Method for Evaluating Streaming Media Transmission Quality and Obtaining Information, and Related Device and System

A device for evaluating streaming media transmission quality, comprising:

• a monitoring module configured to monitor a Transmission Control Protocol (TCP) connection established with a user terminal;
• a first obtaining module configured to obtain initial playback delay information when the monitoring module detects that the TCP connection established with the user terminal is a streaming media service connection;
• and
• a first calculating module configured to calculate a subjective experience variation value of the user terminal according to the initial playback delay information that is obtained by the first obtaining module.

A method for obtaining streaming media information, comprising:

• receiving a request input by a user;
• obtaining initial playback delay information when the request is a streaming media initial playback request, where the initial playback request is used to establish a streaming media playback connection based on Transmission Control Protocol (TCP);
• and
• reporting the initial playback delay information to a server.

A user terminal, comprising:

• a receiving module configured to receive a request input by a user;
• a second obtaining module configured to obtain initial playback delay information if the request received by the receiving module is a streaming media initial playback request, where the initial playback request is used to establish a streaming media playback connection based on Transmission Control Protocol (TCP);
• and
• a reporting module configured to report the initial playback delay information obtained by the second obtaining module to a server.
