摘要： A memory card (110) conducts an authentication process with a server based on data stored in an authentication data hold unit (1400). The memory card (110) extracts a first session key (Ks1) from a server by a decryption process and a transaction ID from the data applied on a data bus (BS3). The memory card (110) generates a second session key (Ks2) through a session key generation unit (1418), and transmits to the server, as the keys to encrypt content data in receiving decryption of content data, the second session key (Ks2) and a key (KPm(1)) unique to the memory card (110) in an encrypted state with the first session key (Ks1). The transaction ID and the second session key (Ks2) stored in the log memory (1460) are used in the redistribution process.

摘要： A license server (10) includes a CRL database (306) holding a revocation list recording therein classes predetermined corresponding respectively to a memory device, such as a memory card, and a content reproduction circuit, such as a cellular phone, that are subjected to revocation of distributing, reproducing and transferring content data. A distribution control unit (315) suspends an operation distributing content data if the distribution is addressed to a class listed on the revocation list. The revocation list is also held in the memory card and distribution control unit (315) in distributing content also transmits information for updating the revocation list in the memory card.

摘要： A cellular phone (100) stores encrypted content data and encrypted license key distributed thereto in a memory card (110). The cellular phone (100) and the memory card (110) collectively perform a part of mutual authentication processing upon power-on. The encrypted license key (Kc) read from the memory card (110) is decrypted by a first decryption processing portion (1510) with a session key (Ks4), and is further decrypted by a second decryption processing portion (1514) with a system symmetric key (Kcom) for extraction. A third encryption processing portion (1516) decrypts the encrypted content data read from memory card (110) with the license key (Kc) to reproduce content data (Data).

摘要： In a cellular phone, a controller stores content data received from a distribution server into a memory. When the content data is to be transmitted to a memory card, a random number key generator generates a license key, and an encryption processing unit encrypts the content data using the license key. The controller transmits encrypted content data to a memory card via a memory card interface. Then, the controller deletes the content data stored in the memory. As a result, distribution of content data that must be deleted when transferring to another apparatus can be facilitated while protecting the copyright.

摘要： [problem] New functions including fade-in and fade-out are provided in view of particularity of three-dimensional image display. [means to solve the problem] During a fade-out process, a left-eye image (L image) is moved in a left direction while it is gradually reduced in size, and a right-eye image (R image) is moved in a right direction while it is gradually reduced in size. Thus, parallax between the L image and the R image is gradually increased. When the image is viewed through a 3D filter, it appears as if a subject to be displayed on a still image were gradually drawn in a depth direction. Furthermore, this effect can be magnified when the sizes of the L image and the R image are gradually reduced.

A starting location of a description of “ABCDEFGHIJKL” is specified by an X coordinate and a Y coordinate described in the file. In addition, a process of alternately writing pixel data constituting the left eye-use display data (ABCDEF GIJK) and pixel data constituting the right eye-use display data (ABCDEG HIJKL) from a pixel data storing location of a VRAM corresponding to the coordinates (that is, one right eye-use pixel and one left eye-use pixel are alternately written one after another in a horizontal direction as a display image) is carried out.
