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.

The present disclosure relates to methods and apparatus for display processing. The apparatus can determine at least one data parameter corresponding to each of a plurality of layers in a display frame. The apparatus can also calculate a model for the at least one data parameter corresponding to each of the plurality of layers. Additionally, the apparatus can modify the model for the at least one data parameter based on one or more application use cases of the display frame. Moreover, the apparatus can implement the modified model on each of the plurality of layers in the display frame. In some aspects, the apparatus can also determine one or more composition settings for each of the plurality of layers based on the modified model. The apparatus can also apply the one or more composition settings to each of the plurality of layers based on the modified model.

An interactive flyer system is disclosed. The system includes a flyer image tiler for creating a flyer image tile set, the set including multiple copies of a flyer image segmented into a plurality of flyer image tiles with each copy representing the flyer image at one of a plurality of zoom levels, wherein a copy of the multiple copies is configured to fit within a viewport having a resolution, and a flyer image tile store for storing the flyer image tile set. There is also disclosed a method for displaying the interactive digital flyer.

For example, one embodiment of an apparatus comprises: a command streamer to queue commands from a plurality of virtual machines (VMs) or applications, the commands to be distributed from the command streamer and executed by graphics processing resources of a graphics processing unit (GPU); a tile cache to store graphics data associated with the plurality of VMs or applications as the commands are executed by the graphics processing resources; and tile cache allocation hardware logic to allocate a first portion of the tile cache to a first VM or application and a second portion of the tile cache to a second VM or application; the tile cache allocation hardware logic to further allocate a first region in system memory to store spill-over data when the first portion of the tile cache and/or the second portion of the file cache becomes full.

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.

Systems and methods of processing and streaming a virtual reality video using a graphics processing unit (GPU) are provided. A video server is configured to cause a processor to read, from a video data source, source video data including multiple spherical image frame data and store the source video data in a first memory. The video server is further configured to cause the GPU to convert, in response to storing first spherical image frame data in a first frame buffer of a second memory, the first spherical image frame data to first equirectangular image frame data that correspond to a portion of spherical image represented by the first spherical image frame data, encode the converted first equirectangular image frame data and store the encoded first equirectangular image frame data in an encoded frame buffer of the second memory.

The technology may conduct data formatting, re-projection, foveation, tile binning and/or image warping operations with respect to a plurality of display planes in a light field display.

Embodiments of the disclosure provide a display method, a display device, an electronic device and a computer readable storage medium. A plurality of second image data groups are obtained by performing color separation and sorting on the first image data of each layer pixel according to color information. Each of the second image data groups is synthesized, so as to obtain a plurality of synthesized layer data for the plurality of colors, and the plurality of synthesized layer data are sequentially displayed in the preset order of the colors.

A display control method includes: obtaining a delay instruction from a processor, in which the delay instruction includes a delay duration required to display a current image frame; determining a plurality of control pulses required to display the current image frame according to the delay duration, in which duty cycles of the plurality of the control pulses are identical; and when a synchronization signal is received, generating each of the plurality of the control pulses sequentially, in which the control pulse is configured to control an active-matrix organic light-emitting diode (AMOLED) display for dimming and displaying.
