history of Cable tv Networking
History of CATV
The history of community Antenna Television is very interesting. Johan Walson was the man who introduces the CATV first time in 1948. Walson have a sale store of TV sets in Mahanoy city, Pennsylvania where he sale the TV sets. This is a hilly area where reception of TV signals was poor. So he was facing a lot of problem regarding the sale of TV set. One day he installs an antenna on a mountain near the city and lays a coaxial cable from antenna to his shop.
Now he got good picture on his TV set. That day, in June 1948 was first CATV setup displayed on the shop of Johan Walson. He also laid a cable from shop to the home of his costumer to satisfy about reception of TV set. To provide good quality reception of TV signal to his costumer he added an amplifier in cable and charged 100$ for installation and 2$ per month.
History of Cable TV in Pakistan
The Cable TV CATV introduced in Karachi in early 90’s. This was a small scale network in basement of a building, providing only 3 to 5 channels including PTV. In 1990 many broadcast channels started Satellite transmission which made the cable TV more attractive for the viewers. With the passage of time cable TV spreads too many cities, but all these cable operators were not registered by the government of Pakistan.
The private broadcasting era starts in 1990 when Network Television Marketing (NTM) starts its transmission and former name of its channel was Shalimar Television Network (STN). It was a joint project of government and private sector, in which government holds 45% share. Pakistan Electronics Media Regularity Authority (PEMRA) came into being in 2002, and resulting the revolutionary change in broadcast domain of the country.
Cable TV Network there are two types of CATV networks are providing services in Pakistan. One is analog CATV network and other is Digital CATV network. Both are discussed below.
1. Analog CATV network
In this network operators obtain the channels from different sources like satellite TV, terrestrial TV and from CD/DVD VCR player in form of AV signal and feed these signals to the modulators. Modulator provides RF modulated signal at its output. The RF output of all modulators is combined in RF mixer and provide to an amplifier which transmit this signal on a coaxial cable.
This is a very simple type of network. This network can expend within a limited area. If the expansion of network is increased the quality will be low and cost will be increase. The main problem of this network is maintenance of quality.
Modern Technology
2. Digital CATV
In digital CATV network all setup is same like in analog CATV setup. The operator collects programs from different sources like Satellite Channels live local TV channels, or CD/DVD player. They achieve the signals through Digital satellite Receiver or cameras or CD/DVD player in Audio Video form.
This AV signal is then provided to the MPEG-Encoders which convert these signals in MPEG-2 format; these encoders are also called MPEG encoders. All encoder’s outputs are combined in a MUX, this multiplexer single output is provided to Modulator and then one amplifier/converter is used to transmit this signal on optical fiber. All these encoders Multiplexer and Modulators are controlled and monitored through a NMS (Network Management System).
At user end a set top box is used to convert this signal in RF form to view the signal on television set. This set top box has some important functions like online recording video games and request for VOD.
3. DTH Network
The DTH service provider collects the TV programs from different sources for example: satellite news, entertainment and sport channels or terrestrial channels, combine these channels to make a package and transmits this channel package to their user via satellite link. This transmission is digital and encrypted so user receives superb video result. This is a conditional access transmission. There is another option for user and that is video on demand. The main difference in this setup is Program monitoring system. This is system where contents of programs, coming from different sources are checked according to policy of that organization. The service provider takes the satellite transponder on lease for different type of packages. The NMS is used for monitoring, network controlling, encryption and link management purpose. At user end a small dish antenna and set top box is used to receive the signal. This set top box has some important functions like online recording video games and request for VOD.
Advantages of DTH over CATV
• The core advantage of the DTH is that you will pay only for those channels which you have subscribed; it is not like CATV that you are getting bulk of unwanted channels.
• The second advantage of DTH is picture and audio quality of a channel,
• DTH provides program recording options for subscriber.
DTH is not much expensive as compared to CATV because it costs according to the number of channels subscribe by the user.
• For live matches DTH provides selectivity option to view matches from different camera angle.
• Coverage on remote areas where wired transmission is not possible
• Main and big advantage of DTH-TV entertainment is for whole family. All the programs which are for viewers, fully censured
II. DTH in Asian Countries
In India there are 110 million TV viewer in which 68 million has the facility of cable and satellite systems. The penetration of DTH subscriber is 5% of total cable and satellite user. In 2010 the DTH subscriber was 10 million. According to a research report of Barat Book, “India DTH market forecast of 2012” the numbers of DTH subscriber is forecasted to grow at a CAGR around 29% during 2009 to 2012. Same as in other Asian countries like Indonesia, Vietnam, Philippine is also big markets of DTH-TV.
Cable TV in Gilgit
The Cable Television Network was introduced in Gilgit in early 2000’s. This was a small scale network in basement of a building, providing only 10 to 15 channels including PTV. Firstly in this region cable TV transmission were transmitted through Analogue system. With the passage of time cable TV spreads too many villages of Gilgit, but all these cable operators were not registered by the government of Pakistan. Now many cable operators are trying to convert their networks on digital system.

Danyore area
Danyore is a village in the namesake Tehsil in the district Gilgit lies across the river Gilgit in the outskirts of the regional Capital of Gilgit-Baltistan. Danyor is famous for its lush green fields, and poplar trees. The world's highest paved road KKH passes through the beautiful landscape of the village .the important places in Danyore are The Shrine of Shah Sultan Alif above the Danyore tunnel,[2] the Chinese Graveyard near the Karakoram Highway and the rock inscriptions in the Chikas locality are the widely visited tourist attractions.
The Danyor Suspension Bridge, which was constructed over a half century ago, is quite a wonder; it connects the KIU Campus to the village. The Danyor end of the bridge enters a tunnel constructed by locals without any proper civil engineering equipments some 5 decades ago one of the important and historical things in danyore is Danyore Suspension Bridge.The Danyore Suspension Bridge is in Gilgit-Baltistan and is one of the oldest make shift suspension bridges in the region. The bridge connects Danyor to the premises of the Karakoram University across the River Hunza. Currently the bridge is closed for vehicles and only pedestrians are allowed to pass through. There has been constructed a two way concrete bridge beside it, that is being used as an alternative which was completed in 2013.
Before the construction of the suspension bridge of Danyor there used to be a boat which is locally called Jaalo (a traditional raft for the passage crossing rivers and lakes) was used to cross the Hunza River. The bridge was constructed in mid-sixties. The Danyore side of the bridge is connected to a tunnel that was dug by the then residents of Danyore without any engineering tools and equipments almost a decade later.
