Abstract: Method and system (100) for generating a recommendation for at least one further content item is disclosed. A personalized content channel is enabled to play out a plurality of content items (programs) complying with multiple selection criteria. At least one further content item is recommended by a recommender engine (107), the at least one further content item complying with fewer of the multiple criteria. In an embodiment, at least one of the at least one recommended further content item is selected and the multiple selection criteria are adjusted by a scheduler (109) on the basis of at least one characteristic of the selected recommended further content item.

Abstract: Items having a plurality of attributes associated therewith, each of said associated attributes having a rating, the rating indicating the importance of the attribute to the user can be selected (201) and displayed (205) with its associated attributes and corresponding ratings. The ratings can be adjusted (207) and at least one item similar to one of the selected at least one first item is selected (209) based on the rating of at least one of the displayed attributes.

Abstract: The recommender system uses stored representations of relations between users. Access to an item by one or more first users in the storage system is recorded. When the recommender system detects a request for a rating of the item from a second user, the recommender system selects at least one of the first users that occurs in a stored relation with the second user. A query message that refers to the second user is then automatically transmitted to enter a rating for the item to a user address associated with the selected first users. Preferably at least one first user is selected for which it has been recorded that it has accessed the item but for which it has not yet given a rating. Preferably, the rating from the first user is passed to the second user via the recommender system, which records the rating for further use. The selection of the first user may be based on recorded data that measures correlation between ratings from the first and second user.

Abstract: A recommender engine (107_1, 107_2, 107_3) recommends further content items for playout on a personalized content channel on the basis of a profile (109_1, 109_2, 109_3) associated with that personalized content channel. The profile (109_1, 109_2, 109_3) includes an indication of the user's “like” and “dislike” of content items played out on said personalized channel.

Abstract: Devices and methods for generating a three-dimensional video stream starting from a sequence of video images. The sequence includes a first view (V0), at least one second view (V1) of a scene, and a depth map (D0) of said first view (V0), or a disparity map of said at least one second view (V1) with respect to the first view (V0). At least one occlusion image (O1) including the occluded pixels of said second view (V1) is obtained by starting from said depth map (D0) or from said disparity map. A compacted occlusion image (OC1)is generated by spatially repositioning said occluded pixels of said at least one occlusion image (O1), so as to move said pixels closer to one another. The three-dimensional video stream may include said first view (V0), said depth map (D0) or said disparity map, and said at least one compacted occlusion image (OC1).

Abstract: A method for superimposing images on three-dimensional content, wherein a video stream is received which includes the three-dimensional content and a depth map for superimposing images on the three-dimensional content. Once the video stream has been received, images are superimposed on the three-dimensional content in a position in depth dependent on the superimposition depth map (DM). The superimposition depth map contains information about the depth of the three-dimensional content and is inserted as an image contained in a frame (C) of the video stream. The depth map has a smaller number of pixels than that of a two-dimensional image associated with the three-dimensional content. The invention also relates to devices enabling the implementation of the methods.
