摘要： According to a data display method, data having a program unit and instruction data for the program unit multiplexed on bit stream data is received. The program unit is extracted from the received data and is stored in a memory. The instruction data is extracted from the received data, and the program unit or part thereof specified by the instruction data is read from the memory and is executed. Then, the bit stream data and the execution result are displayed. This ensures smooth synchronization of reproduction of a bit stream with execution of an associated program and efficient use of resources.

摘要： According to one embodiment, a storage device includes a data storage unit, a receiving unit, a selecting unit, and an authenticating unit. The data storage unit includes a secret area that becomes readable when authentication has been made by using reading authentication information and that becomes writable when authentication has been made by using writing authentication information. The receiving unit receives an access request that is either a write request indicating that data should be written into the secret area or a read request indicating that data should be read from the secret area. The selecting unit selects the writing authentication information if the access request is the write request and selects the reading authentication information if the access request is the read request. The authenticating unit authenticates an access to the secret area by using one of the writing authentication information and the reading authentication information that has been selected.
