In this paper, a digital signal processing method of AFC (automatic frequency control) is proposed for a home use VCR system. The proposed method has the ability of frequency tracking of a wide range. Implemented with digital circuits, the system is to be used in a digital video system and saves the cost of a hardware compared with a conventional analog automatic frequency control method using several PLL's in case of making home use VCR systems compatible with several TV systems.

This study is about finding effects of home appliances to home furnishing. Recently, home appliances go beyond smart by technology development to show design integrated with furniture. Accordingly, this study is First, from the perspective of home furnishing, I examined the meaning of living space for millennial. Second, I investigated home appliances that recently released for millennial, and analyzed appliances trends, focused on product concepts and styling keyword. Third, conducted in-depth interview focusing on four parts : meaning of space, experience of home- furnishing, appliance and interior, feeling of current appliances. Research has shown that design considered space relevance can make home appliances the main of interior. Future studies will need to validate quantified statistical data. Through this study, I hope that will help to set the role and design direction of home appliances in the future.

This paper investigates potential favor and intention for acceptance of digital home services through the situational inducement. The result shows that digital home services for the interactive TV, security management, family management and geographical image affect users' intention for acceptance. And it shows that favorable attitudes of the interactive TV services increase in the younger generation and internet users, favorable attitudes of the family management services increase in the thirties, and favorable attitudes of the medical management services increase in the ages of the fifties. In addition it shows that relationship between favor and intention for acceptance of digital home services affects affirmatively, which was illustrated in the coefficient value (0.661) of the R-square by the regression analysis.

Wireless 1394 over IEEE802.15.3 must allow a data reserved for delivery over a wired 1394 network to be delivered over an IEEE802.15.3 wireless network through bridging IEEE 1394 to IEEE802.15.3. Isochronous transfers on the 1394 bus guarantee timely delivery of data. Specifically, isochronous transfers are scheduled by the bus so that they occur once every $125\;{\mu}s$ and require clock time synchronization to complete the real-time data transfer. IEEE1394.1 and Protocol Adaptation Layer for IEEE1394 over IEEE802.15.3 specify clock time synchronization for a wired 1394 bus network to a wired 1394 bus network and wireless 1394 nodes, which are IEEE802.15.3 nodes handling 1394 applications, over IEEE802.15.3. Thus, the clock time synchronizations are just defined within a homogeneous network environment like IEEE1394 or IEEE802.15.3 until now. This paper proposes new clock time synchronization method for wireless 1394 heterogeneous networks between 1394 and 802.15.3. If new method is adopted for various wireless 1394 products, consumer electronics devices such as DTV and Set-top Box or PC devices on a 1394 bus network can transmit real time data to the AV devices on the other 1394 bus in a different place via IEEE 802.15.3.

Home network is a network composed of devices in home and is being expanded by evolving devices. Also, The number of digital contents in home network has been increasing steadily. But it is difficult to continually protect the rights of digital contents due to lack of interoperability among contents devices. Besides, a license has to be re-issued by DRM sever for contents transfer between devices. Thus, this paper proposes framework which can freely transfer and contents to another device through mutual device authentication and a system that can decrease overload of license management of the DRM sever and that enable device outside home network to use contents through user authentication.

Advances in technologies of networking, chip integration, and embedded system have enabled sensor networks applicable to a wide range of areas. Sharing some common characteristics, sensor networks are thus diversified in features depending on their applications. An intelligent and digital home can be one area to establish a particular feature of sensor network. This paper proposes a composite sensor and control network, and discusses its applying to the next generation intelligent and digital home. Development results of the network and a test-bed as a virtual test environment are also presented. The proposed network can not only be efficiently applying to achieve new home intelligences but also provide a sound solution to maintenance and operations of home network or devices.

The development of digital technology makes our life more convenient in our lives and its calmness promotes the qualify of our life. Digital-home-automation system lets indoor-living more free, safe and clear so that it really has come true our life style that considers our mind and healthy to be important. Moreover, LED light source that combines the semiconductor with the digital technology has been tried as a current indoor illumination. Also the Introduction of the light which has a high technology, like LED light, has been required in living space. It shows that it is very important to have an illuminated-plan which is accepted as well-developed technology This study deals with the investigation into the user satisfaction of the existing residential area illumination and the investigation Into the user satisfaction of the LED illumination being supplied for commercial area now. In the result, the fact is investigated that the user wants the introduction of the digital technology in the illumination because of a backward the residental area illumination in the circumstances being digital gradually. The inconvenience of the illumination used now should be minimized and the development of the LED illumination is a way satisfying the desire. The intended illumination project of the residential area should be accomplished according to the lifestyle of a changing residence.
