摘要：
A content transmitting apparatus includes a content transmitting unit (111) that IP packetizes content to be transmitted through a communication network (101), and an encapsulating unit (112) that encapsulates the content IP packetized by the content transmitting unit (111) to generate a transmission packet to be transmitted through a broadcast network (102) for digital broadcast media. The content transmitting unit (111) and the encapsulating unit (112) transmit plural content items by IP multicast. The content transmitting unit (111) adds, to a header of the content to be IP packetized, information concerning a condition of a receiving side node of the content.
