control packets issue in dsp builder

Honored Contributor I



I am working on video and image processing project. 

I am using quartus II v6.0 and dsp builder. 

I have used deinterlacer, chroma resampler, color space converter and scaler megacore function between two avalon streaming interfaces as it is shown in the figure.  


I want to process video data packets only, so I have to import a custom logic block(vhdl or verilog file) in between deinterlacer and chroma resampler, but the problem is I donot know before the video packets either the control packets are coming or not.  

How Custom logic block(vhdl or verilog file) can differentiate between video and control packets??????  

I donot know how to handle this issue of control packets!!!!!!!! 


If you have any idea please let me know. 

Thank You
