I&amp;#x27;m curious to see how DJI competes with that on a digital video.&lt;p&gt;The good news is that you can find that out right now. DJI HD FPV has been available for over a year, this is just their first drone offering in the category.&lt;p&gt;The short answer is that it degrades very gracefully. They have what they call &amp;#x27;focus mode&amp;#x27;, where the edges of the video lose quality before the middle (where the data matters the most). Once you&amp;#x27;ve used up that signal degradation threshold the rest of the frame slowly degrades to a lower bitrate, and then after that latency starts rising.&lt;p&gt;After flying analog for 5 years it only took me about 1 day to strongly prefer the DJI FPV video solution. The range is far better, and the video is mind-blowingly clear when compared to analog. On anything but my racing specific drones I have been installing the DJI HD FPV system instead of normal analog gear.</text></comment>

I&amp;#x27;m curious to see how DJI competes with that on a digital video.&lt;p&gt;Waiting for a degradation tolerant codec.&lt;p&gt;Old MPEGs were, as they had broadcast use in mind, but even 264 blow them out of the water on compression nowadays.&lt;p&gt;Loss tolerant codec + modern channel coding will likelly outrange analog for quality picture</text></comment>
