Initial bitrate selection for video delivery sessions

A bit rate and video technology, applied in the field of video transmission, can solve the problems of wasting traffic and energy, affecting QoE, and increasing the energy consumption of user equipment or equipment in waiting time, so as to prolong the traffic and energy, and improve the effect of QoE.

AI Technical Summary

Problems solved by technology

The initial buffer duration is highly correlated with the user's initial waiting time, thereby affecting QoE
The increase in latency also increases the energy consumption of the user equipment or equipment
In addition, non-optimal initial bit rate selection will cause retransmission of the same video content at different bit rate levels, causing traffic and energy waste on the network

Embodiment Construction

[0038] Throughout the drawings, the same reference numerals are used for similar or corresponding elements.

[0039] This embodiment relates generally to video delivery, and in particular to selection of an initial bit rate for a video delivery session. According to an embodiment, a suitable selection of the initial bitrate of a video transfer session, especially a video streaming session, can solve the disadvantages of the prior art, where the initial bitrate is usually set randomly or towards a high bitrate. For example, an initial bit rate selected according to an embodiment may improve QoE by reducing latency and join time. This is possible because embodiments significantly reduce the risk of performing down bitrate switching and video packet retransmission due to using an initial bitrate that the network cannot handle. This also means that embodiments can reduce the amount of wasted video packets by reducing the risk of retransmitting video packets of video content at anot...

Abstract

Performed by the user device (5, 200) during a time window from launching a video player application in the user device (5, 200) until the video content is selected Network measurements of current conditions to select an initial bit rate for a video delivery session. A respective initial buffering duration is provided for each bit rate available for the video content, wherein the respective initial buffering durations are predicted based on at least one network metric derived from network measurements. An initial bit rate for delivering the video content over the network to the user device is selected based on the corresponding initial buffering duration.

Description

technical field [0001] This embodiment relates generally to video delivery, and in particular to selection of an initial bit rate for a video delivery session. Background technique [0002] Quality of Experience (QoE) of video delivery applications (eg, video streaming applications) has become quite critical to the revenue of service providers because competition among service providers is intense. This incentivizes service providers to provide high-quality services in order to keep existing customers engaged and increase subscriber numbers. The QoE of mobile video streaming is greatly affected by the network conditions of the user equipment and the device running the video service. The change in perceived video quality is largely affected by the change in quality of the mobile network link. [0003] In the context of video streaming, it is known that the join time (ie, the time it takes from the time the user initiates the video to the start of the video), and the playbac...
