Live video matching method and system

摘要

A live video matching system provides a matching service between a video demander and a video provider. An orchestration module of the system dynamically adjusts live services provided by SDN edge devices according to network available resources. An SDN edge device of the system dynamically converts and integrates multiple video streams to generate a virtual channel based on results of matching within multiple requests for videos and provides live video channels for interested users.

1. A computer-implemented method, executable by a processor of a live video mate system, the method comprising:
sending a virtual channel request for a live video service via a first client, where 5 virtual channel request records at least one live video channel in which the first client is interested; registering the virtual channel request to a live matching module via a live register module of the live matching module; sending the registered virtual channel request to at least a second client via the live matching module; when receiving the virtual channel request, sending a video providing request, by second client, via a live event publishing module; finding a second Software Defined Networking (SDN) edge device through an orchestration module and directing a video transmission path of the second client to the second SDN edge device using live event publishing module; transmitting live video streams corresponding to the virtual channel request to a second stream receiving module of the second SDN edge device via the live event publishing module; subscribing at least a first channel via the live event subscribing module; finding a first SDN edge device providing the live video streams corresponding to a concert channel via the orchestration module; directing a first transmission path of the first client to the first SDN edge device; calculating an optimized transmission path according to service configurations and network statuses retrieved by a resource managing module; deploying the live video service requested by the first client to the first SDN device residing at the optimized transmission path; converting and integrating the live video streams to create a virtual channel corresponding to the live video service using a virtual channel composing module of the first SDN edge device; and retrieving the live video streams corresponding to the live video service via the virtual channel through a first streaming service handling module of the first SDN edge device.
