Embodiment Construction

[0050]In the process of implementing this application, the inventors found that in the current IP-based system, the means of IP data measurement and monitoring are relatively simple, and the real-time monitoring and analysis of the clock synchronization accuracy of the IP stream is usually implemented by professional oscilloscopes and integrated chips based on professional hardware analysis Depth measurement of various IP media streams. This implementation solution is expensive, relies on imports, and usually can only analyze and monitor one IP stream at the same time, and cannot meet the needs of simultaneous analysis and monitoring of multi-channel IP streams in an IP system.

[0051] In view of the above problems, the embodiment of the present application provides a media device traffic accuracy analysis method, which can use the network device as a bridge between the computer device and multiple media devices to be tested, and calibrate the local system time of the computer...

Abstract

The embodiment of the invention provides a media equipment flow precision analysis method and device and a readable storage medium, and the method comprises the steps: correcting local system time through receiving a time calibration message which is transmitted by network equipment and is generated based on clock generation equipment; receiving a media stream data packet which is sent by the target to-be-tested media equipment through the network equipment and comprises equipment state information and equipment stream sending time of the target to-be-tested media equipment; under the condition that the equipment state information represents that the target media equipment to be detected meets the detection standard, obtaining a clock skew result of local system time and equipment stream sending time through calculation; and finally, determining the flow precision state of the target to-be-tested media equipment according to the clock skew result. Through the scheme, compared with the prior art in which expensive professional equipment needs to be provided for flow precision confirmation, the flow precision confirmation of a plurality of pieces of to-be-tested media equipment can be realized without making an improvement on hardware.

Description

technical field [0001] The present application relates to broadcasting and television technology, and in particular, relates to a method, device and readable storage medium for analyzing the flow accuracy of media equipment. Background technique [0002] At present, professional video and audio production and transmission systems based on IP architecture are gradually becoming mature, and many projects have been implemented. Mastering the real-time status of the IP media stream, especially the clock synchronization status of the signal source is of great help to quickly judge the quality of the stream and the healthy operation of the system. In related technologies, IP data measurement and monitoring methods are relatively simple, and the real-time monitoring and analysis of the clock synchronization accuracy of IP streams usually uses professional oscilloscopes, based on professional hardware analysis integrated chips to realize the depth measurement of various IP media str...
