  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a block diagram showing a video recording / reproducing apparatus 1 with a broadcast receiving function. The input unit 10 is provided with a terrestrial analog tuner 11. Of course, the input unit 10 may be provided with a digital TV receiving unit, a cable TV receiving unit, an external terminal for an IEEE1394 interface, and the like. The audio A / D converter 12 converts an analog video / audio signal from the terrestrial analog tuner 11 or the like into a digital signal. The NTSC decoder 13 converts an analog video signal from the terrestrial analog tuner 11 or the like into a digital signal (CCIR-REC 656).

  The MPEG video encoder 14 executes processing according to the MPEG video standard on the digital video signal output from the NTSC decoder 13. The MPEG audio encoder 15 executes processing according to the audio standard (MPEG / AC3 / linear PCM) on the digital audio signal output from the decoder 12.

  The multiplexer 16 multiplexes the video PES (Packetize Elementary Stream) output from the MPEG video encoder 14 and the audio PES output from the MPEG audio encoder 15 to output an MPEG stream. The buffer 17 temporarily stores the MPEG stream.

  The recording unit 20 is provided with a hard disk drive (HDD) 21 and a DVD recorder 22. The hard disk stores content such as received video. This content can be dubbed onto the DVD disc of the DVD recorder 22. In the DVD recorder 22, the MPEG stream (digital signal) is modulated by a modulation unit (not shown) so as to be easily recorded on the DVD medium, and a pickup (not shown) records the data on the DVD medium by irradiating a laser beam based on the modulation signal. . The pickup reads a signal from the DVD medium and converts it into an electric signal. The electric signal output from the pickup is converted into a digital signal by the demodulator.

  The demultiplexer 31 of the output unit 30 separates the MPEG stream (the video, audio, and subtitles are one signal while having the respective identifiers) into the video stream and the audio stream according to the identifier. The separated data is temporarily stored in the video buffer 32 and the audio buffer 33.

  The MPEG video decoder 34 decodes the video stream to obtain quantization coefficients and motion vectors, and outputs video data by performing inverse DCT transformation, motion compensation control based on the motion vectors, and the like.

  The MPEG audio decoder 35 decodes audio code data (code data in a format such as Dolby AC-3) in the audio stream to generate uncompressed audio data. The audio D / A converter 36 D / A converts uncompressed audio data.

  The OSD circuit 37 synthesizes the image created on its own side with the video data output from the MPEG video decoder 34 and / or the video data output from the NTSC decoder 13 in the input unit 10. That is, the OSD circuit 37 outputs video data based on character information and color information instructed to be output from a system controller (not shown) to an adder (for example, a drawing memory) (not shown). The adder performs processing for incorporating the video data into the video data output from the decoders 34 and 13. The OSD circuit 37 can display an EPG (Electronic Program Guide) screen, a user name input screen, a viewed setting screen, a deletion confirmation screen, and the like. The switch S selects and outputs the audio from the MPEG audio decoder 35 or the audio from the audio A / D converter 12.

  The NTSC encoder 38 encodes the video data (color difference signal data) output from the OSD circuit 37 into an NTSC signal. An image based on the NTSC signal is displayed on the monitor 39.

  Each of these circuits is controlled by a system controller (not shown). In addition, as shown below, this system controller creates various input screens (OSD display), records management of information input on the screen, records management of viewing status for each user for each title (recorded program), Performs viewing completion determination of each title, message display processing, and the like.

(1) User Name Registration Screen and User Name Registration FIG. 2 shows a user name registration screen. In the example of FIG. 2, up to six users can be registered, and a state where three people are registered at the present time is shown. Character input representing a user is performed by using a soft keyboard (displaying a keyboard on the screen and specifying a character by a direction key operation and a determination operation of the remote controller) or by causing a numeric key of the remote controller to function as a character key. be able to. After inputting the user name, the user presses the enter key. The system controller records the input user name in a nonvolatile memory (not shown). For example, when the enter key is pressed without inputting the user name in the “user 3” field, the user name can be registered as “user 3” by default.

(2) Scheduled Viewing User Designation Screen and Registration of Viewing Scheduled User FIG. 3 shows a viewing scheduled user designation screen. The example shown in FIG. 3 shows a state in which two users (AAA, BBB) among the three users (AAA, BBB, CCC) are scheduled to view the title XX. The viewing-scheduled user designation screen may be displayed when the program recording is completed, or may be displayed when recording or recording reservation. You may enable it to designate on what time point to display on a user menu screen. Of course, the screen may be displayed when a predetermined operation for calling the viewing-scheduled user designation screen is performed. When the system controller detects the up / down key operation of the remote controller, the cursor (color change area) is moved up and down on the right side column (check mark column) of the user name. The user presses the enter key when the cursor is placed next to the viewing target user name. When the system controller detects that the enter key has been pressed, the system controller determines that the user at the cursor position is the scheduled viewing user, and records the user in a non-illustrated nonvolatile memory in association with the title OO.

(3) Viewing Status Input Screen for Each User and Viewing Status Registration FIG. 4 shows a viewing status input screen for each user regarding the title OO. The system controller generates the screen shown in FIG. 4 by reading out the scheduled viewing user (AAA, BBB in the above example) associated with the title OO from the nonvolatile memory. Instead of displaying only the scheduled viewing users, all registered users may be displayed, and other users than the scheduled viewing users may be displayed in a dark state, for example, and the check input described later may not be performed (skip). In response to the question “Do you want to be viewed” displayed on the screen, a user who has played and viewed all of the title adds a check mark to his / her user name. When detecting the up / down key operation of the remote controller, the system controller moves the cursor (color change area) up and down on the horizontal column (check mark column) of the user name. The user presses the enter key when the cursor is on the user name portion. When the system controller detects that the enter key has been pressed, the system controller determines that the user at the cursor position is a viewed user, adds a check mark, and associates the viewed user with the title XX in the nonvolatile memory. Record in memory. In addition, a user identification screen (user name or password input screen before playback, user name input screen after playback) for specifying the user before or after playback of the title is displayed, and all titles are displayed. When the user is reproduced, the user specified on the user specifying screen may be authenticated as a viewed user. With such a configuration, the device automatically recognizes viewing for each user without the user performing a button operation to indicate viewing.

(4) Title Deletion Confirmation Screen FIG. 5 shows a screen asking for permission to delete the title XX. The system controller displays this title deletion confirmation screen when it is determined that all viewing target users regarding the title XX have been viewed. On the title deletion confirmation screen, a soft key labeled “YES” and a soft key labeled “NO” are displayed. The user selects any key. When detecting the left / right key operation of the remote controller, the system controller alternately displays a cursor (color change area) on one of the keys. When the system controller detects that the YES key has been pressed, the system controller performs processing to delete the title OO. The deletion process is not limited to deleting the partial TS that is the data itself of the title XX, but it is sufficient to delete information about the recording location. When the NO key is selected, for example, when the power is turned on next time, the screen shown in FIG. 5 is displayed on the first display screen to prompt deletion again.

  In addition, you may make it record the recording of a user who is scheduled to view or who has already been viewed as metadata (title name, data such as recording time) of title (video content). Further, resume information for each user (information indicating how far the data has been reproduced and information enabling reproduction from the reproduction end point at the next reproduction) may be recorded in the metadata. In order to manage the viewing status for each user, for example, when recording resume information for each user as described above in the metadata, a user specifying screen for specifying the user at the time of playback of the title OO or after playback is displayed. Good. The user can be specified by prompting the user to input a user name or a password for each user. By recording resume information for each user, it is possible to automatically determine the viewing status for each user. When it is determined that all users have finished viewing the title XX, the title can be automatically deleted.

  A remote controller (not shown) is provided with a color button. Therefore, the color of the color button may be associated with the user who is scheduled to view. Then, when the user recognizes that the device has been viewed with the screen of FIG. 4 displayed, the user presses the color button of his / her own color. The system controller that has detected the pressing of the color button can recognize that the user corresponding to the color has been viewed.
