The recording apparatus has a management section which manages the restrictive information, and a restriction section that adds a restriction to at least one of a next copying of the same content as copied last or each piece of the recorded content that provided a source of the copying.

Transmission/reception system, recording apparatus and method, providing apparatus and method, and program

A control machine which uses a data amount stored in an FIFO as a trigger and allows a DMA transfer to be started according to a capacity of the FIFO allows a control machine for preparing for the DMA transfer to start to prepare a command and the like for the DMA transfer. The control machine for preparing for the DMA transfer issues the prepared command to a control machine for transferring DMA data, so that a process according to the command is started. At the time of the DMA transfer, a burden on a host CPU is reduced.

Information processing apparatus and method for handling packet streams

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.

Data processing apparatus and method with packet parsing

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.

Information transmitting method, information processing method and apparatus, and information recording and reproducing method and apparatus

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.

Information transmitting device and method, information terminal device and information terminal receiving method, digital broadcast receiving device and method, and output time calculating device and method

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.

Recording and reproducing apparatus, and variable speed reproducing method using same

In recording a stream in a storage device, a packet containing a start part of encoded image data subjected to intra-frame coding is identified from the input stream of packets. Presence or absence information of the start part of the encoded image data subjected to intra-frame coding is added to the packet on the basis of an identified result. The added presence or absence information of the start part is counted in a recording unit, and the count result is added in the recording unit onto the storage device. The number of start parts of the encoded image data subjected to intra-frame coding in every recording unit, together with the recording unit, can be recorded on the storage device. In playback, the number of start parts recorded in a recording unit on the storage device is detected to identify the recording units to be reproduced.

The receiving apparatus determines whether the copy restriction code allows for one or no copies to be made and controls the outputs of the receiving apparatus accordingly.

Data processing apparatus and method for preventing unauthorized copying

Data processing apparatus and data processing method, and recording medium

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.
