Ambarella Introduces S5 SoC for Professional High-Quality 4K and Multi-Imager IP Camera Designs

Ambarella, Inc., a leading developer of low-power, HD and Ultra HD video processing semiconductors, today introduced the S5 System-on-Chip (SoC) targeting professional high-quality 4K and multi-imager IP camera designs.

The S5 offers advanced features including 4K multi-exposure High Dynamic Range (HDR) fusion, 360° de-warp and ultra-low light processing. Maximum performance is 4Kp120 or 8Kp30 of H.264/AVC and 4Kp60 frames of H.265/HEVC, while supporting flexible multi-streaming, rate control and transcoding functions. The S5 supports the high-quality Main10 HEVC Profile (10-bit H.265) for outstanding representation of high contrast scenes and a wide color gamut. In addition, it leverages Ambarella’s SmartHEVC™ technology to radically reduce 4Kp30 video bitrates to between 512 Kbps and 4 Mbps, minimizing network bandwidth requirements and saving on storage costs. The S5 image sensor interface and its advanced 1-Gigapixel/s Image Sensor Pipeline (ISP) can be configured as up to four independent sensor inputs to allow development of high resolution multi-imager cameras.

“The S5 will play a critical role in the industry’s shift to 4K and H.265," said Fermi Wang, President and CEO of Ambarella. "With it, our partners gain a leading-edge image processor that delivers low power consumption, superior image quality, smart H.265 compression and a powerful quad-core CPU.”

The S5 includes a 1.2 GHz quad-core ARM® Cortex®-A53 64-bit CPU with floating point and NEONTM available for user applications. A Linux-based Software Development Kit (SDK) allows customers to develop highly differentiated products including 4Kp60 traffic cameras, 4x4K multi-imagers and surround view cameras, with support for advanced features including intelligent video analytics, in-camera edge storage and transcoding.

Ambarella will demonstrate the S5 at a private event during ISC West in Las Vegas, April 6-8, 2016.
