to the analog caption decoder 506 if the received caption data is analog caption data user_data outputted from the video parser 505 is not processed by the digital caption decoder 507 the analog caption decoder 506 finds out s 18 analog caption data made in the scte 20 or the dvs 157 standard from user_data inputted from the video parser 505 on the basis of the vbi line information and the line field information and decodes the analog caption data s 19 the analog caption data found by the analog caption decoder 506 is transmitted to the video combiner 509 the video combiner 509 combines the analog caption data video data outputted from the mpeg 2 video decoder 508 and signals outputted from the graphic block 510 signals outputted from the video combiner 509 are transmitted to the video reconstructor 511 the video reconstructor 511 reconstructs a caption by encoding analog caption data outputted from the analog caption decoder 506 at a vbi 21 st line the reconstruction of a caption is to prevent analog caption data from being an open caption in case of storing data as it is outputted from the video combiner 509 in a storage medium such as a vcr video cassette recorder if the received caption data is analog caption data under the eia 708 standard if analog_cc_type 1 the controller 504 transmits line_field information included in the caption information to the analog caption decoder 506 since analog caption data.
