In our previous article, Reako Xie, founder of POLYV, showed us his creative perspective on online education and e-commerce, and made a comparison between them.
Here we deliver the second part of his speech, focusing the major issues of the video application in e-learning and online education.
Video is getting more and more important in nowadays internet technology. It is also the skeleton of the online education industry, influencing the process of teaching and learning.
Video has great advantages like containing massive information, well intuitive and interactive, which is unparalleled to texts and graphics. However, video needs a great amount of time for production and takes up lots of space and traffic for hosting, which is an obstacle for wide commercial use.
Here are the three major issues we have encountered –
First, piracy. It grows easily because videos are highly replicable, and the cost is legitimately low without effective copyright control.
Here we take the example of music records. It is a great industry over the 20th century, generating thousands of superstars and celebrities as well as tremendous value. However, at the beginning of the 21st century, music piracy has breached the industry thanks to the develop of the internet and the technology of audio compression in the cloud. That’s when music piracy becomes very simple that everyone can do this, and eventually the industry goes downhill.
As far as I concern in this case, I think it is just not enough to expect the fulfilment of the law, or everyone has the sense of copyrighting. We must take action and protect the video content from piracy.
As we all know, videos, presentations and other materials are the core resources for online educators and e-learning organizations. Once the resources are leaked and being sold at a really low price, it will devastate the whole online education industry.
To prevent this, POLYV releases the first generation of DRM (Digital Rights Management). Most of the 4000 primary users at that time subscribe our plan because of the DRM feature. And, after the development of over 3 years, the DRM prototype has evolved into PlaySafe DRM ecosystem, including fragmentation encryption on all kinds of content, anti-downloading, domain lists, anti-capturing and more. We will release new piracy proof system later this year, to protect the content from our users in full scope.
No system is absolutely safe, but we believe piracy can be inhibited by increasing the cost of obtaining the content illegally and compromising the experience of pirated content.
Second, the video content is non-structured. In other words, the content, plot or details in the video are unable to be indexed or searched, nor to be accurately positioned for a specific chapter or key point, making it inefficient to obtain our desired content.
To solve this issue, we develop an audio recognition system, which can accurately recognize different voice by learning, build up an index of the video and generate captions or subtitles automatically, which really help with the indexing and searching of the content.
Besides, the audio recognition system can sort the key points of the videos, identify the courses from different teachers and classify them by author, topics or length, you name it. All the actions are processed automatically without manual intervention, even if there are millions of videos. Only when sorted do data become knowledge, and that is the foundation of digital content management.
Third, immersive learning. Currently, this is one of the major difference between online education and traditional learning, and VR is a possible and potential way to solve it.
We made lots of experiments and exploration on VR (Virtual Reality), and some of the VR products have been released. We have introduced our VR devices in May this year and will release VR app in December. Our VR live streaming has been applied for online education, which is affordable and cost efficient in both software and hardware.
For now, we are developing an app for external video live streaming, which will be released at the end of this year, and will support Oculus and Microsoft Hololens in the future. We hope that POLYV will become a connection between videos and VR, and aid live streaming for online education.
We believe that with the popularity of VR, it will be the turning point for online education.
That’s all for my speech. Thank you all very much.
