Two-way communications between a remote control unit and one or more devices in an audio/visual environment |
摘要 |
A remote control unit in an audio/visual system has a two-way communications link with one or more audio/visual devices. The bi-directional flow of information between the remote control unit and the audio/visual device(s) provides for the creation of remote control commands that are customized based upon the characteristics of the particular A/V device being controlled by the remote control unit. The remote control unit may additionally have another two-way communications link with one or more information-providing devices, such as a personal computer capable of accessing the Internet, that can provide the remote control unit with information available outside the audio/visual environment. The bi-directional flow of information of the two-way communications links is accomplished with a two-way infra-red link or a two-way serial link.
