Method to customize an application associated with a television experience based on the recognition of users located in front of a display and in the field of view of a camera, comprising the following steps: While subsequent identification is requested by the application, the following steps are executed

Method and device to speed up face recognition

A method, system, device, and/or a non-transitory computer readable medium to provide a customized application associated with a television experience based on the recognition of users located in front of a television display and in the field of view of a camera. The method may include performing an initializing operation, the initializing operation including enrolling a plurality of users in a database of a computer system, acquiring a wide image using the camera and scanning the wide image for biometric information; and performing an identification operation requested by the application including, acquiring a second wide image with the camera, extracting an active area from the second wide image, storing the extracted active area as a second fast scanning area image, and extracting the biometric data of a face appearing in the second fast scanning area image.

The present invention proposes a method to mark and exploit at least one sequence record of a video presentation played on a multimedia unit, said method comprising the steps of: during the video presentation, receiving a command from a user to mark a currently displayed video sequence, said command initiating the step of: creating a sequence record comprising a time index or frame index, allowing to locate the proper part of the video presentation, and a reference of the video presentation. At a later stage, requesting the edition of the sequence record by: adding textual information which corresponds to the actual sequence, and storing the sequence record.

Method to mark and exploit at least one sequence record of a video presentation

Method to customize an application associated with a television experience based on the recognition of users located in front of a display and in the field of view of a camera, comprising the following steps: &#x2014;an initialization step during which each user is enrolled in a database of a computer system and is defined by a profile referenced by a profile ID and comprising the user name, biometric data and additional personal data, &#x2014;a finding step during which a wide image, acquired by said camera is scanned to isolate at least one user's faces, to define a marking area surrounding it, to memorize the position of said marking areas, &#x2014;a matching step to extract the biometric data from said marking area, to match them with the biometric data of the profiles stored in the database, and to assign the detected profile ID with the marking area. While subsequent identification is requested by the application, the following steps are executed &#x2014;acquiring a wide image with the camera, &#x2014;extracting the areas of said image according to the marking areas, &#x2014;extracting for a particular marking area the biometric data of a face, &#x2014;starting the comparison of the extracted biometric data with the biometric data of the profile ID related to this marking area, and in absence of match, continuing with the other biometric data of the database until one profile is found, &#x2014;transmitting the found profile ID to the application.

The invention relates to a method for reception of a data stream, transmitted in segment in one or several broadcast channels, comprising a reception step for the data in a segment of data stream transmitted by an active broadcast channel. A step for changing reception channel allows switching from the current broadcast channel to a second channel after receipt of the data stream. A listening step on said second channel listens for an event identifying the transmission of the subsequent segment of the data stream and a step for changing reception channel by switching from said second channel to the current broadcast channel or another broadcast channel.
