Embodiment Construction
[0025] figure 1 It is a flow chart of Embodiment 1 of the audio and video transmission control method of the present invention, such as figure 1 As shown, the method includes:
[0026] Step 101, the target network device receives each data message sent by the source network device in turn, and establishes a cache queue when receiving the first data message, and the data message contains audio and video data from the source network device The server receives the receiving time information and message number information of the data message;
[0027] In this embodiment, after the audio and video collection device sends the collected audio and video data to the audio and video server, the audio and video server sends the audio and video data to the client device in real time or after receiving a request from the client device. Generally speaking, there is the following network connection architecture between audio and video servers and client devices, such as PCs: the audio and ...

The invention provides an audio and video transmission control method and an audio and video transmission control device. The method comprises the following steps: a piece of target network equipment receives data messages sequentially sent by a piece of source network equipment and establishes a cache queue when receiving the first data message, wherein the data messages contain receiving time information and message number information, received by the source network equipment from an audio and video server, of the data messages; the target network equipment determines to send the time sequence and time interval of the data messages to a piece of client equipment according to the received message number information and receiving time information contained in the data messages; and the target network equipment sends the data messages in the cache queue to the client equipment based on the determined timing sequence and time interval when preset sending conditions are met. After receiving the data messages sent by the source network equipment and carrying message number information and receiving time information, the target network equipment controls the sending time sequence and time interval of the data messages to ensure the transmission quality of the data messages.
Description
technical field [0001] The invention relates to network communication technology, in particular to an audio and video transmission control method and device. Background technique [0002] A typical audio and video monitoring system consists of three parts: front-end monitoring subsystem, IP transmission network and back-end client. Among them, the front-end monitoring subsystem mainly transmits the acquired audio and video data to the audio and video server for storage and transmission to the back-end client through devices such as cameras and microphones; the IP transmission network mainly includes the sending end network equipment and wireless wide area network and other wireless ways to connect to the network equipment at the receiving end to send the audio and video data packets in the audio and video server to the back-end client; the back-end client mainly includes such as management platform, display device, etc. for users to Analysis and monitoring of audio and vide...
