Vertical Interval Reference...I have two G-E sets with this feature and both have great pictures.
From what I understand, the VIR takes broadcasted info which is hidden in the vertical blanking field and sets up the receiver's chroma and luminance levels to the program material... It's a clever invention since there will always be a hidden blanking interval in an NTSC signal.
Not sure if later sets had this built in,, I bet they did since the microprocessor and jungle ICs became ubiquitous in 80s-90s sets.
