Seattle-based Widevine Technologies said today it has received an order for 300,000 Virtual SmartCard units from a Taiwanese telecom company.

Previously, the state-owned Chunghwa Telecom had ordered 500,000 units, which are used to deliver video-on-demand and other broadcasts to electronics devices. Chunghwa has an interactive television service that includes karaoke-on-demand.

Five or so years ago, Widevine made encryption software for video delivered over the Internet. But in 2002, the company cut employees and changed its focus to the more traditional markets of cable and telecom.

In April, Widevine raised $16 million in a third round of venture capital, bringing its total raised to $62 million.
