AUTOMOTIVE

This is what a YouTube video looks like when we use the simple embedding option and paste the YouTube link in the text block of the visual editor. The biggest drawback is that at the end of the video YouTube lists a bunch of “suggested videos” that may or may not be associated with AVnu.

However, with a few extra steps and the use of the video player tool on WordPress we can remove the “suggested videos”. Although the video appears smaller the user can still click the full screen option. See sample below:

Vimeo is another third-party hosting site that we could use. The preview window has a different appearance and looks a little more professional in my opinion but removing the recommended videos at the end requires a PRO account which costs money while YouTube is free. A sample of an embedded Vimeo video is below:

AVnu Video

 

A simpler, more capable foundation

While data networks in vehicle are common, current solutions have limitations that are limiting new applications and scaling to meet market needs:

  • Limited bandwidth
  • No ability to mix and match speeds to optimize costs/bandwidth needs
  • Lack of precise timing
  • Limited vendor base
  • Many technologies lack standardized redundancy
  • Lack of security

 

The AVB/TSN Advantage

By utilizing AVB/TSN into the network, solutions can take advantage of

  • An open, interoperable standard with independent testing available.
  • Precise timing to support low-jitter media clocks and accurate synchronization of multiple audio/video or sensor streams.
  • Independent traffic classes allow the optimization of network resources
  • Bounded latency delivers assurance of timely packet deliveries
  • Extreme reliability including redundant clock master and data traffic
  • Industry best practices for secure access and transactions

 

USE CASES

Avnu_Diagrams_Auto_new1

The figure shows an example with two RSE displays showing the video playback of a DVD whilst the audio is transmitted on a totally separate path to the amplifier. Ethernet AVB allows all three to be precisely synchronized. The Head Unit can also transmit 8kHz alerts or voice to the amplifier on the same network without sample rate conversion.

 

Avnu_Diagrams_Auto_new2

The figure shows the scalability and flexibility that can be realized with a networked system. All camera and sensor data acquisition can be precisely synchronized to minimize stitching efforts. The ADAS units and HU can equally access the camera and sensor data.

 

Avnu_Diagrams_Auto_new3

A fully networked car allows access to all sensors and cross-domain communication. Control messages can flow with minimal latency. Network Redundancy used for critical vehicle backbone.
