    摘要: An information processing apparatus has an authentication & key exchange unit, a contents receiver, a contents decryption unit and a contents confirmation request unit. The authentication & key exchange unit performs authentication & key exchange processing by using a given protocol with the communication apparatus and generates a first key shared with the communication apparatus. The contents receiver receives encrypted contents obtained by encrypting the contents with a second key generated by using the first key and the key information, and the key information attached to the encrypted contents. The contents decryption unit decrypts the encrypted contents by using the first key and the key information. The contents confirmation request unit instructs the communication apparatus to transmit or confirm the key information held by the communication apparatus, when the contents decryption unit decrypts the contents based on the second key firstly generated by using the first key.

    摘要: A device on the sending and playing device plays and outputs a content recorded to a recording medium on the sending side. A device on the receiving and recording side receives the played and outputted content and records it to a recording medium on the receiving side. The device on the sending and playing device erases the content recorded to the device on the sending and playing device based on recording-state information of the device on the receiving and recording side by using the sent played content. Thus, in move processing of a “Copy Once” content, it is possible to prevent the loss of content by the device on the sending and playing side when the device on the receiving and recording and side does not normally record the content.

    摘要: A color video projector as disclosed which includes a cabinet having a depressed top deck, and a mirror carrying L-shape mounting board pivotally carried by a pair of slidably movable arms, guide grooves on the side edges of said top deck and guide pins protruding from the mounting board ride in the guide grooves during withdrawal of the mounting board. The board can only be rocked to its upright position when the arms are fully extended and can only be rocked back to its original position when the arms are fully extended and from which position the mounting board can be pushed back into the cabinet with the mirror above the top deck.

    摘要: A recording and reproducing apparatus includes a file recorder, an interface, and controller which, upon receipt of content file with copy control information, records the content file in the recorder by adding thereto identification information M requesting transfer upon confirmation that a round-trip response time to a destination is not longer than a predetermined time, so that upon receipt of an instruction for transfer of the content file to an external device on the network, the controller determines whether the external device has a function of measuring and determining the round-trip response time to the destination, and in the case where the external device has function of measuring and determining the round-trip response time to the destination, transfers the content file to storage area of the external device, after measuring the round-trip response time and confirming that the measurement is not longer than predetermined time.
