Abstract:
1. A method for processing content requests, the method comprising: obtaining a content request including a request for display data corresponding to a specification of color values and transparency values for a plurality of pixels, wherein each pixel has a specific color value and a specific transparency value, the specific color value and the specific transparency values defined by a number of bits of data, and wherein a format for a response to the content requests corresponds to a number of bits of data for color values and a number of bits of data for transparency values; generating a color palette corresponding to a selection of a subset of pixel color values found in the plurality of pixels within the requested display data, wherein a size of the color palette is determined by the number of bits for color values in the format for the response to the content request; for each pixel in the display, mapping an original pixel color value to a color value in the color palette; if the number of bits defining an original pixel transparency value is less than or equal to the number of bits for transparency values in the format for the response to the content request, appending the original transparency values to the mapping of pixel color values for each pixel in the display; and transmitting the color palette and the mapped color values and transparency values in response to the content request.
