Methods for signaling random access in haptics interchange file format

An apparatus for decoding haptic data, the apparatus comprising:

• at least one memory configured to store program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code including:
• first receiving code configured to cause the at least one processor to receive haptic data in a Haptics JSON-based Interchange Format (HJIF) based on a JavaScript Object Notation (JSON) object;
• second receiving code configured to cause the at least one processor to receive a moving picture experts group (MPEG) haptics object associated with a global haptic experience, the MPEG haptics object in the haptic data in the HJIF comprising a plurality of reset point timestamps;
• rendering code configured to cause the at least one processor to render effects based on the haptic data in the HJIF;
• and
• resetting code configured to cause the at least one processor to reset an output of a renderer responsive to determining that a current timestamp associated with the global haptic experience is equal to a reset point timestamp in the MPEG haptics object.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of a device for decoding haptic data, cause the one or more processors to:
• receive haptic data in a Haptics JSON-based Interchange Format (HJIF) based on a JavaScript Object Notation (JSON) object;
• receive a moving picture experts group (MPEG) haptics (MPEG_haptics) object associated with a global haptic experience, the MPEG_haptics object in the haptic data in the HJIF format comprising a list plurality of sync reset point timestamps;
• render effects based on the haptic data in the HJIF;
• and
• reset an output of a renderer responsive to determining that a current timestamp associated with the global haptic experience is equal to a reset point timestamp in the MPEG haptics object.
