Publication number: 20230121413Abstract: In examples, a device's native input interface (e.g., a soft keyboard) may be invoked using interaction areas associated with image frames from an application, such as a game. An area of an image frame(s) from a streamed game video may be designated (e.g., by the game and/or a game server) as an interaction area. When an input event associated with the interaction area is detected, an instruction may be issued to the client device to invoke a user interface (e.g., a soft keyboard) of the client device and may cause the client device to present a graphical input interface. Inputs made to the presented graphical input interface may be accessed by the game streaming client and provided to the game instance.Type: ApplicationFiled: September 20, 2022Publication date: April 20, 2023Inventors: Prakash Yadav, Charu Kalani, Stephen Holmes, David Wilson, David Le Tacon, James Lewis van Welzen

Patent number: 11617951Abstract: A game summary may be produced using an event log of in-game events and corresponding game content based on game data associated with a gameplay session(s). The event log may include metadata that indicates times of in-game events and associations between in-game events and game content items that capture the in-game events. A user may interact with in-game events with temporal context, allowing for more informed selections and a better understanding of the gameplay session. Using the event log, a game summary may provide such features as a timeline to convey relative timing of in-game events, a list of in-game events, a map of a virtual environment of the game that is temporally annotated based on in-game events, game status information, and statistical and performance information. A game summary may show trends over time and/or game sessions and convey information for selected sets of players, such as teams.Type: GrantFiled: June 28, 2021Date of Patent: April 4, 2023Assignee: NVIDIA CorporationInventors: James Lewis van Welzen, Glenn R. Cochran, Jean Wang, Po-Shih Wang, Jeffrey David Weintraub, Toshant Sharma, Shyam Raikar

Publication number: 20230071358Abstract: In various examples, natural language processing may be performed on text generated by a game to extract one or more in-game events from the game. The system (e.g., a client device and/or server) may receive the text in the form of one or more strings generated by a game application. The system may then extract one or more in-game events from the text using natural language processing. The game may include the text in a message it sends to the system (e.g., using an Application Programming Interface (API)) and/or in a game log entry or notification. The text may be generated based at least on the game determining one or more conditions are satisfied in the gameplay (e.g., victory, points scored, milestones, eliminations, item acquisition, etc.). The text may be mapped to event templates, which may then be used to extract parameters of events therefrom.Type: ApplicationFiled: September 7, 2021Publication date: March 9, 2023Inventors: James Lewis van Welzen, Prakash Yadav, Charu Kalani, Jonathan White, Shyam Raikar, Stephen Holmes, David Wilson

Patent number: 8958688Abstract: Aspects of performing smooth backwards playback in a DVD system are described. The aspects include reconstructing frame data for every frame in a set of frames of an original playback, the set of frames preceding a currently displayed frame. Further included is the utilization of at least seven frame buffers to store frame data during the reconstructing step. The reconstructed frame data is then displayed in reverse order of the original playback for the set of frames.Type: GrantFiled: November 26, 2001Date of Patent: February 17, 2015Assignee: Nvidia CorporationInventors: James Lewis van Welzen, Brian Dennis Falardeau, Jonathan Barton White

Patent number: 8320749Abstract: Methods, systems and computer-readable medium for changing video playback speed are disclosed. Video playback speed may be changed by determining a first frame rate and a second frame rate for which a frame rate transition is to be made. An instantaneous frame rate is calculated to produce a calculated instantaneous frame rate, wherein the calculated instantaneous frame rate is between the first frame rate and the second frame rate. A timestamp of a frame is adjusted based on the calculated instantaneous frame rate to produce an adjusted timestamp. Graphical data for the frame is provided in accordance with the adjusted timestamp to enable display of the frame. Thereafter, the frame may be displayed in accordance with the adjusted timestamp.Type: GrantFiled: May 22, 2007Date of Patent: November 27, 2012Assignee: NVIDIA CorporationInventors: James Lewis van Welzen, Brian Dennis Falardeau, Jonathan Barton White

Patent number: 7231138Abstract: Aspects of performing single frame backwards playback in a DVD system are described. The aspects include receiving a signal indicating selection of a single frame reverse function. Frame data for a preceding frame of an original playback is then reconstructed while utilizing memory sufficient to support the reconstruction. The reconstructed frame data of the preceding frame is then displayed.Type: GrantFiled: November 26, 2001Date of Patent: June 12, 2007Assignee: Nvidia CorporationInventors: James Lewis van Welzen, Brian Dennis Falardeau, Jonathan Barton White

Patent number: 6177944Abstract: A method and apparatus for a computer graphics rendering system which slices the traditional geometry pipeline into two phases to improve overall graphics system utilization is described. The graphics system consists of a host processor and a graphics adapter. The host creates work items and feeds them to the graphics adapter. In the two phase method, the first phase computes the clipping status and immediately returns this status information, before completion of the actual clipping, to the application running on the host processor to minimize stalling the host processor and hence the application. The second phase performs the rest of the work necessary to draw the objects on the screen. The advantage of two phase method is that the host processor minimizes its wait (but only for model/view transformation and clipping status determination) for a return status from the graphics adapter for the current work item and gets to create the next work item from the application sooner.Type: GrantFiled: September 18, 1998Date of Patent: January 23, 2001Assignee: International Business Machines CorporationInventors: Mark Christopher Fowler, Kirk Steffen Haskell, Robert Spencer Horton, Thomas Yu-Kiu Kwok, Steve Mastrianni, Chandrasekhar Narayanaswami, Bengt-Olaf Schneider, Mark van Horn, James Lewis van Welzen

Patent number: 6052129Abstract: While executing the standard graphics processing steps, problem polygons (i.e., those outside of a defined clip volume) are buffered for later processing, while the standard graphics processing continues, without the need for periodically reformatting data and performing clipping. After either a predefined number of polygons have been stored at the buffer location, or at such time as a change in the rendering state occurs, the buffered polygons are clipped.Type: GrantFiled: October 1, 1997Date of Patent: April 18, 2000Assignee: International Business Machines CorporationInventors: Mark Christopher Fowler, Kirk Steffen Haskell, Robert Spencer Horton, Thomas Yu-Kiu Kwok, Chandrasekhar Narayanaswami, Bengt-Olaf Schneider, Mark Van Horn, James Lewis van Welzen

Patent number: 6052128Abstract: An image to be clipped is decomposed into its edges and the edges simultaneously clipped by multiple execution units of a SIMD computer along pairs of parallel clip planes. Successive parallel operations are performed on polygons recomposed using the clipped output edges, until all clipping has been performed.Type: GrantFiled: July 23, 1997Date of Patent: April 18, 2000Assignee: International Business Machines Corp.Inventors: Chandrasekhar Narayanaswami, Bengt-Olaf Schneider, James Lewis van Welzen
