Up front you have that HDMI connector jack on the white wall plate. You connect the output from the Bose sound system to that jack. Your Blu-Ray player and satellite receiver all get connected to the input jacks on the Bose. You use the remote on the Bose to select whichever input source you want to view and it sends that signal out to the HDMI jack on the wall plate.
From there, an HDMI cable goes down into the basement and connects to a 1x4 HDMI distribution amplifier. The four outputs from this amp go to each of the four TV sets so whatever your Bose has selected will appear on all four of the TVs. Note that this amplifier is powered by a 120 volt wall wart so check to see that it didn't come unplugged. The only other thing is to make sure your TV is set to look at the correct input, via the TV remote's "Source" button.
The bedroom TV is a bit different. It too has multiple input sources that can be selected. One source is the output from the Bose system as previously mentioned. The second source is directly from your bedroom Blu-Ray player or from a second (bedroom) satellite receiver or DVR. Again, use your TV remote to toggle between the various sources. In my case, and most likely in yours too, the bedroom TV only has two HDMI inputs so you'll need to use component video for the third source, either the bedroom receiver or Blu-Ray player.
