Adnan Quaium 1 Text Encoding The character by character encoding of an alphabet is called encryption. As a rule, this coding must be reversible – the reverse encoding known as decoding or decryption. Examples for a simple encryption are the international phonetic alphabet or Braille script CSE 4295 : Multimedia Communication prepared by M. Adnan Quaium 2 Text Encoding CSE 4295 : Multimedia Communication prepared by M. Adnan Quaium 3 Morse Code Samuel F. B. Morse and Alfred Vail used a form of binary encoding, i.e., all text characters were encoded in a series of two basic characters. The two basic characters – a dot and a dash – were short and long raised impressions marked on a running paper tape. Word borders are indicated by breaks. CSE 4295 : Multimedia Communication prepared by M. Adnan Quaium 4 Morse Code ● To achieve the most efficient encoding of the transmitted text messages, Morse and Vail implemented their observation that specific letters came up more frequently in the (English) language than others. ● The obvious conclusion was to select a shorter encoding for frequently used characters and a longer one for letters that are used seldom.

Growth of the Internet
Growth of the Internet K. G. Coffman and A. M. Odlyzko AT&T Labs - Research [email protected], [email protected] Preliminary version, July 6, 2001 Abstract The Internet is the main cause of the recent explosion of activity in optical fiber telecommunica- tions. The high growth rates observed on the Internet, and the popular perception that growth rates were even higher, led to an upsurge in research, development, and investment in telecommunications. The telecom crash of 2000 occurred when investors realized that transmission capacity in place and under construction greatly exceeded actual traffic demand. This chapter discusses the growth of the Internet and compares it with that of other communication services. Internet traffic is growing, approximately doubling each year. There are reasonable arguments that it will continue to grow at this rate for the rest of this decade. If this happens, then in a few years, we may have a rough balance between supply and demand. Growth of the Internet K. G. Coffman and A. M. Odlyzko AT&T Labs - Research [email protected], [email protected] 1. Introduction Optical fiber communications was initially developed for the voice phone system. The feverish level of activity that we have experienced since the late 1990s, though, was caused primarily by the rapidly rising demand for Internet connectivity. The Internet has been growing at unprecedented rates. Moreover, because it is versatile and penetrates deeply into the economy, it is affecting all of society, and therefore has attracted inordinate amounts of public attention. The aim of this chapter is to summarize the current state of knowledge about the growth rates of the Internet, with special attention paid to the implications for fiber optic transmission. -

Samuel Morse's Telegraph
1 SAMUEL MORSE’S TELEGRAPH (The Start of the Communications Revolution) Steve Krar We live in the information age where more and more information is required at all times. There never seems to be a time when information is so readily available, but this has not always been the case. The today’s communications revolution includes radio, telephones, television computers, fax machines and satellites. So fast is the change in communications that we sometimes forget the machine that started it all. The Telegraph The telegraph was born at a time when few grasped even remotely what electric current was, let alone what it might do. The telegraph was a landmark in human development from which there could be no retreat. For the first time messages could routinely travel great distances faster than man or beast could carry them. Samuel Morse In October 1832 Samuel Morse, an early pioneer of the telegraph, on his way home from Europe met Dr. Charles Jackson who asked whether electricity took much time to travel over a long wire. The idea began to obsess Morse and before reaching shore, he had sketched the basic elements of a telegraph instrument and a crude version of a code based on dots and dashes. News from Europe in early 1837 told of the great strides being made in telegraphy; Morse realized that if he did not finish the invention soon, his efforts might be wasted. Finally, in February 1837 Congress directed the Secretary of the Treasury to ask for proposals for a telegraph. Morse’s Telegraph Morse thought that if he could perfect the electromagnetic telegraph that he had designed, in 1836, it would answer the government's needs. -
Global Maritime Distress and Safety System (GMDSS) Handbook 2018 I CONTENTS
FOREWORD This handbook has been produced by the Australian Maritime Safety Authority (AMSA), and is intended for use on ships that are: • compulsorily equipped with GMDSS radiocommunication installations in accordance with the requirements of the International Convention for the Safety of Life at Sea Convention 1974 (SOLAS) and Commonwealth or State government marine legislation • voluntarily equipped with GMDSS radiocommunication installations. It is the recommended textbook for candidates wishing to qualify for the Australian GMDSS General Operator’s Certificate of Proficiency. This handbook replaces the tenth edition of the GMDSS Handbook published in September 2013, and has been amended to reflect: • changes to regulations adopted by the International Telecommunication Union (ITU) World Radiocommunications Conference (2015) • changes to Inmarsat services • an updated AMSA distress beacon registration form • changes to various ITU Recommendations • changes to the publications published by the ITU • developments in Man Overboard (MOB) devices • clarification of GMDSS radio log procedures • general editorial updating and improvements. Procedures outlined in the handbook are based on the ITU Radio Regulations, on radio procedures used by Australian Maritime Communications Stations and Satellite Earth Stations in the Inmarsat network. Careful observance of the procedures covered by this handbook is essential for the efficient exchange of communications in the marine radiocommunication service, particularly where safety of life at sea is concerned. Special attention should be given to those sections dealing with distress, urgency, and safety. Operators of radiocommunications equipment on vessels not equipped with GMDSS installations should refer to the Marine Radio Operators Handbook published by the Australian Maritime College, Launceston, Tasmania, Australia. No provision of this handbook or the ITU Radio Regulations prevents the use, by a ship in distress, of any means at its disposal to attract attention, make known its position and obtain help. -
Early Forms of Long-Distance Communication
EARLY FORMS OF LONG-DISTANCE COMMUNICATION In this material, you will learn about Telegraphy, Telephone and GSM architecture Before the development of the electric telegraph in the 19th century revolutionized how information was transmitted across long distances, ancient civilizations such as those in China, Egypt and Greece used drumbeats or smoke signals to exchange information between far-flung points. However, such methods were limited by the weather and the need for an uninterrupted line of sight between receptor points. These limitations also lessened the effectiveness of the semaphore, a modern precursor to the electric telegraph. Developed in the early 1790s, the semaphore consisted of a series of hilltop stations that each had large movable arms to signal letters and numbers and two telescopes with which to see the other stations. Like ancient smoke signals, the semaphore was susceptible to weather and other factors that hindered visibility. A different method of transmitting information was needed to make regular and reliable long-distance communication workable. Did You Know? SOS, the internationally recognized distress signal, does not stand for any particular words. Instead, the letters were chosen because they are easy to transmit in Morse code: "S" is three dots, and "O" is three dashes. The Electric Telegraph In the early 19th century, two developments in the field of electricity opened the door to the production of the electric telegraph. First, in 1800, the Italian physicist Alessandro Volta (1745-1827) invented the battery, which reliably stored an electric current and allowed the current to be used in a controlled environment. Second, in 1820, the Danish physicist Hans Christian Oersted (1777-1851) demonstrated the connection between electricity and magnetism by deflecting a magnetic needle with an electric current. -
Comparative Study of Print Media Coverage of Indian Athletes in London Olympics
Journal of Sports Research, 2015, 2(1): 10-17 Journal of Sports Research ISSN(e): 2410-6534/ISSN(p): 2413-8436 URL: www.pakinsight.com COMPARATIVE STUDY OF PRINT MEDIA COVERAGE OF INDIAN ATHLETES IN LONDON OLYMPICS Asish Paul1† --- Gopa Saha Roy2 1Assistant Professor, Dept. of Physical Education, Jadavpur University, Kolkata, W.B., India 2Assistant Professor, S.I.P.E.W., Hastings House, Alipur, Kolkata, W.B., India ABSTRACT Sports became the most interesting area of media coverage among different stream. As it has got its most important status in the world’s media to popularize the newspaper, there is a distinct lack of comparative research on the media coverage of sports. To minimize the gap, this search draws attention on sports coverage during the London Olympics, 2012 from three different newspapers of different languages. The coverages were recorded considering the preview, competition and review phases. The results show that the total coverage of the English newspaper, the Telegraph (36039 sq. cm.) was more than the other two Bengali and Hindi newspapers (9224 sq. cm. and 2599 sq. cm. respectively). The female performers got more attention (34942 sq. cm.) than the male performers (12920 sq. cm.). All the three newspapers provided maximum coverage in the competition phase rather than the other two phases. The English newspaper provided more attention in preview of the main competition also in comparison to the other two newspapers. It has concluded that the coverage of the print media depends mainly on the performance of the athletes, popularity of the performers and intensity of the competition. -
