DLNA (digital living network alliance) packaging and transmitting method and system

Abstract

The invention discloses a DLNA (digital living network alliance) packaging and transmitting method and system. The method is suitable for transmitting to a remote network, and comprises the following steps that: the connection between a first electronic device of an area network and a second electronic device of a remote network is completed through a server; a first analog device and a second analog device are respectively established in the first electronic device and the second electronic device; the first analog device monitors a package sent by the first electronic device, and when the first analog device monitors that the package sent by the first electronic device is a DLNA packet package, the DLNA package is transmitted to the second analog device through a connecting wire; and the second electronic device obtains the DLNA package through the second analog device. According to the invention, users can access data of home networks in an external network at any time; networks are integrated by using a point-to-point architecture, so that gateways do not become a bottleneck of the scale growth of home networks; and through network authentication, a situation that unauthorized devices illegally access data of home networks can be avoided.

Description

technical field [0001] The present invention relates to a digital living network alliance (Digital Living Network Alliance, DLNA) encapsulation transmission technology, in particular to a technology for accessing remote digital living network alliance network data. Background technique [0002] Multimedia file sharing has always been one of the most important links in the digital home. In the past when desktop personal computers were the mainstream, the file sharing of the digital home was based on the regional network as the research and development environment. However, in recent years, portable devices such as laptops and tablets With the rise of computers and smart phones, coupled with the popularization of wireless Internet access, the demand for sharing anywhere has emerged. [0003] The Digital Living Network Alliance (DLNA) standard is based on the original network, such as: Ethernet (Ethernet, IEEE803.3u) and wireless network. The main functions of the DLNA standard...

Problems solved by technology

[0005] However, when two electronic devices are located on different networks to transmit DLNA packages, they cannot search for each other through broadcasting, and cannot directly establish a TCP / IP connection
