MOSCOW -- May 29, 2008 -- VimpelCom-Communications ("VimpelCom") and Microsoft Corp. today announced a strategic partnership to deliver new connected TV experiences to consumers in Russia and the Commonwealth of Independent States ("CIS") through Corbina TV, which will be powered by the award-winning Microsoft Mediaroom Internet Protocol TV (IPTV) and multimedia software platform. Corbina TV will be operated by Corbina Telecom, a subsidiary of VimpelCom.

The agreement was officially concluded by Jean-Pierre Vandromme, Executive Vice-President of Network Resources Management of VimpelCom and CEO of Golden Telecom, and Steve Ballmer, chief executive officer of Microsoft, in a meeting on Friday May 23 in Moscow.

The video and whitepaper are designed to clarify the issues and offer solutions," Kim explained.

StrikeTracker Version 1.5 provides real-time analytics, self-service
live event provisioning, policy-based content access protection, and
more

STREAMING MEDIA EAST, NEW YORK CITY - May 20, 2008 - Highwinds Network
Group, Inc., a multi-platform IP services and content distribution
provider, today announced significant enhancements to its StrikeTrackerT
dashboard for the company's content delivery network (CDN). The new
StrikeTracker Version 1.5 content management and reporting console
provides a wide range of advanced capabilities -- including real-time
analytics, self-service live event provisioning, policy-based content
access protection, and other important features not available with most
other CDN offerings. Attendees at Streaming Media East are invited to
explore the innovative new features of StrikeTracker 1.5 at Highwinds'
exhibit -- Booth 226.

"With StrikeTracker 1.5, we have implemented an unmatched feature set
for content management, reporting, and account management that further
differentiates Highwinds as the preferred CDN for the service provider
channel," said Highwinds CTO Josh Gagliardi. Gagliardi added that
StrikeTracker 1.5, which takes full advantage of the latest Adobe Flex
technology, "also provides graphical richness and ease of use that is
second to none when compared to other CDN dashboard offerings."

Real-Time Analytics for Fast, Actionable Data
The enhanced analytics package in StrikeTracker 1.5 provides
byte-accurate reporting delivered from the edge within 30 seconds of
delivery. Multiple dashboard views group related pieces of information
at various levels of detail. When supported with real-time analytics,
these views allow companies to make decisions that affect their online
content monetization strategies on a minute-by-minute basis, throughout
a campaign, without having to wait hours or days for actionable data.

Self-service Live Event Provisioning
Live streaming events can now be provisioned through StrikeTracker
without the necessity of contacting Highwinds. Using StrikeTracker's
point-and-click interface, event publishing points can be configured on
the fly and are ready to begin streaming immediately.

Policy-Based Content Access Simplifies Security Management, Maximizes
Control
The ability to control content access based on protection policies is
now available. Through the StrikeTracker interface, users can set
content protection policies on a per-folder basis. These policies are
inherited down through the content hierarchy, allowing for ease of
security management and maximum control. Support for multiple
protection schemes is available, including signed URLs, referrer
restrictions, HTTP basic authentication, and geo-blocking.

Raw Logs Provide More Detailed Information for Analysis
StrikeTracker 1.5 provides the ability to download "raw" logs -- the
line-by-line activity of a server -- filtered on a per-customer basis.
These logs are formatted according to industry standards, and can be
processed by a variety of commercial specialty log analysis tools.
Built on top of the same technology that supports the real-time
reporting features in StrikeTracker, the delivery of raw log data is
delayed by no longer than 15 minutes.

Virtual Host Configuration
Virtual Host Configuration is important to channel partners interested
in "private labeling" the Highwinds CDN. It enables them to apply their
own name, logo and other branding elements to the StrikeTracker
dashboard, creating the appearance that the CDN is their own, not
Highwinds'.

Imagine's Ron Gutman to Present on Video Layer QoS, Monday, May 19

SAN DIEGO, Calif. - May 7, 2008 - Imagine Communications, the leading innovator in advanced digital video processing and multiplexing solutions, today announced plans to demonstrate its powerful ICE™ Video Platform across all cable digital video applications at The Cable Show '08, May 18-20 in New Orleans. In addition, Imagine's co-founder and CTO Ron Gutman will present his paper entitled "Video Layer Quality of Service (QoS): Unprecedented Control and the Best Video Quality at Any Given Bit Rate," during the session called "Bit Parts: New Approaches for Managing Video Encoding" on Monday, May 19, 10:45a.m.-12:00p.m. in room #211.

"We're excited to demonstrate how cable operators can deliver the highest video quality while still adding bandwidth-intensive content, such as HDTV and VOD, to their systems," stated Marc Tayer, Imagine's SVP of marketing and business development.

In booth #529 at The Cable Show, attendees will see how Imagine's ICE Video Platform, which leverages breakthrough video processing and multiplexing technology, can help cable operators deliver the highest video quality while cost-effectively increasing bandwidth efficiency across all digital platforms. Imagine's core technologies of Interchangeable Compressed Elements (ICE™) and video quality measurement (ICE-Q®) address the video quality needs of cable operators. ICE-Q is the industry's first accurate objective video quality measurement subsystem. It consists of algorithms built into Imagine's video processing solutions. By accurately emulating the human visual perceptual system, ICE-Q ensures the highest video quality at any given bit rate.

The following solutions will be demonstrated:
" The ICE Broadcast System, Imagine's initial product, offers the highest video quality and most efficient multiplexing of HDTV and SDTV broadcast channels, allowing cable operators to add dozens more linear HDTV signals at excellent video quality.
" The ICE VOD System allows operators to deliver up to 50 percent more VOD streams per 256 QAM channel, with enhanced video quality-providing the ideal platform for next-generation, consumer-controlled PersonalizedTV services.
" The ICE SDV System further enhances the inherent bandwidth efficiency of switched digital video, while dramatically improving the video quality of existing SDV networks.
" Video Layer Quality of Service (Video Layer QoS) offers an unprecedented level of control by allowing content providers and cable operators to pre-calibrate and establish video quality levels, at the video layer, which can be sustained from content origination all the way to the set-top box.

LONDON, UK, 08 MAY 2008 - The pay-TV market in Western Europe is
generally considered to be mature, but the increasing deployment of IPTV
services will see the market enjoy a modest rate of growth in the number
of households subscribing to pay-TV services, according to the latest
research published by Analysys Mason, the premier advisors on telecoms,
IT and media (www.analysysmason.com).

According to the Analysys Mason report, Pay TV in Western Europe: market
sizings and forecasts 2005-2013, the number of households subscribing to
pay-TV services will increase at a CAGR of 3.2% from 90.6 million in
2007 to 109.2 million by the end of 2013.

"The adoption of IPTV services will be driven by a combination of
factors, including the proliferation of multi-play strategies; latent
broadband growth; improving brand recognition, broadening content
offerings, and the general move towards digital TV services as the
analogue TV signal is switched off in Western Europe," explains the
report's author Richard Hadley. "However, the growing popularity of
IPTV among households will contribute to a slow down in pay-TV spend as
these predominantly lower-value TV packages are increasingly bundled
with telecoms services."

Key findings from the new report include:
- spend on pay-TV subscriptions, including expenditure on PPV/VoD
services, will grow at a CAGR of 4.5% from EUR21.5 billion in 2007 to
EUR28.0 billion by 2013
- CATV will continue to be the most popular pay-TV platform,
accounting for 48% of Western European pay-TV households at 2013.
However, this figure represents a notable decline in market share, down
from 58% at the end of 2007
- DTH will make up 29% of Western European pay-TV subscriptions in
2013, but will account for 54% of pay-TV spend, compared with 28% and
52%, respectively, in 2007
- IPTV will increase its share of the Western European pay-TV
households from 6% to 15% between 2007 and 2013. However, it will
account for only 8% of pay-TV spend in Western Europe in 2013.

The report provides a detailed breakdown of pay-TV households and spend
by service platform and subscription type in Western Europe as a whole,
and for France, Germany, Ireland, Italy, the Nordic region, Spain and
the UK, individually.

The report is available to purchase online at http://store.analysys.com,
priced at GBP1700 (approximately [EUR2170] ) plus VAT.
