Abstract

A data processing apparatus at a transmitter end has an output interface and a camera controller. The output interface packs a compressed multimedia data into an output bitstream transmitted via a camera interface. The camera controller refers to a compression characteristic of the compressed multimedia data to configure a transmission setting of the output interface over the camera interface. A data processing apparatus at a receiver end has an input interface and a controller. The input interface un-packs an input bitstream received via the camera interface into a compressed multimedia data. The controller configures a reception setting of the input interface over the camera interface in response to a compression characteristic of the compressed multimedia data. In addition, the data processing apparatus at the transmitter end may selectively enable a compression mode by checking the de-compression capability of the data processing apparatus at the receiver end.
