A deviation amount of a pictographic character portion of 'G' is calculated based on a description of a file, and left eye-use display data (ABCDEF GIJK) and right eye-use display data (ABCDEG HIJKL) in a portion (b) in FIG.are generated. 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.

Confidential data such as license data is encrypted using the symmetric key encryption algorithm alone which requires smaller computation amount, and is readily realized by hardware elements, as compared with the public key encryption algorithm. A license-data transmitter (y) encrypts license data LIC using two keys Kscy and Kssx supplied from a license-data receiver (x). The license data is provided to the license-data receiver in the form of encrypted license data E(Kscy, E(Kssx, LIC)). This enables high-speed processing without deterioration in security even if data access such as recording/readout of data is repeated.

Method for transmission/reception of contents usage right information in encrypted form, and device thereof

When a hybrid optical disc is loaded on a player, the next generation DVD layer is reproduced in preference to the DVD layer. Jump to the DVD layer is appropriately performed based on the content of the reproduction list held in the next generation DVD. The jump to the DVD layer is performed based on the command information (jump command) held in the reproduction list of the next generation DVD layer. When reproduction of the title specified by the command information is finished after the jump to the DVD layer, the process returns to the HDDVD layer, and reproduction is performed from the position following the reproducing position at the time of the jump. Thus, the content of the HDDVD layer and the content of the DVD layer are reproduced as one stream.

A controller () designates the method of integrating viewpoint images. An image integrator () creates an integrated image by placing individual viewpoint images in appropriate positions. A 3D image control information creator () creates 3D image control information by formatting the placement mode of individual viewpoint images and various 3-dimensional image characteristics. An encoder () encodes integrated image data. A multiplexer () multiplexes the coded data and the 3D image control information and outputs them. A filename deciding unit () decides the name of a file when multiplexed data is recorded as a file. A storage directory deciding unit () decides the directory in which a file to be recorded is stored. A file creator () records a file with the decided filename under the decided storage directory. Thus, the distinction between 3-dimensional display image data and 2-dimensional image data can be clarified.

Image file creating apparatus and image file reproducing apparatus

When '0' indicating that intensity of a stereoscopic effect is the lowest is applied as a stereoscopic effect tag, a stereoscopic image is allowed to be displayed as it is. On the other hand, when '1, 2, and 3' are applied as the stereoscopic effect tag, a reduction ratio is determined depending on a value of the stereoscopic effect tag (one-half, one-third, etc.). On the basis of this reduction ratio, the stereoscopic image is displayed and letters of &#x201c;warning&#x201d; are displayed. A user selects whether to display the stereoscopic image according to a producer's intention or to maintain the size-reduced stereoscopic image. If an operation requiring for a display of the stereoscopic image as it is intended by the producer is performed, an original stereoscopic image is displayed.

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.
