Patent number: 10244022Abstract: Described is a technology by which code, such as an untrusted web application hosted in a browser, provides content through an interface for playback by an application environment, such as an application environment running in a browser plug-in. Content may be in the form of elementary video, audio and/or script streams. The content is in a container that is unpackaged by the application code, whereby the content may be packaged in any format that the application understands, and/or or come from any source from which the application can download the container. An application environment component such as a platform-level media element receives information from an application that informs the application environment that the application is to provide media stream data for playback. The application environment requests media stream data (e.g., samples) from the application, receives them as processed by the application, and provides the requested media stream data for playback.Type: GrantFiled: July 22, 2014Date of Patent: March 26, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Sam J George, Gilles Khouzam, Michael R Harsh, Gurpratap Virdi, John Gossman, Michael John Hillberg, Greg D Schechler, Donald D Karlov, Eldar A Musayev, Wenbo Zhang, Serge Smimov, Federico Schliemann, Lawrence Wayne Olson, Akshay Johar

Patent number: 8266311Abstract: Strategies are described for transmitting control information from a host module to a client module. The host module transmits the control information in-band along with a stream of media content information packets. The control information can be used to govern the operation of the client module. In one case, the control information alerts the client module to a discontinuity in streams, which may be the result of the user changing channels via the host or client module, etc., issuing a seek instruction, and so forth. Transmitting the control information in in-band fashion is advantageous because it reduces the need for complex linking between the control information and the associated content information.Type: GrantFiled: July 29, 2004Date of Patent: September 11, 2012Assignee: Microsoft CorporationInventors: Gurpratap Virdi, Jeffrey A.

Patent number: 8248423Abstract: A media processing framework includes multiple media processing paths. At least one of the media processing paths includes a media processing pipeline which is in-process with respect to an application which interacts with the media processing pipeline. At least one other of the media processing paths includes a media processing pipeline which is out-of-process with respect to the application. The application can specify a custom plug-in presenter module to be set in either the in-process media processing pipeline or the out-of-process media processing pipeline. The application need not be “aware” of the pipeline that is being used, whether the pipeline is in-process or out-of-process, or the security level that is applied to the media processing pipeline. Both the in-process and the out-of-process media processing pipelines can supply media information to a presentation processor, such as a compositing engine.Type: GrantFiled: January 28, 2011Date of Patent: August 21, 2012Assignee: Microsoft CorporationInventors: Gareth Howell, Thobias M. Jones, Nishad Mulye, Gurpratap Virdi

Patent number: 7925774Abstract: The present disclosure relates to playback of video/audio streaming media data to provide a substantially glitch-free experience. The system adapts the media stream to the user connection in order to choose the most desirable stream to avoid glitches. For example, in the case where there is interference (e.g., a microwave being used near a wireless device), the quality of the media stream is lowered. In one embodiment, an index file is used to make logical decisions about which media stream to choose in order to minimize glitches. The index file can take different forms, but, generally, includes characteristics about the available media streams. Example characteristics include the bit rates of the media streams and quality information about the media streams.Type: GrantFiled: August 7, 2008Date of Patent: April 12, 2011Assignee: Microsoft CorporationInventors: Wenbo Zhang, Serge Smirnov, Kishore Kotteri, Gurpratap Virdi, Eldar Musayev, Florin Folta
