摘要:
A system and method for displaying graphics in a content distribution system includes a client device and a server device that communicates an allocate buffer command signal to the client device. The client device reserves an off-screen buffer having buffer identifier associated therewith and communicates a buffer response signal comprising the buffer identifier to the server device. The server device communicates a write command signal comprising graphics data and the buffer identifier to the client device. The client device stores the graphics data in an off-screen buffer in response to write command signal, transfers the graphics data from the off-screen buffer to an on-screen buffer and displays graphics corresponding to the graphics data on a display associated with the client device. A bit blit command may be used to transfer the graphics data from the off-screen buffer to the on-screen buffer.
