2results about How to "Reduce bandwidth waste" patented technology

This invention relates to the fields of audio and video playback technology and network communication technology, specifically a dynamic control method and system for video playback caching. By introducing intelligent prediction models, dynamic weight allocation algorithms, and scene association mechanisms, it achieves precise adjustment of video player caching duration, download speed, and external parameters, thereby maximizing the utilization of the player's local cached content, improving bandwidth utilization, reducing CDN bandwidth costs, and minimizing playback stuttering. Furthermore, this invention provides dynamic parameter and intelligent algorithm configuration interfaces for external users, allowing them to adjust caching control strategies based on multiple different parameters and business scenarios to achieve the optimal caching strategy for their own business.

The invention discloses a point-to-point audio and video call system based on custom signaling. A media plane adopts a mature WebRTC protocol, and a signaling plane designs a load domain of the MQTT protocol by taking the MQTT protocol as a carrier to form a custom signaling. The signaling naming mode refers to the SIP protocol. An MQTT server needs to be set up to transmit signaling, and the server only carries out forwarding and does not carry out any processing on a signaling message. A client needs to customize a signaling state machine to realize session management so as to support the functions of call initiation, automatic hanging up when an opposite party is busy and the like. Different from the SIP protocol, the self-defined signaling does not need a special protocol server for protocol processing, so that the call establishment time delay is shortened. Because the MQTT protocol is a binary protocol, compared with the SIP protocol, the MQTT-based self-defined signaling has the advantages that the flow consumption of hundreds of bytes is reduced on the signaling surface, and the bandwidth waste is reduced.
