Abstract

There is provided a multimedia computing apparatus for processing and displaying video data with overlay graphic data, said multimedia computing apparatus comprising a compression unit arranged to compress graphic overlay data prior to storage of said compressed overlay graphic data in a compressed display buffer, and a control unit arranged to determine when to compress the overlay graphic data dependent upon a refresh parameter of the overlay graphic data. There is also provided a method of adaptively compressing graphics data in a multimedia computing system comprising dynamically controlling compression of graphic overlay data in a display buffer dependent upon a refresh parameter of the graphic overlay data.
