According to one embodiment, a content transmitting and receiving device includes: a content designator receiver receiving a content designator as a uniform resource identifier (URI) over a network; a content transmitter function identifier extracting module extracting a content transmitter function identifier from the received content designator; a content transmitter function identifier comparator comparing the extracted content transmitter function identifier with a content transmitter function identifier stored in the content transmitting and receiving device; a content obtaining method switching module switching between internal transfer of content and external transfer of content over the network based on a comparison result of the content transmitter function identifier comparator; and a content reader reading a designated content from a content accumulating module, wherein if the content obtaining method switching module switches to the internal transfer, the content reader transmits the read designated content to the content receiver function module through the internal transfer.
