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.

說明書

FIG. 3 is a sequence diagram illustrating an example method operable to provide intelligent encoder tuning based on QoE feedback. The sequence diagram 300 can involve one or more audio/video source 305 (e.g., audio/video source 110 of FIG. 1 and 210 of FIG. 2) interactions with an encoder 310 (e.g., encoder 120 of FIG. 1 and 220 of FIG. 2), intelligent monitor 315 (e.g. intelligent monitor 150 of FIG. 1 and 250 of FIG. 2), and quality analyzer 320 (e.g. quality analyzer 160 of FIG. 1 and 260 of FIG. 2). In some implementations, the intelligent monitor 315 can reside in the encoder 310 or can be placed in another networked device external to the encoder 310. In additional implementations, the quality analyzer 320 can reside at the user's premise or placed in the network in another device.

The flow to provide intelligent encoder tuning based on QoE feedback can begin when an audio/video source 305 sends raw A/V to the encoder 310 (325). Example formats of raw audio/video can include formats such as, for example, HdMp2, SdMp2, or HdMp4, among many others. In some implementations, the audio/video source 305 can be a video server. In other implementations, the audio/video source 305 can be an antenna or cell tower. It should be understood that various hardware and/of software platforms can serve to provide the audio/video source 305.
