Description
Technical Field
The invention relates to the technical field of network live broadcast, in particular to a live broadcast method and system with wheat.
Background
A network social platform built on the internet technology gradually forms a live broadcast platform with the microphone along with the technical development, and the live broadcast platform needs to establish real-time information interaction among a main broadcast end, a guest end and a spectator end. Fig. 1 is a schematic diagram of a data transmission architecture in the conventional live broadcast technology. As shown in fig. 1, the server-side live streaming mode and the client-side live streaming mode that use a real-time Network transmission system and a distributed Content Network are included, and a CDN (Content Delivery Network) may be used to synchronously cache information to a CDN Network node close to a viewer for information Delivery of a main-broadcast-side scene, so as to ensure real-time Delivery of information to a large number of viewers. Aiming at the interaction between the anchor and the guest in the anchor scene, a Real-Time network transmission system, such as an SD-RTN (Software-Defined Real Time network) is used for realizing the fast routing and Real-Time transmission of the interaction data between the anchor and the guest, and the Real-Time quality (namely QoS (quality of service) grade) of the interaction is ensured. Usually, the anchor terminal initiates an interaction process with the guest terminal, in the interaction process, interaction information between the anchor terminal and the guest terminal forms information encapsulation through a general audio and video encoder and is sent to the opposite side, the opposite side forms information synthesis through a general audio and video decoder, and an interaction information display scene is formed at the anchor terminal or the guest terminal. The media stream of the anchor end, which shows the scene forming standard, is transmitted to the streaming media server in real time, and the streaming media server is usually arranged in the CDN network and delivered to the audience through the streaming media server. In the prior art, the main Real-Time transmission technical solutions adopted in the interaction process between the anchor terminal and the guest terminal may further include a multi-path technical solution based on an RTMP Protocol (Real Time Message Protocol) and a P2P technical solution based on a WebRTC (Web Real-Time Communication Web page Real-Time Communication), the media stream transmission may be based on an RTMP or hls (http Live streaming), the stream format may be flv (flash video), and the like, and the audio and video encoding and decoding in the interaction scene may adopt encoding technologies such as h.26x. The prior art can basically meet the real-time transmission control of audio and video interactive information of all parties in live broadcasting with wheat in a simple scene with limited resolution.
Data bandwidth required to be consumed by the live broadcast platform belongs to a high service quality level, and interactive information fusion and optimization are realized due to the fact that an interactive object in a live broadcast scene lacks an effective technical means, so that the interactive audio and video data quantity of a main broadcast end and a guest end is large, and transmission real-time performance is possibly influenced. With the development of the video definition of live broadcast between the anchor terminal and the guest terminal towards high resolution, the network bandwidth on the planned route is continuously and rapidly consumed, the data burst flow at the edge of the backbone network is increased, the real-time bandwidth control means among the anchor, the guests and the audiences gradually fails, and the fluency of the live broadcast process is greatly influenced.
Due to the limitation of real-time bandwidth quality, the type, the number and the resolution of interactive objects in a live broadcast scene of continuous broadcasting are also influenced, the interactive objects are difficult to uniformly schedule, only limited resources can be consumed, the interactive objects are simply synthesized in a layered superposition mode, the interactive mode between a main broadcasting end and a guest end is rigid, and redundant information and invalid information are more.
