A method and device for data processing

Abstract

The invention provides a method and a device for data processing. The method comprises: receiving a media packet and an erasure packet corresponding to an M-th erasure frame; adding the received mediapacket to a first cache queue; adding the received erasure packet to a second cache queue; adding the erasure packet to a second cache queue; and adding the erasure packet to a second cache queue; judging whether the media packet in the first buffer queue and the erasure packet in the second buffer queue satisfy a preset condition when the K-th media packet is detected to be lost; restoring the K-th media packet and are added to the first buffer queue by means of a media packet in that first buff queue and an erasure packet in the second buffer queue when the preset condition is satisfied; when detecting that the media packets corresponding to the M-th erasure frame are received completely, organizing the media packets corresponding to the M-th erasure frame in the first buffer queue intovideo frame data. The invention realizes the recovery of the packet loss, reduces the redundancy of the data, improves the ability of resisting packet loss, and improves the real-time property of video transmission and the quality of video viewing.

Description

technical field [0001] The invention relates to the technical field of Internet of Things, in particular to a data processing method and device. Background technique [0002] With the development of science and technology, Internet of Vision technology has been widely used in various industries, such as office, telemedicine, security, emergency command and other fields. The application of Internet of Vision technology has brought great convenience. [0003] When using the Internet of View for video services, there may be packet loss and out-of-order situations. In the prior art, multiple repeated data packets are usually sent to avoid the loss of a certain data packet, but this method increases the data Packet redundancy, and take up more network load. Contents of the invention [0004] In view of the above problems, the present invention is proposed to provide a data processing method and device that overcomes the above problems or at least partially solves the above pro...
