Abstract: A transport stream (TS) is recorded and the recorded TS is reproduced simultaneously. An input PID parser extracts the first packet only to be recorded, the second packet to be recorded and to be used for controlling, and the third packet to be used only for controlling from among the TS packet that constitutes the TS supplied from a descrambler. The first and second packets are supplied to a receiver and supplied to a hard disk drive (HDD) for recording. The second and third packets are supplied to an MUX. On the other hand, the TS packet stored in the HDD is read out and supplied to the MUX by way of an output PID parser. The MUX multiplexes the second or third packet supplied from the input PID parser and the TS packet read out from the HDD, and supplies the multiplexed packet to a CPU that controls a descrambler or the like.

Abstract: For example, in case of distributing contents by BS broadcast and recording a transmitted TS stream into a storage device, even if the stream has been encrypted, a trick play can be easily performed. A start marker packet and an end marker packet are sent just before and just after the start of an I picture. A unique PID is written in each of the start marker packet and end marker packet. Upon reception, a video packet of the I picture is identified by identifying the start marker packet and end marker packet. Upon recording, a TS packet of the I picture is detected from the start marker packet and end marker packet and marked. Thus, upon reproduction, a cluster including the TS packet of the I picture is known and a trick play can be performed by reproducing the I picture.

Abstract: It is an object to deliver contents in a different time from a real time through a digital artificial satellite and reproduce a program at a correct time, thereby transmitting information about contents for a long time by utilizing a limited time or transmitting information about contents in a small band. There is prepared a dummy packet including an adaptation field having the value of a dummy PCR for restoring a real time and time ratio information of a transfer time and the real time. During receipt, time information during output is obtained from the dummy PCR and the time ratio information. The time information during the output is added as a time stamp to a TS packet and is stored in a storage device such as a hard disk drive. During reproduction, data are read from the storage device by referring to the time stamp added during the recording. Consequently, the information about the contents transmitted in a different time base from the real time can be reproduced in a correct time base.

Abstract: When a variable speed reproduction of a low-time speed like an overtaking reproduction is executed by using an MPEG2 stream, deterioration in picture quality is prevented and low costs are realized. An arrival time of an input TS packet is added by an input counter and the resultant TS packet is recorded onto an HDD. When the TS packet is reproduced from the HDD, the arrival time is extracted from the reproduced TS packet. The arrival time is compared with an output time. When the arrival time reaches a time corresponding to the output time, the TS packet reproduced from the HDD is output. The time base of an output counter is fluctuated by a variable speed counter, thereby enabling the time base at the time of reading out the TS packet from the HDD to be slightly shifted from the time base at the time of recording the TS packet onto the HDD. Thus, a micro variable speed reproduction can be performed. The overtaking reproduction can be performed by such a micro variable speed reproduction.

Abstract: A knowledge information managing apparatus manages knowledge information to reuse information of analytical details and a process which have led to information as a fruit. The knowledge information managing apparatus accumulates dialogue streams including the contents of a series of message data exchanged between persons involved in a business through a network. The knowledge information managing apparatus also sequentially accumulates objects required to perform the business in a process from generation of the problem to a conclusion about the problem, in a state in which the objects are required. The knowledge information managing apparatus relates a desired one of the accumulated dialogue streams and a desired one of the accumulated objects to each other in response to a relating request, and outputs information about the desired dialogue stream and the desired object which are related to each other in response to a related information acquiring request.

Abstract: A transport stream is received and recorded, and the recorded transport stream is reproduced normally. A cycle timer generates a time stamp based on a clock generated by means of a clock generation circuit that is independent of the system clock generated by means of a built-in PLL of an AV decoder, a receiver adds the time stamp to a TS packet, and the TS packet is recorded in a hard disk. On the other hand, a transmitter supplies the TS packet read out from the hard disk to the AV decoder by way of a switch, MVLink-IC, DEMUX, and FIFO memory at the timing so that the time interval between adjacent TS packets is coincident with that of the time when it was received based on the time stamp added to the TS packet.

Abstract: An apparatus for receiving a digital broadcast signal includes a tuner operable to select a desired transmission channel over which to receive the digital broadcast signal and demodulate a transport stream which is transmitted over the selected transmission channel. The receiving apparatus also includes a demultiplexer operable to extract a desired program from the demodulated transport stream; an interface operable to transmit the demodulated transport stream to, and receive a reproduced transport stream from, a reproducing apparatus; and a discriminator operable to determine whether the reproduced transport stream contains a multiplexed plurality of programs. A predetermined process is performed on the reproduced transport stream when the discriminator determines that the reproduced transport stream contains the multiplexed plurality of programs.

Abstract: An electronic apparatus includes a CPU, a ROM, a RAM, an input port, a data bus, an address bus, a patching portion address register and a patching interrupt vector register which are connected to the data bus. A comparator compares a coincidence of the address stored in the address register with an address on the address bus and, in response thereto, supplies an interrupt to an interrupt control portion of the CPU. The interrupt control portion of the CPU is also supplied with other interrupts, for other processing. Further, an external storage device, connected to the input port, supplies a program bug patching information to be stored into the RAM. The RAM includes a stack area in which, during interrupt processing, there are saved data written in the address register and the patching interrupt register. Thus, patching of program bugs can be carried out even during an interrupt.
