    摘要: The present invention provides a solution to protect network data stored on a network unit within a network related to a carrier data stored on a record carrier. A copy protection system already provided for protecting a carrier data is used therefore so that in a key locker stored in a key locker area (22) of the record carrier (2) a network dat identifier (URL) identifying the network data to be used for retrieval of said network data om the network (4) and a decryption key (DK) to be used by a read-out device (1) for d cryption of encrypted network data are stored. The network data identifier (URL) is used to et access to the network data, and the decryption key (DK) is thereafter used to decrypt enc pted network data if access to the network data is permitted.

    摘要: A rewritable storage medium comprising predefined content which is adapted for being integrated with additional user-defined content is described, the storage medium comprises: a first portion comprising said predefined content; a second portion for adding said user-defined content; wherein said predefined content in said first portion comprises links to said second portion. Thereby the user can customise the predefined content on the storage medium by adding personal content being an integrated part of the predefined content. Further the user can make dedicated annotations and comments on each category he visits, the connection is built up by the dummy links. According to the invention the user's own content is integrated with the published part of the disc giving an easily personalised guide book. In more general terms the user buys disc content with some prepredefined content, which can be enhanced by user's own content in a seamless way.

    摘要: An audio encoding scheme or a stream that encodes audio and video data is disclosed. The scheme has particular application in mezzanine-level coding in digital television broadcasting. The scheme has a mean effective audio frame length F that equals the video frame length 1/fV over an integral number M video frames, by provision of audio frames variable in length F in a defined sequence where length=F(j) at encoding. The length of the audio frames may be varied by altering the length of overlap between adjacent frames in accordance with an algorithm that repeats after a sequence of M frames. An encoder and a decoder for such a scheme are also disclosed.
