基于RTMP的在線互動視頻教育云平臺的設計與實現(xiàn)
[Abstract]:In recent years, Internet and smart phone have been popularized rapidly, 4G technology has been developed and popularized rapidly, the network environment has been improved unprecedentedly, and the traditional offline education model has been restricted by traditional factors, and it is also facing the challenge of soaring rent and labor costs. At the same time, the individualized needs of the educatees also lead to the gradual transformation of teaching mode to small classes and VIP elite courses, and the online education on the Internet presents a vigorous development trend. Foreign major Internet education platforms or products or access to financing, domestic online education is also blooming. Throughout the present system, the main teaching form is the students' replay according to the demand after the resources are input in advance, the teaching is more than enough, but the interaction is insufficient, and the product is homogenized seriously. How to innovate the online education system with high fluency, low delay, strong interaction and more suitable for the current network environment and customer needs has become a hot issue. This paper studies and develops an efficient and stable online interactive video education platform system. By studying the transmission mode and transmission protocol of online interactive video, this paper deeply analyzes how to use and optimize the RTMP video transmission protocol to realize the transmission and playback of online interactive video. In this paper, the RTMP protocol data is divided into blocks, the traditional data blocks are subdivided into data units, and the queue management data temporary sorting and sending means are used to transform single-line transmission into multi-line transmission. It improves the utilization rate of network channel, reduces the delay of online users to watch live broadcast, and improves the fluency. At the same time, the existing cloud technology is analyzed, aiming at the overall implementation of the system, the mainstream architecture of the current software implementation and advanced front-end technology are investigated and selected. In this paper, we propose a cloud deployment scheme based on VMware vSphere, which makes full use of cloud computing and processing capabilities, and solves the problems of slow data computing delay and low push efficiency in online video education platform. The test results show that the online interactive video education platform deployed through the RTMP protocol and cloud platform can achieve multi-user, efficient and stable online video interactive effect, at the same time, compared with other live broadcast websites, the online interactive video education platform can handle concurrency. There are obvious advantages in online video fluency, such as resource consumption, traffic and so on.
