    摘要: A digital conversion system for a color video signal comprising a system which selectively converts an analog composite color video signal and analog primary color video signals to digital signals includes: a matrix circuit (17) which forms a luminance signal and first and second color difference signals from the input analog primary color video signals; and a switching circuit (18) which converts the first and second color difference signals to a sequential color difference signal. A switch (28) selects the luminance signal from the matrix circuit (17) or the input NTSC analog composite color video signal. A first analog to digital converter (41) receives an output from the switch (28); and a second analog to digital converter (42) receives the sequential color difference signal. A digital composite color video signal or a digital luminance signal is obtained from the first analog to digital converter (41), and a digital line sequential color difference signal is obtained from the second analog to digital converter (42). The line sequential chrominance signal can be digitized by a single inexpensive A/D converter which has a slow processing speed, so as to produce an inexpensive digital conversion system which is small.

    摘要: In a net boot type thin client system, bottle necks concentrate on specific steps in a previously downloading method and an on-demand downloading method so as to hinder high-speed operation. Specifically, a previously file acquiring section for acquiring a file before the OS operates, an on-demand file acquiring section for acquiring a file while the OS operates, and a file determining section for determining whether or not a file is used in a high frequency. A high use-frequency file is downloaded before an OS operates and a low use-frequency file is downloaded while the OS operates.

    摘要: At the time of a maintenance work, a user computing machine does not give user data to a person (maintainer) who carries out maintenance and does not accept operations and data that are not relevant to the maintenance work so as to prevent the leakage of user data. Specifically, a user computing machine includes: a user data determination section determining whether a file of a VM of a computing machine used by a user is data created by the user, and a VM copy section, creating a copy of a VM which does not include data created by the user by calling the user data determination section. The maintenance is performed by supplying the VM which does not include data created by the user to a computing machine of the maintainer.
