3D video multiplexer

The ‘3DMUX’ allows the creation of field-sequential 3D video from a pair of genlocked video cameras. Field-sequential 3D Video is the defacto standard for the recording of stereoscopic 3D information using the PAL and NTSC video standards.

The 3D Video signal created using this device can be used for any of the following purposes:
(a) record onto video tape or DVD,
(b) 3D viewing using an appropriate 3D display or HMD (head mounted display),
(c) Stereoscopic 3D projection using the ‘S-Video Demultiplexer’.
