Q.1 : I am a regular reader of your Satellite Dish Channels Magazine. I have read the Trouble Shooter column of the January 2002 issue which states that NGC Adventure channel is available on Apstar 2R satellite (3720 H, SR = 29265, FEC 5/6) and is free to air. I have tuned my 8 feet dish to Apstar 2R but the channels received are scrambled except DD North East which I am able to receive clearly. I want to know if NGC Adventure is free to air and why I am not able to receive it ? In the Trouble Shooter column another reader had indicated that WWF is available on Ekushey TV on Fridays between 5:30 PM & 6:30 PM in the evening. I have tried watching Ekushey TV but have not been able to see it.

Ans: Dear Mr. Sohail, the NGC Adventure channel was removed from the Apstar satellite in February. It is now broadcast as a digital scrambled channel from the AsiaSat 3S satellite. The good news for all WWF fans is that these programmes are now carried on the TEN Sports channel.




Q.2 : In your Channel Guide page could you please categorise clearly the channels as "FTA (free to air)", "PAY," "Analog", "Digital", so that it can be easily understood by anyone.

Ans: In the Channel Guide, the Free-To-Air channels are listed against their name as "FTA".The pay channels are usually mentioned as being scrambled by listing the scrambling technology used - "Viaccess" or "PowerVu" or "NDS" or "Mediacast" or "Nagra" etc. All digital channels whether FTA or Encrypted can be easily identified as those in which a symbol rate and FEC are indicated.




Q.3 : We already have a cable network service. In our place one more network is going to commence. Please let us know whether the cable laid by the new setup will affect the transmission telecast of the first setup? If at all how?

Ans: In an ideal situation there will be no interference across the 2 cable TV networks. However, Cables, particularly poor quality co-axial cables do not provide very good shielding. As a result, the signals from one network can "plunge" into the other, if the 2 cables run side by side and close to each other. The best way to avoid "cross plunging" is to ensure that your Amplifiers and Cables are not fixed close to those of the other network. We understand this will be difficult in practice, since you will often have to compete for customers in the same area or sometimes even in the same building. However, if you could work out some mutual understanding, it will be beneficial to both of you.




Q.4 : Dear editor, I have a problem in receiving Indian channels. I do not receive Aaj Tak on InSat2E at 83 degrees. Any changes in the channel? 2. I would like to know whether there are any channels available on INSAT 2B/2C in digital format after the commissioning of the new satellite INSAT 3E.

Ans: The Aaj Tak channel is available on the Insat 2E/3B satellite located at 83 deg. East. However the signals are scrambled and require the use of the decoder supplied by the channel in order to be able to receive it. At the time of writing this reply, the only channels currently available from the INSAT 2C/2B is DD-North East as an analog signal and DD-Ahmedabad as a digitally compressed signal. It is expected that these two would also be removed from this satellite finally and the traffic on the satellite will be mainly VSAT & telephony.




Q.5 : Dear Sir,Your technical articles are quite good. Could you please explain in details the following: 1. What is the PID and SID of a channel ? 2. What is the symbol rate of a digital channel? Is it directly related to the picture quality of the channel? There is a difference in picture quality of different channels.

Ans: Dear Shahid, PID & SID are Identifiers of the channels and the satellite service being received by you. These are normally auto-tuned by the satellite receiver. Symbol Rate can be briefly described as the rate at which the downlink of data from the satellite to your receiver takes place. It has no bearing on the picture quality, but does indirectly affect the same if the data speed is not sufficient.




Q.6 : Earlier I used to receive DD Malayalam via a satellite. I am now staying in Oman and do not receive the channel. How do I receive it? Has it gone digital?

Ans: Dear Mr. Ram, DD-4 Malayalam has been shifted to the (New) INSAT 3C satellite 74 deg East. Its new freq. is 3.901 GHz. Unfortunately, the new footprint does not cover the Middle East, and is effectively a Spot Beam covering India.




Q.7 : Dear Technical Editor, Please compare RHCP & LHCP Polarisation with Vertical & Horizontal.

Ans: Polarisation is a method, which enables 2 different TV programmes to be transmitted from the same satellite, simultaneously, at the same frequency, without interference. This has become necessary with the advent of large Satellites, each with a large number of transponders. Today, it is not uncommon to have a single Satellite capable of 24 or even more 'C' band transponders for Television broadcasting.In such cases, the use of cross polarisation, either LHCP / RHCP or Right / Left is absolutely necessary. CIRCULAR POLARISATION: Circular Polarisation offers the option of Right Hand Circular Polarisation (RHCP) or Left Hand Circular Polarisation (LHCP). Some earlier books referred to these as Clockwise and Anti-clockwise Polarisation. The Intelsat and Russian Satellites such as the Gorizont series extensively use circular Polarisation. (New Skies Satellites - NSS is an offshoot of Intelsat and also utilizes Circular Polarisation). LINEAR POLARISATION: Linear Polarisation can be vertical or horizontal. Most modern day Satellite operators except Intelsat and the Russian Satellites use linear polarisation. These include PanAmSat, AsiaSat, Thaicom, the INSAT Series etc. Theoretically Circular Polarization offers slightly better polarization in Rain affected areas such as the Equatorial region, particularly where the signal strength from the satellite is low. However, most modern day satellites provide high signal strength, which does not yield any significant advantage between Circular and Linear Polarization.




Q.8 : Dear Sir: I am the fan of your magazine Dish Channels last three years. I want to buy a digital receiver which has to receive all decoded channels. Please tell me which receiver is the best in the market? Please give me an advice. Thanks

Ans: Dear Mr. Mansoor thank you for yours intrust in our magazine, there are many brands of digital receivers in the market but we suggest you can buy Neosat, Eurobox and Winnersat digital receiver. These digital receivers are very simple to use. You can receive free to Air and all decoded channels with the help of Smart card.




Q.9 : Dear Editor, can you tell me where I can get the TB6 channel. Please inform me where I can receive this channel?. Thank you !

Ans: Mr. Masood, TB6 channel is not coming since last 3 to 4 months. You can't receive this channel from any other satellite. If this channel is available on any other satellite, we will inform you in our magazine.




Q.10 : Dear Sir: I have a Winner sat WLR-12. Can I receive digital channels with this receiver? Please tell me I am waiting for your answer. Thank you !

Ans: Mr. Insaf, Winnersat WLR-12 is an Analog receiver you can't receive digital channels with this Analog receiver. You have to buy a digital receiver, its price is between Rs.9000- 11,000/= in the market.




Q.11 : Dear Editor, I have a digital free to air receiver. I want to install that receive on Nilesat with the K.U Band LNB. Please tell me how can I receive Nilesat digital channels? Please help me.

Ans: Dear Shaukat, if you install your digital receiver on Nilesat satellite you need a 12ft solid dish, on that satellite you will get many free to digital channels, also on Nilesat have Show Time package. These channels are subscriptions based. If you subscribe these channels you will get 22- channels,this package is called Movie plus and other package is called Total Plus package. Total Plus package has 26 - channels. You will get Indian and English entertainment channels.




Q.12 : Dear Editor, I am the fan of your magazine Dish channels, I bought this magazine every month. Sir,I have a 6ft and 12ft dish, Winnersat 912 receiver and Gardiner LNB. I am receiving Sahara TV, PTV World, MTV and Jain TV from that dish. But when I try to receive Arabsat 2/3, I can't search the Arabsat 2/3 channels on that dish. Please tell me if there is any other instrument will be required to find the satellite position? Please give me the information in your magazine or by post. Thank you !

Ans: Dear Rashid did you try on your 6ft dish or 12ft.If you try on 12ft dish you get the Arabsat 2/3 cahnnels.First you have to know the elevation of that Satellite. If know that fix it.




Q.12 : Thanks for your earlier reply. While going through your February magazine I came across the advertisement of Echostar Digital Receivers. In the advertisement there is a mention of "Viaccess Embedded" 1. What does this mean? 2. If we buy this receiver will we be able to receive all the Viaccess channels?

Ans: Viacess is a Conditional Access Technology, which permits reception of a scrambled signal only when an authorised "SMART CARD" is inserted into a suitable Satellite Receiver. The Viacess Technology can be built into the receiver as standard. Alternately, the receiver may have a Conditional Access Slot into which a Viaccess "SMART READER" slot can be fitted by the end user. As you can imagine there are other competing Technologies besides Viaccess. Hence, the option of a receiver without a built-in Viaccess module gives the end user more flexibility. However, the cost of a Receiver with embedded technology would usually be lower than one, which accepts multiple modules, with each module paid for separately.
