Title
(EN) SEPARATION OF GRAPHICS FROM NATURAL VIDEO IN STREAMING VIDEO CONTENT
(FR) SÉPARATION DE GRAPHIQUES À PARTIR D’UNE VIDÉO NATURELLE DANS UN CONTENU VIDÉO EN DIFFUSION CONTINUE
Abstract
(EN) Aspects of the subject disclosure may include, for example, a method that includes obtaining, by a processing system including a processor, video frames over a network; the processing system uses a machine learning algorithm to identify in each frame a first region comprising a natural image and a second region comprising a synthetic graphic image. The processing system separates the natural image from the synthetic graphic image to generate a natural video and a graphics video, encodes the natural video, and processes the graphics video to generate instructions for rendering graphic images at a client system. The client system performs a decoding procedure for the encoded video, a rendering procedure for client-side graphics in accordance with the instructions, and a compositing procedure to obtain a presentable video stream including the natural image and a client-side graphic corresponding to the synthetic graphic image. Other embodiments are disclosed.
(FR) La présente invention, selon certains aspects peut comprendre, par exemple, un procédé qui comprend l’obtention, par un système de traitement comprenant un processeur, de trames vidéo sur un réseau; le système de traitement utilise un algorithme d’apprentissage automatique pour identifier dans chaque trame une première région comportant une image naturelle et une seconde région comportant une image graphique synthétique. Le système de traitement sépare l’image naturelle de l’image graphique synthétique pour générer une vidéo naturelle et une vidéo graphique, code la vidéo naturelle, et traite la vidéo graphique pour générer des instructions destinées à restituer des images graphiques au niveau d’un système client. Le système client effectue une procédure de décodage de la vidéo codée, une procédure de rendu de graphiques côté client selon les instructions, et une procédure de composition pour obtenir un flux vidéo pouvant être présenté, incluant l’image naturelle et un graphique côté client correspondant à l’image graphique synthétique. D’autres modes de réalisation sont décrits.
