Frame synchronizing device and method therefor

摘要

A frame synchronizing device for synchronizing systems having a digital interface (210) and a method therefor are provided. The systems are synchronized by extracting frame time information from a signal transferred from an external source through a digital interface, generating a frame reset signal (FRP) delayed by predetermined time on the basis of the extracted frame time information, and resetting the entire systems according to the generated frame reset signal. Also, the colour burst signal is free-oscillated during the digital interface mode, in order to accommodate to the frame reset signal which has a variable period. <IMAGE>
