As shown in fig. 1 and 3, in a first aspect of the present application, a method for converting a converged media protocol is provided, including the following steps:

and encapsulating the UDP datagram into a new IP datagram, performing scheduling processing through SDN, performing scheduling conversion according to the requirement of target configuration, and then transmitting to the target equipment.

In this embodiment, the audio and video signals of the TS stream are filtered by removing the encapsulation of different transport protocols from the IP multimedia, and the different transport protocols are converted into UDP TS protocols compatible with the SDN system by adopting a manner of encapsulating the transport protocols of the UDP multicast stream, so as to realize fusion scheduling and transmission of the fusion media. Because different requirements exist for making and propagation paths, corresponding signal formats are also different, including high definition, standard definition, 4K, 8K, non-compressed SMPTE2110, shallow compressed JPEG2000, JPEG XS signals and the like, the application utilizes an input module to receive a stream protocol, analyzes an IP Data packet of the stream protocol, wherein the stream protocol comprises RTMP, SRT, RTSP, RTP and NDI, specifically, the RTMP protocol is an open source protocol, transmits a datagram in a packet form, and comprises two parts of a Chunk Header and Chunk Data, as shown in fig. 4, wherein the Chunk Header comprises a Basic Header, a Message Header and an expansion timestamp Extended Timestamp, the Basic Header is used for storing CS ID and a Chunk Type for determining the Type of the Msg Header, the Message Header comprises related information of a transmitted Message, the Type is determined by the Chunk Type, and the expansion timestamp is a timestamp expansion bit carried by the Message Header. Furthermore, the block Data Chunk Data is Data transmitted by a datagram, namely an audio/video signal, the packet header signal is removed when the input module receives the RTMP protocol, and the block Data Chunk Data is obtained by filtering and is prepared for subsequent UDP encapsulation. Furthermore, when the RTMP transmits the audio and video signals, the push stream and the pull stream are considered, and the method can support two modes of pushing and pulling to acquire the audio and video signals, so that TS audio and video signals are analyzed.

As shown in fig. 5, the SRT protocol includes an information Packet Data Packet and a Control Packet, and is distinguished by a flag bit of the SRT header, wherein 0 represents the information Packet, 1 represents the Control Packet, and further, the Control Packet includes a Handshake, an acknowledgement ACK, a negative acknowledgement NAK, an acknowledgement ACK for an acknowledgement, a keep connection keep, and a close connection Shutdown. And the input module receives the SRT protocol, removes the packet header signal after the SRT handshake is successful, and analyzes the required TS stream audio/video signals.

RTSP is an application layer protocol in the TCP/IP protocol system, and RTSP establishes and controls one or more time-synchronized continuous stream media. As shown in fig. 6, the input module receives the RTSP protocol, and after connection is established, the packet header is removed to parse out the required TS audio/video signal.

The RTP protocol supports the encapsulation of streaming media data and realizes the real-time transmission of the media stream, and each frame of RTP packet consists of a Header and a Payload data Payload, wherein the first 12 bytes of the Header are fixed, the Payload data is audio/video data stored in each RTP data packet, as shown in fig. 7, the Header is removed when the RTP protocol is received, and the TS audio/video signal is analyzed.
