Switching between video and image on HD210

Hi,

I have written a script that switches between a bmp image and an mpeg video when it receives a command via UDP. Everything works as it should except that there is a varying (from 1 second up to several seconds) delay when switching from the video to the image. During the delay the screen goes black. Is this normal? Switching from the image to the video is almost instantaneous. Is there a way to decrease the time it takes to go from video to image?

Thanks,

Brian

  That extended blackscreen is a bug. This is fixed in the beta release on the web. Or, you can use this 3.1 release:
  
  
  
  Firmware 3.1.83
  
  
  
  Images actually take longer to load than videos. So, you'll get the fastest results with images if the resolution you're using matches the resolution on screen.
  
  
  
  Or, you can just make a video that contains only that one image. That will open the fastest.

  I'll install the 3.1.83 firmware. If that shortens the black screen time it may solve my problem. Because I'm creating the images on the fly in another program it isn't possible for me to turn them into single picture videos.
  
  
  
  Is there a difference in the time it takes to load images of different formats? Do bitmaps load faster than jpegs, for instance? If so, which is the fastest loading format?
  
  
  
  Thanks,

  Yes,
  
  
  
  I believe bitmaps load the fastest.
  
  
  
  What's the resolution of the images you're loading?

  The images are 800x600 which is the resolution of the monitors I'm using.

  The new firmware makes the transitions quick enough and there's no black screen now. My problem is solved.
  
  
  
  Thanks!

  i can speak of a hd2000: jpgs loads way slower than uncompressed (bmp, png). with bmp i can load videos and pictures in 1 second. for static colored pictures i use short videos instead of pictures.
