    The AC who also responded got it right. The repetitive data is not in the transport stream, 8VSB does a great job of maintaining the integrity of the data it carries.

    I'm a hard person to impress, but every time I learn more about 8VSB I am amazed. The engineers who devised that system are freakin brilliant. It is... amazing to run an 8VSB signal through a device that can add interference and see just how much RF crap you can create before your signal even hiccups.

    Furthermore, within the actual demodulator part, there is a fair amount of extra working done to determine which taps are which

    One way to determine the signal quality of an 8VSB signal is to plot a constellation graph which ideally should look like a set of 8 vertical bars and with your points lining up along one of those bars. Just last week we were working with a new Broadcom chip that was decoding a signal which, according to the constellation graph... was garbage and should not have been able to be decoded. It did an amazing job of filtering (as is the job of the demodulator, not an external device).

    Provided INDUCE doesn't pass... such a device could be sold legally, hell, we already sell systems which can do this and much, much, much more, but at 30-50k a pop, it's overkill for a consumer (albite everything we manufacture and sell is overkill for a consumer.)

    The trick of selling this device would be labeling it as a packet restamper, allow a user to specify what pids to restamp and to what. Yes, you could use it to remove the broadcast flag from OTA transmissions, but that would be illegal.

    Hence, you could argue substantial non infringing use, however for such an argument you'd need to show some reason as to why you'd want to restamp pids in a transport stream and nothing else.

    Broadcasters do pid restamping all of the time, however they also modify the pat and pmt's accordingly as well... the solution mentioned above would be incapable of that as described, however a little extra Veralog code could do it.

    As I do not know electrical design at all, I've been meaning to plug a couple of PCI card solutions we sell (cheapest of the 2 runs 2k) and have someone build me a new Xilinx load (~1 hour of their time), this will get me by provided I can find some old prototype boards.

    I should mention another drawback of this device... it would only work on one channel at a time, and every time you change the channel on your receiver, you'd have to do so on this device in order to see programming.

    You mean I have to wait til then to hack it?

    I work for a company that builds systems for use with digital television and when I 1st read of the proposed broadcast flag and it's implementation I had a very easy to do bypass method devised in a matter of minutes. In fact, beating this broadcast flag will be child's play and will not even require 'hacking' a receiver or any modifications to it.

    The OTA digital tv signals you receive in your home contain an ATSC Transport Stream, based on an MPEG-2 Transport Stream, as part of the ATSC standard, (A/53 I think) where the broadcast flag was mandated.

    Within the transport stream, there are packets each of 188 bytes long; the broadcast flag carries a packet PID of 0xA0, (again I could be wrong but it has been a few months since I looked into the specific pid values).

    In order to beat the broadcast flag, one would need a simple box with a pair of 8VSB tuners with a Xilinx (or other FPGA) in the middle. The 1st tuner would demodulate the signal and pass it into the Xilinx whose sole job would be restamping pids, should it come across a packet with the pid denoting that it is carrying a broadcast flag, it could simply change the pid of this packet to 0x1FFF (a null packet). On the other end, the 2nd tuner would modulate the signal back into 8VSB and to what ever you might have receiving. The beauty of this solution is that null packets carry no payload in a transport stream, thus would be ignored by anything down stream.

    All in all, a device like this would cost about $100 (even in mass production) as tuners and FPGA's are generally not cheap.

Once added, any MWP users using FirstAlert will hit the database, see that the message is there and act accordingly (often times deleting without even showing it to the user). It works... ok, about 30% of my spam is nuked this way, the built in Bayesian filtering catches another 40% or so, and the DNS blacklists catch most of the rest.
