PARIS -- November 12, 2012

The newly launched UK TalkTalk TV service delivering live multicast and on
demand content via the recently released YouView connected TV set top box is
the first major TV service to exploit the latest high performance video
compression technology from ATEME. TalkTalk selected ATEME’s TITAN platform
for the YouView based service after being highly impressed by the picture
quality delivered by the underlying software encoder called EAVC4, according
to its Director of TV technology Brian Paxton.

“We needed to upgrade our current broadcast head end to allow us to expand our
channel line-up, and looked at all the main encoding vendors,” said Paxton.
“After evaluating these options we selected ATEME as the impressive picture
quality achieved by the new ATEME EAVC4 technology exceeded that of the other

TalkTalk has been using ATEME products since 2007, starting with offline
encoders for preparing movie and other on demand content. “Even then we were
impressed by the quality of the product,” said Paxton. But now ATEME has
opened up an even bigger gap over its rivals with the EAVC4 compression
engine, which enables operators to optimize video content for specific screen
sizes and available bandwidths. EAVC4 represents a major leap forward in
performance, with drastic speed improvements for all video quality (VQ)
settings, and the ability either to encode faster at the current VQ level, or
to significantly increase VQ while maintaining the current encoding speed.

The EAVC4 video encoding architecture exploits a combination of
multi-processor and multi-core 64-bit architecture, and multi-threading from
slice level up through macro block level, to achieve its efficiency gains.
This has involved a complete redesign by ATEME, resulting in up to 20%
bandwidth gains for progressive and interlaced content based on objective
measures, and even higher gains based on visual perception.

For TalkTalk these capabilities are essential as it campaigns to become one of
the UK’s major pay TV providers in the multiscreen era, leveraging its
extensive content catalogue to target its existing base of 4 million broadband
customers. The TV service is free to these existing broadband customers after
payment of a £50 ($80) installation fee for the YouView set top box, and will
provide access to over 100 broadcast channels, including free to air
programming from the BBC, ITV and many others, as well as extra paid premium
channels such as Sky Sports.


ATEME is a world leading provider of MPEG-4 / H.264 and MPEG-2 bandwidth
efficient compression technology. ATEME encoding solutions are deployed widely
for broadcast contribution links, distribution, multi-screen live streaming,
OTT and VOD applications. Find out more on ATEME’s technology and the EAVC4
