(EN) ADAPTIVE CODING AND STREAMING OF MULTI-DIRECTIONAL VIDEO

Abstract
(EN)
In communication applications, aggregate source image data at a transmitter exceeds the data that is needed to display a rendering of a viewport at a receiver. Improved streaming techniques that include estimating a location of a viewport at a future time. According to such techniques, the viewport may represent a portion of an image from a multi-directional video to be displayed at the future time, and tile(s) of the image may be identified in which the viewport is estimated to be located. In these techniques, the image data of tile(s) in which the viewport is estimated to be located may be requested at a first service tier, and the other tile in which the viewport is not estimated to be located may be requested at a second service tier, lower than the first service tier.

Dans des applications de communication, des données d'image source d'agrégat au niveau d'un émetteur dépassent les données qui sont nécessaires pour afficher un rendu d'une fenêtre d'affichage au niveau d'un récepteur. Des techniques de diffusion en continu améliorées consistent à estimer un emplacement d'une fenêtre d'affichage à un instant futur. Selon de telles techniques, la fenêtre d'affichage peut représenter une partie d'une image d'une vidéo multidirectionnelle à afficher à l'instant futur, et un ou plusieurs pavés de l'image peuvent être identifiés, dans lesquels il est estimé que la fenêtre d'affichage est située. Dans ces techniques, les données d'image du ou des pavés dans lesquels il est estimé que la fenêtre d'affichage est située peuvent être demandés au niveau d'un premier niveau de service, et l'autre pavé dans lequel il est estimé que la fenêtre d'affichage n'est pas située peut être demandé à un second niveau de service, inférieur au premier niveau de service.
