It looks a bit too neat to be satellite jamming. Firstly it's a tidy cut to black rather with no picture disturbance. Secondly it cuts away before the story even starts, so unless they have access the running order they wouldn't know the story was coming up. So they're obviously watching it on a delay so they can block it before anything appears at all

So they're censoring it after it comes off the satellite but before it's sent out to the public on cable or other distribution system.


Secondly you can't jam a satellite signal on the downlink, you can only jam the uplink by squirting a signal at the satellite from the ground (As happens)

And of course you can't just jam one service, it's the whole transponder or nothing.


I don't know what satellite they use for World News in China but if they were jamming the satellite the other broadcasters on their transponder wouldn't be very keen


World News Asia Pacific is on these satellites:

Notice that on Intelsat 19 it appears 3 times, albeit all encrypted

Yes - I doubt it's jamming. It's far more likely to be a rebroadcast that has been interrupted in the video domain

Look to me like they receive BBC World News, decode it, delay it a little bit to give them warning of something they need to blank, they then cut to black when that happens, and then cut back when the report they want to censor is over. The resulting censored feed is then rebroadcast to Chinese viewers?

In China you have to have permission to install a satellite dish, presumably it has to point to Chinese satellites.
Urban areas have very high cable penetration. Foreign channels such as CNN and those from Hong Kong and Macau are generally only available in hotels, not to residential subscribers.

The headline sequence is usually a good clue to the programme's running order Smile
(But yes, a delay seems likely if they're going to all that effort)
