Herelink without cubeboard

Is it possible for my student to use only herelink+battery+hdmisource (like dvd or PC) to show source on receptor; After on videoprojector on local PC (with VLC or ardupilot ?). I don’t want they use other electronic boards to assemble drone before they realise broadcasting for classroom

Thankyou very much
Sorry for my bad english
