17,18; Plate body one end limit portion sets gradually power interface 1, audio track delivery outlet 2, component output interface 3, S terminal 4, digital figure interface 5, network interface 6; Digital figure interface 5 belows are provided with digital figure controller 12; Plate body other end limit portion sets gradually integrated device electronics interface 16, infrared interface 19, panel interface 20, USB (universal serial bus) 21,22, indicator light 24; Plate body one side portion is provided with digital video output+synchronizing signal interface 23; Wherein audio track delivery outlet 2, component output interface 3, S terminal 4, digital figure controller 12, real-time clock (RTC) 8, USB controller 10, flash memory 11, synchronous dynamic random access memory 14, wireless network card interface 15, integrated device electronics interface 16, infrared interface 19, digital video output+synchronizing signal interface 23 connect central processing unit 13; USB (universal serial bus) 21,22 connects USB controller 10; Network interface 6 connects ethernet controller 9; Digital figure interface 5 connects digital graphics controller 12.

The utility model can be decoded to the video source of multiple form (MPEG, MPEG2, MPEG4, WMV etc.), support to play the high definition quality video, and quicken in conjunction with 2D, can be according to user's real needs, be chosen in the wired or wireless LAN environment, realize the broadcast of media file.

The utlity model has following characteristics:

1, except supporting the cable LAN pattern, also support the WLAN (wireless local area network) pattern, this makes communication between the media device break away from the constraint of distance and cable, and the operational mode of equipment is more flexible, sets up the key technology node in the evolution for Digital Media Center.

2, can pass through corresponding interface, as the media server end of network flow-medium player, wireless display instrument, WirelessHD Digital Television, use very extensively, be that traditional media Broadcast Control plate can't be realized.

3, in decoding, broadcast and the form support for video advantage is arranged also, support media formats such as MPEG, MPEG2, MPEG4, WMV and all kinds of image, sound comprehensively.Cooperate 2D to quicken, make that probability such as ossified in the video playback, frame-skipping reduces greatly, picture is more smooth.
