  • Patent number: 12706121
    Abstract: A method for searching for relevant temporal segments within digital media assets is disclosed. The method may include receiving multiple digital media assets to be considered when responding to search requests, identifying respective properties for the multiple digital media assets, receiving a search request that includes at least one search parameter, and identifying, a subset of the multiple digital media assets that correspond to the at least one search parameter. The method may further include parsing the subset of the multiple digital media assets to identify respective temporal segments within corresponding ones of the subset, filtering the subset based on respective relevance scores, and outputting a user interface that displays, respective first information that is based on the subset, and respective second information that is based on the respective temporal segments.
    Type: Grant
    Filed: May 5, 2025
    Date of Patent: August 11, 2026
    Assignee: Apple Inc.

  • Patent number: 11178202
    Abstract: In one embodiment, systems, methods and non-transitory machine readable media detect differences between the rate of production, by a server, of media segments identified in an HTTP compliant playlist and the rate of consumption, by a client device, of the media segments in streaming media content. These differences, once detected, can be used to adjust a playback rate at the client to reduce the difference between the server rate and the client rate. This detection can be used in low latency streaming media contexts in which the client device is playing back content that is live, such as a live sports event happening during the playback by the client device. The adjustment of the client's playback rate can avoid running out of buffered media segments (when the client's rate is much faster than the server's rate) and can avoid increasing latency at the client device and overloading a buffer with too many media segments (when the client's rate is much slower than the server's rate).
