Celrun and Sigma Designs to Demonstrate Next Generation WiMedia UWB IPTV Set-Top Boxes at IPTV World Forum 2007

Celrun’s IP Set-Top Boxes Are Powered by Sigma Designs’ Media Processors and UWB Wireless Chipsets

LONDON — Celrun (Kospi:013240), a diversified IP set-top box manufacturer and Sigma Designs (Nasdaq:SIGM), a leader in digital media processing for consumer electronics, today announced that both companies will demonstrate the next generation of an IPTV set-top box at IPTV World Forum 2007 at the Olympia Conference Centre in London, England beginning March 5th through March 7th. The demonstrations will showcase advanced wireless and high definition (HD) video streaming features in Celrun’s IP set-top box powered by Sigma Designs. Demonstrations are available at Celrun’s Booth #146 and Sigma Designs’ Booth #97 on the main show floor.

Celrun’s IP set-top box is powered by Sigma Designs’ Windeo® chipset for UWB wireless video streaming and SMP8634 media processor. Sigma’s Windeo chipset enables Celrun’s set-top box with UWB wireless streaming of compressed HD content over an extended range. In addition, Sigma’s chipset provides an Intelligent Array Radio (IAR) technology allowing Celrun’s set-top box to overcome interference in a non-line-of-sight video streaming environment. The most demanded system-on-a chip (SoC) solution for HD IPTV set-top boxes, the Sigma Designs’ award winning SMP8634 media processor also equips the Celrun IP set-top box with advanced processing power integrated onto one chip.

“The ability to connect the hub to the IP set-top box wirelessly offers Celrun TV consumers greater flexibility and ease of operation,” said BJ Lee, vice president of marketing at Celrun. “We have been working on UWB technology for several years and we are excited to showcase our IP STB product with UWB wireless feature enabled by Sigma Designs’ UWB Windeo® Chipset.”

“Celrun has always been a pioneer in introducing new technology to the market,” said Hung Nguyen, vice president and general manager of the Wireless Products Division at Sigma Designs., “We are excited to be working with Celrun on this cutting edge IP set-top box with UWB wireless for HD video streaming. The combination of Celrun STB and Sigma Designs UWB will provide the best wireless solution for home entertainment and video distribution applications.”

Sigma Designs’ Windeo® chipset is an all-CMOS, Ultra Wideband transceiver based on the WiMedia MAC and PHY Specifications. The chipset is comprised of Windeo RF B7CW101 with three integrated radios and Windeo Baseband B7CW201 with PHY, MAC, embedded processor and multiple interfaces for A/V streaming applications.
