Sending Video over the wireless network

[akang]

I am considering capturing images from a IEEE 1394 camera and sending it over the Wireless network to another computer.  The reason we want to do that is to make the
camera device light and portable by connecting it to a portable tablet computer.

What kind of protocol is the best way to transfer the image. The TCP or UDP in labview convert data into string before the transmission which are very inefficient. I just want to streaming the raw image data, maybe with some protocol overhead.  Did National Instrument has any package to do that or any other software packages available?

There might be another solution is to use the Ethernet cameras instead of 1394 cameras.

Would it be possible for the Labview application on a remote desktop computer to acquire the Ethernet camera over a WiFi wireless connnetction in between ?

Thanks

Hello Cindy,

If you want to transfer data across a network, TCP would be the most efficient method (wireless is typically not as successful as Ethernet due to the overhead).  There is actually a very useful knowledgebase document that discusses the various methods used to transfer image data across a network.  If you go to our main site http://www.ni.com and search using the keywords “Images Over Network”, the first link is entitled Streaming IMAQ Images Over a Network (or Internet) which gives brief descriptions if you choose to use TCP/IP, Datasocket, LabVIEW web server, or ActiveX.  Another very informative document results in that same search and is titled Transfer Images Over the Network which actually gives examples illustrating different ways to send images.  I hope this helps.  Please let us know if you would like further clarification or assistance regarding this issue.Vu D
