I have an ancient box (Scientific Atlanta, Explorer 8300HD). It has co-ax and HDMI outputs, but the HDMI got fried a long time ago by lightning. No big deal, I'm content with analog. BUT I'd like to be able to "ghost" the co-ax output to a second TV in another room, without using a long co-ax run. I don't want any kind of second cable box, because I'm *not* trying to have plural TVs operate independently of each other -- I'd just like the remote TV to duplicate whatever is happening on the "primary" TV.
Is there any kind of gadget for doing this? -- for example, [cable coax output] to [WiFi-networking-transmitting-gadget], then receiving the signal on the (WiFi-capable) Blu-Ray player attached to the second TV, or on a WiFi-receiving-gadget which attaches to the second TV's co-ax input.
