Abstract
A data processing system connected to and controlling an infrared emitter may be utilized to control remote control devices such as video cassette recorders and cassette recorders, allowing the data processing system to program recording by such devices. The data processing system may, for example, be a set-top box located in proximity to remote controlled record/playback devices, relying on line-of-sight or reflected infrared signal transmission, or may be utilized in connection with suitably placed infrared repeaters. The data processing system may also be employed in conjunction with the 'server push' network technique, in which a data stream is transmitted to a subscribing client without intervention by the client. The data stream is monitored for user-defined data items. When detected, the data processing automatically controls the appropriate record/playback device to record a broadcast associated with the detected data item.
