隨著硬體設備不斷推陳出新,以及網際網路的快速發展,現在的使用者漸漸地改變了對於電子產品的選擇取向,愈來愈多的行動裝置出現在我們的身邊,而攜帶性較低的個人電腦或是筆記型電腦,雖然仍然在我們的生活中扮演重要的角色,但使用的頻率已經漸漸地被行動裝置瓜分。對大眾來說,能夠應對不同狀況,而切換不同需求的多平台生活型態是更加方便的,在定點時能夠使用效能強大的個人電腦,拜訪客戶時可以使用平板進行展示,休閒時能使用手機觀看影片,驅使大家同時擁有不同平台的裝置。同時隨著資訊傳遞的能力提升,也漸漸有很多影片模式的創作開始出現,並愈來愈熱門,當這些影片創作愈來愈多的時候,有些創作就會開始以營利為目地的,但影片類的產品如果沒有保護,是非常容易複製的。為了保護這些創作,我們希望打造一個能夠保護創作者權利的系統,並且盡可能的不讓使用者對我們的系統感到排斥。因此,我們打造一個具有解密功能的播放器,不僅如此,我們也實現了跨平台的功能,能夠讓開發者有更簡潔的開發,而消費者可以不受到平台的限制,在任意的平台上觀看影片。;With the hardware industry progress and the development of internet networks. People are changing their use intention of electronic devices. More and more mobile devices appear around us. Although the low portability device like desktop or laptop are getting less opportunity to been used, but they still play an important role in our life. For most of people, having different platform devices at the same time is more convenience, when you not moving you can choose powerful desktop, and when you go to visit the client that you can choose tablet for display you report, and watch video for your free time. Those different demand made people have different platform devices. At the same time, the capability of data transmission progress, there are more and more video product appear, and getting more popular. When those video works amount increase, there are some video works starting getting profit. However, if the video product without protection is easily to be misappropriation and duplication. For that issue, we want to create a system that could protect creators’ rights, and reduce the customer’s loathing as possible as we can. So that we implement a media player supports DRM system, more than that we combine cross-platform ability. For the creators, they have simple way to develop; for the customers, they could play the video on any platform device without restrict of platform.
