Abstract
In a vehicular communication network, a processor receives a packet that includes data corresponding to a sensor, the packet being in a first format. The processor reformats the packet in the first format to a second format different than the first format. The reformatting of the packet includes the processor generating an intermediate frame that includes a header in the second format and a payload in the second format, the payload including the data corresponding to the sensor. The processor provides the frame to an Ethernet network interface, which encapsulates the frame in an Ethernet packet. The Ethernet network interface then transmits the Ethernet packet via an Ethernet link.
Claims22
A method for communicating in a vehicular communication network, the method comprising:
- receiving, at a processor, a packet that includes data corresponding to a sensor, the packet being in a first format defined by a camera serial interface (CSI) protocol of the Mobile Industry Processor Interface (MIPI) Alliance;
- reformatting, at the processor, the packet in the first format defined by the CSI protocol to a second format that does not conform to any CSI protocol of the MIPI alliance, the reformatting including:
- i) selecting, based on a first field in the packet in the first format, a data type value from a set of multiple data type values corresponding to different respective types of data, ii) generating an intermediate frame that does not include the packet in the first format, the intermediate frame being generated to include a header in the second format and a payload in the second format, the payload including the data corresponding to the sensor, and iii) generating the header to include one or more second fields set to the data type value;
- providing, by the processor, the intermediate frame to an Ethernet network interface;
- encapsulating, at the Ethernet network interface, the intermediate frame in an Ethernet packet;
- and
- transmitting, by the Ethernet network interface, the Ethernet packet via an Ethernet link.
A communication device, comprising:
- a processor configured to:
- receive a packet that includes data corresponding to a sensor, the packet being in a first format defined by a camera serial interface (CSI) protocol of the Mobile Industry Processor Interface (MIPI) Alliance,
- reformat the packet in the first format defined by the CSI protocol to a second format that does not conform to any CSI protocol of the MIPI alliance, the reformatting including:
- i) selecting, based on a first field in the packet in the first format, a data type value from a set of multiple data type values corresponding to different respective types of data, ii) generating an intermediate frame that does not include the packet in the first format, the intermediate frame being generated to include a header in the second format and a payload in the second format, the payload including the data corresponding to the sensor, and iii) generating the header to include one or more second fields set to the data type value, and
- outputting the intermediate frame to an Ethernet network interface;
- and
- an Ethernet network interface configured to:
- receive the intermediate frame output by the processor,
- encapsulate the intermediate frame in an Ethernet packet, and
- transmit the Ethernet packet via an Ethernet link.
