  • Publication number: 20110273536
    Abstract: A picture transmission system is provided that provides a solution to drops in picture quality. A multiplexing unit (11) multiplexes N pictures in display order to generate a multiplexed picture. A transmission unit (12) transmits the multiplexed picture. A frame memory (23) delays pictures in the multiplexed picture that is received by a reception unit (21) by a one-frame interval of the pictures (one subframe interval) to generate reference pictures. With each reception of a picture in the multiplexed picture by the reception unit (21), an OD arithmetic unit (25) converts the picture element value of the picture (object picture) based on the reference picture to generate an OverDrive picture. A time-division display apparatus (3) displays the OverDrive pictures.
