OpenCable Applications Platform
CableLabs tru2way, OpenCable (OCAP)

The OpenCable Applications Platform (OCAP) specification, also known as tru2way, is a middleware software layer specification. The OCAP specification is intended to enable the developers of interactive television services and applications to design such products so that they will run successfully on any cable television system that deploys tru2way/OCAP services, independent of set-top or television receiver hardware or operating system software choices.

The OCAP specification enables manufacturers and retailers of set-top boxes, television receivers and other devices to build and sell attractive and capable devices to consumers that will support all digital services including future interactive services delivered by cable operators to devices currently available to consumers via lease from cable operators.

The issued OCAP 1.0 specification was released in December 2001 and is available from CableLabs at OpenCable Specifications. OCAPTM, OpenCableTM, tru2way TM are trademarks of Cable Television Laboratories, Inc.
