Title (EN) USING HEADSET MOVEMENT FOR COMPRESSION
(FR) UTILISATION D'UN MOUVEMENT DE CASQUE POUR UNE COMPRESSION
Abstract:
(EN) A method at a host device (11) for compressing display data forming an image for display on one or more displays (19) of a wearable headset (12), such as a virtual or augmented reality headset. The method involves receiving from the wearable headset (12), information regarding movement of the wearable headset (12). If the movement is sufficient, all or some of the display data is compressed. The compressed data may form a trailing portion of the image relative to a leading portion as the headset (12) moves on an arc and may be of any size smaller than the whole image and may change in size on a frame to frame basis. The display data forming the image is then forwarded from the host device (11) to the wearable headset (12) for display on the one or more displays (19).
(FR) L'invention concerne un procédé au niveau d'un dispositif hôte (11) permettant de compresser des données d'affichage formant une image pour un affichage sur un ou plusieurs dispositifs d'affichage (19) d'un casque portable (12), tel qu'un casque de réalité virtuelle ou augmentée. Le procédé consiste à recevoir, en provenance du casque portable (12), des informations concernant le mouvement du casque portable (12). Si le mouvement est suffisant, l'ensemble ou un partie des données d'affichage est comprimée. Les données compressées peuvent former une partie arrière de l'image par rapport à une partie avant lorsque le casque (12) se déplace sur un arc et peut être de n'importe quelle taille plus petite que la totalité de l'image et peut changer de taille sur une base de trame en trame. Les données d'affichage formant l'image sont ensuite transmises du dispositif hôte (11) au casque portable (12) pour un affichage sur le ou les dispositifs d'affichage (19).
