First Claim
Patent Images
1. A method of storing data in at least one track of amultimedia file comprising:
- associating each track with at least one relative timebase indicator, as a function of an absolute timebase indicator;
determining at least some of time values contained in a respective track relative to a respective relative timebase indicator associated with said track; and
storing said data in said multimedia file comprising the absolute timebase indicator, said at least one relative timebase indicator, and said least one track in which said data is stored, said data comprising said time values including said determined at least some of the time values, wherein the relative timebase indicator is an indicator of a timebase common to the at least some time values in the track, wherein the absolute timebase indicator is an indicator of a timebase common to all time values in the multimedia file, and wherein the determining comprises determining duration of said at least some time values in the track based on the relative timebase indicator.

Abstract
The invention concerns a method for storing data in a multimedia file, the multimedia file containing an absolute time base indicator and at least a track wherein the data are stored. Said data comprise time values. The method is characterised in that it consists in associating with each track; at least a relative time base indicator which is a function of said absolute time base, and in determining some or all the time values contained in a track, with respect to a relative time base indicator associated with said track.

9. A method of storing data in at least one track of a multimedia file comprising:
-
generating one relative timebase indicator for each track, wherein the relative timebase indicator is a function of an absolute timebase indicator, storing, in each track, a respective generated relative timebase indicator; determining at least some of time values contained in a respective track relative to the relative timebase indicator associated with said track; and storing said data in said multimedia file comprising said absolute timebase indicator and said least one track in which said data is stored, said data comprises said determined time values, wherein the relative timebase indicator is an indicator of a timebase common to the at least some time values in the track, wherein the absolute timebase indicator is an indicator of a timebase common to all time values in the multimedia file, and wherein the determining comprises determining duration of said at least some time values in the track based on the relative timebase indicator. - View Dependent Claims (10, 11, 12, 13, 14)
