  • Publication number: 20240242413
    Abstract: Systems, methods, and computer-readable media are disclosed for systems and methods for automated generation and presentation of sign language avatars for video content. Example methods may include determining, by one or more computer processors coupled to memory, a first segment of video content, the first segment including a first set of frames, first audio content, and first subtitle data, where the first subtitle data comprises a first word and a second word. Methods may include determining, using a first machine learning model, a first sign gesture associated with the first word, determining first motion data associated with the first sign gesture, and determining first facial expression data. Methods may include generating an avatar configured to perform the first sign gesture using the first motion data, where a facial expression of the avatar while performing the first sign gesture is based on the first facial expression data.

  • Patent number: 11659217
    Abstract: Techniques are described for detecting desynchronization between an audio component and a video component of a media presentation. Feature sets may be determined for portions of the audio component and portions of the video component, which may then be used to generate correlations between portions of the audio component and portions of the video component. Synchronization may then be assessed based on the correlations.

  • Patent number: 11610610
    Abstract: Systems and methods are provided for detecting and correcting synchronization errors in multimedia content comprising a video stream and a non-original audio stream. Techniques for directly detecting synchronization of video and audio streams may be inadequate to detect synchronize errors for non-original audio streams, particularly where such non-original audio streams contain audio not reflective of events within the video stream, such as speaking dialog in a different language than the speakers of the video stream. To overcome this problem, the present disclosure enables synchronization of a non-original audio stream to another audio stream, such as an original audio stream, that is synchronized to the video stream. By comparison of signatures, the non-original and other audio stream are aligned to determine an offset that can be used to synchronize the non-original audio stream to the video stream.

  • Publication number: 20180336282
    Abstract: The present disclosure is related to a system and method for providing personalized news feed on a mobile application installed in a computing device of a user. The said mobile application includes a computer readable instruction for accessing the news feed. The computing device is communicably coupled to a digital content server which stores a plurality of news contents pre-stored in the said digital content server. The method comprises receiving user activity data at the digital content server from the computing device, determining user preferences for one or more category of news content depending upon the user activity data, ranking the one or more news content to compile the news feed, and transmitting the news feed to the computing device of the user wherein the transmittal of the news feed takes place on a request from the computing device.
