Video Industry Trends
Network transmission, computing capabilities, client support, and video experiences continue to benefit from technological advancements, with Huawei's cloud services at the forefront. Having served a total of 565 million network users for video applications in China by June 2017, Huawei continues to refine its proprietary cloud video services, including content production, operations management, and publishing. As the most feasible and resource-effective video content delivery mode, public cloud services provide:
● Lightweight tools for efficient content production, without any investment in professional hardware
● An abundance of intelligent and reliable content management methods with a six-layer protection mechanism to securely host content
● Support for matrix and multi-channel content publishing for multiple device formats
● Content data analysis for personalized recommendations
Business Challenges
Since video streaming involves multiple parties, from live TV sources to the CDN and then to the audience, frame freezing is a possibility during video playback. Here, the key challenge is in improving the video viewing experience by tackling high concurrency in live TV sources, multi-CDN dynamic routing, and unstable streaming to the audience.
Since the live broadcast process involves a series of software and hardware devices, including streaming, network, and video consumption devices as well as live broadcast software codecs, small delays are seen to be acceptable. However, delays that are too large can cause interaction and calling synchronization errors, adversely affecting user experience.
Video leeching is an ethical, legal, and economic issue, as it infringes intellectual property rights and results in extra CDN traffic fees.
The use of high definition and 4K photography devices has further propelled demand for high-quality video viewing experiences, increasing pressure on network traffic and leading to higher traffic fees, often accounting for 3/4 of video broadcast costs.
