The digital broadcast technology group, Kudelski, has signed deals in both Hong Kong and Australia.
Kudelski said in a statement on Friday that Hong Kong Cable Television had selected Kudelski's Nagravision as a partner for its migration to digital television broadcasting.
Nagravision will act as the integrator for the full system and provide its conditional access solution.
Hong Kong Cable, a unit of i-Cable Communications, will go digital from August and the first phase of the conversion, for more than 200,000 subscribers, will be completed by April 2002.
Australia's Cable and Wireless Optus gave a contract to Nagravision to provide conditional access systems for trials of interactive digital television. The trial concerns 300 homes in Sydney.
Kudelski has been in an expansive mood of late buying Ticketcorner from UBS and acquiring Lausanne-based digital multimedia group Lysis in May.
