There are provided a video player for outputting a video signal which enables a monitor to easily, reliably detect that a signal is in a letterbox format and a video system having the video player. When the aspect ratio of video data is 16: 9, the video player (1) converts the video data into an NTSC signal (100) in a letterbox format, outputting the thus-converted NTSC signal. In addition, the video player adds a closed caption signal to specific lines in a vertical blanking period, and each piece of 2-byte data is set to space. A 16: 9 aspect ratio monitor (40) receives an NTSC signal distributed by a distributor; detects that the closed caption signal is added to the NTSC signal and that data about the closed caption signal is space; and displays a main video in an zooming-in manner. A 4:3 aspect ratio monitor (42) displays the main video as is. |
