Patent

CA 2173923

In a system wherein video data and audio data are reproduced in a non-presentation mode of sub-picture data, control information having an effect process command is transferred to a system CPU before the video data is transferred to a decoder section. After the reproduction of the video data and the audio data selected in association with the video data, e.g. English audio data, is started, sub-picture data, 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 is disabled by the effect process command.
