A scenario selection unit 25 for selecting a scenario most suitable for the viewer's taste based on the comparison result of 3, and a content attribute extraction unit for extracting and accumulating content attribute evaluation information associated with the content stored in the content storage medium 3. 27.

FIG. 6 is a diagram for explaining the structure of the multi-story content stored in the content storage medium 3. As shown in FIG. 6, the content storage medium 3 has content information 601 to 603 of a plurality of contents.
Is stored, and the content corresponding to the multi-story is divided into two or more sub-contents like the content A (601) and the content B (602).
For example, content A is composed of sub-contents A1, A2,
.., A6.

As shown in FIG. 6, a content field attribute for specifying a field to which the content belongs is assigned to each sub-content as content attribute evaluation information 620 to 628. For example, attribute evaluation information such as "action" is assigned as attribute evaluation information of the sub-content A1, and "SF" is assigned as attribute evaluation information of the sub-content A2.

Also, content scenario information 610 for determining the order of sub-contents reproduction for each scenario so as not to cause inconsistency in the scenario when reproducing the content.
613, and these pieces of information are also stored in the content storage medium 3. For example, for multi-story content A, there are three possible scenarios A-1, A-
Scenario A-1 is a sub-content sequence A1, A2, A5, scenario A-2 is a sub-content sequence A1, A2, A3, A5, and scenario A-3 is a sub-content sequence A1. , A3, A
4 respectively.

The viewing history storage device 9 stores a history of information on past viewing behaviors of the viewer until the next viewing. Here, it is assumed that, as viewing history information, the content field attributes of the viewed sub-contents are stored retroactively up to a predetermined maximum number.
In the present embodiment, as shown in FIG. 6, it is assumed that information specifying the reproduction order of sub-contents for each scenario is stored as content scenario information 610 to 613.

Next, the operation of the first embodiment will be described with reference to FIGS. 1, 6, and 7. First, the content reproduction control device 7 selects a desired content according to the operation of the viewer. If the selected content is a content that is not compatible with the multi-story, the attribute evaluation information of the selected content is acquired from the content storage medium 3, and the viewing history information of the viewing history storage device 9 is updated and stored.

When the content corresponding to the multi-story, for example, the content A in FIG. 6 is selected as the content desired by the viewer, the content reproduction control device 7
Attribute evaluation information of sub-contents A1 to A5 belonging to the selected content A and scenario A-1 to scenario A-3 available for content A, respectively, from content storage medium 3 via content storage medium control device 5 The scenario information 610 to 612 to be acquired is acquired.
Then, the content attribute extraction unit 27 extracts and accumulates attribute evaluation information of sub-contents for each scenario described in the content scenario information 610 to 612.

Further, the preference judging section 21 of the content reproduction control device 7 acquires the viewing history information so far from the viewing history storage device 9 and accumulates the viewing histories to determine the viewing preference. Next, the comparison unit 23 standardizes and expresses the attribute evaluation information accumulated by the content attribute extraction unit 27 and the viewing history accumulated by the preference judgment unit 21 as shown in FIG. Then, the absolute value of the difference between the two distributions is summed to calculate the difference between the scenario and the viewing history.

Then, the scenario having the smallest difference from the viewing history (scenario 3 in FIG. 7) is determined to be the scenario most suitable for the viewer's preference, and the scenario selecting unit 25
Notify. Finally, the scenario selection unit 25 sequentially reproduces the sub-contents according to the order specified in the scenario information corresponding to the scenario notified from the comparison unit 23, and reproduces the content of the selected scenario (story). The information is displayed on the reproduction monitor device 11.

The content reproduction control device 7 updates the contents of the viewing history storage device 9 by adding the viewing information of the sub-contents to the viewing history information every time the reproduction of the sub-contents ends.

According to the first embodiment described above, contents closer to the tastes of the viewer can be finely provided based on the daily viewing behavior of the viewer without requesting the viewer to make a special selection. be able to.

In this embodiment, the attribute evaluation information and the content scenario information are stored in the same content storage medium 3, but each information may be stored in a storage medium different from the content.

In this embodiment, only one field attribute is stored as the attribute evaluation information of the sub-content, but the field attribute to which one sub-content belongs is 1
Not necessarily one. For example, a plurality of field attributes for each sub-content and a weighting value of each field attribute are stored,
The weights may be taken into account when determining the scenario.

In the present embodiment, the field attribute is stored as the attribute evaluation information of the sub-content. However, the present invention is not limited to this, and may be any characteristic element.
It may be a characteristic element obtained by decomposing a field. For example, the field of science fiction also applies to other fields such as "science", "fantasy" and "future" (for example, "science" is a science field of education, "fantasy" is a field of other creative fields such as film). Elements may be classified and weighted. In this case, the viewing history information is weighted and accumulated for each element, and the data is correlated with the attribute evaluation information data of each scenario to determine the scenario.

In this embodiment, only the attribute evaluation information is stored and used for judging the viewer's preference. However, other information may be used at the same time. For example, the viewing time may be accumulated together with the attribute evaluation information of the viewed content, and the viewing history information may be weighted by the viewing time when calculating the preference information. Also, for example, a viewer who likes a long program may be provided with a long scenario, and a viewer who likes a short program may be provided with a shorter scenario in accordance with the viewing time. .

Further, in the present embodiment, as the content scenario information, a single order of reproducing the sub-contents constituting the scenario is stored. However, the present invention is not limited to this. For example, a part of the content may be added. As a special scenario, a plurality of pieces of this scenario information may be prepared for various fields.

In this embodiment, the scenario is selected by summing up the attributes of all the sub-contents of the scenario. However, the present invention is not limited to this. For example, the attribute evaluation is performed only for a predetermined part of the sub-contents. The information may be accumulated and used for the determination.

Furthermore, in the present embodiment, the method of selecting a scenario is not limited to the above method. For example, a method may be used in which, in descending order of the viewing frequency, sub-contents in which the weight of the field attribute is maximized as much as possible are selected according to scenario information within a range that does not contradict possible scenarios.

Next, a second embodiment will be described with reference to FIG. In the present embodiment, as the viewing history information stored in the viewing history storage device 9 in the first embodiment, the viewing history information analyzed for each content field is stored instead of the content field attribute. Here, when the viewing history information is updated, the weight of the viewing history information of the corresponding content up to immediately before is 1/2, and the weight of the current content is 1
The viewing history information for each attribute evaluation information is calculated as a total as / 2, and stored in the viewing history storage device 9. This is to feed back the current preference while reducing the weight of the past selection.

In the second embodiment, by storing information obtained by analyzing the viewing history, the capacity required for storing the viewing history information can be reduced.

In this embodiment, time-weighted viewing history information is used as viewing history information to be stored, but the present invention is not limited to this. For example, the viewing frequency for each piece of attribute evaluation information may be counted and accumulated. Further, the information to be stored is not limited to the attribute evaluation information itself. For example, the attribute evaluation information may be represented by an element applicable to another field, and the attribute evaluation information may be updated by a predetermined method according to the viewing behavior.

Also, in the present embodiment, the weight of the viewing history information up to immediately before and the weight of the currently viewed content are each set to １ ／, but the present invention is not limited to this.
For example, the weight of the attribute evaluation information up to immediately before may be 9/10, and the weight of the current content may be 1/10.

In this embodiment, the viewing history is stored for each content field attribute as viewing history information, but the present invention is not limited to this. For example, the content field attribute may be divided for each analyzed common element, and the viewing history may be stored for each common element. In this case, the content field attribute is appropriately weighted and expressed by each element, and when the viewing history is updated, each element is updated according to the weight.
