Abstract: A display driver circuit, configured to drive a display panel, includes a time recording circuit, a storage circuit, and an output control circuit. The time recording circuit calculates a first time interval between a first vertical synchronous pulse and a second vertical synchronous pulse subsequent to the first vertical synchronous pulse. The storage circuit stores a display data corresponding to the first vertical synchronous pulse when the first vertical synchronous pulse is received by the display driver circuit. The output control circuit is coupled with the time recording circuit and the storage circuit. When the display driver circuit receives the second vertical synchronous pulse, the output control circuit outputs data pieces, generated by dividing the display data, to the display panel. The data pieces are outputted at second time intervals, and each of the second time intervals is positively correlated with the first time interval.

Abstract: The disclosure proposes a method and a system for 360-degree video playback. The method is applicable to a video playback system and includes at least the following steps. A current frame of a 360-degree video having a sequence of frames is received. Candidate objects in the current frame are detected, and a main object is selected from the candidate objects by using a selector recurrent neural network (RNN) model based on information of the candidate objects in the current frame. A viewing angle corresponding to the current frame is computed by using a regressor RNN model based on the main object in the current frame. The current frame is displayed on the screen according to the viewing angle.
