Abstract: A vehicular vision system includes an ECU disposed at a vehicle and a front camera having a CMOS imaging sensor operable to capture image data. Image data captured by the imaging sensor of the front camera is conveyed from the front camera to the ECU via a single core coaxial cable. The front camera is in bidirectional communication with the ECU over the single core coaxial cable. The single core coaxial cable commonly carries (i) image data captured by the imaging sensor for processing at a data processor of the ECU and (ii) power from a DC power supply of the ECU to the front camera. Image data captured by the imaging sensor is serialized at a data serializer of the front camera and is transmitted to the ECU via the single core coaxial cable and is deserialized at the ECU by a data deserializer of the ECU.

Abstract: An apparatus and a method for bundling two data channels via a point-to-point connection, is described herein. Sequences of data from a first data channel are transmitted via a first line and sequences of data from a second data channel are transmitted via a second line to a multiplexing apparatus. A data gap having a predefined size is arranged between two sequences of first data in each case. The data from the second data channel are transmitted to a buffer and, if the buffer has been filled with second data having a predefined size, are inserted into the data from the first data channel. A third data channel is formed at the output of the multiplexing apparatus using these first data and second data and is transmitted to a third line. The third data channel therefore has a bundling of sequences of first data and sequences of second data.

Abstract: Systems and methods for signal communication over an optical link are described. One aspect includes receiving a source CONFIG1 signal from a DP master device and a sink CONFIG1 signal from a sink terminal. The source and sink CONFIG1 signals are analyzed. It is determined whether a signal transmission mode is a DP protocol. For a DP protocol, a pair of source AUX signals is received from the DP master device. A pair of sink AUX signals is received from the sink terminal. Communication resource contention between the source and sink AUX signals is identified. A communication direction of the communication resources is transitioned to give the source AUX signals precedence over the sink AUX signals. The source AUX signals are transferred to the sink terminal via the communication resources. The direction of the communication resources is again transitioned. The sink AUX signals are transferred to the DP master device.

Abstract: A hybrid projector architecture combines steered light with unsteered light. In some embodiments the steered light is narrowband light and the unsteered light is broadband light. Splitting between the steered and unsteered light may be determined based on luminance level. For example, the unsteered light may contribute a large proportion of the light for luminance levels up to a threshold. The steered light may contribute an increasing proportion of the light as luminance values rise above the threshold.

Abstract: The present aspects relate to techniques of timing synchronization of audio and video (AV) data in a network. In particular, the techniques for a AV master to distribute AV data encoded with one or more time markers to a plurality of processing nodes. The one or more time markers may be indexed to a precision time protocol (PTP) time stamp used as a time reference. In one technique, the nodes extract the time markers to determine an offset value that is applied to a PLL to synchronize AV data packets at a distribution node or a processing node. In another technique the distribution node or the processing node determines the worst case path, which corresponds to a system offset value. The distribution node then reports the system offset value to the AV master, which in turn adjusts the phase based on the report.
