Sony patents file format to protect asynchronous media playback
Sony describes a method for storing video or audio data that plays back at different speeds or times. The system packs the data into a specific file format with extra information that helps the device play it correctly while preventing unauthorized copying.
In the filing’s own words
The present disclosure relates to an information processing apparatus and method that enable unauthorized reproduction of an asynchronous media to be suppressed. Media encoded data of an asynchronous media and asynchronous media information that indicates that media data is of the asynchronous media and requires parsing for reproducing the asynchronous media are stored in a container file. Further, the asynchronous media information is parsed, the media encoded data of the asynchronous media is decoded in accordance with a result of the parsing and a reproduction condition, media data obtained by the decoding is rendered to generate output information, and an output unit is caused to output the output information, as reproduction of the asynchronous media. The present disclosure can be applied to, for example, an information processing apparatus, an information processing method, and the like.
What exactly they claim (claim 1)
1. An information processing apparatus, comprising: an encoding unit which encodes media data of an asynchronous media to be reproduced asynchronously, to generate media encoded data; and a file generation unit which generates a container file and stores the media encoded data and asynchronous media information in the container file, wherein the asynchronous media information indicates that the media data is of the asynchronous media, and requires parsing for reproducing the asynchronous media.
