Abstract: A source device for transmitting content to a sink device is provided. The source device may include an interface configured to perform high-bandwidth digital content protection (HDCP) authentication with the sink device, and a controller configured to determine an HDCP version supported by the sink device, convert the content so as to be encrypted in the HDCP version supported by the sink device in response to a determination that another HDCP version applied to the content is not supported by the sink device, encrypt the converted content in the HDCP version supported by the sink device, and control the interface to transmit the content to the sink device.

Abstract: The aim of the present invention consists of reducing the switching time from one reception channel to another. In fact, this reduction will be particularly discernable since the number of different rights stored in a security module of a multimedia unit or decoder is high. When a user selects a service among those proposed by an electronic programs guide, an access control module explores a stored service information table in order to extract an access condition associated to the service. This access condition allows determining an index in a rights table stored in the access control module of a right that fulfills the access condition. The access control module transmits to the security module the index thus determined alone or accompanied by a control message. This index allows the security module to find quickly the right that it compares afterwards with the access condition included in the control message after decryption of the latter.

Abstract: The present invention provides an extensible disc player that is upgradeable to play new content types. The player's capability can be extended by downloading an appropriate decoder from a web server via the Internet. In this way, the player can play back contents that it does not originally support. If the content type is unknown, the player will check whether the disc contains a URL for linking to a web site containing an appropriate decoder. If the disc contains the URL, the player will access the web site to download the appropriate decoder. In a similar manner, the capability of a recorder can also be expanded by downloading appropriate encoders from the Internet.

Abstract: The present invention relates to an information processing system, an information processing apparatus and method, and a program in which the purchase of content can be facilitated. When a device to which content data is downloaded and a device for giving an instruction to purchase the content data are different, a purchase form for purchasing the content data is sent to the device for giving an instruction to purchase the content data. The user ID and password are input into the purchase form, and the device to which the content data is downloaded is determined by the user ID. If the device to which the content data is downloaded cannot be specified because the user registers a plurality of devices, a destination determination form for specifying the device to which the content data is downloaded is sent. The content data is then distributed to the device indicated in the destination determination form. The present invention is applicable to a server for executing processing concerning content data.

Abstract: Information, such as audio visual information, is secured by self-decay of the information over time. For instance, a date stamp and decay rate embedded in an encrypted audio or visual digital media file can be applied to decrypt the file to a predetermined decayed state, such as a degraded playback quality. One or more keys can be included with the information to allow undecayed decryption but expire after use or a predetermined time period. In one embodiment, the decayed state can comprise gaps formed at intervals in the information, the gaps having increased length for decreased quality. In an alternative embodiment, the decayed state can be a reduced sample rate for a compressed digital media file.

Abstract: In automotive networking applications, data about vehicle's environment is used in conjunction with a control policy to manage the performance and power usage of a networked device.
