TV newspapers in ISDB-multimedia information broadcasting services

TV newspapers called PRESENT are multimedia information broadcasting services which provide information programs consisting of text, still pictures, video, and sound. PRESENT is an important application of ISDB and provides interactive programs with easy operation. This paper first describes the basic functions of the multimedia information broadcasting services, interactive program presentation, multimedia structuring, and indexing. Second, systems for realizing interactive presentation in the broadcasting services are discussed and the stored reception system is found to be appropriate for the PRESENT system. Multimedia structuring methods are also discussed and the layout structure, the logical structure, and the hyper-link structure for PRESENT are optimized. It is shown that the automatic indexing method plays an important role in providing effective information access for users. Finally, these services are tested using the experimental PRESENT system which is designed to use satellite broadcast data channels     

Image processing on the IBM personal computer

The Palo Alto Scientific Center has developed an experimental image processing system based upon the IBM Personal Computer. It provides a variety of commonly used image processing functions in an environment that connects the programs through a menu convenient for both casual and experienced users. The System is implemented using a compiled BASIC program coupled with assembly language subroutines. Its performance is impressive, providing interactive multispectral image processing and image analysis capability for small images.     

Simulation analyses of weighted fair bandwidth‐on‐demand (WFBoD) process for broadband multimedia geostationary satellite systems

Advanced resource management schemes are required for broadband multimedia satellite networks to provide efficient and fair resource allocation while delivering guaranteed quality of service (QoS) to a potentially very large number of users. Such resource management schemes must provide well‐defined service segregation to the different traffic flows of the satellite network, and they must be integrated with some connection admission control (CAC) process at least for the flows requiring QoS guarantees. Weighted fair bandwidth‐on‐demand (WFBoD) is a resource management process for broadband multimedia geostationary (GEO) satellite systems that provides fair and efficient resource allocation coupled with a well‐defined MAC‐level QoS framework (compatible with ATM and IP QoS frameworks) and a multi‐level service segregation to a large number of users with diverse characteristics. WFBoD is also integrated with the CAC process. In this paper, we analyse via extensive simulations the WFBoD process in a bent‐pipe satellite network. Our results show that WFBoD can be used to provide guaranteed QoS for both non‐real‐time and real‐time variable bit rate (VBR) flows. Our results also show how to choose the main parameters of the WFBoD process depending on the system parameters and on the traffic characteristics of the flows.

Interaction,extraction and analyses of consumer reviews: A novel e-billboard system

With the growth of Internet and electronic devices, the position of multimedia advertisement is getting more and more important. Our research aimed to combine this new technology with a web page to design a novel interactive e-billboard system which can collect consumer emotions. We developed an interactive e-billboard based on Kinect motion sensing camera. The system provides a friendly user interface for users and improves the exposure rate and quality of advertisement with a two-way interactive communication. The back-end system captures consumer emotions actively. The data collected will be used as a reference for the follow-up marketing strategy analysis.
