AV PCL Time Code reader cards for the PCIe express bus are an important computer hardware solution for software development in fields such as subtitling, computer controlled editing, interactivevideo, technical scientific analysis, and other applications that are based on picture accurate video processing. Driver compatibility between analog, digital and HD video cards enables you to design a software which is interoperable with any Alpermann+Velte PCI or PCIe card. Each card has its own processor system with a register set for data transfer. Thus the critical time routines are completely decoupled from the PC's CPU, which enables extensive error checking. An automatic frame rate detection (24, 25, 30, 30 DF) is supported as well as the parallel operation of two or more PCL PCIe-Cards. Drivers and examplary programs for Windows XP/Vista/7/8/ 2003/2008 32- and 64 bit and Linux are included. DLL functions for reading Time Code and configuration are given. C/C++, Visual Basic and Delphi are also supported.
