Is the Reference Implementation required for CableLabs Certification?
No. The Reference Implementation is one instance of OCAP that complies with the OCAP TCK; other instances that comply with the TCK may also exist and be Certified on a OpenCable Host Device. In all cases, an OpenCable Host Device must pass all of the applicable tests and otherwise comply with the applicable OpenCable specifications. See http://www.opencable.com/ and http://www.cablelabs.com/certqual/ for more information.
