Embodiment Construction

[0026] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] figure 2 It is a flowchart of a method for transmitting RTP packets according to an embodiment of the present invention. Such as figure 2 As shown, the transmission method of the RTP packet includes the following processing:

[0028] Step S201: Compressing the RTP headers of one or more RTP packets in the RTP packets to be transmitted, wherein the compressed RTP headers include: a sequence number;

[0029] Step S203: Transmit the above RTP packet to be transmitted.

[0030] In related technologies, if a complete RTP header is transmitted for each RTP packet in a session, a large amount of information redundancy will be generated. use figure 1 In the shown method, the RTP headers of one or more RTP packets in the RTP packets to be transmitted are compressed, and the compressed RTP headers include sequence number information...

Abstract

The invention discloses an RTP packet transmission method and device. The method comprises carrying out compressing on RTP headers of one or more RTP packets in a RTP packet to be transmitted, wherein the compressed RTP headers comprise serial numbers; and transmitting the RTP packet. According to the technical scheme provided in the invention, each RTP packet in conversation does not need to be transmitted with a complete RTP header, thereby reducing redundant transmission information and improving network utilization efficiency.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for transmitting RTP packets. Background technique [0002] Before the audio and video data is transmitted in the network, it must be encapsulated first, such as first encapsulated into a Real-time Transport Protocol (RTP) package, and then encapsulated into a User Datagram Protocol (User Datagram Protocol, UDP) packets, Internet Protocol (Internet Protocol, IP) packets, etc. The encapsulated data is much larger than the original effective data, resulting in only a small amount of audio and video data being transmitted, but occupying a large amount of bandwidth. [0003] The RTP protocol specifies a standard packet format for transmitting audio and video over the Internet. It was originally designed as a multicast protocol, but it is often used in unicast applications. Such as figure 1 As shown, the first 12 bytes of the RTP packet header format appear...
