Abstract: A method for post-synchronizing information stream includes obtaining lip-objects from a video signal. The original lip-objects are replaced with new lip-objects which correspond to a translated audio signal. The new lip-objects may be obtained by tracking a further video signal or by using a database with visemes or lip-parameters. For a multi-language information stream, a desired language may be selected at the receiver.

Abstract: The invention concerns an apparatus and method for the gathering of data relating to aspects of a user's surroundings, particularly to the logging and subsequent retrieval of environmental data. In embodiments of the invention, the apparatus comprises one or more logging stations (10), a data bank (20), a user station (30) and a contributor station (40). Each user has a user identifier card (50) on which logging preferences may be stored. Each logging station (10) is arranged for recognizing a period during which a user is present, and logging personal data according to the logging preferences while the user is present. Further, when the user is no longer at a particular logging station (10), the logging station in question transmits information including user ID and logged data to the data bank (20), from which the user station (30) may later retrieve the information.

Abstract: The invention provides a method for post-synchronizing an information stream. Original lip-objects (lo) are obtained (2) from a video signal (V). These original lip-objects (lo) are replaced (3,4) with new lip-objects (lo*), which correspond to a translated audio signal (A*). Lip-objects (lo) can be obtained from the video signal (V) by using an object-oriented coding technique, e.g. MEG-4. The coding standard MPEG-4 offers the facilities to manipulate the lip-objects (lo). Several configurations are presented. The new lip-objects (lo*) can be obtained by tracking a further video signal or by using a database with visemes or lip-parameters. The invention is suitable for a communication network, e.g. for video-conferencing. A multi-language information stream comprises a plurality of audio signals (A,A*) and a plurality of lip-objects (lo,lo*) that are each linked to one of the audio signals (A,A*). This gives the possibility to select at the receiver a desired language.
