The video signal recording / reproducing apparatus shown in FIG.
As shown in FIG. 3, the system controller 19 is provided, and the driver 21 is controlled according to the recording / reproducing / simultaneous recording / reproducing mode designated by the user through the user interface 20, and the recording position and the reproducing position of the recording / reproducing head 10 are controlled. To control. Further, the system controller 19 controls the post-processor 15 in accordance with various display modes of the two-screen split / playback screen / recording monitor screen designated by the user via the user interface 20 during simultaneous recording / playback to control the display state. Switch. Further, the system controller 19 controls the OSD 18 to read an icon or a message for identifying the mode according to the display mode from a memory (not shown) and supply it to the addition circuit.

Next, the operation of the system controller 19 controlling the post processor 15 to switch the display on the display according to the user's operation will be described with reference to FIGS. 2 and 3 to 7.

First, the system controller 19 starts recording by detecting that the user has instructed recording via the user interface or that the time reserved in advance has been reached.

In step 51, the system controller controls the post-processor 15 to display the video signal supplied from the pre-processor 5 in full screen as a recording monitor screen as shown in FIG. Further, the system controller 19 controls the OSD 18 to display the icon 31 indicating that the display screen is the monitor screen of the video signal being recorded in the right corner of the screen. This icon is controlled so as to automatically disappear when a predetermined time has elapsed from the start of recording. The display may be continued until an operation is performed by the user or the display mode is switched.

In step 52, the system controller 19 checks whether there is no recording end instruction via the user interface or whether the reserved recording end time has been reached. If the recording should be ended, the recording is ended and the standby mode is entered. Otherwise, in step 53, the system controller 19
Checks for playback instructions via the user interface.

In step 53, when the reproduction of the desired recorded or recorded program is selected by the user's operation, the reproduction of the program is started.
Here, since the recording is not completed, the recording and the reproduction are simultaneously performed. Proceeding to step 54, the system controller 19 controls the post processor 15 to make a full screen display of the playback screen as shown in FIG. At this time, the system controller 19 controls the OSD 18 to display the icon 33 indicating recording and the icon 32 indicating reproduction in parallel at the right corner of the screen.

Here, after the start of recording and before the end of recording, the reproduction of the program being recorded from the beginning or before the current recording position is called chasing reproduction. When the reproduction speed is faster than 1 × speed, the difference between the reproduction position and the recording position becomes small little by little, and it will eventually catch up. When the reproduction speed is 1 ×, the difference between the reproduction position and the recording position is always the same, and the recording ends first.

During follow-up reproduction, the system controller 19 controls the driver 21 so as to alternately move the recording position and the reproduction position. The head 10 can record and reproduce data at a transfer rate sufficiently higher than the bit rate of the video signal. When a predetermined amount of recording data is accumulated in a buffer (not shown), the data is collectively recorded on the medium, and the data in the buffer which is reproduced and stored in advance is read out little by little. Further, when the amount of data in the buffer which has been reproduced in advance becomes small, the system controller 19 controls the driver 21 to move the head 10 to the reproduction position, and temporarily stores the reproduced data in the buffer.
The encoded data to be recorded, which is input during that time, is stored in the buffer. By repeating such an operation, recording and reproduction can be performed simultaneously without interruption.

In step 55, the system controller 19 checks whether the recording monitor button or the return button is operated via the user interface. When the recording monitor button is operated, the process proceeds to step 56 and the post processor 1
5, the recording monitor screen and the reproduction screen are divided and displayed as shown in FIG. At this time, the display screen on the reproduction side is controlled to be slightly larger than the screen of the recording monitor. At this time, the image frame on the selected reproduction screen side may be further emphasized.

Further, at the time of split display of two screens, the system controller 19 controls the OSD 18 to display an icon 34 indicating reproduction and a icon 35 indicating recording so that the recording monitor screen and the reproduction screen can be distinguished from each other. Display near the screen. Further, the current time 36 of the reproduction position and the current time 37 of the recording position are displayed respectively.

In step 57, the system controller 19 checks whether the recording monitor button or the return button has been operated via the user interface. When the recording monitor button is operated, the process proceeds to step 58 and the post processor 1
5, the recording monitor screen and the reproduction screen are displayed separately. At this time, the screen of the recording monitor is controlled to be slightly larger than the display screen on the reproducing side.
At this time, the image frame on the selected recording monitor screen side may be further emphasized.

When the recording monitor screen is enlarged, the system controller 19 controls only the recording side to be effective for various operations by the user.
Therefore, in this state, the recording can be stopped or paused, but the stop operation on the reproduction side, the pause, the slow, the reproduction speed changing operation for the high speed reproduction, and the like cannot be performed. On the contrary, when the reproduction screen is large, the system controller 19 controls so that only the reproduction is effective for various operations by the user.
Therefore, in this state, the reproduction can be stopped, paused, slowed, and the reproduction speed changed operation for the high-speed reproduction can be performed, but the recording side stop operation and the pause operation cannot be performed.

In step 59, the system controller 19 checks whether the recording monitor button or the return button has been operated via the user interface. When the recording monitor button or the return button is operated, the process returns to step 54,
The system controller 19 controls the post processor 15 to make a full screen display of the playback screen shown in FIG.

As described above, the split screen display of the recording monitor (large) and the playback screen (small), the split screen display of the recording monitor (small) and the playback screen (large), and the movement between the playback screen displays are performed. It is possible to sequentially move in one direction by performing a single operation on a recording monitor button which is a single operator provided on the remote controller.

Further, in steps S55, S57,
In step S59, by operating the return button, it is possible to return to the display of the reproduction full screen at any time from any display state.

Next, with reference to FIG. 9, a modification of the operation in which the system controller 19 controls the post processor 15 to switch the display on the display (not shown) will be described below.

The system controller 19 starts recording by detecting that the user has instructed recording via the user interface or that the time reserved in advance has been reached.

In step 1, the system controller controls the post-processor 15 to display the video signal supplied from the pre-processor 5 in full screen as a recording monitor screen as shown in FIG. Further, the system controller 19 controls the OSD 18 to display the icon 31 indicating that the display screen is the monitor screen of the video signal being recorded in the right corner of the screen. This icon is controlled so as to automatically disappear when a predetermined time has elapsed from the start of recording. The display may be continued until an operation is performed by the user or the display mode is switched.

In step 2, the system controller 19 checks whether there is no recording end instruction through the user interface or whether the reserved recording end time has been reached. If the recording should be ended, the recording is ended and the standby mode is entered. If not, in step 3, it is checked whether there is a playback instruction via the user interface.

When the chase reproduction is instructed in step 3, in step 4, the system controller 1
Reference numeral 9 controls the post processor 15 to display the recording monitor screen and the reproduction screen as shown in FIG. At this time, the display screen on the reproduction side is controlled to be slightly larger than the screen of the recording monitor.

When the two screens are displayed separately, the system controller 19 controls the OSD 18 to display the icons 32 and 33 so that the recording monitor screen and the reproduction screen can be identified.

When the reproduction screen is large, the system controller 19 controls so that only the reproduction side is effective for various operations by the user. Therefore, in this state, stop operation on the playback side, pause,
You can perform operations such as slow speed and high speed playback, but you cannot stop or pause recording.

In step 5, the system controller 19 checks whether the recording monitor is selected via the user interface. When the recording monitor is selected, in step 6, the system controller 19 controls the post processor 15 so that the display screen on the recording side becomes larger than the display screen on the reproducing side as shown in FIG.

When the recording screen is large, the system controller 19 controls only the recording side to be effective for various operations by the user. Therefore, in this state, the recording side stop operation and the pause operation can be performed, but the reproduction stop and pause operations and the reproduction speed change operation cannot be accepted.

In step 7, the system controller 19 checks whether the recording monitor is selected via the user interface. When the recording monitor is selected, in step 8, the system controller 19 controls the post processor 15 to display the recording monitor screen in full as shown in FIG. On the other hand, if the recording monitor is not selected, proceed to step 10,
In the system controller 19, it is checked whether the reproduction screen is selected via the user interface.

When the full-screen display of the recording monitor or the playback screen is changed from the split display of two screens, the system controller 19 controls the OSD 18 to display an icon in the right corner for a predetermined time to display the current display screen. Inform the user of the corresponding mode. That is, when the split screen display of two screens is changed to the full display of the recording monitor screen, the system controller 19 controls the OSD 18 to display the icon indicating that the reproduction is being performed and the icon indicating the recording monitor screen rightward for a certain period of time. The icons are displayed in parallel in the corners, and the icon indicating the recording monitor screen is highlighted. On the other hand, when the split screen display is changed to the full playback screen display, the system controller 19
Controls the OSD 18 to display an icon indicating that it is being reproduced and an icon indicating that it is a recording monitor screen side by side in the right corner for a certain period of time, and emphasizes the icon indicating that it is a reproduction screen. .

When the system controller 19 detects in step 10 that the reproduction screen is selected through the user interface, step 4 is executed.
Returning to step 5, the system controller 19 controls the post processor 15 to divide and display the recording monitor screen and the reproduction screen so that the reproduction screen is slightly larger than the screen of the recording monitor as shown in FIG.

In step 9, it is checked whether the playback screen is selected via the user interface. When the playback screen is selected, the process returns to step 6, and the system controller 19 controls the post processor 15 so that the recording monitor screen and the playback screen are slightly larger than the playback screen as shown in FIG. Split display.

When the recording monitor side is not selected in step 5, the process proceeds to step 11 and the system controller 19 checks whether or not the reproduction screen is selected via the user interface. When the reproducing side is selected, in step 12, the system controller 19 controls the post processor 15 to make a full display of the reproducing screen as shown in FIG. Further, the system controller 19 controls the OSD 18 to emphasize and display the icon 32 indicating the reproduction screen. On the other hand, if the playback screen is not selected, step 5
Return to.

In step 13, the system controller 19 checks whether the recording monitor screen is selected via the user interface. When the recording monitor screen is selected, the process returns to step 4, and the system controller 19 controls the post processor 15 to divide and display the recording monitor screen and the reproduction screen so that the reproduction screen is slightly larger than the recording monitor screen.

The above-described recording full screen display, recording monitor (large) and playback screen (small) split screen display, recording monitor (small) and playback screen (large) split screen display, and movement between playback screen displays Can be moved sequentially in either direction by operating the direction indicating operator provided on the remote controller to the left or right. Further, operators for recording display and reproduction display may be provided in pairs.
Further, here, the operation when the reproduction is instructed during the recording operation is described, but when only the reproduction operation of the recorded program is performed, the display screen is the full screen of the reproduction screen as shown in FIG. It is displayed. Then, under the control of the system controller 19, the OSD 18 displays the icon 38 indicating the reproduction state in the left corner of the screen. Here, when recording is instructed, step S5 in FIG.
8 or step S6 in FIG. 9, and the same operation as described above is performed.

Next, referring to FIGS. 8 and 10 to 14, the system controller 19 controls the post processor 15 to automatically switch the display on the display (not shown) during the simultaneous recording / reproduction. The operation will be described below.

If the full screen display of the reproduction screen is being performed in the mode in which the recording and the reproduction are being performed at the same time (for example, the chasing reproduction mode), in step 21,
The system controller 19 checks whether the recording is stopped by the user or when the reservation end time is reached.

When the recording is completed, the routine proceeds to step 22, where it is judged whether the recording monitor screen and the reproduction screen are divided display screens. In case of split display screen, go to step 23,
The system controller 19 controls the post processor 15 to keep the recording monitor screen as the screen supplied from the preprocessor 5, that is, the television screen as shown in FIG. 10, and controls the OSD 18 to perform recording. The icon that indicates is erased. At this time, the currently displayed channel number 6 may be displayed as shown in FIG. On the other hand, if it is not the split display, step 2
In step 4, the system controller 19 controls the post processor 15 to display the television screen (recording monitor screen) in full and controls the OSD 18 to turn off the icon indicating that recording is in progress. Here, instead of deleting the icon, an icon 61 indicating the displayed channel number may be displayed as shown in FIG.

When it is determined in step 21 that the recording has not ended, the process proceeds to step 25, and the system controller 19 checks whether or not the stop of the reproduction is instructed through the user interface by the operation of the user. When the reproduction is stopped by the user's operation, the system controller 19 determines in step 26 whether the recording monitor screen and the reproduction screen are split display screens. In the case of the split display screen, the process proceeds to step 27, where the system controller 19 controls the post processor 15 to set the playback screen to the still screen and the playback pause mode and to control the OSD 18 as shown in FIG. Then, the icon 34 indicating that the reproduction is being performed on the reproduction screen side is changed to the icon 62 indicating the pause. On the other hand, if it is not the split display, the process proceeds to step 28, where the system controller 19 controls the post processor 15 to set the playback screen to the still screen and the playback pause mode and controls the OSD 18 as shown in FIG. Then, the icon 32 indicating that it is being reproduced is changed to the icon 63 indicating pause.

If in step 25 it is determined that the playback has not been stopped by the user, then step 2
Proceed to 9. In step 29, the system controller 19 determines whether or not the reproduction position has caught up with the recording position by the chasing reproduction. When it is determined that the reproduction has stopped due to catching up, in step 30, it is determined whether the recording monitor screen and the reproduction screen are split display screens. In the case of the split screen display, the process proceeds to step 31 and the system controller 19 controls the post processor 15 to execute the process shown in FIG.
As shown in, the reproduction screen is changed to the black screen or the blue screen, and the OSD 18 is controlled to erase the icon 34 indicating that the reproduction is being performed. On the other hand, when it is not the split screen display, the process proceeds to step 32 and the system controller 19
Controls the post processor 15 to display the recording monitor screen in full as shown in FIG. 3 and erases the icon being reproduced to display the icon indicating recording. At this time, the system controller 19 may control the OSD 18 to display that the recording monitor screen is displayed or that the reproduction has caught up.

If it is determined in step 29 that the reproduction has not stopped due to catch-up, step 2
Return to 1.
