Abstract

A method for controlling multimedia based on RTSP is disclosed. The method comprises the following steps: a) when the user of the multimedia terminal selects multimedia playback, confirming the status of the multimedia terminal; b) based on the result of step a), generating a PLAY message requesting the selected media data, and transmitting the message via wireless data communication network to transmit the PLAY message; c) determine whether the status of the multimedia terminal changes after step b); and, when the status of the multimedia terminal changes, generate a control message corresponding to the changed status, and This control message is sent to the server.

Description

Technical field [0001] The present invention relates to a method for controlling multimedia based on Real Time Streaming Protocol (RTSP), and in particular to a method for dynamically controlling multimedia based on RTSP, wherein when multimedia services are provided through a wireless data communication network, multimedia terminals are generated based on RTSP Control commands and then media data are provided to the multimedia terminal. Background technique [0002] Currently, users can use multimedia terminals to receive various multimedia services through wireless data communication networks. Multimedia service refers to receiving many kinds of data through wireless data communication network. Generally, multimedia services in wireless data communication networks are charged based on data packets. Therefore, if a user receives a multimedia service, such as a movie, through a wireless data communication network, the user will pay a considerable fee to the service provider. As f...
