Switching Video modes

David_w

What kind of command would I use to switch Video modes, video to s-video back to video using the same button. I have try the below code but it stays in S-video mode. It will go from Video to S-video but remain there inless I go to RGB and start over.

IF (!Video_Input)
{
send_string dvPlasma,"'@G',13"
wait 20 send_string dvPlasma,"'%A1012',13"
SEND_STRING 0, "'%A1012',13"
Off [RGB_Input]
On [Video_Input]
}
Else IF(Video_Input)
{
send_string dvPlasma,"'@G',13"
wait 20 send_string dvPlasma,"'%A1014',13"
SEND_STRING 0, "'%A1014',13"
On[Video_Input]
Off [RGB_Input]
}
Else IF(Video_Input)
{
send_string dvPlasma,"'@G',13"
wait 20 send_string dvPlasma,"'%A1012',13"
SEND_STRING 0, "'%A1012',13"
On[Video_Input]
Off [RGB_Input]
}

}

The third block of the code segment will never, ever execute. Essentially, you have

IF ( NOT A ) { }
ELSE IF ( A ) { }
ELSE IF ( A ) { }

I'm not 100% sure what you're trying to do or what all those variables are for, but you should rethink your logic.

Basiclly I am trying to go:

Button press 1:
Goes to Video mode

Button Press 2
Goes to S-Video mode

Button Press 3
Goes back to Video mode.

and the cycle repeats every time I hit the button.

You are using "Video_Input" as a test. You are turning it on, but not off. So the code block for Video will run only the first time, but not after. You need to change "Video_Input" to off when you are going to S-Video. Also as mpullin says, you don't need the last block of code.

Hey thank you that worked out fine.

mpullin

Oh, so that's what's going on. In that case, you don't need the RGB_Input variable at all. No need to use two stones to kill one bird

Say I had to do the same thing with RGB but there were 3 RGB sources. Would I then need to write a switch case on/off for that. RGB 1, RGB 2, and RGB 3 and cycle back through.

It would be more efficient by far to have one variable to hold the current source, and put 1 in the variable when it the input was RGB1, 2 when the input was RGB2, etc. You would then be able to use switch/case:

switch(nRGB_VAL){
     case 1:
          // set input to RGB2
          nRGB_VAL = 2
     break
     case 2:
          // set input to RGB3
          nRGB_VAL = 3
     break
     case 3:
          // set input to RGB1
          nRGB_VAL = 1
     break
     default:
          nRGB_VAL = 1 // so it doesn't get stuck
     break
}

Nrgb_val

Hey, I am really confused on where the nRGB_Val 1,2,3 are set at. I dont understand how do define it. I believe it to be a Variable because it would change cause of RS-232 codes that need to be sent. Is that correct? Are the cases going to look like this:

switch(nRGB_VAL)
{
case 1:
// set input to RGB2
{
nRGB_VAL = 2
send_string dvPlasma,"'@G',13"
wait 20 send_string dvPlasma,"'%A1000',13"
SEND_STRING 0, "'%A1000',13"
On [RGB_Input]
break
}
case 2:
// set input to RGB3
{
nRGB_VAL = 3
send_string dvPlasma,"'@G',13"
wait 20 send_string dvPlasma,"'%A1001',13"
SEND_STRING 0, "'%A1001',13"
On [RGB_Input]
break
}
case 3:
// set input to RGB1
{
nRGB_VAL = 1
send_string dvPlasma,"'@G',13"
wait 20 send_string dvPlasma,"'%A1002',13"
SEND_STRING 0, "'%A1002',13"
On [RGB_Input]
break
}
default:
{
nRGB_VAL = 1 // so it doesn't get stuck
send_string dvPlasma,"'@G',13"
wait 20 send_string dvPlasma,"'%A1000',13"
SEND_STRING 0, "'%A1000',13"
off [RGB_Input]
break
}
}

Thanks

Hey it works, Thank you so much... I figured something out with help of course. Thanks again.
