Abstract: A video encoding system in which pixel data is decomposed into frequency bands prior to encoding. The frequency bands are organized into blocks that are provided to a block-based encoder that encodes the blocks and passes the encoded blocks to a wireless interface that packetizes the blocks for transmittal over a wireless connection. The encoder may categorize the encoded frequency bands into multiple priority levels, and may tag each frequency block with metadata indicating the frequency band represented in the block, the priority of the frequency band, and timing information. The wireless interface may then transmit or drop packets according to the priority levels of the encoded frequency blocks in the packets and/or according to the timing information of the frequency blocks in the packets.

Abstract: Some embodiments enable secure time of flight (SToF) measurements for wireless communication packets that include secure ranging packets with zero padded random sequence waveforms, including at higher frequency bands (e.g., 60 GHz) and in non-line of sight (NLOS) scenarios. Some embodiments provide a flexible protocol to allow negotiation of one or more security parameters and/or SToF operation parameters. For example, some embodiments employ: phase tracking and signaling to support devices with phase noise constraints to mitigate phase noise at higher frequencies; determining a number of random sequences (RSs) used for SToF to support consistency checks and channel verification; additional rules supporting sub-phases of the SToF operation; and/or determining First Path (FP), Sub-Optimal, and/or Hybrid path AWV modes and the pre-conditioning usage of these modes.

Abstract: Post-amble processing of a beam forming packet may utilize different sector rotation speeds at different wireless communication devices. Power measurements may be captured for individual sectors of an antenna array with respect to a complete rotation of antenna sectors at another wireless communication device. The power measurements may be evaluated to identify a sector for directing a millimeter wave beam between the different wireless communication devices. In some embodiments, a second packet may be transmitted back using the identified sector to determine another sector for directing the millimeter wave beam between the different wireless communication devices.
