Embodiment Construction

[0037]Figure 1 is a general flowchart of the steps for selecting a sequence and playing back or recording a sequence. According to a preferred exemplary embodiment, the method comprises 5 steps. In a first step - step 1.1, an audiovisual file is generated. This audiovisual file is a digital image data file, possibly associated with a sound component. The image is advantageously animated (animate), but the file could also consist of photographs. In a second step - step 1.2, the file is stored in an easily downloadable form. This file is then processed by subdividing into sequences - step 1.3. At least two analysis techniques are implemented to generate two sets of sequences, each with specific selection criteria. Then, in step 1.4, the file is downloaded to the display device and the user enters selection criteria according to the two analysis techniques previously used. Then, two sequence subgroups are generated, each sequence subgroup is extracted from the previously gen...

Abstract

The invention concerns a method for selecting parts of an audiovisual programme. First, the document is analyzed using at least two segmenting means to extract at least two groups of audiovisual sequences. Then, selection criteria associated with each of the two segmenting means are introduced. Finally, a list of sequences fulfilling the set of selection criteria previously introduced is prepared. In accordance with one improvement, the sequences are concatenated based on a chronological order so as to prepare an audiovisual document representing the audiovisual document. The invention also concerns an apparatus for viewing the sequences selected in accordance with the method.

Description

technical field [0001] The invention relates to a method for selecting and replaying a video sequence extracted from a video file, and a device for implementing the method. The invention applies in particular to the case of selecting a video sequence from several extraction means that can be activated by the user. Background technique [0002] The context of the present invention is about extracting video sequences from video files. Nowadays, so many video files are produced that classification and segmentation in a manual way is no longer possible, so it is important to develop robust tools for automatic analysis of these contents. Various automated techniques exist for segmenting video files. One purpose of segmenting a video file is to extract the best moments of the file and provide a summary to the user by concatenating these best moments. The field of sports events especially requires a video content analysis device. The analysis devices can be adapted to each spor...
