A method for transmitting shared contents includes: pre-configuring rules for constructing coefficient vectors corresponding to the shared content on each content terminal; by the content source peer, dividing the original content into blocks, constructing coefficient vectors corresponding to the original content according to the rules for constructing coefficient vectors, and combining each original content block with the corresponding coefficient vector linearly to obtain code blocks, with the ID of each code block same as the ID of the corresponding coefficient vector; and by the content receiving peer, downloading the code blocks from the content source peer according to the IDs of code blocks. A system for transmitting shared contents includes: a content source peer and a content receiving peer. The present invention also discloses a content terminal. The present invention may save the transmission bandwidth and improve the content sharing efficiency.
