Embodiment Construction

[0018] Such as Figure 1-Figure 3 As shown, the media player under the LINUX operating system based on the UPNP protocol of the present invention has a UPNP protocol stack added in the application program module to become one of the UPNP devices in the network.

[0019] After the media player compiles the UPNP protocol stack into the application program module, it only increases automatic discovery and interoperability with other UPNP devices. After the UPNP protocol stack releases the media player on the network, when other UPNP devices call the player to play media files, the transmission of audio and video files still uses transmission protocols such as HTTP, RTSP or RTP.

[0020] Such as figure 1 As shown, the application program module of the media player of the present invention mainly includes a content transmission subsystem, a format decoding subsystem, an audio and video transmission service module, a connection management service module and a player control service...

Abstract

The invention relates a Media Player of LINUX system based on UPNP protocol, making the present LINUX operation system as platform using UPNP protocol technology, and being applied in desktop and embedded operation system. The Media Player uses the present video and audio file transmitting technology, without adding any hardware, adds a control module based on UPNP protocol for realizing automatic finding and inter operation functions of platform in network and supplying users with sharing the network resources. The platform can realize automatic publishing the news information and using by UPNP equipment in other network functions, becoming the shared media file processing terminal in network without manual installation by users; and it can be applied in desktop LINUX and embedded LINUX operation system; using the universal interface and soft decoding mechanism, its transportability is remarkable when automatically detect software and hardware environment and generate configuration file and upload decoder.

Description

technical field [0001] The invention relates to a player for playing multiple audio and video format files under the Linux operating system, specifically, the player is embedded with UPNP protocol, and can automatically provide media playing services to other devices in the UPNP wireless network. Background technique [0002] At present, with the development of various wireless network technologies, especially the use of the 802.11 protocol, the existing wireless network has shown its advantages such as convenient installation and flexible use. In order to realize interconnection and resource sharing between wireless devices, UPNP protocol technology has been applied in wireless networks. [0003] UPNP protocol technology is an intelligent interconnection protocol based on the TCP / IP protocol, which can provide interoperability functions such as automatic discovery, network broadcasting, and information interaction between networked devices under the premise of "zero configu...
