Description

  The present invention relates to a content reproduction system including a content reproduction device and a content reception device.

  A plurality of content playback devices (for example, a DVD player, an HDD recorder, etc.), a plurality of display devices, and a plurality of speakers can be connected to the AV amplifier. For example, as shown in FIG. 10, an AV amplifier 20, a DVD player 10A, an HDD recorder 10B, a display device 30A, a speaker 60A, and a remote control receiver 24A are arranged in the main room ZONE1, and a display device 30B is arranged in the subroom ZONE2. A speaker 60B and a remote control receiver 24B are arranged. The AV amplifier 20 is provided with a selector for a main room and a subroom (DVD selector, HDD selector). By selecting the selector for the main room and the selector for the subroom, the video is displayed in the main room ZONE1 and the subroom ZONE2. In addition, it is possible to select a content playback apparatus that plays back audio. For example, when the DVD is selected as the main room selector and the HDD is selected as the sub room selector, the video and audio of the DVD player 10A are reproduced in the main room ZONE1, and the video and audio of the HDD recorder 10B are reproduced in the subroom ZONE2. Played. When the HDD for both the main room selector and the sub room selector is selected, the video and audio of the HDD recorder 10B are reproduced in both the main room ZONE1 and the sub room ZONE2.

  Here, the DVD player 10A and the HDD recorder 10B are provided with a resume function, and when reproduction is stopped at a certain reproduction position (reproduction time) (of a certain content), the reproduction position is stored in the memory as resume information. The reproduction can be started from the reproduction position specified by the stored resume information when the reproduction instruction is input next time. However, as described above, when the video data and audio data of the same content reproduction device can be reproduced in the main room ZONE1 and the subroom ZONE2, the following problems occur. That is, when the DVD player 10A stops playback at a playback position of 10:00, for example, by a user operation of the main room ZONE1, the DVD player 10A stores the playback position 10:00 in the memory as resume information. Next, when the DVD player 10A is reproduced by a user operation of the subroom ZONE2, the DVD player 10A erases the reproduction position 10:00 which is resume information in the memory. For example, when playback is stopped at the playback position of 20:00, the DVD player 10A newly stores the playback position 20:00 in the memory as resume information. Next, when the DVD player 10A is played again by the user operation of the main room ZONE1, the playback position 20:00 is stored as resume information, although the user understands that playback will start from 10:00. Therefore, the reproduction is started from 20:00, and the user feels uncomfortable.

  Further, when the DVD selector is selected in the main room ZONE1 and the DVD player 10A is playing back, if the selector in the main room ZONE1 is changed to the HDD selector, the DVD player 10A continues to play back. Therefore, when the selector of the main room ZONE1 is changed to the DVD selector again, the DVD player 10A cannot restart the playback from the position where the playback was performed before the change to the HDD selector. When the selector of the main room ZONE1 is changed to the HDD selector, the reproduction of the DVD player 10A may be stopped or temporarily stopped by the user operation. However, when the DVD player 10A is started to be reproduced by the user operation of the subroom ZONE2, Again, when the selector of the main room ZONE1 is changed to the DVD selector again, the DVD player 10A cannot resume playback from the position where it was played before changing to the HDD selector.

  Further, when the DVD selector is selected in the main room ZONE1 and the DVD player 10A is playing back, when the AV amplifier 20 is switched from the power-on state to the standby state, the DVD player 10A continues to play back. Therefore, when the AV amplifier 20 is switched from the standby state to the power-on state again, the playback cannot be resumed from the position where the DVD player 10A was playing before the standby state. When the AV amplifier 20 is switched from the power-on state to the standby state, the reproduction of the DVD player 10A may be stopped or temporarily stopped by the user operation. However, when the DVD player 10A is started to be reproduced by the user operation of the subroom ZONE2, Again, when the AV amplifier 20 is switched from the standby state to the power-on state again, the playback cannot be resumed from the position where the DVD player 10A was playing before the standby state.

The operation display unit 25 is an operation switch provided on the front panel of the AV amplifier 20, which receives an operation signal by a user operation in the main room ZONE 1 and supplies the operation signal to the system control unit 23. Similarly, the operation signal includes an instruction to change the selector for each room, an instruction to start reproduction, an instruction to set the AV amplifier 20 in a standby state, an instruction to set the AV amplifier 20 in a power-on state, and the like.

  The system control unit 23 includes an HDMI receiving unit 21, an HDMI transmitting unit 22, an operation display unit 25, an audio processing unit 26, a memory 28, and the like based on an AV amplifier operation program stored in a built-in or connected memory. For example, a microcomputer or a CPU is controlled. The system control unit 23 executes various processes based on operation inputs from the operation display unit 25 and the remote control receivers 24A and 24B or control signals and data from each unit. The system control unit 23 is connected to the system control unit 14 of the DVD player 10 via the CEC line, and transmits and receives commands and data to and from the system control unit 14.

  When an instruction to change the selector of the main room ZONE1 or the subroom ZONE2 is input, the system control unit 23 requests and obtains resume information from the content playback device corresponding to the currently selected selector (the selector before the change). To do. The acquired resume information is stored in the resume information table shown in FIG.

  The resume information table can store resume information for each selector in each room. As shown in FIG. 3, the DVD selector of the main room ZONE1 has the resume information REDVD1 of the DVD player 10A, the HDD selector of the main room ZONE1 has the resume information REHDD1 of the HDD recorder 10B, and the DVD selector of the subroom ZONE2 has the DVD player. Resume information REDVD2 of 10A is stored, and resume information REHDD2 of the HDD recorder 10B is stored in the HDD selector of the subroom ZONE2.

  That is, when an instruction to change the selector of the main room ZONE1 to the HDD selector (from the DVD selector) is input, the system control unit 23 acquires the resume information of the DVD player 10A, and the DVD selector of the main room ZONE1 in FIG. Register in the field. When an instruction to change the selector of the subroom ZONE2 to the DVD selector (from the HDD selector) is input, the system control unit 23 acquires the resume information of the HDD recorder 10B and registers it in the field of the HDD selector of the subroom ZONE2 in FIG. .

  When an instruction to change the selector of the main room ZONE1 or the subroom ZONE2 is input, the system control unit 23 checks whether the resume information of the selector after the change is stored in the resume information table of FIG. If so, the resume information is read out and transmitted to the content reproduction apparatus. For example, when an instruction to change the selector to the HDD selector (from the DVD selector) for the main room ZONE1 is input, the system control unit 23 stores the resume information in the HDD selector field of the main room ZONE1 in the resume information table. Then, the resume information is transmitted to the HDD recorder 10B.

  In addition, when an instruction to change the selector to the DVD selector (from the HDD selector) for the subroom ZONE2 is input, the system control unit 23 may store the resume information in the DVD selector field of the subroom ZONE2 in the resume information table. Then, the resume information is transmitted to the DVD player 10A.

  At this time, when the content of the DVD player 10A is being reproduced in the main room ZONE1, if the resume information stored in the DVD selector field of the subroom ZONE2 is transmitted to the DVD player 10A, the reproduction position of the DVD player 10A is It is changed to the reproduction position specified by the resume information for the sub-room ZONE2 transmitted. Then, the user who is playing the content of the DVD player 10A in the main room ZONE1 is uncomfortable. Therefore, as an example, when the playback position of the main room ZONE1 is prioritized and the resume information of the subroom ZONE2 is transmitted to the DVD player 10A later, the selectors of the main room ZONE1 are the same selector (DVD selector). This problem can be solved by not transmitting the resume information of the subroom ZONE2 to the DVD player 10A. On the other hand, when the resume information of the main room ZONE1 is transmitted later, it may be transmitted unconditionally to the DVD player 10A regardless of the selector of the subroom ZONE2.

Hereinafter, the operation of the content reproduction system of this embodiment will be described.
[Selector change processing for main room ZONE1]
4 is a flowchart showing the process of the system control unit 23 of the AV amplifier 20, and FIG. 5 is a flowchart showing the process of the system control unit 14 of the DVD player 10A or the HDD recorder 10B. In this example, the case where the selector of the main room ZONE1 is changed from the DVD selector to the HDD selector will be described as an example.

  As shown in FIG. 4, the system control unit 23 monitors whether or not a selector change instruction for the main room ZONE1 is input by a user operation (S1), and an instruction to change from the DVD selector to the HDD selector is input. (YES in S1), the system control unit 23 transmits a selector release notification via the CEC line to the system control unit 14 of the content playback apparatus (DVD player 10A) of the currently selected selector (S2). As shown in FIG. 5, the system control unit 14 of the DVD player 10A monitors the reception of the selector release notification (S41). When the selector release notification is received (YES in S41), the current content in the playback unit 11 is displayed. Is transmitted as resume information to the system control unit 23 of the AV amplifier 20 via the CEC line (S42). Even when the playback unit 11 stops playback, if the playback stop position is stored in the memory, the playback stop position may be transmitted as resume information. As shown in FIG. 4, when the system control unit 23 of the AV amplifier 20 receives the resume information from the system control unit 14 of the DVD player 10A, the resume information received in the DVD selector field of the main room ZONE1 of the resume information table. Register (S3). If resume information has already been stored, the stored resume information is deleted and the currently acquired resume information is registered (overwritten).

  Subsequently, the system control unit 23 determines whether or not the currently selected selector (DVD selector) is also selected in the subroom ZONE2 with reference to the selector table of FIG. 2 (S4). That is, it is determined whether or not the content of the same content playback device is currently being played back in the main room ZONE1 and the subroom ZONE2. When the selector of the sub room ZONE2 is a DVD selector as in the main room ZONE1 (YES in S4), the process proceeds to S6. On the other hand, if the selector of the sub room ZONE2 is an HDD selector unlike the main room ZONE1 (NO in S4), the content from the DVD player 10A will not be output to the main room ZONE1 or the subroom ZONE2, so the system control unit 23 Transmits a power-off command to the system control unit 14 of the DVD player 10A via the CEC line (S5). As shown in FIG. 5, the system control unit 14 of the DVD player 10A monitors the reception of the power-off command (S50). When the power-off command is received (YES in S50), the system controller 14 indicates that it is in the standby state. After notifying the system control unit 23 of the amplifier 20, the power-on state is changed to the standby state (S51). The system control unit 23 of the AV amplifier 20 manages on the memory whether the DVD player 10A and the HDD record 10B are in a power-on state or a standby state.

  Here, the AV amplifier 20 and the content reproduction apparatus 10 include a main power supply circuit that supplies power supply voltage to the entire apparatus, and a standby power supply circuit that supplies power supply voltage only to the system control unit and its peripheral circuits. In the on state, both the main power supply circuit and the standby power supply circuit are turned on. In the standby state, the main power supply circuit is turned off and the standby power supply circuit is turned on. In the power-on state, content playback, content transmission / reception, and other processes can be executed. In the standby state, content playback, content transmission / reception, and other processing cannot be executed, but a transition to the power-on state can be made by a remote control signal, a power-on command, or the like.

  As shown in FIG. 4, the system control unit 23 of the AV amplifier 20 changes the selector of the main room ZONE1 from the DVD selector to the HDD selector (S6). That is, the system control unit 23 controls the HDMI receiving unit 21 so as to select the HDMI data from the HDD recorder 10B as the content to be output to the main room ZONE1. Further, the system control unit 23 rewrites the field of the main room ZONE1 in the selector table of FIG. 2 to the HDD selector that is the selector after the change.

  Subsequently, the system control unit 23 determines whether or not the changed content playback device (HDD recorder 10B) of the selector is in a power-on state (S7). If the HDD recorder 10B is in the power-on state (YES in S7), the process proceeds to S9. On the other hand, when HDD recorder 10B is in a standby state (NO in S7), system control unit 23 transmits a power-on command to system control unit 14b of HDD recorder 10B via the CEC line (S8). As shown in FIG. 5, the system controller 14b of the HDD recorder 10B monitors whether or not a power-on command has been received (S43). When the power-on command is received (YES in S43), Transition to the power-on state (S44).

  Subsequently, the system control unit 23 monitors whether or not a playback instruction is input by a user operation for the content playback device (HDD recorder 10B) of the selector after the change (S9), and the playback instruction is input. In the case (YES in S9), the system control unit 23 transmits a playback command to the system control unit 14b of the HDD recorder 10B (S10). Furthermore, the system control unit 23 determines whether resume information is stored for the content playback device (HDD recorder 10B) of the selector after the change (S11). That is, the system control unit 23 determines whether resume information is stored in the HDD selector field of the main room ZONE1 of the resume information table. When the resume information is stored in the resume information table (YES in S11), the system control unit 14 reads the resume information from the resume information table, and via the CEC line, the system control unit 14b of the HDD recorder 10B. (S12).

  As shown in FIG. 5, the system control unit 14b of the HDD recorder 10B monitors the reception of the playback command (S45). When the playback command is received (YES in S45), the resume information is received from the system control unit 23. It is determined whether it has been done (S46). When the resume information is received (YES in S46), the system control unit 14b starts to play the content from the playback position included in the resume information. Specifically, for example, since the resume information includes a content ID for specifying the content and a playback start position (playback time, playback start address), the playback unit 11b plays back the playback start position of the content specified by the content ID. Playback starts from the position specified by.

[Sub-room ZONE2 selector change process]
FIG. 6 is a flowchart showing selector change processing of the sub-room ZONE 2 by the system control unit 23 of the AV amplifier 20. The selector changing process for the sub room ZONE 2 is substantially the same as the selector changing process for the main room ZONE 1 described with reference to FIG. 4, and the terms “main room” and “sub room” shown in FIG. 4 are interchanged. If the selector of the subroom ZONE2 is changed from the DVD selector to the HDD selector and it is determined in S31 that the resume information is stored in the HDD selector field of the subroom ZONE2 in the resume information table (YES in S31), the system. The control unit 23 refers to the selector table to determine whether the changed selector (HDD selector) is the same as the selector of the current main room ZONE1 (S32). When the selector (HDD selector) of the changed sub room ZONE2 is the same as the selector of the current main room ZONE1 (YES in S32), the system control unit 23 does not transmit resume information to the system control unit 14b of the HDD recorder 10B. As shown in FIG. 5, when the system control unit 14b of the HDD recorder 10B does not receive resume information within a predetermined time (NO in S46), for example, the content is currently being played back (that is, the content is not displayed in the main room ZONE1). It is determined whether or not the reproduction is in progress (S48). If playback is in progress (YES in S48), playback continues at the playback position as it is, so that the user of the main room ZONE1 is not uncomfortable. If playback is not in progress (NO in S48), for example, playback is started from the playback position of the content newly specified by the user operation, or playback is started from the first position of the first content (S49). The first content is, for example, the first content in the playlist or the content specified by the first content ID among all recorded content.

  As described above, according to the present embodiment, the resume information is stored in association with each selector of each room, so the content from the playback position specified by the resume information when the selector is changed for each room. Can be played. Note that the process of S9 may be omitted and a playback command may be automatically transmitted.

[Another embodiment 1]
Next, another preferred embodiment of the present invention will be described. FIG. 7 is a flowchart showing selector change processing of the main room ZONE1 of the AV amplifier 20 in this example, and the same processing as that in FIG. FIG. 8 is a flowchart showing selector change processing of the sub-room ZONE2 of the AV amplifier 20 in this example, and the same processing as that in FIG.

  In this example, as shown in FIG. 7, when it is determined in S11 that the resume information corresponding to the changed selector is stored in the resume information table for the main room ZONE1 (YES in S11), the system control unit 23 determines whether or not a resume reproduction permission instruction is input by the user operation for the main room ZONE1 (S13). For example, a question “Do you want to resume playback” may be displayed on the display device 30A arranged in the main room ZONE1, and whether or not to allow resume playback may be input by a user operation. The permission / inhibition of resume playback may be set from a menu screen or the like.

  When the resume playback permission instruction is input (YES in S13), the system control unit 23 reads the resume information corresponding to the changed selector and transmits it to the system control unit of the content playback device of the changed selector. (S12). On the other hand, when the resume reproduction disable instruction is input (NO in S13), the system control unit 23 does not transmit the resume information corresponding to the changed selector to the content reproduction apparatus.

  Similarly, as shown in FIG. 8, when it is determined in S31 that the resume information corresponding to the changed selector is stored in the resume information table for the subroom ZONE2 (YES in S31), the system control unit 23 Then, it is determined whether or not a resume reproduction permission instruction is input by the user operation for the sub room ZONE2 (S34). When the resume playback permission instruction is input (YES in S34), the system control unit 23 reads the resume information corresponding to the changed selector and transmits it to the system control unit of the content playback device of the changed selector. (S33). On the other hand, when the resume reproduction disable instruction is input (NO in S34), the system control unit 23 does not transmit the resume information corresponding to the changed selector to the content reproduction apparatus.

[Another embodiment 2]
Next, still another preferred embodiment of the present invention will be described. In this example, the resume playback permission instruction / resume playback disabling instruction is not input by the user operation on the AV amplifier 20 side as in FIGS. 7 and 8, but the resume playback permission instruction / Resume playback disabled instruction is input. For example, the selector changing process of the main room ZONE1 of the AV amplifier 20 is the same as that in FIG. 4, and the selector changing process of the sub room ZONE2 of the AV amplifier 20 is the same as that shown in FIG. That is, the AV amplifier 20 transmits the resume information unconditionally to the content reproduction device as long as the resume information is stored. In the processing of the content reproduction apparatus, after it is determined YES in S46 in FIG. 5, it is determined whether or not a resume reproduction permission instruction is input by a user operation. When the resume playback permission instruction is input, the process proceeds to S47 and playback is performed based on the resume information. However, when the resume playback disable instruction is input, the process proceeds to S48 and playback is not performed based on the resume information.

[Another embodiment 3]
Next, still another preferred embodiment of the present invention will be described. FIG. 9 is a flowchart showing a resume reproduction process when the AV amplifier 20 shifts from the standby state to the power-on state.

  When the system control unit 23 controls the main power supply circuit to be in the off state and shifts the AV amplifier 20 from the power on state to the standby state (YES in S61), the system control unit 23 is currently selected by the selector of the main room ZONE1. A standby notification indicating that the AV amplifier 20 shifts to the standby state is transmitted to the content playback device and the content playback device selected by the selector of the sub-room ZONE 2 (S62). For example, if the selector of the main room ZONE1 is a DVD selector, the system control unit 23 transmits a standby notification to the system control unit 14 of the DVD player 10A. If the selector of the subroom ZONE2 is an HDD selector, the system control unit 23 transmits a standby notification to the system control unit 14b of the HDD recorder 10B. In FIG. 5, S41 is replaced with “standby notification reception”, and the system control unit 14 of the content playback apparatus that has received the standby notification responds to the standby notification and uses the current playback position as resume information to perform system control of the AV amplifier 20. The data is transmitted to the unit 23 (S42). When receiving the resume information, the system control unit 23 registers the resume information in the resume information table in association with the current selectors of the main room ZONE1 and the subroom ZONE2 (S63). That is, in the resume information table, the resume information of the DVD player 10A is registered in the field of the DVD selector 10A of the main room ZONE1, and the resume information of the HDD recorder 10B is registered in the field of the HDD selector 10B of the subroom ZONE2. Thereafter, the system control unit 23 shifts from the power-on state to the standby state.

  On the other hand, when the system control unit 23 controls the main power supply circuit to turn on and shifts the AV amplifier 20 to the power on state (YES in S64), the system control unit 23 associates it with the selected selector of the main room ZONE1, It is determined whether or not the resume information is stored in the resume information table (S65). For example, if the selector of the main room ZONE1 is a DVD selector, it is determined whether the resume information of the DVD sector of the main room ZONE1 is stored. When the resume information is stored (YES in S65), the system control unit 23 reads the resume information from the resume information table and transmits it to the content playback device (DVD player 10A) of the selected selector in the main room ZONE1. (S66). If the resume information is not stored (NO in S65), the process proceeds to S67 without transmitting the resume information to the content reproduction device of the selected selector in the main room ZONE1.

  Subsequently, the system control unit 23 determines whether or not the subroom ZONE2 setting is on (S67). The subroom ZONE2 setting is a function for setting in advance by a user operation whether or not the AV amplifier 20 outputs content to the subroom ZONE2. ON / OFF of the subroom ZONE2 setting is managed by a flag in the memory, for example.

  If the subroom ZONE2 setting is off, the process ends. If the subroom ZONE2 setting is on (YES in S67), the system control unit 23 associates the resume with the selected selector of the subroom ZONE2. It is determined whether the information is stored in the resume information table (S68). If the selector of the subroom ZONE2 is an HDD, it is determined whether the resume information of the HDD selector of the subroom ZONE2 is stored. If the resume information is not stored, the process ends. If the resume information is stored (YES in S68), for example, the system control unit 23 indicates that the selector of the sub-room ZONE2 is the same as the selector of the main room ZONE1. It is determined whether or not there is (S69). If they are the same, the process ends in order to give priority to the resume information of the main room ZONE1. On the other hand, if they are not the same (NO in S69), the resume information is read from the resume information table and transmitted to the content reproduction device of the selector selected in the subroom ZONE2 (S70).

  With the above processing, even when the AV amplifier shifts to the power-on state, the content playback apparatus can be played back based on the resume information stored when the AV amplifier shifts to the standby state. Note that the resume reproduction process at the time of power-on in S64 to S70 may be executed based on the resume information stored in the resume information table when the selector is changed as shown in FIGS.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. For example, the reproduction unit 11 includes two optical pickups, etc., so that the reproduction start position for the main room ZONE1 is changed even when the contents of the same content reproduction apparatus are output to the main room ZONE1 and the subroom ZONE2 at the same time. And the reproduction start position for the subroom ZONE2 can be made different. In this case, it is not necessary to prioritize the resume information of the main room ZONE1 as in the above-described embodiment and to determine the input of the resume playback permission instruction / resume playback disabled instruction by the user operation. Further, the number of subrooms is not limited to one, and can be applied to a plurality of subrooms ZONE3 and ZONE4. Also, the content transmitted to the AV amplifier may be transmitted via an optical digital cable or the like instead of being transmitted via an HDMI cable. In this case, each command may be transmitted separately via another communication cable. Further, the program may be provided in the form of a program for causing a computer to execute the above-described operations of the AV amplifier and the content reproduction apparatus and a recording medium on which the program is recorded. Further, a program for only a part of the operation of the AV amplifier may be provided to the AV amplifier in the form of firmware update. Furthermore, it may be provided in the form of an electronic component such as a CPU or a microcomputer that stores a program for only a part of the above operation of the AV amplifier.

The present invention can be suitably employed in AV amplifiers, DVD players, and the like.
