Hi all,

I want to transmit an image/video from one node to another node using  
GNUradio, but I don’t know how to divide an image or video into multiple  
packets. I want to make it real time in the sense that an image/video is  
loaded, divided in to multiple packets and then transmitted  
continuously.  
Can any one tell me how to do this in GNUradio?  
Thank you very much  
Van-Ly

Hi,

If I understand correctly you want to stream a video from one node to  
the  
other. You could use VLC for that and UDP source and sink in GNU Radio.

Basically use a UDP Source on the sender side and use VLC to stream a  
video  
to the UDP source’s port.  
On the receiver side, use a UDP Sink and use another instance of VLC to  
receive a stream for the UDP sink’s port.

This is a really open question. How do you want to transmit? If you use  
OFDM, you can simply prepend a stream to tagged stream block.
