MultiVision was one of the earliest implementations of PIP (picture-in-picture) television available for purchase by users, pioneered by engineer George Schnurle III and sold by the San Jose, California-based company Multivision Products Inc.[1] The original MultiVision model was a box that measured 17 inches (43 cm) by 10.5 inches (27 cm) and was 3 inches (7.6 cm) high.
For monaural broadcasts and VHS tapes, the device could provide synthesized stereo audio.
The tunerless MultiVision 1.1 model looked virtually identical to the 3.1 except in rear view, and featured 4 composite, plus left and right audio input sets, plus switchable external audio and video processor loops.
On the 1.1 and 3.1 models, the audio could be set in sync to either the main source or the PIP or selected independently.
Their remotes featured angled output ends, which facilitated accurate button selection whilst reclined.
