## Abstract

An information processing apparatus which presents a viewing schedule of a video content to a user is disclosed. The apparatus includes: a first acquiring means for acquiring a broadcast schedule of a broadcast content to be broadcast; a second acquiring means for acquiring information about a recorded content that has been recorded and an on-demand content that has been downloaded; a generating means for arranging the broadcast content, the recorded content, and the on-demand content on a same time axis as these contents are mixed, and generating the viewing schedule; and a display control means for displaying the generated viewing schedule.

## Claims

### Claim 1

An information processing apparatus which presents a viewing schedule of a video content to a user, the apparatus comprising:
at least one processor configured to:
acquire a broadcast schedule of a broadcast content to be broadcast;
acquire information about a recorded content that has been recorded and an on-demand content that has been downloaded;
collect user's viewing history;
compute, for each time frame on a particular day of a week from at least a subset of a plurality of time frames, a taste value comprising a plurality of dimensions indicating user's viewing behavior in previous instances of the respective time frame in the subset based on the collected user's viewing history, wherein at least one first dimension of the taste value is associated with the broadcast content and at least one second dimension of the taste value is associated with the recorded content;
compute, for broadcast content scheduled to be broadcast in respective time frames of the plurality of frames, for the recorded content and for the on-demand content, a respective evaluation value comprising a mathematical quantity indicating a feature of the broadcast content, the recorded content, and the on-demand content; and
generate the viewing schedule indicating, for at least one time frame of the plurality of time frames, proposed content selected from the broadcast content, the recorded content, and the on-demand content based on a degree of similarity between the taste value computed for the at least one time frame and the respective corresponding evaluation values computed for the broadcast content, the recorded content, and the on-demand content; and
display the generated viewing schedule so that the broadcast content, the recorded content, and the on-demand content are displayed on a same time axis;
wherein, the evaluation value computed for the broadcast content is computed for the time frame having a taste value that is equal to or greater than a threshold.

### Claim 2 (depends on 1)

The information processing apparatus according to claim 1, wherein the display device displays the generated viewing schedule in a two-dimensional matrix in which one of a vertical axis and a horizontal axis depicts a date, and the other depicts a time of day.

### Claim 3 (depends on 1)

The information processing apparatus according to claim 1, wherein the display device displays the generated viewing schedule as virtual channels provided on a television program guide.

### Claim 4 (depends on 1)

The information processing apparatus according to claim 1, wherein the at least one processor is further configured to: set a recording preselect in response to a predetermined manipulation to the displayed viewing schedule.

### Claim 5 (depends on 1)

The information processing apparatus according to claim 1, wherein:
the taste value is represented as a vector having the plurality of dimensions.

### Claim 6 (depends on 5)

The information processing apparatus according to claim 5, wherein:
a value of each dimension in the vector is increased with time based on user's watching content.

### Claim 7 (depends on 1)

The information processing apparatus according to claim 1, wherein:
the plurality of dimensions of the taste value comprise dimensions each associated with a respective type of genre.

### Claim 8 (depends on 1)

The information processing apparatus according to claim 1, wherein:
at least one third dimension of the taste value is associated with the on-demand content.

### Claim 9 (depends on 1)

The information processing apparatus according to claim 1, wherein the method further comprises:
if no content is selected for a time frame, recommending content for viewing during the time frame.
