Abstract

The embodiment of the invention relates to the technical field of UPNP device discovery, in particular to a UPNP device discovery method. The method comprises the following steps: a control point joins in a multicast list of a router; the UPNP device sends notification packets to the broadcast address and the multicast address of the router respectively; the router broadcasts the notification packet, and multicasts the notification packet according to the multicast list; and the control point acquires related information of the UPNP equipment according to any one received notification packet.According to the UPNP device discovery method provided by the embodiment of the invention, the data can be sent out in multicast and broadcast modes at the same time, the discovery success rate of theUPNP device is improved, and the stability and compatibility of a screen interaction protocol are improved.

Description

technical field [0001] The present application relates to the technical field of UPNP device discovery, and in particular to a method for discovering UPNP devices. Background technique [0002] Currently, if figure 1 As shown, the mobile terminal located in the same local area network can interact with the TV terminal on the screen to realize the sharing of media resources. For example, when the screen of the mobile terminal cannot meet the user's demand for viewing a larger and clearer picture, the mobile terminal can display the current screen image, picture resource or video resource on the TV terminal with a larger display screen through screen interaction . [0003] For different electronic devices in the local area network, because they cannot perceive devices in the local area network other than routers, device discovery needs to be performed before screen interaction. At present, commonly used screen interaction protocols, such as DLNA (Digital Living Network Alli...
