Abstract: Multi-layered video structures are scaled over a range of perceived quality levels. An estimated Mean Opinion Score (eMOS)-based encoder control loop is utilized to determine one or more encoder key performance index (KPI) associated with a particular perceived quality level. A KPI-based encoder control loop is then utilized to guide generation of a hierarchical structure having quality and/or temporal and/or spatial enhancement layers, without recalculating eMOS for the scalable structure. In addition, eMOS is used to guide the generation of a hierarchical structure at best-perceived quality levels for a given bitrate budget. Rate adaptation may occur by dropping segments, changing hierarchical structure, or changing the KPI target values. With the structure scaled as a function of perceived quality, perceived quality is impacted predictably as the encoding rate is adapted.

Abstract: A system and method are provided for using location services available from other radios in a multi-radio system to assist a beamforming mechanism, particularly in establishing and maintaining mmWave communication link. A majority of wireless client devices for use in a mmWave communication link are equipped with multiple radios. Many of the “other” radios include technologies that support location based services, including GPS, Wi-Fi and cellular communications. One or more non-mmWave in one device is used to provide relative location information regarding the other device with which the mmWave communication link is to be established. The relative location information is used to derive a direction for communication, and to compute beamforming parameters, in a limited set of transmit/receive sectors where the destination device is likely to be found, in order to streamline the beamforming process.
