Embodiment Construction

[0058] Figure 1 ~ Figure 3 Shown is an embodiment of the invention. In this embodiment, a multimedia adaptation system between different types of devices based on UPnP, such as figure 1 As shown, including media server, media player and AV controller. The AV controller is located in the middle of the transmission channel between the media server and the media player, and can be regarded as a middleware component (receiving the content from the media server and sending the adjusted and suitable content to the media player). The actual AV content is transmitted from the media server to the media player via the AV controller through an out-of-band network transfer protocol (such as FTP or HTTP).

[0059] 1. Media server

[0060] It is used to provide multimedia content and content browsing services, as well as services such as receiving device control, connection management, and AV transmission. One of its important purposes is to let the AV control point list the content th...

Abstract

The present invention discloses a multi-media adaptive system among different types of equipments based on UpnP. The system comprises: a media server, a media player and an AV controller. The AV controller is located between the media server and media player as an middleware component, and is used for receiving the content from the media server and transmits the processed content to the media player, and according to the obtained transmission protocol, file format and device information used in both sides, making the adaption treatment for the media content, and sending the adapted media content to the media player. The invention also discloses a method thereof. The present invention is improved based on UpnP AV, thereby achieving the information interaction and multi-media resource sharing among UpnP AV equipments sustaining different treaties and file layouts in the network.

Description

technical field [0001] The present invention relates to a network information communication technology, in particular to a multimedia adaptation system between different types of devices based on UPnP (Universal Plug and Play) protocol and a multimedia content adaptation method thereof. Background technique [0002] At present, in the local area network of a family or a company, the requirements for sharing network resources and service functions are becoming more and more prominent. With the development of various wireless network technologies, interconnection and resource sharing among wireless network devices have been realized. The UPnP (Universal Plug and Play) protocol is a network application layer protocol based on TCP / IP. The wireless network based on the UPnp protocol can realize mutual discovery, interface declaration and other Information exchange and other interactive operations, so that there is no need to specially configure web servers and provide device loa...
