Abstract
(EN)
There are provided methods and devices for data processing, an electronic device and a storage medium. The method for data processing is applied to a terminal and includes: performing pixel encoding according to pixel values of three-dimensional (3D) video data to obtain pixel encoded data; and sending the pixel encoded data to a Mobile Edge Computing (MEC) server, the pixel encoded data being used by the MEC server to restore the 3D video data. Here, a data volume of the 3D video data before the pixel encoding is performed on the 3D video data is a first data volume, a data volume of the 3D video data after the pixel encoding is performed on the 3D video data is a second data volume, and the first data volume is greater than the second data volume.

La présente invention concerne des procédés et des dispositifs de traitement de données, un dispositif électronique, et un support de stockage. Le procédé de traitement de données est appliqué à un terminal et consiste à : exécuter un codage de pixels selon des valeurs de pixels de données vidéo tridimensionnelles (3D), pour obtenir des données codées de pixels ; et envoyer les données codées de pixels à un serveur Mobile Edge Computing (MEC), les données codées de pixels étant utilisées par le serveur MEC pour restaurer les données vidéo 3D. Un volume de données des données vidéo 3D antérieur à l’exécution du codage de pixels sur les données vidéo 3D est un premier volume de données, un volume de données des données vidéo 3D postérieur à l’exécution du codage de pixels sur les données vidéo 3D est un second volume de données, et le premier volume de données est supérieur au second volume de données.
