Single-pair Ethernet is currently being deployed in automobiles over unshielded twisted pair (UTP) cable. Ethernet shows great promise as an in-vehicle networking technology for the connected car due to its ubiquity, tools, modularity, and IP support.
Although some infotainment display and camera-based advanced driver assistance system (ADAS) applications have introduced Ethernet to prove the technology, serializer/deserializer (SerDes) architectures (sometimes incorrectly called LVDS) typically are simpler, offer higher video quality, and are less expensive in these systems.
Let’s compare these two technologies in detail using a four-camera surround view application as an example.
Siano and Audiovox co-developed an in-car mobile DTV tuner that delivers Live Mobile TV content to rear-seat entertainment systems. The tuner, on display at the Audiovox Electronics booth at CES 2013, uses Siano’s ATSC-MH receiver chip and a software player. The product will be sold via Audiovox’s distribution channels, including 12-volt retailers and expeditors who service new car dealers in addition to their OE customers.
Audiovox Electronics Corporation (AEC) will produce a custom headrest system that brings full function Android technology through local hotspot Wi-Fi connection to their custom headrest, rear seat entertainment (RSE) product line.
“Consumer behavior is changing. People have their whole lives on a single device that they use for music, videos and sharing content and they don’t want to give that up just because they are in their cars,” said Tom Malone, President, Audiovox Electronic Corporation.
SMSC said Daimler AG has selected SMSC’s Kleer® wireless audio technology as part of the rear seat entertainment system for 2010 Mercedes-Benz E-Class and S-Class models, which also feature the MOST® multimedia networking standard.
The Mercedes-Benz E-Class and S-Class models are the first automobiles to implement Kleer technology, which transmits CD-quality digital wireless audio from two video screens on the back of the seats to multiple wireless headphones. Each screen can display different content and occupants can select which audio stream their headphones receive. Multiple occupants can share the same stream.
To meet the space, cost and performance challenges of sophisticated graphic systems, Fujitsu has integrated Inova Semiconductors GmbH’s APIX® high-speed serial interface into its graphics display controllers.

“For us, it is important to discuss these matters in an early phase with chip manufacturers. Thus, we can achieve more stability in the development process.” – Robert Isele, Director of Driver Information Systems, Display Technology at BMW
Fujitsu Microelectronics introduces graphics SoC for in-vehicle video, audio applications in the Americas
Fujitsu Microelectronics America, Inc. (FMA) has introduced the MB86R02 “Jade D” System on Chip (SoC), which incorporates the Fujitsu MB86296 “Coral” graphics processor unit (GPU) with a 32-bit ARM926EJ-S™ CPU core.
Based on the Fujitsu 90nm CMOS process technology, the MB86R02 is optimized for modular automotive display applications requiring high CPU performance and sophisticated 2D/3D graphics. Target applications include graphical dashboard systems, head-up display units, on-board navigation systems, and rear-seat entertainment systems.
The 2010 Volvo XC70 features an Internet-connected rear seat entertainment (RSE) system with Windows XP, Wi-Fi, and a 500GB hard drive. Demonstrated at the Chicago Auto Show, the RSEi-500™ will allow passengers to surf the Internet and download applications to personalize their Volvo to their lifestyle. Passengers can use the system’s touch screen to select video and download music. The RSEi-500 will also allow customers to connect their vehicle to their home computer and transfer video, audio, and other home data content to the vehicle’s onboard computer.
NetLogic Microsystems, Inc. said its ultra low-power Au1300® Alchemy® processor has been selected by LG Electronics for LG’s automotive infotainment solutions, which include built-in audio/video navigation for dashboard and rear-seat entertainment systems.
The LG infotainment solutions, launched in October 2009, feature a 7-inch WVGA LCD display, voice recognition, rear camera functionality, navigation capabilities, and rich media playback. Theyintegrate Bluetooth, an iPOD interface, USB2.0 and AM/FM radio functionality.
“NetLogic Microsystems’ Alchemy processors truly surpassed our expectations in terms of best-in-class processing performance and unmatched low-standby power, making it ideal for our next-generation automotive infotainment solutions,” said June Kim, vice president of research & development at LG Electronics’ Car Infotainment business. “We look forward to our continued close collaboration with NetLogic Microsystems.”

For years, rear seat entertainment has been thought of as a DVD player for car passengers. Most systems come as a box with a DVD drive and a display either attached to the player or separated; to be mounted on the passenger seat. These systems have evolved, adding wireless infrared or Bluetooth headphones. Codec support increased, adding features like MP3 or DviX decoding, but the main data sources of these devices are DVDs and CDs.
