  • Patent number: 11743366
    Abstract: A processor receives data corresponding to a sensor, and generates a frame having a header and a payload. A data type value is selected from a set of multiple data type values corresponding to different respective types of data, the set of multiple data type values including at least i) a first data type value corresponding to video data from a camera, and ii) a second data type value corresponding to non-video data. The header is generated to include one or more fields set to the selected data type value to indicate a type of data included in the payload, and the payload is generated to include the data received from the sensor. The processor provides the frame to an Ethernet network interface. The Ethernet network interface encapsulates the frame in an Ethernet packet, and transmits the Ethernet packet via an Ethernet link.
