The present disclosure relates to methods, apparatus or systems for inciting a user consuming an immersive content to rotate the immersive rendering device in the direction of a region of interest. According to the present principles, an object representative of a character is inserted in the field of view of the user. The character is computed in a way it looks in the direction of the region of interest from its location in the immersive content. In addition, face and body attitude of the character may reflect an emotion that is associated with the region of interest, for example scare, happiness or interest. The user will naturally be incited at looking in the direction indicated by the inserted character.

The invention relates to a method for bounding an object in a video sequence F. The method includes obtaining a subset of pixels located in the object to annotate, in each frame of the video sequence. Spatio-temporal slicing is performed on the video sequence F, centered on the obtained subsets of pixels, resulting in a first image Fobtained by an horizontal concatenation of first slices, comprising the obtained subsets of pixels, and resulting in a second image Fobtained by a vertical concatenation of second slices. A trajectory of the obtained subsets of pixels is displayed on both the first Fand second Fimage. A bounding form around the object to annotate is obtained out of four points in each frame of the video sequence, wherein the coordinates of the four points of a frame t are obtained from the coordinates of the points located in the first and second boundary of the first and second image for that frame t.

The present invention relates to a method for navigating over documents represented by identifiers displayed on a navigation menu. Each document is associated with a plurality of numerical values characterizing it according to a plurality of criteria. Each identifier of a document is placed at a position dependent on a part of the parameter values associated with this document. The whole set of the documents is subdivided into a given number of regions. The sums of the values associated with all the documents of a region and corresponding to a certain number of criteria are virtually equal for each region. The outer contour of the regions is displayed so as to enable its selection. The selection of a region triggers the display in full screen mode of all of the identifiers of the selected region. The invention also relates to a display device capable of executing the navigation method.

The invention concerns a device for multimedia data retrieval. The multimedia data is associated with an active component. The device for multimedia retrieval being characterized in that, depending on an external event, some of the active components trigger an action that make the user aware of the multimedia data associated with said active components.

A method for retrieving a media file from a media rendering device with an initial set of media files stored in the device. Each media file has attributed feature values stored in the device and is associated to a graphical element displayed on a display. The position of each graphical element on the display depends on a multitude of the feature values of the associated media file.

Method and apparatus for retrieving a media file of interest

Before the transmission of the source color values of the images of each group Gof images of this sequence, a partial color transform LUT related to this group Gis generated, then transmitted, &#x2014;and, a resultant color transform LUT related to said group Gis reconstructed by combining the transmitted partial color transform look up table of this group Gwith, if any, all the other partial color transform look up tables that have been previously transmitted, &#x2014;then each images of said group are color transformed using this LUT. The invention allows a good precision of color transformation with a limited bandwidth.

The invention concerns a method and a device to determine a descriptor for a signal representing a multimedia item. The method comprises the step of applying to said signal a first bank of directional filters in order to obtain a first set of coefficients. According to the invention the method comprises the steps of: Application to the classification and retrieval of multimedia items.

A method/apparatus for sharing a resource of plural video/audio/data signal receivers broadcast by an emitter among a plurality of video/audio/data processing Set Top Units using a Master/Slave protocol. The first STU connected to a receiver is the Master, which has priority over a later-connected slave. An STU has access to all services if there is a free receiver. In the absence of free receivers, an STU can access all the services currently accessed by the other STUs, and the services on the transport streams carrying the services currently viewed by the other STUs. A resource sharing apparatus comprises a dedicated for each STU for displaying resources available to the corresponding STU. The controller indicates Slave status for resources that can be provided for the corresponding STU and a special indication for resource that is currently used by a corresponding STU.
