Samsung, Time Warner Cable and Advance/Newhouse Communications announce that interactive digital cable services are now live on the Samsung HL-S5686C Open Cable Application Platform (OCAP) compliant DLP HDTV and SMT-H3050 High Definition Set-top Boxes.

The new interactive cable service is currently available in NYC and is supposed to be soon coming to Milwaukee (=beer city).

Time Warner Cable's new interactive cable service includes its OCAP Digital Navigator and its in-house developed Interactive Program Guide. In 2007, Time Warner Cable and Advance/Newhouse Communications will continue to rollout OCAP on Samsung OpenCable products in other divisions of Time Warner Cable and Bright House Networks.
I guess you should not confuse the Samsung HL-5686C with the Samsung HL-S5686W DLP HDTV currently on sale on Amazon.com.

More details about the OCAP Samsung stuff can be found in this Samsung press-release.
