If you like to see what Panasonic announced at the NAB show you can download their press kit here: ftp.panasonic.com/corporate/press/2017_nab_presskit_pr.zip.
Among the newly announced broadcast we got a new 360-Degree Live Camera System With Uncompressed 4K Output (see image on top). Looks like 360-Degree cameras are one of the big things this year at NAB.
