需积分: 7 107 浏览量更新于2024-06-28 收藏 4.3MB PDF 举报

CEA-861-F-2013标准是由美国消费者电子协会(Consumer Electronics Association, CEA)制定的一份针对未压缩高速数字接口的数字电视(DTV)配置文件。这份标准发布于2013年5月，旨在通过消除制造商与消费者之间的误解，促进产品间的互换性和性能提升，帮助消费者快速选择并获得适合自己特定需求的产品。标准的目的是建立一个公开、透明的框架，以确保市场上的产品能符合一致的技术规格，同时并不限制非成员企业生产和销售不符合标准的产品。该标准的核心内容聚焦在第二块EDID（Extended Display Identification Data）上，这是一种电子设备用于自我识别和报告其显示能力的数据结构。EDID的第二块包含了更详尽的视频和音频特性信息，如支持的分辨率、刷新率、色彩深度、音频格式等，这对于确保高清晰度电视(HDTV)的兼容性和性能至关重要。它还可能涵盖了诸如色彩空间、信号带宽、连接器类型等关键参数，这些数据对于系统设计者、制造商和消费者来说是决定设备是否能够无缝集成和高效运行的重要依据。 CEA-861-F-2013标准要求设备厂商在生产过程中提供准确的EDID信息，以便消费者可以根据这些信息了解设备的具体功能和限制。此外，该标准还强调了知识产权保护，指出未经IHS许可，任何形式的复制或网络传播都是不允许的。这确保了标准的完整性以及市场秩序。 CEA-861-F-2013是IT行业中显示技术领域的一个重要规范，它规定了高清数字接口设备的接口规范、性能指标以及数据交换方式，对于推动电视行业的技术创新和产品质量提升起到了关键作用。遵循这一标准，不仅有助于消费者做出明智的选择，也有利于制造商实现产品的标准化和市场的公平竞争。

2.2 Definitions

For the purposes of CEA-861, the following definitions apply.

2160p—A progressive CE Video Format with VIC in the range 93 through 107 and having 2160 active

vertical lines (Vactive) lines per Video Frame.

Active Format Description (AFD)—A data structure that describes what portion of the Picture actually

contains useful information (e.g., letterbox and pillarbox Bars are not considered useful information). It is

a 4-bit field like that standardized in ETSI TS 101 154 [49], but whose exact meaning may depend on

whether the data is delivered per ATSC/SCTE or ETSI standard. See Section 6.4 for details. Note that the

use of the term “active” in this definition is not consistent with the use of this term in other portions of

CEA-861 and most of the other documents referenced by CEA-861.

Active Image—The useful portion of the image contained within a Picture. Active Image excludes

letterbox and pillarbox Bars (see Annex N).

--`,,```,,,,````-`-`,,`,,`,`,,`---

CEA-861-F

Active Line—A Video Line occurring during the Vactive period(s) containing both Active Pixels and Blank

Pixels. Active Pixels and Blank Pixels fill the Hactive and Hblank portions of these lines, respectively (see

Annex N).

Active Pixel—A Video Pixel that conveys Pixel Data (see Annex N).

Adobe

RGB

—The optional RGB (opRGB) color space defined in IEC 61966-2-5 [33]. See also the Adobe

RGB (1998) Color Image Encoding Specification [70].

Adobe

YCC601

—The luma-chroma-chroma (YCC) color space defined in Annex A of IEC 61966-2-5 [33].

The ITU-R BT.601 [6] color conversion matrix is used to transform RGB values to YCC values.

Auxiliary Video Information (AVI)—Additional information (defined in CEA-861) related to the video

being sent from a Source to a Sink.

A/V—Audio and Video.

Bar Data—Data that enable computation of regions of the image that are outside of the Active Image

within a Picture, for example areas of zero or uniform luminance (i.e., Bars).

Bar Pixel – An Active Pixel that conveys a portion of a Bar (see Annex N).

Bars—Region of the display screen that is being driven or scanned at either zero luminance or at a

uniform luminance; or regions of a Picture that are intended to be driven (e.g., matrix addressed) or

scanned (e.g., cathode ray tube (CRT)) at either zero luminance or at a uniform luminance. In other

words, it is the portion of the Picture that does not contain useful information (see Annex N).

Basic Audio—Uncompressed, two channel, digital audio. Exact parameters are determined by the

interface specification used with CEA-861 (e.g., 2 channel IEC 60958-3 [12] L-PCM, 32, 44.1, and 48 kHz

sampling rates, 16 bits/sample).

Blank Pixel—A Video Pixel that carries data other than Pixel Data (see Annex N).

Blanking Line—A Video Line occurring during Vblank period(s) containing only Blank Pixels. Blank

Pixels fill both Hactive and Hblank portions of these lines (see Annex N).

Byte—8 bits of data.

CE Video Format—Any Video Format listed in Table 1 except the 640x480p Video Format.

CEA Extension—The E-EDID Standard [9] defines a VESA-assigned tag (0x02) that allows for an

extension to be added with additional timing formats.

Coded Frame – A (compressed) signal representing a rectangular array of Coded Pixels containing an

image that may, in whole or part, be eventually rendered onto a display.

Coded Line – A horizontal line of Coded Pixels output by a video acquisition function (e.g., a

decompressor or a camera aperture).

Coded Pixel – The colored component samples of a single picture element (pixel) output by a video

acquisition function (e.g., decompressor or a camera aperture).

Color Component Sample—A value that conveys a portion of the total information about of a picture

element (pixel). A Color Component Sample may be a red sample (R), green sample (G), blue sample

(B), a luma sample (Y) or chroma sample (C).

CEA-861-F

Component Depth—The number of bits used to represent a Color Component Sample. It is generally

denoted as N.

Compressed Audio—All audio formats other than L-PCM and One Bit Audio.

Content Pixel – An Active Pixel that conveys a portion of the Active Image (see Annex N).

Digital Television (DTV)—A device that receives, decodes, and presents audio and video material that

has been transmitted in a compressed form. The device can be a single unit or it can be constructed from

a number of individual components (e.g., a digital terrestrial STB and an analog television).

Direct Stream Transfer (DST)— A lossless compression scheme for the Direct Stream Digital audio

format.

DTV—Defined in CEA-861 to be an EDTV, HDTV, or SDTV. A Sink can also be any combination of these

terms. A DTV with an uncompressed video input is also considered a Sink.

Dual-Aspect Ratio DTV—A DTV that simultaneously supports both Picture Aspect Ratios of a Video

Format Timing (e.g., 720x480p). Listing both formats in the EDID data structure at the same time signifies

simultaneous support.

Dual-Aspect Ratio Timing—A Video Format Timing (e.g., 720x480p) that is available in both Picture

Aspect Ratios (16:9 and 4:3) with no difference in the timing for the two formats.

EDTV—A DTV capable of displaying 720x480p in 16:9 or 4:3 Picture Aspect Ratios. See Section 3.2.

Full Range—R, G, B or Y Quantization Range that includes all code values. See Section 5.4.

High Definition Television (HDTV)—A DTV capable of displaying a 1920x1080i or 1280x720p Video

Format in 16:9 Picture Aspect Ratio. An HDTV also has EDTV capabilities. See Section 3.2.

High Definition (HD)—A CE Video Format that, inclusively, has 720 to 1080 active vertical lines (Vactive)

lines per Video Frame.

InfoFrame—A data transfer structure for sending miscellaneous information from a Source

to a Sink over a CEA-861 interface. Various InfoFrames are described in Section 6.

Interface Development Organization (IDO) – The organization (e.g., HDMI LLC, HDMI Forum, VESA)

responsible for the CEA-861 implementation that is present.

Interface VSIF – One or more VSIF(s) defined by the IDO.

IRE Unit – A percentage of reference white with respect to black (i.e., blanking level). Reference white is

assigned a value of 100, blanking a value of 0.

IT Video Format—Any Video Format that is not a CE Video Format. Specifically, any Video Format not

listed in Table 1 plus the 640x480p Video Format.

Limited Range—R, G, B or Y Quantization Range that excludes some code values at the extremes. See

Section 5.4.

Multi-channel Audio—Digital audio with more than two channels, for example, L-PCM or AC-3.
