Recording From Digital Channel While Watching Another How Do I Use A Second Analog To Digital Converter Box To Record One Channel While Watching Another?

How do I use a second analog to digital converter box to record one channel while watching another? - recording from digital channel while watching another

I have digital 2 rabbit ears antenna and 2 boxes of converting analog to.
On the back of each converter box is:
"On Air"
"TV OUT"
"VIDEO" (yellow / white / red).

The back of a VCR:
"OUT" (yellow / white / red)
IN-1 (yellow / white / red)
"ANT IN"
OUT TO TV.

The back of the TV:
"VIDEO 1" (yellow / white / red - used for DVD)
"VIDEO 2" (yellow / white / red + green / blue / red)
"OUT" (yellow / white / red)
"Ant".

What can I do to, what to order:
1) you do not have to select the encoder to the recorded channel.
2) The ability to record channels Mulitple
View 3) value of Chanel and other

What is television, the video should be removed? A "3" or "online"?
Thank you!
