The GUI display processing unit 12 interrupts and displays the output warning screen on the display unit 14. In the example of FIG. 4, a character “cannot be reserved” is displayed on the display unit 14.

  The procedure of the reservation information display process in the above hardware configuration will be described using a flowchart. 5 and 6 are flowcharts showing the procedure of the reservation information display process. The control unit 11 of the display device 1 determines whether or not a recording reservation start signal has been received from the input unit 13 (step S51). When it is determined that the recording reservation start signal is not received from the input unit 13 (NO in step S51), the control unit 11 waits until the recording reservation start signal is received. On the other hand, when the control unit 11 determines that a recording reservation start signal has been received from the input unit 13 (YES in step S51), the reservation information set on the display device 1 side is read from the television-side reservation information file 151 (step S52). ).

  The control unit 11 reads the reservation information set on the recording device 2 side from the recorder-side reservation information file 152 (step S53). The EPG acquisition unit 19 acquires the EPG (step S54), and outputs the acquired EPG to the control unit 11. The control unit 11 combines the reservation information on the display device 1 side read in step S52 with the EPG, adds an icon indicating the display device 1, and colors the color (step S55). Specifically, as shown in FIG. 3, the recording date / time and the channel in the reservation information are referred to, and a character indicating that the recording reservation is made on the display device 1 side in the EPG of the same channel in the same time zone. An icon indicating the display device 1 is added in the vicinity thereof. Further, the EPG of the same channel in the same time zone is colored in blue so that it can be distinguished from a background color such as white.

  The control unit 11 combines the reservation information on the recording device 2 side read in step S53 with the EPG, adds an icon indicating the recording device 2, and colors a color different from the color colored in step S55 (step S56). ). Specifically, as shown in FIG. 3, referring to the recording date and time and the channel in the reservation information, a character indicating that a recording reservation is made on the recording device 2 side in the EPG of the same channel in the same time zone. An icon indicating the recording device 2 is added in the vicinity thereof. Further, the EPG of the same channel in the same time zone is colored so that it can be distinguished from a background color such as white in yellow.

  The control unit 11 adds information indicating that the recording reservation is prohibited in the time zone overlapping with the date and time in the reservation information read in steps S52 and S53 to the EPG (step S57). Specifically, as shown in FIG. 3, the recording date and time and the channel in the reservation information are referred to, and characters indicating that the recording reservation is prohibited are added to the EPGs of different channels in the same time zone. The EPGs of different channels are colored red, which is different from the colors colored in steps S55 and S56, and different from the background color. The control unit 11 outputs the EPG on which the processes of steps S55 to S57 have been performed to the GUI display processing unit 12, and the GUI display processing unit 12 receives the EPG and displays the EPG on the display unit 14 (step S58).

  The control unit 11 receives reservation information from the input unit 13 (step S59). The controller 11 determines whether or not the reservation information received in step S59 overlaps the reservation information read in steps S52 and S53 (step S61). Specifically, it is determined whether the date / time information related to the read reservation information and the date / time information of the reservation information received from the input unit 13 overlap. When it is determined that the reservation information is duplicated (YES in step S61), the control unit 11 reads the warning screen stored in the storage unit 15 (step S62) and outputs it to the GUI display processing unit 12. The GUI display processing unit 12 interrupts and displays the output warning screen on the display unit 14 as shown in FIG. 4 (step S63). Then, the process returns to step S59 again.

  On the other hand, when the control unit 11 determines that the reservation information does not overlap (NO in step S61), the control unit 11 stores the received reservation information in the television-side reservation information file 151 (step S64). The control unit 11 refers to the date and time information output from the clock unit 18 and determines whether or not it is a predetermined time (for example, 30 seconds before) the reservation time related to the reservation information stored in the TV-side reservation information file 151. (Step S65). The predetermined time may be set to an appropriate value in consideration of the startup time of the recording device 2 and the like. If the control unit 11 determines that it is not a predetermined time before the reservation time (NO in step S65), it waits until the predetermined time is reached. On the other hand, if the control unit 11 determines that it is a predetermined time before the reservation time (YES in step S65), the control unit 11 reads the reservation information from the television-side reservation information file 151 (step S66). And the control part 11 transmits the read reservation information to the video recording apparatus 2 via the communication part 16 (step S67). The recording device 2 switches the channel of the tuner 27 based on the reservation information, and stores the video data in the recording / playback unit 272 when the reservation time is reached.

When inputting the reservation information on the recording device 2 side, the user switches the input of the display device 1 to the recording device 2 side through the input unit 13. A recording reservation start button is operated from the input unit 23 of the recording apparatus 2. When the control unit 21 receives a recording reservation start signal from the input unit 23, the EPG acquisition unit 29 acquires the EPG and outputs the acquired EPG to the control unit 21. The control unit 21 refers to the recorder side reservation information file 251 in the storage unit 25 and reads the stored reservation information.

  The control unit 21 combines the reservation information with the date and time information related to the read reservation information and the EPG on the channel. In the example of FIG. 7, it is shown that there is a recording reservation in channel 2 from 5 pm to 7 pm. The user operates the input unit 23, moves the cursor 121, selects a desired time zone and channel, and operates a decision button (not shown). Here, the reservation information input from the input unit 23 is received by the control unit 21. The control unit 21 transmits reservation information to the display device 1 via the communication unit 26.

  The control unit 11 of the display device 1 reads the reservation information from the television-side reservation information file 151 and the recorder-side reservation information file 152, and determines whether it overlaps with the received reservation information. If there is no overlap, the control unit 11 stores the reservation information transmitted to the recorder-side reservation information file 152. In addition, the control unit 11 transmits a signal indicating that the reservation is permitted to the recording device 2. The control unit 21 of the recording device 2 stores the reservation information received from the input unit 23 in the recorder-side reservation information file 251 triggered by reception of a signal indicating that the reservation is permitted.

  FIG. 8 is an explanatory view showing a display image of a warning screen on the recording apparatus 2 side. Here, when the user makes a recording reservation for news broadcast on the channel 1 from 3:00 pm to 4:00 pm, it overlaps with the reservation information on the display device 1 side. When the transmitted reservation information overlaps, the control unit 11 of the display device 1 reads the warning screen stored in the storage unit 15 and outputs it to the GUI display processing unit 12. The GUI display processing unit 12 interrupts and displays the warning screen on the display unit 14 as shown in FIG. Thereby, even when a reservation is made from the recording apparatus 2 side, duplication can be prevented in advance.

  9, FIG. 10 and FIG. 11 are flowcharts showing the procedure of the recording reservation process according to the second embodiment. The control unit 11 of the display device 1 receives an input switching signal from the input unit 13 to the recording device 2 side, and when receiving this, switches the input to the recording device 2 side (step S91). When starting the recording reservation, the user operates a recording reservation start button from the input unit 23 of the recording apparatus 2. The control unit 21 on the recording device 2 side determines whether or not a recording reservation start signal resulting from the recording reservation start button of the input unit 23 has been received from the input unit 23 (step S92). When the recording reservation start signal is not received (NO in step S92), the control unit 21 waits until the start signal is received. On the other hand, when the control unit 21 determines that a recording reservation start signal has been received from the input unit 23 (YES in step S92), the EPG acquisition unit 29 acquires an EPG from the data stream (step S93). The acquired EPG is output to the control unit 21.

  The control unit 21 refers to the recorder-side reservation information file 251 in the storage unit 25 and reads the stored reservation information (step S94). The control unit 21 synthesizes the reservation information with the date and time information related to the read reservation information and the EPG on the channel (step S95). The control unit 21 outputs the EPG to the communication unit 26 via the GUI display processing unit 22. The communication unit 26 transmits the EPG to the display device 1 (step S96). The control unit 11 of the display device 1 receives the EPG and displays the EPG on the display unit 14 as shown in FIG. 7 (step S97).

  The control unit 21 of the recording device 2 receives reservation information from the input unit 23 (step S98). The control unit 21 determines whether or not the received reservation information overlaps the reservation information stored in the recorder-side reservation information file 251 (step S99). If the control unit 21 determines that there is an overlap (YES in step S99), the warning screen stored in advance in the storage unit 25 is read, and the read warning screen is combined with the EPG (step S910). The control unit 21 transmits the EPG combined with the warning screen to the display device 1 (step S911). The control unit 11 of the display device 1 receives the EPG combined with the warning screen and displays it on the display unit 14 (step S912). Note that after step S911, the control unit 21 returns the process to step S98.

  On the other hand, when it is determined that the reservation information received by the control unit 21 does not overlap with the read reservation information (NO in step S99), the received reservation information is transmitted to the display device 1 (step S101). This reservation information is transmitted as CEC information between the communication unit 26 and the communication unit 16. The control unit 11 of the display device 1 receives the transmitted reservation information (step S102). The control unit 11 of the display device 1 reads reservation information from the television-side reservation information file 151 (step S103). Further, the control unit 11 reads the reservation information from the recorder-side reservation information file 152 (step S104). The control unit 11 determines whether the reservation information received in step S102 overlaps with the reservation information read in steps S103 and S104 (step S105).

  If the control unit 11 determines that there is an overlap (YES in step S105), the control unit 11 reads the warning screen stored in the storage unit 15 (step S106). Then, the read warning screen is output to the GUI display processing unit 12. The GUI display processing unit 12 interrupts and displays a warning screen as shown in FIG. 8 on the EPG displayed on the display unit 14 (step S107). In addition, after the process of step S107, the control part 21 returns a process to step S98 again. On the other hand, if the control unit 11 determines that there is no duplication (NO in step S105), the reservation information received in step S102 is stored in the recorder-side reservation information file 152 on the display device 1 side (step S108). In addition, the control unit 11 transmits a signal indicating that the reservation is permitted to the recording device 2 (step S109).

  Note that a signal indicating that the reservation is permitted may be transmitted as CEC information between the communication unit 16 and the communication unit 26. The control unit 21 of the recording device 2 receives a signal indicating that the reservation is permitted (step S1010). The control unit 21 stores the reservation information received from the input unit 23 in step S98 in the recorder-side reservation information file 251 (step S1011). This makes it possible to avoid duplication with reservation information already registered on the display device 1 side when making a recording reservation from the recording device 2 side.
