Suggested User Instructions
For a product incorporating the TMC2360, part of the docu-
mentation is expected to include operating instructions
describing the functions of the TMC2360 user controls. A
recommended text fragment follows.
Three external controls may be used to:
1)
position the image within the boundaries of the TV
screen.
2)
control vertical resolution.
Each control is a button that can be momentarily depressed
to execute one cycle of the selected function.
Position Controls
Position controls shift the viewed image horizontally or ver-
tically to reveal portions of the image that are located near
the edges or in the overscan areas. At power-up, the default
position is the midpoint of the adjustment range.
Each time the VERTICAL POSITION button is depressed,
the TV window moves down by eight lines. At the lowest
position (-64 lines) the direction reverses and depressing the
button moves the image up in 8-line increments to the high-
est position (+64 lines). At this point the direction again
reverses and the next sixteen pulses move the image down to
the lowest position.
When the HORIZONTAL POSITION button is depressed,
the TV window moves eight pixels to the right. At the maxi-
mum right position (+64 pixels) the direction reverses and
the next sixteen pulses move the window left to the maxi-
mum left position (-64 pixels). Direction again reverses and
the next sixteen pulses move the image right.
Flicker Filter
Annoying artifacts can be eliminated by selecting one of
three lter modes which trade-off vertical resolution against
icker. For example, without the lter, a single VGA line is
encoded into only one eld of the TV display. If there is high
contrast between this line and adjacent lines, it will icker at
30 Hz in NTSC or 25 Hz in PAL.
Depressing the FILTER button indexes through the lter
functions shown in the table below:
The lter should be selected for best appearance on the TV
screen. Optimal selection will depend on the image being
encoded.
