One of RealNetworks’ longest running online initiatives is its partnership with Big Brother, the CBS reality TV show. Now, Seattle-based Real is looking to bolster that offering (and other reality programs for that matter) through an investment in Campbell, California-based ClipSync.

For the past two years, ClipSync has powered RealNetworks’ SuperPass offering, which, among other things, provides unfiltered live feeds to Big Brother and other reality shows.

Through ClipSync’s technology, fans of the show can participate in community conversations, audience voting, trivia, games and more.

Details of the investment are not being disclosed.  Other backers of ClipSync include KPG Ventures and Draper Fisher Jurvetson.

Michael McMurray, General Manager of Content Services at RealNetworks, said in a statement that SuperPass helps fans interact with shows in much deeper ways.

“For entertainment and production companies, we are providing new ways to further engage their large and loyal fan bases while extending and monetizing their brands,” McMurray said.
