     DETAILED DESCRIPTION 
       [0038]    The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment is this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
         [0039]    Take the download of a movie as an example, when the movie is downloaded from the network to a local memory unit, both the movie and a poster thereof are downloaded. Since the amount of data of the poster is far smaller than that of the movie, the poster is often downloaded at first. In the present disclosure, the downloading progress of the movie is displayed in the poster to allow users to obtain the downloading progress when watching the poster. 
         [0040]    Referring to  FIG. 1 , a television in an embodiment includes a micro control unit (MCU)  10 , a memory unit  11 , and an input/output (I/O) interface  12 . Under the control of the MCU  10 , the television downloads movies from the internet or a particular server via the I/O interface  12  in a wired or wireless way and further stores the movies in the memory unit  11 . 
         [0041]    Compared to a movie, a poster of the movie has much smaller amount of data and thus is downloaded at first. After the poster is downloaded, the MCU  10  is capable of processing the poster to be transparent or semi-transparent by any known technology. In the embodiment, the MCU  10  is capable of processing the poster to allow the poster to have a predetermined transparency. 
         [0042]    During download, the downloading progress is often expressed as a download ratio A which can be calculated as the following express A=M 1 /M, (wherein M 1  is the amount of data that has been downloaded, M is the total amount of data of the movie). The calculation of the download ratio A is executed by the MCU  10 . 
         [0043]    Referring to  FIG. 2 , after the poster is downloaded, the MCU  10  obtains a length L and a height H of the downloaded poster. During the downloading process of the movie, the poster and the downloading progress of the movie can be simultaneously obtained when users want to obtain the downloading process of the movie or want to watch the poster. The downloading progress is not displayed digitally, but shown in the background of the poster. For example, the poster is divided into a left portion S 1  and a right portion S 2 . The left portion S 1  displays the original poster, and the right portion S 2  displays the poster which has the predetermined transparency. The length L 1  of the left portion Si can be expressed by the following expression L 1 =L*A. Since A represents the downloading progress of the movie, therefore, users can estimate the downloading progress of the movie via the length L 1  of the left portion S 1  directly. As the downloading process goes on, the area of the right portion S 2  is adjusted to become smaller and smaller to show the change of the downloading progress of the movie in real time. In this state, the MCU  10  needs to calculate the length L 1  of the left portion S 1  periodically so that the area of the right portion S 2  can also be adjusted periodically. Thus, a time interval T, like 2 seconds, between two continuous calculations is set in the MCU  10 . The shorter the time interval T is, the better the display the will be. 
         [0044]    Referring to  FIG. 3 , a displaying method of displaying downloading progress of a file such as a movie is provided. The displaying method includes the following steps: 
         [0045]    step S 31 , downloading a poster of the movie and storing the poster; 
         [0046]    step S 32 , dividing the poster into a first portion S 1  corresponding to the original poster and a second portion S 2 , processing the second portion S 2  to allow the second portion S 2  to a have a predetermined transparency; 
         [0047]    step S 33 , calculating a download ratio A showing the downloading process of the movie; 
         [0048]    step S 34 , calculating a length L 1  of the first portion S 1  of the poster; 
         [0049]    step S 35 , adjusting area of the first portion S 1  according to the length L 1 ; 
         [0050]    step S 36 , determining whether the download ratio A is 100% or not, in other words, determining whether the movie has been downloaded completely or not, if the movie has been downloaded completely, the step S 34  is implemented again; otherwise, the step S 37  is implemented; 
         [0051]    step S 37 , the end. 
         [0052]    In the step S 34 , the length L 1  of the first portion S 1  of the poster is calculated periodically, and the time interval between two continuous calculations is two seconds in the embodiment. It is noted that the time interval between two continuous calculations is not limited to the embodiment. In other embodiments, the time interval may be set according to desires of users. 
         [0053]    Obviously, in the embodiment, the poster can be divided into an upper portion displays the original poster and a lower portion displays the poster which has the predetermined transparency. 
         [0054]    Additionally, the first portion S 1  and the second portion S 2  can be exchanged. That is, in the above embodiment, the second portion S 2  displays the poster has the predetermined transparency, and the first portion S 1  displays the original poster. 
         [0055]    Additionally, the way to process the poster is not limited to this embodiment. In other embodiments, a background color of the poster instead of the transparency of the poster can be changed according to the downloading progress, which is obvious to those of ordinary skill in the art. 
         [0056]    With the present disclosure, when the poster is processed, only the transparency or the background color of the poster is changed, and figures or scenes shown in the poster remain unchanged to allow users to watch the poster. Meanwhile, the downloading progress of the poster can be obtained by the poster. 
         [0057]    In a second embodiment, the color of at least one portion of a background of the poster can be replaced with a different color, or the transparency of the whole poster can be changed and a special color can be added to the background of the poster. In this state, the color replacing the background or the color added to the background of the poster change corresponding to the downloading process. For example, different kinds of color can be defined by the MCU  10  and then be stored in the television. Then, the background of the poster is processed to be transparent while the original picture of the poster is remained. After that, a red color is added to the transparent background of the poster. During the downloading process of the movie, as the downloaded amount of data of the movie increases, the red color gradually becomes lighter and the original background color of the poster is gradually re-shown. Specifically, a dark red color means that the downloaded amount of data of the movie is small, and a light red color means that the downloaded amount of data of the movie is large. 
         [0058]    From the above description, the displaying method of the present disclosure can be summarized as the following steps: downloading and storing the poster; processing the poster to allow the downloading progress of other information (such as the movie) to be displayed in the poster. The poster and the movie can be downloaded at the same time, or the poster can be downloaded in priority (that is, the poster is downloaded before the movie). The process of the poster can be adjustment of the transparency or the background color of the poster. The process of the poster can be adding of a color to the background color of the poster, and continuously change the added color, and so on. 
         [0059]    It is noted in some embodiments, the displaying method can also be applied to other video or audio files with a poster for introducing the content of the file such as an e-book with a cover as the poster. 
         [0060]    It is noted that in some embodiments, the displaying method can also be applied to a personal computer. 
         [0061]    Even though information and the advantages of the present embodiments have been set forth in the foregoing description, together with details of the mechanisms and functions of the present embodiments, the disclosure is illustrative only; and that changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extend indicated by the broad general meaning of the terms in which the appended claims are expressed.
