Miscellaneous something for you to explore...
The use of Apple TV connected to your TV (I used HDMI connection between these two).
The TV has a Wifi connection to my computer's router.
Import your video file into iTunes, then set Apple TV to "Computer" and, with iTunes opened (File Menu/Home Sharing enabled) on the computer, view your video in iTunes on the TV. iTunes typically accepts H.264.mov files. See Publish+Share/Computer/QuickTime.
There is probably lots more written about this online. Above is just starter suggestion.
More later if interested.
