Then again, direct sampling SDR don't have an LO to leak, but do have a stable clock. There are some power supplies and digital systems with spread spectrum clocks. No reason one could not use a spread spectrum ADC clock, heavily over sampled of course, then average the samples where needed. There are some ADC they randomize the data bus for EMC. Do they still have vans in the UK that driving around looking for un-taxed TV?

>Do they still have vans in the UK that driving around looking for un-taxed TV? Yes, well sorta if you say you don't own a TV you'll get an inspection sometime within a period of 1-2 years. The problem in the UK now is that if you have anything with the BBC player on it you have to pay the TV license also. IIRC they also changed the rules regarding TV and now every screen above a certain size is considered a TV because a lot of people were buying flat screens that don't have a tuner installed or removing the tuner to not have to pay the license. For anyone who wonders the cost of the license is 145£ a year that's more than some low cost TV's would go on sales like Boxing Day.

  You're wrong about when you have to pay the TV license. Currently the law states that you have to pay if you watch any streamed live TV (regardless of whether it is from the BBC, Sky or another TV provider). Having equipment capable of watching live TV does not automatically incur the license fee. The law is changing in September, such that you will also be required to pay it if you use iPlayer - however, just having a system that can use iPlayer does not mean you have to pay it - it will be payable only if you use it to watch either live or catch-up TV on iPlayer (other catch-up applications such as ITV's or Channel 5's are not included in this). For some reason, the BBC has decided that either adding a login system or monitoring IP addresses that connect to iPlayer is not the way to go and their official line is that they will continue to monitor usage in the same way as they currently do. There are many long arguments about whether the TV license vans even exist or if they use radio emissions from devices to monitor what you're watching - some contend that flat screen TVs do not produce sufficient emissions, but there is research that says otherwise.

Because it is completely impractical. TV licenses are per property, not per person, so all that would happen is that people would register accounts at a friend's property and keep streaming. IPs aren't tied to specific subscribers, and giving out a database of IPs to subscriber addresses would be a huge breach of privacy (as advertisers can use it also). Plus, frankly, the majority of people pay for their TV licenses and this system would just frustrate legal owners. You'd be deploying a system that may impact less than 5% of viewers, doubt it would even pay for itself.

      Has the snoopers charter gone through yet? Once ISPs are forced to store usage logs it is only a matter of time before TV licensing start attempting to get hold of logs for enforcement purposes.

      Does that balance the rights of the 5% who don't watch live TV but have license officers peering through their windows or (potentially) using detector vans to look through their walls to see what they're watching? I agree neither are perfect (or maybe even good) solutions, but it's still a trade off somehow.
