Problems solved by technology

[0014] Based on the above processing flow, in the technical implementation of the existing RTSP, once the session is established and starts to play (that is, in the process of data playback), the session will not allow new SETUP messages, so the current playback data cannot be distributed to Other clients (such as TV wall, etc.)
For example, when an observer is replaying on a certain client, if he finds a key event and wants to replay the data at this time on other clients and analyze it with other observers, the current technology cannot achieve this.

Embodiment Construction

[0046] by figure 1 Refer to the network model schematic diagram for the present invention, the present invention proposes a kind of media flow data replication method, this method is applied in the monitoring system that comprises EC, IPSAN, VM server, DM server and VC, contains XP and Web-based UI; it should be noted that the VC interacts with the VM server through the SIP (Session Initiation Protocol) message to negotiate with the VM server, and the VC negotiates with the DM server through the RTSP message when playing back data; since the RTSP message is used to implement data playback, subsequent The playback data takes RTSP data stream as an example.

[0047] Such as image 3 As shown, the media stream data replication method includes the following steps:

[0048] Step 301, VC1 requests to send the RTSP data stream sent to itself to VC2 at the same time.

[0049] Before this step, VC1 has established a session with the DM server, and the DM server sends the RTSP data s...

Abstract

The invention discloses a media stream data copying method and equipment. The method comprises the following steps that: a design management (DM) server acquires the Session ID of real time streaming protocol (RTSP) data stream, and the information of other addresses and ports for a video camera (VC) to receive the RTSP data stream; and the DM server searches the RTSP data stream which is sent to the VC through the Session identity (ID), and sends the RTSP data stream to other VCs through the information of the addresses and ports when the RTSP data stream which is found is sent to the VC. In the invention, when the RTSP data stream is sent to some VC, the RTSP data stream is simultaneously sent to other VCs, so that the copying and distribution of the RTSP data stream are realized.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for duplicating media stream data. Background technique [0002] In the video surveillance system, the data needs to be stored in the storage device, and when the data is queried and played back, the data needs to be sent to the client. In the above scenario, RTSP (Real Time Streaming Protocol, real-time streaming protocol) is the most widely used transmission control protocol, RTSP can control the transmission of streaming media data on the IP network, and provide "VCR ( Video Cassette Recorder (cassette tape recorder) mode" remote control functions (such as stop, fast forward, fast rewind and positioning, etc.). The main methods in the current RTSP are DESCRIBE (media description), SETUP (session establishment), PLAY (play), PAUSE (pause), OPTIONS (query), TEARDOWN (session end), ANNOUNCE (notification), etc. [0003] In the prior art, such as figu...
