Device and method for time-shifted playback of multimedia data
The invention relates to a method and a device for time-shifted playback of audio/video data. The device comprises: means of storing audio/video data received, means of recording said audio/video data received on said storage means, means of displaying said audio/video data received as it is recorded, means of pausing at a given time the display of said audio/video data while continuing to record it. According to the invention, on switching back to playback mode, said display means display a summary of the audio/video data received during the pause before resuming the playback of said audio/video data received in real time.
1. Device for time-shifted playback of audio and/or video data comprising:
means of storing audio and/or video data received,
means of recording said audio and/or video data received on said storage means,
means of displaying said audio and/or video data received as it is recorded,
means of pausing at the display of said audio and/or video data while continuing to record the audio and/or video data,
means of triggering the creation of a video summary of the audio and/or video data received during said pause upon detection of a user initiated pause; and
means of marking the audio and/or video data before it is recorded so as to identify the audio and/or video data forming the summary and to detect a start and end of the audio and/or video data to be retained in the summary by analyzing the content of the audio and/or video data;
wherein upon switching back to playback mode from pause mode, said display means displays said summary of audio and/or video data before resuming the playback of said audio and/or video data being received in real time.
2. Device according to claim 1 , wherein the means of creating said summary determines and extracts important representative moments from the audio or video data.
3. Device according to claim 1 , wherein the means of creating said summary mark the audio and/or video data before the audio and/or video data is recorded so as to identify the audio and/or video data forming the summary.
4. Device according to claim 2 , wherein the means of creating said summary create a file containing the audio and/or video data corresponding to the determined representative moments of the audio and/or video data recorded while the display is stopped.
5. Device according to claim 1 , wherein the means of creating said summary detect the end of data to be retained in the summary by analysing the video data and detect the start of the data to be retained by analysing the video data.
6. Method for time-shifted playback of audio and/or video data in a recording and display device comprising storage means, comprising steps for:
storing the audio and/or video data received,
recording the audio and/or video data received on said storage means,
displaying the audio and/or video data received as it is recorded,
pausing at a given time the display of the data while continuing to record the data,
detecting the pause initiated by a user, and in response to said detection, triggering the creation of a video summary of the audio and/or video data received during said pause;
marking the audio and/or video data before it is recorded so as to identify the audio and/or video data forming the summary and to detect a start and end of the audio and/or video data to be retained in the summary by analyzing the content of the audio and/or video data;
wherein upon switching back to the playback mode, displaying said video summary before resuming the playback of the data received in real time.
