摘要： This invention relates to a service providing system and a service providing method for allowing users to receive a service from a service server without having to submit their security-critical information to that server. A CE device 1 requests provision of the service by transmitting authentication information such as a device ID to a surrogate authentication server 2. The surrogate authentication server 2 authenticates the CE device 1 based on the authentication information and transmits a result of the authentication to the service server 3. In turn, the service server 3 provides the CE device 1 with the requested service based on the result of the authentication received from the surrogate authentication server 2. The CE device 1 then uses the service provided by the service server 3. This system can be applied advantageously to network-based marketing systems.

摘要： The present invention provides a device-authentication system capable of efficiently performing authentication before using a service through a network. A CE device (3) includes a browser (9) for accessing a service server (4) and an authentication module (7) for allowing an authentication server (5) to perform device authentication. A device-authentication plug-in (8) is a plug-in having a function of starting the authentication module (7). The device-authentication plug-in (8) can be specified by a predetermined MIME format, and the browser (9) starts the device-authentication plug-in (8) after receiving an EMBED tag having the MIME format.

摘要： By describing electrical program guide information in a language such as XML and then multiplexing the electrical program guide information to a broadcast signal for transmission, advertisements, images and sounds can be easily entered and various program guides can be realized. For manufacturers of receiving devices, it suffices to develop only the software for receiving, decoding and displaying received XML data. There is no need to develop the software for displaying the EPG for each type of receiving device. Thus, the number of development steps can be reduced.

摘要： In a digital receiver which can easily store broadcast information, a one-period amount of data is separated from a data broadcast signal. The one-period amount of data has an amount of data corresponding to plural frames which are periodically repetitively transmitted in the data broadcast signal. The one-period amount of data is stored in a data storage device, thereby simplifying the construction of the data storage device.

摘要： Guide information is provided relating to playing/viewing of content retrieved through various modalities such as television broadcasting and a computer network. A unified program list is created that comprehensively handles program content. For a self-recorded program, program metadata retrieved during a recording operation is additionally registered. For a network program, a network program list is periodically retrieved from a service site, modified and recorded. To play the content, a guide screen is created and supplied based on a unified program list. When a self-recorded program is selected, the program is read and played from an HDD. When a network program is selected, the program is played in a streaming manner via the Internet.

摘要： The protection of data against illicit transfer with respect to specific data can be ensured. An integrated receiver decoder determines whether or not ATRAC (Adaptive Transform Acoustic Coding) data requiring authentication is contained in selected piece-of-music data in accordance with determination data added into transmitted data. When ATRAC data requiring authentication is contained, the integrated receiver decoder performs an authentication process between it and a storage which is a transfer destination of the ATRAC data, and performs downloading of the ATRAC data after confirming that the storage is a valid apparatus to which the downloading may be performed.
