I still think relying on Mtnl for Tv services id something too much
It's like that if my tel line go down i need not worry i have a mobile for back up , if my broadband goes down we have mobile gprs and other wireless connection however if my Tv goes down then i switching to Radio or Doordarshan would be torture.
Also Tv is a family matter whole my family will yelling on me for unseen saas bahu episodes.

comeon .. dont do this to MTNL.

u have replacement for phone = mobile
replacement for broadband = gprs /wireless connection

why cant u have cable TV as well just in case IPTV goes down?

dont be unfair to MTNL comeon!!

No man ... I meant will u be the bet6a tester of IPTV for me!lolzz

and that ip is a constant for me .I mean every time it connects to that BAS!
[/b]

u got IPTV? or r u going to sponsor me? i can give it a try all at ur expense!

LOL.

 

[mtnlpacked]

lolzzzzz... I will get iptv ,don't worry about that ! it will be in late Jan 2007 when cas is implemented.Will compare both and then get it!Can i have your credit card so that i can sponsor you for the beta testing rightnow...Topic Closed![As it has let to crap]

A friend of mine is living in USA and has comcast iptv connection.He said that it uses another connection but using the same modem.The vci and vpi values will be different than that of broadband's.For internet its 0 and 35 respectively and maybe 0 and 32 or whatever.And only the hardware knows where the hell the content is stored in the server.The codec they use is not available for pc right now.So the software way is not possible atleast for now.Why hate the STB? Its cool cos it has hardware decoding and real time processing.If u wanna record all the channels all the time through decades then buy a big server that has nice fat memory just for some billion bux and nice 6 MP HD-DVD recorder too or a Bluray recorder if there is any .

I got this idea just now. IPTV is plain internet protocol TV that is it works on network interface.
Even MTNL wants CPE with multiport i.e. multiple ethernet ports.

Now in my opinion, IPTV STB does nothing but captures IP packets and converts them to
TV signals. This is similar to streaming video that we see on the net.

My question is, is there any software which captures IPTV packets and displays it on
computer? This way we will save STB deposit and its monthly rent! And being software
based STB we can even record stuffs easily at scheduled time and day. And almost
unlimited data can be recorded based on harddisk space.

I think it should be possible. I havent googled for this. Now I will go and do that!
Mean time u can ponder too.

I did some research and it seems my idea is possible and is already being worked
upon, here is the link:
http://en.wikipedia.org/wiki/Internet_tele...rnet_television
http://en.wikipedia.org/wiki/LinuxTV

I will have to ask MTNL/IOL but I doubt if they will be knowing anything about all these.[/b]


Guys Im Sure we can use the Same Old ADSL Modem For IPTV.
Its Only a Matter Of forwarding the ports to recieve the IPTV.

umm?

The idea sounds feasible Amish but whether its possible is hard to tell.Have you posted the same on more tech-oriented forums, or have u searched them even.The biggest obstacle AFAICT is the encryption part and possible the lack of a standard since its so new and all.Not that a comp can't do encryption but the idea is to keep it secret so that no one can break it, not really that great cos zomeone will break it or has already done so.In any case keep us updated on your latest findings.

I think it should be possible to watch IPTV directly on you PC/laptop. Because an IOL engineer who came to my house for troubleshooting used his laptop instead of the STB. He was playing it through VLC media player while the laptop was connected to the modem. I asked him out of curiosity whether I could do the same on my laptop, but he said- NO. But I doubt, he might have denied it just for the sake of confidentiality policy of his employer!

I don't know if any specific authentication or decryption need to be done by the computer. Also, I wonder how all the interactive functions performed by STB can be handled by a 3rd party computer software like VLC player, unless it is customized in some way by the service provider! I didn't see him doing such things, but he could change the channels at least. I am very curious to have ability to watch it on my computers. No, it's not about cheating or hacking their system, it is just about having extra convenience for my authentic/legal subscription.

I found this interesting article which says that we can probably do this just by knowing concerned IP address and the port number of streaming server(s)! May be these numbers can be found in the initial settings they program in the STB. If I knew this before, I could have remembered it and would have given VLC player a shot!!!

A set top box receives the signal, decrypts it, decompresses it and sends it to the tv. If you can create a software that does the above, then it will work.

But consider the following:
1. Hardware based decoding and decompression solutions are x times faster than software ones.
2. How will you get the information from the card onto the pc - via smart card reader?

You will need atleast one box to disassemble it and see what it does. Then you can go about creating your solution. But remember one thing. The schemes used are similar to DTH boxes. The only difference is that IPTV gets the signal in the form of packets as compared to some other type (what is that?) of DTH. If you can break open IPTV, why can't you do the same with DTH? And what about the legality of the same?

Consider the encryption/ decryption cycle. Lets take an example.

A wants to send a 100M video file to B. What is the fastest and most secure way to do the encryption? How to do it? Like so:
[*] A generates a single key and uses it to apply symmetric encryption to the file (using AES).
[*] A then uses B's (RSA) public key to encrypt the AES key.
[*] Both pieces are sent to B.
[*] B decrypts the key using his private key.
[*] B then uses the AES key to decrypt the video file.
[/list]This is simple if the transaction has to take place between two people.

What about three? Say A wants to send the same file to B and C. But each should only be able to decrypt it using their own private key. This case, when extrapolated, leads to the problem that the DTH and IPTV folks have solved. I think it happens like this:
[*] A encrypts his public key using B's public key and hands this over to B.
[*] A encrypts his public key using C's public key and hands this over to C.
[*] A generates a single key and uses it to apply symmetric encryption to the file (using AES).
[*] A then uses his own (RSA) private key to encrypt the AES key.
[*] Both pieces are sent to B and C.
[*] B decrypts A's public key using his private key. He then uses this key to decrypt the AES key.
[*] C decrypts A's public key using his private key. He then uses this key to decrypt the AES key.
[*] B and C then use the AES key to decrypt the video file.
[/list]
The decompression should be pretty easy as mpeg2/ mpeg4 is involved. Seems feasible?

right looks like they are sending the stream of the IPTV on some port for testing purposes by the engineers...

@gregory_house,sure, h/w decoding will be fast, but with today's computers it's not that big deal doing it in s/w either. Also, open softwares are more likely to be state-of-the-art, more capable, with more features etc.Regarding the card, I am not too sure if the BSNL IPTV STB needs it in the first place. I *guess* the stream *may* not be encrypted when it reaches your LAN (after the modem). Because I feel it is limited to a particular phone line and the content is reasonably secure in the sense if somebody wanted to steal it, he/she needs to have-1. a physical connection to that particular phone line2. username/password for that particular broadband connectionWhereas in case of digital cable or satellite DTH, the same signal is reaching each and every customer's premises. So obviously demand on security may be very different (very high). In these cases, STB would be a must because it has to convert incoming signals into computer readable format (and the other way too, for interactivity), whereas in case of IPTV the modem itself is enough to create network signals with which any PC can interface directly.All that said, it is fair enough to expect or hope to enjoy digital audio/video (for which you are paying) directly on the PC without additional analog links inside STB and tuner cards! Imagine how convenient it would be to get it through WiFi In fact video on the laptop, even in full screen mode, looked much better and sharper than the TV!
