Dan, Hugh,
3:2 pull-down could perfectly be one of the most confusing subjects in digital video.
The 3:2 pull-down in film based sources (as done on 480i DVDs for example) adds 6 frames to the 24
of the original film data, but it does it at the field level, to end up with 30 frames of 60 fields
on the interlaced output of the player (Svideo, composite, component, etc). A progressive DVD
player takes that image and further doubles up the frames to 60 fps for the component or digital
outputs of the player. The beauty of that is that all the video processing is done in the digital
domain within the DVD player (avoiding D/A conversions for each step). There are some web sites
that graphically explain the concept better than just words.
A digital TV would take that progressive 480p 60fps output of the DVD player and display it without
using its internal doubler, which is generally better (done on the DVD player). A digital TV using
the 480i 30fps version from the player would have to perform the 480p conversion for display using
the TV circuitry (jump from 30i to 60p).
Video sourced material that started as 30i would not need to do the 3:2 pulldown, but it would
doubled up to 60fps for display progressively by the TV.
Apply the same logic to 1080i and 1080p.
A film based 1080p 24fps movie, hopefully stored in Hi Def DVD as interlaced with flags to cleanly
reconstruct each of the 24 frames, would typically need to go thru a pull-down processing (of
fields) to reach the 1080i 30 fps level for interlaced outputs of the player (so any 1080i TV can
display it), and also do frame doubling to get to 1080p 60fps for the progressive output of the
player (for 1080p TVs that have that input), the DVD disc does not need to waste space by storing
the film movie as 60 fps when the originals shots only have data for 24fps.
After that is done in the player, it would output the signal via HDMI as 1080p 60fps, and a capable
HDTV would "accept" it and map its pixel grid for display at 60 fps, IF the TV is able to accept it.
This method is cleaner than the alternative of distributing the video processing tasks between
player and TV even when between the two a digital connection has modernized the link.
Although one can assume, by tradition, that with a digital connection, the player would do a better
job internally, one never knows which of the two (player or TV) would do a better job until both
circuitries are tested, for which the player and the TV should ideally have the ability to handle a
switchable input/output of 1080i and 1080p 24/30/60 fps, then the viewer would decide which video
processing looks better and set in the menu the player and TV accordingly, if the option is given.
If the TV does not even receive 1080p (at any frame rate) there is not much one can do. One is
cornered to the only option of: let the TV do all the frame doubling video processing from the 1080i
version of the DVD player (which means that a Hi Def DVD player must supply the downgraded 1080i 30
version even when a potentially better 1080p 60 internal processing might be available in the player
(the $1000 player), specially on film, stored as 24fps interlaced with flags to reconstruct the
frames easily.
If the HDTV is a CRT it would end up in an analog stage to drive the tubes, for which additional
conversions have to occur.
A 72 Hz projector (or plasma Elite) would have the capability to process the image to be displayed
as 72 from 24, which is exactly 3 times without needing 3:2 pulldown, just frame tripling (3:3 they
call it).
The perfect scenario would be to have also that 72 Hz option in addition to all of the above options
of 1080i and 1080p 24/30/60 fps on both player and TV set "on all" of the inputs/outputs (it should
come with a hamburger as well, if you know what I mean), but most 1080p sets can only display at 60
fps anything that is fed to them, and Hi Def DVD players are expected to only use HDMI for 1080i,
not component analog; who knows what they would do for 1080p outputs?, if anything is done at all.

Hello All,
I'm a long time lurker (first time poster) to the tips list. It has been a valuable source of
information for me and I appreciate all the contributions.
I'm a bit confused about what Rodolfo said about 3:2 pulldown though. Specifically the following:
'24fps of film gets more complicated than the above because it has to be converted to 30 with 3:2
pulldown and then to 60 with the 1080p doubler of frames.'
I thought 3:2 pulldown (2.5x) produced 60fps from 24fps film (3 then 2 then 3 then 2) and did not
need an additional doubling. Correct me if I'm wrong (which is often the case).
By the way, my interest in HD television began in 1997 and I bought my first DLP projector in 1998
(Runco VX1). I've since built a few HTPCs (or what I like to call HEPCs, Home Entertainment PCs,
heh). Anyway, thanks again for the contributions and clarification of the above.

Dan, Hugh,
3:2 pull-down could perfectly be one of the most confusing subjects in digital video.
The 3:2 pull-down in film based sources (as done on 480i DVDs for example) adds 6 frames to the 24
