Comcast announced Tru2way technology at the 2008 CES, they describe it as: "Tru2way™ technology is the new name for the “OpenCable Applications Platform” (OCAP) that’s being built into televisions, set-top boxes and other electronic devices". They also state on the site: "With tru2way technology, cable companies, content developers, network programmers and consumer electronics companies can quickly and easily deliver the interactive services consumers want. Because of tru2way technology’s open standards, developers only have to write one version of an application, and it will work on almost every cable system in the United States as well as in other countries."
I have a wait and see attitude on this technology. Personally I hope it pans out, but I feel a little let down by the CableCard technology with its on again, off again acceptance.
