Conexant has combined simultaneous cable-modem functionality and interactive cable broadcast capability for set-top box applications in a single-chip digital cable transceiver, the CX24420. According to the company, it is the first to achieve this combination.
"Our latest set-top box device is truly a design breakthrough that combines cable TV with Internet connectivity and is configured to integrate with Conexant's home-networking technologies including voice over IP solutions," said Anthony Simon, director of marketing for cable set-top platforms in Conexant's Digital Infotainment Division, in a statement. "The chip will enable a new generation of advanced home gateways and interactive set-top appliances."
The CX24420 provides the features that support personal video recording (PVR), letting consumers record, pause, rewind and fast-forward a television program in real-time. And manufacturers get more flexibility to support multiple global standards and upgrade their products via the CX24420's software media access controller.
Conexant cites technology research firm Cahners In-Stat Group as reporting cable-modem functionality is expected to become a standard feature in high-end set-top boxes over the next two years, and digital cable set-top box shipments are poised to grow from 10.3 million in 2000 to 15.7 million in 2003.
