| 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 |
| 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 |
| 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 |
| 20120127185 | SYSTEM AND METHOD FOR AN OPTIMIZED ON-THE-FLY TABLE CREATION ALGORITHM - A 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. | 05-24-2012 |
| 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 |
| 20140139537 | SYSTEM AND METHOD FOR AN EFFICIENT DISPLAY DATA TRANSFER ALGORITHM OVER NETWORK - Systems and methods for an efficient display data transfer algorithm over a network are disclosed. A compressed frame buffer update transmitted from a server via a network is received by a hardware decompression engine. The hardware decompression engine identifies one or more palette entries indicated in the compressed frame buffer update and determines whether the one or more palette entries is stored in a palette cache of the hardware decompression engine. If the one or more palette entries is not stored in the palette cache, the hardware decompression engine writes the one or more palette entries from an external palette memory to the palette cache. Decompressed display data is generated based on the compressed frame buffer update using the palette cache. The decompressed display data is written to an output buffer of the hardware decompression engine. | 05-22-2014 |
| 20140362097 | SYSTEMS AND METHODS FOR HARDWARE-ACCELERATED KEY COLOR EXTRACTION - Systems and methods for hardware-accelerated key color extraction are disclosed. An update corresponding to a portion of a digital representation of a display screen is received. Key color information for locations within the update is identified. A data structure code associated with the portion of the digital representation of the display screen is determined based on the identification of the key color information. The data structure code is provided to a data structure. During a scan of the frame buffer for display, the frame buffer is capable of being read according to the data structure. | 12-11-2014 |

| 20120229518 | OUTPUT OF VIDEO CONTENT - Technologies are generally described for systems and methods effective to output video content. In some examples, a content output device may be effective to receive a first request for first video content including a first identifier and a first category. The device may receive a zoom selection for the first video content including a first zoom level assigned to the first video content. The selection may be based on the first identifier or the first category. The device may store the zoom selection in a memory and receive a second request for second video content including a second identifier and a second category. The device may analyze the memory to determine a second zoom level for the second video content based on the first zoom level and the first identifier or the first category. The device may output the second video content at the second zoom level. | 09-13-2012 |
| 20120303583 | SEAMLESS APPLICATION BACKUP AND RECOVERY USING METADATA - Technologies are generally described for systems and methods effective to provide a seamless backup and recovery of applications using metadata. In an example, metadata can be defined to map data associated with an application and provide the relationship of the data to the application. From the metadata, a backup system can create a capsule containing application data, and a payload containing application related data. The capsule can contain not just the application data, but also configuration information, and access parameters. The capsule and payload can be associated together and saved by the backup system. In another example, to recover an application, a capsule and a payload can be retrieved, and using the metadata, the capsule can be unpacked to reinstall the application to the same state it was in when backed up, and the application related data can be restored from the payload. | 11-29-2012 |
