An entertainment system has a personal computer as the heart of the system with a large screen VGA quality monitor as the display of choice. The system has digital satellite broadcast reception, decompression and display capability with multiple radio frequency remote control devices which transmit self identifying signals and have power adjustment capabilities. These capabilities are used to provide context sensitive groups of keys which may be defined to affect only selected applications running in a windowing environment. In addition, the remote control devices combine television and VCR controls with standard personal computer keyboard controls. A keyboard remote also integrates a touchpad which is food contamination resistant and may also be used for user verification. Included in the system is the ability to recognize verbal communications in video signals and maintain a database of such text which is searchable to help identify desired programming in real time.

Triple-buffering video memory in a computer graphics controller improves the quality of full-motion video converted for display on a computer monitor. Buffer size, organization, and access cycles prevent converted data representing a new video frame from overwriting a buffer in memory that contains converted data representing a video frame currently being displayed. The access cycles also ensure all data representing a video frame is displayed. The video memory is partitioned into three logical buffers to hold the converted data, the buffers are arranged in a logical ring sequence for read and write access, and the data in a buffer is repeatedly read until the next buffer in the sequence is full of data and ready to be read. In addition, the buffering is adaptable to different resolutions as the size of the buffers is determined by the value of the resolution each time the video conversion is initiated.
