On October 13, 2021, DCI approved a new DCI Specification Version 1.4.1 [5] that integrated the 23 errata that had been issued to DCI Specification Version 1.4. For the convenience of users, DCI also created an online HTML [6] version of DCI Specification, Version 1.4.1. Due to the HTML conversion process, the footnotes in the DCSS now appear ...
4096 × 1716 (CinemaScope crop, ≈2.39∶1 aspect ratio) 2K distributions can have a frame rate of either 24 or 48 FPS, while 4K distributions must have a frame rate of 24 FPS. [6]: §3.1.4.2 Some articles claim that the terms "2K" and "4K" were coined by DCI and refer exclusively to the 2K and 4K formats defined in the DCI standard. [8]
2.2 IIA: 16 October 2012: Addresses a breach described above, as well as other flaws in Locality Check; Type 1 extended to preventing content from going to v2.1, 2.0 and v1.x as they all have weaknesses; 2.2 for HDMI: 13 February 2013 This spec is not bound to backward compatibility to v2.0 and v2.1 hence makes it a clean version of v2.2; 2.2 ...
A Digital Cinema Package (DCP) is a collection of digital files used to store and convey digital cinema (DC) audio, image, and data streams. The term was popularized by Digital Cinema Initiatives, LLC in its original recommendation [1] for packaging DC contents. However, the industry tends to apply the term to the structure more formally known ...
Rec. 2020 defines a bit depth of either 10 bits per sample or 12 bits per sample. [2] 10 bits per sample Rec. 2020 uses video levels where the black level is defined as code 64 and the nominal peak is defined as code 940. Codes 0–3 and 1,020–1,023 are used for the timing reference. Codes 4 through 63 provide video data below the black level ...
VESA stated that version 2.0 is the first major update to the DisplayPort standard since March 2016, and provides up to a ≈3× improvement in data rate (from 25.92 to 77.37 Gbit/s) compared to the previous version of DisplayPort (1.4a), as well as new capabilities to address the future performance requirements of traditional displays. These ...
This format has a resolution of 2048 × 1080 (2.2 megapixels) with an aspect ratio of 256∶135 (1.8 962) or roughly "17∶9". [12] This is the native resolution for DCI-compliant 2K digital projectors – active displays with this resolution are rare. The display aspect ratio is frequently wider than the native one, requiring non-square pixels.
Extended Display Identification Data (EDID) and Enhanced EDID (E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g., graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).
