The　development　of　digital　media　technology　provides　more　possibilities　for　the　expression　of　information.　For　example,　the　visualization　technology　of　information　can　transform　complex　intangible　cultural　content　information　into　intuitive　and　understandable　pictures.　Various　technologies　such　as　human-computer　interaction　technology,　Internet　technology　in　digital　media　technology　can　improve　the　interactivity　and　user　experience　in　the　dissemination　of　intangible　cultural　heritage,　and　play　a　unique　role　in　the　dissemination　and　popularization　of　intangible　cultural　heritage.　Based　on　the　combination　of　museum　and　digital　media,　this　paper　presents　the　transmission　of　intangible　cultural　heritage　under　the　background　of　digital　media.　In　the　end,　an　improvement　idea　will　be　put　forward,　based　on　the　rational　use　of　public　space,　using　some　of　the　digital　media　as　a　good　communication　medium,　optimizing　the　current　museum　education　communication　channel,　and　developing　the　digitalization　of　cultural　heritage　that　can　be　accepted　by　the　general　public.　©　Springer　Nature　Switzerland　AG　2020.
