It is a figure which shows the relationship when the information transmission operation | movement of a recording / reproducing apparatus and an external terminal perform command transmission and information acquisition in order to demonstrate the operation example of other embodiment. It is a block diagram which shows the structural example of other embodiment.

  Hereinafter, embodiments will be described with reference to the drawings. In FIG. 1, reference numeral 1000 denotes a recording / playback apparatus. This recording / playback apparatus 1000 may be a single device or may be connected to a television receiver. Reference numeral 1001 denotes a remote controller (hereinafter simply referred to as a remote controller) for operating the recording / playback apparatus.

  An operation signal from the remote controller 1001 is received by the user operation input unit 100 and interpreted by the control unit (main controller) 212 in the control block 200. If the operation signal from the remote controller 1001 is a command to turn on the power, the power supply module 131 to which the plug 130 is connected is activated. As a result, the recording / reproducing apparatus 1000 is turned on. Note that the auxiliary power supply is always set to an on state for receiving a remote control signal or the like.

  Assume that the operation signal from the remote controller 1001 is a command for selecting a program from a broadcast signal. A high frequency signal from the antenna 101 is input to the tuner 102, and the tuner 102 receives the signal of the designated program, demodulates it, and supplies it to the AV signal processing unit 103. The AV signal processing unit 103 selectively performs various types of signal processing (scanning line number conversion, resolution conversion, luminance correction, hue adjustment, noise reduction processing, etc.) on the input signal and supplies the output signal to the monitor 400. To do.

  The control block 200 includes a GUI (graphic user interface) processing unit 211 and an EPG (electronic program guide) information processing unit 230. The EPG information processing unit 230 can acquire electronic program guide information via the network or the tuner 102. The acquired electronic program guide information is stored in the memory 120, for example. This electronic program guide information is updated as appropriate. When the user wants to see the program guide, the user operates the remote controller 1001 to request a menu. The control unit 212 analyzes the menu request and instructs the GUI processing unit 211 to output a menu video. For example, the GUI processing unit 211 reads the menu video data in the memory unit 120 and supplies it to the AV signal processing unit 103. Thereby, the menu image is displayed on the monitor 400. The menu image includes a program guide display item (icon). When the user performs a cursor operation, selects a program guide display item (icon), and presses the enter button, the GUI processing unit 211 reads the electronic program guide information from the memory 120 and supplies it to the AV signal processing unit 103. The AV signal processing unit 103 processes the input electronic program guide information, outputs it as a program guide, and supplies it to the monitor 400. As a result, the program guide is displayed on the monitor 400. When the user moves the cursor on the program guide, selects a desired program name (icon), and presses the enter button, the program is received and displayed.

  Even when a program is reserved for recording, the user operates an operation key for recording reservation. Then, since the program guide is displayed on the monitor 400 as described above, the user moves the cursor on the program guide, designates the desired program, and operates the enter button. Thereby, recording reservation of a desired program is possible. At this time, the storage medium of the recording destination can be designated. As the storage medium, an optical disc (DVD, Blu-ray disc) 112, hard disk 114, memory card 117, or the like can be designated. When recording / playback of a signal to / from the optical disk 112 is performed, the control block 200, the disk drive unit 111, and the AV signal processing unit 103 operate in cooperation. When signal recording / reproduction with respect to the hard disk 114 is performed, the control block 200, the hard disk drive unit 113, and the AV signal processing unit 103 operate in cooperation. When recording / playback of signals to / from the memory card 117 is performed, the control block 200, the reader / writer 115, and the AV signal processing unit 103 operate in cooperation.

  When access control of the storage medium described above is performed and playback processing is performed, the playback control processing unit 214 in the control block 200 performs overall operation. When the recording process is performed, the recording control processing unit 215 in the control block 200 performs an overall operation. For example, control of the operation timing of the AV signal processing unit 103 and the disk drive unit 111 or the hard disk 114 or the reader / writer 115 is performed. When playback or recording is performed, the playback processing unit 214 and the recording control unit 215 control playback or recording according to the playback mode and recording mode set by the setting mode processing unit 216. The setting mode includes double-speed playback, resolution change, and aspect ratio setting for playback, and resolution setting and recording speed mode setting for recording.

  The control block 200 further includes an automatic chapter generation unit 221, a chapter editing processing unit 222, a title and chapter reproduction processing unit 224, and a chapter information management unit 224. A tag list management unit 225 is also included.

  The automatic chapter generation unit 221 can set chapter delimiter information as a delimiter position at an arbitrary position in the content (for example, the start and end positions of a commercial or a position at regular intervals). Specifically, for example, the start and end positions of the commercial are created as elapsed time information from the start of the program. The elapsed time information (chapter information) is organized and tabulated by the chapter information management unit 224 together with the title name with the chapter. The chapter information is stored in the memory unit 120 together with the title name, for example.

  In the automatic chapter generator 221, chapters are generated when a chapter is generated while recording a program (content) received when a broadcast signal is received, or once received and recorded. In some cases, chapters are generated while a program (content) recorded in the above is reproduced. In either case, when generating chapter information, the user designates automatic chapter generation via a remote control or a menu screen. Whether or not the chapter automatic generation mode is set is managed by the setting mode processing unit 216. The user can also edit chapters. For example, when a chapter edit item is selected on the menu screen, the chapter edit processing unit 222 included in the control block 200 is activated. The chapter editing processing unit 222 controls the memory unit 120 so that the monitor 400 displays the title name for which chapter information is created. When the title is specified by the user, the recording medium and AV signal processing unit 103, the memory are created so that the monitor 400 displays the thumbnails at the beginning and end of the chapter with reference to the chapter information of the title. The unit 120 and the like are controlled. As a result, the user can specify a thumbnail with the cursor while viewing the monitor 400, specify a chapter, delete it, or perform editing such as merging.

  The control block 200 further includes a tag list management unit 225. The tag is defined as, for example, video period designation time information of a start time and an end time. The short video period may be, for example, one frame period or several tens of frame periods. This period need not be limited to such a short time.

  There are various methods for creating tag information. For example, there is a method of designating a tag identification name (which may be used as a tag list name, or a chapter name or an identification name input by itself) and a tag creation interval (time interval). Furthermore, it is possible to specify the time interval between the start and end of one tag. There is also a method of creating a tag at the beginning of a chapter using chapter information. The tag list management unit 225 collects tags created in this way, and creates tag list information (including a plurality of tag information pairs) for each title. The tag list management unit 225 transfers the created tag list to the memory unit 120 as tag list information for storage.

  The control block 200 is provided with a time information processing unit 231. The time information processing unit 231 is used to correct a time lag in operation between a user terminal 700 described later and the recording / playback apparatus 1000.

  The recording / reproducing apparatus 1000 is connected to the network 500 via the network control unit 300. A data management server 600 is connected to the network 500. A base station 800 is connected. The base station 800 and the user terminal 700 can communicate with each other. The user terminal 700 is a terminal that functions as, for example, a mobile phone.

  The data management server 600 can perform mutual communication with the recording device 100, the user terminal 700, and the like connected on the network. The data management server 600 includes a notification transmission / reception unit 601, a tag list management unit 603, and a database 604. The tag list management unit 603 manages tag information sent from the recording / playback apparatus 1000 together with, for example, a title name or a chapter name. Then, it can be stored in the database 604 as tag list information.

  The tag information format includes a title name and a tag list name in a layer below the title name. Therefore, a plurality of tag lists can be generated for one title. For example, user A and user B can create their own tag lists according to their preferences.

  The user terminal 700 includes a data transmission / reception unit 770. A user operation processing unit 701 is also included. The operation signal generated by the user operation is grasped by the user operation processing unit 701. When a screen for operation is required, the user terminal 700 has a liquid crystal or LED display unit and can activate the operation screen. Various image contents on the operation screen, image provision (image enlargement, reduction, etc.), image switching, and the like are controlled by the terminal screen display processing unit 702 according to the operation input. Further, a signal related to the telephone is processed by the telephone signal processing unit 703.

  The user terminal 700 also includes a video editing processing unit 711 and a time information processing unit 712. By using the video editing processing unit 711, the user can read video information of a desired title from the storage medium of the recording / reproducing apparatus 1000 and perform editing processing using the user terminal 700 while watching the monitor 400. . That is, the video editing processing unit 711 includes an application that transmits a video editing command to the recording / playback apparatus 1000. Accordingly, the user terminal 700 can be used as if the remote controller 1001 is operated. It is possible to perform deletion processing in the middle of content or processing for combining with other content by editing processing.

  The user terminal can register various devices to be operated in the setting information processing unit. The processing related to the setting information is operated mainly by the setting information processing unit. An application for operating the registered device is stored in the application file and is managed by the application management unit. The application management unit can generate an application list.

  The time information processing unit 712 detects a difference between the screen image on the monitor 400 and the time when the user terminal 700 is operated when editing processing, chapter creation, or the like is performed using the user terminal 700. Is provided. For example, it is assumed that images A, B, C, D, E, F, G, H, I,... Are output as images output from the recording / playback apparatus. It is assumed that the user transmits a pause operation at the time of image C, for example. Then, the recording / playback apparatus 1000 receives the pause signal, analyzes it, and actually pauses at the time when the image F is output. This is due to the transmission command from the user terminal 700 being transmitted via the network.

  Therefore, in this system, the user terminal 700 transmits absolute time information together with a temporary stop command signal. On the other hand, the recording / reproducing apparatus 1000 transmits absolute time information (the time when the suspension is performed) to the user terminal 700 together with the response signal when the suspension is performed. This absolute time information is monitored by the time information processing unit 231. The absolute time information is, for example, time information at a common current time point.

  The user terminal 700 determines whether or not the absolute time information transmitted from the recording / playback apparatus 1000 (the time at which the pause has been performed) is different from the absolute time information transmitted by the user terminal 700 (the time at which the pause operation has been performed). By operating the terminal 700, it is possible to know the time difference information until the temporary stop. Therefore, the time difference information is sent to the recording / reproducing apparatus 1000, and when the recording / reproducing apparatus 1000 performs a temporary stop in the future, the frame at the position returned by the time difference is reproduced and output as an image at the pause position. Further, when creating time information as a break position such as a chapter, time information for a chapter is created using time difference information and a time at a position advanced from the absolute time received from the user terminal 700.

  For the absolute time, it is preferable to use, for example, an output of a clock circuit having an automatic time adjustment function built in the recording / playback apparatus 1000 and the user terminal 700.

  In the above description, the user terminal 700 is a mobile phone, but it may be a personal computer. The data management server 600 may be a personal computer.

  2 and 3 are diagrams for explaining an operation example of this embodiment. The operation will be described below with reference to FIGS. It is assumed that the chapter of the content of title 1 has already been created in the recording / playback apparatus 1000. Then, chapter information (a plurality of time position information from the start position of the content) is created as chapter information by the automatic chapter generation unit 221, and the chapter information is stored in the memory unit 20 under the management of the chapter information management unit 224. It shall be.

  Now, assume that a tag creation icon is selected from the menu screen on the user terminal 700. Then, on the display unit of the user terminal 700, a list of recording / playback apparatuses 1000 or other recording / playback apparatuses registered as linked apparatuses is displayed. In this case, it is assumed that the user selects the recording / playback apparatus 1000. Next, on the display unit of the user terminal 700, a list of the data management server 600 registered as a cooperation apparatus is displayed. Assume that the user selects the data management server 600.

  Next, a plurality of title names for which tags are generated are transmitted to the user terminal 700 and displayed. These titles are titles recorded on the storage medium of the recording / reproducing apparatus 1000. Here, it is assumed that the user selects title 1 and transmits a command signal for generating a tag list. Then, the recording / reproducing apparatus 1000 shifts to the tag list generation mode by the setting operation of the setting mode processing unit 216.

  Next, when a playback command is transmitted from the user terminal 700 (steps SA1 and SA2 in FIG. 3), playback of the title 1 content is started (step SB1 in FIG. 3). When the desired scene is reached, when the user operates the user terminal 700 and operates the one stop button (step SA3 in FIG. 3), a temporary stop command signal is transmitted to the recording / playback apparatus 1000. As a result, the recording / reproducing apparatus 1000 is temporarily stopped (step SB2 in FIG. 3), and transmits a response signal to the user terminal 700. Here, the user terminal 700 transmits a skip down command signal as the chapter number (n = 0) (no chapter) as the current chapter (step SA5 in FIG. 3). Then, the recording / reproducing apparatus 1000 generates tag information corresponding to the chapter time information (first time of chapter 1 in FIG. 2) that reaches first by performing skip-down reproduction (step SB3 in FIG. 3). Tag related information including information and a tag identification name (may be a chapter name) is transmitted to the outside via the network control unit 300 (step SB4 in FIG. 3). The control unit 212 controls the network control unit 300 when transmitting the tag related information.

  The tag related information is sent to either or both of the data management server 600 and the user terminal 700. Information indicating that at least tag-related information has been sent to the outside from the recording / playback apparatus 1000 is sent to the user terminal 700. Therefore, the user terminal 700 can detect or detect that the tag related information is transmitted from the recording / reproducing apparatus 1000 to the outside.

  The data management server 600 or the user terminal 700 that has received the tag related information generates a tag list (see FIG. 2) using the tag related information. That is, in the memory of the user terminal 700 or the tag list management unit 603 of the data management server 600, a table of the tag list 1 is created for the title 1, and the first tag 1 (00: 00-0: 05 seconds) Tag 1 (n = 1) is created. Next, the process proceeds to acquisition of tag related information regarding the tag 2 (steps SA6 and SA7 in FIG. 3). That is, the user terminal 700 determines whether or not the chapter number (n) has reached the maximum value of the title being processed, and if it has not yet reached the maximum value, moves to the top of the (n + 1) th chapter. A skip-up command signal to be accessed is transmitted to the recording / reproducing apparatus 1000 (step SA8 in FIG. 3).

  When the recording / reproducing apparatus 1000 receives the skip-up command signal, the recording / reproducing apparatus 1000 jumps to the front of chapter 2 and starts reproduction. When the time information from the beginning (chapter delimiter information) is the time of chapter 2, tag information corresponding to this chapter time information is generated, and tag related information including this tag information and tag identification name is generated as the network control unit 300. (Step SB4 in FIG. 3). Various methods can be used for jump processing. For example, the time stamp in the content is played back at high speed, or rough prediction is made according to the number of crossing tracks, and the time stamp is detailed in the jump destination. It is a method of catching.

  When the head of the chapter 2 is detected, tag information corresponding to time information indicating the break is generated, and tag related information including the tag information and the tag identification name is transmitted to the outside via the network control unit 300. (Step SB4 in FIG. 3). Thereafter, the routine of steps SA6-SA7-SA8-SB5-SB4 in FIG. 3 is repeated and executed until the last chapter break. As for the last chapter delimiter information, the number of chapters is transmitted in advance from the chapter information management unit 224.

  With the above processing, for example, the tag list 1 related to the title 1 is generated. When the tag list 1 is constructed in the user terminal 700, the tag list is transferred to the data management server 600 and stored. Further, the tag list has been described as being constructed in the user terminal 700 or the data management server 600 simultaneously with the generation of the tag list. However, the present invention is not limited to this method, and at first, it may be constructed inside the recording / reproducing apparatus 1000 and transferred to the data management server 600 after completion.

  The tag list generated as described above and stored in, for example, the data management server 600 can be used not only by the above-described user (first user) but also by another user (second user). If the second user owns a similar user terminal (second user terminal) and registers identification information such as the recording / playback apparatus 1000 and the data management server 600 in the second user terminal. Each device can be controlled in the same manner as the first user.

  For example, it may be desired to reproduce the title 1 in the recording / playback apparatus 11000 using the tag list 1 stored in the data management server 600. In such a case, when the second user obtains the menu information from the tag list management unit 603 in the data management server 600 and selects a desired tag list (tag list 1), the tag list 1 becomes the recording / playback device. 1000. When the tag list playback mode is specified, the tag list 1 is specified, and a playback command signal is sent, the recording / playback apparatus 1000 starts playback based on the tag list 1.

  Thus, in this system, the tag list 1 created by the user 1 is stored in the external data management server 600. Therefore, another user 2 can access the data management server 600 and use the tag list 1 without creating a tag list by himself / herself.

  FIG. 4 shows a flowchart showing another operation example. The same parts in the flowchart of FIG. 4 and the flowchart of FIG. The difference between the flowchart of FIG. 4 and the flowchart of FIG. 3 is that the tag interval information (x) is transmitted at the same time when the skip-down command signal is transmitted (step SB5-1). This processing step is provided in order to increase the tag interval since many tags are generated if there are many chapters. The tag interval information includes a tag corresponding to an odd-numbered chapter, a tag corresponding to an even-numbered chapter, or information that specifies generation of a tag corresponding to a chapter at an arbitrary interval by specifying the number of jumps. The description of the other parts is the same as in the previous embodiment, and a detailed description thereof will be omitted.

  FIG. 5 shows an example of an environment in which the apparatus shown in the above embodiment is employed. The network 500 may be either a home network or an external network. It is also assumed that a home LAN 511 leading to each room is installed. It is assumed that a television receiver 400A is installed in the room A, and a recording / reproducing apparatus 1000A having a hard disk drive is connected to the television receiver 400A. In room B, it is assumed that a television receiver 400 and recording / reproducing apparatuses 1000 and 1001 are installed. The television receiver 400 is also used as a monitor as described with reference to FIG. Further, in the room C, a television receiver 400C is installed. A recording / reproducing apparatus 1000C having a hard disk drive is connected to the television receiving apparatus 400C. In the room C, an imaging camera 1500 is installed.

  Each of the above devices is connected to the home LAN 511, and the device identification information is registered in the user terminal 700. Therefore, the user terminal 700 can designate a desired device by the identification information and operate the designated device. The user terminal 700 may be prepared in each room. The user terminal 700A may be owned by a person who uses the room A, the user terminal 700B may be owned by a person who uses the room B, and the user terminal 700B may be owned by a person who uses the room C.

  Further, the home LAN 511 is connected to a control device 650 that performs power control of devices in the home, arbitration for data transmission / reception, and the like.

  It is assumed that device identification information such as the television receiving devices 400A and 400B, the hard disk drives 1002 and 1003, the plurality of recording / reproducing devices 1000 and 1001, and the data management server 600 is registered in the user terminal 700. Therefore, if the user terminal 700 designates device identification information and sends a control command signal, any device can be controlled. For example, power on / off of the television receiver 400A, channel switching, and the like. As for the operation of the hard disk drive 1002, the same operation as the operation for the recording / reproducing apparatus 1000 described above can be performed.

  The data management server 600 may be installed in a remote place outside the house, or may be installed in the house.

  The user terminal 700 may communicate with each device via an external base station, or may directly communicate with the television receiving device 400 using infrared as a medium. As a result, there may be a discrepancy between the video with the tag desired by the user and the video with the tag on the receiving device or recording / playback device side. In such a case, the deviation can be prevented in the present embodiment. This is because the chapter time already obtained is used.

  With the above configuration, if the tag list is stored in the data management server 600, for example, other users can access using the same user terminal.

  In addition, various methods have been developed as communication methods between various devices connected to the network, and either method may be used or a combination may be used. Each device is assigned an IP address, and is provided with an authentication function between devices.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
