    • PROBLEM TO BE SOLVED: To provide video equipment for enabling a user or a content viewer to operate a plurality of images arbitrarily to record an intended image stream efficiently for reproduction in the video equipment handling the image stream containing a plurality of images, such as a moving picture, a menu button, and a caption; and to provide a method of recording images, and a method of reproducing images. SOLUTION: There are provided a processing means S11 for arranging a plurality of kinds of images at coordinates on one image without any overlapping and generating a source image A, for generating information 105 for image restoration for cutting the plurality of kinds of image 101-103 from the source image A individually, and for encoding the generated source image; and a processing means S12 for adding the information for image restoration and prescribed information B for image output to the data of the encoded source image, for generating image unit data C, and for recording the image stream D comprising a collection of the image unit data on an information storage medium E.

    • PROBLEM TO BE SOLVED: To allow the copyright of a content to be protected by efficiently restricting the number of replicated contents. SOLUTION: This storage device has identification information and is provided with: a storage means including an identification information storage area for storing the identification information, a secret area accessible by a hidden specific procedure, and an open area other than the secret area; and a control means for executing the specific procedure for accessing the secret area to determine whether the secret area is accessible or not and for enabling access to the secret area when it is accessible. An encrypted content and first control information encrypted by key information generated based on the identification information and required for a reproduction process of the encrypted content are stored in the open area; and second control information for generating the key information required for the reproduction process of the encrypted content is stored in the secret area.
