STREAMING MEDIA TRANSMISSION QUALITY EVALUATION AND INFORMATION ACQUISITION METHOD, RELEVANT DEVICE AND SYSTEM

摘要

An embodiment of the present invention discloses a method for evaluating streaming media transmission quality. Initial playback delay information is obtained, and a subjective experience variation value of a user terminal is calculated according to the initial playback delay information, so as to evaluate streaming media transmission quality. The method includes: monitoring a Transmission Control Protocol TCP connection established with a user terminal; obtaining initial playback delay information if it is detected that the TCP connection established with the user terminal is a streaming media service connection; and calculating a subjective experience variation value of the user terminal according to the initial playback delay information. Embodiments of the present invention further provide a device for evaluating streaming media transmission quality, a method for obtaining streaming media information, and a related device and system.
