摘要:
At least one kind of control signal concerning control of contents, added to specific locations inside contents data, is detected as first control information, and at the same time, at least one kind of control information concerning control of contents, embedded inside the contents data by a digital watermark, is detected as second control information. Consistency between the first control information as detected, and the second control information as detected is determined and on the basis of results of the determination, the control of the contents is executed. Thus, it is possible to reduce a possibility of the contents being improperly copied, thereby enabling the control with assurance of still higher safety.

A control system for executing an upshift from an off-going speed ratio to an on-coming speed ratio by controlling the release of the hydraulic pressure from the frictionally engaging element used for the off-going speed ratio and by controlling the supply of the hydraulic pressure to the frictionally engaging element used for the on-coming speed ratio comprises first and second off-going pressure releasing valves 70 and 80, which release the hydraulic pressure of the frictionally engaging element used for the off-going speed ratio, and a linear solenoid valve 60, which controls the operation of the off-going pressure releasing valves. The linear solenoid valve 60 controls the operation of the off-going pressure releasing valves in correspondence to the throttle opening of the engine. In this case, the smaller the throttle opening of the engine, the earlier the timing for releasing the hydraulic pressure from the frictionally engaging element used for the off-going speed ratio is set.

A time lapse magnetic recording/reproduction apparatus for recording and reproducing picture signals while intermittently thinning them out in a frame unit is used for monitoring and burglar-proofing in plants, shops, banks, etc. Recording picture information is generated and added to one continuous picture signal obtained by sequentially switching the output of each video camera, and is then recorded. A speed multiple k for a normal tape travelling speed is optimally set by servo circuit on the basis of the recording picture information (the total number m of channels) detected from the reproduction picture signals reconstructed by double-azimuth four heads at the time of search reproduction, and a search reproduction picture throughout the full screen of a monitor television is obtained in full recording channels. At the same time, a write period into an image memory is controlled in accordance with the recording picture information (the total number m of detection channels) and a reproduction head signal level, and read controller then controls sequentially readout of the picture signals from image memory storing therein only specific channels.
摘要:
An information recording and reproducing apparatus that prevents an information recording medium from being taken out of its cartridge inadvertently. The information recording medium allows recording information thereon by irradiation of an energy beam. The cartridge comprises a body and a cap adapted to a separable from the body or opened/closed thereon. An information recording medium is accommodated in the cartridge to allow recording and reproducing of information by irradiation of the energy beam. The cartridge also has locking member for fixing the body and the cap together in a closed state. If the information recording medium needs to be taken out of the cartridge after the same has been set on the recording and reproducing apparatus, the locking member is released to make the cap separable from the body or open on the body and the cartridge is ejected from the recording and reproducing apparatus.

A video printer comprises a main memory unit for storing data of a first picture, a sub-memory for storing data for an overlay region to be overlaid on the first picture and also indicative of a second picture to be displayed in the overlay region, a memory data processing unit for generating a synthesized picture by selectively controlling the picture data for the overlay region on the basis of the data stored in the sub-memory, a system control circuit for controlling the data storage in the main memory unit, the data storage in the sub-memory circuit and operation of the memory data processing circuit, and a print circuit for producing a hard copy on the basis of the output of the memory data processing circuit.
摘要:
As image processing method suitable for creative image generation in which the image data of an original image are divided into plural areas each consisting of plural pixels, the shape of these areas is modified according to the image data of the original image, and the pixel data in each area are processed in accordance with a representative value of the image data.
摘要:
A multivoice demodulator circuit in which a sub-signal is separated from the main signal. The sub-signal may have different content and characteristic dependent upon the reception mode of the original signal. The sub-signal is given different frequency characteristics dependent upon the reception mode.
摘要:
In a pulse width detector circuit, a high-level pulse width and a low-level pulse width of a digital signal derived by slicing an analog signal reproduced from a disc at a predetermined level are independently measured and maximum or minimum values thereof in a predetermined time interval are stored, and an average value, sum or difference of the maximum or minimum high-level pulse width and the maximum or minimum low-level pulse width is calculated to detect a correct pulse width of original data recorded on the disc.
