  19. Wireless Home Network Core Technology u-computing core technologies for device connectivity near PAN But, So many standard competition WLAN (IEEE 802.11) 2.4GHz / 5GHz WLAN Wireless WPAN (IEEE 802.15) HDR UWB WPAN, HDR WPAN Wireless 1394, Wireless USB Bluetooth UWB WLAN: Wireless Local Area Network WPAN: Wireless Personal Area Network USB: Universal Serial Bus UWB: Ultra Wide Band LDR Bluetooth, ZigBee, Location Awareness UWB

  20. SMMD Concept • Present : Service based on SMSD that one media is played from one device is mainly used. • Future : To maximize effect of media at ubiquitous, home should use SMMD that one media cooperatively works with several devices. ne-Media Generation Device Synchronization Real-Sense for U-Home Services ne-media Actuator Ubiquitous Home Devices Audio/Video/Text light Home Server scent video + PMP Cellular text vibration Control Settop Box audio ※ne : any, next,neo ※SMMD : Single Media Multi Device

  21. SMMD Service System Flow • mainly consists of 3 parts : ne-media creation, ne-media synchronization, ne-media presentation Devices Device activation ne-mediacreation Media/device synchronization creation Browser Control A/V Control creation A/V Device Neodata Schema SMMD Browser Main Controller Video Controller H/W Decoder Stored ne-media A/V Device Multi A/V Device Session Manager Multi A/V Streaming Server Neodata authoring Media/Device Synchronization A/V Device ne-media Creation Transport System (Server & Client) ne-media Parser Synchronization Manager Device Control neodata Analyzer Device Mapping DeviceController Control Interface Simulation Simulation Device Device Controller 1 ne-media Authoring Tool Mapping and Profiling Device Device Controller 2 . . .
