    • An image display system capable of displaying two distinct images at the same time. One image is shown on an image display device such as a television or computer monitor which is coupled to the image display system. The other image is shown on a remote control (170) included in an image display system. A docking station is also part of the image display system. It is connected by standard audio-visual coaxial cable to the TV and associated video devices and sends compressed digital video signal information to the video remote control (170) by RF communication. Both the docking station and the video remote control (170) have RF antennas and receivers (112, 152) capable of sending digital RF signals. Digital command and information signals are exchanged between the docking station and video remote control (170) to allow control from the remote control of the functions of the TV and other video devices. The remote control (170) has a learning mode with on-screen feedback making the image display system backward and forward compatible with a wide array of image display devices. The invention is thought to be particularly useful for networked computer televisions.
    • 能够同时显示两个不同图像的图像显示系统。 一个图像显示在耦合到图像显示系统的诸如电视或计算机监视器的图像显示设备上。 另一图像显示在包括在图像显示系统中的遥控器(170)上。 对接站也是图像显示系统的一部分。 它通过标准视听同轴电缆连接到电视和相关视频设备,并通过RF通信将压缩的数字视频信号信息发送到视频遥控器(170)。 对接站和视频遥控器(170)都具有能够发送数字RF信号的RF天线和接收器(112,152)。 在对接站和视频遥控器(170)之间交换数字命令和信息信号,以允许远程控制TV和其他视频设备的功能的控制。 遥控器(170)具有屏幕反馈的学习模式,使得图像显示系统向后和向前兼容多种图像显示装置。 本发明被认为对联网计算机电视特别有用。
