CEA-708-D-2008 数字电视（DTV）闭路字幕[适用于: CEA CEA 数字电视闭路字幕装置（DTVCC SET）]

CEA-708-D defines DTV Closed Captioning (DTVCC) and provides specifications and guidelines for caption service providers, distributors of television signals, decoder and encoder manufacturers, DTV receiver manufacturers, and DTV signal processing equipment manufacturers. CEA-708-D may also be useful in other systems. CEA-708-D includes the following: a) a description of the transport method of DTVCC data in the DTV signal b) a specification for processing DTVCC information c) a list of minimum implementation recommendations for DTVCC receiver manufacturers d) a set of recommended practices for DTV encoder and decoder manufacturers The use of the term DTV throughout is intended to include, and apply to, High Definition Television (HDTV) and Standard Definition Television (SDTV). 1.1 Overview DTVCC is a migration of the closed-captioning concepts and capabilities developed in the 1970’s for National Televison Systems Committee II (NTSC) television video signals to the digital television environment defined by the ATV (Advanced Television) Grand Alliance and standardized by ATSC. This new television environment provides for larger screens and higher screen resolutions, as well as higher data rates for transmission of closed-captioning data. NTSC Closed Captioning (CC) consists of an analog waveform inserted on line 21, field 1 and possibly field 2, of the NTSC Vertical Blanking Interval (VBI). That waveform provides a transport channel which can deliver 2 bytes of data on every field of video. This translates to a nominal 60 or 120 bytes per second (Bps), or a nominal 480 or 960 bits per second (bps). In contrast, DTV Closed Captioning is transported as a logical data channel in the DTV digital bitstream. DTV-specific closed captioning is allocated 9600 bps for each program. This increased capacity opens the possibility for simultaneous transmission of captions in multiple languages and with multiple reading levels, as well as the transport of an entire CEA-608 datastream1. The DTV standard also accommodates a variety of increased horizontal and vertical resolutions (e.g., 704x480, 1280x720 and 1920x1080), versus the single 525 vertical scan line format for NTSC. These added resolutions provide for more defined representations of character fonts and other on-screen objects. The heart of any DTVCC caption display is the caption “window,” which is similar to the window concept found in many computer Graphical User Interfaces (GUIs). Windows are placed within the DTV screen, and caption text is placed within windows. Windows and text have a variety of color, size and other attributes. CEA-708-D describes the above issues in a reverse-hierarchical (i.e., low-to-high level) fashion. It follows an “Open Systems Interconnect (OSI) Reference Model”-type protocol stack for layered protocols. DTVCC consists of 5 protocol layers: the Transport Layer, the Packet Layer, the Service Layer, the Coding Layer, and the Interpretation Layer. The discussion of the first 2 layers is a detailed presentation of data organization issues. The discussion of the last 2 layers provides a more informative presentation of the unique aspects of closed captioning. Some readers may wish to start with these last 2 layers first, beginning in Section 7.

ITU-R REPORT BT.2129-2008 在高清晰度电视(HDTV)节目生产环境里把平板显示器(FPD)作为主监视器的用户要求

Flat panel displays will replace CRT based master monitors in TV programme production, and monitoring, it is therefore urgent that a set of user requirementsbe addressed. Flat panel displays have recently shown display performance closely emulating that of the CRT, as with most technologies the performance characteristics improves over time. It is the aim of this Report to be technology agnostic, although it should be remembered that certain technologies have characteristics that can not be ignored.

One compressed video channel, eight independent audio channels and subcode data are recorded on tape in the digital form. Each of these channels is capable of independent editing. On the following digital video formats, the helical recordings are synchronized to: - 1080 line/59,94 Hz field frequency; - 1080 line/50 Hz field frequency; - 720 line/59,94 Hz frame frequency. These are hereafter referred to as the 1080/60i, 1080/50i,and 720/60p systems, respectively. Similarly, in this standard, the 60 Hz system nomenclature refers to both 1080/60i and 720/60p systems, whereas, the 50 Hz system refers only to the 1080/50i system. Nomenclature 1080 line system refers to both 1080/60i and 1080/50i systems, while the 720 line system refers only to the 720/60p system. The recorded digital video signal shall be compressed according to the DV-based 100 Mb/s specification.
