A receiver for simultaneously displaying signals having different display formats and/or different frame rates, and a method thereof are provided. The receiver includes a signal generator, a first display processor, and a second display processor. The signal generator generates a first vertical synchronous signal for a high definition (HD) image, a first field identification signal for coping with a case in which an HD image is an interlace image, a second vertical synchronous signal for a standard image, and a second field identification signal for a standard image. The first display processor processes a received HD decoded image to an HD display format according to the first vertical synchronous signal and the first field identification signal. The second display processor down-samples the HD decoded image using the first and second vertical synchronous signals and the first and second field identification signals, and provides a standard definition (SD) image signal having a standard display format that is different from the HD display format. Accordingly, the receiver can simultaneously reproduce a high definition signal and a standard definition image signal corresponding to the picture quality of TVs which have already been commonly used, the two signals having different display formats and/or different frame rates. <IMAGE> |
