Whether you only need a few frames in order to compute frame N, because of fairly frequent i-frames, or whether you need every frame before N to compute N, the DVR can still compute each frame, and so skip anywhere it wants(unless, of course, it was physically unplugged/off/not getting a usable signal, I'm sure customers with flaky reception are going to love having minutes of artifacts after every dip...

      The Beeb is a public broadcaster that operates under a Royal Charter, basically they can do whatever they want as long as they fulfill that charter (which is, in case you haven't been paying attention is to be a public broadcaster).

Not only do other networks pay the BBC for rights, but there's DVD sales, toys and merchandise, books and what not. When the BBC does make a profit, that money is funnelled into other productions (news, web services, other shows) Doctor Who probably pays for a bunch of BBC shows.

    this munges up the keyframes (I frames) in a stream when it detects a cue embedded by the network (ADS START HERE!!1!). therefore, if a device is designed to fast-forward by skipping over the predicted (P and B) frames, it cannot do this as it can't find the I frames needed to display anything at all.

    this will fail on sane devices because fast-forward is usually implemented as skipping just the B-frames (that are predicted off both I and P frames), while decoding the I frames and P frames.

    this will further fail because MPEG-2 decoders are fast enough that they can decode the stream in it's entirety fast enough for a practical fast-forward (my 5 yo computer can do it on CPU only, 1 core only at about 200fps).

    this will fail even further because a trivial firmware hack could detect this "cue tone" and skip the ads _entirely_. they're basically implanting a trivially readable signal that usefully tells us what are the ads and what is the show.

This type of patent is in no way clever, or anything that couldn't have been thought up by anyone working in that field (and by quite a few people not skilled in the field of video compression and transport). Yes, I agree that in detail it may not "have been done before" and thus not subject to prior art, but the "obviousness" clause is meant to protect the patent pool from accumulating with patents that do nothing but hinder progress. ie. If a patent doesn't provide useful non-obvious information (or information that wouldn't naturally be derived with a trivial amount of calculation or tinkering), then allowing it to be used to extort others that come up with a similar or the same concepts can only harm an industry as a whole.
