the mobile phone 1, the destination telephone number is displayed as an incoming call display, and a display indicating that the program currently being displayed on the digital television 2 cannot be recorded is displayed. Further, two options “Yes” and “No” are displayed in response to the question of whether or not recording is possible, and the user 3 operates the operation unit of the mobile phone 1 to select one of them. .

  If “Yes” is selected, the telephone call is started without starting the recording because the recording may not be performed. On the other hand, if “No” is selected, since it is not possible to record, it is assumed that watching TV is given priority over calling, and notification that the call is not started and that it is connected to the answering service or cannot be received Will be the other party.

(Operation flowchart when receiving a mobile phone)
FIG. 5 is a flowchart showing the operation of the mobile phone 1 and the digital television 2 constituting the remote control system according to the present invention when a mobile phone arrives in the first embodiment. Hereinafter, unless otherwise specified, each operation is performed by the CPU 11 of the mobile phone 1 or the CPU 21 of the digital television 2.

  First, it is determined whether or not there is an incoming call to the mobile phone 1 (step S101). When the CPU 11 determines that there is no incoming call to the mobile phone 1 (S101: NO), this operation is repeated until there is an incoming call. When it is determined that there is an incoming call (S101: YES), the digital TV 2 is AVRCP (A / V Remote Control Profile) connection is requested (step S102).

  AVRCP is one of the profiles in Bluetooth (registered trademark), and defines a communication procedure for remotely controlling an AV device. By performing communication based on this, a certain degree of compatibility can be maintained between devices that use the same AVCRP.

  If the AVRCP connection is possible in the digital television 2 that has received the AVRCP connection request, the CPU 21 sends a response for allowing the AVRCP connection to the mobile phone 1 via the wireless communication unit 29 (step S201). Thereby, Bluetooth (registered trademark) communication between the mobile phone 1 and the digital television 2 is started.

  In the mobile phone 1 that has received the AVRCP connection response, it is determined whether or not the incoming call button has been pushed by the user 3 (step S103). When it is determined that the incoming call button is not pressed (S103: NO), this operation is repeated, and when it is determined that the incoming call button is pressed (S103: YES), recording is performed on the digital TV 2. A start request command is transmitted (step S104).

  The digital television 2 that has received the recording start request command starts recording the currently displayed program according to the command (step S202), and transmits a response command to the recording start request to the mobile phone 1 (step S203). .

  After receiving a response command to the recording start request and confirming that the recording has started, the mobile phone 1 starts a call (step S105). Thereafter, AVRCP disconnection is requested to the digital television 2 (step S106).

  When the digital TV 2 receives the AVRCP disconnection request, the mobile phone 1 makes a response for accepting the AVRCP disconnection to the mobile phone 1 (step S204), and the mobile phone 1 receiving the response performs the AVRCP disconnection (step S107). The television 2 also performs AVRCP disconnection (step S205).

  Thus, the wireless communication between the mobile phone 1 and the digital television 2 at the start of the call ends, and thereafter, the mobile phone 1 makes a call and the digital television 2 records.

  Note that when the user 3 has already recorded the program that is currently displayed at the time of the incoming call, there is no need to record further, so that the recording is not started but the current location of the program being recorded is not started. You can set chapters.

(Operation at the end of a mobile phone call)
Next, the control operation of the digital television 2 by the operation of the mobile phone 1 at the end of the call in the mobile phone 1 will be described.

  FIG. 6 is a diagram illustrating a state in which the user 3 controls the digital television 2 by operating the mobile phone 1 when the call on the mobile phone 1 is terminated.

  As shown in FIG. 6A, when the call on the mobile phone 1 ends and the user 3 presses the disconnect button on the mobile phone, a notification that the call is ended from the mobile phone 1 to the digital TV 2 This is done by wireless communication.

  Then, the digital television 2 starts reproducing the video from the recording start time (chase reproduction) while continuing to record the program currently being broadcast until the end of the program. As a result, as illustrated in FIG. 6B, the user 3 misses the scene of the TV program broadcast during the call because the digital TV 2 follows the TV program that was being watched before the start of the call. You can continue without it.

  FIG. 7 is a diagram showing the concept of chasing playback in the remote control system according to the present invention.

  It is assumed that a television program being broadcast that is being viewed by the user 3 is composed of scenes 1 to 10. When the television program is viewed on the digital television 2, the scene of the received program is displayed in real time.

  It is assumed that the mobile phone 1 has received an incoming call immediately before the end of the scene 4 of the TV program being broadcast. At this time, when the broadcast TV program is switched from the scene 4 to the scene 5, the recording of the program is started on the digital TV 2 and a call on the mobile phone 1 is started.

  Then, it is assumed that the call on the mobile phone 1 is terminated when the TV program being broadcast switches from the scene 7 to the scene 8. At this time, scene 8 is broadcast in the television program being broadcast, but on digital television 2, since chasing playback is started, scene 5 which is the head portion of the recording start is displayed. At this time, in the digital television 2, the recording of the program is continued, and the scenes 8 and later are sequentially recorded.

  When the broadcast TV program is broadcast up to the scene 10 and the broadcast ends, the recording on the digital TV 2 also ends. At that time, since the playback after the scene 8 still remains, all the recorded programs are played back. Playback continues until it is finished.

  In the description in FIG. 7, the television program is divided into scenes for the sake of simplification, but actually, the timing of the incoming call of the mobile phone or the end of the call is not always coincident with the boundary of the scene of the television program. Of course, recording and playback are started according to the timing of the incoming call of the mobile phone and the end of the call.

(Operation flowchart at the end of a call)
FIG. 8 is a flowchart showing the operation of the mobile phone 1 and the digital television 2 constituting the remote control system according to the present invention at the end of the call in the first embodiment.

  First, it is determined whether or not the end button of the mobile phone 1 has been pressed (step S111). If it is determined that the end button has not been pressed (S111: NO), this operation is repeated until it is pressed. If it is determined that the end button has been pressed (S111: YES), the digital TV 2 is An AVRCP connection is requested (step S112).

  In the digital television 2 that has received the AVRCP connection request, if the AVRCP connection is possible, the mobile phone 1 makes a response for accepting the AVRCP connection (step S211). Thereby, Bluetooth (registered trademark) communication between the mobile phone 1 and the digital television 2 is started.

  In the cellular phone 1 that has received the AVRCP connection response, a chasing playback start request command is transmitted to the digital television 2 (step S113). The digital television 2 that has received the chasing playback start request command starts chasing playback of the currently recorded program according to the command (step S212), and transmits a response command to the chasing playback start request to the mobile phone 1. (Step S213).

  After receiving a response command to the chasing playback start request and confirming that chasing playback has started, the digital TV 2 is requested to disconnect AVRCP (step S114).

  When the digital TV 2 receives the AVRCP disconnection request, the mobile phone 1 makes a response for accepting the AVRCP disconnection to the mobile phone 1 (step S214), and the mobile phone 1 receiving the response performs the AVRCP disconnection (step S115). The television 2 also performs AVRCP disconnection (step S215).

  Thus, the wireless communication between the mobile phone 1 and the digital television 2 at the start of the call ends, and thereafter, the digital television 2 performs chasing playback.

(Second Embodiment)
In the second embodiment of the remote control system according to the present invention, the start of recording of a television program on the digital television 2 is controlled by operating the mobile phone 1.

  Hereinafter, the control operation of the mobile phone 1 by the operation of the digital television 2 when the mobile phone 1 receives an incoming call will be described.

  FIGS. 9 and 10 are diagrams illustrating a state in which the user 3 controls the cellular phone 1 by operating the digital television 1 when the cellular phone 1 receives an incoming call.

  FIG. 9A shows that the mobile phone 1 received an incoming call while the user 3 was watching a television program on the digital television 2. At this time, it is assumed that the user 3 cannot immediately respond to the incoming call depending on whether the jail phone 1 is located away from the user 3 or whether the manner mode is set and the user 3 does not notice the incoming call. Therefore, the mobile phone 1 performs wireless communication with the digital television 2 and notifies the digital television 2 that there is an incoming call.

  Receiving the incoming call notification, the digital television 2 displays on the monitor that the mobile phone 1 has received an incoming call and notifies the user 3 as depicted in FIG. Thereby, the user 3 can recognize that the mobile phone 1 has received an incoming call.

  Then, as illustrated in FIG. 9C, when the user 3 operates the remote controller 4 to send an instruction to start recording to the digital TV, the digital TV 2 is currently displayed as illustrated in FIG. At the same time as recording of the program is started, an instruction by wireless communication is sent to the mobile phone 1 so as to respond to the hold. The hold response is to send a message to the call partner so that the caller waits without disconnecting until the call is answered.

  Then, when the user 3 picks up the mobile phone 1 and pushes the incoming call switch, the telephone line is connected, and the telephone call is started as illustrated in FIG.

  In this case, since the start of program recording and the response hold of the mobile phone 1 can be performed simultaneously by one operation of the remote controller 4, it is possible to perform both operations without rushing, and reliable program recording and incoming response Will be possible, and you will never miss a TV broadcast during a call.

  FIGS. 11A and 11B are display examples when the mobile phone 1 displays an incoming call on the monitor unit 27 of the digital television 2.

  In FIG. 11A, the telephone number of the mobile phone that has received the call and the phone number of the mobile phone that is the destination of the call are displayed on the monitor unit 27. Is displayed. Furthermore, two choices of “hold” and “reject” are displayed.

  When “Hold” is selected, the incoming mobile phone starts a hold response. However, if “Reject” is selected, the incoming call is rejected and it may be connected to the answering machine service or receive an incoming call. The other party will be notified that it cannot.

  FIG. 11B is almost the same as FIG. 11A, except that the mobile phone that received the call is identified by a personal name instead of a telephone number. By previously registering the mobile phone number and the owner's name in the digital TV 2, a display as shown in FIG. 10B is possible.

  FIG. 11C is an example of registration of the telephone number and owner name of the mobile phone for the digital television 2.

(Operation flowchart when receiving a mobile phone)
FIG. 12 is a flowchart showing the operation when the mobile phone 1 and the digital television 2 constituting the remote control system according to the present invention receive a mobile phone in the second embodiment.

  First, it is determined whether or not there is an incoming call to the mobile phone 1 (step S121). If it is determined that the mobile phone 1 has not received an incoming call (S121: NO), this operation is repeated until an incoming call is received. If it is determined that an incoming call has been received (S121: YES), the AVRCP is sent to the digital TV 2. A connection is requested (step S122).

  In the digital television 2 that has received the AVRCP connection request, if the AVRCP connection is possible, the mobile phone 1 makes a response for accepting the AVRCP connection (step S221). Thereby, Bluetooth (registered trademark) communication between the mobile phone 1 and the digital television 2 is started.

  Next, the mobile phone 1 that has received the AVRCP connection response notifies the digital TV 2 of incoming information in the mobile phone 1 (step S123). Receiving the notification of the incoming information, the digital television 2 displays the incoming information on the monitor as shown in FIG. 10 (step S222), and further responds to the notification of the incoming information to the mobile phone 1 (step S223). ).

  Next, in the digital television 2, it is determined whether or not the user 3 has selected the response hold (step S224). When it is determined that the response hold is not selected (S224: NO), this process is repeated, and when it is determined that the response hold is selected (S224: YES), the response hold is applied to the mobile phone 1. The selection is notified (step S225).

  The cellular phone 1 that has received the notification puts a response on hold with respect to the called party (step S124), and makes a response to the response hold notification of the digital television 2 (step S125). Upon receiving the response, the digital television 2 starts recording the currently displayed television program (step S226).

  Next, in the mobile phone 1, it is determined whether or not the incoming call button has been pushed by the user 3 (step S126). If it is determined that the incoming call button is not pressed (S126: NO), this operation is repeated, and if it is determined that the incoming call button is pressed (S126: YES), a call is started (step S127). ). Thereafter, AVRCP disconnection is requested to the digital television 2 (step S128).

  When the digital TV 2 receives the AVRCP disconnection request, the digital TV 2 makes a response to the mobile phone 1 to acknowledge AVRCP disconnection (step S227), and the mobile phone 1 that has received the response performs AVRCP disconnection (step S129). The television 2 also performs AVRCP disconnection (step S228).

  Thus, the wireless communication between the mobile phone 1 and the digital television 2 at the start of the call ends, and thereafter, the mobile phone 1 makes a call and the digital television 2 records.

  Even in the present embodiment, when the user 3 has already recorded the program that is currently displayed at the time of the incoming call, there is no need to record further, so recording is not started but recording is started. The chapter can be set at the current location of the program.
