Buffer control device and receiving apparatus

Abstract

A buffer control device is provided with a nearly flow detecting section, a vertical cycle control section and a vertical synchronization signal generating section. The nearly flow detecting section compares the amount of data accumulated in a buffer and predetermined thresholds and detects the result of the comparison as nearly overflow or nearly underflow. The vertical cycle control section adjusts the length of a vertical synchronization cycle according to the result of the comparison by the nearly flow detecting section. The vertical synchronization signal generating section generates a new vertical synchronization signal from the result of the adjustment by the vertical cycle control section.
