A transfer mechanism includes: a tray that includes a placement surface section on which a recording medium is placed, and retention means for keeping hold of the recording medium placed on the placement surface section, and is moved and rotated across an insertion/removal position at which the tray is faced toward the outside of a device body with the placement surface section being substantially horizontal and a recording/reproduction position at which the tray is housed in the device body with the placement surface section being substantially vertical; a clamp member that is supported inside of the device body to allow a main surface section thereof to move and rotate across a substantially-horizontal direction and a substantially-vertical direction, and clamps, with a support mechanism, the recording medium moved and rotated to the recording/reproduction position; and a movement mechanism that moves the tray.

When recording stream data, index information and time correction information are recorded in correspondence with the stream data. The index information specifies a position of an invalid section in the stream data. The time correction information specifies a time which, supposing that a PCR included in the invalid section was able to be got, a time clock would have shown in synchronization with the PCR. When reproducing the stream data recorded together with the time correction information and the index information, at a position where the invalid section ends, the time clock can be set to a time intended by a broadcasting system, by referencing the index information and the time correction information.

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.
摘要:
In a normal operation state, a connection management section writes data transmitted from a first processing section to a data temporary storage section and reads data to be received by a second processing section from the data temporary storage section. Upon receiving control signals which instruct a change of the subject of processing, the first processing section and the second processing section output a transmitting-end clear request and a receiving-end clear request, respectively. The connection management section reads data from the empty data storage section after a transmitting-end clear request is received and until a receiving-end clear request is received, and writes data to the empty data storage section after a receiving-end clear request is received and until a transmitting-end clear request is received.
摘要:
A data transmission apparatus for sequentially transmitting data in units of packets each containing transmission data to the receiving end, comprises: a reception unit for receiving the transmission data as an input signal; a packet formation unit for receiving the transmission data received, and forming an uncompressed packet in which predetermined transmission data is stored as uncompressed data, and a compressed packet in which at least a portion of transmission data that follows the predetermined transmission data is compressed and stored as compressed data.

A stream data recording device is provided for recording stream data on a recording medium. The stream data recording device includes a stream reception/analysis unit (101), for acquiring stream data from reception data; a missing portion detection unit (102) for detecting a missing packet portion in the acquired stream data; a section information generation unit (103) for generating time information specifying the duration of the unreceivable section including the packets whose missing portion has been detected and position information specifying the position of the unreceivable section in the stream data; and a recording unit (105) for recording the acquired stream data, the generated time information and position information on the recording medium. Thus, even if the recording-target stream data is missing a portion during reception of the stream data, the data can be correctly played back from the seek time specified by a user.

The packet formation unit forms compressed data to be stored in a compressed packet, on the basis of the transmission data of the uncompressed packet and the reference information stored in the reference information management unit. Therefore, the number of packets to be discarded at the receiving end due to an error which has occurred in the radio section is reduced, whereby the quality of data transmitted in the transmission path including the radio section is improved.
摘要:
A fuel tank has a tank body and a fuel inlet projecting upwardly from the tank body. The fuel tank includes a cylindrical member extending into the tank body, a canister, and a discharging passage in communication with the canister housing an adsorbent for absorbing fuel vapor from the fuel tank. A space between an outer circumferential surface of the cylindrical member and an inner circumferential surface of the fuel inlet is hermetically sealed by a seal. The cylindrical member has a passage for communicating an inside of the cylindrical member with a portion of an outside of the cylindrical member that is lower than the hermetically sealed space. The passage allows air in the tank body to enter the fuel inlet when fuel overflows from the fuel inlet, thereby inhibiting flow of fuel into the canister through the discharging passage.
