Abstract The remote control and media sharing of consumer devices are key services for smart living. The involving of mobile devices into these services has become a technology trend. Existing solutions to these services restrict these devices to be located in the same local network. In this paper, we design and implement an integrated architecture that supports the outdoor remote control to home devices and the sharing of digital media among indoor and outdoor devices. By following the digital home related standards, we show our system design with the details of hardware and software components. Keywords DLNA

1 Introduction With the popularity of digital consumer products, digital content can be seen everywhere. For the easy sharing of digital media such as videos, photos, and music between these consumer products, the Digital Living Network Alliance (DLNA) was initiated in 2003 to define interoperability guidelines [1, 2]. The underlying technology is Universal Plug and Play (UPnP) [3] for media management, discovery, and control. The UPnP, which includes a set of standard network protocols such as TCP/IP, HTTP, and Simple Object Access Protocol (SOAP), enables digital devices having networking capability to be connected. DLNA compliant devices can seamlessly discover each other’s presence on the same home network and share functional services or media content with each other. Four types of DLNA devices are defined in the standard: DMS, DMC, DMP, T.-H. Yu S.-C.

and DMR. A Digital Media Server (DMS) stores and provides media content to other types of devices. A Digital Media Controller (DMC) can discover media content and command a Digital Media Renderer (DMR) to play the content. A Digital Media Player (DMP) can discover and play media content directly, which can be considered as the combination of DMC and DMR. The media sharing between DLNA supported devices contributes significantly to our comfortable life. By integrating sensor technology and automatic control to these home appliances, some research efforts [4–6] have been done for achieving a smart living environment. With the popularity of smart phones, using a mobile phone to monitor and control the living environment becomes a potential service model. For example, a mobile user when being out of home can retrieve and play media streaming from an indoor DMS by connecting the mobile phone to the home network using the Session Initial Protocol (SIP) [7]. In this paper, we provide a service platform using smart phones that can remotely access and control any home appliances. The home app
