Abstract

The invention is a UPNP-based protocol network multimedia TV set, realizing the functions of automatic finding, announcing, information interchanging, and other operations, and providing the play control service function for network devices. The TV set supports wireless and wire network environments and supports VXWORKS operating system, and after transplanting TCP/IP, UDP, etc to the VXWORKS operating system, adds an 802.11 protocol applied wireless network interface on the basis of existing mainboard structure of the TV set. Correspondingly, it adds a UPNP protocol stack and an 802.11 wireless network card driving module in a network module. As a UPNP device, it can realize the functions of automatic issuing information and being called for service by the UPNP devices in other networks and it has higher playing quality.

Description

technical field [0001] The invention relates to a network multimedia television, in particular to a network television based on the UPNP interconnection protocol. Background technique [0002] Playing multimedia files in the network environment in the family at present is mostly downloaded or played instantly by the user using a PC to surf the Internet. Due to the high price of existing high-quality displays, the playback effect is poorer than that of existing high-definition televisions, so using home televisions to play network media files has become an inevitable trend in the development of network technology. [0003] With the application of wireless network technology, especially UPNP protocol technology, the equipment in the wireless network can realize an automatic discovery, easy installation, interconnection and resource sharing mode, and wireless equipment based on UPNP protocol technology is gradually being applied. [0004] Existing wireless network technology c...
