摘要:
A transmission method in a video apparatus connected to a database system of visual entities is disclosed. The method comprises: - selecting (12, 32) a first visual entity in the video content; - selecting (14, 35) a second visual entity in the video content; - transmitting (16, 38) to the database system at least one information relative to an association of the first visual entity with the second visual entity. A receiving method in a database system of visual entities associated with metadata, the database system being connected to a video apparatus, is also disclosed.
摘要:
A method and an apparatus for generating an explanation for a recommendation based on the content of a recommended multimedia content item and a multimedia content item forming the basis for the recommendation are described. Concepts associated to the recommended multimedia content item are compared (21-25) with vertices of a directed graph to associate the recommended item to a first vertex of the directed graph. The vertices of the directed graph represent concepts derived from one or more knowledge bases. Then a multimedia content item that has been previously accessed by the user is selected (31). Concepts associated to this previously accessed multimedia content item are compared (21-25) with vertices of the directed graph to associate the previously accessed multimedia content item to a second vertex of the directed graph. Subsequently a path between the first vertex of the directed graph and the second vertex of the directed graph is determined (32) using edges of the directed graph. Finally, the determined path is provided (33) to the user as an explanation for the recommendation.
摘要:
A method of and device configured for transmitting data representative of an image, the method comprising: obtaining a first parameter representative of a visualisation direction associated with a first image representative of a first part of a scene, the first image corresponding to a first part of a large field-of-view content; updating a body model by applying the first parameter to the body model; comparing at least a second parameter of the updated body model to at least a reference value to determine a first level of visualisation comfort; and transmitting data representative of a second image when the first level of visualisation comfort is less than a determined level, the second image being representative of a second part of the scene, the second part of the scene being different from the first part of the scene.

The present disclosure relates to methods, apparatus or systems for managing a map of haptic atmospheres over a topographical zone. The zone may contain relief or noticeable objects. A set of devices equipped with haptic sensors and haptic actuators is wore by a set of users spread over the topographical zone. Each device is contributing to the management of the map by sending its localized haptic measurements to a server. The server calculates and maintain the map according to these spread measurements. Client devices also send request to get a haptic effect representative of the haptic atmosphere around a second location in the topographical zone. The server calculates the response according to this second location and to the characteristics of the client.
摘要:
The invention relates to a method and an apparatus (50) for providing information for a multimedia content item (10) from a catalog of multimedia content items (10) to a user with the capability of displaying intra-content and inter-content information. A sequence (24) of concepts is generated for the multimedia content item (10) using a concept graph (20) and metadata (14) associated to the multimedia content item (10). An enhanced sequence (44) of concepts for the multimedia content item (10) using the sequence (24) of concepts and an enhanced concept graph (26). The enhanced sequence (44) of concepts is then displayed to a user.
