I have a new Pelco Sarix camera which is currently connected to a PC which decodes the H.264 video and outputs to a monitor.  I would like to replace the PC with a dedicated decoder.  The only ones I have found are either designed to work with a specific camera or do not support the resoulution and frame rate of my camera (1280 x 720, 30 ips). 
  
Does anyone make a dedicated decoder that will work in this situation?  I'm thinking that it would be more reliable than a PC (hopefully no reboots).  If not, my next choice would be to use a small pc running Linux.  It's hard to find one with enough power to decode high res video though.
