<p><P>PROBLEM TO BE SOLVED: To provide a digital information transmission/reception method whereby a sender side eliminates the need for an MPEG moving picture for reverse reproduction or the like purposely and a receiver side can smoothly reverse- reproduce an MPEG moving picture or the like for a streaming service. <P>SOLUTION: A transmitter side of video information divides the MPEG moving picture into a plurality of blocks (B1 to B5) and transmits the blocks to a receiver side from the temporally-later block (B5). When the receiver side receives the blocks B, the receiver side extracts a temporally-later GOP in the blocks B, converts each video image into I pictures (I<SB>1</SB>I<SB>2</SB>I<SB>3</SB>I<SB>4</SB>I<SB>5</SB>I<SB>6</SB>I<SB>7</SB>) applies reverse sequence rearrangement processing to the I picture video image (I<SB>7</SB>I<SB>6</SB>I<SB>5</SB>I<SB>4</SB>I<SB>3</SB>I<SB>2</SB>I<SB>1</SB>) and displays the video images. Then the processing above is executed for the GOP in the order of the GOP arranged in a temporally-reverse order in the blocks, and performs the reverse sequential processing, applied to the one block, sequentially to the succeeding blocks. <P>COPYRIGHT: (C)2003,JPO</p> |
