ITU-R Recommendation BT.2020, more commonly known by the abbreviations Rec. 2020 or BT.2020, defines various aspects of ultra-high-definition television (UHDTV) with standard dynamic range (SDR) and wide color gamut (WCG), including picture resolutions, frame rates with progressive scan, bit depths, color primaries, RGB and luma-chroma color ...
Samsung NX1 - First prosumer camera to record in HEVC, 4K downsampled from 6.5K, 80 Mbit/s in H.265. 30 min max recording time limit Samsung NX500 - Same 28 MP APS-C sensor as NXI but 4K video is not downsampled from 6.5K so less details and more noise than the NX1 - with this 2.4× crop factor the kit lens become a 38–120mm f8.5–13.4 ...
The first mobile phones to be able to record at 2160p (3840 × 2160) were released in late 2013, including the Samsung Galaxy Note 3, which is able to record 2160p at 30 frames per second. In the year 2014, the OnePlus One was released with the option to record DCI 4K ( 4096 × 2160 ) at 24 frames per second, as well as LG G3 and Samsung Galaxy ...
A BT.656 data stream is a sequence of 8-bit or 10-bit words, transmitted at a rate of 27 Mword/s. Horizontal scan lines of video pixel data are delimited in the stream by 4-byte long SAV (Start of Active Video) and EAV (End of Active Video) code sequences. SAV codes also contain status bits indicating line position in a video field or frame.
In May 2019, mobile phone vendors started releasing the first mobile phones with 8K video recording capabilities, such as the ZTE Nubia Red Magic 3 series. [26] This is enabled by the sufficient resolution of image sensors used in mobile phones, and by the sufficient chipset performance. However, mobile phones with up to 5K (2880p) or 6K (3240p ...
HLG is supported in Rec. 2100 with a nominal peak luminance of 1,000 cd/m 2 and a system gamma value that can be adjusted depending on background luminance. [3] For a reference viewing environment the peak luminance of display should be 1000 cd/m 2 or more for small area highlights and the black level should be 0.005 cd/m 2 or less. [ 3 ]
The maximum bit rate value in the sequence header of the MPEG-2 video stream is 19.4 Mbit/s for broadcast television, and 38.8 Mbit/s for the "high data rate" mode (e.g., cable television). The actual MPEG-2 video bit rate will be lower, since the MPEG-2 video stream must fit inside a transport stream.
The color encoding system is known as YCbCr 4:2:2. The Rec. 601 video raster format has been re-used in a number of later standards, including the ISO/IEC MPEG and ITU-T H.26x compressed formats, although compressed formats for consumer applications usually use chroma subsampling reduced from the 4:2:2 sampling specified in Rec. 601 to 4:2:0 .
