GEM – (Globally Executable MHP) - (See DVB.org for updates to this definition.) - The International Telecommunications Union (ITU) and the DVB developed a new international Application Programming Interface (API) for middleware between (1) the OpenCable Application Platform (OCAP), which is an interactive television middleware software layer for US cable; and (2) the Multimedia Home Platform (MHP), the open, multi-platform middleware specification developed by the DVB.

The ITU calls this new API "Recommendation ITU-T J.202," while the DVB calls it "Globally Executable MHP," or "GEM" for short. GEM could act as the execution engine for the OpenCable Application Platform and MHP.
