Receiver Circuitry Patents (Class 348/725)
  • Patent number: 11262975
    Abstract: A soft decision audio decoding system for preserving audio continuity in a digital wireless audio receiver is provided that deduces the likelihood of errors in a received digital signal, based on generated hard bits and soft bits. The soft bits may be utilized by a soft audio decoder to determine whether the digital signal should be decoded or muted. The soft bits may be generated based on a degree of closeness of a detected phase trajectory to known legal phase trajectories determined from the running the phase trajectory through a soft-output Viterbi algorithm. The value of the soft bits may indicate confidence in the strength of the hard bit generation. The soft decision audio decoding system may infer errors and decode perceptually acceptable audio without requiring error detection, as in conventional systems, as well as have low latency and improved granularity.

  • Patent number: 10636176
    Abstract: Textual overlays/labels add contextual information in Augmented Reality (AR) applications. The spatial placement of labels is a challenging task particularly for real time videos. Embodiments of the present disclosure provide systems and methods for optimal placement of contextual information for Augmented Reality (AR) applications to overcome the limitations of occlusion with object/scene of interest through optimally placing labels aiding better interpretation of scene. This is achieved by combining saliency maps computed for each frame of an input video with Euclidean distance between current and previous overall positions for each frame based on an initial overlay position of the label to calculate an updated overlay position for label placement in the video. The placement of overlays is formulated as an objective function that minimizes visual saliency around the object of interest and minimizes the temporal jitter facilitating coherence in real-time AR applications.

  • Patent number: 10511462
    Abstract: Techniques are disclosed relating to DC interference cancelation in received wireless signals. Disclosed techniques may be performed in the digital domain, in conjunction with analog cancelation techniques. In some embodiments, a receiver apparatus operates a local oscillator at a frequency corresponding to a particular pilot symbol in a received wireless signal. In some embodiments the receiver estimates DC interference at the frequency based on the received pilot symbol (this may be facilitated by the fact that the contents of pilot symbols are known, because they are typically used for channel estimation). In some embodiments, the receiver apparatus is configured to cancel the DC interference based on the estimate to determine received data in subsequently received signals at the frequency. Disclosed techniques may allow narrowband receivers to efficiently use more of their allocated frequency bandwidth, rather than wasting bandwidth near the frequency of the local oscillator.

  • Patent number: 10404516
    Abstract: A data demodulation method, apparatus, and system are presented. The method includes obtaining notification information indicating that user equipment (UE) is in a high-speed moving state; performing time-frequency synchronization processing on first downlink data according to the notification information to obtain second downlink data; and performing demodulation processing on the second downlink data to obtain third downlink data, where in the demodulation processing, inter-transmission time intervals (TTIs) filtering for a channel estimation is not performed, or a filtering coefficient as a weight of a current TTI for a channel estimation is greater than a filtering coefficient as a weight of a TTI that is at the time when the UE is in the non-high-speed moving state for a channel estimation. The demodulation method is applicable to a high-speed scenario for improving a downlink data throughput of the UE.

  • Patent number: 10375435
    Abstract: A method for programming a recording of a program by a digital television decoder. The decoder has a service plan including a plurality of services. The program to be recorded is broadcast on a first service. The decoder is aware of the first service, an identifier of the program to be recorded, and a theoretical start time of the program to be recorded. When the decoder receives a first standardized table from the first service, the decoder is put in a first operational mode in which the decoder starts recording the program based on the detection of an identifier of the program in the first standardized table, and, when the decoder detects no reception of the first standardized table, the decoder is put in a second operational mode in which the decoder starts recording the program based on the theoretical start time of the program.

  • Patent number: 10372664
    Abstract: A first communication unit 21 of a host-side transceiver device 20 performs communication based on an I2C communication scheme with a host device 10 and receives an access request signal sent from the host device 10. A second communication unit 22 performs communication based on a communication scheme different from the I2C communication scheme with a remote-side transceiver device 30 and sends the access request signal received by the first communication unit 21 to the remote-side transceiver device 30. The first communication unit 21 notifies the host device 10 that the first communication unit 21 has received the access request signal sent from the host device 10 before the access to the remote device 40 based on the access request signal sent from the second communication unit 22 ends.

  • Patent number: 10291945
    Abstract: The present technology relates to a data processing apparatus and a data processing method that enable correct clock synchronization by use of clock information. The data processing apparatus receives a digital broadcast signal so as to process content included in the digital broadcast signal and clock information also included therein for use in presentation synchronization on the content and sends via a transmission path the processed content and clock information to another data processing apparatus that presents the received content. On the other hand, the another data processing apparatus receives via the transmission path the content and clock information sent from the data processing apparatus so as to process presentation synchronization on the received content on the basis of the received clock information. The present technology is applicable to data processing apparatuses configured to process content, for example.

  • Patent number: 10175418
    Abstract: An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Viewing windows are formed through imaging individual light sources and hence defines the relative positions of system elements and ray paths. The uncorrected system creates non-illuminated void portions when viewed off-axis preventing uniform wide angle 2D illumination modes.
