Abstract
Methods, device and data stream are provided to generate, transmit and decode haptic data. The present principles generally relate to the domain of encoding haptic data. In particular, the present principles relate to a block-based structure for haptic data allowing to process chunks of data in parallel for scalable network distribution like streaming applications.
Claims16
A method for encoding haptic data of a haptic sequence, the method comprising:
- obtaining binary haptic data representative of haptic effects and metadata describing the haptic effects;
- decomposing the haptic effects in temporal events and frequency bands and grouping them in tracks;
- and
- encoding the tracks and the metadata in access units, the metadata comprising perception data pointing to a sub-set of tracks and experience data pointing to a sub-set of perception data.
A device for encoding haptic data of a haptic sequence, the device comprising a processor configured for:
- obtaining binary haptic data representative of haptic effects and metadata describing the haptic effects;
- decomposing the haptic effects in temporal events and frequency bands and grouping them in tracks;
- and
- encoding the tracks and the metadata in access units, the metadata comprising perception data pointing to a sub-set of tracks and experience data pointing to a sub-set of perception data.
A method for decoding haptic data of a haptic sequence, the method comprising:
- obtaining a set of tracks and metadata encoded in access units, the metadata comprising perception data pointing to a sub-set of tracks and experience data pointing to a sub-set of perception data;
- and
- accessing the experience data in tracks pointed by perception data associated with the experience data.
