Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
In semiconductor devices, parasitic structures, irrelevant for normal operation, become important in the context of failures; they can be both a source and protection against failure. Applications such as aerospace systems, life support systems, telecommunications, railway signals, and computers use great numbers of individual electronic ...
In digital devices, changes to the analog video signal are created by a chip that converts the digital video to analog within the device. In DVD players, trigger bits are created during DVD authoring to inform the APS that it should be applied to DVD players' analog outputs or analog video outputs on a PC while playing back a protected DVD ...
K-nearest-neighbors algorithm (kNN) is one of the oldest techniques which has been used to solve fault detection and diagnosis problems. [14] Despite the simple logic that this instance-based algorithm has, there are some problems with large dimensionality and processing time when it is used on large datasets . [ 15 ]
The Video Content Protection System (VCPS) is a standard for digital rights management, intended to enforce protection or DVD+R/+RW content and related media. It was designed to protect video recordings broadcast terrestrially with the broadcast flag used for digital high-definition programming, but its use has been expanded to cover programming obtained in other ways, such as via cable and ...
The original secure cryptoprocessor was designed for copy protection of personal computer software (see US Patent 4,168,396, Sept 18, 1979) [5] to provide more security than dongles could then provide. See also bus encryption. Hardware cloning, where the dongle is emulated by a device driver, is also a threat to traditional dongles.
A general protection fault (GPF) in the x86 instruction set architectures (ISAs) is a fault (a type of interrupt) initiated by ISA-defined protection mechanisms in response to an access violation caused by some running code, either in the kernel or a user program.
