The invention relates to a method for acquiring network audio files and video files, which comprises a video-on-demand list unit, a reading-on-demand device and a network server, wherein image codes representing destination files are preset in the video-on-demand list unit and the reading-on-demand device can read the image codes. The method of the invention is characterized by comprising the following steps: a table of information on the corresponding relation between decoding information codes of the image codes and the attribute information of the destination files is established; connection between the reading-on-demand device and the internet is established; an image reading unit of the reading-on-demand device acquires the image codes set in the video-on-demand list unit; a digital processing unit of the reading-on-demand device receives the image codes acquired by the image reading unit and decodes the image codes to acquire the information codes; the digital processing unit acquires the attribute information corresponding to the information codes according to the table of information; the digital processing unit of the reading-on-demand device sends a connection instruction to a network module according to the attribute information of the destination files corresponding to the information codes; and after the network module receives the connection instruction, the network module connects the network server to acquire the destination files. The invention enables users who are unable to surf the internet or unwilling to surf the internet to acquire the network audio and video destination files quickly and conveniently.
