  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a schematic configuration of a recording / reproducing apparatus.

  The recording / reproducing apparatus includes an antenna 1, a tuner 2, a first external input terminal 3, a second external input terminal 4, an input switching unit 5, a video decoder / audio A / D unit 6, an MPEG encoder 7, a control unit 8, A large-capacity storage medium 9, a memory 10, an operation unit 11, an MPEG decoder 12, a video encoder / audio D / A unit 13 and an output terminal 14 are provided.

  External devices such as a BS / CS tuner, a DVD player, and a digital video camera are connected to the first external input terminal 3 and the second external input terminal 4. As the mass storage medium 9, a hard disk (HDD), DVD, or the like is used.

  At the time of recording, the input switching unit 5 selects either the television signal selected by the tuner 2 or the input signal from the external input terminals 3 and 4. The analog signal selected by the input switching unit 5 is digitized by the video decoder / audio A / D unit 6, encoded by the MPEG encoder 7, and then stored as a video / audio title in the mass storage medium 9.

  At the time of reproduction, the video / audio title stored in the large-capacity storage medium 9 is decoded by the MPEG decoder 12, converted to analog by the video encoder / audio D / A unit 13, and then output via the output terminal 14. The data is output to an external display device (such as a television device).

  The control unit 8 controls the MPEG encoder 7, the MPEG decoder 12, the large-capacity storage medium 9, the memory 10, and the like according to instructions from the operation unit 11.

  This recording / playback apparatus has a function of performing continuous recording, and also has a function of playing back a title being recorded constantly or a previously recorded title during continuous recording. Further, in this recording / reproducing apparatus, an operation for switching an input signal (in this example, input by the input switching unit 5) is performed when a title that is being recorded continuously or a title that has been previously recorded is being played back simultaneously with continuous recording. When the operation for switching the channel and the channel switching operation when the input signal from the tuner 2 is selected by the input switching unit 5 are performed, the input signal switching process corresponding to the operation is executed and the switching is performed. A function (small screen automatic display function) for displaying a subsequent received video (recorded video) on a small screen for a certain period of time is provided.

  For example, an operation when an operation for switching an input signal is performed when data recorded by continuous recording is reproduced from an address different from the recording address will be described.

  FIG. 2A shows a recording pointer (position M1) and a reproduction pointer (position P1) for an area where recording is always performed (always recording area). In the state of FIG. 2A, as shown in FIG. 3A, an image corresponding to the position P1 of the playback pointer is displayed on the monitor.

  Assume that an operation for switching the input signal is performed and the input signal is switched at the time shown in FIG. The playback pointer is at position P2, and the recording pointer is at position M2. In this case, as shown in FIG. 3B, a video corresponding to the position (P2) of the playback pointer is displayed on the monitor, and the video after input switching, that is, the position M2 of the recording pointer is displayed. The corresponding video is displayed on a small screen for a predetermined time (several seconds). In addition to the video after switching, this small screen displays the channel when the input video after switching is input from the tuner 2, and the input video after switching is from the first external input terminal 3. If it is an input, it is displayed that the input is external input 1, and if the input video after switching is an input from the second external input terminal 4, it is displayed that it is external input 2.

  Thereafter, when the state shown in FIG. 2C is reached, as shown in FIG. 3C, an image corresponding to the position P3 of the playback pointer is displayed on the monitor.

  FIG. 4 shows a processing procedure for realizing the small screen automatic display function.

  When a title being recorded at the same time as a regular recording or a previously recorded title is being played back (YES in step 1), if an operation for switching the input signal is performed (YES in step 2), the input An input signal switching process corresponding to the signal switching operation is performed (step 3).

  Also, the video currently being recorded (the input video after switching the input signal) is displayed on a small screen (step 4). At this time, in the small screen, in addition to the video currently being recorded, if the input video after switching is input from the tuner 2, the channel is displayed, and the input video after switching is the first external input terminal. When the input is from 3, the external input 1 is displayed, and when the input video after switching is the input from the second external input terminal 4, it is displayed as the external input 2. Then, after displaying the small screen in step 4, it is determined whether or not a predetermined time Ts has elapsed (step 5). For example, 5 seconds is set as the predetermined time Ts.

  If the predetermined time Ts has not elapsed, it is determined whether or not an operation for switching the input signal has been performed (step 7). If the operation for switching the input signal is not performed, the process returns to step 5. If an operation for switching the input signal is being performed, the small screen is erased (step 8), and then the process returns to step 3.

  If it is determined in step 5 that the predetermined time Ts has elapsed, the small screen is erased (step 6), and then the process returns to step 1.
