Generating and Evaluating Video Data in Car Infotainment Systems

Goepel Video Dragon15 July 2016 - Goepel electronic launched a functional test solution for high-speed LVDS connections and HDMI interfaces. It opens up new possibilities for quality test of infotainment systems. The Video Dragon combines frame grabber and frame generator in a single stand-alone device.

Utilized as a frame grabber, Video Dragon is able to record and analyze single images and video sequences in raw-data format or as compressed files. The frame rate includes up to 60 images per second at a maximum color depth of 24 bits. The concomitant unadulterated video output occurs at the output port, so the Video Dragon can easily be connected to two UUTs. Utilizing a serializer in the module port, Video Dragon turns into a frame generator capable of generation and transmission of single images, image sequences and video streams to a target device to be tested.

A wide range of serializer/deserializer modules are available, e.g. for the standards APIX 1 and 2, FPD-Link I/II/III or HDMI. Both STP and coaxial connectors are available. The Video Dragon can be integrated into complex test environments for infotainment components via the host interfaces Ethernet, GigE, USB 2.0 or 3.0 that are available in parallel.

Because most terminal equipment in the automotive sector has separate communication interfaces for device function control, Video Dragon provides respective CAN and LIN ports to turn on and off an ECU to be tested or adjust display brightness etc. Video Dragon supports communication through various interfaces, both as master and slave device.
