Abstract: According to a conventional technique, in the case where a program is stored into a non-volatile memory once and then activated, authentication of the program is performed immediately before such activation. However, calculations such as decryption of encrypted values are required before the activation of the program starts, which causes the problem that responsiveness is decreased in proportion to the time required for calculations. In order to solve this problem, authentication of a program is performed immediately before such program is stored, so that no authentication is performed or only a part of the authentication is performed to verify the validity of certificates at program activation time.

Abstract: There is provided a Java™ conditional access apparatus which, by describing a CA control unit through a Java™ program, obviates the need for porting a CA control program, enables development of a CA system over plural terminals in a short time, and obviates the need for terminal replacement. The Java™ conditional access apparatus includes a descramble circuit, a key generation information obtaining library, a Java™ VM, a storage unit, a condition-release control unit, an API having a registration unit. Upon receiving a function from a CA control program, the registration unit registers the received function. When the API receives information of a channel, the information of the channel to be reproduced is notified to the CA control program. The CA control program requests the key generation information obtaining library to obtain key generation information corresponding to the received channel information, and passes the received key generation information to the condition-release control unit.

Abstract: There is provided a program execution device which a user can use with peace of mind. The program execution device includes: a secondary storage unit (510) having an area for storing a downloaded application program (application); a stored application determination unit (2602) which determines, based on a priority assigned to each of plural applications, whether or not the secondary storage unit (510) can store each application; a notification unit (2605) which notifies the user of a message regarding treatment of an application determined by the stored application determination unit (2602) to be unstorable; a storage unit (2603) which stores, in the stored application determination unit (2602), an application determined by the secondary storage unit to be storable (510); and a CPU (514) which executes the application stored in the secondary storage unit (510).

Abstract: There is provided a display processing device that increases graphics display performance, including: an OSD plane (211) having a first OSD area (671) and a second OSD area (672) for storing graphics images; a Z-order management unit (601) which stores a vertical order assigned to the first OSD area (671) and the second OSD area (672), and which provides a notification regarding that vertical order; a CPU (217) which executes a downloaded application (506), thereby storing the graphics images in the first OSD area (671) and the second OSD area (672) based on the vertical order notified by the Z-order management unit (601); and a display (212) which superimposes the graphics images stored in the first OSD area (671) and the second OSD area (672) in accordance with the abovementioned vertical order, and displays the images.

Thus, the start-up time appears to be shortened. Further, the present invention provides the information regarding the action state of the embedded program to the Java program, thereby enabling a consistent execution of the Java program on completion of the Java program start-up process.

Abstract: When requested by an application, a library unit provides a resource to the application, acquires an ID for identifying the application which has requested the resource, and stores a combination of a resource name of the provided resource and the application ID in a table. When an application is completed, the library unit receives an application ID of the completed application, detects a resource name corresponding to the received application ID in the table, and collects a resource specified by the resource name.

Abstract: Conventionally, when the version of a program has been upgraded, the whole of a currently stored program needs to be deleted to be replaced by a new program, and authentication needs to be performed again on such new program when it is activated. However, since the whole of the program is required to be stored and authenticated even when only a part of such program has changed, it consumes time and leads to the decrease in responsiveness. In order to solve this problem, the present invention extracts a difference between a new program and a currently stored old program, when such new program is to be stored, and the new program is to be stored after authentication is performed only on such difference.
