Construction of Ultimate Video Experience and Application Innovation System Based on 5G and 8K 5G will make the perfect presentation of 8K UHD and VR, AI, or more innovative applications possible. This paper first introduces the basic attributes of 5G and 8K, then discusses the new era of 5G to open up ultrahighdefinition video applications, and then takes four fields of 8K video content production, VR 8K content production, OTTIPTV content service and AI content service as examples. This paper probes into the innovative application of 5G 8K, and finally puts forward that the media industry should take 5G as the technology engine to layout xe2x80x9c8K ecologyxe2x80x9d to enable the highquality development of technology enabling media industry.

QoEDriven Resource Allocation Optimized for DelaySensitive VR Video Uploading over Cellular Network Uploading Virtual Reality (VR) video over cellular networks is expected to boom in near future, as general consumers could generate highquality VR videos with portable 360degree cameras and are willing to share with others. Consequently, concerns of uplink bandwidth and delay arose for current popular technology of tilebased VR video streaming, which requires high quality video to transcode into multiple representations for further adaptive streaming. Motivated by this, we proposed a novel scheme for uplink delivery of tilebased VR video over cellular network, in which encoding bit rate of each tile is determined by uplink resource allocation (RA), and quality of content (QoC) contribution of each tile and channel quality of user equipments (UEs) are jointly considered during RA. Moreover, the RA problem is formulated as a frequency and time dependent nondeterministic polynomial(NP)hard problem, which can be effectively solved by our proposed approximate convex algorithm. Simulation results show that the proposed algorithm can achieve higher utility, that is higher total quality of experience (QoE) for viewers.
