<Embodiment 1>
An example of a preferred embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 101 denotes a digital video camera with a recording / playback function configured to be connectable to an IEEE 1394 standard cable, and 102 is an IEEE 1394 cable. Reference numeral 103 denotes a digital television configured to be connectable with an IEEE 1394 cable, and the digital video camera 101 is an external device when viewed from the digital television 103. That is, as shown in FIG. 1, the digital television 103 and the digital video camera 101 are connected by the IEEE 1394 cable 102. The digital video camera 101 connected in this way can perform various operations according to various control commands defined by the IEEE 1394 standard through a GUI (Graphic User Interface) on the display screen 104 of the digital television 103.

  For example, an operation button icon as shown in FIG. 2 is displayed, and the icon is clicked using the remote controller 105. Then, a command for instructing a reproduction operation is sent to the digital video camera 101, and the digital video camera 101 receives the reproduction command and controls the reproduction operation. Then, the reproduced digital video signal is output as isochronous data to the digital television 103 side through the IEEE 1394 cable in accordance with the format defined by the IEEE 1394 standard.

  Hereinafter, the video equipment control apparatus according to the first embodiment of the present invention will be sequentially described. FIG. 3 is a block diagram of the video equipment control apparatus according to the first embodiment suitable for use in the present invention. The broadcast receiving circuit 301 receives a digital television broadcast wave from a TV antenna or cable, supplies audio information to the audio reproduction circuit 302, and supplies video information to the video reproduction circuit 304. Also, electronic program guide information is superimposed on the digital television broadcast wave, and the electronic program guide information extracted by the broadcast receiving circuit 301 is supplied to the electronic program guide control circuit 307. Digital broadcasts received by the broadcast receiving circuit 301 include terrestrial digital broadcasts, broadcast satellite digital (BS digital) broadcasts, communication satellite digital (CS digital) broadcasts, wired digital broadcast waves, and the like. Even if it uses, this invention can be implemented.

  In this embodiment, the description is based on the IEEE 1394 standard cable connection. However, the standard is not necessarily limited to the IEEE 1394 standard, and the type of the standard is not limited as long as similar commands are included in the standard. If possible, it is also conceivable to construct a network by wireless connection. However, in this description, the cable connection of the IEEE 1394 standard is described as an example.

  Also, in terrestrial analog broadcasting, a specific broadcasting station distributes an electronic program guide. Therefore, the present invention can be implemented using an electronic program guide in terrestrial analog broadcasting. In the description of the present embodiment, the description will be made in relation to an electronic program guide for digital broadcasting. However, the present invention is not limited to the electronic program guide for digital broadcasting, and is applicable to an electronic program guide for terrestrial analog broadcasting. It can be done.

  Returning to FIG. 3 and continuing the explanation, the audio reproduction circuit 302 converts the audio information supplied from the broadcast receiving circuit 301 into an audio signal and outputs it from the speaker 303. The video reproduction circuit 304 generates a reproduction video signal from the video information supplied from the broadcast reception circuit 301 or the communication circuit 309 and supplies the reproduction video signal to the video signal synthesis circuit 305. The control circuit 308 receives operation information corresponding to the device operation from the user or the operation by the remote controller 105 from the operation signal generation circuit 310 and supplies it to the electronic program guide control circuit 307. The communication circuit 309 is compatible with the IEEE 1394 standard, and receives status commands for acquiring functions of external devices such as the digital video camera 101 connected via the IEEE 1394 cable 102 and control commands for controlling external devices. Issue.

  The electronic program guide control circuit 307 determines an electronic program guide item to be added according to the function of the external device connected to the communication circuit 309 via the IEEE 1394 cable 102, and the electronic program guide table acquired from the broadcast receiving circuit 301. An electronic program guide screen is generated in combination with the information. The video signal synthesis circuit 305 synthesizes the playback video supplied from the video playback circuit 304 and the electronic program guide screen generated by the electronic program guide control circuit 307 and displays them on the display unit 306. The video information received by the communication circuit 309 is supplied to the video reproduction circuit 304 and is finally displayed on the display screen 104 of the display unit 306 as a video signal. In this description, an example in which the display unit 306 is integrated with the main body of the digital television 103 is shown, but a combination of a so-called tuner and a monitor may be used.

  Next, the electronic program guide screen will be described. The electronic program guide returns to the broadcast viewing screen from the “cursor button” and the “decision button” for decision making provided on the digital television 103 main body or the remote controller 105 and the decision-making “decision button” and the electronic program guide. It can be controlled with the "return button" for

  FIG. 5 is an example of an electronic program guide screen generated from electronic program guide information duplicated in digital broadcast waves. The character string “time” 501 means time axis information, and expresses that the time axis display unit 502 displayed below the character string “time” 501 displays time information. For example, in order to make the user recognize that a program at a specific time on a specific channel is selected on the electronic program guide screen, the part is surrounded by a thick line or the display state is different from other parts. There is a focus display function.

  That is, for the channel name display units 503, 504, and 505 and the program content display unit 506 arranged below these channel name display units, the “cursor button” of the remote controller 105 described above is used to display the focus display position. Can be moved. The “return button” is pressed in a state where the focus is displayed on the channel name display sections 503, 504, 505 or the program content display section 506. Then, the selected broadcast channel is notified from the electronic program guide control circuit 307 to the broadcast receiving circuit 301. Then, the video information and audio information of the selected broadcast channel are supplied to the video reproduction circuit 304 and the audio reproduction circuit 302, respectively, and the user can view the video and audio of the selected broadcast channel. .

  The program content display unit 506 displays the content of the program corresponding to the time at which each broadcast channel is displayed, and viewing reservation can be made by pressing the “decision button” of the remote controller 105. For example, if the “decision button” of the remote controller 105 is pressed while the program content display section 506 is focused, channel 7 is reserved for viewing from 11:00 am to 12:00 am. Therefore, at 11 am, the broadcast channel received by the broadcast receiving circuit 301 is automatically switched to channel 7.

  In addition, when a right movement is instructed with the “cursor button” of the remote controller 105 in a state where the focus is displayed on the channel 7, one item being displayed or all the items being displayed are shifted to the left, and cannot be displayed. Show broadcast channels hidden in the. As a result, it is possible to display the electronic program of the broadcast channel that cannot be displayed in one screen. Similarly, when a downward movement is instructed with the “cursor button” of the remote controller 105 in a state where the focus is displayed at the bottom of the program content on the screen, the program at the next time zone can be displayed.

  Next, the flow of the electronic program guide screen generation process in the embodiment of the present invention will be described with reference to the flowchart shown in FIG. When the display of the electronic program guide is instructed by the operation of the remote controller 105 by the user, the electronic program guide screen generation processing in step S401 starts. After starting the electronic program guide screen generation process, first, electronic program guide information is acquired through the broadcast receiving circuit 301 in step S402. At this time, the electronic program guide information may be acquired through the broadcast receiving circuit 301, or the electronic program guide information acquired in advance by the broadcast receiving circuit 301 and stored in the electronic program guide control circuit 307 may be used.

  In step S 403, it is confirmed whether an external device is connected to the communication circuit 309 via the IEEE 1394 cable 102. If no external device is connected via the IEEE 1394 cable 102, the process proceeds to step S408, and an electronic program guide screen is generated according to the electronic program guide information acquired in step S402. However, if an external device is connected to the communication circuit 309 via the IEEE 1394 cable 102 in step S403, the process proceeds to step S404. Then, a function supported by an external device (in the case of FIG. 1, the digital video camera 101) connected via the IEEE 1394 cable 102 is acquired. For example, it is checked using “SUBUNIT INFO status command” of the IEEE 1394 standard.

  In other words, if the function supported by the control circuit 308 of the digital television 103 corresponds to “Tape recorder / player subunit”, “Camera subunit”, and “Camera Storage subunit”, the response of “SUBUNIT INFO status command” Contains the subunit ID described above. In step S405, it is confirmed whether a usable function is included in the response of the “SUBUNIT INFO status command”.

  If the digital television 103, which is the video equipment control apparatus of the present embodiment, supports one or more of the functions included in the response, it notifies the electronic program guide control circuit 307, and the electronic program guide is displayed in step S406. Add the function item of the external device. In step S407, it is confirmed whether there are any other undetected externally connected devices connected via the IEEE 1394 cable 102.

  For example, the digital video camera 101 has a tape recording / playback function, a camera function, a still image recording / playback function, and the like. Usually, a magnetic tape is used for recording and reproducing moving images, and a semiconductor memory is used for recording and reproducing still images. Recently, models using recordable DVDs (Digital Versatile Disks), HDDs, and the like are on the market, and the present invention can be applied to these as external devices. If the function included in the response is not supported in step S405, the process proceeds to step S407 without adding an item to the electronic program guide, and another undetected external device connected via the IEEE 1394 cable 102 is added. Check for connected devices. If an unconfirmed externally connected device is detected, the process returns to step S404, and a function supported by the currently unconfirmed externally connected device is acquired. Thus, when the functions of all the externally connected devices are acquired and the items to be added to the electronic program guide are determined, the process proceeds to step S408, and the electronic program guide control circuit 307 generates an electronic program guide screen.

  An electronic program guide screen generated by the procedure described in the flowchart shown in FIG. 4 is shown in FIG. 6 as an example. The same parts as those in the electronic program guide screen of FIG. 5 use the same numbers, and a detailed description thereof is omitted. The channel name display section 601 of the external device connected via the IEEE 1394 cable 102 displays the external device name and the mode to be used. At that time, functions that can be used by the externally connected device are also displayed. For example, “-VCR-” means, for example, the function of the tape recording / reproducing device of the model name SLD 51 of the digital video camera 101 in FIGS. To do.

  When the user operates the electronic program guide screen shown in FIG. 6, the “switch button” for switching between device control of the digital television 103 main body or the remote controller 105 and the broadcast program is pressed. Accordingly, the focus display position can be switched between the broadcast program display unit and the external device control display unit. Similarly to the broadcast program display unit, the external device control display unit returns to the broadcast viewing screen from the “cursor button” of the main body of the digital television 103 or the remote controller 105, the “decision button” for decision making, and the program guide screen. It can be controlled with the “return button”.

  In the state shown in FIG. 6 in which the focus display position is in the channel name display portion 503 and the channel 5 is in the selected state, the “switch button” for device control / broadcast switching is pressed. Then, as shown in FIG. 7, the focus display position moves to the device control display unit, and the focus display position moves to the external device control display unit 601. Further, the display of the time axis display unit 502 and the character string “time” 501 in the meaning of the time axis disappears, and the time display is switched according to the function used by the external device.

  In the example of FIG. 7, the time axis information becomes a character string “reproduction time” 602 indicating the reproduction time, and the total reproduction of all contents recorded on the magnetic tape loaded in the external device 101 is displayed as the time axis. The time display unit 603 is the vertical axis. Further, a position marker 604 indicating the current magnetic tape reproduction position or the current position of the magnetic tape is displayed. The maximum value of the time axis at this time may be the total reproduction time of all the contents recorded on the magnetic tape or the time converted from the length of the magnetic tape including the unrecorded portion.

  When the external device control display unit 601 of the external device 101 is in the focus display position, if the “cursor button” of the remote controller 105 is instructed to move downward, the focus display position is moved to the position marker 604, and the current magnetic tape is displayed. The position can be changed. At this time, the electronic program guide control circuit 307 notifies the control circuit 308 that the reproduction start position has been changed. Then, the control circuit 308 issues a command for changing the reproduction position to the target external device 101 through the communication circuit 309, and controls the reproduction position of the magnetic tape of the external device 101. That is, the externally connected device 101 is caused to fast forward or rewind to the designated tape position. When the “OK” button on the remote controller 105 is pressed again, the focus display position can be returned from the position marker 604 to the original external device control display unit 601.

  Consider a case where the “return button” of the remote controller 105 is pressed while the external device control display unit 601 of the external device 101 is in the focus display position. In this case, the electronic program guide control circuit 307 notifies the control circuit 308 that the playback channel of the external device 101 has been selected. Then, the control circuit 308 issues a reproduction command to the target external device 101 through the communication circuit 309. At the same time, the video playback circuit 304 and the communication circuit 309 are controlled, and the video playback circuit 304 generates a playback video signal from the video information input from the communication circuit 309.

  The function to be used can be changed by pressing the “decision button” of the remote controller 105 while the external device control display unit 601 of the external device 101 is in the focus display position. These functions to be used are those for which the support function of the external device 101 is acquired in step S404 in FIG. 4 and the function determined to be usable in step S405 when the electronic program guide screen is created. .

  In the embodiment of the present invention, as shown in FIG. 8, the display state changes and the external device control display unit 601 is the same, but the time axis information becomes the character string “time” 606 that means the reproduction time, and the time axis Is displayed, the reproduction time display section 607 starting from the current time is the vertical axis. Furthermore, a reproduction reservation time display unit 608 is displayed which has a margin for reproduction time when the magnetic tape of the external device 101 is reproduced.

  When the external device control display unit 601 of the external device 101 is in the focus display position, when the “cursor button” is used to instruct the downward, the focus display position is moved to the reproduction reservation time display unit 608. In this state, the position of the reproduction reservation display unit 608 can be changed by pressing the “OK” button and instructing the up and down with the “cursor button”. When the “OK” button is pressed again, the focus display position can be moved from the reproduction reservation display unit 608 and returned to the original external device control display unit 601.

  In this state, when the time set in the playback reservation time display unit 608 comes, the control circuit 308 issues a playback command to the target external device 101 through the communication circuit 309. At the same time, the video playback circuit 304 and the communication circuit 309 are controlled, and the video playback circuit 304 generates a playback video signal from the video information input from the communication circuit 309 via the IEEE 1394 cable 102.

  Furthermore, with reference to FIG. 9, a function that can be used by pressing the “decision button” while the external device control display unit 601 of the external device 101 is in the focus display position will be described. FIG. 9A shows the display content of the external device 101 on the electronic program guide screen when the camera function of the digital video camera 101 which is an externally connected device is used. The time information is a character string “time” 701 indicating time, and a time display unit 702 is displayed on the vertical axis. In the camera function, a shooting interval, a shooting period, an output destination, and the like are designated, and a camera image is output to a designated output destination at a designated regular interval for a designated period.

  In (a) of FIG. 9, the camera video is designated to be displayed on the sub screen displayed on the display screen 104 of the digital television 103 for 10 seconds at intervals of 10 minutes. When the designated time comes, the electronic program guide control circuit 307 issues a display notification on the child screen of the video from the external device 101 to the control circuit 308, and the control circuit 308 controls the video playback circuit 304 and the communication circuit 309. Then, the video of the external device 101 is reproduced on the child screen of the display screen 104. In other words, the video of the external device 101 and the video of the broadcast channel are synthesized as a sub-screen image by the video signal synthesis circuit 305 so that the video of the external device 101 can be displayed in the sub-screen of the display screen 104. it can.

  In addition to this, by specifying a printer or the like in the IEEE network constructed via the communication circuit 309 as an output destination, it is possible to control a periodic image printing operation and the like.

  FIG. 9B shows the display contents of the external device 101 on the electronic program guide screen when the still image recording / playback function is used. The time information is a character string “reproduction time” 704 meaning reproduction time, and a reproduction time display unit 705 having a reproduction time of 1 hour and a scale of every 10 minutes as a guide is displayed on the vertical axis.

  The still image recording / playback function can use the slide show function, and the playback time is calculated and displayed from the number of still images recorded on the memory card composed of the semiconductor memory circuit and the display time per frame. . That is, when the “return button” is pressed in the state of FIG. 9B, a slide show notification is issued from the electronic program guide control circuit 307 to the control circuit 308. Then, the control circuit 308 issues a command for acquiring a still image recorded in the semiconductor storage memory of the external device 101 via the communication circuit 309 at a specified interval. Thus, the still image acquired via the IEEE 1394 cable 102 is converted into a video signal by the video reproduction circuit 304 via the communication circuit 309 and displayed on the display unit 306.

  When the function of the external device 101 to be used is changed from the electronic program guide screen as in the above method, the control circuit 308 receives the notification from the electronic program guide control circuit 307, and the external device 101 is connected via the communication circuit 309. Change to a state where the desired function can be used. As a result, the external device 101 can be intuitively operated from the electronic program guide screen, so that the function provided by the external device 101 can be handled as one of the broadcast programs.

<Embodiment 2>
Hereinafter, a second embodiment of the present invention will be introduced. A configuration diagram of a video equipment control apparatus suitable for use in this embodiment is the same as that shown in FIG. The flow of processing for generating an electronic program guide screen in this embodiment will be described with reference to the flowchart of FIG.

  Similar to the flowchart of FIG. 4, when display of the electronic program guide is instructed by the operation of the remote controller 105 by the user, the processing of generating the electronic program guide screen in step S1001 starts. After the start of the electronic program guide screen generation process, first, electronic program guide information is acquired through the broadcast receiving circuit 301 in step S1002. At this time, the electronic program guide information may be acquired through the broadcast receiving circuit 301, or the electronic program guide information acquired in advance by the broadcast receiving circuit 301 and stored in the electronic program guide control circuit 307 may be used. This is the same as Embodiment 1 in FIG.

  In step S1003, it is confirmed whether an external device is connected to the communication circuit 309. If no external device is connected via the IEEE 1394 cable 102, the process proceeds to step S1009, and an electronic program guide screen is generated in accordance with the electronic program guide information acquired in step S1002. However, if an external device is connected to the communication circuit 309 in step S1003, the process proceeds to step S1004, and the external device connected via the IEEE1394 cable 102 (in the case of FIG. 1, the digital video camera 101) supports it. To get the function. For example, it is checked using “SUBUNIT INFO status command” of the IEEE 1394 standard. In step S1005, all the functions that the digital television 103 can use among the functions of the external device 101 are checked. In step S1006, all available functions are acquired. In step S1007, all function items acquired in step S1006 are added to the electronic program guide. In step S1008, it is confirmed whether there is any other undetected externally connected device connected via the IEEE 1394 cable 102.

  If an unconfirmed externally connected device is detected, the process returns to step S1004 to acquire a function supported by the currently unconfirmed externally connected device. Thus, when all available functions possessed by all the externally connected devices 101 are acquired and items to be added to the electronic program guide are determined, the process proceeds to step S1009, and the electronic program guide control circuit 307 displays the electronic program guide screen. Generate.

  FIG. 11 is an example of an electronic program guide screen generated by the above processing. Basically, the electronic program guide for broadcasting is equivalent to the electronic program guide shown in FIG. However, in the electronic program guide of FIG. 11, items of the electronic program guide are added according to the acquisition of all available functions in step S1006. That is, a tape recording / playback function indicated by reference numerals 901 and 902, a camera function indicated by 903, a still picture recording / playback function indicated by 904, and the like are displayed on the electronic program guide screen of the display screen 104 with the external device 100 as one channel. At this time, if the item of the external device 101 is changed from “901” to “902” using the “select button” of the remote controller 105 (not shown), the time-axis character string “reproduction time” 905 and the time information display unit 906 correspond to each function. The display is switched. At the same time, the control circuit 308 receives a function selection notification from the electronic program guide control circuit 307 and issues a command for changing to a state in which a desired function of the external device 101 can be used via the communication circuit 309. Operations and operations in each function are the same as those in the first and second embodiments.
