At the time of recovery from the error, based on the frame number of the retrieved intra-coded picture, elapsed time information to be displayed is updated, and error information indicating a period of frames dropped due to the occurrence of the error or the number of the frames dropped due to the occurrence of the error is displayed. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
