Cultural programs of HNTV satellite channel are analyzed with the theory of medialogy and remediation,and the result shows that the innovative theme architecture of"online entertainment+tradition",the immediacy production of"real scene+AR"and the hypermediacy communication of"real scene+AR"are the keys to its success,but problems exist in the process of remediation including cultural communication dominated by digital media,cultural symbols abused in cultural programs,and homogeneous short video communication.Excellent cultural programs should be adopted to excavate traditional cultural content,combine traditional materialized media with new media technology,and give full play to the status of cultural actors so as to disseminate traditional culture with cultural programs.
