Packet loss detection method, system and media client

Abstract

The invention provides a packet loss detection method, a packet loss detection system and a media client. The packet loss detection method comprises the following steps that: a receiving end acquires packet numbers of received data packets; the receiving end acquires packet total information sent by a sending end; and the receiving end detects lost data packets according to the packet numbers and the packet total information. According to the packet loss detection method, the packet loss detection system and the media client, which are provided by the invention, the initial lost packet can be timely detected under the low cost so as to realize retransmission of the lost packets and the retransmission of the lost packets can be carried out in the process of switching a streaming media server.

Description

technical field [0001] The invention relates to streaming media technology, in particular to a packet loss detection method, system and media client. Background technique [0002] With the popularization of broadband access, the application of streaming media technology is becoming more and more extensive, and when the media code stream is transmitted on the IP network, it will inevitably encounter packet loss, which will lead to blurred screen pauses and intermittent sound changes, seriously affecting Media playback quality. In engineering practice, packet loss retransmission technology is often used to deal with network packet loss problems. According to the specific implementation level, existing packet loss retransmission technologies can be roughly divided into two types: transport layer implementation and application layer implementation. [0003] Among them, the transport layer implements packet loss retransmission by using connection protocols such as Transmission C...

Problems solved by technology

[0009] In order to overcome the disadvantages that the prior art cannot detect the initial packet loss or can detect it but the effect is not good or the cost is high and it is not easy to popularize, the present invention proposes a packet loss detection method, system and media client to be able to detect packet loss at low cost Initial packet loss and further packet loss retransmission, and packet loss retransmission when switching streaming media servers
