In fact, it is one thing to be recommended by others, and it is another to really try. You know, every online school system is different, and every online education institution is different. You should make a choice according to some characteristics of your own institution. If you are a small organization with limited investment budget, then you should choose a cost-effective and relatively cheap one, such as Bumblebee Cloud Classroom. If you are a company that needs to broadcast live frequently and make a profit from live teaching, then you need to find a company that can broadcast live smoothly without being stuck, so the choice of online school system should be considered according to your actual situation. Really, it's not reliable to rely on people's recommendations. You will know whether it is suitable or not after you have used it yourself. Now many online school systems can be tried out, so you can compare them more. -That's my big truth.
Let's first analyze the tool name, main scenarios, adaptation scenarios, applicable disciplines and advantages.

Complete the closed loop of teaching practice. Cheap price and strong after-sales service team provide operational support for the education industry.
Second, the noun explanation
The charging method of knowledge payment/telemarketing platform: annual payment.
Advantages: the price is low, and there is no upper limit for online concurrent people.
Disadvantages: I really want to do live broadcast services such as large classes and small classes, which is not suitable. This system is not an educational product and does not have the business logic to deal with various educational scenarios. Moreover, regarding live broadcast, it is just a streaming media service, which can't meet all kinds of interactions in the live broadcast scene, such as PPT, lens, multi-dimensional classroom interaction, dynamic courseware and a series of interactive schemes. So it makes sense that their live broadcast is cheap, and the live broadcast is a gift for them.
Real-time SAAS party
Noun interpretation
Make a simple metaphor.
Saas party: provide a set of building blocks. You can buy this set of building blocks back, assemble them at will and turn them into a set of building blocks of your own style, so the SAAS party sells a set of building blocks.
Paas: I sell you the raw material of building materials-wood. After you buy it, you can directly make the wood into what you want.
Charging method: annual charging, concurrent charging/hourly charging.
Noun interpretation
Charge by concurrent number (live online number):
Calculated according to the number of people at the highest concurrent peak within 30 days of the month, multiplied by the unit price, and paid to SAAS service providers.
For example, within a month, the maximum number of people online at the same time is 500 on Monday, 600 on Tuesday and 5000 on Sunday. It is assumed that each concurrency is calculated according to 10 yuan. Then you need to pay 5000* 10 yuan/month =50000 yuan. 1 year: 50,000 * 65438+February = 600,000/year.
Generally, it is signed by year, and the lowest price can be given. If you only need to sign 1-2 months, the unit price will be relatively higher.
If the peak number of part-time workers in that month is less than 5,000, the number of part-time workers of 5,000 will still be calculated. If the number of concurrent employees exceeds 5,000 this month, assuming it is 5,500, the extra 500 employees will be settled separately to SAAS service providers in that month.
Billing by the hour (real-time online time):
The hourly charge is related to the course type/course system.
For example, a small class of 1 right 1 means that 1 teachers and 1 students open wheat at the same time. These two people are equivalent to two roads in the classroom. If a teacher is 1 6, then this teacher and six students are seven roads. The largest number of industries is 1 to 15, which is 16. The number of wheat-opening roads is different, and the hourly charging scheme is also different. For example, two videos may be 1 yuan per hour, multiplied by the number of people, and one hour is 2 yuan, but if it is 1 to 6, the unit price may be 5 yuan per hour, that is, 6 people *5 yuan/hour, that is, 1 hour is 30 yuan.
Before cooperating with saas service providers, be sure to know the daily attendance and number of your students, and then determine whether it is cost-effective to charge by concurrent hours or by hours.
Charging according to the number of concurrency is more suitable for the average number of people per day, without a large number of concurrency differences.
Billing by the hour is more suitable for this multiplayer single-player game scenario. For example, there are only 50 people at ordinary times, and there are 1000 people every day. Suddenly, there is a large class with 1000 people, so it is more cost-effective to charge1000 people by the hour.
Advantages: The system is stable, multifunctional and mature, and various functions can be built according to your own needs.
Disadvantages: independent live broadcast system, no business systems such as course scheduling, attendance, and punching after class.
Live PAAS party
Advantages: The live broadcast tool is at the bottom, with low delay (peak streaming), supporting 1080.60FPS ultra-clear video, flexible and open interface, covering global data centers, and the live broadcast platform and peripheral supporting systems, such as CRM and big data analysis, can be customized, and the data is completely in your own hands.
Disadvantages: Training your own R&D team is expensive. The lowest cost budget of this team should be more than 6,543,800 yuan per year. This is the lowest budget. What we know about the general prices of industries, such as vipkids, is good for our future live broadcast business team, including one-on-one competition. The annual cost should be between 300 W and 600 w.
Online school business system
In addition to the live broadcast service, it is also equipped with a set of business management systems according to various teaching scenarios.
With the knowledge payment platform, their development process is just the opposite. Knowledge payment platform, which is a marketing system. Then I feel that there is a demand for live broadcast in this marketing system, so I have to carry a live broadcast service. The online school business system, whose business development is just the opposite, has a strong ability to develop live broadcast business, but it is found that many institutions are not satisfied with selling a live broadcast system and need to carry some marginal business management systems around the live broadcast system. Therefore, relatively speaking, the team doing online school business system is very professional in live broadcast, which can meet the diversified needs of offline transfer or double-teacher, small class, large class and 1 interaction.
Perfect function and stable system: 100, get scene video and classify it.
Class system application scenario: classin is suitable for small class live broadcast scenario, but not for large class live broadcast teaching; Large class: you can choose from three schools: exhibitor, hundred schools and acquired schools.
Third, analysis and summary.
1. In terms of marketing, it is recommended to choose a knowledge payment platform, such as: micro-praise, praise, goose pass, etc. As a traffic platform, you can cooperate with these brands.
2. Class in small classes.
3. Double-teacher scene and hardware equipment, Baijiayun did a good job.
4. Virtual Hall and Jushi focus on enterprise video conference services.
5. In terms of stability, the interaction between war and history and Baijiayun are the most mature. Of course, this does not include live PAAS, and the stability of PAAS-Tencent and Yinwang is the best, because they provide the lowest-level services.
6. Regarding stability, if the number of concurrent users is less than 200, that is to say, the number of online users in the whole school is less than 200 at the same time, in fact, these SAAS providers mentioned above should have no problem. If there will be more than 500 people online at the same time, or even more than 1000, then the best service providers should be Zhanshi Interactive and Baijiayun, two relatively old companies, with more than 10000 mature people serving as customer cases. Such a service provider is the first choice.
7. In custom development, the most abundant custom interface is to obtain scene video. At present, dual lenses have been introduced. A teacher can have two shots at the same time, broadcast live to users in different positions, which is more suitable for some dance fitness, piano, painting and so on. These offline scenes need to shoot the teacher's face and local movements at the same time.
8 Dynamic Courseware, the most mainstream WEBRTC browser solution in China in recent two years. At present, the best technology in this field is to obtain scene video and blog cloud.
