摘要： A video display apparatus includes: a tone mapping processor that performs a tone mapping process of converting a luminance of a video by using conversion characteristics according to a maximum luminance of the video; and a display that displays the video that has undergone the tone mapping process. The tone mapping processor switches between a first tone mapping process of dynamically changing the conversion characteristics according to a time-depend change in the maximum luminance of the video and a second tone mapping process that is performed using constant conversion characteristics irrespective of the time-depend change in the maximum luminance of the video. When the tone mapping process used is switched from the second tone mapping process to the first tone mapping process, the conversion characteristics used is changed gradually or stepwise from the constant conversion characteristics to dynamically changing conversion characteristics over a plurality of frames.

摘要： To provide a content playback device capable of protecting content according to DRM, when decrypting encrypted content recorded on a recording medium and playing the decrypted content. If key generation information is “00”, a key control unit 104 concatenates a decrypted media key and content information in this order, and applies a one-way function to the concatenation result to generate a content key. If the key generation information is “10”, the key control unit 104 sets a rights key as the content key. If the key generation information is “01”, the key control unit 104 concatenates the decrypted media key and the rights key in this order, and applies a one-way function to the concatenation result to generate the content key.

摘要： The reading unit reads an application program, image data, a video stream, and an application management file from a recording medium. The virtual machine unit executes the application program. The memory unit includes an image data area for storing the image data. The playback unit plays back video data with use of the image data and the video stream in accordance with the application program. The management unit, in accordance with the application management file, instructs the virtual machine unit to start and terminate the application program and instructs the memory unit to change the image data area. Before instructing the memory unit to change the image data area, the management unit causes the virtual machine unit to forcibly terminate the application program even when the application management file specifies the continuous execution of the application program.

摘要： The media inherent key storing unit 220 prestores an inherent key Ki, the conversion unit 230 generates an encrypted inherent key Ji from the inherent key read from the media inherent key storing unit 220, the random number generating unit 331 generates a random number R1, the encryption unit 252 generates an encrypted random number S1, the decryption unit 333 generates a random number R′1 from the encrypted random number R1, and the mutual authentication control unit 334 compares the random number R′1 with the random number R1 and, if the random number R′1 matches the random number R1, judges that the memory card 200 is an authorized device. If the memory card 200 and the memory card writer have successfully authenticated each other, the memory card writer encrypts a content using a decrypted inherent key. If the memory card 200 and the memory card reader have successfully authenticated each other, the memory card reader decrypts an encrypted content using the decrypted inherent key.

摘要： A recording medium capable of executing menu calls based on the particular characteristics of different versions of the same movie work when these different versions are recorded on a single recording medium. An AV clip and a dynamic scenario are recorded on a BD-ROM 100 (recording medium). The dynamic scenario is a command string showing a playback control procedure relating to video data, and has attribute information attached thereto. Attribute information is information showing a control procedure for when a user requests a menu call during AV clip playback, and includes a resume_intension_flag. The resume_intension_flag shows whether playback resumption of video data after the menu call ends is intended.
