ICs for ADAS & infotainment feature H.264 codec

According to IHS Technology, the automotive display market will grow exponentially over the next six years. Driver Information Displays (DIDs) are one of the fastest growing segments, with an expected increase from 30.8m units in 2014 to 102.8m  in 2020. Driven by safety requirements, the camera market in motor vehicles is also projected to explode. These predictions reflect the increasing demand for video content in all car classes.

Featuring a low-latency, high-quality H.264 codec and an on-chip Digital Transmission Content Protection (DTCP) coprocessor, the OS85621 enables automotive designers to implement a comprehensive content-protected video transmission solution within days. Video streams with restricted access from devices such as DIDs, digital media drives and TV tuners can now be easily transmitted as encrypted H.264 over a MOST network, satisfying today’s market demand for high-quality audio and video within the automotive environment.

The OS85621’s on-chip DTCP coprocessor supports hardware acceleration of the computation-intensive operations required for DTCP authentication and content protection. Up to eight independent data streams can be simultaneously routed through the DTCP coprocessor’s cypher engine for M6 or AES-128 encryption/decryption.

The ultra-low-latency mode of the H.264 codec enables single-digit millisecond latency from video input to video output, including encoding, transmission over a MOST network and decoding. This real-time, high-speed video processing makes the OS85623 suitable for camera-based ADAS applications designed to enhance vehicle safety.

Both devices feature a number of hardware interfaces commonly used for infotainment data exchange.

The devices' video-interface ports support a variety of industry-standard formats and resolutions, including HD for seamless interfacing to video sources. A streaming port supports legacy audio formats and 7.1 multi-channel audio up to 24 bits. Two independent, inter-chip-communication Media Local Bus (MediaLB) ports provide a seamless interface to Microchip’s Intelligent Network Interface Controllers (INICs) for MOST networks, as well as application processors. These video I/O companion chips also feature an additional Transport Stream Interface for compressed video streams.

To ensure compatibility with other DTCP devices and further reduce development efforts, Microchip also offers its free and ready-to-use DTCP-Stack for I/O Companions. Additionally, Microchip’s optional OS85621 MOST ToGo reference design makes the creation of automotive ADAS and infotainment systems easy, enabling designers to focus on application software development.

The OS85621 and OS85623 H.264 video I/O companion ICs are available today and are offered in a BGA 196 package.
