VIDEO/AUDIO RECORDING/REPRODUCING APPARATUS

摘要

A stream input unit (102) receives a transport stream. A caption information extraction unit (104) separates the received transport stream into caption information and information other than the caption. Subsequently, a stream format conversion unit (105) converts the video and audio information of the separated transport stream to the video and audio information of a program stream.In addition, a caption format conversion unit (107) converts the caption information separated by the caption information extraction unit (104) to the caption information of the program stream.A caption information insertion unit (108) then inserts the caption information converted by the caption format conversion unit (107) into the program stream converted by the stream format conversion unit (105) and outputs the result.
