PARTNER FEATURE: 5G networks have the characteristics of high speed, large capacity, low latency and low energy consumption, which will lead to great changes in all industries of the society, especially the video industry. As a mature 5G application scenario, video will embrace more promising prospects in the future. With 5G networks, high-quality video content such as UHD, 4K, 8K, and 120-frame videos will become popular for consumers, and VR, AR, interactive video, and AI-based video content will be their next hot videos. Paid video content will also change in intelligent distribution mode such as advertising, and the use of big data and AI can make video content target the right audience, which will improve video revenues.
5G Video Features
5G networks provide more development opportunities for the video industry. Continuous technical explorations have been made in the fields of high-quality video experience (4K, 8K, and VR), diverse video services (long videos such as movies and TV series, social videos, and live webcast), content security (storage, transmission, and copyright), video user profile and operation, and CDN (MEC-CDN, P2P-CDN, VCDN, and MESH-CDN). Cutting-edge technologies such as cloud VR, virtual set-top box (vSTB), MEC CDN, and automatic multicast tunneling (AMT) are also constantly being explored and innovated.
The consumption scenario of 4K UHD content involves content provider (CP), service provider (SP), and content consumption (CC), which belongs to a complex many-to-many scenario. Therefore, 4K copyright content requires an end-to-end digital copyright protection system that takes into consideration the interests of all parties. To meet the requirements of future network copyright protection, the new-generation DRM requires unified content encryption implemented at the front end and unified content encryption pre-deployment supported at the terminal side.
5G Video Innovations
The existing VR will coexist for a long time with 5G VR. Existing VR users, especially professional ones, need local rendering and control, which poses higher requirements on VR devices but delivers an ordinary user experience. However, in the 5G Cloud VR mode, the data is transmitted to the cloud through a 5G network, and then the processed data is sent to a VR headset. In this process, the VR headset becomes a terminal that receives and sends signals and displays content. It only needs little edge computing capability to drive the operation of the entire system. With less power consumed as a result of lower requirement for chip performance, the VR headset will have a better battery life. Moreover, the 5G network has a more powerful geo-location ability, which also improves VR user experience to a certain extent.
By using AI and other application capabilities deployed on the MEC cloud platform, videos can be analyzed and processed to offer value-added services such as scene capture and action recognition. In a traditional large sporting event, on-site spectators cannot see the details of the game due to the restrictions of viewing distance and seat position. However, with the 5G Live TV solution, spectators can use their smartphones to make the cameras lock on a certain player or a specific angle, zoom in or out views on the screen to see the details, and can also rotate views 360 degrees to enjoy a personalized game-watching experience.
5G technologies will upgrade short video experience and expand its application scenarios. Download HD and upload bandwidth guarantee all greatly improve the quality of short videos. Besides the basic content, 5G will also penetrate into application scenarios such as video social networking service (SNS) and distance education.
The most extensive applications of AI in short videos are personalized recommendation and targeted advertising, which makes full use of data and value brought by users. With the continuous development, AI has also made achievements in assisting users in content production and smart operation. Smart covers and subtitles, real-time beautifying and reshaping, and even face exchange and action generation all appear in the creation of short videos.
The number of short video users in China reached 249 million in 2019. In the 5G era, the biggest traffic problem in video SNS will be solved. SNS is the most fundamental value in the video era. It is expected to build a user-centered SNS to promote in-depth social interaction and the boom in short video SNS. In the e-commerce field, short video has also shown its product selling capability, highlighting its future business value.
There are three types of interactive videos: customizable, conversational, and exploratory. The exploratory interactive video is relatively new and generally provides few tips or even no tips, allowing users to explore interactive points and ways in the video. This type of videos usually adopts real-life scenes to make viewers feel more immersive. Before a user operates, the video is played in a cyclic manner until the user finds the interactive point.
In China, there are more than 700 million online video users, and the number of consumers who are willing to pay for video services is still growing. As 5G networks are widely deployed, viewers will pose higher requirements on online videos. In the future, more and more breakthroughs and innovations will be achieved for online videos, which involve improving video quality, providing a clearer, faster and more diversified audio-visual enjoyment, and bringing a new experience to users in the fields of 4K, 8K, VR, holography and short video.
