    • 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.
    • 提供了一种Java TM条件访问装置,其通过Java TM程序描述CA控制单元,从而避免了移植CA控制程序的需要,使得能够在短时间内在多个终端上开发CA系统 ,并且不需要终端更换。 Java TM条件访问装置包括解密电路,密钥生成信息获取库,Java TM VM,存储单元,条件释放控制单元,具有注册单元的API。 一旦从CA控制程序接收到功能,注册单元登记接收到的功能。 当API接收到信道的信息时,将要再现的信道的信息通知给CA控制程序。 CA控制程序请求密钥生成信息获取库以获得与接收到的信道信息相对应的密钥生成信息,并将接收到的密钥生成信息传递给条件释放控制单元。

    • 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).
    • 提供了一种用户可以安心使用的程序执行装置。 程序执行装置包括:副存储单元(510),具有用于存储下载的应用程序(应用程序)的区域; 存储应用程序确定单元(2602),其基于分配给多个应用程序中的每一个的优先级来确定辅助存储单元(510)是否可以存储每个应用程序; 通知单元,其向用户通知关于由所存储的应用程序确定单元(2602)确定的应用程序的处理的消息是不可以的; 存储单元(2603),其在所述存储应用确定单元(2602)中存储由所述辅助存储单元确定为可存储的应用(510); 以及执行存储在二次存储单元(510)中的应用的CPU(514)。
