This typically further includes displaying a Main Menu that represents these files and playing Main Menu items as regular video files/contents. While the content selection file is played back, a content selection menu is generated by the storage device and displayed by the host, and each content selection menu item is playable by transmitting a playback command to the storage device rather than to the host. A storage device is also provided, which uses such method. ## Claims ### Claim 1 A storage device for providing a video stream to a host, the storage device comprising: a first memory for storing content, the content including video files;
