摘要： The invention relates to a method of operating with content items, generating of a user preference profile, and introducing new content items in a community-based recommendation system. A virtual user terminal (115) determines a new user preference profile when detecting the availability of a new content item. The virtual user terminal (115) comprises an initialization processor (123) which sets a preference value in the user preference profile for the new content item. The virtual user terminal (115) further comprises a relation processor (125) which determines related content items, and a profile processor (127), which sets preference values in the user preference profile associated with the at least one related content item. Hence, an association is formed between the first content item and the related content items, thereby linking the new content item to existing content items, and thus increasing the probability that the new content item is recommended.

摘要： The invention relates to a system for providing a selection list of content items to a user. The content items may comprise video content, audio content and multimedia content including received or recorded TV or radio programmes. An apparatus comprises a content receiver (103) for receiving content items. The content items may be stored in a content memory (105). The apparatus further comprises a duration processor (111), which determines a content item duration indication for each of the content items. A content item list processor (113) generates an ordered content list comprising content items ordered in response to the content item duration indication. The ordered list is presented to the user as a selection list by a user interface (107). The user may select a content item for presentation by highlighting the content item in the selection list. The content item duration indication may relate to a remaining time of a programme.

摘要： A method and system which enable a user to query a multimedia archive in one media modality and automatically retrieve correlating data in another media modality without the need for manually associating the data items through a data structure. The correlation method finds the maximum correlation between the data items without being affected by the distribution of the data in the respective subspace of each modality. Once the direction of correlation is disclosed, extracted features can be transferred from one subspace to another.

摘要： When booting a personal computer, it needs to find instructions immediately to tell it what to run to start up the personal computer. These it finds within the so-called basic input/output system (BIOS) program. Usually the BIOS program is stored in a separate location, for example a ROM. It is usually shadowed into system memory (SM) to speed up its operation. The copying of the BIOS program to system memory (SM), amongst others, causes the boot process to be a relatively slow process. In the present invention, the system memory (SM) comprises a persistent system memory (PSM) and the BIOS program is stored in the persistent system memory (PSM). Furthermore, selected information used by the BIOS program is stored in persistent system memory (PSM) as well. As a result, the speed of booting the personal computer is significantly increased.

摘要： The present invention relates to a method and a system for identifying an item (1) to which a radio frequency tag is attached by means of a radio frequency tag detector (101), wherein radio frequency contact is established between the tag and the detector (101) and information associated with the item (1) and being stored by the tag is received by the detector (101). The invention is based on the idea that the data stored by the tag is mapped against a unique item identifier. This unique item identifier is then presented for a user of the detector (101). By employing the present invention, it is possible to identify an item (1) by attaching a small tag to it. This is particularly advantageous in the case where the item (1) to which the tag is attached is very small, such that it is practically difficult to write information on the item (1) itself or on the item casing.

摘要： The present invention relates to methods and a system for managing digital rights. The invention is based on the idea that a digital voucher (100) is provided with access control information for accessing digital content located on a server (104) of a content provider. A consumer of the digital content reads the voucher (100) by means of a bar code reader, an RF detector (102) or the like. This reading means (102) is connected to some computing means (103) such as a computer, a mobile phone, a PDA, a set-top box etc. The computing means (103) transfers the access control information to a server (104) of a content provider. The server (104) to which the access control information is transferred processes the access control information, and depending on the result of the processing, the computing means (103) is given different levels of access to digital content located on the server (104).

摘要： Methods of and devices (D1) for authorizing an operation requested by a first user (P2) on a content item (C1) in accordance with a user right (UR1). The user right may identify the first user or a second user (P1) and authorizes the user in question to perform the requested operation on the content item. If the user right identifies the second user, the operation is authorized upon receipt of information linking a user right of the first user and the user right of the second user. Preferably the information comprises one or more domain certificates (DC1, DC2) identifying the first and second users as members of the same authorized domain (AD). Preferably a content right (CR1) enabling the operation is used, whereby the user right authorizes the second user to employ the content right.

摘要： A system and method provides a realistic architecture and specifies the protocols that are necessary for carrying out adaptive and efficient protection, thereby allowing applications to dynamically switch between different protection strategies. Protection is uniquely achieved by providing the protection track (206, 208, 210) as a separate stream from the media data stream (202, 204). In this manner, changing the protection data can change the protection level or strategy, but the protection procedures remain the same. Further, the method uses Real-time Transport protocol (RTSP) instead of Internet Group Management protocol (IGMP) which can achieve faster protection and provide more flexibility to applications.

摘要： In a method for processing audio signals composed audio signals (L+R) and (L-R) are derived from left (L) and right (R) audio signals. The energy content of the composed (L-R) audio signals above a predetermined frequency value is measured and compared with a predetermined threshold value. Then, when this energy content falls below said threshold value, a signal derived from and decorrelated with respect to the composed (L+R) audio signal is added to the composed (L-R) signal to obtain an improved composed (L-R) audio signal, and left (L) and right(R) audio signals are obtained back again from the composed (L+R) signal and the improved composed (L-R) audio signal.
