Automotive systems and devices must meet ever-increasing demands for performance, reliability and safety. To keep up with these requirements, developers need a comprehensive solution that can handle the complexity of modern automotive architectures. Our AVB and TSN solutions combined with EveryIP Framework provide just such an answer – a complete suite of technologies to help create state-of-the art automotive systems. All components are available off the shelf for mass production purposes making Cetitec solutions ideal for any project or application.
An overview of the Cetitec AVB infotainment solution, including audio and video streaming and control, is shown in the block diagram below. The streaming software components implement audio and video streaming according to IEEE1722 and/or IEEE1733, time synchronisation according to IEEE 802.1AS and stream reservation according to IEEE 802.1Q, if required.
Audio and video content delivered by AVB mechanisms is presented to application programmers via standard APIs such as ALSA and V4L2, allowing seamless integration with popular media player applications (web browsers, GStreamer, PulseAudio, MPlayer).
The control software components provide Diagnosis over IP (DoIP), Remote Procedure Call and Service Discovery functionality according to the SomeIP specification. The EveryIP framework provides all remote procedure call and payload encoding/decoding functionality, as well as service propagation and discovery, and the Integra code generator generates the stub code as the basis for implementing the business logic.
CETITEC‘s AVB Reference Infotainment System consists of the following devices:
