The "Transmission" video is using TunesToTube.com.
It is a bunch of numbers being recited (though I don't know the significance of the static image):
"053 050 046 049 056 050 049 044 032 050 048 046 057 057 054 053" It then pauses and repeats for exactly 5 minutes.
Translated (by others in this thread), it turns into 52.1821, 20.9965, which brings you to the number 18, in Poland. It also links to this Google Drive folder titled "Latest Discoveries":
This has a few photos of statues of the Buddha and a couple of temples. I find the photo that looks corrupted the most interesting, as I think there is data hidden in there (similar to 4chan.js if you've ever heard of that).
The file names of the photos are shrine.jpg, statue.jpg, spire.jpg, pillar.jpg, and cave.jpg.
