CableLabs will host a 3DTV interoperability event in February, allowing manufacturers of 3D-capable cable set-top boxes, TV sets and test equipment to evaluate product implementations that are based on the OpenCable 3DTV requirements, or are designed to interoperate with such products. The interop, scheduled for Feb. 13-17, will draw from expanded testing capabilities in the CableLabs 3DTV research and demonstration lab.
