本规程描述了电视系统安全操作和安全标题区域的定位方法。本文档旨在应用于程序制作中,其中获取的精华的图像纵横比与显示器的图像纵横比相同。本推荐规程附录B中定义的安全区域是过去实践的遗留。它们基于基于CRT显示器的局限性。建议用户参考SMPTE ST 2046-1了解当前的安全区域,这些区域基于固定像素矩阵显示,并且明显更大。此外,本文定义的安全区域在一个纵横比中生成的材料可能需要以不同的纵横比显示的情况下不提供指导。建议用户咨询SMPTE RP 2046-2了解此信息。安全操作和安全标题区域位于电视系统图像制作光圈格内。
安全行动区指定所有重要行动必须在其中发生的图像区域。安全标题区指定必须限制重要标题信息的图像区域。这些区域确保了动作和标题信息在大多数家庭电视接收器上的可见性。
This practice describes a method for locating the safe action and safe title areas for television systems. This document is intended for application in program production where the image aspect ratio of the acquired essence is the same as that of the display.The safe areas defined in Annex B of this Recommended Practice are a legacy of past practice. They are based on the limitations of CRT-based displays. Users are advised to consult SMPTE ST 2046-1 for the current safe areas, which are based on fixed pixel matrix displays and are significantly larger. Moreover, the safe areas defined herein do not offer guidance in situations where material generated in one aspect ratio may need to be displayed in a different aspect ratio. Users are advised to consult SMPTE RP 2046-2 for this information.Safe action and safe title areas are located within the television system image production aperture lattice. Safe action area specifies an image area within which all significant action must take place. Safe title area specifies an image area within which important title information must be confined. These areas ensure visibility of action and title information on the majority of home television receivers.
