Techniques are described for encoding and decoding digital video data using macroblocks that are larger than the macroblocks prescribed by conventional video encoding and decoding standards. For example, the techniques include encoding and decoding a video stream using macroblocks comprising greater than 16×16 pixels. In one example, an apparatus includes a video encoder configured to encode a coded unit comprising a plurality of video blocks, wherein at least one of the plurality of video blocks comprises a size of more than 16×16 pixels and to generate syntax information for the coded unit that includes a maximum size value, wherein the maximum size value indicates a size of a largest one of the plurality of video blocks in the coded unit. The syntax information may also include a minimum size value. In this manner, the encoder may indicate to a decoder the proper syntax decoder to apply to the coded unit.

Unmanned device interaction methods and systems

A system for performing multi-level video processing within a vehicle includes a pre-processing module for determining an encoding mode and enabling one or more levels of encoding based on the encoding mode. The pre-processing module further receives a video stream from a camera attached to the vehicle via a vehicular communication network and encodes the video stream based on the encoding mode to produce a packet stream output. The system further includes a video decoder for receiving the packet stream output and decoding the packet stream output in accordance with the encoding mode to produce a decoded video output.

Presented herein are inverse scan, coefficient prediction, inverse quantization and inverse transform system(s) and method(s). In one embodiment, there is presented a system for converting scanned quantized frequency coefficients to pixel domain data. The system comprises a first circuit and a second circuit. The first circuit converts scanned quantized frequency coefficients to pixel domain data, wherein the scanned quantized frequency coefficients encode video data in accordance with a first encoding standard. The second circuit converts scanned quantized frequency coefficients to pixel domain data, wherein the scanned quantized frequency coefficients encode video data in accordance with a second encoding standard.

Described herein is a method and system for motion estimation in a video encoder. There are two parts to the motion estimation. Coarse motion estimation generates a set of motion vectors for a current picture and at least one reference picture. Typically, coarse motion estimation operates on sub-sampled pictures. Fine motion estimation can refine coarse motion estimation results by searching interpolated video data in a region defined by the motion vectors from the coarse motion estimation.

In a video processing system, a method and system for dynamic selection of transform size in a video decoder based on signal content are provided. For high profile mode video decoding operations, inverse transform sizes may be selected from a 4×4 or an 8×8 inverse transform size based on a transform size syntax element generated by the encoding operation and transmitted as part of the encoded video information bit stream. A set of rules is defined for selecting the transform size based on a macroblock type and a size of the macroblock type of a received macroblock in a video decoder. Dynamic selection of transform size may be performed on intra-coded macroblocks, inter-coded macroblocks, and/or direct mode inter-coded macroblocks.

A video transmission system includes a transceiver module that receives a device parameter from a remote device and that transmits a video signal to the remote device. An edge device receives a video stream from a video source and that generates the video signal by adjusting the video stream in accordance with the device parameter.
