    • A method applied in a display apparatus is provided. The display apparatus includes a first screen, a second screen, power signal means. The first screen is volatile. The second screen is non-volatile. The power signal means generate a power off signal in response to a user operation. The method includes: determining whether a power off signal is received; displaying a user interface on the first screen if the power off signal is received; controlling the display on the second screen in response to a user selection on the operation interface; generating a shutdown signal; and powering off the first screen, and the second screen when receiving the shutdown signal.
    • 提供了一种应用于显示装置的方法。 显示装置包括第一屏幕,第二屏幕,电源信号装置。 第一个屏幕是不稳定的。 第二个屏幕是非易失性的。 电源信号意味着响应于用户操作而产生断电信号。 该方法包括:确定是否接收到断电信号; 如果接收到断电信号,则在第一屏幕上显示用户界面; 响应于操作界面上的用户选择来控制第二屏幕上的显示; 产生关闭信号; 并关闭第一屏幕,第二屏幕接收到关闭信号。

    • A set-top box is provided. The set-top box includes a network interface, a wireless communication unit, and a processor. The set-top box connects to a network server through the network interface. The set-top box communicates with a portable device. The processor receives a play request signal including at least one keyword from the portable device through the wireless communication unit. Searches the network server to find at least one multimedia file through the network interface according to the at least one keyword included in the play request signal. Downloads the at least one multimedia file found from the network server, and transmits the downloaded portion of the at least one multimedia file to the portable device through the wireless communication unit.
    • 提供机顶盒。 机顶盒包括网络接口,无线通信单元和处理器。 机顶盒通过网络接口连接到网络服务器。 机顶盒与便携式设备通信。 处理器通过无线通信单元从便携式设备接收包括至少一个关键字的播放请求信号。 根据播放请求信号中包含的至少一个关键字,通过网络接口搜索网络服务器以找到至少一个多媒体文件。 下载从网络服务器发现的至少一个多媒体文件,并通过无线通信单元将下载的至少一个多媒体文件的部分发送到便携式设备。

    • A method for correcting keystone distortion is provided. The method is applied on a projector capable of correcting keystone distortion. The apparatus includes an angle detecting unit and a storage unit. The angle detecting unit detects an inclined angle and outputs a voltage value corresponding to the detected inclined angle. The storage unit stores a relationship between the inclined angles and the voltage values. The method includes determining the inclining angle according to the voltage value and the stored relationship; calculating the ratio of the length of the upper side of the projection area of a source image projected onto a projection surface to the length of the lower side of the projection area of a source image projected onto the projection surface, and inversing the ratio to determine a correction coefficient; and modifying the source image to display the source image onto the projection surface.
    • 提供了一种用于校正梯形失真的方法。 该方法应用于能够校正梯形失真的投影仪。 该装置包括角度检测单元和存储单元。 角度检测单元检测倾斜角度并输出与检测到的倾斜角度对应的电压值。 存储单元存储倾斜角度和电压值之间的关系。 该方法包括根据电压值和所存储的关系确定倾斜角; 计算投影到投影表面上的源图像的投影区域的上侧的长度与投影到投影表面上的源图像的投影区域的下侧的长度的比率,并且反映该比率以确定 校正系数; 并修改源图像以将源图像显示在投影表面上。
