Abstract: A system and method for a operating a content distribution system includes a destination device and a requesting device that communicates a primary audio stream secondary audio stream and a video stream to the destination device. The destination device communicates the primary audio stream to a display. The destination device includes a secondary decoder configured to decode the secondary audio stream to form a decoded secondary audio stream. The destination device combines the secondary decoded audio stream and the primary audio stream.

Abstract: A system and method for controlling a communication system includes a local area network, a first client device and a first server device in communication with the first client device through the local area network. The first server device communicates an audio-visual stream and remote user interface data to the first client device through the local area network. The first client device renders a display using the audio-video stream and the remote user interface. The first client device generates a key command and communicates the key command to the first server device in response to the remote user interface data.

Abstract: 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.

Abstract: 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.
