In order to provide a recording and reproducing device that allows a user to select and manage arbitrary play lists, a unit of management for managing all registered play list information and an upper management hierarchical level are added. The unit of management is adapted to be handled on the same level with unified information that indicates a reproduction range of all AV data. User-defined unified information is adapted to be handled on the added management hierarchical level. The user-defined unified information is formed to allow arbitrary reproduction ranges contained on a lower hierarchical level to be registered.

Editing method and recording and reproducing device

A digital information recording apparatus includes a recording circuit for recording information of a retention period included in the digital information and indicating a period for permitting the digital information to be held in the recording medium, starting with a time at which the digital information is recorded on the recording medium; and information of a playback permission period included in the digital information and indicating a period for permitting the digital information to be played back starting with a time at which the information is reproduced initially following recording of the digital information on the recording medium, permitting temporary recording or copying for the information permitted for 'copy never' or 'copy one generation.'

Digital information recording apparatus, reproducing apparatus and transmitting apparatus

A content transmission device for transmitting a digital content to other device connected via a network, including a receiving unit that receives the digital content accompanied with a piece of copy control information indicating a condition of restricting the digital content from being copied, a communication processing unit that transmits and receives the digital content or control commands to and from the other device, a connection determining unit that determines whether the other device is present on an intra-residential network connected by the content transmission device, and a control unit that controls the receiving unit, the communication processing unit, and the connection determining unit, in which the control unit does not output the digital content received by the receiving unit from the communication processing unit to the other device in a case where the other device is determined not to be installed at an inside of a residence.

Content transmission device and content transmission method

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.
