capture video through TCP/IP protocol in labview

[sumanth]

Hi Friends, How to acquire video data using TCP/IP read? actually i am trying to control a robot using labview. This robot has WiFi card and has an ip 169.254.0.10. Robot control protocols are already burnt into blackfin processor, of the robot, example.... if i enter 8 in string control of front panel, robot will move forward, 2 is backward, 6 is right and 4 is left. Robot has camera and transmits images through tcp/ip protocols. well.... i am able to establish wifi connection between my PC nd robot and i am able to control it simply by entering corresponding numbers in string control of VI but i am not able to acquire video from the camera through TCP/IP read platelet. ( someone has created a java consol for this robot and i downloaded it from online forum. by running this consol i can control the robot and also accquire real time video) but i want to do the same using labview. please help.

You do realize that you are not actually reading any data, don't you? Your input to the TCP Read VI is the default which is a value of 0. So in essence you are saying read nothing. Also from reading through some of the information you pasted it appears that the video is streamed via a web browser. There simply reading from a TCP port will not accomplish what you want. Do you have the Interent Toolkit? That has an HTTP protocol implementation which may work for you though I don't think it will have what you want. It looks like you need to send an HTTP GET to retrieve the video image. You could also try using ActiveX or .Net to embed a browser window in your application.
