Abstract
Abstract Home entertainment center interface apparatus providing remote database access and access coordination is disclosed. The interface can, alternatively, be installed directly on the PCI bus in the computer. The interface provides remote access to the database in response to signals from an RF remote control transmitter. The transmitter can be added as a plug-compatible unit to upgrade an existing video control device. A supplemental chat window is generated by a further plug-compatible upgrade unit in response to address and command signals modulating a dedicated carrier frequency on the cable.
