  The recorder 1 having the above-described configuration obtains video information from the outside and records it on the HDD 17 or DVD (recording process), and copies (duplicates) information recorded on the HDD 17 to the DVD (copy process). Can be executed independently. In addition, the television receiver 2 having the above-described configuration can independently execute processing (video / audio output processing) for acquiring video and audio information from a television broadcasting station or an external device, and performing video display or audio output. It has become.

  Further, in a state where both devices are connected, that is, as the video processing system 9, processing (recording / playback processing) for playing back video and audio information recorded in the recorder 1 on the television receiver 2 can be executed. The video processing system 9 also performs processing (hereinafter referred to as “copying” for convenience) that causes the television receiver 2 to execute a predetermined operation (such as an operation for notifying the user of the completion of copying) when the copying process is completed in the recorder 1. This is referred to as “completion notification process”. Note that the copy completion notification process is executed using CEC of the HDMI standard, as will be described later.

  Next, the content of the copy completion notification process will be described below with reference to the flowchart shown in FIG.

  The recorder 1 (calculation control unit 14) monitors whether or not a copy execution instruction has been given by the user in a normal state (step S11). When the execution instruction (predetermined operation in the operation unit 16) is made (Y in step S11), the recorder 1 is instructed to copy video information or the like (video and audio information recorded in the HDD 17). The process of copying the range information to the DVD is started (step S12).

  Thereafter, when the copy process is completed (Y in step S13), the recorder 1 determines whether the copy completion notification flag is “ON” (step S14). The “copy completion notification flag” is information recorded in the memory 15 and is set to either “ON” or “OFF” in advance. Further, the state of the “copy completion notification flag” can be updated as appropriate in accordance with a user instruction.

  If the copy completion notification flag is “ON” (Y in step S14), the recorder 1 transmits predetermined notification information to the television receiver 2 (step S15). Then, after transmitting the notification information or when the copy completion notification flag is “OFF” (N in Step S14), the recorder 1 repeats the process in Step S11.

  The notification information is for causing the television receiver 2 to execute a predetermined operation (OSD display display, input switching, etc.). Note that the specific contents of the operation will be apparent from the following description.

The above-described notification information transmission uses HDMI standard CEC, and the notification information uses a Vendor Specific Command (vendor command) of the HDMI standard. The contents of the vendor command can be arbitrarily defined by the device manufacturer. Here, for reference, an example of a communication format by CEC is shown in Tables 1 and 2.

  The first byte represents the communication direction. For example, “0x10” represents communication from the recorder (logical address: 1) to the television receiver (logical address: 0). The second byte indicates whether the subsequent information is a vendor's unique code. For example, “0x89” indicates that it is a unique code.

  In the third byte, “0x10” represents “notification”, and “0x11” represents “inquiry (acquisition request)”. If the third byte is “0x10”, the fourth byte represents the state of the device on the transmission side, the fifth byte represents the number of characters of the message to be notified, and the sixth and subsequent bytes represent the character code of the message. Are represented in order. According to CEC, when an Active Source command, which is a basic command, is received from a transmission-side device, input to the transmission-side device is switched in the reception-side device.

  On the other hand, the television receiver 2 (calculation control unit 31) monitors reception of notification information from the recorder 1 (step S21). When the notification information is received (Y in step S21), the arithmetic control unit 31 superimposes a predetermined OSD display on the video signal through the control of the OSD / scaler circuit 27c. Thereby, the OSD display is displayed on the panel of the PDP module 28 (step S22).

  The OSD display includes, for example, a message for notifying the user that the copy process is completed and a message for asking whether or not input switching is necessary, as shown in FIG. As a result, the user can immediately know that the copying process has been completed. Data for realizing the OSD display (message contents, etc.) may be included in the notification information (sent from the recorder 1 side), or may be registered in the television receiver 2 in advance. good.

  When the notification information is received while the television receiver 2 is in the standby mode (so-called “power OFF” state set when not in use), the normal mode (so-called set when in use, so-called “power off”) is automatically set. It is possible to switch to the “power ON” state and display the OSD display described above.

  Further, in the state in which the OSD display is displayed, the user can select whether to perform input switching execution / non-execution (selection of “YES” or “NO” shown in FIG. 5) through the operation on the operation unit 33. ) Is possible (step S23). Here, “input switching” refers to a process of setting the HDMI terminal 22 to be effective through the control of the switch 27a when the HDMI terminal 22 to which the recorder 1 is connected is not set to be effective.

  If YES is selected, that is, if an instruction to perform input switching is given by the user (Y in step S23), the television receiver 2 executes input switching (step S24). Thus, for example, even if the television receiver 2 receives a television broadcast while the copy process is being performed on the recorder 1 side (even if the broadcast signal input terminal 23 is set to be valid), the HDMI terminal 22 Is enabled.

  Therefore, the user can display the duplicated video on the television receiver 2 simply by playing the DVD given to the recorder 1, and can confirm whether the duplication has been executed correctly. In addition, after the input is switched or when non-execution of the input switching is selected (N in Step S23), the television receiver 2 repeats the process in Step S21.

  Note that the mode of the copy completion notification process is not limited to that described above, and various modifications can be made. For example, in the television receiver 2, only one of the process of displaying the OSD display (step S22) and the process of switching input (steps S23 and S24) may be performed. Further, when the notification information is received without receiving the input switching execution instruction by the user (without executing the process of step S23), the input switching (step S24) is automatically executed. You may do it.

  Further, when input switching (step S24) is executed in the television receiver 2, the fact is notified to the recorder 1, and the video duplicated by the current copy process is automatically played back (DVD). Playback may be executed). As a result, the user can more easily confirm whether the duplication has been correctly executed.

  As described above, in the video processing system 9 according to the present embodiment, the recorder 1 has a function of recording video information acquired by broadcast reception or the like in the HDD 17 (first storage medium) and a video recorded in the HDD 17. It has a function of writing information on a DVD (second storage medium) given to the DVD drive 18 and copying it, and a function of generating a control signal based on HDMI standard CEC and transmitting it to the television receiver 2.

  Also, the recorder 1 generates a notification signal (a type of control signal) for executing a copy completion notification process when the duplication operation is completed, and transmits the notification signal to the television receiver 2. The notification signal is a control signal (setting instruction signal) for causing the television receiver 2 to perform input switching, and a control signal (display instruction signal) for causing the television receiver 2 to display a predetermined OSD display. It can be said that there is.

  Therefore, the user can immediately know that the duplication process has been completed through the display on the television receiver 2, and further confirm whether the duplication has been correctly executed (display the contents of the DVD on the television receiver 2). Is possible). Further, since the established CEC is used for communication between the recorder 1 and the television receiver 2, it is not necessary to provide a new communication standard, and highly reliable communication can be easily realized. Yes.

  As mentioned above, although an example of the embodiment of the present invention was explained, the present invention is not limited to these contents. As the embodiment, various modifications can be made without departing from the gist of the present invention.

  The present invention can be used in a video processing system that processes video.
