摘要

A method and an apparatus for transmitting contents, a method and an apparatus for receiving contents, and a content service system are provided. The method for transmitting contents includes converting first contents including distortion part contents in which at least an area of a specific part of source contents is subjected to distortion processing into a transmittable type through a transmission network to generate a first transmission signal; converting any one the source part contents that are the part contents corresponding to the part of the source contents and differential information between the source part contents and the distortion part contents into a transmittable type through the transmission network to generate the second transmission signal; and transmitting part information indicating the first transmission signal, the second transmission signal, and the part through the transmission network.
