FIG. 8 is a diagram showing an example of a reproduction recommendation icon display in the broadcast recording apparatus according to the embodiment. FIG. 9 is a diagram illustrating an example of a reproduction recommendation list display in the broadcast recording apparatus according to the embodiment.

(Overview)
The playback title recommendation function is to display a list of playback recommendation titles from recorded titles in consideration of the user's preference appearing in the operation history of the reservation processing / playback processing, so that the user can easily find a program of interest. It is a function that can.

(Operation)
First, in the flowchart of FIG. 2, the recording tendency of the title selected at the time of the reserved recording and the title selected by the user by the operation of the reserved recording unit / preference detection unit / reproduction recommendation unit 42 of FIG. From the reproduction tendency, a preference database is generated (step S11).

  Specifically, as shown in FIG. 3, the recording tendency of the title selected at the time of reserved recording and the title selected to be reproduced by the user by the functions of the reserved recording unit / preference detection unit / reproduction recommendation unit 42. As shown in FIG. 3, for example, 3 points are given to the word, “music”, etc. used in the recording reservation (or the reproduction process) as shown in FIG. Similarly, as shown in FIG. 4, for example, 20 points are given to a word for identifying a genre used in recording reservation (or playback processing), “Japanese music”, and the like. That is, as a user's operation information, a point database is added to the word or genre from the detailed contents of the title and the title, thereby generating a preference database that means what the user wants. In addition, although reservation recording was demonstrated to the example, not only reservation recording but the title at the time of recording the program which is airing now by remote control operation etc. is also made into a database as a sample of preference.

  Next, if the recommended display mode is selected by the user via the operation unit 32 or the like (step S12), the title recommendation level is calculated by the functions of the reserved recording unit, the preference detection unit, and the playback recommendation unit 42. .

  In other words, by the operation of the reservation recording unit, the preference detection unit, and the playback recommendation unit 42, a plurality of titles currently stored in the hard disk drive unit 18 and the like are determined based on the above-described preference database. The recommendation level is calculated (step S13). For example, as shown in FIG. 5, one title has information such as title ID, title name, detailed contents, genre, recording time, program time, total viewing time, and the like.

  Here, an example of a method for calculating the recommendation level of each title will be described with reference to FIG. In FIG. 6, the recommendation point is initialized to “0” in the operation of the preference detection unit / reproduction recommendation unit 42 (step S11). Then, the playback degree calculation is started (step S12). The calculation of the degree of playback performed by the function of the preference detection unit 42 is that the denominator is the shorter of “program broadcast time (on EPG)” and “actual recording time”, and the numerator is “total viewing time” of the title. It is expressed as a percentage. For example, if a 60-minute program is recorded for 90 minutes for the baseball extension function and the total viewing time of the title is 30 minutes so far, the playback rate is 30 minutes / 60 minutes, so the rating is 50%. It becomes.

  Next, if it is determined that the playback degree is a certain level (for example, 40%) or more (step S13), the recommended point of the title information given by the reserved recording or the like is calculated. That is, genre preference points are acquired from the genre database and added as recommended points (step S14). Further, only one word is extracted from the title name (step S15), and it is determined whether there is a word registration in the preference database (step S16). If it exists, the number of points is acquired from the preference database as 3 points, for example (step S17), and the word points are added as recommended points (step S18). This process is repeated until the end of the title name is reached (step S19). Also, the program contents are also added in the same way as the title name, and the recommended points of the title are set as No. 1 in FIG. As shown in FIG. 10, for example, 100 points are calculated (step S20).

  On the other hand, as shown in the flowchart of FIG. That is, in the function of the preference detection unit / reproduction recommendation unit 42, the recommended point is initialized as “0” (step S31), and the reproduction degree calculation is started (step S32). The calculation of the degree of playback performed by the function of the preference detection unit 42 is that the denominator is the shorter of “program broadcast time (on EPG)” and “actual recording time”, and the numerator is “total viewing time” of the title. It is expressed as a percentage. For example, if a program with 60 minutes scheduled to be broadcast is recorded for 90 minutes for the baseball extension function, and the total viewing time of the title so far is 30 minutes, the playback rate is 30 minutes / 60 minutes, so the rating is 50%. It becomes. Next, if it is determined that the degree of reproduction is a certain value (for example, 40%) or more (step S33), the recommended point is determined as the degree of reproduction (step S34).

・ Recommended title display method Finally, the recommended title display method, but various methods are possible as described below. That is, according to the recommendation level of each title obtained in this way, for example, a title that does not reach this value is hidden or a title having a recommendation level equal to or higher than this value is compared with a predetermined recommendation level. The order is changed and displayed according to the height of the degree (step S14).

  As an example, in the thumbnail list of FIG. 8, a playback recommendation (recommendation) holder H1, a frequently-viewed title holder H2 and the like are displayed. The titles T1 to T6 arranged in order of the recommendation degree are displayed.

In this display method, the following various modifications are possible.
That is, contrary to the above case, it is also preferable to recommend only titles with a low playback level (eg, less than 10%). By doing so, it is possible to efficiently view what is left by the user.

  It is also preferable to display titles with a certain playback level or higher in descending order of playback level, that is, to display frequently viewed titles on the entire surface.

  It is also preferable to limit the titles to be recommended to titles for which automatic deletion is set. In this way, it is possible to positively give viewing opportunities to titles that are deleted.

Further, the recommendation may be performed in consideration of the last access time (the elapsed time since the last operation for the title such as recording, reproduction, and editing). That is, since the last access time is long, there is a risk that it will be forgotten, and by displaying it preferentially, reproduction is recommended so that the user will not miss it.

It is also preferable to calculate any of the above recommendation levels and create a program list in descending order of the recommendation levels.
Here, when recommending a part of a series, it is preferable to recommend a series that has not yet been viewed as one title (series).
It is also preferable to recommend the title of the first episode for a series that has not yet been seen.

  In addition, it is also preferable to recommend a title with the next number of stories in a series that has been viewed halfway.

  It is also preferable to perform processing in consideration of the concept of series as a recommended point calculation or recommended title.

In addition, as a title recommendation display format,
As shown in FIG. 8, when icons H1 and H2 such as folders are selected, it is preferable to display a reproduction recommendation list as shown in FIG.
In addition, it is preferable to recommend reproduction of a title based on a different standard for each icon by displaying a plurality of icons H1 and H2 such as folders as shown in FIG. Thereby, for example, title lists of various standards can be displayed such as icon H1 (recommended title) and icon H2 (simply viewed title).

  Also, as shown in FIG. 9, it is preferable to display a list of titles in order of recommendation degree.

  Also, it is preferable that titles that do not satisfy the recommendation conditions are not displayed in the list (displayed in a narrowed down manner).

  Further, as shown in FIGS. 8 and 9, it is preferable to inform the user of the degree of recommendation by expressing the recommendation degree of the title by the number of symbols such as stars and crowns.

  In addition, it is preferable to start playback of titles by the operation of the control unit 30 or the like by selecting these titles from the playback recommendation list of FIG.

  The various embodiments described above enable those skilled in the art to realize the present invention. However, it is easy for those skilled in the art to come up with various modifications of these embodiments, and have the inventive ability. It can be applied to various embodiments at least.
