  • Patent number: 11342002
    Abstract: An automated solution to determine suitable time ranges or timestamps for captions is described. In one example, a content file includes subtitle data with captions for display over respective timeframes of video. Audio data is extracted from the video, and the audio data is compared against a sound threshold to identify auditory timeframes in which sound is above the threshold. The subtitle data is also parsed to identify subtitle-free timeframes in the video. A series of candidate time ranges is then identified based on overlapping ranges of the auditory timeframes and the subtitle-free timeframes. In some cases, one or more of the candidate time ranges can be merged together or omitted, and a final series of time ranges or timestamps for captions is obtained. The time ranges or timestamps can be used to add additional non-verbal and contextual captions and indicators, for example, or for other purposes.

  • Patent number: 10764620
    Abstract: Systems and methods of the present disclosure provide for dynamic delay equalization of related media signals in a media transport system. Methods include receiving a plurality of related media signals, transporting the related media signals along different media paths, calculating uncorrected propagation delays for the media paths, and delaying each of the related media signals by an amount related to the difference between the longest propagation delay (of the uncorrected propagation delays) and the uncorrected propagation delay of the related media signal/media path. Calculating the uncorrected propagation delays and delaying the related media signals may be performed in response to a change to the propagation delay of at least one of the related media signals/media paths. Additionally or alternatively, calculating the uncorrected propagation delays and delaying the related media signals may be performed while transporting the related media signals.

  • Patent number: 10623789
    Abstract: Methods, systems, and computer programs for measuring quality of multimedia delivery to a client are presented. A method includes operations for embedding video markers in a video stream of a multimedia stream, and embedding audio markers in an audio stream of the multimedia stream. The video stream and the audio stream are then transmitted separately to the client. Further, video markers received at the client are extracted from the transmitted video stream, and audio markers received at the client are extracted from the transmitted audio stream. A measure of the audio-video synchronization quality is obtained by determining a quantifiable time difference between the video stream and the audio stream received at the client, where the quantifiable time difference is calculated based on the extracted video markers and the extracted audio markers.

  • Patent number: 10477339
    Abstract: Embodiments are described for an adaptive audio system that processes audio data comprising a number of independent monophonic audio streams. One or more of the streams has associated with it metadata that specifies whether the stream is a channel-based or object-based stream. Channel-based streams have rendering information encoded by means of channel name; and the object-based streams have location information encoded through location expressions encoded in the associated metadata. A codec packages the independent audio streams into a single serial bitstream that contains all of the audio data. This configuration allows for the sound to be rendered according to an allocentric frame of reference, in which the rendering location of a sound is based on the characteristics of the playback environment (e.g., room size, shape, etc.) to correspond to the mixer's intent.
