  • Patent number: 11716520
    Abstract: The disclosed computer-implemented method includes determining, for multiple different media items, a current time scale at which the media items are encoded for distribution, where at least two of the media items are encoded at different frame rates. The method then includes identifying, for the media items, a unified time scale that provides a constant frame interval for each of the media items. The method also includes changing at least one of the media items from the current time scale to the identified unified time scale to provide a constant frame interval for the changed media item(s). Various other methods, systems, and computer-readable media are also disclosed.

  • Publication number: 20220408056
    Abstract: The disclosed method includes accessing video content encoded at a specified frame rate, and determining a refresh rate for an electronic display on which the video content is to be presented. The method next includes specifying a time interval for the video content over which frame rate conversion is to be applied to synchronize the video content frame rate with the electronic display refresh rate. The method also includes presenting the video content on the electronic display where the playback speed is adjusted for a first part of the interval. At this adjusted speed, the interval is played back using original video frames and multiple frame duplications. The presenting also adjusts playback speed of a second part of the interval. At the adjusted speed, the interval is played back using the original frames and a different number of frame duplications. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 9984000
    Abstract: A non-transitory computer-readable storage medium may include instructions that cause a system to perform operations, the operations may include receiving an operation associated with data and managing storage of the data on a first storage medium of an electronic device and in a cache on a second storage medium of the electronic device based on the operation and a cache policy. The cache policy may be based on one or more characteristics of the data that include a duration since a previous access of the data.
