摘要： A system and method for controlling closed-captioning at a client device includes a client device and a server device that communicates content to the client device. The server device determines a content type corresponding to the content communicated from the server device to the client device, generates a closed-captioning disable signal and communicates the content type disable signal to the client device. The client device disables the closed-captioning in response to the closed-captioning disable signal.

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.
