摘要： A video content generation device generates video data synchronized with music data based on motion data, representing a motion graph including nodes, edges, and weights, and metadata indicating a synchronization probability per each node between the motion graph and a musical tune. A music data storage unit stores the predetermined amount of music data and their musical characteristics in connection with the predetermined number of beats, in a reproduction order, retrieved from the musical tune. An optimum path search unit searches an optimum path connecting between nodes, each of which is selected per each beat with a high synchronization probability, on the motion graph with motion characteristics matching with musical characteristics based on the predetermined amount of music data. Video data synchronized with music data is generated based on synchronization information for correlating motion data to music data along with the optimum path.

摘要： A frame compensation method is provided. The method includes: obtaining a length of a lost frame and a length of a correct frame; determining that the length of the correct frame is integral power of 2 times of the length of the lost frame, and then obtaining a data sequence with the same length as the length of the lost frame according to the correct frame; and compensating the lost frame according to the data sequence to obtain a compensated data frame. A frame compensation system is also provided. Lost frames in various formats are compensated according to correct frames in various formats, so that the limitation of the related art that a lost frame in a single format can be merely compensated according to a correct frame in a single format is eliminated, and the effect of the compensated data frames is better than that of filling comfort noises.
