AmbaCast 8000 Enables Harmonic’s New Ellipse® 3000 Video Contribution System

Business Wire

SANTA CLARA, Calif. -- April 08, 2013

Ambarella, Inc. (NASDAQ: AMBA), a leading developer of low-power, HD video
compression and image processing semiconductors, today expanded upon its
position as a leader in the video infrastructure market with the introduction
of the AmbaCast 8000 System on Chip (SoC).

The AmbaCast 8000 SoC provides a flexible platform to increase the quality and
the density of video transcoders and video contribution links. For transcoding
applications, the SoC can decode and re-encode multiple HD or SD streams into
a variety of resolutions and bit-rates as required for playback on
smart-phones, tablets, and notebooks. The SoC’s twin Dual Core ARM® Cortex™-A9
CPUs provide the required performance for encoding and transcoding multiple
channels of audio, including support for Dolby® Digital Plus. The SoC delivers
the high quality, low bit-rate, and low delay encoding required for video
contribution systems that transmit video from remote sources, such as
satellite news gathering units, to broadcast studios, or from broadcast
studios to uplink centers or cable head-ends.Harmonic's Ellipse® 3000,
announced at NAB 2013 in Las Vegas, is the industry's first video contribution
system to leverage the AmbaCast 8000.

“The AmbaCast 8000 codec flexibility and 10-bit support make it well-suited
for high quality contribution encoding applications,” said Tom Lattie, Vice
President of Products, Harmonic. “We are very pleased to be working with
Ambarella for the Ellipse 3000 contribution encoder.”

“Ambarella's integration of Dolby audio processing technologies on the
AmbaCast 8000 will make it easier for encoding and transcoding professional
solutions vendors to support Dolby Digital Plus in their products and will
help make high quality surround sound delivery widely available across all
media workflows -- broadcast, online, PCs, games, and mobile,” said
Jean-Christophe Morizur, Senior Director, Professional Solutions at Dolby
Laboratories.

The AmbaCast 8000 SoC supports both the H.264 and MPEG-2 video standards and
is capable of transcoding between the two. It enables exceptionally high
quality video encoding, including both 4:2:2 and 10-bit video compression and
with very low delay. The SoC is capable of simultaneously decoding and
re-encoding four full HD channels, eight 720p HD channels or twenty standard
resolution SD channels. It can encode video up to 4K or Ultra HD resolution.
Fabricated in 32nm CMOS process, the AmbaCast 8000 enables systems with
extremely low power consumption.

“With the introduction of the AmbaCast 8000, Ambarella is pleased to enter the
video contribution market while extending our product portfolio for video
transcoding applications,” said Fermi Wang, President and CEO of Ambarella.
“We are delighted to partner with Harmonic to deliver its new Ellipse 3000
contribution system and with Dolby to enable Dolby Digital Plus.”

Pricing and Availability

The AmbaCast 8000 SoC is currently sampling to qualified customers. Pricing
information can be obtained directly from Ambarella.
