ABSTRACT:
A delay detector detects a reproduction delay for a video signal based on a delay notification communicated from a manager to manage the reproduction delay using a state variable. A controller conducts delay recovery control by forcing an image quality improving unit to omit filtering based on the state variable or switching the type of filtering to a simpler one, while avoiding the need to omit decoding of a frame (i.e., frame skipping). This results in a reduction in a load on a processor and recovery of the reproduction delay.
