Title: Multimedia player receivable satellite signals

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to a multimedia player, and particularly to a multimedia player receivable satellite signals.  
      2. Prior Art  
      A television (TV) set is used to receive program signals and play program. In accordance with transmission manner of program signals, the TV is classified to three types, that&#39;s traditional radio-vision, cable TV and satellite TV. As it is well known, as to the traditional radio-vision, program signals can be received only within a narrow scope, and program&#39;s available choices are limited. Though the cable TV can receive quite a lot of programs, it is complicated to construct transmitting cable. The satellite TV can overcome the above shortcomings of the traditional radio-vision and the cable TV. Furthermore, the satellite TV can transmit audio and video (AV) signals with higher quality form.  
      A storage media which is a compact disc (CD) provides a new selection of watching and hearing with higher quality and larger capacity. Currently, the storage media may be also a CD/R, a VCD, a DVD, or a DVD/R.  
      Oftentimes, a satellite TV and a multimedia player are arranged together to have their functions.  FIG. 1  shows conventional multimedia configuration  2 . When an audience  1  wants to watch satellite TV, a satellite antenna  21  and a top box  22  are required with the top box  22  being connected to a display  24  for video output and a megaphone  25  for audio output. When the audience  1  wants to play CD, a CD player  23  is connected to the display  24  and the megaphone  25  and then turned on. Similarly, when the audience  1  wants to use other format multimedia device  3 , the other format multimedia device  3  is connected to the display  24  and the megaphone  25 . Therefore, the conventional multimedia configuration  2  occupies large space and is not portable. Furthermore, it is complicated to connect the above components or modules and so it is not convenient in use.  
      Additionally, the multimedia configuration  2  need an external power supply device  4  to supply power. The external power supply device  4  may be a home electrical socket, a mini-type dynamo, or a vehicle battery. Since the components or modules of the multimedia configuration  2  are separated, many power wires are required to connect to the external power supply device  4 , which results in inconvenience in use.  
     SUMMARY OF THE INVENTION  
      Accordingly, an object of the present invention is to provide a multimedia player receivable satellite signals which has functions of a satellite TV and a CD player.  
      Another object of the present invention is to provide a multimedia player receivable satellite signals which is portable and convenient in use.  
      Another object of the present invention is to provide a multimedia player receivable satellite signals which has a plurality of I/O ports for expanding functions thereof.  
      To achieve the above-mentioned objects, a multimedia player receivable satellite signals in accordance with the present invention includes a CPU, an improved satellite antenna connected to the CPU for receiving the satellite signals, a CD-ROM connected to the CPU for reading a CD received therein, an operation interface connected to the CPU, an LCD connected to the CPU for video output, a speaker connected to the CPU for audio output, and a battery pack connected to the CPU as a power supplier.  
      Other objects, advantages and novel features of the present invention will be drawn from the following detailed embodiment of the present invention with attached drawings, in which:

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
      A multimedia player receivable satellite signals of the present invention is combined with a CD multimedia player and an antenna for receiving satellite TV signals and is configured to be portable and convenient in use.  
      Referring to  FIG. 2 , the multimedia player  5  receivable satellite signals of the present invention employs a CPU  51  to control other components or modules thereof. An improved satellite antenna  52  and a CD-ROM  53  are employed as audio and video (AV) input devices. The improved satellite antenna  52  is flat and foldable. An LCD  54  is employed as a video output device instead of a traditional display and connected to the improved satellite antenna  52 . When the LCD  54  is not in use, the LCD  54  can be folded to a closed position thereby protecting the display panel and reducing occupying space. A speaker  55  is employed as an audio output device instead of a traditional megaphone and disposed near the LCD  54  for saving space. As shown in  FIG. 3 , an audience  1  may input a command through an operation interface  56  for selecting one of programs or one of functions of the multimedia player  5 . The operation interface  56  can convert and transmit the command signal to the CPU  51  which controls operation of corresponding components or modules in accordance with the command signal.  
      As shown in  FIG. 3 , the CPU  51  has a function of a conventional top box which is capable to code and encode satellite signals. The improved satellite antenna  52  receives satellite signals and then transmits the satellite signals to CPU  51  for processing just as a traditional satellite antenna plus a top box which used in a satellite TV. Thus, the multimedia player  5  of the present invention does not need the conventional top box  22 , which results in reducing cost and saving occupying space thereof. Similarly, the multimedia player  5  of the present invention replaces a conventional CD player  23  with a CD-ROM  53  connected to the CPU  51 . Therefore, multimedia signals with different formats may be input to the CPU  51  for processing and then outputting multimedia signals with same format. Thus, the multimedia player  5  of the present invention has functions of a satellite TV and a CD player.  
      As shown in  FIG. 2 , an external battery pack  58  is connected to the multimedia player  5  as a power supplier to the multimedia player  5 . The battery pack  58  is replaceable and so the multimedia player  5  can be supplied with continuous power through replacing the battery pack  58  when used up. Thus, the multimedia player  5  can work without an external power supply device  4  through the battery pack  58 . Furthermore, referring to  FIG. 2 , a power pack  59  is provided to connect between the battery pack  58  and the external power supply device  4  for charging the battery pack  58 . Of cause, the power pack  59  can connect to and supply power to the multimedia player  5  directly. The external power supply device  4  may be a home electrical socket, a mini-type dynamo, or a vehicle battery.  
      As described above, the signal input device such as the improved satellite antenna  52  and the CD-ROM  53 , the signal output device such as the LCD  54  and the speaker  55 , and the body of the multimedia player  5  such as the CPU  51 , the operation interface  56  and the battery pack  58 , are miniaturized and lighten thereby reducing volume and weight of the multimedia player  5  of the present invention. Thus, the multimedia player  5  of the present invention is convenience and portable.  
      Referring to  FIG. 3 , the multimedia player  5  of the present invention includes a plurality of I/O ports  57  at one side thereof for connecting to other format multimedia devices  3  thereby expanding functions of the multimedia player  5 . As mentioned above, the CPU  51  has functions of coding and encoding for different formats. Therefore, multimedia signals with different formats may be input to the CPU  51  for processing and then outputting multimedia signals with same format. Thus, the multimedia player  5  of the present invention has expanding functions.  
      It is understood that the invention may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
