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.

說(shuō)明書

FIG. 4 is a flowchart illustrating an example process to provide intelligent encoder tuning based on QoE feedback. This example process 400 begins at stage 410, when an encoder receives A/V content from an audio/video source. A/V content can be sent, for example, by an A/V source (e.g., A/V source 110 of FIG. 1 and 210 of FIG. 2 and 305 of FIG. 3) to an encoder (e.g., encoder 120 of FIG. 1 and 220 of FIG. 2 and 310 of FIG. 3). In some implementations, example formats of A/V content can include formats such as, for example, HdMp2, SdMp2, or HdMp4, among many others. In some implementations, the A/V source can be a video server. In other implementations, the A/V source can be an antenna or cell tower. It should be understood that various hardware and/of software platforms can serve to provide the A/V source.
