i am currently helping a new internet tv program that has proved to be very popular..the downside to its poluarity is it drew too much attention and ended in court where we subsequently lost. we have been told by a major tv operator that we must block that channel for it to be legal. we are trying to develop a plugin that blocks that single channel then we can release. but the pay tv operator has given us the string to search for in the tv stream but not where to look. the string i know from research is the same string most satelitte companies use to distinguish who pays and who doesnt. the string is "conditional access system ID" which i understand is held in either the closed caption or VTX part of the tv stream. if anyone could help in the location of this string in a given tv stream i would be extremely grateful.
I am not sure, where the string is (analog->videotext, digital->mpeg2-TS=Transport Stream?, PI u.s.w.) .
if anyone can offer help or point me in the direction of someone who knows about the stripping of a stream or an irc channel or another forum etc i would be very grateful.
thanks

Surely the 'Major TV operator' is obliged to tell you where to pick up the ID from?!?!

unfortunately no. the tv company didnt want the program to be released full stop but the judge has said it will be deemed legal if we develop a plugin. therefore the tv company was obliged to tell us what makes their stream unique but they are not obliged to tell us where in the stream this information is held. so we are left looking for the stream and then developing the plugin the plugin part is easy the finding of the string is not as we may know how to program a tv program which is basicaly full screen tv streamed over a new faster bit torrent network. this has nothing to do with actualy breaking down a tv stream into its relevant parts.
thanks anyway any reply is better than none at least the thread is being read

Hello hetster. I noticed that you posted your questions on Toecutters site as well as here. To be honest I think the lack of replies here and there is due to the complex nature of what you are trying to do and probably, with no disrespect to anyone, outside the skills of most ppl involved with the sites.
 
i understand that the question is complex. but it is within the realms of satelitte hacking..it may not be in the normal realm of someone who just puts the codes into a card but there must be someone who actualy knows where the codes are held within a tv stream to be able to extract the new codes to post for everyone else to use. it is really those people that i would like to talk to.
as i dont know my way around the satellite forums i have posted in a few different forums. that is why i say just help in finding the right forum or newsgroup or web site or right person to talk to. any information would be helpful.
the fact i am at least getting replies shows that people are actualy reading the thread and taking it seriously i just hope that the right person reads it at the right time as this program is set to change the way tv is watched. theres not many programs that are taken to court before it is actualy released:)
 
thanks for the info but its not really what i am looking for. firstly logging is no good if this stream gets through then we are in effect breaking the law (will only be a matter of time before someone cracks the prog to allow the stream but thats on their heads not ours).
the prgram works in the fact that and tv stream produced by any tv card anywhere in the world can be shared over a faster bit torrent network..this makes it possible to share tv streams paid or unpaid. the only way we can block is software side not hardware as anyone can share a stream. the only way to blobk the stream is by not allowing a stream with the afformentioned string onto the network to begin with..
i think it might help with what i need if i just give you the homepage then you can see all the details of the prog for yourselves. it is the actual info contained in an uncompressed stream and also a compressed stream as streams will be compressed before they hit the network.

sorry wrong page..click cybersky on left. they are basicaly the same but cybersky is 100% anonymous and uncontrolled


sorry if external links are not allowed but i feel this would help speed up what is needed
 
Why don't you decompile the code from an existing plugin which interprets CA-ID?

I also don't see what's wrong with Llew's suggestion for using logging techniques to ID the datastream component fields. It's only for research purposes, and won't form part of the application. I think you have the legal justification for doing that as part of the ruling you outlined above.

Surely what your application is being asked to do is to filter out any streams that contain a given CA-ID before allowing them to be streamed across a secondary network?

You only need to identify the CA-ID in the native transport stream (assuming that it's your app, or some downstream process that's doing the compression), as you will already have rejected the incoming data from further processing at that point. Surely subsequent processing is irrelevant? If the stream has been compressed before your application sees it, you will also need to know how to decompress it. In that case you will need the compression algo in addition to the CA-ID offset.

As a last observation, don't you think that other providers will examine the existing ruling and claim that the precedent has been set in their favour anyway?

Many of us already stream whatever satellite feed we want across IP networks anyway, and use any number of clients to decode it.

Who was the court case against, I'm guessing it was the Rupert?

Can we download the old version of the software that does not have the
restriction?

you can download the latest beta which is still going ahead while the plugin is being developed.
the court case was filed by major pay tv operator premiere. all details can be found for beta and court cases etc on link above
