Abstract: A data bridge controls packet transfers between network fabrics forming a closed network, such as a vehicular network and a home network. The data bridge includes two or more sets of modules, each of which communicates with a different network fabric. When a packet is to be delivered between network fabrics, a first set of modules, which is used to communicate with a first network fabric, decides whether to accept the packet or discard it. If the packet is accepted, it is delivered to a second set of modules, which is used for communicating with a second network fabric. The second set of modules makes a second, independent decision about whether the packet will be sent to the second network fabric. Each set of modules can base its decision on packet content type, and may discard any packet not to be delivered to the other network.

Abstract: 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.

Abstract: A vehicle network node module includes device buffers, a network buffer, a switch circuit, and a processing module. The device buffers temporarily store outgoing device packets from, and temporarily store incoming device packets for, vehicle devices in accordance with a locally managed prioritization scheme. The network buffer receives incoming network packets from, and outputs the outgoing network packets to, a vehicle network fabric in accordance with a global vehicle network protocol. The network buffer also temporarily stores the incoming network packets and the outgoing network packets in accordance with the locally managed prioritization scheme. The switching circuit selectively couples the network buffer to individual ones of the device buffers in accordance with the locally managed prioritization scheme. The processing module interprets the outgoing device packets and the incoming network packets to determine types of packets and determines the locally managed prioritization scheme based on the types of packets.
