    • The data exchange processing apparatus pertaining to the present invention includes a cryptographic engine unit performing cryptographic processing and verification processing, a stream control unit outputting content while performing cryptographic processing of the content using the cryptographic engine unit, an unauthorized device list update unit verifying an unauthorized device list using the cryptographic engine unit, and a state management unit outputting a permission notification to the unauthorized device list update unit when detecting a low load section of the content according to metadata of the content and processing position of the stream control unit, the low load section being a section in which processing load on the cryptographic engine unit is lower than in other sections. The unauthorized device list update unit, when receiving the permission notification from the state management unit, causes the cryptographic engine unit to execute verification processing of the unauthorized device list.

    • A hinge mechanism for a vehicle door, in which a vehicle body includes a door section having an arm rest extending along an interior portion thereof. The bottom surface of the arm rest contains a recessed section defined along the vehicle interior by a contour line extending along at least a forward portion of the bottom surface of the arm rest. A support arm extends between the door section and the vehicle body to provide primary support for the door section. A control arm with attached cover extends between the door section and the vehicle body for guiding the door section when the door section is opened and closed. The support arm and the control arm are pivotally attached to both the door section and the vehicle body. The control arm and cover have a cross-sectional dimension, when viewed from above, substantially corresponding to the contour line, enabling the control arm and cover to be substantially flush with the contour line when the door is closed.

    • Provided is a content transmission device 310 that can reduce failure of content key confirmation processing during special playback such as fast-forwarding and fast-rewinding. A key management unit 312 generates or updates a key parameter, and stores therein the generated or updated key parameter. The key management unit 312 receives a key parameter from the content reception device 340, and calculates a difference between the key parameter stored therein and the received key parameter. By using the calculated difference, a transmission control unit 313 judges whether or not to change a transmission speed at which an encrypted content portion is to be transmitted, and depending on a result of the judgment, selects one of transmission speeds and transmits the encrypted content portion in accordance with the selected transmission speed. When the difference is greater than a first threshold value, the transmission control unit 313 selects one of the transmission speeds that is slower than a current transmission speed.
    • 提供了可以减少诸如快进和快退的特殊重放期间的内容密钥确认处理的失败的内容传输设备310。 密钥管理单元312生成或更新密钥参数,并在其中存储生成或更新的密钥参数。 密钥管理单元312从内容接收装置340接收密钥参数,并计算存储在其中的密钥参数与接收的密钥参数之间的差异。 通过使用计算出的差异,发送控制单元313判断是否改变要发送加密的内容部分的传输速度,并且根据判断结果选择一个传输速度并发送加密的内容 部分根据所选择的传输速度。 当该差大于第一阈值时,传输控制单元313选择比当前传输速度慢的传输速度之一。
