Several techniques aimed at reducing computational complexity when encoding uses bi-predictively encoded frames (B-frames) are implemented in a video encoder. In an embodiment, B-frames are not used as reference frames for encoding P-frames and other B-frames.

In another embodiment, cost functions used in motion estimation for B-frames are simplified to reduce computational complexity. In one more embodiment, fractional pixel refinement in motion search for B-frames is simplified. In yet another embodiment, predictors used in motion estimation for a macro-block in a P-frame are selected from a B-frame that uses a same reference frame as the P-frame. |

Decoder for playing big frames
The decode time of big frames may be reduced by starting big frame decoding much earlier than normal decoding order. In a multi-threaded decoder, decoding one frame can be divided into several stages and stages of different frames can run in parallel like a pipeline. The first stage may be the token parser which is the most time consuming among all the stages because it is sensitive to bitstream size. If one or more stages of big frame decoding can be done much earlier than normal decoding order, the decode time spent exclusively on the big frame (not including the time shared with other frame decoding) may be much less in some embodiments. In this way, big frame decoding time may be reduced and in addition, depending on how big the big frame is, the decoder control can control how early to start decoding, so that frame drops caused by big frames can be reduced or eliminated. |

In some embodiments, the operation is a stream cipher, and the engine generates a sequence of keystream blocks and performs a combining operation between the input block and a keystream block having a corresponding sequence position. In other embodiments, the cipher operation is a block cipher, and the engine generates, but doesn't output, blocks of data that encrypt, or decrypt, one or more blocks preceding the received input block. |

Error detection and correction by modulation quality in 5G/6G
Message failures due to noise and interference cause unnecessary delays and reduction in reliability in wireless networks. To detect, localize, and correct transmission faults in 5G and 6G networks, the receiver can measure the “modulation quality” of each message reference element, according to how closely the amplitude and phase match the amplitude and phase levels of the modulation scheme. If the message is faulted, the receiver can re-assign each message element with poor modulation quality to the adjacent states, or if necessary to each state in the modulation scheme, and may thereby find the correct message value in many cases. Certain zones around each modulation state can indicate how the message element has been distorted by interference, and thereby indicate where to search for the correct state of that message element. When implemented, message fault mitigation as disclosed herein can resolve message failures, improve communication reliability, reduce latency, and improve network operations overall, according to some embodiments. |

Electromechanically damped resonator devices and methods
Micro-machined acoustic and ultrasonic transducer (MAUT), particularly piezoelectric MAUT (PMAUT), performance tradeoffs have meant reasonable pixel depth resolution necessitated low quality factor (Q) transducers with power distributed over a large bandwidth yielding modest imaging ranges whilst high-Q transducers providing higher acoustic power output for longer imaging ranges exhibit extended ringing limiting pixel depth information. Accordingly, the inventors have established MAUTs supporting high-Q transducers for long-range high-resolution imaging by integrating electromechanical actuators (dampers) which can be selectively engaged to mechanically damped the MAUT. In several applications PMAUT arrays are required where all transducer elements should have almost identical resonant frequencies. However, prior art fabrication processes have tended to produce PMAUTs with large inter-chip and inter-wafer variances. Prior art methodologies to reduce inter-wafer process variations do not address intra-wafer or inter-chip process variations and accordingly the inventors have established manufacturing methodologies and design solutions to address these for the PMAUT resonant frequency. |
