II. Added Feature to TC: 

II. Added Feature to TC Sphere of Management (Cross-Environment TC) To connect different kinds of TC services in any places. Provides a common interface to discover/execute services that are implemented in various ways. Manages the services in some domain and communicates with other SoM. Simple Service Filtering by Service Property Location of the service Area where the UPnP announce is advertised (= Segment of LAN) is not necessarily same as that ‘nearby’ the user. Define the location for each devices (office, cafe, and meeting room) at demos built in a segment of LAN. User ID of the service owner 5 users can experience the demo at the same time. Show the file services only that users create by themselves.

III. Development of TCE for Different Platforms and Devices: 

III. Development of TCE for Different Platforms and Devices To spread TCE: More Attractive Applications With More Various Devices On More Various Networks By More Developers Some part of development is done as a National Project, NICT (National Institute of Information and Communications Technology) Easy Connection of Home Appliances Promotion of IPv6

III-1. TCE on Linux, IPv6: 

III-1. TCE on Linux, IPv6 Port TCE (STEER and PIPE) to Linux, C++ To run on smaller devices More simple structure and functions Smaller size Work more lightly Verify the cross platform connectivity Apache/Axis on Linux <-> IIS/ASP.NET on Windows XP For IPv6 UPnP Library (libupnp developed at SourceForge) is modified to deal with socket communication on IPv6. Web server/Web Service container is Apache/Axis on Linux that can work on IPv6.

III-2. Home Appliances: 

III-2. Home Appliances HDD Video Recorder Popular home appliance in Japan Developed in Java, on Apache/Tomcat/Axis, Linux Linux is one of the standard platforms for embedded appliance To show how to develop TC service on non-Windows platform TC-Services ‘Reserved TV program’ to set reservation information to record TV program Output: TcVideoRecInfo that contains the title, channel and schedule of the program ‘Record’ to set the reservation for recorder Input: TcVideoRecInfo ‘Get Recorded Video’ to select the VideoFile Output: VideoFile Combined with Multimedia Player to watch the recorded TV program Future work UI support by iEPG (Internet Electronic Program Guide) Service coordination through ‘Schedule’ object

Responses to our Activities:FAQ at Demonstration : 

Responses to our Activities: FAQ at Demonstration General How does Fujitsu do business with TC? How does Fujitsu promote the standardization? When will TC become a product? TC System Structure Where are files, in user’s terminal or on a remote server? What kind of wireless connection among devices is used? What is the merit to apply the technology of Semantic Web rather than UPnP, Web Service, or Bluetooth? Does TC have any mechanism for security? SIS System Structure How is the location of device detected? How is the file related to the balloon detected? How much does it cost to set the sensors on the ceiling?

Next Step for More Practical Use: 

Next Step for More Practical Use What is the current problem? To use information appliances efficiently anytime, anywhere To develop devices that can easily connect to various specifications TCE provides the reasonable answer? Any other specifications or technologies can realize it? Semantic Web (RDF, OWL, OWL-S) is Difficult for general developers (not researchers) to understand? Heavy for small devices?
