<p>In a system wherein video data (93) and audio data (98) are reproduced in a non-presentation mode of sub-picture data (95), control information having an effect process command is transferred to a system CPU before the video data (93) is transferred to a decoder section. After the reproduction of the video data (93) and the audio data (98) selected in association with the video data (93), e.g. English audio data (98), is started, sub-picture data (95), e.g. an English caption, is forcibly presented at a predetermined timing under the effect process command. After a predetermined time period, the presentation of the sub-picture data (95) is disabled by the effect process command. <IMAGE></p> |
