A data transmission apparatus for relaying data transmitted from the transmitting end in units of packets, each packet having additional information relating to its sequence number, priority and data reproduction time, comprises: a receiving unit for receiving packets transmitted from the transmitting end; a priority decision unit for deciding the priority of each of the received packets; a retransmission packet storage unit for storing packets the priorities of which are equal to or higher than a predetermined value, as retransmission packets, on the basis of the priority of each packet decided by the priority decision unit; a retransmission instruction receiving unit for receiving a retransmission request from a terminal at the receiving end; a retransmission decision unit for deciding whether retransmission of the packet for which the retransmission request has been made should be performed or not, on the basis of the retransmission request and the storage status of the retransmission packets in the retransmission packet storage unit a transmission queue management unit for setting the transmission order of the received packets and the packets which have been decided as packets to be retransmitted, on the basis of additional information which is given to each packet; and a transmission unit for transmitting the data of these packets in the transmission order set by the management unit. Therefore, the transmission quality in a radio section in real-time transmission is improved and, further, the number of retransmission times is reduced.

In a data transmission/reception apparatus 11, a data transfer is performed by a pipeline technique between N processing sections Pd—1 to Pd_N. The data transmission/reception apparatus 11 includes (N−1) or more intermediary sections 21, each having a transmission/reception control section 23 for controlling data transmission/reception and a buffer 27. The intermediary sections 21 interconnect adjoining first and second data processing sections Pd—1 and Pd—2 to allow data obtained through the data process performed by the first data processing section Pd—1 to be transmitted to the second data processing section. A transmission API 35a in the first data processing section Pd—1 transmits data to the second data processing section Pd—2. A reception API 37b in the second data processing section Pd—2 receives the data transmitted from the second data processing section Pd—2.

A disc transport member whose width for mounting of a disc is smaller than the diameter of the disc is inserted into and removed from a drive main body while being mounted with the disc. A disc protection member is provided, so as to face the disc, on an edge of the disc transport member or a region close thereto on a side where the disc that is mounted on the disc transport member projects.

A data processor comprises a decoder for decoding the compressed data into decoded data while reading the compressed data from a first data storage, a second data storage for storing therein the decoded data, a DA converter for converting the decoded data into an analog signal while reading the decoded data in real-time, a first controller for controlling the decoder to perform intermittent operation by executing a process between reading the compressed data and storing the decoded data at a speed faster than real-time, a clock/power controller for making a restriction of power consumption of the decoder and the first controller in downtime of the intermittent operation, a second controller for outputting a control signal in accordance with the storage state of the decoded data, and an activation controller for controlling the clock/power controller to lift the restriction in response to reception of the control signal.

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), acquiring stream data from reception data, a a missing portion detection unit (102) detecting a missing packet portion in the acquired stream data, a section information generation unit (103) 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) 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.
