MPEG2???
哥们你搞笑么?
数字院线什么时候用MPEG2了
标准
* 2D Image:
o 2048x1080 (2K) at 24 frame/s or 48 frame/s, or 4096x2160 (4K) at 24 frame/s
+ In 2K, for Scope (2.39:1) presentation 2048x858 pixels of the imager is used
+ In 2K, for Flat (1.85:1) presentation 1998x1080 pixels of the imager is used
+ In 4K, for Scope (2.39:1) presentation 4096x1716 pixels of the imager is used
+ In 4K, for Flat (1.85:1) presentation 3996x2160 pixels of the imager is used
o 12 bits per color component (36 bits per pixel) via dual HD-SDI (encrypted)
+ 10 bits only permitted for 2K at 48 frame/s
o CIE XYZ color space
o TIFF 6.0 container format (one file per frame)
o JPEG 2000 compression
+ from 0 to 5 or from 1 to 6 wavelet decomposition levels for 2K or 4K resolutions, respectively
+ Compression rate of 4.71 bits/pixel (2K @ 24 frame/s), 2.35 bits/pixel (2K @ 48 frame/s), 1.17 bits/pixel (4K @ 24 frame/s)
o 250 Mbit/s maximum image bit rate
* Stereoscopic 3D Image:
o 2048x1080 (2K) at 48 frame/s - 24 frame/s per eye (4096x2160 4K not supported)
+ In 2K, for Scope (2.39:1) presentation 2048x858 pixels of the imager is used
+ In 2K, for Flat (1.85:1) presentation 1998x1080 pixels of the imager is used
+ Optionally, in the HD-SDI link only: 10 bit color, YCbCr 4:2:2, each eye in separate stream
* Audio:
o 24 bits per sample, 48 kHz or 96 kHz
o Up to 16 channels
o WAV container, uncompressed PCM |
