A device and a method for sharing resources in a network of peers are disclosed. A user may compile a wish list (420) of programs to be recorded on a recording device (400) that is a peer in the network. A resource list (421) is compiled of resources that the device shares within the network. The wish list and resource list are communicated to a coordinator (440) comprised within the network. The coordinator makes assignments of who records what and communicates an assignment list (422) to each peer. Each peer plans (405) and executes (407) the assigned recordings, which can be retrieved from a peer (410), or sent to the user device. Deletion control is applied to prevent the loss of recordings by deletion on a local peer. The coordinator may be comprised within a peer, as a standalone service within the network or implemented as a distributed algorithm between the peers.

The present invention enables combining personal media content and additional content with the purpose of generating a more appealing and engaging experience to the user when being presented the personal media content. The invention therefore relates to a method and a device for generating a multimedia presentation, comprising obtaining a user selection of a first media file (step 202), obtaining a user selection of a media file source (step 208), matching content associated data of the first media file, with content associated data of at least one second media file from the media file source (step 214), generating at least one user inquiry related to the content associated data of at least the first media file (step 216), and creating the multimedia presentation, based on the first media file and the at least one second media file, said multimedia presentation comprising the at least one generated user inquiry (step 218).

The present invention relates to a method of processing digital coded video data available in the form of a video stream consisting of consecutive frames divided into slices. The frames include at least I-frames, coded without any reference to other frames, P-frames, temporally disposed between said I-frames and predicted from at least a previous I- or P-frame, and B-frames, temporally disposed between an I-frame and a P-frame, or between two P-frames, and bidirectionally predicted from at least these two frames between which they are disposed. The processing method comprises the steps of determining for each slice of the current frame related slice coding parameters and parameters related to spatial relationships between the regions that are coded in each slice, collecting said parameters for all the successive slices of the current frame, for delivering statistics related to said parameters, analyzing said statistics for determining regions of interest (ROIs) in said current frame, and enabling a selective use of the coded data, targeted on the regions of interest thus determined.

Method and device for providing a summary of a plurality of images, e.g. a video sequence. The method includes dividing the video sequence into a plurality of segments. The segments are analyzed with respect to content and a set of content descriptors are associated to the segments. Preferably, additional textual information about the segments, screenplay etc., is used to determine the content descriptors. A graph representing relations between the segments is constructed indicating relations between segments. Weights are associated to the relations so as to represent a measure of relation, e.g. a logical correlation, between segments. The weights are based on the calculated content descriptors. A relevance measure for a segment is determined based on all weights associated with relations to said segment. Finally, a summary is generated by selecting the most relevant segments. The method can create an automatic summary of a film that preserves all the logical plot of the original but is shorter in duration (e.g. 70% of the original film) while the original playback rate is preserved.

A system and method augments a recorded lecture (110) based on the importance of the material and/or based on a student's needs. The importance of each segment of the lecture material (110) is based at least in part on questions from prior exams (120), and the student's needs are based at least in part on the student's performance (130) on prior exams. The method (410-440) of presenting the augmented material to the student may also be customized based on the student's learning style.

The invention relates to a detection method applied to digital coded video data available in the form of a video stream comprising consecutive frames divided into macroblocks themselves subdivided into contiguous blocks. These frames comprise I-frames, coded independently, P-frames, predicted from a previous I- or P-frame, and B-frames, bidirectionally predicted from at least two frames between which they are disposed. According to the invention, the processing method comprises the steps of determining for each block of the current frame if it has been coded, or not, according to a predetermined intra prediction mode, collecting similar information for all the blocks of the current frame, for delivering statistics related to said intra prediction mode, analyzing said statistics for determining the number of blocks of said current frame which exhibit, or not, said intra prediction mode, and detecting in the sequence of frames, each time said number is greater than a given threshold, the occurrence of an image, or a sub-region of an image, which is either monochrome or with a repetitive pattern.
摘要:
The invention describes a system (1) for generating audio-visual summaries for audio-visual program content (3). The system comprises a search unit (4) for locating a pre-generated text summary (5) associated with the program content (3); a speech synthesizer (6) for converting the text summary (5i) into speech (7); a video 5 summary generator (8) for generating a video summary (9) of the audio-visual program content (3), and an audio/video mixer (10) for mixing the synthesized speech (7) with the video summary (9). Moreover the invention describes an appropriate method for generating audio-visual summaries (5i) for audio-visual program content (3).

A user of a mobile client requests electronic content information for being downloaded via a data network. The client first receives a semantically summarized version of the requested content information. If the downloading is prematurely interrupted, the user has at least a meaningful summary available.

On a distributed data processing system, a history of file migration is maintained. When access to a file is requested and the file is not found, the migration history is consulted to determine the current location of the file, and to update links contained in other files that point to the request file.

The invention relates to a method of detecting a boundary of a content item in a digital video stream. The method comprises the steps of determining (130) an average bit rate of the video stream over a period of time, and detecting (140) a change of the average bit rate indicating the boundary of the content item. A moving average of the bit rate may be determined. The method can be used for an encrypted digital video stream. The invention also relates to a device for detecting a boundary of a content item in a digital video stream. The invention further relates to a receiver for receiving at least one content item in a digital broadcast video stream, and a video recorder for recording at least one TV program.
