And an FF button 25.

The FF button 25 of the remote control unit 2 is used to change the reproduction speed of the reproduced image displayed on the display unit 3 of the television device 1 with a built-in memory. For example, when the FF button 25 is continuously pressed, the reproduction speed of the reproduced image becomes high, and when the FF button 25 is released, the reproduction speed becomes a predetermined reproduction speed. The leave selection switch 24 is operated by pressing "ON" when the user leaves the seat and "OFF" when returning to the seat. Or, this leaving selection switch 24 is
A toggle switch type may be used in which “ON” and “OFF” are repeated each time the button is pressed. In addition, L of the remote control unit 2
The CD panel section 21 can display various control information and the same content as the display content of the display section 3 of the television device 1 with a built-in memory according to a predetermined instruction.

Further, a display example of the display unit of the present invention will be described with reference to FIG. FIG. 3 is a picture-and-picture format two-screen display example shown as an example. At present, when a normal broadcast is being displayed on the display unit of the horizontally long screen, which is becoming the mainstream, when the "OFF" switch is pressed to indicate that the user is returning, the display unit is split into left and right. On the left screen L, the normal broadcast currently being broadcast is displayed as it is, and on the right screen R, the reproduced image, reproduced sound, and reproduced data called from the large-capacity memory of the television device 1 with a built-in memory are displayed. The state is displayed retroactively. It should be noted that the reproduction speed of the reproduced image, reproduced sound, and reproduced data can be specified by the user to an arbitrary reproduction speed.

As another display function, the system controller 10 of the television apparatus 1 with a built-in memory stores the size of the small screen previously selected by the user and the reproduction speed, and the size of the previously selected small screen is displayed. A picture-in-picture display with a so-called learning function, which is displayed on the display unit at the reproduction speed selected last time, is also possible. Further, "leaving mode" indicating that the leaving mode is selected is displayed in the margin of the display unit, and "high-speed playback" indicating high-speed playback is displayed in the playback screen of the right screen R or not shown. It is possible to display "20 times reproduction" indicating the reproduction speed.

Similarly, the operation of the television with a built-in memory according to the present invention in the away mode will be described with reference to the flow chart of FIG. The user has a built-in memory television device 1
During reception, the remote control unit 2 or the like is operated to select and start the away mode (step SP1). Step S
At P2, the user selects the leaving selection switch which is "ON" when leaving the seat and "OFF" when returning to the seat. At this time, for example, when the user selects “ON”, the “separation mode” is displayed on the display unit 3 of the television device 1 with built-in memory as shown in FIG. 3E from the fixed data of the ROM / RAM 13 shown in FIG. Display and move to step SP3. If "OFF" is selected, move to playback loop of step SP5. However, when the user selects the leaving selection mode in advance by another means, that is prioritized, and the television device with a built-in memory 1 records by the FIFO (first-in first-out) operation up to the limit of the recording capacity of the large capacity memory. And prepare for the playback operation.

At step SP3, the system controller 10 shown in FIG.
Generate and register. In step SP4, the image and audio data together with the recording ID are compressed in the large-capacity memory of the television device 1 with a built-in memory and recording is started. With such an operation, a recording loop is formed in which the recording is repeated by the FIFO operation up to the limit of the recording capacity of the large capacity memory held by the television apparatus 1.

Next, the operation during reproduction will be described. When the user returns to the seat and activates the leave selection switch “OFF”, the reproduction loop is started. In step SP5, I of the image / audio data recorded with the record ID in the large capacity memory
Search for and read D. Further, in step SP6, the recorded contents are read from the large capacity memory and displayed on the display unit 3 of the television device 1 with the built-in memory. At this time, the user can operate the reproduction speed of the recorded contents. For example, if the FF button 25 of FIG. 2 is operated, the reproduction speed can be changed freely. When the reproduction speed is not designated by the user, the reproduction is performed at a predetermined reproduction speed, and the high-speed reproduction operation is continued until catching up with the normal broadcast in the current broadcast. Step S
In P7, the reproduced image will be replaced by normal broadcast,
A small screen of picture-in-picture, or two screens of picture-and-picture or multi-screen is displayed. At this time, the display unit 3 displays "High-speed playback in progress" as shown in FIG. 3F.

At step SP8, the remaining amount of the reproduction time is verified (compared) with the data at the time of recording in the large capacity memory.
After processing, the user does not reach the departure point specified by the user (N
In the case of O), the large-capacity memory is activated and the image is reproduced at high speed by going back to the user's leaving start point. When the leaving start point designated by the user is reached (YES), the process proceeds to step SP9. In step SP9, when all the reproduction operations are completed, the original normal broadcasting is resumed, and the operation in the recording / reproduction mode for a series of away seats is completed.

In the above embodiment, the case where the user gives instructions to leave and return to the seat has been described. However, there is a case where the recording is automatically always performed and the user simply gives an instruction to return to the seat for a certain period of time. Alternatively, the presence or absence of the user may be automatically detected by using various sensors. For example, it is possible to instruct “said” by voice recognition or the like. Further, although in the above-described embodiment, the image data processing is mainly described, strictly speaking, MPEG2 level digital data is separated into image data and audio data and recorded in a large capacity memory. Further, the present invention can be applied not only to image data and audio data but also to data information. Needless to say, the present invention can be developed into various forms without being limited to the embodiment described above.
