Abstract: It is determined whether key information is valid or invalid on the basis of first key management information indicating an expiration date of a terminal when a playback request for encoded content is input. When it is determined that the key information is invalid, an invalidation date of a key set in the first key management information with an encoding date of content stored in a recording medium. As the determination result, if an expression, encoding date<invalidation date is established, encoded content is determined to be legal content. On the contrary, if an expression, encoding date?invalidation date, the encoded content is determined to be illegal content.

Abstract: A memory to store a state identifier showing whether or not to permit reading out an occurrence number of times of disk shifts from a disk storage unit is newly provided so as to intermittently change the identifier from a first state to a second state. When access requests to the disk unit are made, information showing the occurrence number of times of the disk shifts is read from the storage unit along with a data writing or reading operation to and from the storage unit. After a completion of reading the information, the identifier is returned from the second state to the first state. The identifier is changed from the first state to the second state with a determined time interval which is set longer than, for example, a minimum value of occurrence time intervals of the access requests.

Abstract: When a two-dimensional tomogram is to be displayed, motion information associated with a direction orthogonal to the tomogram is colored and mapped on the tomogram to be visualized by using the volume data of a TSI image. For example, a mapping image is generated by color-mapping shortening information at each point on a cardiac tissue on a short axis view by using the volume data of the TSI image. Superimposing and displaying the mapping image on the original short axis view makes it possible to simultaneously observe the shortening information even while a short axis view is obtained and observed.

The third lens is formed with an inflection point where the curvature orientation changes within the effective diameter range of the aspherical surface on the image-plane side. An appropriate back focus is maintained while the total length of the lens system is reduced.

Abstract: The ultrasonic diagnostic system estimates a desired time phase or one cycle period of a moving region (e.g., a heart) that repeats contraction and relaxation cyclically and which can be specified by a presystole, an end systole, a prediastole, an end diastole, and other clinical characteristics for one cycle of the moving region on the basis of the velocity information on multiple positions of the moving region which is obtained for each time phase. More specifically, assuming that, for example, the end systole phase=a time phase in which the myocardial velocity comes to zero or close to zero, the system calculates |myocardial velocity| for each time phase in a predetermined period, and estimates a time phase in which this value comes closest to zero as an end systole phase.

Abstract: Screen display matched to the progress of execution of the initialization function in small and inexpensive devices such as a portable terminal is performed. Furthermore, reliability in the event of an error is improved without providing excessive redundancy and with limited capacity in a NAND flash memory storing programs. A first boot layer and a second boot layer of the same content are stored in the NAND flash memory. The boot layer free from errors is copied (C2) to a RAM (step S21), and a boot layer program is executed in the RAM (step S30). A simple logo and the like comprising characters is then displayed (first screen display) (step S32). Next, a system layer program is executed in the RAM (step S40). A screen (second screen display) is then displayed by switching between a plurality of images (step S44).
