by displaying C on a split screen to B without interrupting
the A-B conversation. (1:43-63.) B is never placed on hold
because Ueno uses two separate interface circuits 202 & 203
to handle the two callers. Since Ueno shows C's image, he
does not address displaying C's name or number. Ueno does
not disclose the effect of having more than one TV phone in
operation at B's location when C's call arrives.
I The Krisbergh reference, among other things, displays
incoming and outgoing telephone numbers on a television
display. (2:66-3:10 and 5:35-54.) Krisbergh does not
display names. The reference does not address the display

does not disclose the effect of having more than one
telephone off the hook when a third-party calls.
