Audio Video Bridging (IEEE 1722)
Benefits
Maximize Your Product’s Potential
Enhanced Automotive and Safety Systems
TSN (Time Sensitive Networking) adds guaranteed latencies for automotive control functions & the ability to build redundant network paths for safety-critical communications. Excelfore AVB/TSN is AVNU certified, so you also get interoperability with other certified AVB/TSN devices.
Scalable Network Bandwidth and Dynamic Switching
Ethernet enables cost-effective in-vehicle bandwidth scaling from 10MB multi-drop to 10GB and beyond. It also brings dynamic network switching, network security and the ability to reach devices from the Cloud.
IP Addressing and Accessibility for CAN Buses
SOME/IP, DoIP, RTP, RTCP and UDS protocols from Excelfore bring your legacy systems forward into the age of the Software Defined Vehicle, integrating seamlessly into an Ethernet backbone to provide full cloud accessibility to your CAN based devices.
Key Features
Sharpen Your Competitive Edge
Grand Synchronization
AVB networks provide a grand master clock to enable network traffic and connected devices to precisely synchronize across the network
➤ Generalized precision time protocol (gPTP): IEEE 802.1AS-2020
Traffic Shaping, Stream Prioritization, Bandwidth Reservation, AV Sync
Key AVB protocols shape the network traffic to give priority to mission-critical data & build redundancy into networks in safety-critical domains:
➤ Transport Protocol: IEEE1722 (AVTP)
➤ Credit-based shaper: IEEE 802.1Qav / 802.1Qat
➤ AVDECC Support: IEEE1722.1
➤ Application specific configurations: 802.1BA
Use Case
Explore Our Innovative Application
Application 1
Infotainment, Instrument Clusters & Audio Amplifiers:
Enhanced Infotainment Clusters
AVB (Audio-Video Bridging) provides guaranteed bandwidth and synchronization for data streams.
High-definition video & audio contents now move seamlessly between digital devices with synchronization and no caching delays.
Application 2
Surround-View Camera Cluster
Protocol stacks from Excelfore helped a global automotive Tier-1 supplier to implement a surround-view camera cluster for a major European automaker. Four 100MB Ethernet AVB links were implemented, with “Talkers” pushing IEEE 1722 AVTP (AV Transport Protocol) streams from high resolution digital video cameras, which are then received by the “Listeners”.
IEEE 802.1AS gPTP (general Precision Time Protocol) is then used to synchronize the consolidated view with high precision. The solution was implemented in a small RTOS.
Drivers get an integrated view of all sides of their vehicle, effectively a “bird’s eye” perspective, to assist in precise handling of their vehicles when parking or navigating tight alleyways.
