An apparatus, method and computer program product for transmitting a plurality of still pictures extracted from a picture stream. The apparatus (1) includes a transmission request receiving unit (11) for receiving a transmission request for the still pictures, and a transmission sequence determining unit (14) for determining a transmission sequence for the still pictures which is different than the sequence of the still pictures in the picture stream. Also included is a transmission unit (13) for transmitting the still pictures according to the determined transmission sequence. Further, a display apparatus, method and computer program product for displaying a plurality of still pictures extracted from a picture stream is also provided. The display apparatus includes a still picture receiving unit (44) for receiving a table having values corresponding to a sequence of the still pictures included in the picture stream, and for receiving any still pictures transmitted from an external apparatus. A still picture memory unit (42) is coupled to the receiving unit, and stores the table and any received still pictures. In addition, a still picture control unit (40) is coupled to the memory unit (42), and reads the table and determines whether or not a still picture corresponding to a value in the table is stored in the memory unit (42), and if the still picture is not stored in the memory unit (42), select another still picture that is saved in the memory unit and is closest in sequence to the still picture. A display unit (43) displays the still pictures selected by the control unit. <IMAGE> <IMAGE> |
