C&S Technology Inc.is an image total solution company, and has made a continuous growth since its establishment in 1993 by taking the industrial lead at home and abroad based on its technological power of image & voice processing and solutions.

It holds a differentiated core chipset based on the highly advanced semiconductor design technology. And it has developed such chipset-loaded video phone, “Vizufon”, drawing much attention at home and abroad as a core terminal of BcN. It has laid the market foundation by making inroad into China, Japan, Europe, along with growing domestic market and serving as a test bed for world video phones.

Furthermore, it developed a multimedia chip dedicated for DMB (digital multimedia broadcasting) that enables users to receive TV broadcasting service anywhere during high-speed move. Its chips were commercialized in earnest from February 2005, taking the lead in DMB market.

C&S Technology is determined to make active inroads into multimedia communication market beginning with BcN, DMB and ASIC business. It will make best efforts to take a firm root as a representative venture company in Korea and grow into a company along with shareholders and customers.

CRONUS

Cronus is a chipset exclusively for VoIP device that processes voice and data on the Internet or in the mobile environment. A variety of audio decoders are embedded such as narrowband voice codec including G723.1/G.711/G.729, G.722 which is ITU-T compliant standard broadband codec and MP3/AAC. Cronus is applicable to VoIP phone, WiFi phone, Digital mobile communication-based CoIP phone, Residential gateway (One to four port), TPS (Triple Play Service) set-top box that supports Internet, Broadcasting and Communication services, home networking device, MP3 player, dual mode mobile phone that simultaneously supports CDMA/GSM phone and VoIP, and other communication devices. Cronus can be used as main processor for the IP -based communication devices and as co-processors for various devices that need communication functions.
