	Digital television receivers (as opposed to digital broadcasts)
have been in the works for a number of years.  The Toshiba is just the
first to be offered in the US.  The "window" is availble in 1/4 or 1/16
of the screen and you can pick the quadrant in which is dispalyed.  It
has its own tuner and will except standard NTSC composite video for the
"window".  It does not need a genlocked signal because it has a frame
buffer that acts as a FIFO for the second  signal.  A neat toy, it
retails for around $1200.
