= CR/LF

• = space

= Video inputs, 1 - 4, 0 = none (black)

= Audio inputs, 1 - 4, 0 = none (mute)

= Audio gain, 0 thru 9 (dB)

= Audio attenuation, 1 thru 15 (dB)

= Numerical value, -15 thru +9

= User presets, #1 thru 128

= Audio switch mode (how audio is switched between inputs),

0: beginning of duration; 1: middle of duration; 2: end of duration;
3: fade (gradual)

= Picture contrast, 0 - 150

= Picture brightness, 0 - 50

= Picture tint, 0 - 32

= Picture color, 0 - 100

= 1 (on) or 0 (off)

Xe

= Effect type, (0 - 10) 0: cut; 1: dissolve; 2: soft wipe; 3: solid wipe;

4: soft curtains; 5: hard curtains; 6: square; 7: diamond; 8: circle;
9: X effect; 10: + effect

i

= Video output type, 1: NTSC; 2: PAL

j

Xk

= Duration period, (0 - 48), where 0 = 0.2 seconds and each increment of

the duration period adds 0.1 seconds to the duration time.
As examples, a duration period of 25 is equal to 0.2 + (25 x 0.1) = 2.7
seconds, and a duration period of 48 is equal to 0.2 + (48 x 0.1) = 5.0
seconds.

3: bottom-to-top; 4: top right-to-bottom left; 5: top left-to-bottom right;
6: bottom right-to-top left; 7: bottom left-to-top right

Transition list B, (0 - 7) 0: horizontal in; 1: horizontal out; 2: vertical in;
