Inter-home digital living network alliance (DLNA) equipment discovering and controlling method and device

Abstract

The invention provides a method for performing inter-home digital living network alliance (DLNA) equipment discovery between a local home and an opposite end home. The method comprises the following steps that: a simple service discovery protocol (SDDP) proxy in the opposite end home performs uniform resource locator (URL) rewriting on a retrieval response transmitted from the home DLNA equipmentbased on a universally unique identifier (UUID) of the home DLNA equipment after transmitting the received equipment retrieval multi-cast messages to the home DLNA equipment in the opposite end home in a multi-cast manner, and then transmits the retrieval response which is subjected to URL rewriting to the home DLNA equipment in the local home in a unicast manner, wherein during the URL rewriting, the internet protocol (IP) address and the port number of the URL in the retrieval response are rewritten to be the IP address of a Web proxy server and the port number of a monitored port in a gateway of the local home respectively; and the path part of the URL in the retrieval response is rewritten to be the UUID of the home DLNA equipment in the opposite end home.

Description

technical field [0001] The present invention relates to the Internet field, and more specifically, to a DLNA protocol-based inter-family DLNA device discovery method and its device, as well as a DLNA-based inter-family device control method and device. Background technique [0002] With the continuous development of science and technology, more and more electronic devices are used at home, such as flat-panel TVs, mobile phones, digital cameras, video cameras, audio systems, computers, multimedia players, game consoles, etc. Usually, these electronic devices store different files, such as various audio, photo and video files. If a user wishes to watch or appreciate a file stored on one of these electronic devices, the file must be processed on the electronic device with corresponding processing software before viewing or enjoying. That is to say, if a user wishes to process a file on an electronic device, a corresponding operation must be performed on the electronic device. ...

AI Technical Summary

Problems solved by technology

[0009] (1) With the increase of devices conforming to the DLNA standard in the family, these devices have different IP addresses, which leads to the proxy server of the peer family needing to monitor multiple ports at the same time, thereby increasing the burden of the proxy server, and the scalability is not good it is good

[0010] (2) When a new DLNA device is added in the family, it is necessary to negotiate with the proxy server of the peer family to add a new listening port, which increases the cost of device discovery and control between families

[0011] (3) Increased the probability of "port occupation" conflict
