Abstract
A method for rendering video frames by a computing device having a software stack with an application layer and a kernel layer comprises various steps. First, a system reference time is initialized. A triggering of an interrupt signal in the kernel layer is waited for. Next, it is determined whether to update the system reference time as a function of a render function from the application layer. A next video frame in the kernel layer is rendered by the computing device as a function of the determined system reference time and the next video frame. The steps after the initializing step and starting at the waiting step are recursively performed.
