1. A content reproduction apparatus comprising:
- a content reproduction unit operable by a user for reproducing content;
a habit detection unit for accumulating indications of the user'"'"'s past operation of the content reproduction unit to calculate a probability value of type of content reproduced by the user, time that the content is reproduced and delivery channel over which the content is reproduced, thereby determining the user'"'"'s reproduction habit based on the calculated probability value when the user operated the content reproduction unit; and
an abnormality determination unit for receiving information relating to current operation of the content reproduction unit by the user, for comparing the received information to the determined user'"'"'s reproduction habit, and for determining an abnormality in the user'"'"'s actual use of the content reproduction unit when an actual user operation differs from an expected user operation as estimated from the calculated probability value.

Abstract
There is provided a content reproduction apparatus including a content reproduction unit for reproducing content, a habit detection unit for detecting a reproduction habit regarding content that uses the content reproduction unit, and an abnormality determination unit for determining there is an abnormality, in a case a reproduction action estimated from the reproduction habit detected by the habit detection unit is not carried out.

4. A content reproduction apparatus comprising:
-
a content reproduction unit for reproducing content; a habit detection unit for detecting a user'"'"'s reproduction habit regarding content that uses the content reproduction unit to estimate the reproduction of content; a content comparison unit for comparing, when the reproduction of content estimated from the detected reproduction habit is not carried out, first content currently being delivered and second content which was being delivered, at the time of detection of the reproduction habit, in a time slot same as that of the first content; a taste detection unit for detecting a user'"'"'s taste in content by analyzing a type of content reproduced by the user'"'"'s use of the content reproduction unit; a taste determination unit for determining, when an estimated content ending action is not carried out and the result of comparison by the content comparison unit indicates that the first content and the second content are of different types, whether or not the first content matches the taste of the user detected by the taste detection unit; and an abnormality determination unit for determining there is an abnormality when the estimated content ending action is not carried out, the result of comparison by the content comparison unit indicates that the first content and the second content are of different types, and the taste determination unit determines that the first content does not match the detected taste of the user. - View Dependent Claims (5, 7, 8, 9, 10, 11, 12, 13, 14)

15. An abnormality detection method comprising the steps of:
-
reproducing content; accumulating indications of a user'"'"'s past operation to reproduce content to calculate a probability value of type of content reproduced by the user, time that the content is reproduced and delivery channel over which the content is reproduced, thereby determining the user'"'"'s reproduction habit based on the calculated probability value when the user reproduced content; receiving information relating to the current reproduction of content by the user; comparing the received information to the determined user'"'"'s reproduction habit; and determining an abnormality in the manner in which the user actually reproduces content when an actual user operation differs from an expected user operation as estimated from the calculated probability value.
