Abstract: Aspects of the disclosure are directed to rotation of the graphics layer in video application. In accordance with one aspect, the apparatus includes a memory configured for storing a video layer in a compressed format and the graphics layer in an uncompressed format; and a display processing unit (DPU) coupled to the memory, the DPU configured for converting the graphics layer into an original compressed graphics layer, and for performing a graphics rotation on the original compressed graphics layer for generating a rotated compressed graphics layer. And, the method for rotation of a graphics layer includes converting the graphics layer into an original compressed graphics layer using a processing engine; and generating a rotated compressed graphics layer by using the processing engine to perform a graphics rotation on the original compressed graphics layer.
