Detection method and detection system of remote media playback signal delay

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.

Description

technical field [0001] The invention relates to the technical field of remote media playback, in particular to a method and system for detecting time delay of remote media playback signals. Background technique [0002] With the continuous popularization of smart TVs, the continuous improvement of the intelligence of set-top boxes, and the continuous rise of Internet TVs, TVs have become more and more deeply involved in people's daily work and life, and are playing an increasingly important role. For TV, people are no longer satisfied with simply watching programs, but hope to embed some applications associated with remote media playback signals, such as embedding advertisements, in TVs, set-top boxes, or PC applications and WEB applications. At this time, we often face the problem of time delay (hereinafter referred to as "time delay") of the same remote media playback signal in different areas. For example, audience A in front of a TV and audience B in front of another TV ...
