The input transport stream is supplied to the digital interface 36, subjected to interface processing, and then supplied to the multiplexer / demultiplexer 41. Further, the transport stream supplied from the multiplexer / demultiplexer 41 is supplied to the digital input / output terminal 35 and supplied to the external device via the IEEE1394 serial bus.

In the above embodiment, the video data and the audio data are encoded according to the MPEG standard and then recorded in the hard disk drive 43. To do the processing,
The data may be recorded without performing the encoding process. Furthermore, instead of the hard disk drive 43, a recording medium such as an optical disk, a magneto-optical disk, or an individual memory may be used.

Next, the operation of the hard disk recorder 10 will be described. When a program to be recorded in the hard disk recorder 10 is reserved, the EPG information is used to individually specify the program to be reserved. Alternatively, a desired genre or keyword is set, and a program related to the set genre or keyword is automatically reserved. For example, by setting any of "news", "sports", "drama", "variety", etc. as the genre of the program, or by specifying a keyword such as "soccer", "golf", etc. You can make reservations for all news programs and golf programs related to keywords without having to make individual reservations.

When the recording status of the program is to be grasped, the video data of the recording situation monitor image which makes it easy to visually grasp the recording situation of the program is converted into the on-screen signal generating section 53.
And is superimposed on the video data supplied from the post video signal processing unit 52.

In this recording status monitor image, a display showing recorded programs is displayed on a time range display having a time range from the present time to a predetermined time before as a display range, and a time position is aligned within the time range display. It is something to display.

FIG. 2 is a diagram showing a display screen when a recording status monitor image is displayed. Recording status monitor image GA
Indicates, for example, a horizontally long bar display, and the right end portion indicates the position at the current time t0 and the left end portion indicates the position corresponding to the time tb 12 hours before the current time t0. . Here, when the recording start time of the individually reserved program is before the current time t0 by the time TW1 and TW2, the bar display is changed to another recording time from positions H1 and H2 corresponding to the recording start time. It is assumed that the display is different from that of the portion, for example, the display shows individually reserved programs in different colors. When the automatically reserved program is recorded before the time TW3 before the current time t0, the bar display is changed from the position H3 corresponding to the recording start time to the recording time by the recording time. A different color is used to indicate the program automatically reserved.

Further, as described above, the recording status monitor image GA has a display range in the time range from the current time to a predetermined time before, so that the programs displayed in accordance with the passage of time. Move the position of to the left.
As will be described later, when cache data is recorded, the cache program is displayed for the time TWca of the program cached to the left from the current time t0.

By the way, when the recording status of a program is displayed by the bar display, it is not possible to determine what program is recorded simply by displaying the bar display differently from other portions. . Therefore, the control unit 61
Controls the on-screen signal generator 53 to display the program selection cursor Ka on the bar display. Further, when the display indicating the program is selected by the program selection cursor Ka, the information regarding the program of the selected display is read from the hard disk drive 43 and supplied to the on-screen signal generation unit 53, so that the screen is displayed. The video data for displaying the program content information GB, for example, the title of the program is generated and superposed on the video data supplied from the post video signal processing unit 52.

As described above, by displaying the recording status monitor image GA, the recording status of the program, that is, the recording start time and recording time of the program can be visually and easily grasped. Further, since the display showing the program is switched depending on the difference in the reservation method, it is possible to comprehend the recording status of the individually reserved program or the automatically reserved program. Further, by moving the program selection cursor Ka for each program and selecting the display indicating the program, the program content information GB of the program corresponding to the selected display is displayed. It's easy to see if it's a different program.

Further, the display time position cursor Kb indicating which time the video data supplied from the post video signal processing unit 52 is the video is displayed by being displayed in association with the recording status monitor image GA. It is possible to easily determine which program the displayed video is.

Further, by providing the operation mode display GC indicating the operation mode of the hard disk recorder 10, whether the displayed image is the image of the program being selected or the program being recorded or the program being reproduced is displayed. It is possible to easily determine whether the image is a video.

Next, the display operation of the recording status monitor image will be described in relation to the operation of the remote control device 70 which supplies a remote control signal to the operation input unit 63, for example. FIG. 3 shows the configuration of the remote control device 70. Note that, in FIG. 3, the number and arrangement of the operation keys and the like are mere examples and are not restrictive.

Here, in the case of the standard reproduction speed, the bar display is moved leftward with the lapse of time, so that the display time position cursor Kb becomes a fixed position on the screen. However, when the fast-forward key 71-FF is operated, the reproduction speed is higher than the standard reproduction speed, so that the display time position cursor Kb is moved to the right according to the reproduction speed, as shown in FIG. 7C. When the fast-return key 71-FR for moving the reproduction position of the program in the reverse time direction at high speed is operated, the program corresponding to the display "P3" is reproduced in the reverse time direction at high speed. Therefore, as shown in FIG. 7D, the display time position cursor Kb is moved leftward according to the reproduction speed.

As described above, by moving the program selection cursor Ka and the display time position cursor Kb in association with the recording status monitor image GA, not only the recording status of the program can be easily confirmed, but also the contents of the recorded program. It is also possible to easily check and confirm the playback position.

The recording status monitor image GA and the like are not displayed only when the recording status monitor image display key 74 is operated. For example, when the operation of the hard disk recorder 10 is started or the reproducing operation is performed. If it is automatically displayed at the start or end of, or when the reproduction speed is changed, it is possible to easily confirm what kind of program reproduction state is in operation switching. Further, by ending the display of the recording status monitor image GA or the like after a preset time has elapsed, it is possible to prevent the recording status monitor image GA or the like from obstructing viewing of the program.

Further, in the above-mentioned embodiment, the case of recording the broadcast program from the broadcasting station has been described, but the same processing is performed also in the case of recording the distributed program from the head end like a cable television. Thus, the recording status of the program can be easily confirmed. It should be noted that the display positions and display contents of the respective displays shown in FIG. 2 and the operation key arrangement and the number of keys of the remote control device shown in FIG. 3 are mere examples and are not limited.

According to the present invention, the time range display showing the time range from the current time to the predetermined time before is displayed, and the display showing the recorded program is aligned with the time position within this time range display. The recorded program can be easily confirmed.

Further, since the display showing the recorded programs is switched according to the reservation method, it is possible to easily discriminate between the individually reserved programs and the programs which are automatically reserved and recorded.

Further, from the display showing the recorded programs, a program selection cursor for selecting the display of one of the programs is displayed, and the program content information regarding the program of the display selected by the program selection cursor is displayed. Therefore, it is possible to easily understand what kind of program is recorded.

Further, since the display time position cursor indicating the time position of the program to be output is displayed in relation to the time range display, it is possible to easily grasp at which time the displayed program is a program. . In addition, since the cache program is displayed by adjusting the time position within the time range display, the cache status of the program can be easily confirmed.
