Determines which surface is receiving the current field of video data for capture purposes.
Indicates that the driver manages the interrupt request.
Returns the polarity (even or odd) of the current field being written by the VPE object.
Determines which surface received the previous field of video data for capture purposes.
Determines which hardware bus master completed.
Locks the frame buffer so that it can be accessed.
