  • Patent number: 10264353
    Abstract: Several first digital streams of first digital samples at a first sampling frequency are processed to issue corresponding stream that are converted into second digital streams sampled at a second sampling frequency lower than said first sampling frequency. At least one delay to be applied to at least one first digital stream to satisfy a condition on the second digital streams is determined and applied to at least one first digital stream before converting. The converting operation performed is decimation filtering of the first digital streams. The application of the at least one delay to at least one first steam involves skipping a number of first digital samples in the at least one first digital stream. The number skipped depends on the value of the at least one delay. Samples that are skipped are not delivered for decimation filtering.

  • Patent number: 10019971
    Abstract: The disclosed embodiments provide a system that facilitates driving a display in a computer system. During operation, the system receives an input video stream from a graphics source, wherein the input video stream comprises a sequence of video frames. Next, the system directs the input video stream through a set of two or more memory buffers including a front buffer and a back buffer to produce an output video stream, which is used to drive the display. While directing the input video stream through the set of memory buffers, the system writes a video frame from the input video stream into the back buffer, and concurrently drives the output video stream from a preceding video frame in the front buffer. When the writing of the video frame completes, the system switches buffers so that the back buffer becomes the front buffer, which drives the output video stream, and the front buffer becomes either a spare buffer or the back buffer, which receives a subsequent frame from the input video stream.

    Abstract: Methods, systems, and devices are described for media synchronization. Multi-stream media processes may include media streams captured with respect to different clock rates. Multi-processor implementations may involve separate clocks associated with different media streams, such as audio and video, respectively. The separate clocks may tend to drift from one another, becoming further out of sync as time passes. Selecting a reference time of one of the processors to function as a “wall clock,” recording frame capture times with respect to the reference time, accounting for propagation delays, and transmitting frame capture times in terms of the reference time may aid in AV synchronization at a device where audio and video streams are received.

  • Patent number: 8964119
    Abstract: Methods and apparatuses are provided for transmitting and receiving multimedia contents that include at least two components (C1, C2). The reception method entails the reception of a first component (C1) from a first transmission medium (DVB) and the reception of a second component (C2) from a second transmission medium (IP), as well as the steps of: detecting (A4) a first “watermark” sequence from the first component (C1), detecting (A4) a second “watermark” sequence from the second component (C2), synchronizing (A5) the first and second components (C1, C2) on the basis of the first and second “watermark” sequences, and combining (A6) the synchronized first and second components (C1, C2) to form the multimedia content (MM); of course, the reception method provides the desired results if both components have been suitably and repeatedly marked prior to transmission.

  • Publication number: 20150049248
    Abstract: Methods, systems, and devices are described for media synchronization. Multi-stream media processes may include media streams captured with respect to different clock rates. Multi-processor implementations may involve separate clocks associated with different media streams, such as audio and video, respectively. The separate clocks may tend to drift from one another, becoming further out of sync as time passes. Selecting a reference time of one of the processors to function as a “wall clock,” recording frame capture times with respect to the reference time, accounting for propagation delays, and transmitting frame capture times in terms of the reference time may aid in AV synchronization at a device where audio and video streams are received.

  • Patent number: 8934056
    Abstract: An audio-video synchronization detection device and a method thereof are provided. The audio-video synchronization detection device detects an object under test which is capable of generating an image signal and an audio signal. The audio-video synchronization detection device includes a delay circuit, an optical sensor, and a signal processor. The delay circuit delays the audio signal for a predetermined time and generates an audio correction signal accordingly. The optical sensor senses a light emitted by a display panel when the display panel displays the image signal and generates an image sensing signal accordingly. The signal processor calculates a delay time between the audio correction signal and the image sensing signal to obtain a synchronization state between the image signal and the audio signal.
