Patent number: 11936705Abstract: Systems, devices, and methods for providing alternative content in audio-video streams are disclosed. A manifest data structure including data reflective of a plurality of content segments is generated. At least one alternative content indicator, each indicating one of said plurality of content segments as being an alternative content segment is obtained. The manifest data structure is modified to remove data reflective of those of said plurality of content segments that are not indicated by said one of said alternative content indicators as being an alternative content segment. Upon receiving a request from a client device to view alternative content, the modified manifest data structure is sent to the client device.Type: GrantFiled: May 28, 2021Date of Patent: March 19, 2024Assignee: MK Systems USA Inc.Inventors: Mark W. Robertson, Brian O'Neil, Rabih Filfili

Patent number: 11882314Abstract: Disclosed here are methods, systems, and devices for measuring visual quality degradation of digital content caused by an encoding process. There is received first data for a digital content item, which is not encoded by the encoding process, and second data for the digital content item, which is encoded by the encoding process. For a given artefact type, the first data and the second data are processed to obtain a first quality metric measuring visual quality degradation in the digital content item attributable to the given artefact type caused by the encoding process. A stored mapping corresponding to the given artefact type is applied to the first quality metric to obtain a second quality metric which measures visual quality degradation in the digital content item attributable to the given artefact type caused by the encoding process and approximates subjective assessment of the digital content item by a human visual system.Type: GrantFiled: July 11, 2022Date of Patent: January 23, 2024Assignee: MK Systems USA Inc.Inventor: Jean Kypreos

Patent number: 11693915Abstract: Interactive editing of a web application at a user end station is described. The user end station dynamically loads into a running instance of the web application an interactive editor that allows editing of one or more user interface (UI) components of that running instance of the web application. A selection of a DOM element of the web application is received and a UI component that corresponds to the selected DOM element is determined. A set of parameters associated with the determined UI component is also determined. A value editor is displayed that is configured to display for at least one of the set of parameters a value and allows for that value to be modified. A modification of at least the value of the at least one of the set of parameters is received and the running instance of the web application is updated to reflect the modified value.Type: GrantFiled: February 19, 2021Date of Patent: July 4, 2023Assignee: MK Systems USA Inc.Inventors: Oliver Unter Ecker, Nickolas Westman

Patent number: 10498368Abstract: A client-side FEC selection system involves pre-generating FEC data for a plurality of media segment streams based on a number of FEC configuration settings at a server. Metadata relative to the FEC data may be provided to a client device via appropriate manifest files or other mechanisms, whereupon the client device is operative to select and request a suitable FEC data fragment responsive to monitoring various network characteristics.Type: GrantFiled: November 2, 2015Date of Patent: December 3, 2019Assignee: MK Systems USA Inc.Inventors: Edwin Salomons, Alan Bishop
