4k resolution 4096 x 2160pi)els asde*ned +# ,i%ital Cinema Initiati$es-,CI.

It is also called /Super 0i%h ,e*nition

It has ei%ht million pi)els on a sin%leima%e

What is 4K?

4K is 2idel# used to descri+e an ima%e ha$in%a+out our thousands horizontal pi)els

4K is a term de*ned +# ,i%ital CinemaInitiati$e -,CI. in !((3

,CI speci*cations o 4K are as ollo2s' 4(5horizontal pi)els and !(46 $ertical pi)els

Tele$ision industr# has adopted 7ltra0, 870,9 2ith resolution "64( : !15( pi)els

as its 4K standard;ideo streamin% industr# allo2s a resolution

o upto 4(5 : !"(4 pi)els

A

Rou%hl# our times that o 0,,ata size o a t#pical 4= ima%e *le is 4( B

The ima%e is "5+itDpi)el and 4(5 ) !15(pi)els

;ideo requires !4 or 46 ps' hence data size ora ! hour mo$ie is 5>6 T or 14 T

7ncompressed 4= $ideo requires A>6 +ps+and2idth or $ideo streamin%

Compressed streamin% can reduce +and2idth

FGE!((( can reduce the +and2idth to"((B+ps

35inch or 54inch

Sharp uses plasma technolo%# and

displa# size is 13!inch
