Abstract: A method, device and non-transitory computer-readable medium for control of a refresh frequency of a display unit are disclosed. The display unit is in communication with a processor and configured to display image frames processed by the processor on a screen of the display unit. The method includes: acquiring a real-time frame composition frequency corresponding to an amount of time required for the processor to complete composition of an image frame to be displayed; determining a refresh frequency of the display unit based on the real-time frame composition frequency, when the real-time-frame composition frequency satisfies a preset condition; and refreshing the screen of the display unit at the determined refresh frequency.

Abstract: A video server is configured to convert frame data of a spherical image to frame data of a equirectangular image such that a first area corresponding to a field of view received from a client device is a middle area of the equirectangular image. The video server is further configured to scale the first area at a first resolution, scale a second area of the equirectangular image adjacent to the first area at a second resolution smaller than the first resolution, scale a third area of the equirectangular image that is adjacent to the first area and is not adjacent to the second area, at a third resolution smaller than the first resolution, and rearrange the scaled first area, second area and third area such that the scaled second area and the scaled third area are adjacent to each other, to generate reformatted equirectangular image frame data to be encoded.

Abstract: A system on chip includes a video codec configured to output syntax information and data information, which correspond to each of a plurality of blocks included in each frame of image data, based upon a result of encoding or decoding the image data. A map generator is configured to determine whether each of the blocks is an update block based upon the syntax information and to generate a mapping table based upon a determination result. A display controller is configured to output the mapping table and data information corresponding to the update block to a display device.

Abstract: The invention provides, in some aspects, a system for rendering images, the system having one or more client digital data processors and a server digital data processor in communications coupling with the one or more client digital data processors, the server digital data processor having one or more graphics processing units. The system additionally comprises a render server module executing on the server digital data processor and in communications coupling with the graphics processing units, where the render server module issues a command in response to a request from a first client digital data processor. The graphics processing units on the server digital data processor simultaneously process image data in response to interleaved commands from (i) the render server module on behalf of the first client digital data processor, and (ii) one or more requests from (a) the render server module on behalf of any of the other client digital data processors, and (b) other functionality on the server digital data processor.

Abstract: A display recording information and generation method thereof are disclosed. The display recording information is used to record the corresponding relationship between the display information received by a driving IC of a display and pixels of the display. The display recording information is formed by one byte (8 bits). Its first bit through six bit record a counting result that a number counter or a column counter performs a six-bit counting on a number of pixels or a number of columns of pixels starting from 0; its seventh bit uses 0 or 1 to record that the counting result belongs to the number of pixels or a number of columns of pixels; its eighth bit uses 1 to record that a most significant bit of the display information including red, green, or blue is 1, otherwise uses 0 to record.

Abstract: A method for composing a multilayer video image of which the values of the pixels of the image layers are stored in a memory. The video image may include at least one first image layer and a second image layer located in front of the at least one first layer and having an opaque area. The method may include defining a region of the at least one first image layer to be hidden by the opaque area, reading from the memory the stored pixel values, with the exception of the values of the pixels of the region of the at least one first image layer, and composing the video image at least from the read pixel values.
