Abstract
The present invention relates to a method for play back a digitized video streams at different fast forward speed levels, wherein at least one speed level is adapted so that a remaining portion of the stream is played back within a predefined time interval, and to a playback device for playing back a digitized video streams at different speed levels.
Claims11
Method for play back of a digitized video stream at different fast forward speed levels, comprising the steps of:
- providing a user with options to select at least one predefined fast forward mode and an adaptive fast forward mode;
- in response to receiving a user-selection of the adaptive fast forward mode, checking the remaining play back time of the currently played back complete recording, exceeds a predefined fixed duration,
- in response to confirming that the remaining play back time exceeds the pre-defined fixed duration, determining, by referencing the predefined fixed duration, a fast forward speed that constrains a duration of a play back of the remaining part of the recording to be within the predefined fixed duration and dynamically modifying a speed of the adaptive fast forward mode to the determined fast forward speed, and
- playing back at least a first part of the remaining part of the recording in the adaptive fast forward mode;
- in response to confirming that the remaining play back time is below the pre-defined fixed duration, keeping the speed of the adaptive fast forward mode unchanged.
