Abstract
The present invention provides a video transmission system that comprises a camera and a base unit. The camera includes a sensor memory adapted to store video data until each line of the video data is sequentially transmitted, a data buffer adapted to receive and store the sequentially transmitted video data until it is completely received at a base unit memory without errors, a data port adapted to receive from the data buffer and transmit to a camera physical transceiver the data buffered video data, a controller adapted to control data flow between the camera and the base unit, and the camera physical transceiver adapted to transfer the data buffered video data to a physical transceiver of the base unit. The base unit includes the base unit physical transceiver adapted to receive the transferred video data, a base unit data port adapted to receive from the base unit physical transceiver and transmit to a data buffer of the base unit, the transferred video data, a controller adapted to control data flow between the base unit and the camera, the base unit data buffer adapted to store the transferred video data from the base unit data port until it is completely received at the base unit physical transceiver without errors, and the base unit memory adapted to receive and sequentially store each line of the transferred video data.
