BEIJING, March 16, 2020 /PRNewswire/ -- Recently,
iQIYI, Inc. (NASDAQ: IQ) ("iQIYI" or the "Company"), an innovative
market-leading online entertainment service in China, together with Peking University and
Microsoft Research, jointly published a paper on EPASS360, a
newly-developed panoramic video streaming media system based on AI
technology, titled EPASS360: QoE-aware 360-degree Video
Streaming over Mobile Devices (the "Paper"). The Paper
was accepted by IEEE Transactions on Mobile Computing (TMC), a top
international journal in the field of Mobile Computing. Under
current home broadband and WiFi environments, this new system
solution will predict the allocation rate according to the user's
visual field to ensure that the user sees a clear and smooth
picture when watching panoramic videos.
360-degree VR panoramic videos are designed to give users a
truly immersive video-viewing experience, and to achieve that, it
should be set in either ultra-high-definition modes such as
8K or 16K. Network transmission speed of current home
broadbands or WiFi, however, does not meet the transmission
requirements of ultra-high-definition videos, meaning that users
are unable to have the high-quality panoramic video experience at
home.
The EPASS360 system can carry out targeted code rate
optimization according to different user experience objectives
combined with accurate recognition and prediction of playback
process. According to iQIYI daily data collected by the academic
and public data sets on the experimental results show that EPASS360
is able to increase image quality by about 50% (measured in PSNR,
peak noise ratio for the meter) compared to a normal panoramic
video streaming media system. The EPSS360 is also at least 5%
higher in final user experience scores compared to leading
panoramic video streaming media systems.
The main purpose of application for the EPASS360 solution of
panoramic video streaming media system is to create the best
viewing experience for users. At present, panoramic videos,
including VR short films that are iQIYI IP-spinoffs, such as those
created for iPARTMENT 5, works performed by the youth
competition segment finalists of Wuzhen Theatre Festival, and the
LANVIN 2020 autumn/winter women's show, have been launched in the
iQIYI VR App, while 360-degree panoramic videos have been made
available on Qiyu VR headset products.
iQIYI has long been carrying out discussion and cooperation with
the academic community, having continuously increased its research
and investment in cutting-edge media streaming technology. The
full-year financial results of iQIYI 2019 showed that the R&D
expenditure of iQIYI in fiscal year 2019 was RMB 2.7 billion, which represented an increase of
34% compared with the same period in 2018. In addition to the
research related to EPASS360, the paper "Improving Quality of
Experience by Adaptive Video Streaming with Super-Resolution",
which was submitted by iQIYI in collaboration with Peking
University and Huazhong University of Science and Technology this
year, has also been accepted by IEEE INFOCOM 2020. iQIYI also
pioneered the real-time evolution system of multiple Adaptive
Bitrate Streaming algorithms (RESA), which increased the average
bitrate of videos watched by users by 20%, while the user streaming
buffering rate decreased by 13%. In 2019, the paper "RESA: A
REAL-TIME EVALUATION SYSTEM FOR ABR" was accepted by IEEE ICME
2019. In the future, iQIYI will continue to strengthen its
cooperation with academic and industry partners, and continue to
create new technical standards and innovative experiences related
to the video industry.
