The present invention relates to a data processing apparatus, a data processing method, a program, a program recording medium, a data recording medium, and a data structure that enable reading of coded video data in access units without analyzing the coded video data. In step S, a private_streampacket is searched for, which is used for decoding coded video data, and which is located immediately prior to each of one or more decode startable points in coded video data in the access units. In addition, in step S, based on an AU_length which is included in the private_streampacket, and which represents the size of each of access units located from the private_streampacket to the next private_streampacket, the coded video data is read in the access units. The present invention can be applied to, for example, game machine using DVDs, etc.

Data processing device, data processing method, program, program recording medium, data recording medium, and data structure

An image processing apparatus capable of preventing a copy protect function of a video or other contents signal from being disabled. An encoder encodes a contents signal from a DVD reproduction unit. A copy protect circuit performs copy protect processing on the encoded signal and outputs it. The copy protect circuit is controlled by control data input from CPU via an I2C_IF circuit. At this time, verification data from the CPU is stored in, and then read from registers in the I2C_IF circuit. Then, the CPU verifies the destination of transmission of the control data.

A security system for preventing disc players from being used with unauthorized software is disclosed. The security code is stored through modulating an offset of the physical position of a plurality of data bits from a nominal track position. A two part optical read head provides an RF signal corresponding to the presence of a physical offset modulation. The RF signal is present when there is a physical offset of the data bits defining a first logical state and the absence of the RF signal defines a second logical state. A digital security code is encoded and decoded in this manner. A system for encoding a security code through modulating the physical offset of a plurality of data bits from a nominal track position is also disclosed.

A PCM signal editing apparatus with functions of storing in memories the edit-point proximate sample data of a first PCM audio signal reproduced from a first recording medium and that of a second PCM audio signal reproduced from a second recording medium, then reading out such sample data of the PCM audio signals at a desired speed from the memories respectively in a manner to attain a coincidence of the edit points, and cross-fading the signals at the edit-in point or edit-out point in a cross-fade time conforming with the read-out speed, thereby performing a short-time insert editing operation with high efficiency and sufficient certainty. Furthermore, the apparatus is so contrived that the editing conditions proximate to the edit points of the PCM audio signals can be aurally perceived with accuracy, and the access states of the memories are displayed by bar graphs to consequently render the editing state visually recognizable.

According to the present invention, a fish growth hormone was isolated from an organ culture broth of the pituitary gland of eels, and further a recombinant DNA incorporated with a DNA coding for the eel growth hormone polypeptide and a microorganism containing the recombinant DNA were obtained. They can be used for mass production of an eel growth hormone.
