Title
(EN) PERSONALIZED VIDEO CLASSIFICATION AND RETRIEVAL SYSTEM
(FR) SYSTEME PERSONNALISE DE CLASSEMENT ET DE SAISIE VIDEO
Abstract
(EN)
A video retrieval system is presented that allows a user to quickly and easily select and receive stories of interest from a video stream. The video retrieval system classifies stories and delivers samples of selected stories that match each user's current preference. The user's preferences may include particular broadcast networks, persons, story topics, keywords, and the like. Key frames of each selected story are sequentially displayed; when the user views a frame of interest, the user selects the story that is associated with the key frame for more detailed viewing. This invention is particularly well suited for targeted news retrieval. In a preferred embodiment, news stories are stored, and the selection of a news story for detailed viewing based on the associated key frames effects a playback of the selected news story. The principles of this invention also allows a user to effect a directed search of other types of broadcasts as well. For example, the user may initiate an automated scan that presents samples of broadcasts that conform to the user's current preferences, akin to directed channel-surfing.

Cette invention concerne un système de saisie vidéo permettant à l'utilisateur de choisir rapidement et facilement, puis de recevoir des programmes vidéo d'intérêt. A partir de thèmes ordonnés, ce système de classement vidéo propose des échantillons d'histoires qui répondent aux préférences du moment de l'utilisateur. Ces préférences peuvent porter sur une chaîne de télédiffusion particulière, des personnes, des thèmes, des mots clés, etc. Pour chaque histoire sélectionnée, des trames marquantes sont affichées séquentiellement. Lorsque passe une trame qui l'intéresse, le téléspectateur choisit l'histoire dont est tirée cette trame pour la visionner plus en détail. Cette invention convient particulièrement bien pour la saisie de nouvelles ciblées. Selon un mode de réalisation préféré, on stocke des séquences de nouvelles, lesquelles sont sélectionnées et diffusées en fonction de trames tirées de ces séquences. De par ses caractéristiques, cette invention permet à l'utilisateur d'effectuer des recherches directes dans d'autres programmes. Celui-ci peut par exemple lancer une recherche automatique qui fait apparaître des échantillons de programmes conformes à ses préférences, comme s'il naviguait directement sur les canaux.
