AUFZEICHNUNGS-/WIEDERGABEGERÄT FÜR VIDEO/AUDIO

摘要

A stream input unit (102) receives a transport stream. A subtitle information extracting unit (104) separates the received transport stream into subtitle information and information other than the subtitle information. Next, a stream format converting unit (105) converts separated video/audio information contained in the transport stream into a program stream of video/audio. A subtitle format converting unit (107) converts the subtitle information separated by the subtitle information extracting unit (104) into a program stream of subtitle information. Thereafter, a subtitle information inserting unit (108) inserts the subtitle information converted by the subtitle format converting unit (107) into the program stream converted by the stream format converting unit (105), and outputs the resultant program stream.
