Embodiment Construction

[0025] The present invention will be further described below in conjunction with specific embodiments.

[0026] The system architecture of the present invention includes:

[0027] Data receiving module: responsible for obtaining the data of the whole network through network sniffing.

[0028] Data segmentation module: responsible for dividing the received complete IP packet into each packet header.

[0029] Data packet parsing module: responsible for parsing the packets of each layer, such as MAC layer, IP layer, transport layer, service layer, and header parsing of each layer.

[0030] TCP data buffer module: responsible for reorganizing TCP data, eliminating duplicate packets, and reorganizing out-of-order packets to achieve the purpose of data order at the sending end.

[0031] Core ts stream data acquisition module: acquire the required ts stream data through algorithms. The specific algorithm is as follows: because TS data has particularity, that is, fixed length and f...

Abstract

The invention provides a method and system for intelligently acquiring video data in a network. Data from an MAC address layer to a final protocol layer is obtained through network sniffing, an IP packet header is removed, each layer of message is analyzed, whether a transmission protocol is a TCP or a UDP is judged, the messages are processed respectively, and video data screening is carried out through an algorithm. By means of the method and system, signaling layer data and application layer data of each OTT application can be synchronously captured, and the problem that due to anomaly and ageing of transmission environments or network firmware, complex factors such as long transmission time delay, disordered packets and repeated packets appear, and accordingly the video data is difficult to capture is solved.

Description

technical field [0001] The invention belongs to the field of video technology, and in particular relates to a method and system capable of intelligently acquiring video data from a network. Background technique [0002] With the development of mobile smart terminals and the popularization of FTTH, more and more mobile Internet terminals and home terminals have begun to use a series of OTT video applications. With the increase in the number of OTT applications, various resources in network equipment are facing challenges. Great challenge. The bandwidth consumption generated by OTT applications is gradually increasing the load on the network. Therefore, synchronously capturing the signaling layer data and application layer data of each OTT application and analyzing the impact of each OTT video service on the network side has become an urgent problem to be solved. In practical applications, during the process of OTT application signaling from the sender to the receiver, compl...
