Method for establishing recording quality in digital recording device

The present invention relates to a method for establishing a recording quality in a digital recording device. In the present invention, still images associated with a plurality of recording qualities having different levels are displayed on a recording-quality selection menu image, and data streams are recorded at a recording quality selected through the recording-quality selection menu image. The still images are generated while a picture captured from video streams being differently encoded at the recording qualities. Otherwise, the still images are pre-stored in the digital recording device while being classified according to the recording qualities, and are read from the digital recording device. Also, the still images are displayed along with information associated with recording times for every recording quality. Therefore, a user easily compares video-data qualities in response to individual recording qualities with one another, and correctly selects a desired recording quality from among a plurality of recording qualities.
