摘要： A disk tray includes a storage concave portion that is to store a disk-shaped recording medium. The disk tray is supported by a carrying mechanism to thereby be carried from an opening portion provided to a front face of an apparatus main body (main body of an apparatus for storing the disk tray) over a range between the inside and outside of the apparatus main body, the disk tray comprising. The disk tray further includes a buffer material provided on a peripheral surface of the storage concave portion that stores the disk-shaped recording medium. Thereby, the disk-shaped recording medium, such as an optical disk, is restrained from being crushed even when being rotationally driven at high speed.

摘要： It is an object of the present invention to provide a contents reproducing device which can perform an intermittent operation with improved responsiveness to user request. The contents reproducing device according to the present invention includes: an input operation unit (1100), a system state managing unit (1210), a system information storing unit (1220), a contents reproduction control unit (A) (1230), a state after next candidate extracting unit (1240), a contents reproduction control determining unit (1250), and a contents reproducing unit (1300). The contents reproduction control determining unit (1250) determines whether or not a candidate related to the contents reproduction control is in the state after next candidates extracted by the state after next candidate extracting unit (1240). Therefore, the contents reproducing device according to the present invention can improve responsiveness to the user request by shortening the cycle of the intermittent operation of the contents reproducing unit (1300) when it is determined that there is a possibility that a user request related to the contents reproduction control is inputted, and by lengthening the cycle of the intermittent operation of the contents reproducing unit (1300) when it is determined that there is no possibility that a user request related to the contents reproduction control is inputted.

摘要： A packet compressor 12 operates under a reliable mode or an optimistic mode. A mode determination unit 31 counts the number of ACK packets or NACK packets received by a unit time X by an ACK/NACK packet receiver 14. When the counted number of NACK packets is larger than a predetermined value Y, the mode determination unit 31 switches the operation mode of the packet compressor 12 to the reliable mode. When the counted number of ACK packets is larger than a predetermined value Z, the mode determination unit 31 switches the operation mode of the packet compressor 12 to the optimistic mode.

摘要： In synchronization of a conventional AV system, when a stream as the master stops, a system clock cannot be corrected for synchronization. Since the correction is consistently performed even when an error is small, overhead of correction is large. On the other hand, when an error is large, sharp correction causes a feeling that something wrong. In the present invention, when the stream as the master stops, previously registering the degree of priority regarding the master, consideration of a corrected period or a previous error for the system clock, or transmitting a stream containing information regarding the master can allow for other process to serves as the master. Accordingly, it is possible to provide a method for synchronization with maintaining correction of the system clock. When a corrected error is large, gradual correction or reference can provide a system with normal feeling. Furthermore, when an error of correction is small, omission of correction or reference can provide a system with less overhead.
