Description

  The present invention relates to a recording / playback apparatus that records a broadcast program and plays back the recorded program, and more particularly to a recording / playback apparatus that allows a user to easily record and play back a continuous program.

  Some programs, such as TV broadcasts, are broadcast on a one-off basis, but for example, like a drama, animation, quiz program, variety program, etc., for example, for half a year or a year or more (or a certain number of times) Many of them are broadcast regularly at the same time. In addition, like a special program such as a sports broadcast such as a XX cup, a program with similar or related contents may be broadcast over a certain period of time even if the contents of each broadcast are complete. Such programs are often produced so that the contents of the broadcasts are linked together to form a story, or when the contents of the previous broadcast are known, the contents of the current broadcast can be enjoyed further. A program that is broadcast a plurality of times and has continuity in a broad sense in the broadcast content is hereinafter referred to as a “continuous program”.

  When a user views a program with continuity as described above, it is usual to use a recording / playback device or the like so as not to miss the broadcast as much as possible. Therefore, for the convenience of the user, there has been proposed a recording / playback apparatus capable of automatically recording each broadcast for a continuous program. In order to perform such automatic recording, information related to a broadcast time zone and a channel of a program may be acquired by using various program information (EPG or the like) transmitted by being superimposed on a broadcast wave.

  For example, in the program recording reservation device described in Patent Document 1, a continuous program is extracted from program information scheduled to be broadcast, recording is reserved, editing recording is performed to link these programs, or It is equipped with functions such as connecting and playing back continuous programs by recording information that can determine whether the program is continuous or not in the information that manages the recorded program. .

  In addition, a continuous program group is identified from programs recorded and stored in the recording / playback apparatus using the program title name as a key, and the list is displayed as one recording unit or played back. There has been proposed a recording / playback apparatus that can be used.

For example, the recording / playback apparatus described in Patent Document 2 includes a title extraction unit that extracts title names of recorded programs, and the same extracted title names are grouped together into different title names. A function for displaying only the titles as a title list, a function for continuously playing a program group of the same title, and the like are installed.

In these drawings, the same reference numerals denote the same components, and the basic configuration and operation are the same. To do.

First Embodiment Hereinafter, a first embodiment of the recording / playback apparatus of the present invention will be described.
FIG. 1 is a diagram schematically showing an internal configuration of a recording / playback apparatus according to the present embodiment. In FIG. 1, a recording / reproducing apparatus receives a broadcast wave, selects a channel, reproduces a program, and records a program recorded by the program recording unit 11 as well as a program recording unit 11 that records the program as necessary. A recording file storage unit 13 composed of a recording medium and the like, and a recorded program reproduction unit 12 that reproduces a program recorded by the program recording unit 11 and stored in the recording file storage unit 13.

  FIG. 2 is a diagram showing a data structure of a recording file recorded by the program recording unit 11 and stored in the recording file storage unit 13 in the recording / playback apparatus shown in FIG. As shown in FIG. 2 (b), a recording file 20 created by a conventional recording / playback apparatus is composed of a header information part and a recording data body part. Program information 21 is included. On the other hand, as shown in FIG. 2 (a), the recorded file 22 in the present embodiment is a program in which the recording data body is continuous in addition to the recorded program information 21 as in the past in the header information section. In some cases, it has fields for storing link information 23 to the previous recording file and link information 24 to the next recording file of the recording data body. Note that when the recorded data body is not a continuous program or when it is the first or last program of a continuous program, the initial value NULL is described in the fields 23 and 24.

  By adopting such a data structure for the recording file, for example, when an operation such as recording a continuous program as a continuation of the previous time is performed, the recording file is inserted between the previous recording file and the current recording file. Link information can be described mutually.

  FIG. 3 is a functional block diagram showing in detail the configuration of the program recording unit 11 in the recording / playback apparatus shown in FIG. In FIG. 3, the program recording unit 11 includes a program receiving / reproducing unit 31, a reserved recording setting unit 32, a recording unit 33, and a link information updating unit 34.

  The program reception / reproduction unit 31 includes a tuner, a demodulator, a decoder, a video / audio signal processing unit, and the like, and generates a reproduction signal of a program selected from the received broadcast wave. The reproduction signal is output to a display device (not shown) and the recording unit 33. In addition, the program receiving / reproducing unit 31 decodes the program information included in the broadcast wave, and outputs it to the reserved recording setting unit 32 and other necessary processing units (not shown).

  When the scheduled recording setting unit 32 receives a scheduled recording request for a specific program, the scheduled recording setting unit 32, based on program information acquired from the program receiving / reproducing unit 31 or another processing unit (not shown), a predetermined date and time, channel, etc. Then, the scheduled recording information for recording the program is generated. Thereafter, when the set scheduled recording time arrives, the scheduled recording setting unit 32 outputs a recording instruction to the recording unit 33 according to the scheduled recording information.

  In the recording / playback apparatus according to the present embodiment, while the user is watching a continuous program, an operation for pre-recording the next broadcast of the program can be performed (for example, by pressing a dedicated button). When this operation is performed, the scheduled recording setting unit 32 sets the scheduled recording by acquiring the next broadcast time zone or channel of the program from the program information. In addition, while the continuous program stored in the recording file storage unit 13 is being played back by the recorded program playback unit 12, an operation for pre-recording the next broadcast of the program can be performed. In this case, the scheduled recording request including the program information of the program currently being reproduced by the recorded program reproducing unit 12 is output to the reserved recording setting unit 32 of the program recording unit 11, and the reserved recording setting unit 32 Performs the same scheduled recording process as above. Note that the scheduled recording setting unit 32 accepts and processes not only the scheduled recording request as described above but also a scheduled recording request (not limited to a continuous program) in which the user designates an arbitrary time zone and channel. Shall be possible.

  Further, when the program is recorded as a continuation of the previous broadcast according to the reserved recording setting, the scheduled recording setting unit 32 updates the link information so as to update the header information of the recording file for the previous broadcast and the recording file for the current broadcast. The header information update request is output to the unit 34. The link information update unit 34 accesses the recording file storage unit 13 according to the header information update request from the scheduled recording setting unit 32 and updates the link information to the next recording file in the header information of the recording file for the previous broadcast. At the same time, it requests the recording unit 33 to include link information to the previous recording file in the header information of the recording file for the current broadcast.

  FIG. 4 shows a link information update unit of the recording / reproducing apparatus when the continuous program is continuously recorded over a plurality of broadcasts (hereinafter referred to as “continuous recording”) in the recording / reproducing apparatus of the present embodiment. 34 is a flowchart showing the flow of processing for updating the header information of the recording file of the program according to 34. In FIG. 4, when the link information update unit 34 accepts a request for continuous recording for a certain program (step S41), the link information update unit 34 accesses the recording file storage unit 13 to link information to the next recording file among the recording files of the program. Search for a recording file whose is NULL (step S42). The link information update unit 34 requests the recording file storage unit 13 to include link information to the recording file to be recorded following the link information to the next recording file of the searched recording file (step S43). The recording unit 33 is requested to include the link information to the searched recording file in the link information to the previous recording file of the recorded file to be recorded (step S44).

  It should be noted that the update of the header information of the recording file accompanying the continuous recording may be performed when the scheduled recording information is determined or when the scheduled recording is completed. In the flowchart shown in FIG. 4, the process in step S43 and the process in step S44 may be executed in the reverse order. That is, after updating the header information of the recording file to be recorded for reservation, the header information of the previous recording file of the recording file may be updated.

  FIG. 5 is a diagram illustrating a mode in which the header information of the recording file is updated when continuous recording is performed. FIG. 5A shows a recording file A that is recorded first. The recording file A is in a state where there is no link information (NULL) for both the link information to the previous recording file and the link information to the next recording file. FIG. 5B shows a recording file A and a recording file B as a state after continuous recording is performed for the program. The recording file A and the recording file B are linked to each other. FIG. 5C shows a recording file A, a recording file B, and a recording file C as states after further recording for the program. The recording file B and the recording file C are linked to each other. In this way, it is recorded that the recording file A, the recording file B, and the recording file C are the recording files of the same continuous program and should be reproduced in the order of the recording files A, B, and C. It is like that.

Second Embodiment Hereinafter, a second embodiment of the recording / playback apparatus of the present invention will be described.
The recording / playback apparatus according to this embodiment has the same internal configuration as that shown in FIG. 1, that is, a program recording unit 11, a recorded program playback unit 12, and a recorded file storage unit 13. The program recording unit 11 and the recording file storage unit 13 are configured in the same manner as in the first embodiment.

  FIG. 6 is a functional block diagram showing in detail the internal configuration of the recorded program playback unit 12 of the recording / playback apparatus according to the present embodiment. In FIG. 6, a recorded program playback unit 12 creates a list of recorded programs stored in the recorded file storage unit 13 and presents a program list to the user, and a recorded program designated by the user. A playback unit 62 for playback, a resume information read / write unit 63 for accessing playback start position information of a recorded program, and a link information check unit 64 for checking link information included in a recording file of a recorded program specified by the user Yes.

  In the recording / playback apparatus of the present embodiment, in order for the recorded program playback unit 12 to play back the recorded program recorded in the recording file storage unit 13, it is first recorded in the recorded file storage unit 13 by the program list creation unit 61. A list of recorded programs is created and displayed on the screen. The processing flow by the program list creation unit 61 will be described with reference to the flowchart shown in FIG.

  In FIG. 7, the program list creation unit 61 first obtains a list of all recorded files recorded in the recorded file storage unit 13 (step S71). Thereafter, the recording files are read one by one from the recording file list (step S72), and it is checked whether there is link information to the previous recording file by referring to the header information of the read recording file (step S73). . Here, there is link information to the previous recording file for the recording file of the continuous program, but there is no link information to the previous recording file for the recording file of the program that is not the continuous program. . For a recording file without link information to the previous recording file, the recording file is displayed on the program list screen as it is (step S74). For the recording file with the link information to the previous recording file, the display in step S74 is not performed.

  Thereafter, it is determined whether there is a recording file that has not been read out in the recording file list acquired at step S71 (step S75). If there is a recording file that has not been read out yet, the process returns to step S72, and the next The recording file is read and the same processing as described above is performed. If all the recorded files have been read in step S75, the recorded program list creation process ends.

  As a result of the above processing, each recorded file is displayed in the recorded program list for a program that is not a continuous program. On the other hand, for a continuous program, the previous recording of a plurality of recorded files is performed. Since there is no link information to the file, that is, only the recorded file for the earliest broadcast is displayed in the recorded program list, each broadcast of the same program is not displayed separately, and the user It is possible to display a list of recorded programs that are easy to see for the user. Of course, the same effect can be obtained even if it is determined in step S73 whether there is link information to the next recording file, rather than whether there is link information to the previous recording file.

  Next, a procedure for reproducing a recorded program designated by the user on the display screen of the recorded program list in the recording / reproducing apparatus of the present embodiment will be described with reference to FIG. In FIG. 8, first, when the user selects a recorded program to be reproduced from the above-mentioned recorded program list (step S81), the resume information read / write unit 63 confirms whether the program has resume information (step S82). . Here, the resume information is information indicating to what extent (up to which point) the program has been played back when it was played back last time. In the recording / playback apparatus of this embodiment, for a continuous program, one resume information is created for all of a plurality of recording files constituting the series. When there is resume information in the program to be played back by the playback unit 62, the recording file specified in the resume information is opened (step S83), and when there is no resume information in the program to be played back Then, the recording file of the program is opened by a normal method (step S84). For a continuous program that has no resume information, the recording file of the earliest broadcast may be opened, or the latest recording file may be opened.

  Subsequently, the playback unit 62 analyzes the header information of the opened recording file (step S85), and starts playback of the recording file (step S86). When the reproduction is interrupted by a user operation or the like during the reproduction (step S87), resume information indicating how far the reproduction has been performed is created (step S811), and the reproduction is terminated. On the other hand, when playback to the end of the recording file has been completed (step S88), the header information of the recording file is referred to and it is determined whether or not the next recording file is specified in the “link information to the next recording file” field. If the next recording file is designated (step S810), the recording file is opened (step S89), and the processing after step S85 is executed again. If the next recording file is not specified in the “link information to the next recording file” field of the recording file that has been played back, the playback ends as it is. In this case, when the resume information exists in the reproduced recording file, the resume information is deleted or initialized. Thus, when the program is reproduced next time, the reproduction is started from the beginning of the program.

  As described above, when a continuous program recorded by the recording / playback apparatus of the present embodiment is played back, a recorded file that is being viewed is automatically selected without requiring any special operation by the user. Can be played.

  The above description is for the case where the recording file is normally played back. However, in the recording / playback apparatus of this embodiment, not only “link information to the next recording file” but also “previous recording file” is included in the header information of the recorded program file. "Link information to the recording file" is also included. For example, when rewinding playback (reverse playback) reaches the beginning of the recording file, it automatically starts rewinding from the end of the previous recording file. It is also possible to do so. For example, when the playback unit 62 reversely plays back the file B in FIG. 5C and reaches the top of the file, the playback unit 62 refers to the header information of the file B and determines that the previous file is the file A, and the file A The reverse playback can be continued from the end of.

  Similarly, if “link information to the next recording file” is used, when the end of the recording file is reached while the recording file is being played forward, the next recording file is automatically played from the beginning. You can enter. For example, the playback unit 62 performs a high-speed search in the forward direction during normal playback of the file B in FIG. 5C, and refers to the header information of the file B when the end of the file is reached. And the high-speed search in the forward direction from the beginning of file C can be continued.

  As described above, in the recording / playback apparatus according to the present embodiment, the continuity stored as a plurality of recorded files without requiring a special operation by the user regardless of whether the playback is normal playback or rewind playback. Can be continuously played back easily. In addition, using the “Link information to the next recording file” or “Link information to the previous recording file”, while playing the recorded continuous program, the previous broadcast or next broadcast It is also possible to skip. For example, if the operation of skipping the next broadcast of the program during the normal playback of the file B in FIG. 5C, the next recorded file is determined to be the file C with reference to the header information of the file B, Normal playback can be started from the beginning of file C.

Third Embodiment A third embodiment of the recording / playback apparatus according to the present invention will be described below.
The recording / playback apparatus according to this embodiment has the same internal configuration as that shown in FIG. 1, that is, a program recording unit 11, a recorded program playback unit 12, and a recorded file storage unit 13. The program recording unit 11 and the recorded file storage unit 13 are configured in the same manner as in the first embodiment, and the recorded program playback unit 12 is configured in the same manner as in the second embodiment. Shall.

  In the recording / playback apparatus of this embodiment, refer to the flowchart shown in FIG. 9 for the process of deleting the recording file of the continuous program using the link information of the recording file stored in the recording file storage unit 13. While explaining. It should be noted that the processing in each of the following steps is appropriately executed by a functional unit (not shown) that reads / writes from / to the recording file storage unit 13 of the recording / playback apparatus.

  In FIG. 9, first, the user selects a recorded program to be deleted on the recorded program list display screen (step S91). Here, when the user designates a continuous program, it is assumed that the user selects “delete all recorded files” or “delete some recorded files” for the program. In the case of “deleting a part of the recorded files”, it is further assumed that the recorded files of the program are displayed in a list and the user designates what is to be deleted.

  When the recording file to be deleted is determined, the first recording file is searched from among the recording files of the program (step S92). The head recording file can be searched by sequentially tracing “link information to the previous recording file” in the header information. Hereinafter, after reading one file at a time from the first recorded file (step S93), after reading the header information of the recorded file (step S94), it is determined whether the recorded file is a recording file to be deleted (step S94). S95). If the recording file is to be deleted, the recording file is deleted (step S96). In the recording file deletion process, not only the recording file is deleted, but also the link information included in the header information of the preceding and subsequent recording files is rewritten. That is, after the recording file is deleted, the header information is rewritten so that the previous recording file and the next recording file are linked as the preceding and following ones (however, the first recording file or For the last recorded file, “link information to previous or next recorded file” is set to NULL). On the other hand, if the read recording file is not a deletion target in step S94, the process proceeds to step S97.

  Subsequently, when “the link information to the next recording file” is included in the header information of the recording file read in step S94, the process returns to step S93, the next recording file is read, and the same processing as described above is repeated. On the other hand, if there is no “link information to the next recording file” in the header information of the recording file in step S97 (it is NULL), the recording file deletion process is terminated.

  Note that the recording file deletion of a program that is not a continuous program can also be deleted by the same procedure as described above.

  The recording / playback apparatus according to the present invention has been described with reference to specific embodiments, but the present invention is not limited to these.
