Separating Composite video signal???

I have a small monitor that has separate video signals, video, horz/vert
sync signals. I am looking to interface a composite video camera to this
monitors input.

I have read about a IC chip that will separate the sync signals, the
LM1881. How would I get the video portion separated from the composite
signal to feed it the video input circuitry of the monitor?

Thanks.

SomeBody:
Depending on the sophistication of the monitor's input circuitry you can
sometimes get away with splitting the composite video feed from the camera
and feeding it into both the video and sync inputs of the monitor..... many
times the monitor will "find" the sync signals just fine from a composite
video signal.

The LM1881 does not have a horizontal sync output. Intersil's EL1883
is probably a better choice, although it may be harder to find:

FWIW, Intersil appear to be offering free samples.
