Embodiment Construction

[0039] In the present invention, a method of adding a switch state machine (start-off) to the RTSP state machine is adopted to control the RTSP protocol. like figure 1 shown is the flow chart of the present invention; the process of controlling the RTSP protocol through the RTSP state machine includes: establishing a connection between the client and the server, and activating the RTSP session; the client sends an RTSP request message to the server; the server sends the client The terminal sends back a reply message with a status word corresponding to the RTSP request message; the client terminal changes the corresponding state of the state machine according to the status word in the reply message. The corresponding states of the state machine include at least a start state and an end state.

[0040] like figure 2Shown is a schematic diagram of the RTSP state machine involved in the present invention. The RTSP state machine (hereinafter referred to as the adaptive RTSP sta...

Abstract

The invention provides a method for implementing control of real-time stream protocol by state machine, comprising: client end builds connection with server end to activate real-time stream protocol session; the client end sends real-time protocol request message to the server end; the server end returns corresponding answer message with status word to the client end; the client end changes corresponding status of the state machine according to the status word, where the statuses at least include start status and end status. When the TCP of the real-time stream protocol session or the real-time stream protocol session is broke off suddenly, the status switchs to the end status automatically no matter what the state machine is in any status. By adopting a RTSP self-adaptive state machine, it can process various conditions of RTSP protocol operation, really implementing self-adaptive control of overall protocol drive by state machine, simplifying RTSP protocol implementation and enhancing implementing constitutive property and robustness.

Description

technical field [0001] The invention belongs to the field of computer streaming media processing, and in particular relates to a method for realizing real-time streaming protocol (RTSP) control by using a state machine. Background technique [0002] Streaming media is a new way to obtain streaming data such as audio and video from the Internet compared to the traditional "download-playback" way, which can realize real-time transmission and real-time playback of data streams. [0003] At present, in the multimedia real-time control method, the real-time streaming protocol (real-time streaming protocol, RTSP protocol) is mainly used. It is an application layer protocol used to control the sending of streaming media data over an IP network, while providing remote control functions for multimedia streaming files (such as audio and video streams), such as stop, fast-forward, fast-rewind, and positioning Wait. Because it is friendly to the firewall of the network proxy and has t...
