An information handling system includes a central processor, a read only memory for storing microcode, a random access memory for storing instructions and data processed by the central processor, an I/O adapter for transferring data to and from peripheral devices, a user interface adapter for communicating with user devices such as a keyboard and a cursor control device, and a display adapter for converting data to be displayed to a form suitable for presentation on a display device, the display adapter including a video frame buffer architecture which allows a page mode to be used for fast screen update using commercially available chips wherein independently addressable islands on the chips are individually addressed to increase data transmission bandwidth.

Information handling system including mapping of graphics display data

A video game cartridge that can be plugged into a video game machine to enable a user to request and play a video game for a predetermined number of video frames. The cartridge has a receiver for receiving the video game program and the predetermined frame count in response to a request from the user. The program and frame count is then stored in a memory of the cartridge. Finally, the cartridge has a counter which changes its value when the user is actively playing the video game program. The counter ceases to change its value when the user is not playing the video game program. When the counter reaches a predetermined limit, the user is no longer authorized to play the video game program.

Universal electronic video game renting/distributing system

The present invention provides an integrated display system for multi-media workstations wherein graphics image and video data are merged in a single frame buffer. The integrated display system employs 3-port VRAMs with a first serial access port for display data output, and a random access port for graphics data, a second serial access for video data input. The display system includes a single frame buffer memory system for a multi-media workstation which operates compatibly with display systems and logic designed for dual frame buffer systems and it uses the 3-port VRAM in combination with a means incorporating improved input locking, video update or refresh, and encoded video data input stream.

Integrated single frame buffer memory for storing graphics and video data

An apparatus and method for displaying non-obscured pixels in a multiple-media motion video environment (dynamic image management) possessing overlaid windows. In an encoding process, only boundary values and identification values corresponding to each window on a screen are saved in memory of a hardware device. In a decoding process, the hardware device utilizes these initial boundary values saved in memory in such a way that when incoming video data enters the hardware device, the hardware device need only compare the incoming video data's identification with the identification saved in memory. The hardware device includes: compare logic devices, counters, minimal memory devices, a control logic block, and a driver.
