Hi…  
I want to transmit video by using 16qam/4qam using constellation  
receiver. Can you kindly send me the flowgraph to do that if it can be  
done?

thank you in advance.

with regards,  
vishwanath

Hi Vishwanatha,

no, there’s no pre-existing flow graph to do that; however, from a SDR  
perspective, video is “just” data, so pick your favourite transceiver  
GRC file, and get data in and out via file sinks/sources or Network  
sink/sources.

Generally, we really love to help here, on discuss-gnuradio; it might  
still be a good idea not request things that feel like you’re asking us  
to do your job – for example, if you said “I have found a cool  
16QAM-based transceiver using the the constellation receiver [link to  
that], but now I’m stuck with the problem of getting video in and out”,  
I think your questions will attract much more attention.

Best regards, and happy hacking,  
Marcus
