    Abstract: PROBLEM TO BE SOLVED: To provide a stream control apparatus, a stream reproducing method, and a video recording and reproducing system with a small scale circuit configuration that can reproduce a stream including video at a high speed via a network. SOLUTION: A video recording apparatus 2 receives a stream, and the stream control apparatus 3 attaches reference data to the received stream by each TS packet and stores the resulting stream to a medium 4. When receiving a high speed reproduction request whose reproduction speed is instructed, the stream control apparatus 3 refers to the reference data, extracts a PES packet including I pictures from the medium 4, adjusts a time stamp, applies format shaping to the stream in the unit of TS packets and thereafter transmits the stream to a reproduction apparatus 5.

    Abstract: PROBLEM TO BE SOLVED: To provide a transmission / reception system capable of readily carrying out error corrections. SOLUTION: An RTP-packetizing section 83 collects TS packets to which error correction parity data are attached by an error correction attachment section 82 into a preset number, attaches an RTP header to the collected TS packets, sequentially assigns the sequence numbers incremented by one, each to the TS packets to produce RTP packets and supplies them to a MAC frame processing section 84. Thus, an error correction section 984 uses the received RTP packets, on the basis of the sequence numbers of the RTP packets, to carry out error corrections, thereby recovering packets missing in a communication path. The present invention is applicable to transmitting / receiving systems for transmitting / receiving AV data through radio communication. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PURPOSE:To obtain a time domain filter which prevents occurrence of erroneous data by providing a delay circuit on the line coupling of the output terminal of a comparator and a D-type FF. CONSTITUTION:Variation of the output B of a comparator 1 is detected by means of a pulse generating circuit 2 and the output D of a monostable multivi brator 4 is inverted by the short pulses C outputted from the circuit 2. The output D of the vibrator 4 is returned to the original state after a prescribed time. In case the output B of the comparator 1 is inverted by a noise when the output D is returned to the original state, the inverted output B is inputted to a D-type FF 5 as an output B' after it is delayed by a prescribed time by means of a delay circuit 3. As a result, the FF 5 holds the output D before inversion of the comparator 1. Moreover, if the output B of the comparator 1 is inverted immediately before the output 4 of the vibrator 4 returns to the original state, the vibrator 4 is triggered. Therefore, the FF 5 does not hold the inverted output of the comparator 1. The output E of the FF 5 is led to a pulse generating circuit 6 and a monostable multivibrator 7 is triggered. As a result, pulse signals are outputted as read data F.

    Abstract: PURPOSE:To attain highly accurate tracking control by interpolating servo information based on a servo signal detected at a data track by using servo information based on a servo signal detected at a servo track. CONSTITUTION:The sector length (the length of data area D i.e. interval between servo areas S) of data tracks TRD (tracks TR00-TR239) is set longer than conventional. And, servo information in the intermediate position between servo areas on the data tracks TRD is obtained by operating an interpolation based on servo information obtained from a servo track in the outer vicinity and, when necessary, obtained from a servo track in the inner vicinity. The tracking control is executed based on thus obtained imaginary servo information. As a result, a highly accurate control can be attained even in case the sector length of the data track TRD is long.

    Abstract: PURPOSE:To reduce the size, the weight and the cost of a disk device by ejecting a disk-shaped recording medium by using effectively a disk driving motor. CONSTITUTION:In case of the ejection in an arrow mark a' direction, an auto- eject device 16 drives the disk driving motor 7 so as to rotate in the reverse direction of a positive rotation at the time of the recording and the reproducing of the disk 1, according to an eject instruct signal, and drives a gear 17, formed at the lower part of a disk table 5 in one body, i.e., an eject driving body so as to rotate reversely in the arrow mark b' direction, and establishes an eject mode. At that time, when an outer gear 18, constantly engaging with the gear 17, is driven to rotate reversely in the arrow mark d' direction, a one-way clutch 20 comes into a transmitting state, and a inner gear 19, being driven to rotate in the same direction by the output from the one-way clutch 20, performs an eject action. Thus, the disk device can be made small and light and low-cost.

    Abstract: PROBLEM TO BE SOLVED: To provide a data processor, a data processing method, and a data transmission/reception system which enable received stream data to be surely processed and outputted without dropout of data. SOLUTION: A CPU 12 uses as an initial value a time stamp added to the first packet of received MPEG-TS data to activate a counter 121 of 27MHz on the basis of an oscillator 14 and compares its counted value with a time stamp of each packet and permits output of the packet from a FIFO buffer 13 when the counted value is equal to or larger than the tim stamp. In this case, a counting speed of the counter 121 is adjusted in accordance with the amount of data stored in the FIFO buffer 13. COPYRIGHT: (C)2006,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device having a function to notify a user of the fact that an optical disk, which is unlawfully copied, is not reproducible. SOLUTION: When a cipher detecting means 4 can not detect a cipher signal from the reproduced data read from an optical disk and an electronic watermark detecting means 5 detects an electronic watermark signal, an error signal is outputted from a signal outputting means 6. When a signal reproducing means 7 receives the signal, an unauthorized display signal outputting means 8 outputs a display signal to indicate it is impossible to conduct a reproducing because the signals recorded on the optical disk are unauthorized ones.
