摘要： A content reception equipment for accessing an in-home content transmission equipment from a remote place executes a first authentication process with the content transmission equipment in advance, executes the remote access information sharing process required for access from a remote place, and causes the information on the content reception equipment and the remote access information to be registered in an equipment information table of the content transmission equipment. In the case where the in-home content transmission equipment is accessed by the content reception equipment brought out of home, the content transmission equipment transmits the content to the content reception equipment only in the case where the information on the content reception equipment is registered in the device information table of the content transmission equipment and the second authentication process using the remote access information is successfully executed between the content transmission equipment and the content reception equipment.
