Abstract: 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.

Abstract: In a context of varying ambient luminosity, a salient idea is to adjust an image by adapting the contrast of an image according to a level of ambient light. Enhancing the contrast is known to make a displayed object more distinguishable, with some impact on the overall image quality. Increasing a level of contrast enhancement as the ambient light increases, advantageously allows to preserve distinguishable displayed objects in high levels of ambient light, despite an overall loss of quality, less perceivable in high levels of ambient light.

The method for displaying video frames on a display screen coupled to a portable video capturing device comprises displaying on the display screen, the video frames and a visual indicator indicating the orientation of the portable video capturing device in case where the orientation of said portable video capturing device is portrait or upside down landscape with respect to a reference orientation of said portable video capturing device and were said portable video capturing device is capturing at least one video frame.

Abstract: A method for selection of shots represented by identifiers displayed in a navigation menu. A document is divided into shots. Several attributes such as the moment of appearance of the shot in the document are assigned to each shot. The navigation menu disposes the identifiers according to a first axis according to the moment of appearance of the associated shot and according to a second axis according to the value of a second attribute according to a criterion other than the moment of appearance. A third attribute is determined for each shot according to a criterion other than the two first criteria, the shot identifiers having the same value as this third attribute are connected graphically. In this way the user perceives the value of several attributes associated with each shot and can easily select the shot that interests him. A display device able to display the navigation menu.

Abstract: A method and a TV receiver for updating child protection information in an IPTV system are suggested. The suggested method switches through all receivable TV channels, searches for child protection information and stores such information together with the associated TV channel number in a memory. If the user switches to a new TV channel then as a first step it is checked if for the newly selected TV channel child protection information is stored and if it is within a predefined allowed range. In this way adolescent users are effectively protected against offensive content.

Abstract: Fully scalable encoder and decoder for interlaced video. A method for encoding an interlaced sequence of digital video data decomposes the interlaced video sequence into first and second fields, performs digital filtering to get lower frequency and higher frequency component signals of the first fields, and uses spatio-temporal filtering and motion estimation for generating base layer signals being suitable for reconstruction of a progressive mode video sequence in a receiver. Advantageously, both the spatio-temporal filter at the encoder, and the inverse process at the receiver, can perform scaling in spatial and temporal dimension. The second fields are used to generate enhancement signals, which enable a receiver to reproduce an interlaced video sequence of the full, or scaled, spatial and/or temporal resolution.

Abstract: An encoding method applied to an input video sequence corresponding to successive scenes subdivided into successive video object planes (VOPs) is provided that generates, for coding all the video objects of said scenes, a coded bit stream the content of which is described in terms of separate channels and constituted of encoded video data in which each data item is described by a bitstream syntax that allows the recognition and decoding of all the elements of the content. The syntax comprises an additional syntactic information provided for describing independently the type of temporal prediction of the various channels. The additional information is a syntactic element placed at the slice level or the macroblock level in the coded bitstream, and its meaning is either specific for each present channel or shared by all existing channels.
