Problems solved by technology
The former requires the transmitting end and the receiving end to have two or more encoding and decoding capabilities at the same time, and requires a large amount of communication resources to encode in multiple ways, resulting in a huge channel load and delay
The latter needs to increase the bandwidth, which makes the compensation process more complicated

The invention provides a packet loss recovery method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of obtaining serial numbers of two adjacent received voice frames; calculating the difference value of the serial numbers of the two received voice frames; under the condition that the serial number difference value is greater than a preset numerical value, determining a target difference value range to which the serial number difference value belongs in a plurality of preset difference value ranges; and recovering a lost packet generated between the two received voice frames through a packet loss recovery mode corresponding to the target difference value range. Through the technical scheme of the invention, a proper packet loss recovery mode can be selected according to different numbers of voice frames in the lost packet, so that the recovery degree of the packet loss can be ensured to the greatest extent, the quality of voice information is ensured, and the user experience is improved.
Description
【Technical field】 [0001] The present invention relates to the technical field of communications, in particular to a packet loss recovery method and device, electronic equipment, and a computer-readable storage medium. 【Background technique】 [0002] In daily voice communication, voice information often loses packets due to various interferences during transmission. The lack of voice information caused by packet loss will seriously affect the user's perception experience. [0003] At present, in related technologies, various encoding methods may be used to resist packet loss, or to compensate for lost data packets based on redundant data and redundancy levels. The former requires the transmitting end and the receiving end to have two or more encoding and decoding capabilities at the same time, and requires a large amount of communication resources to perform encoding in multiple ways, resulting in extremely high channel load and delay. The latter needs to increase the bandw...
