  • Patent number: 11449092
    Abstract: An electronic display device includes measurement sensors that measure respective items, a digital display that displays the items, and a processor. The processor determines a main image related to a measurement of at least one of the items and updates a screen at first timing. Upon displaying the main image related to a measurement of an item other than the first item on the digital display, the processor determines that a sub image is related to measurement of the first item, synchronizes the first timing with update timing that is related to the main image, and simultaneously updates the main image and the sub image.

  • Patent number: 10652292
    Abstract: Systems and methods are described to enable synchronized encoding of streaming audio or video content between multiple encoders, in a manner that provides for seamlessly interchangeable encodings. A first encoding begins encoding streaming content at a first point in time, and at a later point in time, a second encoder is configured to begin encoding the streaming content in a manner synchronized with the first encoder. The second encoder communicates via a synchronization protocol with the first encoder, and receives state information of the first encoder, such as a timecode of the streaming content at which the first encoder began encoding. The second encoder uses the received state information to determine a difference in encoding start times between the first and second encoder, and to adjust its timestamp values to match those of the first encoder. Thereafter, the first and second encoders can encode content in a synchronized manner.

  • 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.

    Abstract: A synchronization mechanism embeds synchronization triggers into a television signal or stream at regular intervals. The triggers include an accurate representation of the time in which the triggers were embedded. A receiving device decodes the triggers and synchronizes its internal timer based on the triggers. In this regard, the receiving device obtains a reference time from the internal timer and computes an offset between the reference time and the trigger time. The computed offset is then applied to the reference time. With the receipt of each new trigger, the application compares the trigger time to a new reference time with the most recently computed offset value applied. If there is any variance between these two values, the application creates a new smoothed offset.

In accordance with one embodiment of the present invention, the technique allows a DTV receiver to perform a scan of only those channels that are known to be available within a local terrestrial broadcast region. In accordance with another embodiment of the present invention, the technique allows a DTV receiver that operates in conjunction with an antenna, such as a smart antenna designed to comply with EIA/CEA 909, to use the same antenna configuration parameters for different terrestrial broadcast signals in an instance where such signals are known to originate from the same antenna location.

  • Patent number: 8199253
    Abstract: A clock range setting device including a horizontal counter, a filter unit, a clock detecting unit, a first infinite impulse filter (IIR filter), and a clock range modulator is provided. The horizontal counter counts a horizontal counter value. The filter unit obtains a lead clock of each teletext video signal according to a lead clock range, and generates a corresponding clock intermediate value. The clock detecting unit detects level changes of the lead clock of each teletext video signal according to the clock intermediate value, so as to generate a corresponding current clock cycle number. The first IIR filter generates corresponding number mean value according to the current clock cycle numbers sequentially received by the first IIR filter. The clock range modulator sets the lead clock range corresponding to each teletext video signal according to the current clock cycle number, the number mean value, and the horizontal counter value.

  • Publication number: 20120002103
    Abstract: A system implementing a method for multi-band wireless communication packetizes a block of source video information into a first packet, and packetizes the block of source video information into a second packet corresponding to the first packet, wherein the first packet and the second packet include corresponding video information. The first packet and the second packet are transmitted from a transmitting multi-band wireless station comprising a first radio for communication over a first wireless band, and a second radio for communication over a second wireless band. The first packet is transmitted over the first wireless band and the second packet is transmitted over the second wireless band. The first wireless band operates at a higher transmission rate than the second wireless band. A multi-band receiving wireless station reconstructs the source video based on packets arriving on different bands.

  • Publication number: 20110285905
    Abstract: To aim to provide a video output device that is capable of output a plurality of video streams with use of shutter glasses, and is capable of dynamically switching between different videos such that in the case where a plurality of viewers are viewing a video output by the video output device, only a viewer who is operating a remote control can view a video stream different from a video stream other viewers are viewing. Operation signals each instructing to start or terminate an operation mode are received. In an operation mode, time-sharing output of a first video stream and a second video stream is performed, and synchronizing signals each in synchronization with a time-sharing timing are transmitted. In a normal mode, images that are each generated based on any of images constituting the first video stream are output, and images constituting the second video stream are not output.

  • Patent number: 8010986
    Abstract: A synchronization mechanism embeds synchronization triggers into a television signal or stream at regular intervals. The triggers include an accurate representation of the time in which the triggers were embedded. A receiving device decodes the triggers and synchronizes its internal timer based on the triggers. In this regard, the receiving device obtains a reference time from the internal timer and computes an offset between the reference time and the trigger time. The computed offset is then applied to the reference time. With the receipt of each new trigger, the application compares the trigger time to a new reference time with the most recently computed offset value applied. If there is any variance between these two values, the application creates a new smoothed offset.

    Abstract: Disclosed herein are systems, computer-implemented methods, and tangible computer-readable storage media for captioning a media presentation. The method includes receiving automatic speech recognition (ASR) output from a media presentation and a transcription of the media presentation. The method includes selecting via a processor a pair of anchor words in the media presentation based on the ASR output and transcription and generating captions by aligning the transcription with the ASR output between the selected pair of anchor words. The transcription can be human-generated. Selecting pairs of anchor words can be based on a similarity threshold between the ASR output and the transcription. In one variation, commonly used words on a stop list are ineligible as anchor words. The method includes outputting the media presentation with the generated captions. The presentation can be a recording of a live event.
