Abstract: How to allow requests and data, which are relevant to a service using an IC (Integrated Circuit), to be exchanged among a SAM unit serving as a data-processing apparatus, a server and the integrated circuit with a high degree of efficiency in an operation to render the service. The server transmits a first command requesting an IC module (the integrated circuit cited above) of a portable communication apparatus to carry out processing to the SAM unit. The SAM unit interprets the first command and transmits a second command for operating the IC module in accordance with a result of interpretation of the first command to the IC module by way of the server. The IC module carries out the processing in accordance with the second command and transmits a first response containing a result of the processing to the SAM unit by way of the server.

Abstract: An application program comprises a plurality of 1st application elements each having a plurality of versions. In this case, the versions are managed by using version management data each used for managing relations between a plurality of 2nd application elements each corresponding to one of the versions and the 1st application elements, and by using management data for managing relations between the 1st application elements and the version management data. As a result, it is possible to provide a data-processing apparatus capable of properly restricting users setting application programs in a server for security reasons.

Abstract: An information processing method has a mechanism wherein mutual verification is performed between tasks and a computer operating system at the time of activating tasks, thereby judging the validity of tasks. The operating system evaluates a key which the task holds at the time of requesting service of the operating system, and permits execution of services only in the event that the operating system itself has the same key. A mail transmitting task specifies a mail ID and address to a mail body, management information is written by the operating system to a secure memory queue list based on the security level of the mail transmitting task and the security level of a transmitting function, and contents wherein mail transmission contents are enciphered with the mail ID, address value of management information, and address value of the mail body, as a key, are written to a buffer.

Abstract: A work memory for storing a compressed audio stream to be decoded, a plurality of decoding process sections, and a plurality of output process sections are provided. A control section switches the start and stop of a decoding process between each decoding process section in predetermined switching cycles so that only any one of the decoding process sections uses the work memory to perform a decoding process at any single point of time, and saves, into an outside of an audio decoding apparatus, a compressed audio stream stored in the work memory which has been referenced by a decoding process section to be caused to stop a decoding process. When a stopped decoding process section is caused to resume a decoding process, the control section reads a compressed audio stream saved for the decoding process section to be caused to resume the decoding process, from the outside.

Abstract: An information processing system having a mechanism wherein mutual verification is performed between tasks and a computer operating system at the time of activating tasks, thereby judging the validity of tasks. The operating system evaluates a key which the task holds at the time of requesting service of the operating system, and permits execution of services only in the event that the operating system itself has the same key. Management information is written by the operating system to a secure memory queue list based on a security level, and a key is written to a buffer. The operating system deciphers the contents of the buffer wherein the received contents exist, with the key, based on the security level, and copies this onto a buffer on the mail receiving task.

Abstract: A decoding/outputting section decodes encoded data. A decoding error determination section determines presence/absence of a decoding error each time the encoded data is decoded by the decoding/outputting section. A storing section stores determination results in a chronological order. A determination section determines whether the number of determination results indicating “decoding error”, among latest N consecutive ones of the determination results stored in the storing section, is greater than or equal to M. A control section has a normal mode in which the control section limits an output of the decoding/outputting section based on a determination and an error mode in which the control section unconditionally limits an output of the decoding/outputting section irrespective of the determination result. The control section transitions to the error mode when the determination section determines that the number of determination results indicating “decoding error” is greater than or equal to M.

Abstract: In a compression process (S10), each allocation table is converted by reducing each group of subbands sharing a common pattern to one (S11), and the allocation tables are further converted into a single table (S12). Then, offset values each corresponding to one subband are defined in a table (S13), and these tables are stored in the memory (S14). In a decoding process (S20), an offset value is obtained using a subband as a key (S21), and the number of quantization steps is obtained from a pattern read out from the table using the offset value (S22).

Abstract: The multimedia data decoder includes a decoding section and a control section. The decoding section for decoding coded data in a bit stream has a function to detect a synchronous word from the bit stream, analyze decoding information following the synchronous word and extract specific option designating information from the decoding information. The control section determines whether or not the option designating information extracted by the decoding section has any out-of-standard value, that is, any value that is not defined by a standard. If the option designating information has any out-of-standard data, the control section controls the decoding section so as to replace the out-of-standard value with a value defined by the standard and conduct a decoding process. For this purpose, the control section applies replacement information to the decoding section. Accordingly, decoded data is obtained even if the decoding information has an out-of-standard value.
