1. The document describes an open source protocol stack called CyberLink that allows Internet services to be accessed through home networking devices. 2. The author is developing Android applications based on CyberLink to use Android devices as a centralized hub for controlling home networks and accessing Internet content on other devices. 3. The applications implement standards like DLNA and UPnP to discover devices, share content, and remotely control playback across a home network without requiring firmware updates on other devices.
![CyberGarageSequence of Android's DMP and DMS
I have implemented a standard DMP and a extended DMS for Android. The DMS is extended to proxy an Internet Service, Flickr.
You can see the Internet contents of the DMS using other standard DMPs such as Sony's BRAVIA and Toshiba's REGZA.

- 2. CyberGarageWhat is CyberLink ? I am developing my applications for Android based on the following protocol stack which is my open source project. CyberLink for Java http://www.cybergarage.org/net/upnp/java/ Basically, the CyberLink is a protocol stack of UPnP*1) with the upper protocol such as DLNA*2). I have ported the source codes into Android already, I am developing the applications now. I could port the source codes easily from Android SDK M5 because the SDK version supported multicast and fixed some major problems. Thanks :-) I have released the protocol stack using other programming languages such as C++, C, Perl. Especially, Nokia joins the project as the developer and the project is used in their consumer product such as their Internet tablet.

- 4. CyberGarageAbstract Concept Recently, there are many networked devices in home but the home devices are isolated from Internet because of some reason now. I would connect the home devices with Internet services using my applications on Android devices. Using my applications, I hope that Android devices will be a personalized central device of the home networking. Using my application, the home devices can see or synchronize Internet contents with no hardware change because the my application emulates the home protocols as a proxy device.
- 5. CyberGarageUse case Plan based on CyberLink - 1 Using my application on Android, the following use cases are available in the future. For the contest, I have implemented only some use cases yet. Using my applications, the user uses the Android device as a networked remote control, selects Internet contents and watches the contents on a other big television. The use case is based on DLNA v1.0 or v1.5. The television of DLNA does't need to change the firmware to watch the Internet contents because the Android device emulates DLNA protocol as the proxy to transfer the Internet contents. 1. Watch Internet contents on Television The user come back home with the networked home devices such as the digital camera, the Android device finds the new devices and uploads the contents into Internet services such as Picasa automatically. 2. Synchronize Home contents with Internet Services Automatically
- 6. CyberGarageUse case Plan based on CyberLink - 2 While you are out, you can access to your networked devices in your home using the Android device. The use case is based on UPnP IGD*4) and the original firewall software which is implemented on Android or other devices such as PC or NAS. 4. Access to Home contents and Devices The Android devices can interrupt and send any notifies of Internet to television whether the user see the broadcast contents in home. The use case is based on DLNA v1.5 or NDT*3) v2.1 in Japan. 3. Notify Internet contents into Television *3) NDT : Networked Digital Television - http://nw-dtv.jp/ *4) IGD : Internet Gateway Device - http://www.upnp.org/standardizeddcps/igd.asp
- 7. CyberGarageBenefit for Android and Google - 1 User of Android devices can use their home networked devices with the Android devices seamlessly, because the application of Android emulates the standard protocol in home networking such as DLNA and NDT. To divert the standard networked devices, Google doesn't need to develop other home electronics such as television directly. The User can see the Internet services across the Android devices by practiced hand of their home networked device easily. 1. Compatibility with Home Netoworked Devices It is hard to implement the service of Internet on networked devices in home such as television directly because the embedded devices has any limitations and it is difficult to upgrade for the new services of Internet. To use the Android devices as the proxy, it is easy to implement and upgrade for the new services. 2. Hardware Independent
- 8. CyberGarageBenefit for Android and Google - 2 Using alert functions of the standard protocols in home networking such as DLNA v1.5 and NDT v2.1, Google can send any notifications of Internet services and advertisement to the users directly. To collect the user's behaviors such as watched contents in home, Google can send the optimized advertisement more. 3. Push Contents and Optimized Advertisement Contents with Ad reception records Ad
- 10. CyberGarageAbstract of Contest Applications Digital Media Player (DMP) ･ Select Contents in DMS ･ Play Contents in DMS I have implemented only my first use case, Watch Internet contents on Television, for the contest now. To explain easily, I create the following four applications as a applications, but the applications connect with the other applications using networking such as DLNA. DMP-1: Search Contents (DLNA) Digital Media Server (DMS) ･ Publish internal contents in Android ･ Publish and Proxy Internet contents using DLNA. Digital Media Controller (DMC) ･ Select Contents in DMS ･ Specify Contents in DMS to DMR Digital Media Renderer (DMR) ･ Play specified contents by DMC. DMC-1: Search Contents (DLNA) DMC-2: Push Contents to Play (DLNA) Proxy Internet Contents Currently, Android emulator has no local interface yet. However, you can see the Internet contents using other DLNA hardwares across the Android's application with no the hardware changes when Android supports the local interface. Because the applications are based on DLNA and emulate the protocol to play Internet contents. Communicate on DLNA
- 11. CyberGarageDetail of Contest Application - 1 Tab Buttons Use the four buttons to select the applications DMP, DMS, DMC and DMR. Set a friendly name for DMS, and restart. Set a keyword to serach photo images of Flickr, and restart. Start or stop DMS. DMS is implemented as a standard media server of DLNA to public the internal contents such as photo images in the SD card, but it is extended to public Internet contents, Flickr, seamlessly. The DMS runs as the HTTP proxy to transfer from the Internet contents to home devices. Server - Digital Media Server (DMS)
- 12. CyberGarageDetail of Contest Application - 2 Player - Digital Media Player (DMP) Search media servers in home network. Content list view. Display the child nodes when the selected item is the container node or the media server. Display the contents when the selected item is the item node. Select Item Node Return the parent content list view. DMP is implemented as a standard media player of DLNA. I have implemented using VideoView to play the movie contents, but the function is not run normally yet.
- 13. CyberGarageDetail of Contest Application - 3 Controller - Digital Media Controller (DMC) Search media servers in home network. Content list view. Display the child nodes when the selected item is the container node or the media server. Display the contents when the selected item is the item node. Select Item Node Return the parent content list view. DMC is implemented as a standard media controller of DLNA. Basically, the functions of the DMC is same as DMP, but DMC sends the selected contents to DMR without displaying. It is a core function to implement my push type applications. Renderer - Digital Media Renderer (DMR) DMR is implemented as a standard media renderer of DLNA. Finally, I will not add the application to my integrated application because I will use the other standard DLNA device such as television for DMR.
