Therefore, when the content data is recorded in conformity with the DVD standard, the content data and the main function control information and the additional function information can be integrally configured. Of course, there is no need to separately prepare scene identification information for identifying the scene. Therefore, the information reproducing apparatus is suitable for a content recording medium on which content data is recorded in compliance with the DVD standard.
- the content recording medium of the present invention may have the content data and the additional function information recorded thereon so that the content recording medium can be supplied to the information reproducing apparatus.
- additional function information for performing control according to content in response to a user operation input can be provided together with content data. It is desirable that the additional function program specified by the additional function information is also recorded on the same content recording medium as the content data and the additional function information.
- the control program of the present invention is a computer program that causes a computer to function as each of the above means.
- the information reproducing apparatus can be realized by realizing each unit of the information reproducing apparatus by a computer.
- a computer-readable recording medium on which the control program of the present invention is recorded is a computer-readable recording medium on which a control program for operating the information reproducing apparatus is realized by realizing the above-described units in a computer. It is.
- control program read from the recording medium allows the control program
- the information reproducing device can be realized on a computer.
- the information reproducing apparatus (AV data reproducing apparatus) of the present invention
- a function different from the original function assigned to the operation input can be executed, and the content is responded to the user's operation input. Since the control can be performed flexibly, it can be widely applied to a player that reproduces AV data from a recording medium such as a DVD.
