RealNetworks said that it would cut approximately 90 jobs out of its total workforce of 800, adding that it would take $4m (£2.6m) to $6m (£3.9m) restructuring charge.
As part of the restructuring, Real said it was refocusing the company's systems business around its recently introduced Helix Community Platform media delivery software and Helix Universal Server.
Helix is based on the company's existing client and server software, allowing content to be delivered from a server to desktop PCs and other devices over the Internet or a network. But Helix's real edge is that it can deliver streaming audio and video in a variety of formats, including Windows Media and MPEG-4.
The company said that it planned to focus its consumer business around the RealOne media subscription service, and will be organising its international operations around Helix and RealOne.
Real's rival, Microsoft, is planning to release the beta of its Windows Media 9 media delivery software next month, which is expected to increase competition between the two companies.
