A video codec for real-time encoding / decoding of digitized video data with high compression efficiency, comprising a frame encoder receiving input frame pixels; a codec setting unit for setting and storing coding setting parameters; a CPU load controller for controlling desired frame encoding time and CPU loading; a rate controller for controlling frame size; a coding statistics memory for storing frequency tables for arithmetic coding of bitstream parameters and a reference frame buffer for storing reference frames. The frame encoder comprises a motion estimation unit, a frame head coding unit, a coded frame reconstruction and storage unit and a macroblock encoding unit. The macroblock encoding unit provides calculation of texture prediction and prediction error, transforming texture prediction error and quantization of transform coefficient, calculation of motion vector prediction and prediction error and arithmetic context modeling for motion vectors, header parameters and transform coefficients. The codec also includes a deblocking unit for processing video data to eliminate blocking effect from restored data encoded at high distortion level, which may be a part of encoder or decoder, an internal resize unit, providing matching downscaling of a frame before encoding and upscaling of decoded frame according to the coding setting parameters, and a noise suppression unit.

A method of identifying a trailer with a vehicle includes a step of transmitting a unique identifier with a wireless transmitter attached to the trailer. The wireless transmitter may be housed as part of a sensor module with a sensor that senses a parameter of the trailer for operating a trailer backup assist system. The housing of the sensor module may be adapted to be removably attached to the trailer. The unique identifier emitted by the wireless transmitter is received with a wireless receiver on the vehicle. After the unique identifier is recognized by a controller on the vehicle, a parameter of the trailer may be accessed for autonomously guiding the trailer along a desired backing path.

A video codec having a modular structure for encoding / decoding a digitized sequence of video frames in a multi-core system is described. The video codec comprises a memory unit; a multithreading engine. and a plurality of control and task modules organized in a tree structure, each module corresponding to a coding operation. The modules communicate with each other by control messages and shared memory. The control modules control all coding logic and workflow, and lower level task modules perform tasks and provide calculations upon receiving messages from the control task modules. The multithreading engine maintains context of each task and assigns at least one core to each task for execution. The method of coding / decoding comprises denoising, core motion estimation, distributed motion estimation, weighted texture prediction and error resilient decoding.

The dynamic, predictive information system and method assigns shipping assets (drivers-tractors-trailers) from carriers to transport orders by shippers. Computer databases hold shipping asset data. Specific transport orders are electronically joined to specific driver-tractor-trailer combinations. A search and sort routine produces resulting records based upon proximity, trailer type, proximity of the joined driver-trailer combination, carrier service region and pick-up and delivery date constraints. The sort is by price or performance indicators which are pre-selected shipper ranges matched to historical shipping data from carriers. The system books the carrier, the driver-tractor-trailer combination and the shipper to transport order with an electronic communications phase. In a truck lane scenario, the system joins a specific driver and a specific tractor and a non-specific trailer to a specific transport order. GPS data and electronic shipping document data from PDAs with the drivers is logged into the system and is viewable by the participants.
