    • In a stream reception device, before the user operates an input section (15), a control section (12) uses locational information of each of n number of selected stream transmission stations (2) to generate and send a distribution request (R), which is data for requesting distribution of a stream (ST) stored in each of the stream transmission stations (2). Then, each stream (ST) is buffered in a stream storage section (14) sequentially from a reproduction start portion thereof. Then, in the case where a stream (ST) to be a target is stored, the control section (12) reads the target stream (ST) from the stream storage section (14), sequentially from the reproduction start portion thereof, and reproduces the target stream (ST), in response to an operation on the input section (15).
    • 在流接收装置中,在用户操作输入部分(15)之前,控制部分(12)使用n个选择的流传输站(2)中的每一个的位置信息来生成和发送分发请求(R) 其是用于请求分配存储在每个流传输站(2)中的流(ST)的数据。 然后,每个流(ST)从其再现起始部分顺序地缓冲在流存储部分(14)中。 然后,在存储作为对象的流(ST))的情况下,控制部(12)从流存储部(14)依次从其再现开始部分读取目标流(ST),并再现 所述目标流(ST)响应于在所述输入部分(15)上的操作。

    • A video display system for suppressing variations of a video image display position and improving viewing comfort includes: a projector (1100) which projects a video projection light; and a screen unit (1150) which receives the video projection light and displays the video image. The screen unit (1150) includes first and second light detection units (1161 and 1162) which detect the received video projection light. The projector (1100) includes a control unit (1205) and an adjustment unit (106) which derive displacement in the display position of the video image based on the light detection results of the first and second light detection units (1161 and 1162) and control the output mode of the video projection light so as to suppress the displacement.
    • 一种用于抑制视频图像显示位置的变化并改善观看舒适度的视频显示系统包括:投射视频投影光的投影仪(1100); 以及接收视频投影光并显示视频图像的屏幕单元(1150)。 屏幕单元(1150)包括检测接收到的视频投影光的第一和第二光检测单元(1161和1162)。 投影仪(1100)包括基于第一和第二光检测单元(1161和1162)的光检测结果导出视频图像的显示位置的位移的控制单元(1205)和调整单元(106),以及 控制视频投影光的输出模式以抑制位移。

    • A video/sound signal switching and distributing device makes connections to a plurality of video/sound signal receiving devices to be connected at startup of a system and performs authentication between itself and the plurality of video/sound signal receiving devices, thereby acquiring key selection information about a video/sound signal transmitting device and holding the key selection information. Even when another video/sound signal receiving device is connected to the video/sound signal transmitting device while one video/sound signal is already in the middle of displaying a view of the video/sound signal, the video/sound signal transmitting device and the video/sound signal switching and distributing device can again establish a connection without redoing mutual authentication. Hence, disconnection and re-connection of the video/sound signal can be performed without interruption of the video/sound signal being displayed for viewing purpose.
    • 视频/声音信号切换和分配设备使多个视频/声音信号接收设备的连接在系统启动时被连接,并且在其自身与多个视频/声音信号接收设备之间进行认证,从而获取密钥选择信息 关于视频/声音信号发送装置并保持密钥选择信息。 即使当一个视频/声音信号已经在显示视频/声音信号的视图的中间,另一个视频/声音信号接收装置连接到视频/声音信号发送装置时,视频/声音信号发送装置和 视频/声音信号交换和分配设备可以重新建立连接,而无需重做相互认证。 因此,视频/声音信号的断开和重新连接可以在不中断视频/声音信号被中断的情况下进行观看。
