main

This system is basically to distribute the signal from different satellites to all the TV points in the building. By installing this system it will be possible to watch the channels from these satellites using digital receiver in each TV point. It is possible to distribute up to 16 polarities using this system

IF Distribution - ADVANTAGEMost economical SMATV SystemPossible to watch a lot of channelsPossible to install the PAY TV decoders in each TV pointsCan subscribe the PAY TV channels individually

No possibility for centralized channel line-up Individual tuning of receivers is necessary when there is some

changes in satellite parameters Not possible to control the type of channels to be received. (Any

channels coming through the satellite can be viewed) Not possible to distribute any in-house channels through the

system. The active components are kept in various location hence the

system will be less reliable & difficult to maintain.

IF Distribution - DISADVANTAGE

R.F. DISTRIBUTION SYSTEM

This is the oldest way of distributing the channels. As per the system, a head-end station will be installed and the signal received from satellite will be converted into RF channel and will feed to the distribution network. We can connect the TV directly to the wall socket and tune the channels.

TWO OPTION TO SET-UP HEAD-END STATION

OPTION 1

Utilizing individual receivers for each

channel in the head-end station. The

output will be fed to the modulators.

OPTION 2

Professional receiver modules will

be used which will convert the

signal directly from the satellite to

RF Channels.

The option1 will be more economical compared to option 2 but, this will be more professional and reliable. smatv main

RF Distribution - ADVANTAGE The channels are tuned in the Head-End station. Hence specified

channel list can be created. Possible to distribute the PAY TV channels through the system In-house channels can be added in the system No receivers in the rooms hence single remote for the TV The channels can be tuned directly on the TV.

The number of channels that are able to distribute are limited to a maximum of 95 channels.

The distribution network is analogue hence the disturbance of local channels and others are common.

Due to analogue distribution network, it is not possible to ensure the same picture quality in the all the TV’s.

The HD reception is not possible using this system.

RF Distribution - DISADVANTAGE

DIGITAL CABLE TV SYSTEM(DIGITAL RF)

The digital cable TV system utilizes the latest technology called QAM/COFDM technology. The digital cable TV system is like an RF system but it has more advantages than RF system. As per this system, Head-End station will be installed to convert the signal received from the satellite to a QAM/COFDM signal in RF range. This signal will be distributed to each TV point using the RF distribution network.

DIGITAL CABLETV (DIGITAL RF) - ADVANTAGE

More number of channels can be distributed through RF network. The Head-End station is located in one place hence the maintenance

will be easy and the system will be reliable. The picture quality in all the TV’s will be perfect The HD channel distribution is possible in the system The existing RF system can be replaced with this system without

disturbing the hotel operation The existing coax network can be utilized, additional wiring is not

needed. PAY TV channel can be subscribed and distributed centrally. In-house channel distribution is possible using this system.

Interactive services are not possible If the TV’s are not having digital tuner then additional set-top-box

are necessary

IP TV SYSTEM

This is the advanced and latest TV system available in the market. This system will have an IP head-end station which will convert the signal from the satellite to IP stream and will be distributed to various TV points using data network. A Middleware server will be added to the system to make it possible to add a lot of interactive services along with TV channels

IP TV SYSTEM - ADVANTAGE The system gives HD reception in all TV points The system offers a lot of interactive services

The system is much expensive compared to the other system The existing RF distribution network cannot be used for this

system A separate network has to set up for distributing the signal

which may cause interruption to hotel operation and creates more financial expense.

The quality of data distribution network will affect the performance of the system.
