how can i capture image from tv card [AVerTVStudio203(M168)]

[hldn]

Dear all,

i am new at LabView programming, i found some topics on the forum but i can't find the exact solution.

My test system consists of

1] software [ Labview 8.5 ]

2] tv card [AVerTVStudio203(M168)]

3] avertv [viewing and recording software of the tv card]

4] dvb- s receiver (set top box to receive satellite signals)

tv card has 3 inputs

 1] 75 Ω TV Antenna Input ,2]Composite (RCA) video input, 3] S-Video

receiver is connected to tv through composite rca connection.

My question is ?

Can i take a snapshot, capture a photo with this configuration using Labview ?

Best Regards

Hi hldn,

yes i´m sure you can, because you can always do a screenshot and then you got it. It could also be possible that your tv program has ActiveX support.

how can i do a screenshot from labview,

i should do everything from labview,

i should take this snapshot photo, and compare it with reference "jpeg" files, to see if the stb works or not

sorry of course i want to obey the forum rules

thanks but i got the attached error message,

0] how will i check that all the pathes to the dll correct,

0] will i edit these pathes, or move the files to that folders,

where can i find a brief explanation for this, and since i am very new in labview some more questions

1] i have found one more application for viewing analog sound by labview using the on board sound card waveio042.zip

my question is it possible to view the video signal like this by the help of tv card or graphics adaptor of the pc ?

2] if not i will try to use screenshot and image processing, the question is

how can i make this two codes , one for audio and  video , run one after another,

and also will i need extra sw for image processing by labview

best regards

Hi hldn,

if you download the LV8.0 version it could be that there are some error lines are broken. The path to the dll has to be the right one to the kernel32.dll and the user32.dll. You will find both in your windows system directory. connect the error lines and it should work.
