    HI Friends,
    
 
    WE are group of master students building small unmanned aerial vehicle(uav). We are planning to use  any of ADSP BF5XX series to perform certiain onboard image and video processing task in realtime on a flying platform. The input images and video for realtime processing is obtained from camera placed on the uav. Our intention is that, the captured input image and video has to be processed using ADSP BFXX( say applying some image processing algorithm on those image and video). Once the onboard processing is done, the processed video have to be transmitted to ground station which 500m away from the flying vehicle. Following are my doubts ??
    
 
     1.  Is it feasible to implement entire mission using ADSP BF5XX series ??
    
 
     2. If Yes, We are planning to use  2.4GHz 500mW audio/video TRANSMITTER. Is it possible to interface this transmitter with any of ADSP BF5XX    series?? I attached the video transmitter pic for ypur reference.
    
 
    Thanks in advance for replying my query. Looking forward for your valuable suggestion.

      Hi,
      
 
      The BF561 EZ Kit Lite has an ADV7179 video decoder that supports NTSC/PAL.  You can connect any camera, such as the one you showed, that provides NTSC/PAL through an RCA connection.  Likewise for the output, there is an ADV7183A which is an NTSC/PAL/SECAM Video decoder.  The output is also through one of the onboard RCA jacks.  I suspect you can connect the output from this to your transmitter.
      
 
      Higher resolutions are not supported on the BF561.
      
 
      There are two examples for video input-output that comes with the VDSP++ developement tools.  You can take a look at those.  It'll give you a good starting point.  Once you grab the video frames, you can start processing them.  The examples can be found in directories:
      
 
      <VDSP++ installation>/Blackfin/Examples/ADSP-BF561 EZ-KIT Lite/Video Input-Output (C)/   and
      
 
      <VDSP++ installation>/Blackfin/Examples/ADSP-BF561 EZ-KIT Lite/Drivers/PPI/VideoInOut/
      
 
      Regards,
