  • Publication number: 20260156265
    Abstract: Coding a quantized transform block includes selecting a wavefront scan order for coding quantized transformed coefficients of the quantized transform block. The quantized transform block is of size N×N and the wavefront scan order is such that locations (x, y?1), (x, y?2), and (x, y?3) are sequentially coded and locations (x?1, y), (x?2, y), and (x?3, y) are sequentially coded, for at least one x and one y where 2?x<N and 2?y<N. A probability distribution is selected for coding a quantized transform coefficient of the quantized transform coefficients. A context model for selecting the probability distribution includes at least two immediate neighbors of the quantized transform coefficient in the wavefront scan order. The quantized transformed co-efficient is entropy coded using the probability distribution.

  • Publication number: 20260143125
    Abstract: Entropy coding a sequence of syntax elements using a selective update of a multi-hypothesis probability estimation is described. A sequence of syntax elements is received, where the sequence of syntax elements is associated with a random variable of multiple random variables to be coded. Whether the sequence of syntax elements is entropy coded using a single hypothesis probability model or a multi-hypothesis probability model is determined based on the random variable. Fewer than all multiple random variables are coded using a respective multi-hypothesis probability model. The method also includes determining a symbol for a syntax element of the sequence and entropy coding, using arithmetic coding, the symbol using the single hypothesis probability model or the multi-hypothesis probability model determined based on the random variable. Thereafter, the single hypothesis probability model or the multi-hypothesis probability model determined based on the random variable is updated.

  • Patent number: 12635356
    Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk in a display, a cutting structure may disrupt continuity of the OLED layers. The cutting structure may have two undercuts to disrupt continuity of at least some of the OLED layers. The cutting structure may include a conductive portion that provides a cathode voltage to a cathode layer for the OLED pixels.

  • Patent number: 12621696
    Abstract: For wireless local area network (WLAN) sensing, a non-access point (AP) station (STA) sends a Measurement Setup Query frame to an access point station (AP) to signal one or more preferred time windows of the STA indicating when the STA is available to perform WLAN sensing with the AP. The STA receives a Measurement Setup Request frame received from the AP in response to the Measurement Setup Query frame. The Measurement Setup Request frame may indicate a time-window that is either within one of the preferred time-windows of the STA or a new proposed time-window that is not within one of the preferred time-windows of the STA. The STA may send a Measurement Setup Response frame to the AP to indicate an acceptance when the indicated time-window is within one of the preferred time-windows. The STA may send the Measurement Setup Response frame to indicate a rejection when the indicated time-window is not acceptable to the STA for performing the WLAN sensing procedure.

  • Patent number: 12615543
    Abstract: A non-Access Point Extremely High Throughput Station (non-AP EHT STA) initiates a Quality-of-Service (QoS) setup by sending a Stream Classification Service (SCS) Request frame to an associated access point (AP). The SCS request frame may be encoded to have a request type field set to “Add” and may contain an SCS Descriptor element having a traffic description field, a traffic classification field, and a Multi-Link Operation (MLO) field. The non-AP EHT STA may decode an SCS Response frame from the AP that indicate whether the QoS setup has been added. The non-AP EHT STA may then exchange a QoS traffic flow with the associated AP in accordance with the QoS setup when the QoS setup has been added. When the QoS traffic flow ends, the non-AP EHT STA may encode a second SCS Request frame for transmission to the AP with the request type field set to “Remove” to delete the QoS setup.

  • Publication number: 20260113088
    Abstract: An access point multi-link device (AP MLD) configured for Integrated Millimeter Wave (IMMW) operation may decode a management frame received from a non-AP MLD that advertises a millimeter wave transition delay. The millimeter wave transition delay may be the amount of time for the non-AP MLD to transition from operating in a lower band (i.e., a sub 10 GHz band) to operating in an upper band (i.e., a millimeter wave band). The AP MLD may encode a Basic Beamforming Training (BBT) Announcement frame for transmission to the non-AP MLD in the lower band. The BBT Announcement frame may indicate a start time of a beamforming training phase for performing beamforming training in the upper band. The start time may be no earlier than an end of useful information carried in the BBT Announcement frame plus the millimeter wave transition delay.

  • Patent number: 12610046
    Abstract: Tap-constrained convolutional cross-component model (CCCM) prediction enables hardware coder implementations of CCCM prediction by limiting the number of taps used to predict chroma samples while maintaining accuracy in the prediction. During encoding, a current luma sample of a block is identified. A number of taps to use for predicting a chroma sample associated with the current luma sample is determined based on a size of the block and/or whether the block is downsampled. The chroma sample is predicted using a prediction model limited to the number of taps and then encoded to an encoded bitstream. During decoding, a current luma sample of a block and a number of taps for predicting a chroma sample associated with the current luma sample are decoded from an encoded bitstream. The chroma sample is predicted using a prediction model limited to the number of taps and then output within an output video stream.
