Now and again a programme on ITVX will simply stop and throw me back
to the menu, where I have to navigate back to it and press "Resume".
It doesn't happen very often but I haven't seen this on the other
services, so maybe they've underestimated the server capacity they
need to run the service. Whatever it is it's definitely them, not me.
Everything on iPlayer (last time I checked) is streamed at 50fps.
Everything on the other terrestrial catchup services, including ITVX,
is streamed at 59.94fps,even though most of it will have been shot for
British television. I think this may account for the occasional
glitch, though not for severe buffering.
(The utility app for the Amazon Fire stick wrongly indicates the frame
rate as 59.93, not 59.94, but that's another story).
It seems absolutely nuts to me that material originally shot at 25 frames/second (or 50 fields/second) should be shown at any other
speed, and it's difficult to believe that the only available versions
of the analogue originals would have been converted to American
analogue standards before being presented for digital streaming. The
BBC can do it correctly, as can Amazon and Netflix (which have some TV
material as well as movies).
Amazon and Netflix actually change the frame rate depending on what
the material is - 23.76, 24, 29.97, 30, 50, 59.94 (wrongly shown as
59.93) or 60 fps as appropriate.
I assume that when a movie is shown at one of the fractional values it
means that the only available version is a recording originally
scanned for American analogue television. Recent cinema movies shown
on Amazon or Netflix are generally shown at 24fps.
In the days of analogue broadcast television and cathode ray tube TVs
with tuned diode-pentode line output circuitry it was important that
the broadcast signal kept the same synchronising signals at all times,
so anything originated on different standards had to be converted
first, but modern digital displays can handle changes in frame rate
perfectly well. There's no reason not to show everything at the frame
rate at which it was originally shot (provided the original is
available of course). Maybe the terrestrial TV companies think they
have to run a streaming service to the same technical standards as an
analogue broadcast service and nobody has ever questioned it.
