Problems solved by technology

General download software needs to download according to the URL address of the resource. In order to improve the download speed, such software usually uses multi-threaded parallel download, which may greatly reduce the performance of streaming media websites.
In addition, due to limited network bandwidth, when users browse network streaming media content, it is often not smooth and often pauses. Users hope to make full use of the data traffic already generated during the browsing process to improve the quality of browsing streaming media content on a low-bandwidth network

Embodiment 1

[0029] With reference to Fig. 1, in the present embodiment, the stream media content downloading method based on data characteristic comprises the steps:

[0030] 1. Start the packet capture thread

[0031] By setting the working mode of the network card to promiscuous mode, all data packets passing through the network card can be captured. In this embodiment, the open-source WinpCap project is used as the packet capture thread.

[0032] 2. Open the link address containing the video content, and save the captured data package. The general download software in the prior art needs to directly point to the link address of the downloaded resource before downloading. The link address required in this embodiment refers to a link containing video content. The link is located on the web page browsed by the user, and does not need to directly point to the downloaded resource.

[0033] Compared with data packet capture, writing file operation is a slow process. In order to avoid data ...

Abstract

The invention relates to a downloading method of stream media content based on data character, comprising: starting data package seizing wire; opening the link address containing video content and buffer memorizing the seized data package in the form of binary data stream in a buffer file. The buffer file is read and a number of conversational files are separated based on the conversation terminal. On the basis of the size of the conversational file and the opening code of the media content in the said file, the said conversational file is determined whether the media content is in the conversational file or not, and the conversational file without the media content is deleted. The data packages in the conversational file are read in turn based on the conversation index file and the retransmission package and error package are deleted on the basis of the sequence number and affirm number in the data package, and then the effective media data package is ordered and stored in the new media content file. Only page address with media content is provided to accurately download the required media content without reducing the website performance of stream media.

Description

technical field [0001] The method belongs to network resource downloading, and in particular relates to a streaming media content downloading method based on data characteristics. Background technique [0002] With the construction of high-bandwidth networks, network streaming services are developing rapidly. Network media search technology has become a necessary means to quickly find the required resources, and network video search is the most important technology. The network video search technology first obtains the video content, and then extracts the color, texture and other features of its key frames and puts them into the database for users to query. At present, how to obtain video resources has become a bottleneck in the development of network video search technology. General download software needs to download according to the URL address of the resource. In order to improve the download speed, this kind of software usually uses multi-threaded parallel download, w...
