摘要:
A navigation system may include a positioning device for generating a position data signal, a geographical data storage device for generating a digital map data signal, a processing device for generating navigation information based on the position data signal and the digital map data signal, and a turn control device for generating output signals to activate and/or deactivate turn signals of the vehicle and/or to enable an autonomous vehicle control system to perform a driving maneuver. The turn control device may analyze the navigation information to detect when the distance to an approaching turn fails to exceed a predetermined limit or when the turn has been completed or bypassed. The turn control device may analyze the navigation information and a velocity data signal generated by a velocity sensing device to detect when the time to the approaching turn fails to exceed a predetermined limit.

A system that includes a talker, a listener, and a controller may communicate over an Ethernet Audio/Video Bridging network. The controller may communicate control messages to manage data streams between the talker and the listener through one or more application layer interfaces of the talker and the listener. Based on the control messages, the talker and the listener may communicate using a Stream Reservation Protocol to reserve connection for, or remove connection from, the data streams. The talker and listener may communicate the success of reserving or removing the connections to the controller through the application layer interfaces.

Media Clock Negotiation (MCN) Advertise packets may advertise one or more media clock streams. Each media clock stream may include values of a real-time clock sampled according to a first media clock. A second media clock may be recoverable from the media clock stream such that the second media clock is synchronized with the first media clock. One or more transmitters that receive the packets may determine whether the advertised media clock stream meets a set of media clock conditions. If the advertised media clock stream meets the set of media clock conditions, then the transmitter may add the advertised media clock stream to a set of qualified streams. Each transmitter may select a reference media clock stream from the set of qualified streams. By selecting the same reference media clock stream, media clocks at two or more transmitters may be synchronized.

A system that includes a transmitting apparatus and a receiving apparatus may communicate over an Ethernet Audio/Video Bridging network. The transmitting apparatus and the receiving apparatus may each include an application layer module in communication with an application interface module. The application layer module of the transmitting apparatus may interface with the application interface module to send a control message over the network to control flow of a data stream over the network. The application layer module of the receiving apparatus may interface with the application to interface module to receive the control message.

摘要:
A listener system, or listener, may be used with an Ethernet Audio-Video Bridging (“AVB”) network. The listener may include various components, such as an upper layer application and a stream reservation protocol stack. The upper layer application and stream reservation protocol stack may be in communication with each other. The stream reservation protocol stack may receive stream advertisements on or across the Ethernet AVB network. The stream reservation protocol stack may operate in a sparse mode and may operate in a full mode. When operating in a sparse mode, the stream reservation protocol stack may transmit one subset of the received stream advertisements to the upper layer application, and may not transmit another subset of the received stream advertisements to the upper layer application.
