TV UT; *Two Way Televi ion ABSTRACT Under an experimental license issu din 1978, KSL-TV in Salt Lake City, Utah, provided 126pages of tel text information to its viewers. In choosing thissystem, the stati n had to decide between it and a videotext system. Althoughvideotext systems permit two-way communication, usuallyover telephone UT, teletext broadcast technology is much cheaper.The Cost fo a decoder, a critical factor in the consumer's'accoptance of e ther system, is ,expected to decline for both technologies.In tel text, access cost is zero, while in videotext theinformation provi er has the option of charging users. It'is possiblethat videotext' interactive capability and superior graphics willincrease rt penetration into paying households. Although teletextand videotext provide similar mass market services, videotext has substantiallymore flexibility and speed. Since systems currently beingused in different countries are incompatible, establishing,technical standards inthe areas of data format, transmission,a d display is of key importance. Current trends and the growing home co1iptermarket favor the growth of videotext, but KSL-TV's experiment howed the value of teletextas an interim information system. -

Home Computer on the Line - the West German BBS Scene and the Change of Telecommunications in the 1980S
Home Computer on the Line - The West German BBS Scene and the Change of Telecommunications in the 1980s Matthias Röhr 1. Introduction On the evening of 16th June 1987, the system operators of five German bulletin board systems (BBS) received unexpected visitors. Accompanied by the police, officials of the “Deutsche Bundespost” (Federal Post Office) searched the homes of the juvenile computer enthusiasts for evidence of violations of the “Fernmeldeanlagengesetz” (Telecommunications Device Act), in particular the connection of modems or acoustic couplers to the telephone line without official postal approval. The postal officials seized the devices and the home computers (Chaos Computer Club 1987). The young people visited by the Bundespost had experimented with their home computers. They had connected them to the telephone net- work to enable other home computer owners to call them and exchange data and texts via the telephone line. Thus, the home computer was no longer just an isolated device, but a communication tool from which the callers could connect to each other. On such a bulletin board system, home computer users could exchange files, have discussions and gain ac- cess to information otherwise difficult to get. For some politically-minded computer enthusiasts of the 1980s like the members of the Chaos Computer Club in Hamburg, BBS seemed the ideal medium for a “digital counterpublic”. BBS were a freely accessible and non-censorable medium, ideal for publishing politically relevant in- formation which otherwise would have remained unpublished.

Survey of Important Issues in UAV Communications Networks
1 Survey of Important Issues in UAV Communication Networks Lav Gupta*, Senior Member IEEE, Raj Jain, Fellow, IEEE, and Gabor Vaszkun technology that can be harnessed for military, public and civil Abstract—Unmanned Aerial Vehicles (UAVs) have enormous applications. Military use of UAVs is more than 25 years old potential in the public and civil domains. These are particularly primarily consisting of border surveillance, reconnaissance and useful in applications where human lives would otherwise be strike. Public use is by the public agencies such as police, endangered. Multi-UAV systems can collaboratively complete missions more efficiently and economically as compared to single public safety and transportation management. UAVs can UAV systems. However, there are many issues to be resolved provide timely disaster warnings and assist in speeding up before effective use of UAVs can be made to provide stable and rescue and recovery operations when the public communication reliable context-specific networks. Much of the work carried out in network gets crippled. They can carry medical supplies to areas the areas of Mobile Ad Hoc Networks (MANETs), and Vehicular rendered inaccessible. In situations like poisonous gas Ad Hoc Networks (VANETs) does not address the unique infiltration, wildfires and wild animal tracking UAVs could be characteristics of the UAV networks. UAV networks may vary from slow dynamic to dynamic; have intermittent links and fluid used to quickly envelope a large area without risking the safety topology. While it is believed that ad hoc mesh network would be of the personnel involved. most suitable for UAV networks yet the architecture of multi-UAV UAVs come networks has been an understudied area.
