Description
    FIELD OF THE INVENTION
  • [0001]
    The present invention relates to an entertainment system and a portable display apparatus thereof, and more particular to a wireless entertainment system and a portable display apparatus thereof.
  • BACKGROUND OF THE INVENTION
  • [0002]
    The used display apparatus of an entertainment system currently is usually immobilized thereon by screwing and thus, it is not easy to separate/detach the display apparatus and the entertainment system therefrom. For example, the conventional liquid crystal display (LCD) apparatus on a headrest of a vehicle is not easy to be separated from the headrest, since it is usually fixed to the headrest in the vehicle. Besides, the immobilized liquid crystal display (LCD) apparatus always risk being stolen since it is left in the vehicle without anybody therein. In addition, since it is not easy to separate the immobilized liquid crystal display (LCD) apparatus from the headrest, the mechanical design of the conventional immobilized liquid crystal display (LCD) apparatus also suffers the inconvenience problems while being repaired or maintained. Furthermore, for a long-term consideration, if the liquid crystal display (LCD) apparatus is not easily detachable or is not portable (since it can't be separated from the headrest), it is inconvenient to upgrade the vehicle liquid crystal display (LCD) apparatus in compliance with the application requirements.
  • [0003]
    Furthermore, since the immobilized display apparatus is fixed to either a specified position or a specified object, it is not considered as a multiple usage device. For example, on one hand the immobilized display apparatus is unable to be incorporated desirably with other devices, such as a desktop computer or an expandable device, and on the other the immobilized display apparatus is unable to be carried everywhere desirably and easily. Take the prevailing entertainment system and the display apparatus thereof of a motorcar as an instance, except for having the above-mentioned defects regarding safety, repair, maintenance and upgrade for the system, and having the inconveniences derived from its un-portability, this kind of entertainment system and the display apparatus thereof also lack the following essential benefits.
  • [0004]
    With the improvement of living standard and the changes of lifestyle, it is no longer to restrict the entertainment system to an indoor restricted system. The prevailing point of view is to apply the entertainment system in multiple ways and at various places. The motorcar with an entertainment system is a dominant example, and this kind of motorcar is no longer being considered for transportation only. Actually the motorcar with an entertainment system is a multiple function vehicle. For satisfying the above-mentioned desire, the present vehicles are equipped with various media devices. Hence, an entertainment system being suitable for both indoors and outdoors are desired.
  • [0005]
    At present, the video-NTSC/PAL signal is wire transmitted to the liquid crystal display (LCD) apparatus by the operation of a media center system having a video compact disc (VCD) player or a digital video disc (DVD) player equipped for the vehicles so as to play the media data on one or more liquid crystal displays. Since the immobilized display apparatus uses lots of wiring for communicating with the player, it is not simple and easy to be repaired or set up.
  • [0006]
    The mentioned wired entertainment system further has the other drawbacks. Although the wired entertainment system may have a plurality of liquid crystal display (LCD) apparatus respectively for several users, all of the liquid crystal display (LCD) apparatus still plays the same media data at the same time. That means all of the liquid crystal display (LCD) apparatus works synchronously while the wired entertainment system executes comments, such as forward, backward, paragraph selection, pause, play, stop etc. . . . Hence, at the same time, the wired entertainment system is controlled by only one of the users and the rest just only passively watch the program.
  • [0007]
    The wired connection between each device of the present entertainment system make the entertainment system lack capability of diversifying the application of each device therein and combing each device therein with the other apparatus, especially in the case of the immobilized display apparatus of the entertainment system. As mentioned above, if it is not easy to remove the display apparatus from the entertainment system or the display apparatus is not portable to other places, it would be not easy to upgrade the entertainment system and the display apparatus, or to be integrated with other devices or techniques, such as a wireless local area network (WLAN) or a media player. According, under the scheme of the conventional entertainment system, the user could not arbitrarily control the media data playing, such as a song or a movie even though the user has his own personal display apparatus. In addition, the user could not enjoy the media data by the display apparatus of the conventional entertainment system at any places one's like. Moreover, one could not use the immobilized display apparatus by combining it with the other expandable apparatuses for the purpose of high-potency usage.
  • [0008]
    In view of aforesaid discussion, to provide an entertainment system for diverse applications and a portable display apparatus for portable usage is an industrial subject at present. In addition, for consideration of the prevalence of display apparatus of an entertainment system for applying in various places such as a moving vehicle, a suitable portable display apparatus for moving vehicles is also desired. Therefore, an entertainment system and a portable display apparatus thereof considering the safety, the simplified maintenance and upgrade, and the detachability and portability are provided in the present invention.
