Embodiment 1
(System overview)
Based on FIG. 2, the outline | summary of the content output system 100 which concerns on this embodiment is demonstrated. FIG. 2 is a diagram showing an outline of the content output system 100. As illustrated, the content output system 100 includes an STB (Set Top Box) 1 and a TV (television receiver) 3. In the content output system 100, the STB 1 and the TV 3 are connected by an HDMI (High Definition Multimedia Interface, registered trademark) cable, and the STB 1 transmits the content (hereinafter referred to as external content) to the TV 3 for output. Can do. The TV 3 can receive and output broadcast content.

  As described above, the STB 1 is a source device that causes the TV 3 to transmit and output external content. The STB 1 only needs to output content different from the TV 3, and may be, for example, a game machine, a recorder, or a device that outputs content on the Internet. The content on the Internet may be, for example, moving image content, a game, or the like, or application software that can be executed by the STB 1. In general, such content often takes a long time from when the output device is activated until it can be output. However, the STB 1 of the present embodiment can quickly output even such content by shifting to a quick standby state described later.

  Since the TV 3 includes a tuner and has a function of receiving broadcast content, the STB 1 does not need to include a tuner. However, a configuration for acquiring content different from the TV 3 may be provided, such as a tuner that receives broadcast content different from the TV 3 (for example, satellite broadcast content). The STB 1 can also control the operation by transmitting a control signal called a CEC (Consumer Electronics Control) command to the HDMI-connected TV 3.

  The TV 3 is a display device that outputs broadcast content, and also outputs external content transmitted from the STB 1 as described above. Note that the TV 3 basically selects broadcast content, external content, and other content different from these (for example, internal content recorded inside the TV 3), that is, any one of the above contents. Output one. However, the TV 3 may have a function of dividing a display screen and simultaneously outputting a plurality of contents from the above contents. Similarly to the STB 1, the TV 3 can transmit a control signal to the HDMI connected STB 1 to control its operation.

  Next, an operation example of the content output system 100 will be described. First, in (a) of the figure, both STB1 and TV3 are in a dormant state. Here, the hibernation state is a state in which power is supplied from the power source, but almost all the processing units are not activated except for some components such as a processing unit that receives a user operation. In the hibernation state, a processing unit with relatively large power consumption such as a control unit is not activated, so that the power consumption in the hibernation state is the lowest among all the operation modes.

  Here, when the user approaches STB1, both STB1 and TV3 shift to the quick standby state, as shown in FIG. Specifically, when the human sensor provided in the STB 1 reacts to the user, the STB 1 shifts to the quick standby state and transmits an instruction to shift to the quick standby state to the TV 3, and thus the TV 3 also shifts to the quick standby state. To do. Here, the quick standby state of the TV 3 is a state where each processing unit except the display unit is activated, and the quick standby state of the STB 1 is a state where each processing unit excluding an indicator indicating the operation state of the STB 1 with a lighting state is activated. State. The quick standby state is a startup preparation state in which all the processing units are started up, although the power consumption is larger than that in the hibernation state. For this reason, after the transition to the quick standby state is completed, it is possible to output the content promptly. Then, when both devices shift to the quick standby state, a handshake is performed between the STB 1 and the TV 3 to establish an HDMI connection, whereby external content can be transmitted and received between the STB 1 and the TV 3.

  As shown in FIG. 5C, when the user desires to view the content (external content) of the STB 1, the user operates the STB remote controller 2 to perform an activation operation on the STB 1. The STB 1 shifts to the startup state in accordance with this startup operation and transmits a startup instruction to the TV 3, whereby the TV 3 also shifts to the startup state. Since the transition to the activated state is the transition from the quick standby state, the transition is completed in a short time, and the information received from the STB 1, that is, the external content is instantaneously displayed on the TV 3. The activation state of the TV 3 is a state in which each processing unit necessary for outputting content is activated, and the activation state of the STB 1 is a state in which the above-described indicators are lit and each processing unit is activated.

  On the other hand, as shown in (d) of the figure, when the user desires to view the content (broadcast content) of the TV 3, the user operates the TV remote controller 4 to start the TV 3. This activation operation is also detected in the STB 1, and the STB 1 shifts to an activation state in response to this detection, and outputs the broadcast content of the channel (hereinafter referred to as the last channel) output by the TV 3 to the TV 3. To instruct. In this case as well, as in the case of (c) above, the TV 3 shifts from the quick standby state to the start-up state, so that the time required for this shift is short, and the broadcast content of the last channel is instantaneously displayed on the TV 3. The

  Further, as shown in (e) of the figure, when the user does not intend to start both STB1 and TV3 and moves outside the detection range of the human sensor of STB1, STB1 enters a sleep state with respect to TV3. The STB 1 also shifts to the dormant state. Thereby, both STB1 and TV3 shift to a dormant state.

  As described above, in the content output system 100, both the STB 1 and the TV 3 shift to the quick standby state when a user is detected. When the user gives an activation instruction to the STB 1, the external content is output to the TV 3, and when the user gives an activation instruction to the TV 3, the broadcast content is output to the TV 3. Accordingly, it is possible to promptly output content according to the user's intention.

(Main components of each device)
Next, the main configuration of the STB 1 and the TV 3 will be described with reference to FIG. FIG. 1 is a block diagram showing an example of a main configuration of the STB 1 and the TV 3. The figure also shows an STB remote controller 2 that is a remote operation device for remotely operating the STB 1, a TV remote controller 4 that is a remote operation device for remotely operating the TV 3, and a linkage device 5 that is a source device other than the STB 1. Yes. Since STB1 and TV3 are often arranged at a short distance, a signal transmitted by STB remote controller 2 can be received by both STB1 and TV3 as shown in the figure. Similarly, a signal transmitted by the TV remote controller 4 can be received by both the STB 1 and the TV 3.

  The cooperating device 5 is HDMI-connected to the TV 3 in the same manner as the STB 1, and transmits external content different from the STB 1 to the TV 3 for output. The cooperation device 5 may be any device that outputs content different from that of the STB 1, and may be, for example, a game machine, a recorder, or a device that acquires and outputs content on the Internet.

(STB configuration)
The STB 1 includes an STB remote control signal receiving unit 11, an STB side HDMI communication unit 12, a human sensor 13, a communication unit 14, an STB storage unit 15, and an STB control unit 20. The STB control unit 20 includes a monitoring unit (detection unit) 21, an STB side command detection unit (target determination unit) 22, an STB side state control unit (state control unit) 23, and an external device control unit (transition instruction unit) 24. STB side connection control unit 25 and content processing unit 26 are included.

  The STB remote control signal receiving unit 11 receives a signal transmitted from the remote control. The STB side HDMI communication unit 12 transmits / receives contents and control signals to / from HDMI-connected devices (TV 3, cooperation device 5, etc.). The human sensor 13 is a sensor that detects a user near the STB 1. The communication unit 14 acquires content from outside the STB 1 through a communication network such as the Internet. If the STB 1 is configured to output content stored in the STB storage unit 15, the communication unit 14 may be omitted. The STB storage unit 15 stores various data handled by the STB 1. The STB1 control unit 20 controls each part of the STB1 in an integrated manner.

  The monitoring unit 21 detects the presence of the user. Specifically, the monitoring unit 21 monitors whether there is a user near the STB 1 based on the detection result of the human sensor 13 and detects the presence of the user. When the monitoring unit 21 detects the user, both the STB 1 and the TV 3 shift to the quick standby state.

  The STB side command detection unit 22 detects a command from the signal received by the STB remote control signal reception unit 11 from the remote control. In addition, the STB side command detection unit 22 determines which device the detected command is for. Specifically, the STB side command detection unit 22 determines that the command detected from the signal whose transmission source is the STB remote controller 2 is a command for the STB 1. On the other hand, the command detected from the signal whose source is the TV remote controller 4 is determined to be a command for the TV 3.

  The STB side state control unit 23 controls the transition of the operation state of the STB 1. Note that there are three operating states of the STB 1 to be controlled by the STB-side state control unit 23: the above-described hibernation state, quick standby state, and activation state.

  The external device control unit 24 controls the operation of a device (such as the TV 3 or the link device 5) that is HDMI-connected to the STB 1. Details of the operation control by the external device control unit 24 will be described later.

  The STB side connection control unit 25 performs processing for establishing an HDMI connection between the STB 1 and an external device (TV3 or the like). More specifically, the STB side connection control unit 25 transmits and receives predetermined information to and from the TV side connection control unit 43 of the TV 3 to perform handshaking, so that the STB 1 can transmit external content to the TV 3. .

  The content processing unit 26 transmits external content to the TV 3 via the STB side HDMI communication unit 12. Although details will be described later, the content processing unit 26 starts transmission of external content to the TV 3 in the quick standby state.

(TV configuration)
The TV 3 includes a TV remote control signal receiving unit 31, a TV-side HDMI communication unit 32, a display unit 33, a TV storage unit 34, a tuner 35, and a TV control unit 40. The TV control unit 40 includes a TV-side command detection unit 41, a TV-side state control unit 42, a TV-side connection control unit 43, an output control unit 44, a content acquisition unit 45, and a broadcast reception control unit 46.

  The TV remote control signal receiving unit 31 receives a signal transmitted from the remote control. The TV-side HDMI communication unit 32 is for transmitting / receiving content and control signals to / from HDMI-connected devices (such as the STB 1 and the link device 5). The display unit 33 displays an image. For example, images such as broadcast content, external content, and various setting screens are displayed on the display unit 33. The TV storage unit 34 stores various data handled by the TV 3. The tuner 35 selects and receives a broadcast signal of a required channel from broadcast signals received by an antenna (not shown), and outputs it as broadcast content. The tuner 35 may be externally attached to the TV 3. The TV control unit 40 controls each part of the TV 3 in an integrated manner.

  The TV-side command detection unit 41 detects a command from the signal received by the TV remote control signal reception unit 31 from the remote control. Similarly to the STB side command detection unit 22, the TV side command detection unit 41 determines which device the command is intended for, and if the command is for the TV 3, the detected command is determined. The command is transmitted to the corresponding processing unit.

  The TV side state control unit 42 controls the transition of the operation state of the TV 3. Note that there are three operating states of the TV 3 to be controlled by the TV-side state control unit 42: the above-described sleep state, quick standby state, and startup state.

  The TV-side connection control unit 43 performs processing for establishing an HDMI connection between the TV 3 and an external device (STB 1, linkage device 5, etc.). More specifically, the TV-side connection control unit 43 transmits and receives predetermined information to and from the STB-side connection control unit 25 of the STB 1 and performs handshaking, whereby the TV 3 becomes ready to receive external content from the STB 1.

  The output control unit 44 performs control related to input switching of the TV 3. Specifically, the output control unit 44 switches whether to output broadcast content output from the tuner 35 or to output external content received from the STB 1 that is an external input.

  The content acquisition unit 45 acquires external content. Specifically, the content acquisition unit 45 acquires external content from the STB 1 or the cooperation device 5 via the TV-side HDMI communication unit 32 and outputs the external content to the output control unit 44.

  The broadcast reception control unit 46 controls reception of broadcasts by the tuner 35. Specifically, the broadcast reception control unit 46 selects a channel received by the tuner 35, and transmits the broadcast content output by the tuner 35 to the output control unit 44 in response to this selection.

(Prerequisite processing flow)
Next, the processing of the STB 1 that is the premise of each embodiment of the present invention will be described with reference to FIG. FIG. 3 is a flowchart illustrating a process example that is a premise of the process of each embodiment among the processes executed by the STB 1. Although not shown in the drawings, the processing executed by the TV 3 will also be described below.

  When both the STB 1 and the TV 3 are in a dormant state (S1), the monitoring unit 21 waits for human detection by the human sensor 13 (S2, detection step). When the monitoring unit 21 determines that a person is detected from the output of the human sensor 13 (YES in S2), the STB side state control unit 23 shifts the operation state of the STB 1 to the quick standby state (S3, state control). Step).

  In addition, the external device control unit 24 transmits an instruction to shift to the quick standby state to the TV 3 via the STB side HDMI communication unit 12 (S4, shift instruction step). And in TV3 which received this instruction | indication, the TV side state control part 42 transfers TV3 to a quick standby state (state control step).

  When both the STB 1 and the TV 3 enter the quick standby state, the STB side connection control unit 25 establishes an HDMI connection between the STB 1 and the TV 3 (S5). Note that, in the quick standby state, the external device control unit 24 preferably switches the output setting of the TV 3 to one corresponding to the external content. The output setting to be switched is not particularly limited. For example, input settings (whether external content or broadcast content is output), output volume, screen size (full screen, underscan, etc.), image quality settings (AV position), etc. Etc.

  After S5, the STB side command detection unit 22 determines whether an activation instruction is received from the STB remote controller 2 (S6). If it is determined that the activation instruction from the STB remote controller 2 has been received (YES in S6), the STB side state control unit 23 and the external device control unit 24 shift the STB 1 and the TV 3 to the activation state, respectively (S7). Specifically, the STB side state control unit 23 shifts the STB 1 to the activated state. Further, the external device control unit 24 transmits an activation instruction to the TV 3, and the TV-side state control unit 42 of the TV 3 shifts the TV 3 to the activation state in accordance with this instruction.

  On the other hand, when the STB side command detection unit 22 determines that the activation instruction has not been received (NO in S6), the transition to the activation state is not performed, and the process proceeds to S8. In S8, the monitoring unit 21 determines whether or not a person is detected from the output of the human sensor 13 (S8).

  If it is determined in S8 that the monitoring unit 21 has detected a person (YES in S8), the process returns to S6. On the other hand, when the monitoring unit 21 does not detect a person (NO in S8), the STB side state control unit 23 shifts the operation state of the STB 1 to a dormant state (S9). Further, the external device control unit 24 transmits an instruction to shift to the hibernation state to the TV 3 (S10). As a result, the TV-side state control unit 42 causes the TV 3 to shift to the dormant state, and both the STB 1 and the TV 3 return to the dormant state (S1). When the output setting of the TV 3 has been switched to one corresponding to the external content, when returning the TV 3 to the hibernation state, the external device control unit 24 instructs to return to the output setting before the switching. .

  As described above, when the user is no longer detected by the human sensor 13, both the STB 1 and the TV 3 return to the hibernation state. Therefore, the period of the quick standby state is limited to the period during which the user is detected. Therefore, it is possible to minimize the period during which the quick standby state in which power consumption is increased as compared with the hibernation state is necessary. When the user gives an activation instruction, the STB 1 and the TV 3 in the quick standby state can be shifted to the activated state, and external contents can be output quickly. Also, by setting the input setting of the TV 3 as broadcast content, it is possible to output broadcast content (for example, last channel broadcast content) at the time of activation.

(Process flow)
The flow of processing (source device control method) executed by the STB 1 in this embodiment will be described with reference to FIG. FIG. 4 is a flowchart illustrating an example of processing executed by the STB 1. Note that the same processes as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted as appropriate. Although not shown in the drawings, the processing (display device control method) executed by the TV 3 will also be described below.

  After S5, the external device control unit 24 instructs the TV 3 to start receiving the last channel. Further, the content processing unit 26 starts transmission of external content to the TV 3. In the TV 3, the content acquisition unit 45 starts receiving external content, and the broadcast reception control unit 46 starts receiving broadcast content of the last channel. However, since an activation instruction is not transmitted to the TV 3 at this time, the output control unit 44 stands by without outputting any external content or broadcast content. With these processes, in the TV 3, both the last channel and the HDMI input, that is, the external content are received (S21), and the process proceeds to S6.

  In S6, the STB side command detection unit 22 determines whether or not an activation instruction has been received. If it is determined that the activation instruction has been received (YES in S6), the STB side command detection unit 22 further determines whether or not the activation instruction is transmitted from the STB remote controller 2 (S22, object determination step) ). When the TV remote controller 4 issues a start-up instruction, in the TV 3 that has received the instruction, the TV-side state control unit 42 maintains the quick standby state without shifting the TV 3 to the start-up state. Wait for the activation instruction.

  When the STB side command detection unit 22 determines that the source of the activation instruction is the STB remote controller 2 (YES in S22), the external device control unit 24 inputs the input via the STB side HDMI communication unit 12 to the HDMI input An instruction is transmitted to the TV 3 to switch to (S23). Then, in the TV 3 that has received this instruction, the output control unit 44 performs input switching so that external content is output (output control step). Thereby, the display of the external content is started on the display unit 33 of the TV 3 by shifting the TV 3 to the activated state in S7 (external device control step).

  On the other hand, when the STB-side command detection unit 22 determines that the activation instruction is not transmitted from the STB remote control 2, that is, the TV remote control 4 (NO in S22), the external device control unit 24 sets the input to the last channel. An instruction is transmitted to the TV 3 to switch (S24). Then, in the TV 3 that has received this instruction, the output control unit 44 performs input switching so that broadcast content is output. Thereby, the display of the last channel broadcast content is started on the display unit 33 of the TV 3 by shifting the TV 3 to the activated state in S7 (external device control step).

  With the above processing, as in the example of FIG. 2, when the user gives an activation instruction with the STB remote controller 2, the external content is instantaneously output to the TV 3, and when the activation instruction is given with the TV 3, the broadcast is performed. Content (last channel) can be output instantaneously.

  In the above-described processing, when the activation instruction is given by the TV remote controller 4, in the TV 3 that has received the instruction, the TV-side state control unit 42 may shift the TV 3 to the activation state. In this case, the output control unit 44 of the TV 3 starts output of broadcast content or external content, and then performs output switching as necessary in accordance with the instruction from the STB 1 in S23 or S24.

(Input switching judgment on the TV side)
In the above description, an example is described in which the input switching of the TV 3 is performed according to the determination result from which remote controller the STB 1 is an activation instruction, but the determination for the input switching may be performed by the TV 3.

  For example, when receiving an activation instruction, the output control unit 44 of the TV 3 may perform input switching depending on whether the activation instruction is received without passing through the STB 1. Specifically, when the output control unit 44 determines in the quick standby state that an activation instruction has been received without going through the STB 1 (for example, when an activation instruction has been received from the TV remote controller 4), the output target is also set as broadcast content. Good. This is because if the activation instruction is accepted without going through the STB 1, there is a high possibility that the user does not intend to output external content.

  On the other hand, when it is determined that the activation instruction is received via the STB 1 (for example, when the activation instruction is received from the external device control unit 24 of the STB 1 that has received the activation instruction from the STB remote controller 2), the output target is also set as the external content. Good. This is because when the activation instruction is received from the STB 1, it is highly likely that the user intends to output external content.

(About content output immediately after startup)
In the above, the example in which the content according to whether or not the transmission source of the activation instruction is the STB remote controller 2 is output has been described, but the criterion for determining which content is output is not limited to this example.

  For example, it may be determined which content is output according to the user's preset settings. In this case, for example, a screen as shown in FIG. 5 may be displayed on the TV 3 to allow the user to set which content is to be output. FIG. 5 is a diagram illustrating an example of an input setting setting screen immediately after the TV 3 is started from the quick standby state that has been shifted to the detection by the human sensor 13 as a trigger. In the example shown in the drawing, “external device input (HDMI)” and “normal (last channel)” are displayed as choices of “input setting immediately after startup by an external device sensor”. Such a setting screen may be displayed on the TV 3 or may be displayed on the TV 3 by the STB 1.

  When “external device input (HDMI)” is selected on this setting screen, the output control unit 44 of the TV 3 stores a setting for outputting external content at the time of activation. When receiving the activation instruction, the output control unit 44 starts the output of the external content received from the STB 1 regardless of the source of the activation instruction.

  When “normal (last channel)” is selected on the setting screen, the output control unit 44 of the TV 3 stores a setting for outputting broadcast content of the last channel at the time of activation. Then, when receiving the activation instruction, the output control unit 44 starts to output the broadcast content of the last channel regardless of the origin of the activation instruction.

  In each of the above cases, when the activation instruction is received by the STB 1, the external device control unit 24 of the STB 1 transmits the activation instruction to the TV 3, and the TV-side state control unit 42 triggers the TV 3 to receive the instruction. Set to the activated state.

  On the other hand, in each case described above, when the TV 3 receives an activation instruction, the TV-side state control unit 42 activates the TV 3 with the reception of this instruction. In this case, the TV-side state control unit 42 of the TV 3 may notify the STB 1 that the TV 3 is shifted to the activated state. In particular, when the output of broadcast content is started, the STB 1 is also notified of that fact, and the STB side state control unit 23 may cause the STB 1 to transition to a dormant state upon receipt of this notification. Thereby, the power consumption of STB1 at the time of viewing broadcast content can be reduced.

[Embodiment 2]
A second embodiment of the present invention will be described with reference to FIG. The STB 1 of this embodiment is different from the STB 1 of the above embodiment in that the external device control unit 24 shifts not only the TV 3 but also the operating state of the cooperation device 5. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

(Process flow)
The flow of processing executed by the STB 1 in this embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating an example of processing executed by the STB 1. Note that the same processes as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  When the STB 1, the TV 3, and the cooperation device 5 are all in a dormant state (S31), the monitoring unit 21 waits for detection of a person by a human sensor (S2). If the monitoring unit 21 determines that a person has been detected from the output of the human sensor 13 (YES in S2), the process proceeds to S3 as in FIG. After S3, the external device control unit 24 transmits an instruction to shift to the quick standby state to the TV 3 and the cooperation device 5 (S32). Then, the TV 3 that has received this instruction shifts to the quick standby state as described in the above embodiment, and similarly, the linked device 5 also shifts to the quick standby state.

  If it is determined that the STB 1 has received an activation instruction after shifting to the quick standby state (YES in S6), the STB side state control unit 23 and the external device control unit 24 activate the STB 1, the TV 3, and the cooperation device 5, respectively. The state is shifted (S33). Specifically, the STB side state control unit 23 shifts the STB 1 to the activated state. Further, the external device control unit 24 transmits a start instruction to the TV 3 and the link device 5, and the TV 3 shifts to the start state as described in the above embodiment, and the link device 5 similarly shifts to the start state. .

  On the other hand, when the activation instruction is not received (NO in S6) and no person is detected (NO in S8), STB1 shifts to a dormant state (S9). Then, the external device control unit 24 transmits an instruction to shift to the sleep state to the TV 3 and the link device 5 to the TV 3 and the link device 5 (S34). As a result, the TV 3 shifts to the dormant state as described in the above embodiment, and the linked device 5 similarly shifts to the dormant state. That is, all of STB1, TV3, and cooperation apparatus 5 return to a dormant state (S1).

  According to the above processing, when the human sensor detects a person, the STB 1, the TV 3, and the cooperation device 5 are shifted to the quick standby state. When the user gives an activation instruction using the remote controller, the STB 1, the TV 3, and the cooperation device 5 are shifted to the activated state. Therefore, any content of the STB 1, the TV 3, and the cooperation device 5 can be promptly output to the TV 3 after receiving the activation instruction.

(About quick standby settings for each linked device)
In the above description, an example has been described in which the operating state is shifted in conjunction with the STB 1 for all the linked devices 5 that are communicably connected to the TV 3, but the operating state may be shifted only for the predetermined linked device 5. For example, the user may be able to set in advance the cooperation device 5 that shifts the operation state. This will be described with reference to FIG.

  FIG. 7 is a diagram illustrating an example of a setting screen for setting the cooperation device 5 that shifts the operation state in conjunction with the shift of the STB 1 to the quick standby state. In the illustrated example, as the “HDMI cooperation device quick standby setting”, three cooperation devices 5 connected to the TV 3 (device names are “TV LC-XXXX”, “BD PLAYER”, and “SHXX”, respectively) are displayed. Has been. “TV LC-XXXX” is TV3, “BD PLAYER” is a Blu-ray Disc player, and “SHXX” is a game machine. In this way, it may be possible to set whether or not to shift the TV 3 to the quick standby state. Such device names can be detected from each other as long as they are devices connected by HDMI CEC. Further, such a setting screen may be displayed on the TV 3, or may be displayed on the TV 3 by the STB 1 or the cooperation device 5. On this setting screen, each linked device 5 can be set to “set” or “not set” so as to shift the operation state in conjunction with the shift of the STB 1 to the quick standby state.

  The external device control unit 24 of the STB 1 stores this setting. When the STB 1 shifts to the quick standby state, the TV 3 is shifted to the quick standby state, and the linked device 5 that is set to shift the operation state in conjunction with the STB 1 is also shifted to the quick standby state. Thereby, only the user's desired cooperation device 5 can be shifted to the quick standby state.

  Note that the STB 1 may determine which linked device 5 is to be shifted to the quick standby state. For example, the relatively frequently used linked device 5 may be shifted to the quick standby state, and the relatively less frequently used linked device 5 may not be shifted.

[Embodiment 3]
A third embodiment of the present invention will be described with reference to FIG. The STB 1 and the TV 3 of the present embodiment are described above in terms of automatically shifting to the startup state when a predetermined condition (hereinafter referred to as an immediate startup condition) is satisfied in the state of shifting to the quick standby state. It is different from STB1 and TV3 of each embodiment. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

  The immediate activation condition may be set such that it can be said that the user is highly likely to start viewing the content when the condition is satisfied. For example, the current time is included in a predetermined time zone, the predetermined program is being broadcast or broadcast within a predetermined time from the current time, and there is a broadcast program reserved for viewing within the predetermined time from the current time At least one of these may be used as an immediate activation condition. In addition, the predetermined time zone may be a time zone in which content is generally likely to be viewed on the TV 3 (for example, a time zone called a golden time). In addition to this, for example, a usage history of the TV 3 or the STB 1 may be recorded, and a time zone of high content viewing frequency derived from the history may be used. The predetermined program may be set in advance by the user, or may be automatically set by the STB 1 based on the preference information such as the user's favorite genre, viewing history, or the like.

  Moreover, it is good also considering immediate acquisition conditions that TV3 or STB1 has acquired the content and information which want to show with respect to a user. For example, the immediate start condition may be that emergency information such as an earthquake or a typhoon is included in the broadcast content that has started to be received after shifting to the standby state. Alternatively, for example, the STB 1 may have received the notification that the STB 1 has completed the download of the external content or that the distribution of the new content that matches the user's preference has started.

(Process flow)
The flow of processing executed by the STB 1 in this embodiment will be described with reference to FIG. FIG. 8 is a flowchart illustrating an example of processing executed by the STB 1. Note that the same processes as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  The STB side state control unit 23 that has shifted the STB 1 to the quick standby state in S3 determines whether or not the immediate activation condition is satisfied (S41, condition determination step). That is, in this embodiment, the STB side state control unit 23 functions as a condition determination unit that determines whether or not the immediate activation condition is satisfied. A condition determination unit may be provided separately from the STB side state control unit 23. Here, when it is determined that the immediate activation condition is not satisfied (NO in S41), the processing from S6 onward is performed as in the above embodiments.

  On the other hand, when it is determined that the immediate activation condition is satisfied (YES in S41), the STB side state control unit 23 sets STB1 in the activated state. In addition, the external device control unit 24 transmits a start instruction to the TV 3 to put the TV 3 into a start state (S7, external device control step). Thus, when the immediate activation condition is satisfied, the user can start viewing the content without performing any operation by simply entering the detection range of the human sensor 13.

  Note that whether the broadcast content or the external content is output from the TV 3 activated in S7 may be determined in advance as described with reference to FIG. Further, the STB 1 or the TV 3 may determine which is output. For example, if the satisfied immediate activation condition is related to the TV 3 or the broadcast content, the broadcast content may be output. If the satisfied immediate activation condition is related to STB 1 or external content, the external content may be output. Furthermore, when outputting broadcast content, the broadcast content of the last channel may be output, or the broadcast content corresponding to the satisfied immediate activation condition may be output. In the latter case, for example, broadcast content of a broadcast program channel reserved for viewing may be output.

(About automatic startup settings)
It is preferable that the user can set whether or not to perform the automatic activation. In this setting, for example, a setting screen as shown in FIG. 9 may be displayed. FIG. 9 is a diagram illustrating an example of a setting screen for setting whether to allow automatic activation. In the illustrated example, three options “always activated”, “auto”, and “not always activated” are displayed. Such a setting screen may be displayed on the TV 3 or may be displayed on the TV 3 by the STB 1.

  The STB side state control unit 23 stores this setting. Then, after the STB 1 is shifted to the quick standby state, processing corresponding to the stored setting is performed. That is, if the setting is “always activated”, the STB 1 is shifted to the activated state regardless of whether or not the immediate activation condition is satisfied, and the TV 3 is shifted to the activated state by the external device control unit 24. On the other hand, if the setting is “not always activated”, the quick standby state of the STB 1 is maintained and the transition instruction is not transmitted to the TV 3 regardless of whether or not the immediate activation condition is satisfied. If the setting is “auto”, the STB side state control unit 23 shifts the STB 1 to the start state and satisfies the external device control unit when the immediate start condition is satisfied by the process described with reference to FIG. 24, the TV 3 is shifted to the activated state.

[Modification]
In each of the above-described embodiments, when broadcasting content is output, the STB 1 may shift from the activated state to the quick standby state or the hibernate state. In this case, the STB 1 may maintain the quick standby state without shifting to the activated state, or may shift from the quick standby state to the hibernate state. For example, in the example of FIG. 4, when the input of the TV 3 is switched to the last channel in S24, the external content of the STB 1 is not output. Therefore, in the subsequent S7, after the external device control unit 24 of the STB 1 shifts the TV 3 to the start-up state, the STB side state control unit 23 maintains the STB 1 in the quick standby state or changes from the quick standby state to the hibernation state. It may be migrated. The TV 3 may perform the same control. In this case, the TV 3 whose input is switched to the last channel transmits an instruction to shift to the quick standby state or the hibernation state to the STB 1. According to the configuration of the present modification, the power consumption of the STB 1 can be reduced while viewing broadcast content.

  Note that when STB 1 is shifted to the sleep state, the power consumption of STB 1 is reduced, but when the user performs an operation of switching the output content to the external content, the time until the external content is output is long. turn into. For this reason, it is preferable that the user can select whether or not to return the STB 1 to the hibernation state. For example, whether the STB1 is returned to the dormant state when the broadcast content is viewed in accordance with the setting contents in advance through a setting screen for setting whether to return the STB1 to the dormant state or the like. You may decide whether or not.

  Further, in each of the above embodiments, an example in which a user is detected by a human sensor has been shown, but the configuration for detecting a user is not limited to this, and the surroundings of at least one of STB1 and TV3 (display screen of TV3) As long as it is capable of detecting a user within a range in which the user can enter the field of view. For example, the user may be detected by photographing the periphery of the STB 1 with a camera and analyzing the video, or the proximity of the user may be detected using a proximity sensor.

  Further, in each of the above embodiments, an example in which the human sensor is provided in the STB 1 is shown. However, the human sensor (or an alternative configuration as described above) is provided in any device included in the content output system 100. Just do it. For example, the TV 3 may be provided, or another device such as the cooperation device 5 may be provided.

  Further, in each of the above embodiments, an example in which each device is connected by HDMI has been described. However, the above-described connection of each device is performed in a manner capable of transmitting content and control signals as described above. What is necessary is not limited to HDMI connection. For example, each device may be connected by wired communication other than HDMI, each device may be connected by wireless communication, contents are transmitted by wired communication, and control signals are transmitted by wireless communication. Wired communication and wireless communication may be used in combination, such as transmission.

[Example of software implementation]
The control blocks of STB 1 and TV 3 (particularly STB control unit 20 and TV control unit 40) may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or a CPU (Central Processing Unit). ) May be implemented by software.

  In the latter case, the STB 1 and the TV 3 include a CPU that executes instructions of a program that is software that realizes each function, a ROM (Read Only Memory) in which the program and various data are recorded so as to be readable by a computer (or CPU), or A storage device (these are referred to as “recording media”), a RAM (Random Access Memory) that expands the program, and the like are provided. And the objective of this invention is achieved when a computer (or CPU) reads the said program from the said recording medium and runs it. As the recording medium, a “non-temporary tangible medium” such as a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. The program may be supplied to the computer via an arbitrary transmission medium (such as a communication network or a broadcast wave) that can transmit the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave in which the program is embodied by electronic transmission.

[Summary]
The source device (STB1) according to the first aspect of the present invention is a source device (STB1) that is connected to the display device (TV3) and transmits the content to the display device (TV3) and outputs the content. When the detection unit (monitoring unit 21) to detect and the detection unit (monitoring unit 21) detect the presence of a user, the display device (TV3) is shifted from a sleep state to a startup preparation state (quick standby state). When the transition instruction unit (external device control unit 24) and the detection unit (monitoring unit 21) detect the presence of a user, the state control unit (STB1) shifts the source device (STB1) from the hibernation state to the startup preparation state ( When the STB side state control unit 23), the display device (TV3), and the source device (STB1) receive a start instruction in a state in which they have shifted to the start preparation state, the start instruction When it is determined that the target determination unit (STB-side command detection unit 22) for determining the target and the target of the activation instruction is the display device (TV3), broadcast content is output to the display device (TV3). And an external device control unit (24) that starts output of the content when it is determined that the target of the activation instruction is the source device (STB1).

  According to the above configuration, when a start instruction is received in a state where the display device and the source device have shifted to the start preparation state, it is determined whether the target of the start instruction is the display device or the source device To do. When the activation instruction target is determined to be the display apparatus, the display apparatus starts outputting broadcast content. When the activation instruction target is determined to be the source apparatus, the source apparatus transmits. Start outputting content.

  Therefore, according to said structure, the content along a user's will can be output. This is because a user who has given a start instruction for a source device is likely to intend to output content supplied by the source device. Similarly, a user who has given a start instruction for a display device may be broadcast content. This is because there is a high possibility that there is an intention to output.

  In addition, according to the above configuration, both the display device and the source device are shifted from the hibernation state to the start preparation state in response to the user detection. The content can be output in a shorter time compared to the case of starting from the start. That is, according to said structure, there exists an effect that the content along a user's will can be output rapidly.

  According to the above configuration, in the startup preparation state, transmission of content to the display device is started, and acquisition of broadcast content is started on the display device. Therefore, when an activation instruction is given, it is possible to immediately output either broadcast content or content.

  The source device according to aspect 3 of the present invention is the source apparatus according to aspect 1 or 2, wherein the target determination unit is configured to perform the activation instruction if the transmission source of the activation instruction is the remote operation device (STB remote controller 2) of the source apparatus. If the target of the activation instruction is a source device and the transmission source of the activation instruction is a remote operation device (TV remote controller 4) of the display device, it may be determined that the object of the activation instruction is a display device. .

  According to the above configuration, if the source of the activation instruction is a remote operation device of the source device, it is determined that the target of the activation instruction is the source device, and the source of the activation instruction is the remote operation device of the display device If there is, it is determined that the target of the activation instruction is a display device. Therefore, the user can promptly output the external content simply by giving a start instruction on the remote operation device of the source device, and similarly, the broadcast content can be obtained simply by giving a start instruction on the remote operation device of the display device. Can be output promptly.

  The source device according to aspect 4 of the present invention is the source device according to any one of the above aspects 1 to 3, wherein the external device control unit transmits the output setting of the display device in the startup preparation state. You may make it switch to the output setting according to a content.

  According to the above configuration, in the startup preparation state, the output setting of the display device is switched to the output setting corresponding to the content transmitted by the source device. Therefore, at the time of activation, the content can be appropriately output with the output setting corresponding to the content.

  The source device according to Aspect 5 of the present invention is the source device according to any one of Aspects 1 to 4, wherein the transition instruction unit activates the display device from a sleep state when the detection unit detects the presence of a user. While shifting to the ready state, other source devices that transmit content to the display device may also shift from the sleep state to the start-up ready state.

The device is shifted from the start preparation state to the start state. Therefore, when a predetermined condition for starting the display device is satisfied, the user can start the display device and quickly output the broadcast content without performing any operation.

  Moreover, according to said structure, if the predetermined conditions are not satisfied, a starting preparation state is maintained. Therefore, the user can also cause the display device and the source device to transition from the start preparation state to the start state by causing the display device to output external content quickly by giving a start instruction. That is, according to said structure, there exists an effect that it becomes possible to output a content rapidly at the timing according to a user's will.

  In the source device according to aspect 7 of the present invention, in the aspect 6, the predetermined condition is that the current time is included in a predetermined time zone, and the predetermined program is being broadcast or broadcast within a predetermined time from the current time.

Within at least one of the broadcast programs that have been reserved for viewing. Therefore, the display device can be automatically activated at a timing when the user is highly likely to view the broadcast content.

  For example, if the user is detected in such a time zone by setting a time zone such as a golden time when the user frequently views broadcast content as the predetermined time zone, the display device is automatically activated. Can be made. It is also possible to automatically activate the display device when a program that the user is continuously watching or a program that matches the user's preference is being broadcast or is broadcast within a predetermined time from the current time. Become. Furthermore, when there is a broadcast program that has been reserved for viewing within a predetermined time from the current time and the possibility that the user will view the broadcast program is very high, the display device can be automatically activated.

When the source device transitions from the hibernation state to the start-up preparation state, triggered by the state control unit (TV-side state control unit 42) that shifts the display device from the hibernation state to the start-up preparation state, When the activation instruction is received without going through the source device, the output target is the broadcast content, and when the activation instruction is received from the source device, the output control unit 44 sets the output target as the external content. And.

  According to said structure, when a source apparatus transfers to a starting preparation state from a hibernation state triggered by a user's detection, a display apparatus is changed to a starting preparation state from a hibernation state. Therefore, even if any content is output after the user is detected, the content can be output in a shorter time compared to the case of starting from the hibernation state.

  Also, according to the above configuration, in the start preparation state, when a start instruction is received without going through the source device, the output target is the broadcast content, and when the start instruction is received from the source device, the output target is set. External content. Therefore, according to said structure, the content along a user's will can be output. This is because when the activation instruction is received from the source device, it is highly likely that the user has operated the source device with the intention of outputting the external content, and conversely, when the activation instruction is received without going through the source device. This is because there is a high possibility that the user does not intend to output external content. That is, according to said structure, there exists an effect that the content along a user's will can be output rapidly.
