In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments are further described in detail. It should be understood that this embodiment is only one aspect of the application of the present invention and is not intended to limit the present invention.
RTMP is an acronym for Real Time Messaging Protocol. The protocol is based on TCP, is a network protocol designed for real-time data communication, and is mainly used for audio-video and data communication between a Flash/AIR platform and a streaming media/interaction server supporting an RTMP protocol. The Flash Player is installed on almost all personal computers at present, and the RTMP and the Flash Player are widely applied to the field of live broadcast, so that the Flash Player is an optimal scheme for achieving the purpose that a browser does not have a plug-in to order videos.
In some embodiments, as shown in fig. 1, the access gateway 10 of the present invention is connected to an RTMP video live system 20 and a GB/T28181 video monitoring system 30, respectively, wherein: the access gateway 10 comprises a signaling control module 11 and a data forwarding module 12, and transmission of control signaling exists between the signaling control module and the data forwarding module; the RTMP video live broadcast system 20 comprises an RTMP server and a Flash Player, wherein signaling control interaction and media transmission exist between the RTMP server and the Flash Player; the GB/T28181 video monitoring system 30 includes a signaling server, an SIP server, and a media server, where there is signaling transmission between the signaling server and the SIP device, and there is media transmission between the SIP device and the media server.
The signaling control module 11 is configured to complete signaling transceiving, control scheduling, and protocol conversion between the RTMP server and the signaling server according to a preset first rule; and is further configured to send a signaling instruction to the data forwarding module 12, and perform logic control and routing control on the data forwarding module 12.
As shown in fig. 2, the signaling control unit performs the following operations according to a preset first rule:
the signaling control unit performs registration application to the video monitoring system 30 to acquire camera list information;
when a camera list acquisition request of the live broadcast system is received, returning list information;
when receiving a video on demand request of the live broadcast system, converting a signaling protocol and sending the video on demand request to the video monitoring system 30;
when receiving a request for stopping the on-demand of the live system, the video monitoring system 30 sends a request for stopping the on-demand to the signaling protocol.
And the data forwarding module 12 includes at least one data forwarding unit, and is configured to complete processing and forwarding of media stream data between the live video system 20 and the video monitoring system 30 according to a preset second rule when the signaling control module 11 receives a video-on-demand request of the live video system.
Specifically, the preset second rule includes that after receiving the control instruction of the signaling control module 11, the RTP (real-time transport protocol) packets of the video monitoring system 30 are spliced into a video Stream, and then the video Stream is stripped from a video data encapsulation format defined by a PS (Program Stream, moving picture experts group) and encapsulated, and then sent to the live video broadcast system 20.
The method for splicing the RTP data packets into the video stream comprises the following steps: extracting timestamp information from the RTP data packets, and storing all RTP data packet load data with the same timestamp as one frame to form a frame linked list; in each frame, RTP packets are sequenced according to the data packet sequence numbers and then spliced into a video stream. The method for stripping PS encapsulation from the video stream and then sending the video stream to the live video system 20 comprises the following steps: traversing each frame data of the video stream, searching and stripping the header data guided by the preset mark data, extracting the required network abstraction layer unit to form an RTMP data packet, and then sending the RTMP data packet to the video live broadcast system 20. In the actual processing, the preset flag data includes "0 x000001BA
"0 x000001 BB", "0 x000001 BC", "0 x000001E 0" and "0 x000001C 0", after the header data guided by these 5 flag data are stripped, NALUs (basic data units in video coding standards such as networkabstract layer unit, H264) at the beginning of "0 x 00000001" and "0 x 000001" guided by "0 x000001E 0" are extracted.
It will be appreciated that the number of data forwarding units in the data forwarding module 12 is related to the number of cameras and the number of users that the video surveillance system has access to. For example, by using a single data forwarding unit to process 50 3Mbps code streams concurrently, the number of data forwarding units needed can be calculated by combining the number of cameras and users and the probability of use.
As shown in fig. 3, in the case of no dedicated plug-in, a user may open a browser to send a video-on-demand request (after completing a registration application and acquiring camera list information), the signaling control module 11 converts a signaling protocol and then sends the video-on-demand request to a GB/T28181 monitoring system on-demand system, the video monitoring system 30 sends RTP data to the data forwarding module 12, the module splices RTP data packets into a video stream, and then strips the video stream from PS encapsulation and sends the video stream to the live video broadcast system 20. When receiving a request for stopping on-demand from the live system, the signaling control module 11 converts the signaling protocol and sends a request for stopping on-demand to the video monitoring system 30. In order to ensure the simplicity and intuition of the drawing, a control part among the SIP server, the signaling server and the media server is omitted in fig. 3.
