The design and implementation of a Web-browser based interface to CEBus networks is described. The interface supports browsing and navigation of a CEBus network and the user can interact with CEBus devices on the network, and access and control CAL context and object structures within these devices. The interface can be used to access a local CEBus network from a standard desktop PC, or from a Web-TV or set-top box system with built-in CEBus interface hardware. Furthermore, as the interface is implemented using conventional Web-browser technology it can also serve as a full Internet interface to a home network which provides an Internet/CEBus gateway. Such a system can provide access and control services to the home network from any computer with an Internet connection.

Multimedia teaching materials and networks providing various kinds of digital information are expected to improve the efficiency in various kinds of learning. Interactive communication between instructors and individual students is thus becoming more important, particularly in classes with a large number of students, because such classes typically have less communication and looser relationships. Ordinary Q&A systems are composed of very simple buttons fixed on desks, and their functions can not be easily extended. More intelligent teaching systems composed of desk-top computers and keyboards connected by a local area network (LAN) are high-cost and lack flexibility because of their fixed wiring. For low-cost installation and flexible application, wireless communication is needed, and each student terminal should have a micro-computer, a small liquid crystal display (LCD), and an input device. We have developed a wireless instructional system composed of simple intelligent terminals. This system supports personal interactive communication (PIC) between the instructor and each student during lectures. As shown in Table 1, the PIC system handles student registration, interactive Q&A, and the monitoring of each student's class participation. The instructor's terminal first maps the student IDS to the terminal IDS, allowing the instructor to identify the students present. When the instructor asks a question, the students input their answers. The student terminals then transmit their data to the instructor's terminal, which can show the instructor an individual's answer or a summary of all the answers. Additionally, by monitoring the activity at each student's terminal, the computer can advise the instructor when a student would like to ask a question or if the student is losing interest. The advantages of this system are several: (1) students can respond to instructor's questions without suffering psychological stress; (2) teaching efficiency is greatly

As computer and consumer electronics converge, a new digital interconnect capable of transporting real time digital video and audio as well as device command is needed. Industry standards and protocols for the various applications are vital to inter-operability amongst these devices. The combination of the IEEE 1394-1995 standard and the IEC 1883 specification lay the framework for digital video, audio and command transport. These standards and protocols are implemented as a combination of hardware and software in two novel integrated circuits’.

We present an electronically controlled adaptive monitor that displays stereoscopic views changing with the position of the observer's eyes without requiring any additional devices such as glasses. Alternatively, the monitor can also be used as a highresolution two-dimensional screen. For the transmission of stereoscopic image data we suggest a modified MPEG coding that provides depth-information of objects.

Different possibilities of reducing the memory needed in MPEG2-video-decoder-architectzrres are shown and discussed. The memory of an MPEG-decoder consists of the input buffer, the reference picture memories and apicture output buffer used for progressive to interlaced conversion. The reference picture memories and the picture output buffer are considered for reduction. The most promising approach of reducing the reference picture memories requires twice the calculation power of the usual approach and will show signifxant memory savings for the higher levels of MPEGZ.

This paper presents a post-processing algorithm for low bit rate videoconferencing on ISDN lines. The relatively few images per second that are transmitted during low bit rate multi-media communications are up-converted after decoding inside the terminal receiver to an increased frame rate of 25 Hz or 30 Hz, depending on the display. Applying advanced motion estimation and compensation techniques can achieve a significant improvement in motion portrayal of moving objects.

To reduce the size of a picture it needs to be lowpass- filtered in horizontal and vertical direction before being sampled down to avoid aliasing. This lowpass-filtering can be combined with the MPEG-decoding-process due to the character of the discrete cosine transform. Equipped with some flexibility an MPEGZ-video- decoder can be used for decoding more than one video stream with reduced image size. It is shown how memory and calculation power can flexibly be used for decoding MPEG-sequences with reduced picture size.

This paper discusses a high quality alternative to an MPEG-2 codec which can be integrated into an MPEG-2 transport stream. The demands which would necessitate such a hybrid are the desire for high quality video at bandwidths well below those anticipated by the MPEG-2 standard, or the desire to provide product differentiation by increased quality at existing bandwidths. Solutions are discussed for implementation of this algorithm on existing processors for possible deployment applications such as set-top boxes.
