Remote media playing signal time delay test method and test system

Abstract

The invention provides a remote media playing signal time delay test method and a test system. The method includes a first step of carrying out multiple sampling on remote media playing signals of each playing stream in the N playing streams of a server end, a second step of generating first feature codes according to each sampling data, a third step of corresponding to each playing stream, storing each first feature code corresponding to each playing stream, and each sampling instant corresponding to each first feature code, a fourth step of carrying out sampling on a client end at client end sampling instants Ts 2', a fifth step of generating second feature codes according to client end sampling data, a sixth step of obtaining server end signal sampling instants Ts1 corresponding to the first feature codes matched with the second feature codes, and a seventh step of obtaining signal time delay Td of the client end and the server end to the same remote media playing signal based on the server end signal sampling instants Ts1 and the client end sampling instants Ts 2'. The remote media playing signal time delay test method and the test system can effectively and accurately detect the time delay of the remote media playing signals.

AI Technical Summary

Benefits of technology

This technology helps improve upon existing methods that use delayed video signals from remotely playing music or videos over networks such as internet streaming services (IMS). By comparing different sample sequences captured during recording to previous ones, it becomes possible to determine if there was any delays caused due to network congestion or processing issues.

Problems solved by technology

The technical problem addressed in this patented technology relates to improving upon synchronizing between remotely located devices like televisions and internet protocol television systems when playing back content on their own device over wireless networks due to delays from transmitting data through satellite communication channels. This issue affecting both broadcasted video programming providers and streaming services may be exacerbated if multiple users share one channel at once.
