What are the features of recording, on-demand, and live streaming?
Britannica defines Video on Demand as, “a technology for delivering video content, such as movies and television shows, directly to individual customers for immediate viewing, regardless of broadcast schedules.”
For users, on-demand content is very flexible in time and space. For example, if you buy the column of lessons or series on get, you can arrange your own time to listen or watch to it at any time, which is very flexible, and you can study repeatedly after the class and take notes, which is convenient to digest the learning content.
However, the content of the on-demand is one-way transmission, we passive watch most of the time, real-time interactive elements rather than live a little less.
Video On-Demand (VOD) platforms have been replacing traditional over-the-air television programming in recent years. For instance, YouTube is replacing TV broadcasts and Netflix is replacing movie rental brick-and-mortar stores.These VOD platforms provide users with the freedom to watch, browse and access a range of video topics in a matter of seconds.
A complete set of recording systems includes core functions such as recording and editing, live pushing, class processing, etc., equipped with mature hardware and software. It can produce relatively high-quality video content according to the standard. At the same time, a teacher can operate the whole system by himself, and the user experience is friendly.
However, building such a system requires camera hardware, custom software, video storage transcoding, etc., and also occupies a relatively large space, more labour costs like professional technicians for regular maintenance and overhaul, so the overall cost will be relatively high.
- Live Streaming
Live interaction is two-way, with faster feedback compared to on-demand. Users can interact with the presenter in real time through chat rooms, gifts, pop-ups, and other ways.
Online education is common 1 to 1, small classes, dual-teacher classrooms, all using the teacher-student interaction way of teaching, assistant teachers can observe the learning situation of students, adjust the teaching method, and urge students to complete learning. In this way, the teacher will be able to better grasp the learning effect of students.
However, the current live video has certain requirements for the network, if the user is in the case of an unstable network, the video will be delayed, lagging, affecting the user viewing experience.
Live broadcast of the speaker and content requirements are relatively high, to use a variety of ways to attract users to stay to watch, the occasional live accident also needs the means to deal with. Our global HD video Live streaming solution provide 2100+ CDN nodes to ensure that your live broadcast runs in high-definition without delay, and know more to our Live Streaming Soution.
After learning of recording, on-demand and live streaming, let’s have a small summary.
- Recording hardware and software integration is mature, the output quality is high, but the cost is also relatively expensive.
- On-demand viewing is so flexible that has no limitations by the network, however, the emergence of pop-ups, interactive video to enhance the interactivity.
- Live broadcast enables real-time mutual interaction seamlessly, however, the content of the main speaker has high requirements.
How do video services affect our lives?
The video industry has developed for many years, and every innovation in communication technology has brought a revolution to this industry.
In the 4G era, entertainment live streaming and short videos represented by TikTok and Kwai had endless energy. With the arrival of the 5G era, education, finance, health care, and other fields are on the live express, the boundaries on video applications are expanding and upgrading.
Small interactive classes, dual-teacher classrooms, 1-to-1 instruction and other scenarios will use live video, teachers are able to adjust teaching methods and plans based on real-time feedback from students, and supervise students to complete the task.
After the live broadcast or recording, the video can be directly transferred to on-demand video for permanent playback, and students can use it for review after class.
Consultants and analysts can share their investment experience, interpret policies and provide financial advice to customers through live streaming. There are many banks that also have to give internal training to branches in different regions, and live streaming can save more manpower and material costs.
The advantages of large bandwidth and high stability of 5G network provide technical conditions for remote surgery and consultation. In remote surgery, 4K/8K ultra-high-definition images can be seen in low delay, doctors who has thousands of miles away can be completely “synchronized”, and the accuracy and safety of surgery will be greatly improved.
Taking advantage of the east wind of video technology, TOVP will continue to refine its exploration on this track and contribute its share to the development of the industry.
