AV-PCL Time Code reader cards for the PCI express bus are an important computer hardware solution for software development in fields such as subtitling, computer controlled editing, interactive video, technical scientific analysis, and other applications that are based on picture accurate video processing.
Driver compatibility between analog, digital and HD "high definition" cards, enables you to design a software with any one of these cards and then if future requirements need a different video source, just change to a compatible Alpermann+Velte PCIe card. The 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. Cards have an automatic frame rate detection (24, 25, 30, 30 DF). The parallel operation of two or more PCL PCIe-Cards is supported. Drivers and example programs for NT 4.0/2000/XP/Vista and Linux are included. DLL functions for reading Time Code and configuration are given. C/C++, Visual Basic and Delphi are also supported.
PCL-PCIe TS was designed for the synchronization of a Windows NT/2000/XP or Vista system clock with a realtime locked LTC Time Code signal. The included Windows program "TimeSys" completely controls this realtime process.
