摘要

Various methods, systems, and apparatuses can be used to provide intelligent tuning based on quality-of-experience (QoE) feedback. In some implementations, an encoder can be modified to receive QoE feedback and subsequently adjust the transmitted output video signal. For example, based on a QoE feedback, an output compression rate can be optimized. In other implementations, an external intelligent monitor can be used to receive QoE feedback, compute output compression rate adjustments, and send adjustment commands to the encoder. Dynamically adjusting encoder parameters can reduce bandwidth while maintaining a high QoE.

At stage 530, QoE feedback is generated and a QoE score and/or other codes are sent to the intelligent monitor (IM). The QoE feedback can be generated, for example, by the quality analyzer (e.g., quality analyzer 160 of FIG. 1 and 260 of FIG. 2 and 320 of FIG. 3), which can send QoE feedback (or other codes) to the intelligent monitor (e.g., intelligent monitor 150 of FIG. 1 and 250 of FIG. 2 and 315 of FIG. 3). In some implementations, the quality analyzer can be located within the STB/GW/CPE device. In other implementations, the quality analyzer can be located in another networked device. In some implementations, the intelligent monitor can receive the QoE feedback via an SNMP trap. In other implementations, another method such as, for example, a proprietary messaging format or out-of-band (OOB) channel can be used to transfer QoE feedback, among many others. It should be understood that QoE feedback can include an audio and/or video QoE score with associated defect codes that can be used to increase granularity and customization for adjustments to the encoder settings.
