hdtv
directx
hdcp
opengl

Explanation:

HDCP (High - Definition Content Protection) is a copy - protection technology used for high - definition digital content. Since Blu - ray movies are high - definition and copy - protected, the video card and HDTV need to support HDCP to play Blu - ray movies. HDTV is just the type of television, DirectX is a set of APIs mainly for gaming and multimedia in Windows, and OpenGL is a cross - platform API for rendering 2D and 3D graphics, neither of which is essential for playing copy - protected Blu - ray movies on an HTPC connected to an HDTV.

Answer:

HDCP
