Embodiment Construction

[0041] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0042] A method for compensating for packet loss in real-time media streams, comprising:

[0043] Steps for the receiver to detect packet loss in real time;

[0044] After the receiver detects the packet loss, the receiver sends the smoothed packet loss rate to the sender;

[0045] The sender selects the corresponding redundancy multiple according to the received smoothed packet loss rate, and sends the corresponding redundant packet according to the selected redundancy multiple;

[0046] The receiver recovers the data according to the received redundant packets.

[0047] In the packet loss check, the receiving end sets a fixed packet loss detection timer.

[0048] The environment in which this method is applied is image 3 shown. Preferably, a dynamic real-time inspection is performed on the streaming media, and a dynamic packet loss compensation ...

Abstract

The invention discloses a real-time packet loss compensation method for media stream. The method comprises is as follows: a receiving party dynamically tests packet loss in real time; when the packet loss is tested, the receiving party sends smooth packet loss rate to a sending party; the sending party selects corresponding redundancy multiple according to the size of the smooth packet loss rate and sends a corresponding redundancy packet according to the selected redundancy multiple; and the receiving party restores data according to the received redundancy packet. According to the real-time packet loss compensation method, the problems of packet loss compensation and low cost are solved.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a compensation method for real-time media stream packet loss. Background technique [0002] At present, with the development of mobile Internet, various APPs based on Internet communication are widely used, and these APPs will inevitably face the problem of packet loss in real-time streaming media transmission on the Internet, and packet loss is the main factor affecting the quality of audio and video . [0003] Characteristics of Internet packet loss: [0004] 1. Instantaneous packet loss: the packet loss is not serious, occasionally 1 to 3 packets are lost, such as figure 1 , this situation has little impact on voice quality. [0005] 2. Continuous random packet loss: serious packet loss affects voice quality, such as figure 2 , this kind of packet loss can be completely recovered through the FEC technology. [0006] There are two existing methods to solve the proble...
