发明名称 VIDEO DATA REPRODUCER OF A VIDEO COMPACT DISC PLAYER
摘要 The present invention is directed to a method and apparatus for outputting video data of a video compact disc player. A video signal of lines 1 to 425 recorded in a PAL system is outputted as a picture signal under the control of the control section, and the caption detecting section detects and counts a horizontal synchronizing signal included in a video signal corresponding to a region of 200 lines ranging between lines 426 and 625 recorded in the PAL system to detect an edge component. Further, the data mapping section compresses by half the video signal corresponding to the detected region of 200 lines and provides a compressed video signal as caption data. Therefore, when a video signal recorded thereon in the PAL system is displayed via a display equipment of an NTSC system, the picture signal is displayed on a screen which ranges between lines 1 and 425, and the caption signal is displayed on a screen which ranges between lines 426 and 525. Consequently, the video signal is displayed without a loss of caption data.
