  • Patent number: 10290322
    Abstract: An audio and video synchronizing perceptual model is described that is based on how a person perceives audio and/or video (e.g., how the brain processes sound and/or visual content). The relative emotional impact associated with different audio portions may be employed to determine transition points to facilitate automatic synchronization of audio data to video data to create a production that achieves a particular overall emotional effect on the listener/viewer. Various processing techniques of the perceptual model may utilize perceptual characteristics within the audio portions to determine a transition point for automatic synchronization with video data.

  • Patent number: 9013631
    Abstract: Methods and apparatus for processing and displaying caption information associated with a video program are provided. The caption information is extracted from a video signal and different captions are rendered in sequence for different segments of the video program. A plurality of the different captions is blended in a form for simultaneous display superimposed on video images during one of the different segments of the video program. The different captions may be the latest caption corresponding to the current segment of video and a previous caption corresponding to a previous video segment. These different captions can be displayed such that they overlie each other and such that their opacity is different. In this manner, a viewer is able to have a prolonged period of time to read captions and can readily distinguish the current caption from the previous caption.

  • Patent number: 9001275
    Abstract: HDMI is a digital audio and video communications protocol commonly used in consumer electronics. HDMI is particularly synonymous with high fidelity audio and video. Even though HDMI is a digital communications protocol, the audio quality can be impaired by analog signal impairments and distortions even if there are no digital decoding errors. In particular, the very process by which the audio is converted from Digital (HDMI) to human audible “Analog Audio” can be prone to errors. This occurs when the Digital to Analog Converter (DAC) clock, which is derived from the HDMI TMDS clock or HDMI source, is “distorted” due to its jitter, resulting in erroneous sampling or outputting of vital audio samples, thereby reducing the audio quality of the experience. The present invention reduces the jitter on the TMDS clock, and hence the audio DAC clock, resulting in lower audio distortion.

  • Publication number: 20150062429
    Abstract: Disclosed herein are systems, methods, and computer-readable storage media for video and secondary audio source synchronization. A system practicing the method establishes a communication with a device such as a telephone or digital device and receives an identification of an audio stream associated with a video presentation specified by a user. The user interacts with the system using the dial pad on a telephone or by manipulating controls within a dedicated application on a smartphone or tablet device. The system computes a likely delay affecting most devices receiving the audio stream and delays a transmission of the audio stream to the device by the delay amount. In one embodiment, the system receives a delay adjustment signal from the device and adjusts the delay amount according to the signal. Then the system transmits the audio stream to the device by the new delay amount.

  • Publication number: 20150062353
    Abstract: Techniques are described for inserting encoded markers into encoded audio-video content. For example, encoded audio-video content can be received and corresponding encoded audio and video markers can be inserted. The encoded audio and video markers can be inserted without changing the overall duration of the encoded audio and video streams and without changing most or all of the properties of the encoded audio and video streams. Corresponding encoded audio and video markers can be inserted at multiple locations (e.g., sync locations) in the encoded audio and video streams. Audio-video synchronization testing can be performed using encoded audio-video content with inserted encoded audio-video markers.

  • Publication number: 20150042880
    Abstract: An invention for measuring, maintaining and correcting synchronization between signals which suffer varying relative delays during transmission and/or storage is shown. The present invention teaches measuring the relative delay between a plurality of signals which have suffered differing delays due to transmission, storage or other processing. The preferred embodiment of the invention includes the use of a marker which is generated in response to a second signal and combined with a first signal in a manner which ensures that the marker will not be lost in the expected processing of the first signal. Subsequently a first delayed marker is generated in response to the marker associated with or recovered from the first signal, and a second delayed marker is generated from the second signal. The first delayed marker and second delayed marker are compared to determine a measure of the relative timing or delay between said first signal and said second signal at said subsequent time.
