Abstract: When an audio signal is reproduced from a video tape (1) on which audio signals having two kinds of effective samples, i.e. (800 and 801), in one field and forming 4,004 samples in five continuous fields are recorded on tilted tracks thereof, signal processing by which the samples reproduced by at least the first reproduction operation are all outputted from among the audio signals obtained by reproducing at least twice video signals of the same field during a speed change reproduction mode in which reproduction is made at least twice for an arbitrary field by a dynamic tracking head (2A), and by which samples by other reproduction are adaptively controlled so that the total sample number of five fields becomes not greater than 4,004 samples, is carried out by a deshuffling circuit of a first audio processing portion (21).

Abstract: PROBLEM TO BE SOLVED: To appropriately protect protection information by defining an appropriate security level. SOLUTION: A key management server 14 correspondingly records a value uniquely identifying equipment and a code constituted of a plurality of layers for forming an encryption or decryption key and transmits the code to a recording device 11 or a reproducing device 12. The recording device 11 generates the encryption key from the received code, encrypts contents using the key and records them on a recording medium. The reproducing device 12 generates the decryption key from the received code and decrypts contents read from the recording medium using the key to define the appropriate security level, thereby appropriately protecting the protection information. The information processing system may be applicable to a recording and reproducing system. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To make it possible to improve a device which carries a security chip in terms of cost and circuit packaging. SOLUTION: Inside the security chip 23, a pair of public keys consisting of a public key 54 (public keys from 54-A to 54-D in a figure) to be used in encryption processing by prescribed public key cryptography, and a private key 61 to be used in decode processing corresponding to the encryption processing are mounted on a nonvolatile memory 32 (private keys from 61-a to 61-d in a figure) in which a plurality of pairs can be stored. On this occasion, each of public keys and private keys is attached with an ID which uniquely specifies itself, and is managed by the ID. For example in the figure, IDs of public keys from 54-A to 54-D are set from A to D respectively, and IDs of private keys from 61-a to 61-d are set from a to d respectively. This invention is applicable to various devices which carry security chips. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To allow a transmitter side to send transmission data as designated by a receiver side by allowing the receiver side to designate contents of the transmission data to be received to the transmitter side through only an ATM communication channel. SOLUTION: Data RE422-ch1 and data RS422-ch2 are used for the transmission of control data or the like using an RS422 between sound and video processing units connected respectively to data transmitters at a transmitter side and a receiver side. An ancillary data area corresponds to the line unit of the audio and video data of the D2 system, and AES/EBU data whose word width is converted into 8-bit width and video data of the D2 system are stored in a video data area in the unit of lines.

Abstract: PROBLEM TO BE SOLVED: To transmit audio video data adopting the D2 system or the like in compliance with the AAL1 protocol of the ATM system. SOLUTION: Only data included in an ancillary data area and a video data area are extracted from sound and video data of the D2 system at a data rate of 143Mbps and the data quantity is reduced to be at a data rate 132Mdps or below in compliance with the AAL1 protocol for an ATM communication channel. The sound and video data of the D2 system whose quantity is reduced are multiplexed together with other prescribed data into a prescribed transport packet in the unit of lines and the pocket is sent to the ATM communication channel. A receiver side adds unrequired date to the received sound and video data to reproduce the video and sound data of the D2 system and the receiver side outputs them synchronously with a regenerated synchronizing signal SYNC.

Abstract: PURPOSE: To accommodate a digital video signal on an ATM line with efficiency. CONSTITUTION: When the digital video signal (270Mbps) of a 525/60 system D1 type is converted into the data format of an ATM line signal and transmitted through two lines, the number of cells of signal components (signals in a horizontal and a vertical blanking period) in a data area other than an active area is 2,860. The number of cells assigned to each line in the AAL5 layer is 11,778. The number of cells assigned to a video signal area is 8,909 in consideration of various control signals. A video signal component in each frame on one ATM line has 9,740 cells, so the cell ratio of the both is 8,909/9,740=0.915. In this case, when a video signal is compressed to >=91.5% for each ATM line, the video signal can be accommodated in the remaining ALL5 layer. The video signal is highly correlated, so data compression to this extent does not spoil the picture quality.

Abstract: PURPOSE:To reduce noise caused by discontinuous points by recording digital video data and digital audio data on tilted tracks of a magnetic tape and reading the data by deshuffling against the audio data of field sequence. CONSTITUTION:Audio signals with a format, in which effective sampling numbers in a field are, for example, 800 and 801 samples and the total of effective sample numbers of five continuous fields is 4,004 samples, are recorded on a magnetic tape. When the audio signals are to be reproduced, the following is done, i.e., the recording device is provided with an edge detector 56, a shifter 61 which forms a signal indicating an end of five fields, a counter 60 which counts a total of effective sample numbers of five fields and a plug generator 62 which raises a mute plug DE2XJP corresponding to a last sample of the five fields when a total of effective sample numbers exceeds 4,004 samples.

Abstract: PURPOSE:To prevent a burst flag signal from being generated in an erroneous timing by detecting the width of a synchronizing pulse separated from a video signal and returning the level of a charge discharge circuit to an original level when the detected pulse width is narrower than a prescribed value. CONSTITUTION:When a pulse width detection circuit 21 detects it that the width of a synchronizing pulse included in a composite synchronizing signal fed to a terminal 1 is a prescribed width t2 or over, a detection pulse going to a high level signal '1' is outputted and fed to an S input of an RS flip-flop 22 and its Q' output is fed to one input of an AND gate 25. Moreover, when an edge detection circuit 23 detects the trailing of the composite synchronizing signal fed to the terminal 1, a detection pulse is outputted and fed to the other input of the AND gate 25 via an inverter gate 24. An AND output of the gate 25 is fed to the S input of the RS flip-flop 26 and its Q output is fed to a rapid charge circuit 27. The rapid charge circuit 27 restores the capacitor 12 to a prescribed level V1 in a short period of time when a high level signal '1' is fed from the flip-flop 26.

Abstract: PROBLEM TO BE SOLVED: To protect the protection information appropriately in an environment where the protection information is delivered/received by a plurality of apparatus. SOLUTION: A security manager 21 manages key data to be used as a common key in a security group 51, i.e. LE Key 61, D Key 62 and N Key 63. On the other hand, the security manager 21 manages subscription to the security group 51 for each apparatus connected thereto until now, and sets the key data managed by itself as the common key for apparatus subscribed to the security group 51, e.g. the information processors 1-5 on Fig. 1, and manages the set content. The invention is applicable to a system in which a security group is formed. COPYRIGHT: (C)2008,JPO&INPIT
