Embodiment Construction

[0040] Embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0041] method embodiment

[0042] figure 1 It is a flow chart of an embodiment of the method for receiving and processing RTP data packets according to the present invention, such as figure 1 As shown, this embodiment includes:

[0043] Step S102: receiving RTP packets from the network;

[0044] Step S104: performing primary buffer pre-sorting processing on the received RTP data packets;

[0045] Step S106: Perform secondary buffering on the pre-sorted RTP packets.

[0046] This embodiment can effectively utilize the arrival time gap of the network data packets to pre-sort the data packets, balance the processing complexity of the primary buffer and the secondary buffer, simp...

Abstract

The invention discloses a method and a device for receiving RTP data packets. The method comprises the following steps of: receiving RTP data packets from a network; performing first-level buffering and pre-ordering of the received RTP data packets; and performing the second-level buffering of the RTP data packets undergoing the pre-ordering, wherein a queue group serving as the first-level buffer is used for the first-level buffer and pre-ordering treatment of the received RTP data packets, and the queue group comprises a linked list group and an array group. The device has the advantages of overcoming the defect of low processing efficiency of the RTP receiving mode existing in the prior art and improving the receiving efficiency of the RTP data packets.

Description

technical field [0001] The present invention relates to streaming media and other data transmission technologies in the communication field, and in particular to a method and device for receiving and processing Real-time Transport Protocol (RTP) data packets. Background technique [0002] RTP is a standard transport protocol for streaming media services, formulated by The Internet Engineering Task Force (IETF for short), and its standard document is RFC 3550, which specifies the format of the RTP packet. In all streaming media-related services, almost all media content needs to be encapsulated into RTP packets before being transmitted on the IP network. Due to the characteristics of the RTP protocol itself and streaming media services, the following problems are generally encountered when processing RTP packet reception: [0003] A. Since the bottom layer of the RTP protocol is generally carried by the UDP protocol, the transmission is unreliable. Problems such as packet lo...
