20120188460 | SYSTEM AND METHOD FOR DYNAMIC VIDEO MODE SWITCHING - 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. | 07-26-2012 |

20120120320 | SYSTEM AND METHOD FOR ON-THE-FLY KEY COLOR GENERATION - 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. | 05-17-2012 |
20120098864 | SYSTEM AND METHOD FOR DOWNSIZING VIDEO DATA FOR MEMORY BANDWIDTH OPTIMIZATION - 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. | 04-26-2012 |

20110080519 | SYSTEM AND METHOD FOR EFFICIENTLY PROCESSING DIGITAL VIDEO - In a digital video processing system for processing full-motion video in computer terminal systems, two main rendering paths are created for a computer terminal system: a screen buffer path and a full-motion video path. The screen buffer path renders a desktop display from a screen buffer within the terminal system. The full-motion video path decodes a video stream and then processes the decoded video stream with a video processing pipeline to fit the video frames within a destination video window within the desktop display. The video processing pipeline performs clipping, blending, chroma resampling, resizing, and color converting of the video frames in pipelined stages with minimal memory accesses. A video adapter then combines the desktop display with the processed digital video for a final terminal display. | 04-07-2011 |

20090066840 | SYSTEM AND METHOD FOR LOW BANDWIDTH DISPLAY INFORMATION TRANSPORT - 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. | 03-12-2009 |
