Digital selective calling (DSC) is a standard for transmitting predefined digital messages via the medium-frequency (MF), high-frequency (HF) and very-high-frequency (VHF) maritime radio systems. It is a core part of the Global Maritime Distress Safety System (GMDSS).
A digital signal controller (DSC) is a hybrid of microcontrollers and digital signal processors (DSPs). Like microcontrollers, DSCs have fast interrupt responses, offer control-oriented peripherals like PWMs and watchdog timers, and are usually programmed using the C programming language, although they can be programmed using the device's native assembly language.
XML Signature (also called XMLDSig, XML-DSig, XML-Sig) defines an XML syntax for digital signatures and is defined in the W3C recommendation XML Signature Syntax and Processing.
While XML-DSig is a general framework for digitally signing documents, XAdES specifies precise profiles of XML-DSig making it compliant with the European eIDAS regulation (Regulation on electronic identification and trust services for electronic transactions in the internal market).
The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem.
The public key used to authenticate the code signature should be traceable back to a trusted root authority CA, preferably using a secure public key infrastructure (PKI). ). This does not ensure that the code itself can be trusted, only that it comes from the stated source (or more explicitly, from a particular private key
DSC version 1.0 was released on 10 March 2014, but was soon deprecated by DSC version 1.1 released on 1 August 2014. The DSC standard supports up to a 3∶1 compression ratio (reducing the data stream to 8 bits per pixel) with constant or variable bit rate, RGB or Y′C B C R 4:4:4 , 4:2:2, or 4:2:0 color format, and color depth of 6, 8, 10, or ...
Inno Setup grew popular due to being free for both commercial and non-commercial use, [4] many software companies switched to the tool. [citation needed] Since Inno Setup was based around scripting, fans of Inno Setup started ISTool and ScriptMaker to aid in visual and simpler ways to make installations for Inno Setup.
