A new display pointing method for synthesized home equipment

A novel remote pointing system, consisting of a remote-control transmitter to which 8-direction remote-control commands can be input and a receiver which provides cursor moving coordinates on receiving the remote-control commands for icons which visualize predetermined factors to operate various devices in the system, is proposed. Furthermore, a method to realize an operational environment, using a remote-control transmitter employing the proposed method on the basis of TV windows matched with systemized AV equipment, is also proposed. The advantages of the method have been experimentally confirmed by constructing an interactive remote-control environment applicable to a home-HDTV (high-definition television) system. >

Design of home bus controller and its application based on HBS standard

A description is given of features and applications of the software and hardware developed for the home bus controller Japanese Home Bus System (HBS). The network terminations for the twisted-pair wire home bus controller (TP-HBC) applicable to voice/nonvoice terminal remote handling services are described. The authors discuss various application systems, including three experimental terminal services for attaining a compact, flexible, and expandable TP-HBC consisting of one dual microprocessor. It was seen that the designed process scheduler can achieve adequately short switching time for experimental and typical application service implementations. The essential functions and applications were experimentally confirmed, and the global communication capabilities of this TP-HBC were also found satisfactory. >

Telematique Home-Bus System equipped with multi-service switcher function

The development and evaluation of a prototype Telematique Home-Bus System are described. The system contains various communication terminals realized by network terminations (NT) provided with multi-serve switcher (MSS) functions and terminal adaptors (TA) for data communication. The system features and configuration, hardware design, and software implementation are described. The NT and TA were evaluated for three types of terminals, i.e. personal computer with V.27ter modem, G3 facsimile, and telephones. The effectiveness of the Telematique HBS and the NT and TA was found to be satisfactory. >
