3D to 2D Demultiplexer Box system is designed to convert a 3D HDMI v1.4 video signal in ‘Side-by-Side’ (Left-eye/Right-eye) or ’Frame Packing’ (Top/Bottom) format, to an HDMI 2D v1.3 video signal compatible for use in applications using two HDMI 2D projectors or one HDMI 2D HDTV. A quality product perfect for converting a 3D video signal input from your 3D DVD or BluRay player to an HDMI 1080p@60Hz 2D video signal output. Ideal for quality movie viewing using your existing 2D HD equipment.

To use with twin 2D projector applications, 2 x 3D to 2D Demultiplexer Box’s are needed, one each for ‘Left-eye/Right-eye or ‘Top/Bottom’ 3D formats. An HDMI 1in:2out Splitter is also required to interface the 3D HDMI source to each 3D to 2D Demultiplexer Box. To use with a 2D HDTV application, simply connect 1 x 3D to 2D Demultiplexer Box between your 3D source and 2D HDTV using two HDMI cables.

The 3D to 2D Demultiplexer Box automatically detects the received 3D format of the source equipment (‘Left-eye/Right-eye or ‘Top/Bottom’). Simple front-panel button operation selects the 3D Demultiplex conversion to be performed to output a compatible HDMI 2D 1080p@60Hz video signal for connection to your 2D projectors or HDTV. Full support for video input resolutions in 2D: 480i/p ~ 1080i/p@50/60Hz and 3D: 720p@50/60Hz (Side-by-Side / Frame Packing) and 1080p@24Hz (Frame Packing).
