20150281709 | SCALABLE VIDEO ENCODING RATE ADAPTATION BASED ON PERCEIVED QUALITY - 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. | 10-01-2015 |

20160050246 | QUALITY-AWARE RATE ADAPTATION TECHNIQUES FOR DASH STREAMING - A quality-aware rate adaptation algorithm is described to optimize the quality of experience (QoE) for a DASH client. Requesting media at a bitrate higher than the available network bandwidth can lead to re-buffering events that disrupt user experience, while requesting media at lower bitrates may lead to sub-optimum streaming quality. The quality-aware algorithm tries to optimize the QoE of a DASH client by maintaining a better trade-off between buffer levels and quality fluctuations. | 02-18-2016 |
20160112707 | POLICY-BASED IMAGE ENCODING - Techniques for image rendering are described herein. The techniques may include providing image data to an encoder for transmission to a display. An indication of whether at least a portion of the image data is video data or non-video data is provided. A first policy may be implemented for image data that is video data. The first policy prioritizes transmission of the image data over encoding image quality. A second policy may be implemented for image data that is non-video data. The second policy prioritizes encoded image quality over transmission of the encoded images. | 04-21-2016 |
