    Can we please use this as an opportunity to standardise on common framerates worldwide? There's really no need for the 50i/60i - 25p/30p split anymore.

    ... and thinking about it a bit more, why not support just 24p/48p/72p for drama/studio tv/sports?

    I was fortunate to get tickets to see this. The frame rate was 60p but the plan is to increase it to 120p

    Too many standards across the regions. 720i 1080i 720p 1080p 24p 25fps 50fps 30fps 60fps all encoding nonsense etc. While all this might sound like a child's play to tech heads it creates a lot of incompatibility and unwanted worries.
    Instead of rushing to 4k why don't they try to make one freaking standard across the globe? Start selling TVs/DVD/BR etc. that support ALL formats not just PAL or NTSC etc. And then gradually fade them away into TVs that have unified set of codecs etc.
    Whole commerce and marketing makes people forget that they have one life and instead allowing them to relax and enjoy it just keeps bombarding with "new" rubbish every year if not quarter.
    When I look back 4-5 years and now - yes there are some fancy tech but nothing revolutionary and certainly nothing amazing for the same price of i.e. TV set 4-5 years back.

    Not likely to have stuff on a small disk at that kind of resolution unless compression gets very very good indeed.

    It will, see this article about H.265 :

    Hmmmm, we'll see when its released.

    I tend to be a tad skeptical over stuff these days having watched such things as the hype about 3G which fell flat when it actually got traction.

    Regarding H265 there will have a been a tradeoff somewhere, the question is where.

    SMPTE 292 which states the standards for HD creation was released in 98 and it took this long for them to get it even partially implemented. The announcement of a standard means very little towards actual adoption of it in content creation, let alone broadcast.

    tbh i think H265 still isnt really enough to get 4/8k into a reasonable OTA spectrum without introducing artefacts. Your taking about 2 x or 4 x the raw data with these resolutions and the new codec can at best, bring it in line with what is used for current 1080p.

    The whole point in these super high res images is that everything should look relatively in focus which would be ruined by over-compression and eliminate the point in doing it in the first place.

    QUad-layer Blu-ray should be good for the 4K if encoded with the new H.265.

    TV shows are multiplexed together into a single stream for broadcast, so when you change channel you are no longer necessarily changing the frequency of the spectrum you are looking at anymore, you are either changing which mpeg stream within the multiplex you are looking at or changing to another multiplex altogether.
    Im pretty sure that for this to work, the reference clocks used at either end (by the encoders/decoders) would have to be the same frequency and mixing it up would make things extremely difficult.
