DTV linux device abstraction for embeded systems

This paper presents an approach to create Linux Device Driver Framework which will be used for representation and control of DTV related HW components found in Set-top boxes (STB) and TV sets (iDTV). During previous years LinuxTV was established as promising architecture for PC TV cards, but from the announcement of Linux DVB API v3 there was no progress toward embedded systems. Therefore, attempt is made to improve and replace existing Linux DVB paradigm, and to introduce concepts applicable and optimized for embedded systems. Layered SW architecture is developed, which simplifies Kernel Drivers development, and export well defined APIs to user space applications.
