Ambarella A6 chip platform deployed by Harmonic
Santa Clara, California

Ambarella A6 supports multiple-screen delivery and adaptive streaming in Adobe, Apple, Microsoft formats with HD/SD MPEG-2/H.264 transcoding and transrating.

Ambarella, Inc., a leader in low-power, high-definition video compression and image processing semiconductors, has announced that Harmonic Inc. is utilizing Ambarella’s A6 semiconductor platform. First introduced last year, the A6’s small footprint, low power and flexible multi-streaming architecture enable a new class of high-density, high-quality systems that use a fraction of the power and space compared to traditional solutions.

“Harmonic is a leading provider of video delivery solutions to any device, and our strong relationship with Ambarella facilitates development of best-in-class video processing technologies,” said Jean-Christophe Morizur, Senior Director of Broadcast Headend Products at Harmonic Inc.

“Operators are searching for solutions to keep up with an increasing number of formats and new stream delivery into mobile and IP but without compromising video quality,“ said Fermi Wang, CEO of Ambarella, Inc. “The A6 platform is a scalable and flexible platform to meet these evolving requirements.“A

Ambarella A6 Features
The A6 supports 1080p60 encode and full HD MPEG-2 and H.264 BL/MP/HP transcoding using full decode and re-encode with rate-distortion-optimization (RDO) and 3D motion compensated temporal filter (MCTF) noise reduction to ensure highest compression efficiency. A6 requires 32-bit DDR for the full feature set allowing for up to 24 HD channels of H.264 encode in 1RU. The software architecture supports multiple input and output streams with on-the-fly configuration of resolution, frame rate, and quality for 3-screen/many-screen delivery and adaptive/smooth streaming with support for the Adobe, Apple and Microsoft formats.

The A6 SDK offers a rich feature set and flexible ARM API’s allow for developer differentiation and tuning. The multi-streaming software architecture supports virtually any combination of inputs and outputs while preserving PTS throughput the system and managing discontinuities and meta data. In addition to encode and transcode functionality, the A6 SDK adds rateshaping, splicing, overlays, and ad insertion. A wide range of coding modes allow on-the-fly changes of GOP, resolution, profile, and quality. Other features include 3D, scene detection, telecine handling, F-code assessment and advanced rate control.Pricing and Availabilit
