With technology's development, people are paying more and more attention on enhancing the quality of life. Multimedia devices hence come with the tide of fashion. With computer's popularity, broadband network users' and home network permeated rate increase, people through computers and networks carry out the data's transmission and communication. Because wireless broadband transmission can download with speed of 100 M bit/s, this transmission speed can proceed generally called image exchange. Its effect displayed on screen tableau can be 1024×768 pixels, so that multimedia audio-video content sharing can be achieved in home.
And currently a general family has various multimedia devices such as: television (TV), personal computer (PC), notebook (NB) and so on. Generally speaking, no matter it is a personal computer, notebook or television, in order to work normally, they need to have at least the following objects: a main frame, a screen and an external wiring. According to conventional knowledge, personal computer's display is separate from a main frame and has to be wired externally to make it work.
Due to wiring source site's and length's limitation, the screen has to be close to a main frame. Therefore, it causes a certain limitation on a screen's placement. Its distance is limited by wiring that causes the incapability to provide multimedia information with a longer distance transmission function. Although the notebook has a portable convenience, its screen and main frame are combined together and can not be separated. Therefore, it can only base on one-on-one to counter individual usage. It cannot provide general families the need of watching different programs. Further, traditional televisions are bulky and heavy, limited by wiring distance and needed to be connected with wires, and also not suitable to move. All these drawbacks added, furthermore, fails to conform to portable convenient need. From the foregoing, this invention is to improve the above-mentioned defects that have a lot of space for improvement and advancement.
The object of this invention is to let user's home portable display devices can proceed with wireless transmission through a main frame to solve a wired display device's defects that it is limited by a wiring distance and not separated from a main frame.
In order to achieve the object, this invention provides a multimedia system which at least includes: a main frame and at least a portable display device; a main frame is through wireless transmission of one to many separately to connect and correspond with display devices. A display device can apply and collocate with a main frame and both can be separately alone or integrate together. A main frame can be any computer platform. A display device is portable to enable users at any place in the home to enjoy multimedia programs through a peripheral control module or touch control panel to choose the favorite programs to watch.
The fundamental framework of a multimedia system of this invention at least includes a main frame and at least a portable display device to processing transmission and communication. A main frame and a portable display device are through wireless transmission of one to many to connect with each other separately. A main frame has not only functions of a general computer but also functions of digital television playing, web surfing, DVD playing, data storing, and radio listening and so on. Its portable display device has the characteristics of light and easy to carry. To move a display device has no need to move a main frame. The external wirings are all set on a main frame. A portable display has no need for any extra wiring then can through a main frame to process transmission and communication. There's no wiring distance limitation between the two and it's suitable for a general family application.
Therefore, this invention's multimedia system is applicable to solve the conventional defects. It can not only achieve fine vision and hearing effect but also can transmit a distance as far as about 30 meters by wireless transmission. The display device has no need to have any extra wiring. All the wirings are set on a main frame. This will conform to general families' need of convenience. Besides, when the portable display device is moved, it is no need to move the main frame. People can watch any program at any place in the house and further the portable device can combine with the main frame, so the invention can save space and money. The main frame does not have any limitation in space. Therefore, it will not cause any problem of design limitation due to heat radiation, convection and so on. The display device provides a multimedia display function and supports multiform multimedia digital data and has high compatibility. Further, the main frame has a one-to-many two-way wireless transmission function. Thus, it can correspond with the operation of a display device and further increases the capacity.
The following is through the preferred embodiment to illustrate an embodiment of this invention. One skilled in the art can through the proclaimed contents of this description easily understand this invention's other advantages and merits. It will be obvious that the same may be varied in many ways. Such variations are not be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of this invention. In order to let this invention's mentioned objects, features and advantages more obvious and easy to be understood, the following description provides a preferred embodiment and with correspondent illustrations of the attached describe more in details as follows.
To embody this invention's features and advantages, some of the typical preferred embodiment will be described in details at the latter part of this description. It's obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of this invention.
This invention is to combine wireless networking transmission technique with a portable display device together. A main frame is placed at a corner in a house and connects with outdoor ADSL or CABLE network. Through the main frame processes multimedia digital data to present video-sound effect on a portable display. Because the display has a portable convenience, it can be watched at any place in the house, so that it can satisfy general family's multiple and convenience requirements about multimedia digital video and audio.
Thus it is obvious, this invention takes advantage of separable and combinative of both a main frame and a portable display device, that really achieve the improvement of the conventional technique which has defects of incapable to move and not easy to carry. It is suitable for a family use and a main frame has no need to be light weight and compact, so there's no space design limitation problem due to heat radiation and so on. Its external wirings all are set on the main frame, so the display device has no need to have extra wirings.
A display device is portable. Through a main frame, it processes transmission and communication. There's no wiring distance limitation and is suitable for general families' need.
As mentioned above, this invention's wireless multimedia system can provide a one-to-many wireless transmission function and will not be limited by wiring distance that to proceeds with two-way transmission and communication to satisfy the need of a general family to watch different programs individually. And a hard disk drive can be a storage medium for multimedia digital data.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
