Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0042] like figure 1 As shown, the present invention includes a resource monitoring module, a data transceiving module, a transcoding module, a control module, and a scheduling module. The resource monitoring module is used to monitor the use of resources in the cloud computing platform. It is divided into two levels: the first layer is the physical resource layer, which is responsible for monitoring the use of resources such as CPU and memory of the physical server cluster equipped with the cloud computing platform. , the second layer is the virtualization resource layer, which monitors the use of resources such as CPU and memory inside the running virtual machine. The resource monitoring module periodically analyzes and sorts out these resource information and reports it to the scheduling module; Forward the video stream sent by the client a...

Abstract

The invention provides a cloud computing-based transcoding and distribution system for a video conference. The system comprises a control module, a scheduling module, a transcoding module, a data transceiving module and a resource monitoring module. The system is deployed in a virtual machine at the cloud end. The scheduling module is used for deploying abstract nodes in an assembly line into actual virtual machines. The data transceiving module and the transcoding module can realize actual transcoding and distribution operations of a video stream under the control of the scheduling module. Simultaneously, the resource monitoring module is used for real-time monitoring of states of all the virtual machines and used for a computing task distribution strategy of the scheduling module. The system provided by the invention effectively solves the video transcoding problem caused by a variety of clients in the video conference by utilizing cloud computing services.

Description

technical field [0001] The invention belongs to the field of video conferencing, and in particular is a transcoding distribution system based on cloud computing, which realizes low delay of transcoding distribution and reduces power consumption by controlling and scheduling each task unit and virtual machine. Background technique [0002] With the rapid development of computer hardware and network technology, traditional communication methods such as telephone and fax can no longer meet people's deep-seated communication needs. In recent years, multimedia communication with audio and video as the main transmission object has become a research hotspot in the field of communication. . As a modern office system, the video conferencing system can interconnect the real-time scenes and voices of different venues, so that the participants have the feeling of "face-to-face" conversation. With the further improvement of communication technology, high-quality multimedia video confere...
