Publication number: 20220312021Abstract: A method and apparatus for encoding surveillance video where one or more regions of interest are identified and the encoding parameter values associated with those regions are specified in accordance with intermediate outputs of a video analytics process. Such an analytics-modulated video compression approach allows the coding process to adapt dynamically based on the content of the surveillance images. In this manner, the fidelity of the region of interest is increased relative to that of a background region such that the coding efficiency is improved, including instances when no target objects appear in the scene. Better compression results can be achieved by assigning different coding priority levels to different types of detected objects.Type: ApplicationFiled: November 5, 2021Publication date: September 29, 2022Applicant: CheckVideo LLCInventors: Lai-Tee Cheok, Nikhil Gagvani

Patent number: 10334278Abstract: A method of decoding, composing and rendering a scene. First information is obtained, the first information including a part of a MPEG-4 BIFS scene description stream and at least one coded MPEG-4 media stream. The first information is decoded by invoking a BIFS scene decoder and one or more specific media decoders that are required by the scene. Second information is obtained, the second information including a second part of a BIFS scene description stream that contains a reference to an external application. The second information is decoded by invoking the BIFS scene decoder and an external application decoder. An integrated scene is composed, the integrated scene including one or more decoded MPEG-4 media objects and one or more external application objects specified in the decoded scene descriptions streams. The composed integrated scene is rendered on a display.Type: GrantFiled: October 17, 2016Date of Patent: June 25, 2019Assignee: AT&T INTELLECTUAL PROPERTY II, L.P.Inventors: Lai-tee Cheok, Atul Puri, Robert Schmidt

Publication number: 20120128334Abstract: An apparatus and method for combining multimedia data are provided. The method includes obtaining first multimedia content from a first source, obtaining second multimedia content from a second source, selectively combining the first multimedia content with the second multimedia content, and outputting the selectively combined multimedia content. According to implementations of the invention, selected portions and/or fragments of multimedia content may be mashed up rather than the entirety of the multimedia content from either or both sources. Also, the mashup of the multimedia content may be varied and adapted based on the characteristics of the device performing the mashup as well as the characteristics of the available transport mechanism. Finally, implementations of the invention provide for flexible transformation and precise synchronization among multimedia elements.Type: ApplicationFiled: November 15, 2011Publication date: May 24, 2012Applicant: SAMSUNG ELECTRONICS CO.
