METHOD FOR PROCESSING DISPLAY DATA
First Claim
1. A method for processing display data, applied to a host of a virtual reality device, wherein the method comprises the steps of:
- dividing a display area of a head-mounted display into a central area and an edge area according to a field of view of the head-mounted display of the virtual reality device;
segmenting display data to be transmitted of each frame into first display data corresponding to the central area and second display data corresponding to the edge area, according to ranges of the central area and the edge area;
processing the first display data and the second display data respectively according to a preset first transmission factor and a preset second transmission factor, to obtain first transmission data and second transmission data, wherein a bandwidth occupied by the second transmission data is less than a bandwidth occupied by the first transmission data; and
sending the first transmission data and the second transmission data to the head-mounted display.

Abstract
A method for processing display data comprises: the host divides the display area into a central area and an edge area according to the field of view of a head-mounted display; segments each frame of the display data into first display data corresponding to the central area and second display data corresponding to the edge area; processes the first display data and the second display data according to a first transmission factor and a second transmission factor to obtain first transmission data and second transmission data and sends them to the head-mounted display; and the head-mounted display performs image reconstruction to the received first transmission data and second transmission data, to obtain the displayed image corresponding to the frame of display data, and outputs and display it.

8. A method for processing display data, applied to a head-mounted display of a virtual reality device, wherein the method comprises the steps of:
-
receiving first transmission data and second transmission data that are sent by a host of the virtual reality device, wherein a bandwidth occupied by the second transmission data is less than a bandwidth occupied by the first transmission data, and the first transmission data and the second transmission data are obtained by segmenting each frame of the display data according to ranges of a central area and an edge area to obtain first display data and second display data and then processing the first display data and the second display data by using a first transmission factor and a second transmission factor, wherein the central area and the edge area are obtained by dividing a display area of the head-mounted display according to a field of view of the head-mounted display; performing image reconstruction to the received first transmission data and second transmission data, to obtain a displayed image corresponding to the frame of display data; and outputting and displaying the displayed image. - View Dependent Claims (9)
