Patent number: 8681811Abstract: Techniques for use within computer systems that communicate with multiple different terminal systems using multiple different terminal protocols are disclosed. In one embodiment, a partial protocol converter module is installed in a computer server system to enable the computer server system to communicate with terminal systems that use terminal protocol other than the terminal protocol used natively by the computer server system. The partial protocol converter module directly accesses a screen buffer in the computer server system that is associated with the terminal systems that use terminal protocol other than the terminal protocol used natively by the computer server system. The partial protocol converter module detects updates to the screen buffer and encodes these display screen updates into a message using the native protocol used by the terminal system and then transmits that encoded message to the terminal system.Type: GrantFiled: January 27, 2009Date of Patent: March 25, 2014Assignee: nComputing Inc.Inventors: Sergey Kipnis, Klaus A.

Patent number: 8471860Abstract: Graphics display adapters for driving multiple display monitors have become very popular. Graphics display adapters that drive multiple monitors can be used to provide terminal services to multiple independent terminals or be used to provide multiple displays to a single user. Generating video signals for multiple display systems puts a heavy burden on the video memory system since multiple different video signal generators may read from associated frame buffers in a shared video memory system. In one disclosed embodiment, a plurality of video memory read triggers are provided wherein at least two of which are staggered to reduce the load on the video memory system. In response to each read trigger, display data is read from a frame buffer to an associated video signal generation circuit. Each video signal generation circuit then provides a display signal to an associated display screen in a multi-screen environment.Type: GrantFiled: July 13, 2012Date of Patent: June 25, 2013Assignee: nComputing Inc.Inventor: Subir Ghosh

Patent number: 8411740Abstract: To conserve communication channel bandwidth, video information must often be compressed in low bandwidth environments. To significantly reduce bandwidth usage, a first disclosed embodiment proposes transmits a reduced color depth image initially and then later transmitting additional color depth information when the image becomes static. In this manner, a reduced color image is displayed when an image is dynamic but a full color image is displayed when the image becomes static. Note that the additional color information is transmitted only when bandwidth is has become less utilized since updated image information is no longer being transmitted since the image has become static. The additional color depth information may be stored in the same buffer or within a different buffer in the receiving system. A second embodiment delays additional color depth information and also spatially reduces the additional color depth information.Type: GrantFiled: September 9, 2008Date of Patent: April 2, 2013Assignee: nComputing Inc.Inventors: Yury Karlov, Nikolay Kovach

Publication number: 20120239740Abstract: Thin-client terminal systems allow server computer systems to be shared by multiple computer users. However, thin-client terminal systems that use analog signals can only be placed a limited distance from the main server computer system. On the other hand, thin-client terminal systems that rely purely on digital signals can be expensive to produce. A thin-client multiplier that combines the two different approaches communicates digitally with main server computer system such that it can be placed any distance from the main server computer system. The thin-client multiplier also provides output information received from the server system and electrical power to analog thin-client terminal systems and receives input information from the analog thin-client terminal systems. The received input information is provided to the server system for processing.Type: ApplicationFiled: October 1, 2010Publication date: September 20, 2012Applicant: nComputing Inc.Inventor: Gabriele Sartori

Publication number: 20120188460Abstract: The video output system in a computer system reads pixel information from a frame buffer to generate a video output signal. However, the video output system must often compete with other memory users in order to access a frame buffer in a shared memory system. When memory bandwidth resources are limited, the performance of a computer system will suffer. To reduce the performance drop, a dynamic color mode switching system has been introduced. The dynamic color mode switching system detects when memory bandwidth resources are limited and then instructs the video output system to switch to a color mode that reduces the amount of reads from the memory system without any user intervention.Type: ApplicationFiled: January 21, 2011Publication date: July 26, 2012Applicant: nComputing Inc.Inventors: Franco Eulogio Mau, Sangyong Park, Anita Chowdhry

Publication number: 20120120320Abstract: The video output system in a computer system reads pixel information from a frame buffer to generate a video output signal. In addition, a full-motion video may also be displayed. Reading from both the frame buffer and the full-motion video buffer when displaying the full-motion video window wastes valuable memory bandwidth. Thus, the disclosed system provides a system and methods for identifying where the video output system must read from the frame buffer and where it must read from the full-motion video buffer while minimizing the amount of area it reads from both the frame buffer and the full-motion video buffer.Type: ApplicationFiled: November 16, 2010Publication date: May 17, 2012Applicant: nComputing Inc.Inventors: Anita Chowdhry, Subir Ghosh

Publication number: 20120098864Abstract: The video output system in a computer system reads pixel information from a frame buffer to generate a video output signal. In addition, full-motion video may also be displayed in a window defined in the frame buffer. If the native resolution of the full-motion video is larger than the window defined in said frame buffer then valuable memory space and memory bandwidth is being wasted by writing said larger full-motion video in a memory system (and later reading it back) when some data from the full-motion video will be discarded. Thus, a video pre-processor is disclosed to reduce the size of the full-motion video before that full-motion video is written into a memory system. The video pre-processor will scale the full-motion video down to a size no larger than the window defined in the frame buffer.Type: ApplicationFiled: October 20, 2010Publication date: April 26, 2012Applicant: nComputing Inc.Inventors: Anita Chowdhry, Subir Ghosh
