PURPOSE: A method and a device for transmitting video data to a terminal are provided to display the high resolution video data on a two-level black and white monitor by encoding the video data in various resolutions. CONSTITUTION: A video data transmission method comprises the steps of obtaining high resolution bit streams by encoding high resolution video data to transmit(41), converting the high resolution video data into low resolution video data(42), obtaining low resolution bit streams by encoding the converted low resolution video data(43), and transmitting the high resolution bit streams and low resolution bit streams to a receiver terminal(44). Since high resolution video data are transmitted to a low resolution terminal after being converted into low resolution video data, video data are transmitted to terminals of various resolutions.
