Abstract: A function managing apparatus allows a user to avoid a fault likely to occur in a user terminal before a new function is installed on the user terminal. A function managing apparatus for communicating with a user terminal is provided. Specifically, the function managing apparatus includes a receiving unit, predicting unit, and alerting unit. The receiving unit receives from the user terminal the new function ID identifying the new function to be installed on the user terminal, and the installed function IDs identifying one or more functions previously installed on the user terminal. The predicting unit specifies the new function and one or more installed functions based on the new function ID and installed function IDs received by the receiving unit, and predicts the result when the new function is installed on the user terminal. The alerting unit notifies the user terminal of the prediction result of the predicting unit.

Abstract: In a recording/reproducing system RRS1, an I-picture detecting section 15 generates, from a transport stream DETS output from a descrambler 13, a control signal CS indicating a bit location of a TS packet including a part of an I picture for output. Based on the control signal CS, a TS header processing section 16 specifies a TS header added to a payload of an I picture from the transport stream TS, and changes a value of a reserved bit in the TS header from 0 to 1. In high-speed replay, a storage unit SU1 refers to the reserved bit of the TS header to select only an I-picture transport packet required for high-speed replay, and composes a transport stream PRTS for transmission to a decode unit DU1. Thus, high-speed replay can be easily achieved.

Abstract: A memory card 13 includes wireless network communication unit for having electronic equipment to access a storage server 11 on a network. The storage server 11 includes at least a non-authentication area 111. Data such as contents is written into a non-authentication area of the memory card 13 or the non-authentication area 111 of the storage server 11. In other words, an area of a storage area to which data can be written is expanded by the non-authentication area 111 of the storage server 11. Thus, the non-authentication area of the memory card 13 increases apparently. Encoding key used for encoding and decoding contents protected by copyrights is written to an authentication area on the memory card 13. Anyone can access content data in the non-authentication area 111 of the storage server 11, but an encoding key required for decoding the content is in the memory card 13.

An event detection section (205) detects a predetermined event. A service retrieving section (206) retrieves a service corresponded to the detected event. A service execution section (207) determines an application program related to the retrieved service, and another terminal device which cooperatively executes the application program. Then, the service execution section (207) instructs an application management section (203) and an application execution section (204) of the own terminal device and the other terminal device to obtain and execute the program.
