Problems solved by technology

It is precisely because of the decline in the professionalism of broadcast equipment and personnel that the quality of the content provided is poor, and is limited by the upload network speed and server bandwidth pressure, resulting in delays, freezes, frame drops, out-of-sync images and audio, etc. Problem, in order to reduce such situations, the strategy adopted is to reduce the resolution of the video and increase the compression ratio, resulting in small pictures and unclear text, which is not easy to recognize
More importantly, viewing on the mobile Internet is limited by the speed of the 3G / 4G downlink network, which often takes a long time to cache and is easy to disconnect

Embodiment 1

[0027] Such as figure 1As shown, the dynamic interactive lecture system of this embodiment includes a publishing unit, a storage unit and a receiving unit. The publishing unit creates the lecture content, configures the corresponding ID and stores it in the storage unit, and the receiving unit selects the playback content and then interfaces with the storage unit. Request content, the storage unit asynchronously loads the lecture content corresponding to the ID into the cache of the receiving unit, operates according to the audience, the front-end page runs according to the written program, and transmits it to the receiving unit for the audience to receive and watch.

[0028] The publishing unit of this embodiment includes creating a lecture system, and the creating lecture system adopts an instant live broadcast mode, and the instant live broadcast mode includes the following process:

[0029] First, the publisher logs into the terminal software to publish the lecture informa...

Embodiment 2

[0034] Such as figure 2 As shown, the dynamic interactive lecture system of this embodiment includes a publishing unit, a storage unit and a receiving unit. The publishing unit creates the lecture content, configures the corresponding ID and stores it in the storage unit, and the receiving unit selects the playback content and then interfaces with the storage unit. Request content, the storage unit asynchronously loads the lecture content corresponding to the ID into the cache of the receiving unit, operates according to the audience, the front-end page runs according to the written program, and transmits it to the receiving unit for the audience to receive and watch.

[0035] The publishing unit of this embodiment includes creating a lecture system. In this embodiment, creating a lecture system adopts a lecture recording mode, and the lecture recording mode includes the following processes:

[0036] First, the publisher logs in to the terminal software to publish lecture inf...

Abstract

The invention discloses a dynamic interactive lecture system. The system comprises an issuing unit, a storing unit and a receiving unit. The issuing unit establishes lecture contents, configures corresponding IDs and then stores in the storing unit. The receiving unit selects play contents and then requests to the interface of the storing unit for the contents. The storing unit asynchronously loads the lecture contents corresponding to the IDs to the cache of the receiving unit. A front end page is operated according to operations of an audience and compiled programs. The contents are transmitted to the receiving unit, thus carrying out receiving and watching at an audience end. According to the system, breakthrough is carried out from a storing mode; a scene is reproduced through terminal software by matching the time shaft of an operator with the time shaft of audios; the redundant image frames and vector contents are eliminated; the storing data quantity is low; and functions such as follow-up re-edition are realized.

Description

technical field [0001] The invention belongs to the field of the Internet, and in particular relates to a dynamic interactive lecture system. Background technique [0002] After entering the Internet age, offline lectures and conferences have gradually changed from the previous radio and TV live broadcasts to online broadcasts. The transformation of information from point-to-point transmission to multi-point interactive transmission in the Internet PC era relies on the continuous expansion of wired network bandwidth and matures, from 10M to 100M, and is now developing towards Gigabit. However, the Internet has now fully entered the mobile era, and the number of mobile Internet users has far exceeded that of PC users. However, the bandwidth limitation and high traffic charges of mobile Internet access limit the development of multi-point interactive video transmission. Mobile users need to rely on Wi-Fi to Watching, this is against the spirit of the mobile Internet anytime, ...
