I pretty much agree with the responses here, but just to throw a wrinkle into the thought process, with respect to "re-broadcast", I agree completely, but with respect to "re-transmission", I'm not so sure. There are some significant differences between the terms broadcast and other forms of transmission or communication. Broadcast has historically referred to putting up a signal not to a specific recipient, but instead to any and all that are able to receive it. For example, hams in general, with some exceptions, are not permitted to broadcast, but are instead supposed to be doing ham to ham communication.
Of course, this doesn't change anything relative to copywrite, but it's generally understood that we have the right to receive these FTA signals, and to display the video we all re-transmit it in some way, just to get it to our TVs, either by sending it down an HDMI or A/V cable to our TV or streaming it to a Roku or Azbox, etc. So I don't think that simply re-transmitting it is a problem, I think it depends on who the recipient's are. Ie, if you're streaming it to your TV for your wife to watch, I don't see a problem, but if you're streaming it over the internet via UDP for the general public to view, then that's obviously a problem, because that's broadcasting. So the question is where do you draw the line. Streaming via a wireless net to your brother two houses down the road? Streaming to your best friend across town via the internet. Streaming an NFL game to a group of football fans in a club you belong to? Streaming to some company to demonstrate some capability like this? Clearly, the two extremes, ie wife vs general public are well defined as OK and NOT OK, but I don't have a clue where the line would be drawn for intermediate senarios. My guess is that if there is just one recipient that it might be OK, but if there are multiple recipients, even if all at one location, I would think that wouldn't be OK.
Anyway I agree with the above responses, but there are some gray areas depending on who you're sending it to, and how.
