    • The present invention discloses a multi-carrier digital multimedia broadcast system and the digital information transmission method thereof. After RS encoding and byte interleaving, LDPC encoding, bit interleaving and constellation mapping to an upper layer of data streams in turn, the obtained data symbol is multiplexed with scattered pilots and continual pilots which include the system information to form an OFDM frequency domain symbol and scrambled; an OFDM time domain symbol is generated by IFFT transforming, and after inserted with the frame head to build a time slot, it is connected to form a signal frame of the physical layer; the signal frame of the physical layer is transmitted after being low-pass filtered and orthogonal upconverted. The system and method thereof provide wireless broadcast with high quality such as audio, video and multimedia data and the like for mobile, fixed and portable receivers, and can use the satellite transmission and terrestrial transmission method for transmitting. The method utilizes the LDPC OFDM scheme, and the system applies the microwave and large scale integrated circuit technologies while fulfills the needs for low cast and high performance.

    • The present invention provides a customizing system and a customizing method for converting a desktop application into a web application. A required processing logic may be added by locating an interface element which is needed to be modified, and modifying a callback function of the interface element (interface description data), so as to implement user's operations on local data by a web application. When a user operates on the modified interface element at a browser side, the added processing logic automatically converts the user's operation to a plurality of operations, so that the user may feel that he is operating on a local file at the browser side, rather than a remote file at a server side. The present invention may implement complex webpage function customization, and thus may implement remote operations on local data.
    • 本发明提供了一种用于将桌面应用转换成web应用的定制系统和定制方法。 可以通过定位需要修改的接口元素和修改接口元素的回调函数(接口描述数据)来添加所需的处理逻辑,以便通过web应用来实现用户对本地数据的操作。 当用户在浏览器侧对修改的界面元素进行操作时,所添加的处理逻辑自动将用户的操作转换为多个操作,使得用户可以感觉到他在浏览器侧在本地文件上操作,而不是 服务器端的远程文件。 本发明可以实现复杂的网页功能定制,从而可以对本地数据实现远程操作。
