Microchip Technology has announced the availability of the OS85621 and OS85623, which are the world’s first H.264 video I/O companion integrated circuits (ICs) optimized for the Media Oriented Systems Transport (MOST) high-speed automotive infotainment and Advanced Driver Assistance Systems (ADAS) network technology. 
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 quickly implement content-protected video transmission solutions. You can now transmit video streams with restricted access from devices (e.g., DIDs, digital media drives, and TV tuners) as encrypted H.264 over a MOST network.
The OS85621’s on-chip DTCP coprocessor accelerates the computation-intensive operations required for DTCP authentication and content protection. You can simultaneously route up to eight independent data streams through the DTCP coprocessor’s cipher 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—which has no DTCP coprocessor—an excellent option for camera-based ADAS applications that are designed to enhance vehicle safety.
The OS85621 and OS85623 H.264 video I/O companion ICs are now available in a BGA 196 package. Volume pricing starts at $8.
