BEIJING, July 23,
2021 /PRNewswire/ -- iQIYI Inc. (NASDAQ: IQ) ("iQIYI"
or the "Company"), an innovative market-leading online
entertainment service in China, is
pleased to announce that a paper on improving video streaming
quality (the "Paper") the Company co-published with Tsinghua
University was named the Best Paper Award Runner-Up at the
International Symposium on Quality of Service (IWQoS) 2021, which
is jointly hosted by the Institute of Electrical and Electronics
Engineers (IEEE) and the Association for Computing Machinery
(ACM).
Co-authored by iQIYI and the Institute of Trustworthy Networks
and Systems at Tsinghua University (TNS), the Paper,
titled "Understanding and Improving User Engagement in Adaptive
Video Streaming", proposes a quantitative model of user experience
measurement centred on user engagement. Through full validation via
the Adaptive Bitrate Streaming Service (ABS) on iQIYI's Cloud, the
model can help users enjoy a smooth viewing experience for a long
duration and in different scenarios.
IWQoS is a highly prestigious forum where novel ideas on
all QoS-related subjects are presented. The current award marks
another international academic recognition for iQIYI. In
2019, the Company's paper on the development of a real-time
evolution system of multiple Adaptive Bitrate Streaming algorithms
(RESA) on ABS was accepted at the IEEE's International Conference
on Multimedia and Expo (ICME).
Various user scenarios—such as watching a video while riding
public transport—can cause dramatic network churn and a persistent
lag. In order to avoid any diminishment in the viewing experience,
iQIYI and TNS set up a joint research team to enhance the
experience of extended viewing by leveraging iQIYI's on-demand
streaming data and the ABS intelligent bitrate platform on the
cloud.
Deeply committed to improving the streaming experience across
scenarios and devices, iQIYI has long focused on developing
technologies for intelligent bitrate algorithm optimization and lag
reduction. Compared with the control group, iQIYI's current
technology can reduce the time-lag ratio by 15-30%, generating a
25% increase in the percentage of streaming time at a resolution of
1080P or above. As the technology supports a wide array of devices
and scenarios (such as different network types), it provides
customized optimization suggestions on the algorithms for bitrate
adjustment strategies.
With more and more users stream content using their mobile
devices, streaming services must continue to improve streaming
quality across different network environments via solid bitrate
selection algorithms. Grounded in its commitment to build the
world's best video service, iQIYI combines cutting-edge technology
with high-quality content as the Company continues to lead the pack
in delivering the ultimate viewing experience to users.
