Requirement | Description |
Playback on various platforms | Students may need to watch videos on different platforms and devices. |
Smart subtitling | Subtitles help students at different levels better understand the teachers, who may speak with different speeds and accents. Class videos are often long, and manual subtitling can be time-consuming. |
Copyright protection | Educational platforms often need to rent dedicated sites, purchase professional equipment, and hire teachers to produce educational content. This content can be costly to produce and is a valuable digital asset. Therefore, educational platforms need copyright protection schemes to protect their content from piracy. |
Time shifting | Students entering ongoing classes may need to watch content from an earlier time point. |
Psuedo-live streaming | Platforms need to be able to live stream pre-recorded courses at the scheduled time. Compared with offering content on demand, students usually pay better attention when watching a live stream. Psuedo-live streaming also helps platforms cut costs (for renting sites, buying equipment, and hiring teachers) and reduce risks (because they can moderate the content in advance). |
Content moderation | Educational platforms need to moderate their content to prevent inappropriate content from having a bad influence on students and bringing them legal risks and negative publicity. Most class videos are long. Human moderators are inefficient and may miss content. |
Media blocking | Because online courses are mostly watched by minors, platforms need to pay special attention not to expose them to inappropriate content. For non-compliant video segments that incorrectly passed moderation, platforms need to be able to quickly block them. |
Cost reduction | Students need high video quality and smooth playback for effective online learning. This means high storage costs for platforms. |
Requirement | Recommended VOD Feature |
Playback on various platforms | VOD can convert one video source to streams of different bitrates to meet playback requirements under different network conditions. VOD offers a player SDK that comes in editions for different platforms including iOS, Android, web (Flash/HTML5), and Flutter, allowing you to distribute high quality videos to different devices. The player can collect statistics on playback performance. |
Smart subtitling | VOD can quickly and accurately recognize speech and generate subtitles in standard formats. |
Copyright Protection | VOD offers hotlink protection schemes based on referer and key. VOD supports HLS private encryption and commercial-grade DRM schemes to protect your content from piracy. |
Time shifting | Students can watch content from an earlier time point during a live streamed class and can switch back to live at any time. |
Psuedo-live streaming | Psuedo-live streaming allows you to stream better planned and more condensed content. It also helps you reduce costs. |
Content moderation | VOD can automatically recognize non-compliant content in courses to help you offer a healthy learning experience and reduce risks. |
Media blocking | This feature allows you to quickly block videos when non-compliant content is detected. |
Cost reduction | For infrequently accessed videos, you can save only a low-definition version and delete the high-definition versions to reduce your storage costs. You can also specify expiration time for videos so that expired videos can be automatically deleted. To reduce storage costs, you can configure smart cold storage policies to downgrade the storage class of files based on their creation time, category, and playback count. |
