Abstract
The present invention relates to a video signal processing apparatus and video signal processing method, a video signal encoding apparatus and video signal encoding method, and a program which can solve an EPB problem involved when an encoded video signal is subjected to smart rendering editing. In an extraction process, if EPB problem occurrence prevention countermeasures have been taken in an H.264/AVC stream, smart rendering editing is performed without monitoring the occurrence of an EPB problem. If the countermeasures have not been taken, smart rendering editing is advanced while monitoring the occurrence of an EPB problem. And, in a case where an EPB problem of insertion of an EPB has occurred, a filler or a predetermined parameter corresponding to the inserted EPB is deleted. In a case where an EPB problem of deletion of an EPB has occurred, a filler corresponding to the deleted EPB is inserted. The present invention can be applied to a device that processes a video signal using the H.264/AVC scheme.
