Abstract
To synchronize sound information with corresponding picture information for digital cinema compositions at different frame rates in a play list during play out of the digital cinema compositions, associated audio latency settings are first established for the corresponding picture information of the digital cinema compositions in the play list in accordance with the digital cinema composition frame rates. The timing between the sound information and the picture information is then adjusted during play out of the digital cinema compositions in accordance with the associated audio latency settings for the corresponding digital cinema composition frame rates.
Claims19
A method for synchronizing sound information with corresponding picture information for contents having different frame rates in a play list during play out of the contents, the method comprising:
- establishing for the corresponding picture information of the contents in the play list, associated audio latency settings in accordance with the content frame rates;
- and
- adjusting timing between the sound information and the picture information during play out in of the contents in accordance the associated audio latency settings for the corresponding content frame rates.
In a system for presentation of contents in a play list, an apparatus for substantially synchronizing picture information and sound information for each content irrespective of a content frame rate, the apparatus comprising:
- media block for rendering contents received at their frames rates, the digital media block (a) establishing for the corresponding picture information of the contents in the play list, associated audio latency settings in accordance with the content frame rates;
- and (b) adjusting timing between the sound information and the picture information during play out in of the contents in accordance the associated audio latency settings for the corresponding content frame rates.
